Problems solved by technology

[0005] However, this kind of lightning protection post insulator still has the following disadvantages: the discharge point of the arc striker and the lower steel foot is exposed, and it is easy to accumulate dirt, which affects the discharge action
In addition, the discharge gap between the arc striker and the lower steel foot is fixed, but the external weather changes frequently, which may easily lead to misoperation or discharge failure.

Abstract

The invention discloses a lightning protection post insulator which utilizes an elastic conductive coil to reset the discharge gap, which comprises an insulator, an upper discharge part and a lower discharge part; the inside of the insulator is provided with a sealed cavity; the upper discharge part is provided with an upper discharge terminal located on the upper part of the sealed cavity The lower discharge part includes a lower discharge rod, an insulating slide tube, an elastic conductive coil for providing a reset force for the lower discharge rod, a conductive installation base and a conductive installation pillar; the lower discharge rod is provided with a lower discharge end located at the lower part of the sealed cavity and a The end of the sliding column inserted into the insulating slide tube; the upper end of the elastic conductive coil is fixedly connected with the lower discharge rod, and the lower end of the elastic conductive coil is fixed on the conductive installation base; the upper discharge end of the upper discharge part and the lower discharge end of the lower discharge part There is a discharge gap. The invention utilizes the elastic conductive coil to generate electromagnetic force to drive the lower discharge part to move down to increase the discharge gap; on the other hand, it provides reset elastic force for the lower discharge part, which helps to reduce parts and simplify the structure.

Description

technical field [0001] The invention belongs to the technical field of lightning strike protection for electric overhead insulated lines, and in particular relates to a lightning protection pillar insulator which utilizes an elastic conductive coil to reset a discharge gap. Background technique [0002] After the overhead line is struck by lightning, power frequency freewheeling will occur. The so-called power frequency freewheeling means that after the overhead line is struck by lightning, a lightning arc will be generated between the overhead line and the metal cross arm. The survival time of this lightning arc is very short, but it forms The conductive channel between the overhead line and the cross-arm is opened, so that the power supply of the overhead line is short-circuited to the ground (cross-arm). In terms of freewheeling, the greater the grounding resistance of the crossarm or pole, the smaller the power frequency freewheeling, and the easier it is to cut off the ...
