KSO-216Т

Features

  • Fully prefabricated.
  • Small size.
  • Does not require maintenance
  • Shielded solid insulation with a grounded shield reduces the risk of internal arc, ensures safety and reliability, extends the life of the product
  • Front cable connection significantly reduces installation time and cost
  • Possible customization to fit non-standard layouts.

Design

KSO-216T cell is a prefabricated metal structure, one-side service, for internal installation. It consists of galvanized steel casing with metal partitions between the compartments. There are devices and fittings of the main and auxiliary circuits inside the case.

For safe maintenance and the failure localization, the enclosure is divided into isolated compartments:

- low-voltage (relay) compartment

- switching device and busbar compartment

- cable compartment.

LV (relay) compartment incorporates auxiliary circuit devices. Usually, there is an MPZ unit, measuring instruments, metering devices, control buttons, and light-signaling equipment on the compartment door.

The cell busbars are in rigid shielded insulation and do not have contact with the environment. The compartment is equipped with an overpressure relief valve that ensures the release of hot gas and arc combustion products into a safe for maintenance personnel place

Installed in the cell multifunctional switching module has three modifications:

- vacuum power switch combined with three-position disconnector-earthing switch

- vacuum load break switch combined with three-position disconnector-earthing switch

- three-position disconnector-earthing switch.

Cable compartment serves to accommodate and connect cables. Compartment is separated from the switching device and busbar by metal partition. Following equipment can be located inside: - current transformers

- voltage transformers

- zero-sequence current transformers

- surge arresters.

In case of short-circuit arc, the combustion products and gases from the cable compartment are discharged via the pressure relief valve located on the rear panel of the cell.

Cable compartment door is equipped with an interlock that does not allow to open the door with if the earthing switch is disconnected.

Interlock devices installed in the chamber and their quantity comply with the requirements of the Electrical Installations Code (EIC), 7th edition, and GOST 12.2.007.4.

LED lights are used for lighting of the cell housing interior.
