A kind of high-tension switch cabinet
Technical field
The invention belongs to high pressure complete sets of electric switchgears and control devices equipment, be specifically related to a kind of high-tension switch cabinet.
Background technology
High-tension switch cabinet is a kind of switchgear assembly and control appliance. it is as power center (PC) and main switching compound.Main control, supervision, measuring and protection with doing power circuit, main power consumption equipment.Being normally placed in transformer station, switchgear house etc. locates.Electric elements mainly contain electric elements (major loop equipment) and secondary component (claim again secondary device or auxiliary equipment, refer to the low-voltage equipment that primary equipment is supervised, controls, measures, adjusted and protects) in the cabinet.
Present domestic have part switchgear house or transformer station, what originally use is the old-fashioned high-tension switch cabinet that overhauls from front cabinet door, several at least, tens high-tension switch cabinets are side by side closely in abutting connection with being set together at most, high-tension switch cabinet body is installed with cable and cable joint by wall thirty years of age on its body of wall or the floor.In transformation process of today, need to change old high-tension switch cabinet into new-type high-tension switch cabinet, so for this special switchgear house and transformer station, be faced with several difficult problems: cable and cable joint that (1) is retained on body of wall or the floor can also use, but its limited length, the high-tension switch cabinet that causes newly changing can only be installed on the old position, namely can only lean on wall thirty years of age; If cable and the cable joint left over are all changed, can need not to lean on wall so that newly change high-voltage switch gear, but because cable can not be continuous from indirect, can only integral body change, so will be a very large expense; Four sealing chambers about before and after the structure of the high-tension switch cabinet that (2) newly changes generally comprises at least, even more, for in front each chamber, can overhaul by opening the cabinet door, for upper chamber, rear portion (by wall one side), can overhaul by opening cabinet top reservation access door or plate, but for chamber under the rear portion, because the cabinet rear has body of wall to hinder, other high-tension switch cabinets that the cabinet left and right sides has again adjacency side by side to set up stop, so can't overhaul it.
