High-tension switch cabinet is will to be related to a kind of high voltage power distribution assembling of first and second complete sets of equipment assembling by certain connection plan, is used as restraining and protection electromotor, power transformer and high-tension line in power plant and transformer and distribution station.Wherein equipped with high-tension switch gear, protect electrical equipment, inspection measures instrument and bus, insulator etc..High-tension switch cabinet has fixed and handcart-type two big class, and typically in the transformer and distribution station of middle-size and small-size factory, number all adopts more economical fixed high-pressure cabinet greatly absolutely.The unique distinction of handcart switch cabinet is：When the equipment such as primary cut-out are installed in can pulling out on the handcart of propulsion, when equipment inspection is repaired, pull out or push similar handcart between appointing, just can restore electricity, possess and check the convenient and safety of repairing, and be substantially shorter the advantage of disconnected power off time, but price is high.
Usually the situation of operator's maloperation in the case of powered in application in existing high-tension switch cabinet, and this not only easily causes device damage, and there is potential safety hazard.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, provide a kind of high-tension switch cabinet electriferous state indicating module, its application when can indicate whether high-tension switch cabinet is in electriferous state, and then be avoided that operator in the case of powered maloperation and there is potential safety hazard.
The present invention solves the above problems and is achieved through the following technical solutions：High-tension switch cabinet electriferous state indicating module, including electrification in high voltage primary equipment, the first induction plate, the second induction plate, commutator, the first electric capacity, the first diode, first resistor, one-way SCR, the first stabilivolt and light emitting diode, described commutator is provided with two inputs and two outfans, described first induction plate and the second induction plate are connected with two inputs of commutator respectively, and described electrification in high voltage primary equipment is connected with the first induction plate；Described first electric capacity two ends are connected with two outfans of commutator respectively, the input/output terminal of described first diode is connected with the outfan of commutator and the input of one-way SCR respectively, it is connected with another outfan of commutator after one-way SCR outfan concatenation light emitting diode, described first resistor two ends are connected with the input of one-way SCR and the outfan of the first stabilivolt respectively, and the input of the first stabilivolt is connected with the control end of one-way SCR.
The working power of the present invention is to couple to obtain by way of electromagnetic induction, and according to Faraday law of electromagnetic induction, using the structure similar to transformator, electrification in high voltage primary equipment draws the secondary windings that the second induction plate is constituted with secondary first induction plate（Secondary）Between electric energy（Power）Coupling, to carry out power transmission, produces induction electromotive force similar in closed-loop path or coil, as long as conductor circuit is in the magnetic field of alternation, will produce induction electromotive force and faradic current.
Further, described commutator adopts bridge rectifier.
In sum, the invention has the advantages that：Overall structure of the present invention is simple, facilitate implementation, low cost, the present invention is after the energising of electrification in high voltage primary equipment, high-voltage signal sequentially passes through rectifier rectification and one-way SCR and adjusts and controls backward light emitting diode to convey intermittant voltage, and in light emitting diode, light emitting diode, according to the intermittant voltage obtaining by the frequency scintillation specifying, and then can indicate electriferous state, so, be avoided that operator in the case of powered maloperation and there is potential safety hazard.
