Three, summary of the invention:
The purpose of this utility model is to provide the control circuit of high-voltage circuit breaker of band locking link; the control circuit of high-voltage circuit breaker of this band locking link can realize reliable locking; when the contour pressure device fails of high-tension switch cabinet, protective device action; after primary cut-out tripping operation; check in the fault existed high voltage electric equipments such as high-tension switch cabinets, process well; after manual unlocking function; send remote control reclosing command by pressing starting button SB1 or a distant place on the spot, closing operation is carried out to primary cut-out.
The utility model solves the technical scheme that its technical problem adopts: the control positive source of the control circuit of high-voltage circuit breaker of this band locking link accesses the C13 contact of protection supervisory equipment after controlling mains switch KK1, scene and remote operation diverter switch SA, on-the-spot starting button SB1, the spacing contact Q series connection of circuit breaker chassis; Control positive source through controlling to access after mains switch KK1, on-the-spot stop button SB2 connect the D10 contact of protection supervisory equipment; Control C11, C12 contact that power cathode accesses protection supervisory equipment after controlling mains switch KK2, closing coil YC, primary cut-out normally closed auxiliary contact QF series connection; Control power cathode and often open through control mains switch KK2, breaking coil YT, primary cut-out the C15 contact accessing protection supervisory equipment after auxiliary contact QF connects; Control positive source access through controlling mains switch KK1 protection supervisory equipment C10 contact, control power cathode accesses protection supervisory equipment C18 contact through controlling mains switch KK2 and form electric power loop; Control power cathode accesses protection supervisory equipment D1 contact formation signal circuit through controlling mains switch KK2; Be connected to after trip signal relay normally open contact KST, closing locking relay coil KFC series connection and control mains switch KK1 and control between mains switch KK2; After unlocking button SB3 connects with closing locking relay normally open contact KFC, open union is at trip signal relay normally open contact KST two ends; Closing locking relay another control mains switch KK1 to being connected to after normally opened contact KFC, indicator light HL series connection and controlling between mains switch KK2, form closing locking instruction loop.
Beneficial effect:
The utility model does not have locking link for control circuit of high-voltage circuit breaker; in the contour pressure device fails of high-tension switch cabinet, protective device action; after primary cut-out tripping operation; when not carrying out any check processing to high voltage electric equipments such as high-tension switch cabinets; still can carry out closing operation to circuit breaker, very easily cause second accident or cause the potential safety hazard of fault spread.By increasing locking link in control circuit of high-voltage circuit breaker, only check in the fault existed high voltage electric equipments such as high-tension switch cabinets, process well, after manual unlocking function, closing operation could be carried out to primary cut-out, effectively prevent after the contour pressure device fails of high-tension switch cabinet, when not carrying out any check processing to high voltage electric equipments such as high-tension switch cabinets, closing operation is carried out to circuit breaker and the second accident caused or the fault spread caused.
