The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of warning isolating switch that can send position indicative signal.
For achieving the above object, the utility model provides following technical scheme: a kind of warning isolating switch, comprise isolating switch body, switch stator and push pedal, described isolating switch body is provided with switch stator and push pedal, described switch stator is provided with the groove that coordinates with the push pedal latch, and described push pedal and switch stator consist of switching device, are provided with central signal device in described groove, for electrically connecting, described series connection electrical equipment comprises the shunt opening device to described switch stator with the electrical equipment of connecting.
By adopting technique scheme, separate when being in normally off with push pedal when the switch stator, by being arranged on the central signal device in the switch stator, the switch stator will be to position indicative signal of shunt opening device, and by the shunt opening device action, making the automatic disconnection of series connection electrical equipment, load end cuts off automatically, make when opening isolating switch more safe and reliablely, avoid the person and the generation of equipment breakdown.
The utility model further is set to: described series connection electrical equipment is circuit breaker, is provided with the shunt opening device in described circuit breaker.
By adopting technique scheme, when switch stator and push pedal were in normally open, the shunt opening device in the circuit breaker that electrically connects with isolating switch also was failure to actuate, circuit breaker energy normally closed; Separate with push pedal when the switch stator when being in normally off, the switch stator can be to position indicative signal of shunt opening device, and the shunt opening device action makes the circuit breaker automatic disconnection, and is more safe and reliable when opening isolating switch.
The utility model further is set to: described switch stator with circuit breaker for connecting.
By adopting technique scheme, the switch stator is connected with circuit breaker and is equivalent to isolating switch and connects with circuit breaker, when the switch stator separates with push pedal, cause central signal device, by the switch stator, position indicative signal is sent to the shunt opening device, the shunt opening device action, make circuit breaker disconnect, load end cuts off automatically, due to isolating switch with circuit breaker for connecting, isolating switch also just disconnects voluntarily, avoids the generation of the person and equipment breakdown.
The utility model further is set to: being shaped as of described groove is square.
By adopting technique scheme, being shaped as of groove is square, facilitates push pedal and switch stator to carry out latch and coordinates, and the groove in push pedal enters the switch stator is when both are in normally open; When push pedal and switch divided stator from the time be in normally off.
The utlity model has following advantage: can send position indicative signal and play the function of automatic shutoff circuit, safe and reliable, avoid the generation of the person and equipment breakdown.
