Abstract
This utility model relates to finder outside a kind of transmission circuit insulator string, there is telescopic insulating bar, telescopic insulating bar end is provided with insulated handle, and telescopic insulating bar front end is provided with coupling bar, and on coupling bar, rotating connection has a convex mirror；This utility model simple in construction, easy to use, reliable and stable, there is good application value, be mainly used in the middle of insulator chain flashover walkaround inspection.
Description
Technical field
This utility model relates to ultra-high-tension power transmission line safety auxiliary tool technical field, especially a kind of transmission line insulator
Finder outside substring.
Background technology
In ultra-high-tension power transmission line, when running insulator chain and meeting with the situations such as flashover, line fault can be caused to trip, defeated
Electricity operation maintenance personnel needs that fault location is stepped on bar in time and makes an inspection tour, and finds out the flashover position (flashover of thunderbolt, flashover insulator chain
Refer to that, when the gas around solid insulator or liquid dielectric are breakdown, along the phenomenon of solid insulator surface-discharge, it is put
Voltage during electricity is referred to as flashover voltage, and after there is flashover, interelectrode voltage quickly falls to zero or close to zero, flashover passage
In spark or electric arc make insulating surface hot-spot cause carbonization, damage surface insulation), step on bar in transmission line malfunction location
Check that in work, due to the human body the to be ensured safe distance to wire, additionally part line insulator is mounted with anti-bird baffle plate,
There is vision dead zone when observing outside insulator chain, cause insulator chain defect to be difficult to be found and omit, to transmission line of electricity
Safe operation leaves major hidden danger.
Summary of the invention
The purpose of this utility model seeks to solve existing high voltage power transmission insulator O&M perambulator when there is flashover
The problems referred to above that member's maintenance exists when observing, it is provided that a kind of simple in construction, easy to use, electric transmission line isolator safely and efficiently
Finder outside string.
Concrete scheme of the present utility model is: finder outside a kind of transmission circuit insulator string, have telescopic absolutely
Edge action bars, telescopic insulating bar end is provided with insulated handle, and telescopic insulating bar front end is provided with coupling bar, couples
On bar, rotating connection has a convex mirror.
Coupling bar described in this utility model includes cross bar and montant, and cross bar and montant are mutually perpendicular to layout and are connected to one
Rising, one end of described cross bar is socketed on telescopic insulating bar, and the upper end of described montant is rotationally connected with described convex mirror.
Make an inspection tour after operating personnel's rod-rising tower at cross arm of tower (operating personnel keep with electrical body 220kV3 rice,
110kV1.5 meter ampere full distance), rotate regulation convex mirror angle, extract telescopic insulating bar out, convex mirror is at insulator chain
Outside is observed, and can clearly see outside edge substring whether existing defects clearly；Observe the complete telescopic insulating bar of direct withdrawal, put
Enter kit bag, operating personnel's lower beam；Owing to finder is an entirety, only needs one man operation, improve working performance, with
Hidden defects outside Shi Faxian insulator chain, it is ensured that transmission line of electricity safe operation.
This utility model has the advantages that
1, can clearly find hidden defects outside insulator chain, reduce operating personnel and repeat to step on bar inspection number of times, alleviate
The labor intensity of operating personnel, improves working performance.
2, ensure that operating personnel's reliability to the safe distance of electrical body.
This utility model simple in construction, easy to use, reliable and stable, there is good application value.
Accompanying drawing explanation
Fig. 1 is this utility model population structure schematic diagram.
In figure: 1 convex mirror, 2 montants, 3 cross bars, 4 telescopic insulating bars, 5 insulated handles.
Detailed description of the invention
Seeing Fig. 1, this utility model is finder outside a kind of transmission circuit insulator string, has telescopic insulation behaviour
Making bar 4, telescopic insulating bar end is provided with insulated handle 5, and telescopic insulating bar front end is provided with coupling bar, coupling bar
Upper rotating connection has a convex mirror 1.
Coupling bar described in the present embodiment includes cross bar 3 and montant 2, and cross bar and montant are mutually perpendicular to layout and are connected to one
Rising, one end of described cross bar 3 is socketed on telescopic insulating bar 4, and the upper end of described montant 2 rotates with described convex mirror 1
Connect.
Make an inspection tour after operating personnel's rod-rising tower at cross arm of tower (operating personnel keep with electrical body 220kV3 rice,
110kV1.5 meter ampere full distance), rotate regulation convex mirror angle, extract telescopic insulating bar out, convex mirror is at insulator chain
Outside is observed, and can clearly see outside edge substring whether existing defects clearly；Observe the complete telescopic insulating bar of direct withdrawal, put
Enter kit bag, operating personnel's lower beam；Owing to finder is an entirety, only needs one man operation, improve working performance, with
Hidden defects outside Shi Faxian insulator chain, it is ensured that transmission line of electricity safe operation.
This utility model has the advantages that
1, can clearly find hidden defects outside insulator chain, reduce operating personnel and repeat to step on bar inspection number of times, alleviate
The labor intensity of operating personnel, improves working performance.
2, ensure that operating personnel's reliability to the safe distance of electrical body.
This utility model simple in construction, easy to use, reliable and stable, there is good application value.
