Description

SF6-11kV/24kV/33kV Solid Insulated Switchgear / Ring Main Unit / RMU / Power Distribution Equipment

Overview of Solid Insulated Switchgear

Solid Insulated Switchgear.The SF6 insulated switchgear is suitable for middle voltage power distribution system with a rated voltage of 11kV and 40.5kV. It could be used as RMUs in a power supply network, fault isolating switches and sectionalizing switches.

If equipped with distribution automation devices (FTU/DTU) and communication devices, the SF6 insulated switchgear could communicate with the control center, measure the cable voltage, current, etc, and monitor the working status of

 SF6 gas insulated ring main unit(RMU/C-GIS):

Safe ring/plus RMR type SF6 gas insulated ring main unit is integrating with SF6 infill cabinet which gather with LBS, VCB, Fuse, ES, DS, etc.

By the perfect integration of stationary type and flexible expansion, RMR type SF6 gas-insulating compact close metal switchgear(Ring main unit) with the adoption of the modular design, is suitable for end-user or network node, meanwhile meets the requirement of all kinds of switching substations cabinet-type transformer substations and cable branch cabinets. It characters on its compact structure, safety and reliability, longevity and maintenance free.

This product is in conformity with the standards of IEC60420,

Product feature:

Panel structure: The panel body is enclosed by 2mm aluminium-zinc plated steel plate after multi-bending. It is simple, firm, delicate and peculiar.

1. Busbar compartment: The busbar compartment is located in the top and connect with neighhboring panel.
2. Load break switch is a separated unit with SF6 gas.
3. Cable compartment: Approximate 75% room of connecting cable and installing fuse, earthing switch and PT.
4. Mechanism chamber and interlock: The chamber consists of operating mechanism, mechanism interlock, position indicator, auxiliary contact trip coil, charge indicator and interlock.
5. LV chamber: It is lockted in the top. It mainly used for installing instrument, relay and motor.
6. Circuit breaker compartment: The circuit breaker (SF6 or Vacuum) is located below load break switch.

Pressure release:

A.Upper pressure release: It is mainly used for releasing gas pressure which produced by arc accident in busbar load break switch compartment.

B.Down pressure release: It is mainly used for ealeasing gas pressure which produced by arc accident in cable small compartment.
