Problems solved by technology

Most of the existing lightning arresters are not equipped with an electric shock display device. After suffering an electric shock and causing a failure, the shape is the same as when it was not subjected to an electric shock. As a result, it is impossible to find that the lightning arrester is damaged in time, which brings potential safety hazards.

Embodiment 1

[0018] Such as figure 1 , 2 As shown, a zinc oxide surge arrester with ring-shaped tripping and fault indication includes an insulator 3 and a surge arrester body 7. The top of the insulator 3 is supported by an overhead wire 2, and the bottom of the insulator 3 is fixed on the cross arm 4. The insulator 3 The bottom is also fixed with a mounting bracket 5, and the bottom of the arrester body 7 is fixed with an insulating bracket 8. The mounting bracket 5 and the insulating bracket 8 are connected by bolts. It is directly installed and fixed on the top of the arrester body 7, which can effectively ensure the gap distance with the overhead conductor 2, ensure the discharge path, and not be affected by the external environment. The bottom of the arrester body 7 is connected with a tripping indicator 9, which includes a shell body 11, the upper surface of the housing 11 is provided with a connection hole 15 for connecting with the arrester body 7 and having an internal thread, s...

Abstract

The invention relates to the field of electric power, in particular to an annular tripping type zinc oxide arrester with fault indication. The annular tripping type zinc oxide arrester with fault indication comprises an insulator and an arrester body, wherein the bottom of the insulator is also fixedly provided with a mounting bracket; the bottom of the arrester body is fixedly provided with an insulation bracket; the mounting bracket and the insulation bracket are connected through a bolt; the top end of the arrester body is provided with a round compression ring; the bottom of the arrester body is connected with a tripping indicator; the tripping indicator comprises a shell, wherein a signal detector, a detonating groove and an identification groove are arranged in the shell; the openingof the detonating groove and the opening of the identification groove are fixedly provided with a sealing cover in a sealing way; an electric detonator is arranged in the detonating groove; an identification spring is arranged in the identification groove; one end of the identification spring is connected to the bottom surface of the identification groove; and the other end of the identificationspring is connected with an identification belt. The arrester is simple in installation, can effectively avoid single-phase ground connection faults, and can warn in time to repair when faults happen.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an annular trip type zinc oxide arrester with fault indication. Background technique [0002] With the continuous lengthening of power distribution network lines and the popularization of insulation design, disconnection accidents caused by lightning damage are prominent, and personal accidents are easily caused after disconnection. The statistics of insulator breakdown accidents are also increasing, which has seriously threatened the safe operation of distribution network lines. . In the transmission line, as an important overvoltage protection device, the arrester is installed on the transmission tower and connected in series and parallel with the line insulator to limit the lightning and operating overvoltage of the transmission line and improve the reliability of the system operation. [0003] At present, there are many defects in lightning protection products on the market, su...
