Description
Technical field
The present invention relates to insulator detection device, specifically a kind of wireless insualtor detector aid.
Background technology
If there is Faulty insulator in electric power line pole tower insulator chain, once there is overvoltage to occur, will result in absolutely
Edge internal breakdown, porcelain completely lose insulating capacity, so as to produce low, zero resistance insulator.It is instantaneous that thunderbolt and pollution flashover are produced
Short circuit current may cause the thermal explosion of crossing of faulty insulator when serious, therefore produce string accident, and transmission line of electricity is pacified
Row for the national games constitutes great threat.In China, porcelain insulator is a kind of most popular insulator, and its annual deterioration rate is
6 ‰, far above 2 to the three/100000ths of the developed countries such as Japan.Therefore, it is necessary to periodically examine to line insulator
Survey, and change faulty insulator in time.
A kind of existing wireless insualtor detector for detecting the spread voltage value of electric transmission line isolator, it includes surveying
Examination end, insulating bar and the main frame for receiving and showing in real time the spread voltage of surveyed insulator, test lead include one
Individual detector, is connected with two voltage probes on detector.During use, test lead is arranged on into the front end of insulating bar, operation
Personnel are the test that hand-holdable insulating bar carries out insulator.
During insulator is measured piecewise, due to operating personnel's technical merit, tower structure type, operation field condition
Etc. the impact of factor, the insulating bar Jing in detection process is caused often to occur rocking, two voltage probes accurately cannot be contacted
Insulator two ends steel cap and steel foot, therefore operating personnel needs to adjust repeatedly operation, gets off for a period of time, the arm of operating personnel
Will appear from aching symptom, cannot operate, which not only adds the working strength of operating personnel, and test easily occur and miss
Difference.
The content of the invention
The technical problem to be solved is to provide a kind of wireless insualtor detector aid, and the instrument can be with
Less important work personnel carry out the test job of insulator, so as to mitigate the workload of operating personnel, and improve test accuracy.
In order to solve above-mentioned technical problem, the present invention is adopted the following technical scheme that：Wireless insualtor detector aid,
It is provided with one parallel to its axial direction and insertion hollow straight tube tube wall is led with the hollow straight tube for thoroughly doing away with edge on hollow straight tube

Fixed mechanism, lower end are provided with the second fixed mechanism.
The width of the guide groove and notch disclosure satisfy that the voltage probe of wireless insualtor detector wherein slidably,
Spacing distance between notch is equal to the spacing distance between two voltage probes.
First fixed mechanism and the second fixed mechanism are used to be fixed on the supporter beside insulator, hollow straight to ensure
Pipe is stablized, and the first fixed mechanism and the second fixed mechanism can be that bandage, hook, dop etc. are any suitable for fixed connection
Device.
For the sake of concise description, the wireless insualtor detector aid described in present invention below is referred to as this instrument.
During use, this instrument is stabilized in beside insulator by the first fixed mechanism and the second fixed mechanism, is made hollow
Straight tube is maintained at vertical state and is alignd with insulator chain.Insulating bar related test lead can be stretched into hollow straight tube afterwards
Interior, operating personnel can drive two voltage probes to move up and down in guide groove with hand-held insulating bar, wait to reach what is need to detected
During certain piece insulator, rotating insulated action bars makes two voltage probes screw in corresponding draw-in groove, and such two voltage probes are just
It is fixed on insulator steel cap and steel foot well, the purpose for measuring insulator piecewise is reached with this.
Knowable to above-mentioned technical proposal, the range of activity of insulating bar and test lead is limited to hollow straight tube by this instrument
It is interior, rocking for insulating bar is in so avoiding, and test lead can maintain stable measurement attitude, therefore on tower
Operating personnel only needs easily to slide by a people, rotating insulated action bars carries out the test of insulator, while subtracting to greatest extent
Lack the problem for surveying the detection difficult caused due to the reason such as personnel's level of skill and shaft tower type during zero, operating personnel's
Workload also can mitigate significantly, and work efficiency is improved, it is often more important that test result is more accurate.
Used as the improvement of the present invention, the cross section of the hollow straight tube is square.
