Embodiment
The exemplary embodiments embodying feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from the scope of the present invention, and explanation wherein and to be shown in be use when explain in essence, and be not used to limit the present invention.
As shown in Figure 1, one embodiment of the invention, a kind of high voltage electric shock-proof protector is provided, comprise: power supply box and the travel switch 3 be arranged in this power supply box and A.C. contactor 4, plug-in strip 6, earth leakage protective device 8 and insert row 7, power supply box comprises casing 1 and case lid 2, and case lid 2 is connected by hinge 5 with casing 1 one end; Between casing 1 and case lid 2, one end of hinge 5 is provided with back-moving spring; Plug-in strip 6 and insert row 7 are located at the both sides outside casing 1 respectively, and earth leakage protective device 8 is located in casing 1; Connected by power line 9 with between travel switch 3 and A.C. contactor 4, travel switch 3 is located on casing 1, near case lid 2 position, the contact on travel switch 3 is exposed to outside casing 1, and A.C. contactor 4 is opened and being communicated with and disconnection of the striking control power circuit of closed pair contact according to case lid 2.
Concrete; power line 9 is introduced by the end of incoming cables of plug-in strip 6; the power input of travel switch 3 is linked into by entrance hole 10; the power input of A.C. contactor 4 is linked into by the power output end of travel switch 3; the power input of earth leakage protective device 8 is linked into by the power output end of A.C. contactor 4; be connected by the power inlet of wire hole 11 with insert row 7, finally exported by insert row 7 power output end.
In high voltage test, experiment work member is by operating instrument personnel and test high-voltage connection composition of personnel, when carrying out high voltage test, this casing 1 is set to high-voltage connection wiring personnel special seat, after high-voltage connection personnel wiring, seat carries out power supply test on case lid 2, now, case lid 2 closes with casing 1, case lid 2 strikes the contact of travel switch 3, and the pleased travel switch 3 of casing 1 is connected, and exchanges the adhesive of electric shock device 4, and then experiment power supply circuit is communicated with, and then operating personnel can carry out power supply test to insert row 7 power output end be arranged on casing 1; After test completes, wiring personnel to leave case lid 2 go remove wiring time, back-moving spring 10 utilizes the tension force produced when case lid closes, case lid 2 is opened automatically, resets to off-position, and then the travel switch 3 in casing 1 disconnects, A.C. contactor 4 contact disconnects, cut off experiment power supply circuit, by testing equipment auto-breaking, effectively avoid and cut off the electricity supply because test operation personnel forget or there is the reason of electric leakage and the generation of personal injury accident that causes because of power source aging.
