Abstract
The invention discloses a device for preventing operation of a grounding switch of a switch cabinet. The device comprises a cabinet body, a panel and a grounding knife shaft arranged in the cabinet body, wherein a circuit breaker operating hole and a sealing device thereof are arranged on the panel, a movable plate provided with a through hole is arranged on the sealing device, and the movable plate is linked with the grounding knife shaft through a transmission guy cable. When the grounding switch is switched on, the grounding knife shaft rotates and drives a pull head to move together, at that time, the transmission guy cable pulls the movable plate towards one side to block the circuit breaker operating hole on the panel so as to prevent a handcart operating handle from being inserted into the operating hole to effectively prevent an operator from operating the circuit breaker by mistake at the switching off state of the grounding switch to avoid electrical accidents. When the grounding switch is switched off, the grounding knife shaft rotates, the movable plate resets to a position where the through hole is opposite to the circuit breaker operating hole under the action of an offsetting spring without affecting other operations, so that the application is convenient.
Description
Technical field
The invention belongs to high-tension switch cabinet and prevent the misoperation apparatus technical field, the device that especially a kind of earthed switch that prevents switch cubicle is operated 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, during in "on" position, circuit breaker cart must not enter service position.For meeting this requirement, existing switch cubicle all is provided with the guide rail interlock, is provided with the ligule backing pin with earthing interlock on the circuit breaker cart guide rail, when earthing during in closing position, backing pin stretches out guide rail and stops advancing of circuit breaker cart, to avoid it, enters service position.Existing this interlock exists the defect of easy generation misoperation, because advancing of circuit breaker cart is the screw rod propulsion mode, during use, action bars shakes screw rod after inserting via the handle hole on panel and advanced; Because the backing pin of guide rail interlock is positioned at the guide rail back segment, circuit breaker cart is heavier, and while advancing, inertia is large; Although when earthing closes a floodgate, backing pin is in stretching out state, 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.Have switch cubicle now, the handle hole on its panel is open simultaneously, and 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 problem to be solved in the present invention is to provide a kind of anti-band of switch cubicle grounding switch operating device that prevents that switch cubicle from being operated circuit breaker when earthed switch closes a floodgate.
For solving the problems of the technologies described above, the present invention includes cabinet, panel and be located at the ground connection cutter shaft in cabinet, described panel is provided with the breaker operator hole, its design feature is the plugging device that panel is provided with the breaker operator hole, the ground connection cutter shaft is provided with and can, with the pull head of its rotation, be provided with the 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 the transmission bracing wire; Portable plate is provided with open-work, and when the 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 the breaker operator hole under the effect of back-moving spring.
Preferably described pull head is cam bit with bayonet, and the transmission bracing wire is the software brake cable, and the brake cable sleeve pipe is fixed on cabinet and panel, and the brake cable two ends are flexibly connected with pull head and portable plate respectively.
Further preferably described portable plate is provided with spacing dop, also is provided with the perspective mouth that bore is less than the breaker operator hole on portable plate, in the perspective mouth is provided with, looks peephole.
Beneficial effect of the present invention is: panel of the present invention is provided with breaker operator hole plugging device, and plugging device is provided with the portable plate with open-work, and portable plate is by transmission bracing wire and the interlock of ground connection cutter shaft.When earthed switch closes a floodgate, the ground connection cutter shaft rotates and drives pull head and moves 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 the breaker operator hole under the effect of back-moving spring, does not affect other operation, easy to use.
