Abstract
The utility model discloses a tool for testing zero value of an insulator chain. The tool comprises a zero value tester and is characterized by further comprising a telescopic insulating pole and two testing probes, wherein the zero value tester is fixedly mounted at the tail end of the telescopic insulating pole; the testing probes are mounted at the top end of the telescopic insulating pole; the distance between the two testing probes is equal to that between two metal objects at two ends of the insulator; and the two testing probes are respectively connected to the signal input end of the zero value tester via conducting wires. By adopting the tool provided by the utility model for testing, the zero value of the insulator chain can be tested by maintenance/experiment personnel only sitting on a panel girder framework instead of climbing on the insulator chain and leaning out, so that the safety hazards of falling down from a high place is avoided and the test safety is enhanced; in addition, the tool can be simply and conveniently operated and carried, and is particularly suitable for 220 kV voltage class.
Description
Technical field
The utility model relates to a kind of experimental tool of insulator chain null detection.
Background technology
The null detection of Substation Insulator string is the main mode that detects the insulator dielectric performance, is that routine test must be done project, surveys unsettled layout, not anti-reliably high-altitude drop device outward but transformer station's inner insulator string is installed in panelgirder.The null detection of insulator chain at present mainly relies on the null detection instrument to test, existing null detection instrument test bodies and test probe are installed together, the maintainer is when experimentizing, have to body is leant out, climb on insulator chain, just can test, have the high-altitude danger of falling, and be not easy operation.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, and a kind of insulator chain null detection instrument safe in utilization, easy and simple to handle, easy to carry is provided.
For addressing the above problem, technical solution of the present utility model is: a kind of insulator chain null detection instrument, and it comprises null detection instrument, telescopic insulating bar and two test probes, the null detection instrument is fixedly mounted on telescopic insulating bar end; Test probe is installed in telescopic insulating bar top, and the distance between two test probes is a distance between the metal object of insulator two ends; Two test probes are connected the signal input part of null detection instrument respectively by lead.
The lead of two test probes of above-mentioned described connection and null detection instrument places in the cavity of telescopic insulating bar.
Above-mentioned described test probe is rotatably installed in telescopic insulating bar top by turning axle.Like this, the opening angle of two test probes is adjustable.
The utility model separately is arranged on null detection instrument and two test probes the two ends of telescopic insulating bar, the maintenance experimenter only need be sitting on the panelgirder framework, open null detection instrument power switch, adjust the length of insulation expansion link, adjust the opening angle of test probe, two test probes are connected with the metal object at insulator two ends can realize null detection, body need not be leant out, climb on insulator chain, avoided the high-altitude danger of falling, increased the security of test, and easy and simple to handle, easy to carry.Telescopic insulating bar can be adjusted length, far and near insulator chain is set all is easy to test.The opening angle of two test probes is adjustable, and no matter the thickness of insulator can both be used, and the scope of application is wide.The utility model is adapted at the 220kV electric pressure most and uses.
