Description
Automatic partitioning point (recloser) 6(10) kV
APS-6 (10) kV is designed to operate in overhead distribution networks of three-phase alternating current with a frequency of 50 Hz and a rated voltage of 6 or 10 kV and is used as a partitioning point, network redundancy to improve the reliability of power supply facilities.
The use of APS allows:
- to increase the reliability of the power supply of a separate feeder, since all emergency processes on the line behind the APS will be partitioned and will not affect the supply of other consumers;
- to perform remote (from the dispatcher's console) switching on/off of consumers via GPRS/GSM modem or USPD (data collection and transmission device);
- integrate into the current automated process control system as a lower-level subsystem. Transmission of data on the position of the switching device, to register information about emergency events on the line;
- perform the AVR function on a VL 6-10 kV
The composition of the switching module:
1 - current sensors (Rogovsky belt);
2 - voltage sensors;
3 - vacuum circuit breaker;
4 - external connection compartment.
Installation of APS-6(10) kV on overhead line supports
APS-6(10) kV, regardless of the execution of the overhead line power supply circuit, has a single-support and two-support design.
To install the APS-6(10) kV, supports with the following racks are used: SV-95, SV-105, SV-110.
Single-support version of APS-6(10) kV with two-way power supply
