Abstract
The invention relates to an uninterrupted power falling type zinc oxide surge arrester, which comprises a zinc oxide surge arrester, wherein the upper end of the zinc oxide surge arrester can be connected with a moving contact through an operation ring, the moving contact is connected with a high voltage access point through a fixed contact, the lower end of the zinc oxide surge arrester is connected with a disconnector, the disconnector is connected with a soft connection, the lower end of the zinc oxide surge arrester is further connected with a grounding moving contact through a grounding moving contact, the grounding moving contact is arranged on an insulator through an installation bracket, the fixed contact and the high voltage access point are fixed on the insulator, and the zinc oxide surge arrester performs grounding discharge through the installation bracket. According to the present invention, if a problem exists in the zinc oxide surge arrester, the disconnector can be detonated in advance, the zinc oxide surge arrester can automatically fall off, and only operations of picking-off the zinc oxide surge arrester, replacements of the zinc oxide surge arrester and the disconnector, and re-closing are required to be performed to reuse the device without power cut. With the present invention, live working can be performed, safety and reliability of the power distribution network can be improved, failure points in the line are easily found, and routine maintenance workload can be derated.
Description
Technical field
The present invention relates to a kind of zinc oxide arrester of high tension insulator electrical apparatus industry, be specifically related to a kind of drop type zinc oxide arrester that do not have a power failure.
Background technology
After zinc oxide arrester is introduced into China, also occurs surge arrester failure in a large amount of actual motions and put little difficult discovery, changed inconvenient problem.The 10KV lightning arrester has installed disconnector additional at present, and the fault point finds that easily track replacement still needs outage to change, and this has brought great inconvenience for daily maintenance work.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of drop type zinc oxide arrester that do not have a power failure, can carry out live line working, improve the security reliability of power distribution network, be easy to find the line fault point, deduction and exemption line service amount.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of drop type zinc oxide arrester that do not have a power failure, comprise zinc oxide arrester 5, connection can be connected with moving contact by operation ring 3 in the upper end of zinc oxide arrester 5, moving contact 4 is connected connection by fixed contact 2 with the high pressure access point, connection is connected in the lower end of zinc oxide arrester 5 with disconnector, disconnector 6 and 8 connections that are connected, connection also is connected by ground connection moving contact 7 in the lower end of zinc oxide arrester 5 with the ground connection moving contact, ground connection moving contact 9 is installed on the insulator 11 by mounting bracket 10, fixed contact 2, high pressure access point 1 is fixed on the insulator 11, and zinc oxide arrester 5 is by the discharge of mounting bracket 10 ground connection.
Advantage of the present invention is:
1) can carry out live line working, improve the security reliability of power distribution network.
2) be easy to find the line fault point, deduction and exemption line service amount.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
With reference to accompanying drawing, a kind of drop type zinc oxide arrester that do not have a power failure, comprise zinc oxide arrester 5, connection can be connected with moving contact by operation ring 3 in the upper end of zinc oxide arrester 5, moving contact 4 is connected connection by fixed contact 2 with the high pressure access point, connection is connected in the lower end of zinc oxide arrester 5 with disconnector, disconnector 6 and 8 connections that are connected, connection also is connected by ground connection moving contact 7 in the lower end of zinc oxide arrester 5 with the ground connection moving contact, ground connection moving contact 9 is installed on the insulator 11 by mounting bracket 10, fixed contact 2, high pressure access point 1 is fixed on the insulator 11, and zinc oxide arrester 5 is by the discharge of mounting bracket 10 ground connection.
Operation principle of the present invention is;
By high pressure access point 1 access high-pressure side, when switching overvoltage and lightning overvoltage, discharge over the ground by mounting bracket 10, if zinc oxide arrester 5 has problem disconnector 6 to ignite in advance, zinc oxide arrester 5 meeting Automatic-fallings are obviously seen zinc oxide arrester 5 existing problems, at this moment only need zinc oxide arrester 5 is chosen down, change zinc oxide arrester 5 and disconnector 6, again close a floodgate and to recover to use, mustn't have a power failure.
