Embodiment Construction

[0017] see figure 1 , figure 2 , image 3 and Figure 4 Among them, a lightning protection device with a counting function is mainly used on overhead insulated conductors. The overhead insulated conductors 3 are provided with insulators 2 and piercing clamp electrodes 4. The lightning protection device includes a series gap arrester and a bracket 5. The series-gap arrester is composed of an arrester body 1 and a piercing clamp electrode 4 kept at a certain distance from one end of the arrester body 1, and the other end of the arrester body 1 is installed on one side of the insulator 2 through the bracket 5, A counter 6 is also connected to the arrester body 1 , and the arrester body 1 and the counter 6 are packaged as a whole through a silicone rubber composite jacket 7 .

[0018] The arrester body 1 is made of a core 8 and an insulating material 13 wrapped outside the core 8. The core 1 is composed of a metal oxide resistor 12 in series with a varistor 10. The varistor T...

Abstract

The invention discloses a lightning arrester with a counting function, mainly applied to an overhead insulation lead; the overhead insulation lead is provided with an insulator and a puncturing wire clamp pole. The lightning arrester comprises a series gap lightning arrester and a support; the series gap lightning arrester is composed of a lightning arrester body, and the puncturing wire clamp pole keeping a certain distance with one end of the lightning arrester body; the other end of the lightning arrester body is installed on one side of the insulator through a support; the lightning arrester body is also in connection with a counter, and the lightning arrester body and the counter are integrated. Compared with the prior art, the lightning arrester has the characteristics of simple structure, lower cost and convenient installation and maintenance, and avoids aging and cracking of the lightning arrester body and prolongs the service life of the lightning arrester body; the series gap lightning arrester has a gap distance, so that even the lightning arrester body breaks down, an apparatus can operate normally.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a lightning protection device with a counting function. Background technique [0002] At present, overhead insulated wires have been widely used in medium-voltage power lines. Under the action of lightning overvoltage, once the overhead insulated wires flashover to the ground, the power-frequency continuous current will flow along the breakdown channel. Due to the limitation of the outer insulation of the wire, the continuous current of the power frequency is very easy to be fixed at a certain position and continue to burn the wire, resulting in damage to the wire. Frequent continuous flow to prevent the occurrence of breakage accidents of insulated overhead conductors. In order to further understand the protection status of the arrester on the power line, the online monitoring measures of the arrester are adopted, and there are many characteristic physical quantities...
