Product Description

HXGN_-12(SF6) Unit type AC metal-enclosed ring main unit is a new generation of high-pressure electric appliance product designed and developed independently by our own company according to the requirement of the domestic agricultural electricity and the city net transformation after introduction of overseas advanced technology.Each technical performance index completely reaches the IEC298 and GB3906 standard.
The loop-net cabinets main switch, the opereting mechanism and the components is made of the SFL-12/24 switch equipment importedoverseas and ass-embled at home. We can also installthe origimal piece of HADUS type SF acording to the request users. The circuit breakeror the VD4-S vacuum circuit breaker divide into two kinds: be operated manually and electrically according to the operating mode.

 

The cabinet body is riveted after processed by numerical control machine tool with reliable mechanical intertlocking and the misoperating prevention function. The protection grade reaches IP3x.
This product has the remarkable characteristics such as the small volume,light weight, artistic appearance, simple operation, long life, high parameter with no pollution and litle maintenance.

This ring network type cabinet makes air as the
insulating medium, mainly assembled with ZFN_-10/630 type vacuum load switch. And there are two cabinet schemes - incoming cabinet and outgoing cabinet.

1.Incoming cabinet scheme
There is a ZFN_-10/630 type vacuum load switch on the main circuit inside the cabinet with isolating knife, and grounding knife conditionally. The three of them are all installed in one machine stand and there are interlocks among them, so that it is realized to connect the operation of three working stations of bus, isolation and grounding. Inside the cabinet the components such as CT, PY are available.
2.Outgoing cabinet scheme
ZFN_10/630 type vacum load switch, fuse with striker (used as isolating switch) and grounding knife on the main circuit inside the cabinet, and the three working stations operation can be realized. Inside the cabinet the componets such as CT/PT and ZNO arrester are available, so the metering cabinet can be omitted. Inside the incoming cabinet and outgoing cabinet there is insulating protecting baffle interlocked wih grounding switch.And inside the cabinet, the mechanical interlocks are adopted between each switch and baffle as well as the cabinet door with the requirement of "five-prevention" and IP2X of the protection degree of the cabinet enclosure.
