HXGN-12 Fixed Box-type metal-enclosed switchgear (the ring counter) for the exchange of 50Hz, 10kV network as a load and short-circuit breaking and closing with short-circuit current. The ring counter in hand with electricity, the electric load of the spring body to operate switch, power switch and then switch with manual operation with agencies.

■ technical requirements
ZFN □ -10/630 with vacuum load switch ring network should be able to meet the counter ZFN □ -10/630 switch vacuum load all the appropriate technical requirements.

■ the structure and working principle
The ring counter air dielectric is mainly fitted with a vacuum load switch ZFN □ -10/630, the main program into the line of cabinets and counters, such as round.
□ counters into the program line
Inside the main loop there is a ZFN □ -10/630 vacuum load switch, with its isolation with a knife, as appropriate, also fitted with a knife consisting of ground, three were in a rack, and interlock each other. Therefore can be connected to bus, isolation, grounding of the three-stage operation, a drawer can be fitted with flexible CT, PT and other components.
□ round program counter
Inside the main loop there is a ZFN □ -10/630 vacuum load switch and fuse with the impactor (with isolation switch) and composed of ground knife, but also the realization of three-stage operation. Can also be mounted inside a flexible allocation of CT / PT and ZN 0 arrester and other components, it is sometimes counter measures can be omitted. Jin, round counter equipped with interlock switches and grounding protection bulkhead insulation, inside the switch and the doors and partitions between the mechanical interlocking, and to the "Five Anti" the requirements of the degree of enclosure cabinets IP2X.
