1 General information

1.1 Cabinets (panels*) of ПСН1200 type and derived boards (DCB) are applied for provision of power supply from rectifiers or accumulator batteries of direct current service consumers, control circuits and alarm system of substations with voltage of up to 500 kV for the facilities under construction and under reconstruction or for replacement of old or broken panels of ПСН1200 series.

1.2 ПСН1200 cabinets of ElKor Corporation are manufactured for operation with two rectifiers and either with one or two accumulator batteries (АB) with the elements number (n) in the battery equal to 108 or more than 108.

1.3 Structurally cabinets are the closed metallic structures with the devices installed inside and the accomplished electric connections. Cabinets’ maintenance is one-sided; from the maintenance side there is a double-wing door. Cabinets make it possible to install them on the cable channel or in apertures, cables lead-in is from the down side.

Overall dimensions of cabinets (height х length х depth) for the replacement of broken or old ones are 2200 mm х 900 mm х 800 mm, overall dimensions of the boards consisting of ПСН 1200 cabinets for the replacement correspond to the dimensions of those replaced on condition of preservation of the existing cable network. In this case as well as during the design of new facilities board overall dimensions are to be agreed when ordering.

Cabinet weight is no more than 300 kg.

1.4 Voltage of main and auxiliary circuits is 220 V of direct current, main circuit current is 160 А, 250 А, 315 А, 400 А, 630 А, electrodynamic stability is no less than 10 kA, thermal stability is up to 100 kA2 s.

1.5 According to functional designation ПСН 1200 cabinets of ElKor are divided into:

а)  lead-in from rectifiers and from one AB with n = 108 elements with sectional connection of:

  1. main buses;
  2. control buses;
  3. alarm buses.

Standard performance ПСН1201-ЭК;


b) lead-in from rectifiers and from one AB with n > 108 elements with sectional connection of:

  1. main buses;
  2. control buses;
  3. alarm buses.

Standard performance ПСН1202-ЭК;


c) outgoing circuits from buses within power supply from rectifiers or AB with n = 108 elements with electric power unit of emergency lightning.

Standard performance ПСН 1203 -ЭК;


d) outgoing circuits from buses within power supply from rectifiers or AB with n = 108 elements without electric power unit of emergency lightning.

Standard performance ПСН 1203.1 -ЭК;


e) outgoing circuits from buses within power supply from rectifiers or AB with n > 108 elements with emergency lightning unit.

Standard performance ПСН1204-ЭК;


f) outgoing circuits from buses within power supply from rectifiers or AB with n > 108 elements without emergency lightning unit.

Standard performance ПСН1204.1-ЭК;


g) lead-in from rectifiers and from two AB with n = 108 elements with sectional connection of:

  1. main buses;
  2. control buses;
  3. alarm buses.

Standard performance ПСН1205-ЭК;


h) lead-in from rectifiers and from two AB with n > 108 elements with sectional connection of:

  1. main buses;
  2. control buses;
  3. alarm buses.

Standard performance ПСН1206-ЭК.


1.6 In accordance with functional designation ПСН1200-ЭК cabinets generally provide: - reception of power energy from rectifiers and from one or two accumulator batteries with the number of elements equal to 108 or more than 108 elements:


- charge and discharge of accumulator battery;
- power supply of main buses;
- power supply of control buses;
- power supply of alarm buses;
- distribution of power energy among consumers;
- protection of power source and outgoing circuits from the short-circuit currents and overloads;
- measurement of pole insulation in respect of the ground;
-measurement of basic parameters and necessary alarm system.

1.7 Single-line schemes of main circuits of ПСН1200-ЭК cabinets are provided in table 1.

1.8 Possible variants of element base of ПСН1200-ЭК cabinets’ construction are provided in table 1.
