Dis Sub-12 Environmental protection gas switchgear

Dis Sub-12 Environmental protection gas switchgear

The problem of gas leakage and pollution can be solved by replacing sf6 with safe and environmentally friendly mixed gas in gas tank. It has high level of operation security and is used  as the core unit of distribution network. The equipment is mainly composed  of  modular  components  such  as  sealed  switching  gas  tank,  cable  chamber  base,  mechanical  room  and instrument room. Circuit breaker, load switch, three-station isolating switch, environment-friendly insulation bush and other core components are sealed in the gas tank. The structure is fully sealed and maintenance-free.
Vacuum  circuit  breaker  and  vacuum  load  switch  adopt  general  main  structure  design,  which  can  better  ensure  the consistency of switch body: closing and opening of main circuit, the spring mechanism is simple and reliable, the knob is adopted. And the three-station isolating grounding switch adopts mature knife gate structure, which has the characteristics of preventing the risk of  connection the in the main circuit with electricity.
It is safe to use, environmental friendly, intelligent designed, convenient to use, maintenance-free, and the whole cost is low.

Product Features

Maintance Free

Dry air, movable and fixed contacts, arc-extinguishing chamberand busbar are sealed in one gas box. Maintance-free life is 30years.

Full-Sealed And Insulated In-Out Cables

Adopting corresponding full-sealed and insulated cable connectors as the requirements of users. Electrified display functions can show status of each circuit exactly.

Modularized And Expansible

Combination of expansible modules, one box contain 5 modules maximally, and contain more modules through the extension of busbar.

Multiply Connection Schemes

As the requirement of users,adopting load switch,load switch+fusible cutout, or vacuum circuit breaker combinations to meet the needs of various incoming and feeder line circuit.

Visible Open Connects

Through the observation window on the panel, we can see the open connects of load switch or the positions of grounding switch.

Electric Operation, FTU

Adopting special voltage transformers to collect electricity, provide power supply for operating mechanism and ftu, and measure the signals of protective voltage. Install the special battery and charging modules to ensure the continuous power supply for operating power resource and ftu. Supporting ftu mechanism with corresponding functions according to the requirements of users.

Technical Parameter

 Note:1.The rated current of load switch+fuse combination depends on the fuse.      2.The rated short circuit breaking current limits by high voltage fuse
