Auxiliary device for insulation resistance detecting of megohmmeter

Abstract

The invention, which relates to the field of auxiliary tools of power equipment detecting, discloses an auxiliary device for insulation resistance detecting of a megohmmeter. The auxiliary device comprises a connecting frame, an insulating rod, a positive electrode wire, a negative electrode wire, positive electrode rods and negative electrode rods. The insulating rod is connected with the connecting frame; the positive electrode rods and the negative electrode rods are spaced in parallel; the distance between any two adjacent positive electrode rod and negative electrode rod is equal to the length of the insulator, so that the two ends of the insulator can be in contact with the positive electrode rod and negative electrode rod. Besides, a first conductor assembly and a second conductor assembly that are communicated with the positive electrode wire and the negative electrode wire are arranged on the connecting frame respectively. All positive electrode rods are fixed on the connecting frame by the first conductor assembly and are communicated with the positive electrode wire; and all negative electrode rods are fixed on the connecting frame by the second conductor assembly and are communicated with the negative electrode wire. When the device is in use, the positive electrode wire and the negative electrode wire are connected with the megohmmeter. Detection can be performed only by holding the insulating rod by one hand; and the detection of the insulating rod of the insulator can be performed safely, reliably, rapidly, and efficiently.

Description

technical field [0001] The invention relates to the technical field of electric equipment detection auxiliary tools, in particular to a megger insulation resistance detection auxiliary device. Background technique [0002] With the reform and development of power grid enterprises, the demand for power supply is increasing, and ceramic insulators and glass insulators are more and more widely used in transmission lines. However, due to the damage of the external environment, mechanical force and electrical quantity, the aging of the insulator is accelerated, and the aging of the insulator greatly reduces the insulation performance. Especially under the action of high frequency and high temperature of lightning current, thermal breakdown is prone to occur; under the action of high temperature caused by pollution flashover fault current or leakage current, the insulation performance of insulators is greatly reduced, or even loses insulation performance, causing hidden dangers in...
