SOPT series operating DC voltage system based on auot series operating current control switch

SOPT-1 series operating DC voltage system based on auot series operating current control switch.

Purpose:

Power supply to direct-current electrical receivers (electrical loads) and charge of accumulator batteries.

Range of application:

Organization of operating DC voltage system on low-power electric power stations (up to 10 kV) and substations of 35-220 kV, where the load of operating-current consumers is up to 40 A, and up to 250 A within short time (no longer than 10 minutes under peak load).

SOPT-1 consists of the following:

1. operating current control switch AUOT;
2. distribution cabinet ShR-05;
3. cabinet with accumulator batteries.

The AUOT series operating current control switch represents a microprocessor-based cabinet of unilateral maintenance.

The distribution cabinet ShR is used to distribute load and is completed with automatic circuit breakers manufactured by leading international producers (including Schneider Electric).

Features:

1. Availability of input and output circuits for overvoltage protection;
2. Split monitoring of accumulator battery (AB) current and load;
3. Improved thermal conditions;
4. Monitoring of AB circuit availability;
5. Electromagnetic interference output and input filters;
6. Availability of the fans controlled in terms of speed;
7. Adjustment of charging rate and recharge voltage depending of the temperature of the accumulator battery;
8. Operation in concurrency mode;
9. ModBusRTU protocol support with an upper-level supervisory system through RS-485 channel;
10. Remote start;
11. USB interfaces for on-line update of the software in the converters.

Range of application:

Organization of operating dc voltage system on electric power stations and substations of 35 kV and over (with high capacity), where the load of over 40 A (and peak loads of over 250 A) is needed for operating-current consumers.

SOPT-2 consists of the following:

1. charging-recharging voltage converter of PNZP series;
2. direct-current board SchPT;
3. accumulator rack;
4. OPzS and OGI series accumulator batteries, etc.

Features:

2. Availability of output circuits for overvoltage protection (in PNZP-M series charging-recharging voltage converters with present integrated protection unit of BKZ type).
3. Adjustment of charging rate and recharge voltage depending of the temperature of the accumulator battery.
4. The accumulator batteries are charged by various methods in accordance with manufacturer’s requirements.
5. Operation in the master-slave mode at which two chargers are connected to one load and one of those is working, while the other is in hot standby.
6. Operation of PNZP in concurrency mode.
7. ModBusRTU protocol support with an upper-level supervisory system through RS-485 channel.
8. Split monitoring of accumulator battery (AB) current and load (in PNZP series transducers – М2 (3)).
9. Improved thermal conditions (in PNZP series transducers – М2 (3)).
10. Monitoring of AB circuit availability (in PNZP series transducers – М2 (3)).
11. Electromagnetic interference output and input filters (in PNZP series transducers – М2 (3)).
