Abstract

The invention discloses a portable DC test discharge rod, relates to a discharge device used in an electric property testing process and is used for solving a problem of susceptibility of length change of a prior electricity testing rod due to external interference. The portable DC test discharge rod includes a telescopic insulation body comprising a bottom sleeve, a middle sleeve and an upper sleeve. A spiral screw rod having a length equal to that of the bottom sleeve is arranged in the bottom sleeve. A hollow connection rod having a length equal to that of the middle sleeve is arranged in the middle sleeve. A hollow screw rod having a length equal to that of the upper sleeve is arranged in the upper sleeve. The spiral screw rod is provided with male threads. The hollow screw rod is provided with female threads. The inner surface and the outer surface of the hollow connection rod are both provided with threads. The threads on the inner surface of the hollow connection rod cooperate with the male threads of the spiral screw rods. The male threads of the hollow connection rod cooperate with the female threads of the hollow screw rod. The portable DC test discharge rod is applied toDC voltage withstanding tests and releases electric charges accumulated on a test sample.

Description

technical field [0001] The invention relates to a discharge device used in the process of electrical performance testing, in particular to a portable DC test discharge rod. Background technique [0002] The DC discharge rod is used in various outdoor high-voltage tests, especially in the DC withstand voltage test, to release the charge accumulated on the test object to ensure personal safety. It is an indispensable tool for the withstand voltage test. The existing DC discharge rods can be shrunk, small in size, light in weight, easy to carry, safe and reliable. The length of the discharge will be changed due to jitter or other disturbances, which will affect the discharge process and even pose a threat to personal safety. Contents of the invention [0003] In order to solve the above problems, the present invention provides a portable DC test discharge rod that can be stretched and is not susceptible to changes in the stretching length caused by external interference duri...
