Description
[technical field]
The utility model relates to direct current arrester experimental technique field, particularly a kind of test unit in the type approval test of a kind of composite sheath direct current arrester.
[background technology]
At present, AC system is passed through long-term development with polymeric housed metal oxide arrester, the anti-galvanic corrosion of its lightning arrester and full skirt overcoat undermines the creepage trace performance have been had and has significantly improved, and is used for simultaneously check lightning arrester and the anti-galvanic corrosion of full skirt overcoat and undermines also corresponding foundation of the various test methods of creepage trace performance and standard.Yet all adopt ac high voltage in these test methods and the standard, and there are significant difference in alternating current arc and direct-current arc performance, direct-current arc is more harsh.Therefore directly anti-galvanic corrosion undermines the creepage trace method and standard is evaluated the anti-electric traceization of direct current arrester and the performance of deteriorating is very not rational to exchange.
According to the requirement of GB/T 22389-2008 " HVDC converter substation gapless metal-oxide lighting arrester guide rule " with GB/T25083-2010 " ± 800kV straight-flow system metal oxide arrester " standard, " the anti-electric traceization of lightning arrester overcoat and the test of deteriorating " in the direct current arrester type approval test become an important performance assessment criteria of composite sheath direct current arrester.
[utility model content]
The purpose of this utility model provides the anti-electric traceization of a kind of composite sheath direct current arrester and the test unit that deteriorates, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
