Description

Technical Field

[0001] The present invention relates to the technical field of electric tools, and in particular to an auxiliary installation fixture for a line lightning arrester and a use method thereof. Background Art

[0002] Line type arrester is used for 6~220kV AC transmission and transformation lines. It is designed to limit the lightning overvoltage of the line and improve the lightning resistance level of the line. It is a new type of arrester specially designed to reduce the trip rate of the system caused by lightning faults. It is suspended and installed on the transmission tower. The basic structure of the line arrester is mainly no gap and external series gap, among which the external series gap is divided into the gap of the insulating support and the pure air gap. The insulation coordination or use effect proves that the gapped and gapless line arresters can effectively prevent the flashover accidents of the insulator string. During power construction or line-type lightning arrester installation work, there is a lack of a dedicated location or platform for installing the line lightning arrester on the pole. During the operation of installing the line lightning arrester on the pole, the workers can only support it with the weight of their arms, and there is a risk of the line lightning arrester falling. At the same time, since the line lightning arrester body is heavy, the workers will become tired when holding the line lightning arrester due to excessive weight on their arms, which affects the quality and efficiency of the work and is not conducive to standardized operations.
