Description
Technical field
The present invention relates to the supporting method of testing of a kind of lightning arrester with the release unit performance.
Background technology
The lightning arrester auxiliary products of release unit as lightning arrester, the use of connecting with lightning arrester generally is directly installed on the arrester ground side, isolates lightning arrester and earth potential.
The mounting means of release unit and supporting lightning arrester can be divided into: integral type and accessories type.
When lightning arrester normally moves, release unit should have the tolerance identical with lightning arrester, and can reliably be failure to actuate, have only when the lightning arrester fault, thereby lightning arrester and system are isolated in the release unit action, anti-locking system sustained fault, and provide visual identification, so that replace the lightning arrester of fault as early as possible.
Only be that rush of current and operating duty resistance test verify that performance that it reliably is failure to actuate and ampere-time characteristic verify the performance that it can action message to the testing requirements of release unit among act.std GB11032-2000, GB/T7327-2008 and the IEC60099-4:2009.But find that in actual motion the release unit that can satisfy these standard-requireds still can't well cooperate with lightning arrester, the situation of release unit tripping or malfunction usually occurs.Applicant of the present invention is in order to test the supporting performance with release unit of lightning arrester, the deficiency that the release unit standard that has by a large amount of release unit performance tests and on-the-spot running status research summary exists on testing requirements, test method and test routine, this illustrates that existing release unit standard-required and test method can't guarantee effectively that the performance of release unit is qualified.
Summary of the invention
Purpose of the present invention, just provide a kind of supporting method of testing of lightning arrester that is applicable to the release unit performance, the situation of release unit tripping or malfunction can not occur by the release unit of this method of testing, satisfy the existing operating mode of installing the supporting performance requirement of lightning arrester with release unit.
When carrying out performance test with release unit to lightning arrester is supporting, tackle same type release unit in certain sequence step successively carry out, lightning arrester is supporting should not to move under continuous running voltage and during various superpotential with release unit, the ability that should have the tolerance various dash currents identical with lightning arrester, so should judge the mounting means confirmed test object of test product and supporting lightning arrester earlier, then apparently sound test product is optionally carried out mechanical robustness testing, leakage test or overcoat insulation resistance test or tolerable temperature cyclic test, then the test product by above examination is carried out dash current resistance test and the tolerance of little power current, ensuing test should embody release unit can be in time when (the power frequency fault current occurring) in supporting lightning arrester fault, accurately, action message, release unit should have good ampere-time characteristic, so last reply release unit carries out the acting characteristic test, after treating that above-mentioned a series of pilot project is finished, could estimate off-test to the type release unit performance.
Realize the foregoing invention purpose, the concrete steps of method of testing of the present invention are as follows successively:
The various test methods of the following stated are correspondingly carried out according to standard GB11032-2000 " interchange gapless metal-oxide lighting arrester ", JB/T8952-2005 " AC system composite sheath gapless metal-oxide lighting arrester " and DL/T864-2004 " nominal voltage be higher than 1000V exchange overhead transmission line use guide rule with composite insulator ", each test product all satisfies national standard and requires then to enter next step by test, otherwise judge that test product is all defective by the gross, end of test (EOT);
Step 1: prepare test, judge the mounting means of test product and supporting usefulness lightning arrester, if integral type then test product should be with and supportingly finish all pilot projects together with lightning arrester, if accessories type, then test product can be finished all pilot projects separately, prepares 15 test product numberings and is followed successively by T1～T15;
Step 2: check test product T1～T15 outward appearance, should be intact, otherwise off-test;
Step 3: the test product T1～T5 by above two steps is done mechanical robustness testing: install and normal user demand for satisfying, release unit should be able to satisfy national standard and require then to enter step 4 test routine continuation examination by axial 500N tension and normal direction 30Nm antitorque two aspects test;
Step 4: the test product T1～T5 by above three steps is done leakage test: test product is put into boiling water boil 42h, satisfy national standard and require then to enter step 7;
Step 5: the test product T6～T10 by step 1 and step 2 is made overcoat insulation resistance test: the overcoat insulation withstand voltage of release unit should satisfy national standard and require then to enter step 7 greater than the internal clearance sparking voltage;
Step 6: the test product T11～T15 by step 1 and step 2 is made the tolerable temperature cyclic test: examination sun direct projection and release unit overcoat tolerance performance under the environmental difference throughout the year, satisfy the national standard requirement and then enter step 7;
Step 7: to do the test of dash current resistance characteristics by step 4, five, test product T1～T15 of six: release unit should require identical with its matching used lightning arrester of institute, comprise tolerance 4/10us great current impact test, the test of 2ms rectangular impulse current and operating duty cycle test, test product all should reliably be failure to actuate, otherwise off-test;
Step 8: the test product T1～T15 by step 7 is done little power current resistance test; As power current effective value 20mA/2h resistance test, otherwise off-test;
Step 9: the test product T1～T15 by step 8 is done the acting characteristic test, and draw the ampere-second curve: the data of ampere-time characteristic curve should different symmetrical initial current levels be drawn by 3 of the test product of flowing through; To the system with effectively earthed neutral electric current is 20A, 200A and 800A power current effective value ± 10%, is 100mA, 1A and 20A power current effective value ± 10% to the electric current of system with non-effectively earthed neutral; To in three kinds of current values each, should test five test products at least;
Step 10: the performance of estimating above test product: if test according to above nine steps, test product can provide the effectively permanent obvious proof that breaks away from, then the test product performance is qualified, if the proof that test product can not be clear and definite, then should measure the electric current that flows through test product when test product applied 1.2 times/1min power-frequency voltage with the maximum rated voltage of the supporting lightning arrester of test product,, prove equally that then the test product performance is qualified if this electric current is no more than the 1mA effective value, simultaneously, off-test.
The invention has the beneficial effects as follows; the supporting performance test way of perfect lightning arrester with release unit; it is supporting with the deficiency on the release unit performance test methods at lightning arrester to have remedied existing standard; sound lightning arrester is supporting to have very strong directive function with the release unit testing standard to setting up, thereby has played the effect that well escorts to improving supporting lightning arrester, protection of arrester equipment and Operation of Electric Systems reliability.
