Abstract
The utility model discloses a switch cabinet anti-with grounding switch operation device comprising a cabinet body, a panel and a grounding cutter shaft arranged in the cabinet body; the panel is provided with a relay operation hole and a blocking apparatus thereof; the blocking apparatus is provided with a movable plate having a through hole; the movable plate is linked with the grounding cutter shaft through a transmission stay line. When the ground switch is closed, the grounding cutter shaft rotates and drives a pull head to move, meanwhile, the transmission stay line pulls the movable plate to one side, so the movable plate can block the relay operation hole on the panel, thereby preventing a handcart operation handle from inserting in the operation hole, and effectively preventing power accident generated by operation personnel to mis-operate the relay under a grounding switch separating state. When the grounding switch is separated, the grounding cutter shaft turns back, the movable plate returns to a relative position between the through hole and the relay operation hole under the effect of a return spring, so other operations are not affected, and usage is convenient.
Description
Technical field
The utility model belongs to high-tension switch cabinet and prevents misoperation apparatus technical field, the device that especially a kind of earthed switch that prevents switch cubicle operates circuit breaker when "on" position.
Background technology
What high-tension switch cabinet was widely used in power plant, industrial and mineral enterprises and institutions distribution and electric industry secondary system electric substation is subject to electricity, power transmission.According to the anti-requirement of high-voltage switch gear five, when earthed switch is during in "on" position, circuit breaker cart must not enter service position.For meeting this requirement, existing switch cubicle is all provided with guide rail interlock, is provided with the ligule backing pin with earthing interlock on circuit breaker cart guide rail, when earthing is during in closing position, backing pin stretches out guide rail and stops advancing of circuit breaker cart, to avoid it to enter service position.Existing this interlock exists the defect of easy generation misoperation, because advancing of circuit breaker cart is screw rod propulsion mode, during use, action bars shakes screw rod after inserting via handle hole on panel and advances; Because the backing pin of guide rail interlock is positioned at guide rail back segment, circuit breaker cart is heavier, and while advancing, inertia is large; Although backing pin is in stretching out state when earthing closes a floodgate, switch cubicle is through using for many years, and when operating personnel shake into speed, circuit breaker cart can be easy to back down backing pin and enter into mistakenly service position.Existing switch cubicle of while, the handle hole on its panel is open, operating personnel are easy to shake circuit breaker cart because of misoperation, cause the serious accident of power supply of operating breaker in the charged situation of switch cabinet outlet end.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of anti-band grounding switch operating device of switch cubicle that prevents that switch cubicle from operating circuit breaker when earthed switch closes a floodgate.
For solving the problems of the technologies described above, the utility model comprises cabinet, panel and is located at the ground connection cutter shaft in cabinet, described panel is provided with breaker operator hole, its design feature is the plugging device that panel is provided with breaker operator hole, ground connection cutter shaft is provided with and can, with the pull head of its rotation, be provided with transmission bracing wire between pull head and plugging device; Described plugging device comprises portable plate, guide rail and back-moving spring, and guide rail and panel are fastenedly connected, and portable plate is connected in guide rail and with it and slides and join, and the two ends of back-moving spring are connected with portable plate with panel respectively, and the other end of portable plate is connected with transmission bracing wire; Portable plate is provided with open-work, and when ground connection cutter shaft rotates, portable plate can slide along guide rail under the effect of transmission bracing wire, and after the revolution of ground connection cutter shaft, portable plate can be repositioned to the position that open-work is relative with breaker operator hole under the effect of back-moving spring.
Preferably described pull head is cam bit with bayonet, and transmission bracing wire is software brake cable, and brake cable sleeve pipe is fixed on cabinet and panel, and brake cable two ends are flexibly connected with pull head and portable plate respectively.
Further preferably described portable plate is provided with spacing dop, is also provided with the perspective mouth that bore is less than breaker operator hole on portable plate, in perspective mouth is provided with, looks peephole.
The beneficial effects of the utility model are: panel of the present utility model is provided with breaker operator hole plugging device, and plugging device is provided with the portable plate with open-work, and portable plate links by transmission bracing wire and ground connection cutter shaft.When earthed switch closes a floodgate, ground connection cutter shaft rotates and drives pull head to move together, now transmission bracing wire is moving to a layback by portable plate, make it block the breaker operator hole on panel, prevent handcart operating grip update hole, can effectively prevent operating personnel's misoperation circuit breaker under the state of grounding switch tripping, avoid the generation of electric power accident.During grounding switch tripping, the revolution of ground connection cutter shaft, portable plate is returned to the position that open-work is relative with breaker operator hole under the effect of back-moving spring, does not affect other operation, easy to use.
