Abstract
The utility model discloses an electroscope for a power transmission line. The electroscope comprises a contact electroscope with a buzzer; the head of the electroscope is provided with a magnet and is connected with an insulation rope; the other end of the insulation rope passes through the top of a long insulation rod, extends to the bottom of the long insulation rod, and is fixed on a roll at the bottom of the long insulation rod; the roll is connected with a winding and unwinding device which can drive the roll to rotate; and the long insulation rod is a telescopic rod. The electroscope is provided with the long insulation rod, the lower part of the long insulation rod is provided with the roll, the contact electroscope with the buzzer is provided with the insulation rope which passes through the long insulation rod, and the other end of the insulation rope can be fixed with the roll at the bottom of the long insulation rod, so an operator can pull the long telescopic insulation rod to the height of an electric wire on ground and directly detect whether voltage exists on the power transmission line without climbing to the top of a tower. The electroscope has a simple structure, facilitates measurement, and can be carried conveniently, effectively improve measurement working efficiency, and improve measurement safety.
Description
Technical field
The utility model relates to a kind of circuit checker, specifically relate to a kind of need be on transmission line of electricity the device of electrical verification before the attaching ground wire.
Background technology
According to " State Grid Corporation of China's electric power safety working regulation (circuit pack) " regulation, before dead line job site attaching ground wire, should first electrical verification, identify the true no-voltage of circuit.During electrical verification, should use relevant voltage grade, qualified contact electroscope.Common used electroscope all adopts La Lashi on the ultra-high-tension power transmission line at present, promptly according to the test voltage grade, corresponding contact electroscope is fixedly mounted on telescopic insulation stock head; Measure; During measurement, survey crew is gone up to the cross-arm of tower masthead portion earlier, and pulley is fixedly mounted on the cross-arm; Through insulating block electroscope and insulation stock are transported to cat head by the ground staff, measure.Whether this mode is measured transmission line of electricity has voltage to have following defective: carry inconvenience, when measuring, need carry pulley and wait aid with the insulation rope, survey crew at first will be with pulley and insulation rope to wait until cat head; Pulley is installed, is put down the insulation rope, cooperate will insulate stock and electroscope of personnel to be delivered to cat head through pulley by ground; Just can measure, accomplishing this measuring process needs two staff at least, and labour intensity is big; Time is long, and security is low.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of transmission line of electricity electroscope whether transmission line of electricity has voltage of just can measuring on ground is provided.
The purpose of the utility model is through this practicality of following technical scheme:
A kind of transmission line of electricity electroscope; Comprise the contact electroscope, said contact electroscope is the contact electroscope of band hummer, and galvanoscopic head is equipped with magnet; Link to each other with the insulation rope at electroscope; The other end of insulation rope passes insulation stock top and extends insulation stock bottom and be fixed on the rolling wheel of insulation stock bottom, and rolling wheel links to each other with the draw off gear that can drive its rotation, and the insulation stock is an expansion link.
Above-mentioned transmission line of electricity electroscope is equipped with pulley at the top of insulation stock, and the insulation rope is walked around pulley and fixed with the rolling wheel of insulation stock bottom.
Above-mentioned transmission line of electricity electroscope, said insulation stock bottom is hinged with two supports at least.
Above-mentioned transmission line of electricity electroscope, said draw off gear are the cranks that links to each other with the rolling wheel axle.
Above-mentioned transmission line of electricity electroscope, the said device of receiving is that reducing motor, battery and CS constitute, the output shaft of reducing motor links to each other with rolling wheel.
Adopt technique scheme; The utility model has following advantage: owing to adopted the insulation stock, in the bottom of insulation stock rolling wheel is installed simultaneously, the contact electroscope of band hummer is provided with the insulation rope that passes the insulation stock; And the other end of insulation rope is fixed with the rolling wheel of insulation stock bottom; Operating personnel just need not climb up cat head like this, just can on the ground the insulation stock that stretches be moved to the height of electric wire, measure directly whether voltage is arranged on the transmission line of electricity.Stock reaches near the electric wire that needs to survey as long as a member operating personnel will be insulated; Owing to existing power transmission line is the aluminium hinge line that has steel wire between employing is; Whether the magnet of electroscope bottom just can touch electroscope on the power transmission line easily and fast accurately, lean on the auditory tone cues of hummer to go out on the transmission line of electricity charged with regard to energy measurement.Simultaneously insulating bar rocks in order to prevent to measure, and is provided with the support that can play stabilization in the bottom of insulating bar.Can the insulation stock be shortened after measuring completion, will insulate to restrict through draw off gear and regain, be convenient for carrying.The utility model is simple in structure, is convenient for measuring and carries, and has improved surveying work efficient effectively, has improved the security when measuring.
