Gang electric - HXGN15-12 (F.R) ring network cabinet

Product overview
HXGN15 a 12 (f. R) ring switchgear (hereinafter referred to as "ring network cabinet"), is needed for urban power grid renovation and construction and production of new type of high voltage switch cabinet.In the power supply system as well as the breaking load current and short circuit current and close short circuit current, is fit for ac 3 0 ~ 1 kv / 50 hz power distribution system.Widely used in urban construction and retrofit engineering, industrial and mining enterprises, high-rise buildings and public facilities, etc., as a ring net power supply unit and terminal equipment, play a power distribution, control and the protection of electric equipment, can also be used in a preloaded substation.The ring network cabinet with vacuum load switch, spring operating mechanism, the institution can be manual, electric operation.Grounding switch and isolating switch with hand operating mechanism, this ring network cabinet complete sex strong, small volume, no combustion and explosion danger, has reliable "five prevention" function.The ring network cabinet meet GB3906 "3 ~ 35 kv ac metal-enclosed switchgear", lEC60420 "electrical high voltage load switch a fuse combination" the relevant provisions of the standard.

The main technical parameters

Ring network power supply principle

Ring network power supply is composed of three basic units like {see figure 1) into the cabinet as ring network unit.When ren lines appear enzyme barrier, timely isolation.And by the other units to ensure the user become jade branch continuous power supply.Users back to the vessel network cabinet for transformer protection and isolation effect, ease of maintenance.
Ring network cabinet can be arbitrary extension, and can be combined according to user requirements made a variety of basic unit party village.
