Features

  • Fully prefabricated.
  • Convenient maintenance
  •  Using spring-motor drive you can manually turn it on/off without engaging any additional devices when there is no auxiliary power.
  • Isolated low-voltage (relay) compartment
  • Possible customization to fit non-standard layouts.

 

Design

One-side service chamber is a metal structure made of 2 mm thick steel (bearing structures are 3 mm thick). All components are painted with powder paint.

To ensure the safety of the maintenance staff, the chamber is divided into three isolated compartments: busbar, high-voltage, and low-voltage (relay) compartments.

Support insulators with busbars and busbar breaker are installed in busbar compartment.

HV compartment contains main circuit equipment - vacuum breaker, current transformers, voltage transformers, fuses, line disconnector, and surge arresters.

Installed in the relay compartment are: relay protection and automation microprocessor units, control and metering devices.

The chamber has two doors. Upper door covers the relay compartment. The lower door covers high-voltage equipment.

Busbars are closed by protective housing on the front side.

There are inspection windows in the lower door and protective casing to see the inside of the chamber.

One-side service chambers have internal LED lighting.

Chambers provide for cable end cutting and accomodate the connection of up to four three-phase cables up to 240 mm², as well as six single-phase cables up to 500 mm² with plastic insulation.

Chambers are deparated from each other by metal dividers.

Chambers have several electrical and mechanical interlocks for safe operation.

In two-row arrangement in switchgear space, bus bridges are installed on the chambers.

Bus bridges are of two types - without disconnectors and with disconnectors for busbar sectioning. Switch actuators are placed on the panels 200 mm wide, mounted between the the two end chambers in the row.
