Description
Technical field
The present invention relates generally to live working tools test, refers in particular to a kind of electric line insulating rod test stand, can the multiple same electric pressure insulating bar of single test, when testing different electric pressure insulating bar, has test distance can quick adjustment.
Background technology
Hot line job is used widely in power grid enterprises and other power supply units, and hot line job can reduce the loss of supply because interruption maintenance causes, and greatly can improve power supply reliability.And live working tools is the important substance basis ensureing the distribution network live line work person and device security.In order to ensure the safe reliability of live working tools, industry standard regulation distribution protection class live working tools carries out 2 preventive trials every year, and period is spaced apart half a year.
What live working tools was main is detected as insulating property detection, and the industrial frequency withstand voltage that insulating property detect the insulation position of mainly Work tool detects, the detection of current Work tool causes Work tool detection lack of standardization owing to mostly detecting the lack of standardization of unit detecting electrode, cause Work tool to there is certain potential safety hazard, detection efficiency is low simultaneously.The lack of standardization of detection mainly refers to, the insulation position of Work tool can not effectively be detected.For this reason, the detection technique of Work tool will embody in power frequency withstand test process, and effective insulation position of Work tool is really detected.According to " electric-power safe instruments preventive trial code ", when carrying out insulating bar test, need first to regulate two interelectrode distances according to electric pressure, but due to test with electrode often by two independently electrodes, interelectrode distance can be caused when up putting insulating bar to move, causing test distance not meet regulatory requirements.
Summary of the invention
In order to solve electric line insulating bar test time interelectrode distance do not meet regulatory requirements, test time insufficient pressure shortcoming, the present invention is intended to design a kind of electric line insulating rod test stand, with the detection of specification electric line insulating bar, improve the efficiency that electric line insulating bar detects, reduce the labour intensity of staff.
The technical solution used in the present invention is:
When carrying out the test of electric line insulating bar, first according to the distance between electric pressure adjustment Slidable support bar and fixed support bar, then Slidable support bar and fixed support bar insulating bar cover plate is opened, the insulating bar of some is put on the insulating bar support of Slidable support bar and fixed support bar, cover Slidable support bar and fixed support bar insulating bar cover plate, fixed support bar connects high-voltage connection, ground wire on Slidable support bar, apply trial voltage, complete the test of a collection of electric line insulating bar.
Described a kind of electric line test device of insulating rod, its Slidable support bar and fixed support bar distance can adjust and its distance directly reads out by scale.
Described Slidable support bar and the insulating bar support of fixed support bar, have crescent shaped groove above it.
The present invention is adopted to have following advantage:
1, Slidable support bar and fixed support bar distance can adjust and its distance directly reads out by scale, can ensure that the test distance of insulating bar meets regulatory requirements
2, the insulating bar support of Slidable support bar and fixed support bar, has crescent shaped groove above it, can prevent the insulating bar be placed on insulating bar support from sliding.
In sum: a kind of electric line insulating rod test stand, can ensure the test distance of electric line insulating bar, the detection of specification electric line insulating bar, improves the efficiency that electric line insulating bar detects, and reduces the labour intensity of staff.
