Special measuring tool for arcing horn of overhead transmission line

Abstract

The invention provides a special measuring tool for an arcing horn of an overhead transmission line. The special measuring tool includes a measuring tool body, a handle is arranged at the right end ofthe measuring tool body; stop blocks are fixedly connected to the left and right ends of the handle; the left end of the handle is fixedly connected with a telescopic rod; the left end of the telescopic rod is fixedly connected with a connecting block; according to the special measuring tool for the arcing horn of the overhead transmission line, insulating pads are arranged on the outer surfacesof the handle and the stop blocks; the insulating pads can effectively block the transmission of high-voltage electricity, therefore, an insulation effect is achieved, the safety of measuring personnel using the measuring tool body to measure the arcing horn is greatly improved; the special measuring tool for the arcing horn of the overhead transmission line is connected with the connecting sleevein a sleeved mode through the connecting shaft and connected with the inner clamping block and the outer clamping block in a clamped mode, the connecting mode is relatively fixed, the position of themeasuring instrument can be adjusted to enable the measuring instrument to be attached to a to-be-measured part, and therefore more accurate data can be measured, errors are reduced, and use is convenient.

Description

technical field [0001] The invention relates to the field of electric power equipment auxiliary equipment, and more specifically, relates to a special measuring tool for arc strike angle used for overhead power transmission lines. Background technique [0002] The arc angle, also known as the angle gap, is the insulator protection fitting on the overhead transmission line. As one of the effective lightning protection devices, the arc angle is installed at the end of the insulator string with a certain arc gap. Its structure is simple and easy to maintain. , used in conjunction with the automatic reclosing switch in the system, it can not only ground the lightning current in time, but also provide uninterrupted power supply to the user, so as to prevent the surface flashover of the insulator, protect the electrical equipment, and maintain the normal operation of the line. In order to ensure the line For normal operation, the position of the arc angle must be accurate. There i...

Problems solved by technology

[0003] At present, the special arc angle measurement tools on the market are made of insulating materials, so there is no additional insulation treatment on the handle. When the measurer uses the measurement tool, the measurement tool may accidentally leak and conduct electricity, and the measurement The phenomenon of electric shock, the safety performance is average, and the position of the measuring instrument of some special measuring tools for arcing angle is fixed, and the direction cannot be rotated. When using it, the measurement data may be inaccurate and there may be errors, which is not conducive to use.
