Description
Technical field
The utility model relates to a kind of double power supply automatic switching switch and big lid thereof.
Background technology
At present, double power supply automatic transfer switch is very general in daily life, and known double power supply automatic transfer switch is made up of the circuit breaker of two band annexes, transmission mechanism and controller three parts that a cover is controlled by motor handle dual mode.In when work, by two circuit breakers to normal, be equipped with the two-way power supply and switch, and guarantee to have a circuit breaker to be in "on" position, important events are constantly powered being used for.The switch knob of common double power supply automatic switching switch is directly to be fixed on the shell, and when manually overhauling, switch can automatically reset, and can cause the generation of security incident, has potential safety hazard, lacks indicator light simultaneously and has brought inconvenience to use.
Summary of the invention
The utility model be for the switch knob that overcomes double power supply automatic switching switch common in the prior art be directly to be fixed on the shell, when manually overhauling, switch can automatically reset, can cause the generation of security incident, the deficiency that has potential safety hazard provides a kind of double power supply automatic switching switch and big lid thereof, and switch knob is detachable, the coefficient of safety height, the convenient use.
To achieve these goals, the utility model is by the following technical solutions:
The big lid of a kind of double power supply automatic switching switch of the utility model, comprise lid, be provided with groove at described lid upper surface, in described groove, be provided with sliding shoe, be provided with the handle connecting hole above described groove, be provided with slurry shape catch in described lid, an end of described slurry shape catch links to each other with sliding shoe by securing member, sliding shoe horizontally slips on groove and can drive slurry shape catch and selectively make the sealing of handle connecting hole and open, and is provided with the plurality of indicator lamps through hole at described lid upper surface.In lid, be provided with slurry shape catch, can realize the handle connecting hole is sealed and opens by moving slurry shape catch.The lid upper surface is provided with groove, and groove is provided with sliding shoe, and an end of slurry shape catch links to each other with sliding shoe by screw, starches the shape catch and moves sealing and the unlatching of realization to the handle connecting hole thereby sliding shoe horizontally slips can drive on groove.
As preferably, the number of described indicator light through hole is 4.
A kind of double power supply automatic switching switch, comprise circuit breaker commonly used, back-up breaker, sensitive switch, the transmission mechanism and the dismountable switch knob that connect circuit breaker commonly used and back-up breaker, described transmission mechanism outer cover is equipped with the big lid of double power supply automatic switching switch, is provided with indicator light in the indicator light through hole of the big lid of described double power supply automatic switching switch.In lid, be provided with slurry shape catch, can realize the handle connecting hole is sealed and opens by moving slurry shape catch.The lid upper surface is provided with groove, and groove is provided with sliding shoe, and an end of slurry shape catch links to each other with sliding shoe by screw, starches the shape catch and moves sealing and the unlatching of realization to the handle connecting hole thereby sliding shoe horizontally slips can drive on groove.When manually overhauling, mobile sliding shoe makes slurry shape catch that the handle connecting hole is opened, and can decontrol the sensitive switch sheet that props up simultaneously, sensitive switch spreads out of a signal, avoids switch to automatically reset, and prevents the generation of accident, just switch knob can be plugged, keep in repair.Be provided with indicator light in the indicator light through hole of the big lid of double power supply automatic switching switch, make the user come into plain view, person more convenient to use uses.As optimum, the number of indicator light is 4, be respectively first indicator light, second indicator light, the 3rd indicator light, the 4th indicator light, when duplicate supply power supply commonly used had electricity, first indicator light can be bright, when the duplicate supply stand-by power supply has electricity, second indicator light can be bright, and when duplicate supply power supply commonly used was in "on" position, the 3rd indicator light can be bright, when the duplicate supply stand-by power supply is in "on" position, the 4th indicator light can be bright.
As preferably, described indicator light is a light-emitting diode.Adopt light-emitting diode color rendering index height, color rendering is good, simultaneously than common lamp holder long service life.
Therefore, the utlity model has following beneficial effect: switch knob adopts detachable the setting, when manually overhauling, avoids switch to automatically reset, and prevents the generation of accident, has set up indicator light simultaneously, makes the user come into plain view and conveniently uses.
