Abstract

The invention relates to a detecting tool for an electrical power system, in particular to a labor-saving porcelain insulator zero-value live-detection electrospark fork tool, and belongs to the high-tension transmission line porcelain insulator zero-value live-detection tool. A metallic electrospark fork discharging gap is formed at the front end of an insulating bar; a fixing ring is connected to the front part of the insulating bar; an insulating rope is penetrated through the fixing ring; and one end of the insulating rope is connected with a permanent magnet. Through the way that the front end of the electrospark for traditional insulator live-detection is suspended and pulled by the insulating rope, the labor intensity of an operator due to the moment of the electrospark fork is reduced; at the same time, the front shaking problem of the electrospark fork is reduced; the positioning accuracy is improved. In addition, compared to the hook suspending way, the way of using the permanent magnet to adsorb an iron tower is convenient to operate, and the structure is simple. The tool can greatly improve the working efficiency of the live operating personnel, and ensure the personal security of the operating personnel.

Description

technical field [0001] The invention relates to a power system detection tool, in particular to a labor-saving porcelain insulator zero-value electrification detection spark fork tool, which is a high-voltage transmission line porcelain insulator zero-value electrification detection tool. Background technique [0002] At present, due to the lack of power outage plans for transmission lines, the live detection of porcelain insulators has become very popular. The live detection is generally carried out by the spark fork method, that is, using the voltage distribution on the good insulator sheet, the spark fork short-circuits the insulator and there will be a sound , to judge whether the insulator is zero value. This method is currently the most effective method for judging the zero value of an insulator when it is charged. However, this method requires workers to go up the tower and hold a 3m-5m long insulating rod to operate (220kV-500kV varies according to the structure of ...
