Background technology
For improving the high situation of transmission line lightning stroke trip-out rate; since 2011; State Grid Corporation of China carries forward vigorously transmission line located Lightning Transformation engineering; comprehensively have employed and install leakage conductor additional, reduce pole tower ground resistance, improve line insulation, the series of measures such as lightning receptor, controllable discharge lightning rod, negative angle protecting pin, erection coupling ground wire are installed, achieve positive effect.Particularly leakage conductor lightning protection effect is very remarkable, and lightning stroke trip event appears in shaft tower hardly that installed leakage conductor additional.
Leakage conductor is as current Lightning stroke Protection Measures for Over-Head Lines the most reliably, and its effect obtains the consistent accreditation of grid company, and hanging net operation quantity also grows at top speed.Along with leakage conductor runs the growth of quantity, transmission line caused by lightning strike obtains effective control, but the O&M of leakage conductor also becomes an outstanding problem pendulum in face of electric company simultaneously.Existing leakage conductor standard DL/T 815-2012 " transmission line of alternation current polymeric metal oxide surge arrester " to line arrester with gaps only propose " need regular line walking (every year at least one times; before thunderstorm season); range estimation lightning arrester outward appearance whether have damaged condition; and the action data of recording counter " O&M requirement, but from existing operating experience, all there is great defect pipelines in leakage conductor body and series gap, moreover along with the growth of working time, its failure rate is inevitable constantly to be increased.How to the running status of leakage conductor particularly in state of insulation detect, be the problem that Utilities Electric Co. pays special attention to.
If carry out power failure routine test according to transformer station's lightning arrester, leakage conductor need be dismantled go back to ground and test, workload is huge and relate to long power cut problem, all unrealistic from experimental safe, workload and power supply reliability.
Therefore, from equipment safety operation and fortune inspection efficiency two aspect, needing that research is a kind of badly can the measuring device with electricity of state of insulation in safe and efficient detection line lightning arrester.
Summary of the invention
The purpose of this utility model is, in order to solve existing line lightning arrester operating maintenance Problems existing, proposes a kind of leakage conductor state measuring device with electricity based on electric field method.
Realizing the technical solution of the utility model is, a kind of leakage conductor state measuring device with electricity based on electric field method is made up of electric-field sensor, positioning clamp, insulating bar, display, signal transmssion line, display fixing device, rotatable bolt and control lever connector.Electric-field sensor is arranged on positioning clamp; Insulating bar connects the shank of positioning clamp by rotatable bolt; Display is arranged on the top of insulating bar by display fixing device; Electric-field sensor connects display by signal transmssion line.
Positioning clamp is falcate structure, and positioning clamp convex surface middle part is provided with location clamp handle, and electric-field sensor can be installed in positioning clamp concave surface middle part.
Insulating bar is made up of folding more piece pole, connects each pole by control lever connector.
Principle of work of the present invention is: the present invention is based on leakage conductor body and support composite insulator generation built-in electrical insulation defect surperficial axial electric field can be caused to change this principle, by accurately measuring its surface electric field distribution situation, contrast with regular link lightning arrester surface axial electric field distribution curve, find lightning arrester built-in electrical insulation defect, and accurate location defect position.
The beneficial effects of the utility model are, the utility model device have do not have a power failure, noncontact, the advantage such as easy and simple to handle, result is accurate, greatly can improve leakage conductor state-detection efficiency, assessment leakage conductor state of insulation, significant to leakage conductor safe and stable operation.
