Abstract

The invention discloses an electroscope test bench, which comprises a bottom platform. Three groups of supports are sequentially arranged from front to back on the bottom platform; each support group is composed of two telescopic rods; the two telescopic rods of the same group are respectively located at the left end and the right end of the bottom platform; wire is arranged between the two telescopic rods of each group; each telescopic rod is sequentially connected with a first base and the bottom platform via a rotating mechanism; a second base is arranged on the bottom platform; an adjusting rod is arranged on the second base; a cardan shaft is arranged on the adjusting rod; and a test platform is arranged on the cardan shaft. The electroscope test bench has the beneficial effects that the distance between the wire and the electroscope can be adjusted through the telescopic rods and the adjusting rod, the angle between the wire and the electroscope can be adjusted through the rotating mechanism and the cardan shaft, a plurality of line charged situations can be simulated so as to carry out comprehensive and accurate test on the electroscope, and possible serious consequences caused by inaccurate test results when a ideal test system is adopted for testing the electroscope can be avoided.

Description

Electroscope monitor station

Technical field

The present invention relates to a kind of electroscope detection system, especially electroscope monitor station.

Background technology

According to national regulation, high voltage electroscope must be tested having electric circuit or have on the equipment that corresponding conditions is provided before use, confirm after high voltage electroscope work well to carry out again the electrical verification of high-tension line to detect, and threshold values triggering judgement is carried out in the measurement that the principle of work of contactless transmission line of electricity high voltage electroscope is the intensity based on to power frequency electric field, traditional electric field and the check of calibration are all the checks in conjunction with rules GB/T 12720 alignment electric fields and calibration, can produce the known uniform field region of size and Orientation for calibrating with two blocks of plates that are parallel to each other.Adopt this calibration equipment can realize the uniform electric field of enough large known field intensity, but actual overhead transmission line is not this flat plate model, but the model of endless wire, add the interacting of crisscross, multi-circuit lines on the same tower of circuit, actual external electromagnetic field model can be more complicated, adopts Utopian flat plate model system cannot simulate the charged situation of actual track.

Summary of the invention

The object of the present invention is to provide electroscope monitor station, it can overcome the deficiencies in the prior art, can simulate the charged situation of multiple combination circuit, the check that makes contactless transmission line of electricity high voltage electroscope more comprehensively, more accurate.

The technical solution adopted for the present invention to solve the technical problems is: comprise base frame, three pack supports are installed on base frame from front to back successively, every pack support forms by two expansion links, two expansion links on the same group lay respectively at two ends, base frame left and right, between two expansion links of every pack support, wire is all set, every expansion link is all connected with base frame with the first base by rotating mechanism successively; The second base is installed on base frame, on the second base, adjusting lever is installed, universal shaft is installed on adjusting lever, installation testing platform on universal shaft.A fixed head of the each installation in described base frame rear and front end, between two fixed heads, leading screw is installed, mounted motor on base frame, the output shaft of motor is connected with leading screw one end, on the second base, threaded hole is set, and leading screw is through the threaded hole on the second base, threaded hole on the second base coordinates with threads of lead screw, between two fixed heads, guide pillar is installed, mounting guide sleeve on the second base, guide pillar coordinates with guide pin bushing; The equal installing insulating piece in described every expansion link upper end, conducting wire on collets; Described rotating mechanism is made up of holder and rotating shaft, and holder is arranged on the first base, and holder is U-shaped, and rotating shaft two ends are fixed on holder, and expansion link lower end is arranged in rotating shaft.

The invention has the beneficial effects as follows, can regulate wire and galvanoscopic distance by expansion link and adjusting lever, regulate wire and galvanoscopic angle by rotating mechanism and universal shaft, can also simulate the charged situation of various lines so that electroscope is carried out to comprehensive and accurate check, avoid the serious consequence that adopts idealized checking system to check the inaccurate the possibility of result of making to cause to electroscope.
