Static three-phase electric energy meters FOBOS 3 (hereinafter referred to as meters) are designed for measurements of active and reactive electric energy in accordance with the requirements of GOST 31818.11-2012, GOST 31819.21-2012, GOST 31819.22-2012, GOST 31819.23-2012, measurements of quality indicators of electrical energy ( voltage deviation, deviation of the fundamental voltage frequency, voltage dip duration, voltage dip depth, overvoltage duration) in accordance with the requirements of GOST 30804.4.30-2013 (GOST R 51317.4.30-2008) in three-phase three-wire and three-phase four-wire AC electrical networks with a frequency of 50 Hz

Description

The operating principle of the meters is based on preliminary scaling of input voltage and current signals with their further conversion into digital code and processing, as well as subsequent display on the display of a reporting device or the display of a device for collecting readings of measurement results and information:

Amount of active electrical energy, kWh;

Amounts of reactive electrical energy, kvar h;

Current time values;

Values ​​of electrical energy quality indicators;

The current tariff, taking into account the presence of up to 24 time zones of the day (up to 24 tariff switchings during the day) separately for each day of the week and holidays, with an individual tariff schedule for each month of the year.

The design of the meters consists of a housing and a terminal block cover (clamping board). The housing contains a printed circuit board, a terminal block (clamp board), measuring elements having three current measurement circuits and three voltage measurement circuits in a three-phase alternating current network, as well as a circuit for monitoring the current strength in the neutral wire, auxiliary circuits and a direct current source, load cut-off relay. When sealed, the terminal block (clamp board) cover prevents access to the terminal block screws and power conductors.

The meters are intended for use both as an independent device and as part of information measuring systems and information and computing complexes for monitoring and accounting for electricity.

To transfer measurement results and information to external measuring systems (hereinafter - IS), to communicate with meters for the purpose of their maintenance and configuration during operation, auxiliary circuits of the meter are used, on the basis of which the following can be implemented jointly or separately:

Radio module;

Optical type interface;

Data transfer interface RS-485;

SPI terminal device “Phobos 3” UO3K and UO4K

This article was written for those who do not like to read instructions for devices, and if they do, then only the most important things: how to connect and how to program. These two sections of the instructions for the devices UO3K And UO4K Terminal device SPI "Phobos 3", I will describe in detail. And in the process we will find out what the differences are between these devices.

Connection diagram for the UO4K device.

Connection diagram for the UO3K device.

As can be seen from the diagrams, their connection is quite simple. Both devices are powered by a constant voltage of 12 volts and provide operation in the voltage range from 11.0 to 14.2 volts and at telephone line voltages above 17V. If the supply voltage of the UO-3K and UO-4K is below 11 volts or the voltage in the subscriber telephone line is below 3 volts, then when you try to arm the object, the “POWER” indicator and the remote indicator will light up in a flashing mode with a frequency of 10 Hz.

Since both devices are compact, You shouldn’t collect twisted wires in them, pull a separate wire from each sensor. It is better to install a junction box above the device or above a suspended ceiling (in general, hide it), and make all the connections in it.
And then the installed devices UO-3K and UO-4K will be easy to maintain, and there will be no wires when opening the devices.

Installation procedure.

UO-3K and UO-4K installed on walls or other structures of a protected premises in places protected from exposure to precipitation, mechanical damage and access by unauthorized persons. The remote light indicator must be placed in places that are clearly visible to the facility's economic authority after leaving the protected premises.

Install the device in the following sequence:

a) determine the installation location of the device;

b) mark the fastening, mount the fastening elements;

c) install the device on the fastening elements.

Overall and installation dimensions of the device
UO-4K and UO-3K

Install the device, power supply, AL and connecting lines in accordance with the electrical connection diagram given above. When using an EI reader, the length of the wires to connect it should not exceed 15 m.

Before connecting devices UO3K and UO4K It is necessary to check the correct installation and connections.

Configure the device loops.

For UO3K.

If ShS2 is intended to be used as an alarm loop without the right to be removed, remove the “ShS2” jumper from the device.

If ShS3 is intended to be used as a fire line without the right to be removed, remove the “ShS3” jumper from the device.

Attention! Installing or removing “ShS2” jumpers« And« ShS3« Only do this when the device is powered off. When the power is on, the UO-3K will not respond to jumper changes.

For UO4K.

If ShS3 is intended to be used as an alarm loop without the right to be removed, remove the “ShS3” jumper from the device.

If ShS4 is intended to be used as a fire line without the right to be removed, remove the “ShS4” jumper from the device.

Attention! Installing or removing jumpers “ШС3” and “ШС4”(For UO4K) Only do this when the device is powered off. When power is on UO4K will not respond to jumper changes.For UO3K respectively - "ShS2" and "ShS3"

To enter the device programming mode, perform the following steps:

1. Remove UO4K from security (if necessary);
2. Open the device case (open the case intrusion sensor);
3. Press the RESET key, type on the device keyboard
   “master” code (factory setting “123456”).
4. Press ENTER.

After this, the device should emit a confirmation signal to the built-in sound signaling device, the “POWER” indicator of the device should be turned on in intermittent mode with a frequency of 5 Hz. The indicators ShS-1, ShS-2, ShS-3 and ShS-4 (for UO-4K) are turned off. The device is waiting for the programming mode to be selected.

Select the programming mode according to the table.

table of programming modes Terminal device SPI "Phobos 3" UO3K,UO4K.

1. To program the “master” code, enter the appropriate mode by pressing the “1” key. Next, enter the desired code (from 2 to 6 characters) and press ENTER. The device will signal that the code has been successfully entered and will return to the waiting state for selecting a programming mode.
2. To program arm/disarm codes, enter the appropriate mode by pressing the “2” key. Next, sequentially dial the desired codes (from 2 to 6 characters each), completing the dialing of each code by pressing the “ENTER” key, and a sound signal will sound indicating that the code has been successfully recorded. The mode is exited after recording 10 codes, or after briefly pressing the housing tamper sensor. If there is an error when entering the code, press the “RESET” key and repeat the entry again.

Note.

The serial numbers of the entered arming/disarming codes correspond to the numbers of economic authorities (from 1 to 10) transmitted to the Phobos-3 SPI along with the arming and disarming commands.

It is not allowed to program arm/disarm codes that differ from each other by one least significant unit (for example, “123” and “124”), since a code that differs from the arm/disarm code by one least significant unit is used as a duress withdrawal code.

1. To program electronic identifier codes, enter the appropriate mode by pressing the “3” key. Next, successively touch the external reader of the device with the electronic identifiers (for a period of no more than 1 s), while the remote indicator turns on briefly and a sound signal is given about the successful recording of the code. The mode is exited after writing 10 EI codes into the device’s memory, or after briefly pressing the housing tamper sensor. Label the programmed EIs with serial numbers from 11 to 20.

Note.

The serial numbers of the programmed EI correspond to the numbers of economic agencies (from 11 to 20) transmitted to SPI "Phobos-3" together with the arming and disarming commands.

1. To program an individual device number, press the “4” key. In this case, the device will record a random number from 0 to 15, which will be used as a direction code when transmitting telegrams to SPI "Phobos-3"«.

Note.

To ensure protection against unauthorized substitution of the terminal device, be sure to program the individual device number when installing it on site.

1. To program the relay output functions, enter the appropriate mode by pressing the “5” key. Next, press the corresponding number on the keyboard to select the relay output functions: “1” – for the monitoring station function, “2” – for the ASPT function, “3” – for the “Siren” output function, “4” – for the “Lamp” output function.

1. To program the exit delay time, enter the appropriate mode by pressing the “6” key. Next, press the corresponding number on the keyboard to select the desired delay time: “1” – for a delay time of 30 s., “2” – for a delay time of 60 s., “3” – for a delay time of 120 s. or “0” – no delay.

1. To mark programmed EIs as “lost”, enter the appropriate mode by pressing the “7” key. Next, enter on the device keyboard the two-digit EI number (from 11 to 20) that you want to mark as “lost” and press the ENTER key. Re-entering the same number will remove the mark from this EI.

Note.

When you try to disarm a device using an EI marked as “lost”, the “Alarm” message will be transmitted to the Phobos-3 SPI, and the device indication will correspond to the “Disarmed” state.

1. To program a separate duress removal code, enter the appropriate mode by pressing the “8” key. Next, enter the desired duress withdrawal code (2 to 6 characters) and press ENTER.

The programming mode is exited automatically 60 s after the last key press, or immediately after the case tamper sensor is closed.

2. Cancel an incorrectly entered code by pressing the RESET key (before pressing the ENTER key) and re-entering the code.

Well, now let’s take a closer look at these devices.

Devices UO3K and UO4K absolutely identical in design, connection diagram and configuration. But in the device UO4K, there is an additional cable. This gives us the opportunity to create a second line of security for the facility.

UO3K:

Loop 2 – “CTS” – monitored 24 hours a day. If there is a violation, an alarm signal is sent to the security console and a squad or the State Investigation Bureau is dispatched.

Loop 3 – “FIRE” – monitored 24 hours a day. In the event of a violation, a “FIRE” signal is sent to the security console and a squad or SRT is dispatched.

Basic setup of loops in the device UO4K:

1 loop – “GUARD” – works only when the device is armed; in case of violation there is an entry delay of 30, 60 or 120 seconds. During the entry delay, no alarm is sent to the remote control. And only after the entry delay has expired, an alarm is sent to the monitoring station and a squad or RRT leaves.

Loop 2 – “GUARD” – works only when the device is armed; if violated, it immediately generates an alarm signal to the security panel.

Loop 3 – “CTS” – monitored 24 hours a day. If there is a violation, an alarm signal is sent to the security console and a squad or the State Investigation Bureau is dispatched.

Loop 4 – “FIRE” – monitored 24 hours a day. In the event of a violation, a “FIRE” signal is sent to the security console and a squad or SRT is dispatched.

IN SURVEY: what does the second “Security” loop give us?

ANSWER: if it is used to control windows, emergency exits and the interior of premises, then we receive an early warning to the security console about intrusion into the facility, since this loop is triggered without an entry delay. And if it is violated, the squad or SRT is dispatched immediately.

Conclusion:

UO3K from UO4K The only difference is the presence of one more loop.

"FOBOS 3" - three-phase electricity meter direct, semi-indirect or indirect inclusion with built-in LPWAN radio module.

The electricity meter records the consumption of active and reactive components of electricity and transmits readings and parameters of the electrical network to the user’s personal Internet account.Allows you to quickly and without extra costsdeploy automated systems for commercial electricity metering. Using the FOBOS-3 electric meter, you can quickly and without extra costs deploy an ASKUE system for SNT and cottage villages. At the same time, SNT electricity will be under the full control of the SNT chairman, allowing each kilowatt consumed to be taken into account.

Data from the meter is transmitted via radio channel to the VAVIOT base station,and from it via the Internet to your personal account.Signals from the FOBOS 3 meter have excellent penetrating ability thanks to the protocol NB-Fi, which makes it possible to install the device behind concrete walls, in metal boxes and basementsat a distance of up to 10 km from the base station in urban areas.

No hubs. To build ASKUE from iotCentr you do not need extra equipment . The meter transmits readings and receives commands from the USPD wirelessly, adders, hubs and whether repeaters.

Easy to install. Any electrician can install FOBOS 3.

Non-volatile memory I t. The safety of evidence does not depend onsupply power to Memory device.

Built-in battery. In the event of a power outage electricity, the device will continue to work autonomously.

Notification of emergency situations and accidents. In case of unauthorized use, use of magnets, opening and hacking, as well as power failures, “FOBOS 3” signals such events in your personal account.

Under development And produced in Russia. Support and development of LPWAN technologyfor ASKUE is carried out domestic team of engineers.
