Mainly be to rely on the arc light detection system at arc protection at present, detect arc light after, the arc protection system provides front end circuit breaker trip signal, tripping front end circuit breaker is cut off the electricity supply, thereby extinguish arcs, the protection person and device security.The molar behavior time of this type of arc protection system wherein is about 1 ~ 10ms detection time, about circuit breaker 80 ~ 100ms operate time about 100ms at present.But produce the rule of destroying according to the electric power system arc light; arc light takes place can cause bigger destruction and injury to circuit, equipment and the person behind the 100ms; therefore traditional arc protection system is difficult to guarantee safety because growing partially its operate time, and further shortening the quenching time is trend of the times.
The utility model content
The purpose of this utility model provides a kind of arc light of quick action to protect integrated switch fast with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Arc light described in the utility model protects integrated switch to comprise input fast, output, driving governor, vacuum interrupter, the soft magnetism shell, driving shaft, the light-weight metal dish, permanent magnet, moving iron core, spring, separating brake repulsion coil and combined floodgate repulsion coil, the control input end of described driving governor is connected with the signal output part of arc light detecting unit, described input and described output are connected with inner with the outer end of the indoor switch of described vacuum extinction respectively, the stage casing of described driving shaft places in the described soft magnetism shell, the inner of the switch that one end of described driving shaft and described vacuum extinction are indoor is connected, described light-weight metal dish is fixedly connected on the other end and the concentric of described driving shaft, described separating brake repulsion coil and described combined floodgate repulsion coil are installed on the both sides of described light-weight metal dish respectively, described driving shaft passes the centre bore of described separating brake repulsion coil and described combined floodgate repulsion coil, the power input of the power input of described separating brake repulsion coil and described combined floodgate repulsion coil respectively with corresponding connection of power output end of described driving governor; Described permanent magnet is fixedly installed on the inwall of described soft magnetism shell, described moving iron core is loaded on the described driving shaft by its center borehole jack and is corresponding with described permanent magnet position, and described spring is installed on described moving iron core and the described driving shaft near between the boss of described vacuum interrupter one side.
In the course of work, electric current by driving governor control separating brake repulsion coil and combined floodgate repulsion coil has or not, thereby having or not of the repulsion that control separating brake repulsion coil and combined floodgate repulsion coil produce the light-weight metal dish, the moving driving axial of light-weight metal dribbling near or move away from the direction of vacuum interrupter, thereby realize the closed or disconnection of the switch that vacuum extinction is indoor, reach the control purpose.After the repulsion coil is realized the closed of switch or is disconnected, the repulsion coil blackout, magnetic force between moving iron core and the permanent magnet and the pressure of spring can keep driving shaft to remain static, and make the indoor switch of vacuum extinction keep original state and need not to allow repulsion coil consume electric power.
Further, also be connected with flexible conductor between the inner of the indoor switch of described output and described vacuum extinction.Flexible conductor can adapt to the mobility of switch the inner better.
As preferably, described light-weight metal dish is A3 steel disk, aluminium dish or copper dish.
The beneficial effects of the utility model are:
The utility model adopts vacuum interrupter, and arc light was exploded in indoor being difficult to of vacuum extinction, has strengthened security performance; Adopt repulsion coil and light-weight metal dish to constitute quick electromagnetic repulsion driving mechanism, it is swift in motion reliably, generally can finish dump at 10-20ms; Adopt permanent magnet, moving iron core and spring to constitute the on off state maintaining body, can reduce the energy loss of repulsion coil, energy savings.Generally speaking, the utlity model has that capacity of short circuit is big, quick action, inherently safe, reusable, cost is low, reliability is high, volume is little, easy for installation advantage.
