Description
Technical field
The present invention relates generally to live working tools test, refers in particular to distribution wire mask standardization test unit, can carry out the test unit that the distribution wire masks that overlap the different regulations of identical electric pressure are tested more simultaneously.
Background technology
Live working of distribution network is used widely in power grid enterprises and other power supply units, and distribution network live line work can reduce the loss of supply causing due to interruption maintenance, can greatly improve power supply reliability.And live working tools is the important substance basis that ensures the distribution network live line work person and device security.In order to guarantee the safe reliability of live working tools, industry standard regulation distribution protection class live working tools carries out preventive trial every year 2 times, during be spaced apart half a year.
The main detection of live working tools is that insulating property detect, and insulating property detect the industrial frequency withstand voltage detection at the insulation position that is mainly Work tool, the detection of Work tool at present causes Work tool detection lack of standardization owing to mostly detecting the lack of standardization of unit detecting electrode, cause Work tool to have certain potential safety hazard, detection efficiency is low simultaneously.That detects lack of standardizationly 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 rules > >, when carrying out mask Insulation Test, conventionally the electrode of the inside of mask is a metal mandrel, and be placed in center in mask, mask outer electrode is ground-electrode, by conductive material, as metal forming etc., because power distribution network Work tool is complex-shaped, different, the real good contact test specimen insulation of detecting electrode position is not easy, and this is also to detect nonstandard major reason in the past.In addition, when insulation detects, a common withstand voltage test can only be tested one, and detection efficiency is low, causes general unit to be difficult to carry out such equipment test.
Summary of the invention
In order to solve lack of standard and the low shortcoming of detection efficiency of the test of distribution wire mask, the present invention is intended to design a kind of distribution wire mask standard test unit, detection with standard distribution wire mask, improve the efficiency that distribution wire mask detects, reduce staff's labour intensity.
The technical solution used in the present invention is:
When the distribution wire mask test of carrying out a plurality of same electric pressures, distribution wire mask is put into external electrode, interior electrode is penetrated in distribution wire mask, again internal electrode lead-wire and high-voltage connection are coupled together, on high-voltage conductive rod, apply trial voltage, by leakage current table, read leakage current, complete a collection of distribution wire mask test.
Described distribution wire mask standardization test unit, its base is equipped with a plurality of leakage current tables, and the low-pressure side of reometer and shell all link together, and is provided with a plurality of detection platform on base.
Described external electrode, is furnished with three external electrodes in a detection platform, to support distribution wire mask.
Described interior electrode, is comprised of electrode, insulating sleeve and lead-in wire, and insulating sleeve is positioned at the end of distribution wire mask at the trial.
Adopt the present invention to there is following advantage:
1, on base, be fixed with a plurality of leakage current tables and can place a plurality of detection platform and can guarantee once can detect a plurality of distribution wire masks.
2, in a detection platform, there are three external electrodes can balanced support distribution wire mask, increase the contact area of distribution wire mask and external electrode simultaneously, can more effectively detect distribution wire mask.
3, interior electrode adopts electrode to engage with insulating sleeve, the insulating sleeve of burn-oning in one end of electrode, insulating sleeve is positioned at the end of distribution wire mask at the trial, has elongated the electrical distance of interior electrode and external electrode, interior electrode pair external electrode electric discharge in the time of can preventing from testing.
In sum: distribution wire mask standardization test unit can a plurality of same pattern of one-time detection or the distribution wire mask of different patterns, have improved the efficiency that distribution wire mask detects, and have reduced testing staff's labour intensity.
