Abstract

A high-repeatability standard creeping discharge model device is characterized by comprising an organic glass round tube (5), the upper end and the lower end of the round tube (5) are sealed through an upper end cover (4) and a lower end cover (9) respectively, ventilation holes (2) are formed in the periphery of the upper end cover (4), a high-voltage electrode (3) is connected with the middle of the upper end cover (4) through threads, a tungsten needle (6) is arranged below the high-voltage electrode, a grounding electrode (8) is arranged in the middle of the lower end cover, a crystal ball (7) adheres to the grounding electrode with sealing glue, and a discharge gap is reserved between the tungsten needle and the crystal ball. Practical tests show that the discharge model device is small in discharge capacity, stable in discharge and good in repeatability.

Description

technical field [0001] The invention relates to a gas discharge device in the technical field of high voltage insulation. Background technique [0002] The GIS partial discharge UHF online monitoring system needs to develop a standard discharge model according to various discharge types inside the GIS, especially for the calibration of the on-site online monitoring system. A standard discharge source with stable amplitude and constant transmission power is an essential device. The existing creeping discharge model is relatively rough, there is no unified technical standard, and there are problems such as large discharge volume, unstable discharge, and poor repeatability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high repeatability standard creeping discharge model device. [0004] To solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follow...
