In view of this, the inventor studies this, develops specially a kind of central-positioned high-voltage switch cabinet with electroscopic window, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of central-positioned high-voltage switch cabinet with electroscopic window, can significantly shorten the electrical verification time, and simple in structure, safe and reliable.
To achieve these goals, solution of the present utility model is:
A kind of central-positioned high-voltage switch cabinet with electroscopic window, rear lower cabinet door offers the rectangular through holes corresponding with cable joining seam in cable vault, form the electroscopic window entering for electroscope, and with the sealing of cover plate slidably, the upper and lower both sides of rectangular through holes are equipped with moving guide rail, slidably cover plate is arranged on above-mentioned moving guide rail, described guide rail and cover plate are all positioned at the inner side of rear lower cabinet door, do not destroy the former profile of high-tension switch cabinet, and it is strong to have explosion-proof ability, the feature that safe class is high; On described rear lower cabinet door, be further provided with electromagnetic lock, the lock core of electromagnetic lock contacts with cover plate, adopt the auxiliary contact access electromagnetic lock electric loop of switch cart, switch cart only could be opened electromagnetic lock in the time of test position, open cover plate, switch cart is equal locking electromagnetic lock in the time of all the other positions, cannot open cover plate.
As preferably, the outside of described cover plate is provided with handle, for movable cover plate.
Described cover plate adopts polymethyl methacrylate, and there is light weight, be convenient to mobile and observe, and the advantage such as protective, good insulating.
As preferably, above-mentioned rectangular through holes width is 4-6cm, and length is 10cm-30cm, and the size of cover plate is slightly larger than rectangular through holes.
Electric-magnetic lock power supply is connected with the anti-error power supply of high-tension switch cabinet, on power supply terminal row, get one pair of node as electric-magnetic lock ring current, by the test position contact access anti-misoperation locking secondary circuit of switch cart, in order to judge locking open condition, switch cart only could be opened barring condition in the time of test position, in service position, maintenance position and shake when shaking out process position all open lockings.Locked loop secondary cable line passes to relay control room together along circuit Current Transformer Secondary cable, forms error blocking proof circuit.Adopt electromagnetic lock, have ready-made anti-error power supply, to high-tension switch cabinet original structure, without destruction, improvement project amount is little; And secondary circuit is simple, easy care; Walkaround inspection is also convenient.
The electroscopic window that adopts said structure, electrical verification process simplification is: check that XX line is really in cold standby state 1.; 2. open electrical verification window, if can open, carry out step 3, if can not open, reexamine XX line really in cold standby state; 3. identify true no-voltage in XX line line side; 4. close electrical verification window and check; XX line close earthing switch blade and check.Whole electrical verification process does not need electricity check trolley to advance breaker chamber, only need can complete electrical verification step by electroscopic window with electroscope, has greatly simplified operating process, has shortened the operating time.And whole electroscopic window setting, without significantly changing high-tension switch cabinet, cost is low and safe and reliable.
