Tool for jointing temporary lead wire under live working on rainy day for distribution line and method thereof

Abstract

The invention discloses a tool for jointing a temporary lead wire under live working on a rainy day for a distribution line, which comprises an operating rod, and a temporary jointing clamp connected by a connecting part, wherein the operating rod is formed by assembling an upper rod, and one to two sections of lower rod; the middle and lower part of the upper rod is externally wrapped with a section of insulation sleeve, the insulation sleeve is provided with a plurality of silicon rubber umbrella skirts at interval, and the upper end and the lower end of the upper rod are respectively provided with an universal connector and a middle connector; the upper end and the lower end of the lower rod are respectively provided with a connector matched with the middle connector of the upper rod, and a middle connector; the temporary jointing clamp comprises a double-wire clamp body, an upper binding clip and a lower binding clip; the upper part of the connecting part is of a twelve point socket connected with the double-wire clamp body, and the lower end thereof is of a clamp port matched with the universal connector of the upper end of the upper rod of the operating rod. The jointing tool can make the operator appropriately isolate from the electrified body with different potential on a rainy day, and realizes the indirect operation to the electrified body.

Description

technical field [0001] The invention relates to a tool for live work of a power distribution line in a power system, in particular to a tool and a method for live-lapping temporary leads of a power distribution line in rainy days. Background technique [0002] There are two methods for live work on 10kV distribution lines - the method of insulating gloves and the method of insulating operating rods. [0003] The insulating glove method is a method in which the operator stands on an insulating bucket or an insulating platform, isolating from the grounding body, and wearing insulating gloves to directly operate the charged body. This method has a relatively short distance between the operator and the charged body. However, in rainy days, due to the high air humidity, the air conductivity increases, the discharge distance decreases, and the personal safety of personnel is endangered, so it cannot be used. [0004] The insulating operating rod method is a method in which the op...

Problems solved by technology

This method uses the insulating operating rod to isolate the personnel from the charged body. In rainy weather, the insulating operating rod absorbs moisture, the surface resistance decreases, and the leakage current increases during operation, which threatens the safety of the operating personnel, so it cannot be used.
