Abstract

The invention discloses a direct-current high-voltage generator testing device and a testing method thereof, which are used for testing a double-section lightning arrester structure. The device comprises a high-voltage generator, a console, a first current detector and a second current detector, and the console is connected with the high-voltage generator; the output end of the high-voltage generator is connected with the first current detector in series; the output end of the first current detector is connected with a lightning arrester structure; a first porcelain bottle and a second porcelain bottle of the lightning arrester are connected in series, the second end of the first porcelain bottle is connected with the first end of the second porcelain bottle, the first end of the first porcelain bottle is grounded, the second end of the second porcelain bottle is connected with the input end of a second current detector, and the output end of the second current detector is grounded. The invention further provides a direct-current high-voltage generator testing method. According to the invention, the direct-current reference voltage and leakage current tests can be carried out on lightning arresters of various voltage classes without removing wires, and the wiring is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of high-voltage generators, in particular to a test device for a DC high-voltage generator and a test method thereof. It is mainly used in the DC reference voltage of the zinc oxide arrester at 1mA and the leakage current at 75% of the reference voltage in the zinc oxide arrester power failure test project. Background technique [0002] Due to its good nonlinear volt-ampere characteristics, zinc oxide arresters have been widely used in power systems. At present, in the routine power failure test of AC zinc oxide arresters, the most important test items are the reference voltage at DC 1mA and 75 % Leakage current test under this reference voltage, according to the maintenance guidelines in the "Condition Maintenance Test Regulations for Power Transmission and Transformation Equipment" (Q / GDW 1168-2013), the test method of not removing the lead wire should be adopted for the power failure test of 500kV and abo...
