Description
Technical field
The utility model belongs to field of test instrument, relates to electric insulation apparatus ability meter, is specifically related to a kind of electric power gloves boots insulating property tester.
Background technology
Electric operating is various with insulating protection apparatus kind quantity, and wherein high tension insulating gloves, high-voltage insulating boots account for over halfly, need often do AC voltage withstand test and leakage current test to every apparatus, detect the High-Voltage Insulation security performance of every articles for use.
Traditional detection electric power adopts when test with the method for gloves, boots insulating property always, product to be tested is placed on the insulating mat of interim place mat, utilizes every test product of the manual contact of electrode of reometer.This insulating property method of testing, because means of testing is quite simple and crude, product to be tested quantity is more, and reometer is because of the electrode loose contact sensitive for damages, and transformer easily causes damaging because of frequently opening jumping; Since at every turn can only single-piece test, every/needs 5 minutes, only the test of gloves, boots just needs 6 days a medium electric power inspection center; Because means of testing is simple and crude, current measurement circuit lacks the reliably protecting measure, exists operator safety hidden danger.
The utility model content
The designer is in putting into practice the contact activity, find that existing electric power exists above-mentioned defective with the High-Voltage Insulation Testing Method of Safety of gloves, boots, improve through constantly exploring, purpose is to provide a kind of electric power gloves boots insulating property tester, testing efficiency be can improve, testing equipment and personal safety ensured.
Technical solution adopted in the utility model is a kind of electric power of design gloves boots insulating property tester; its structure comprises: reometer; control desk; in control desk, be connected with test control circuit mutually with reometer; adopt one or more electric current incoming line in parallel with the incoming line of reometer; the measuring switch of connecting on every incoming line; link to each other with electrode in being arranged on corresponding insulation pond by measuring switch; each electrode links to each other with the reometer ground wire by normally closed switch; the protector of establishing in parallel with normally closed switch is same as the high-voltage output line electrode of reometer incoming line with transformer high-voltage output line electrode quantity in parallel.
The utility model is owing to adopt technique scheme and measure, traditional electric power is improved with gloves boots insulating property method of testing, designed this electric power gloves boots insulating property tester, a kind of tester of standard is provided for electric power detection department, both can do the AC voltage withstand test of test product, can do the leakage current test of test product again; In operating process,, can utilize the existing overcurrent protection function of transformer if the test product insulation breakdown takes place, if the test circuit open circuit takes place, loop voltage raises, the breakdown discharge of discharge tube meeting, can guarantee that personnel and instrument and equipment can not be on the hazard, and eliminate safe hidden trouble; When doing AC voltage withstand test, can realize that many test products test simultaneously, saved the time, improved efficient.
