Abstract
The invention relates to a grounding wire hook of a transformer substation, in particular to an inductive anti-misoperation grounding wire hook. The inductive anti-misoperation grounding wire hook comprises a grounding wire hook body and is characterized in that an induction device is fixed on the grounding wire hook body and comprises a single chip microcomputer written with a distance comparison program, wherein the output end of the single chip microcomputer is connected with an alarm apparatus, the input end of the single chip microcomputer is connected with a distance measuring sensor, the power supply end of the single chip microcomputer is connected with the power supply end of the distance measuring sensor and connected with the output end of a storage battery through a normally-opened contact of an intermediate relay, and a coil of the intermediate relay is connected with the output end of an electromagnetic sensor. The inductive anti-misoperation grounding wire hook can sense whether a lead wire of a device required to be grounded is electrified or not and further reminds an operating person to perform device power outage and grounding wire arrangement, and the problem that the operating person of the transformer substation easily performs electrified grounding wire arrangement is solved.
Description
Technical field
The present invention relates to the earth connection hook of transformer station, be specially the fool proof earth connection hook of induction type.
Background technology
The operations staff of transformer station will be hooked on earth connection on the wire of substation equipment in grid switching operation process, make equipment ground, during normal running, want the equipment of the ground connection ground connection that will have a power failure, but because a variety of causes often causes operations staff's live earth connection, cause misoperation, and then bring harm to operations staff and equipment, and in transformer station's misoperation fault over the years, the accident of on-the-spot live earth connection accounts for very large ratio, in transformer station, need to stop the generation of this type of accident.
Summary of the invention
Easily there is the problem of the accident of live earth connection in the present invention, provides induction type fool proof earth connection hook in order to solve the operations staff of transformer station.
The present invention adopts following technical scheme to realize: the fool proof earth connection hook of induction type, comprise earth connection hook body, on earth connection hook body, be fixed with induction installation, in induction installation, comprise inner with the single-chip microcomputer apart from comparison program, the output of single-chip microcomputer is connected with alarm, the input of single-chip microcomputer is connected with distance measuring sensor, the power end of single-chip microcomputer is connected with the power end of distance measuring sensor, and by the normally opened contact of auxiliary relay and the output of storage battery, be connected, the coil of auxiliary relay is connected with the output of electromagnetic inductor.
The distance comparison program writing in single-chip microcomputer is those skilled in the art's well-known routines, the live wire of equipment can puncture ambient air in addition, in the time of in earth connection is hooked in breakdown region, being just equivalent to earth connection hook contacts with live wire, so, this effect apart from comparison program is the distance that distance measuring sensor is recorded and the secure threshold comparison of setting in it, guarantee that operations staff is outside the air breakdown scope of live wire, and then play and prevent that operations staff from the effect of misoperation occurring.
During live wire on the nearly equipment of this earth connection clasp joint, electromagnetic inductor in induction installation on earth connection hook makes the coil of auxiliary relay charged after sensing electromagnetic wave, the normally opened contact of auxiliary relay is closed, storage battery is to distance measuring sensor and single-chip microcomputer power supply, distance measuring sensor is measured the distance between earth connection hook and live wire, then be transported in single-chip microcomputer, single-chip microcomputer is by the distance recording with apart from the secure threshold comparison of setting in comparison program, when the distance recording is less than secure threshold, Single-chip Controlling alarm equipment alarm, the operation of reminding operations staff to stop installing earth connection.
Whether the fool proof earth connection hook of induction type provided by the invention can induce the wire of the equipment that needs ground connection charged, and then the operation of reminding operations staff to stop installing earth connection, easily there is the problem of the accident of live earth connection in the operations staff who has solved transformer station.
