Abstract
The utility model relates to an on-line monitoring device of transformer substation lightning arrester, which mainly comprises a lighting arrestor, an insulating base, a column and a monitoring instrument, wherein the upper end and the lower end of the monitoring instrument are respectively connected with the lighting arrestor and the column through flat iron, a flexible connecting wire is arranged between the flat iron of the monitoring instrument which is connected with the lighting arrestor, and connecting threaded holes are arranged on a preformed section of the flat iron which is connected with the upper end and the lower end of the monitoring instrument. The on-line monitoring device of lightning arrester has the advantages of low failure rate and can replace the on-line monitoring instrument of lightning arrester in the operation.
Description
Technical field
The utility model relates to the monitoring device of a kind of transformer station lightning arrester, specifically a kind of lightning arrester on-Line Monitor Device.
Background technology
Transformer station's lightning arrester on-Line Monitor Device connected mode is at present, and lightning arrester is installed on the insulator foot, and insulator foot is installed on the pillar, and monitor is connected pillar ground connection respectively in two ends up and down with pillar with lightning arrester by band iron.Be in operation owing to reasons such as temperature variation and vibrations, it is bigger that monitoring device is subjected to stress, and failure rate is higher.The essential terminal ground connection that keeps because lightning arrester is in operation, existing connected mode is in operation and can not changes lightning arrester on-line monitoring instrument.
The utility model content
It is low that task of the present utility model provides a kind of failure rate, can be in operation to change transformer station's lightning arrester on-Line Monitor Device of lightning arrester on-line monitoring instrument.
For realizing above-mentioned task, technical solution of the present utility model is:
A kind of lightning arrester on-Line Monitor Device, mainly constitute by lightning arrester, insulator foot, pillar, monitor, monitor is connected with pillar with lightning arrester by band iron respectively at two ends up and down, between monitor and band iron that lightning arrester is connected, the line that is flexible coupling is set, on the reservation section of band iron that two ends connect the connection screw is set up and down at monitor.
It is low to the utlity model has failure rate, can be in operation to change the advantage of lightning arrester on-line monitoring instrument.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of lightning arrester on-Line Monitor Device, mainly by lightning arrester 1, insulator foot 2, pillar 3, monitor 7 constitutes, monitor is connected with pillar 3 with lightning arrester 1 by band iron 4 respectively at two ends about in the of 7, pillar 3 ground connection, between monitor 7 and band iron 4 that lightning arrester 1 is connected, fix the line 6 that is flexible coupling by bolt 5, to reduce the suffered stress of monitoring device, on the reservation section of monitor band iron that two ends connect 4 about in the of 7, make and connect screw 8, can fix an interim connecting line 9 band iron 4 connections up and down by bolt 5, so that in the time of maintain and replace monitor 7, do not influence lightning arrester 1 ground connection.
Claims (1)
1, a kind of lightning arrester on-Line Monitor Device, comprise lightning arrester, insulator foot, pillar, monitor, monitor is connected with pillar with lightning arrester by band iron respectively at two ends up and down, it is characterized in that: between monitor and band iron that lightning arrester is connected, the line that is flexible coupling is set, on the reservation section of band iron that two ends connect the connection screw is set up and down at monitor.
