Embodiment
Introducing the embodiment of a kind of switch of the utility model below in conjunction with accompanying drawing, but should be pointed out that embodiment of the present utility model is the preferred embodiment for task of explanation, is not the restriction to the utility model scope.
Referring to accompanying drawing 1, a kind of switch comprises a switch element 11 and is integrated in on-off controller 12 in same box body with described switch element.
The first port of described switch element 11 is connected with the master switch equipment 13 of outside, and the second port is connected with the electrical equipment 14 of outside, after master switch equipment 13 closures, can or disconnect by the closed of switch element 11, comes the opening and closing of control apparatus 14.Wherein, described switch element 11 can be the regular tap of routine.
Described on-off controller 12 is used for controlling described switch element 11 after outage, makes it recover off-state.Described on-off controller 12 comprises a rectification module 121, an energy-storage module 122 and a control module 123.
Described rectification module 121 is connected with electrical equipment 14 and the described energy-storage module 122 of outside respectively, and it is described energy-storage module 122 chargings that the AC power that is used for inputting is transformed to DC power supply.When described switch element 11 forms closed circuit with master switch equipment 13 and electrical equipment 14, a foreign current part described electrical equipment 14 of flowing through, for described electrical equipment provides electric energy, a part is through be that described energy-storage module 122 charges after described rectification module 121 rectifications.Wherein, described rectification module 121 can comprise at least one rectifier diode.
Described energy-storage module 122 is connected with the second port of described control module 123 and described switch element 11 respectively.When master switch equipment 13 disconnected, described switch element 11 was still closure state, and this moment, described energy-storage module 122 was described control module 123 power supplies, drove described control module 123 and disconnected described switch element 11.Wherein, described energy-storage module 122 can comprise at least one inductance element, described control module 123 can comprise at least one electromagnetic relay or electromagnet, and described inductance element provides electric energy for described electromagnetic relay, and electromagnetic relay produces magnetic attraction switch element 11 and disconnects.
Referring to accompanying drawing 2, the circuit connecting mode of a kind of switch of the utility model comprises switch S 1, electric light 21, I diode VD1, II diode VD2, inductance component L 1, electromagnetic relay E1, III diode VD3 and IV diode VD4.
Switch S 1 is conventional switch, controls the opening and closing of electric light 21.
I diode VD1 and II diode VD2 are serially connected in the two ends of inductance component L 1, and polarity is identical.Namely the negative pole of I diode VD1 is connected to an end of inductance component L 1, and the other end of inductance component L 1 is connected to the positive pole of II diode VD2.The external communication electric current changes direct current into after I diode VD1 rectification, direct current flows into inductance component L 1 and is its charging accumulation of energy, and flows to switch S 1 through II diode VD2.Can also be connected in series a resistive element R1 between described II diode VD2 and described inductance component L 1, be used for dividing potential drop, avoid inductance component L 1 with electric light 21 short circuits.
