Abstract

The invention discloses a gas insulated metal tip defect device for a partial discharge test under impact voltage. The gas insulated metal tip defect device is characterized by comprising an upper aluminum pole plate and a lower aluminum pole plate, wherein a synthetic glass tube is arranged between the upper aluminum pole plate and the lower aluminum pole plate, the synthetic glass tube, and the upper aluminum pole plate and the lower aluminum pole plate form a cylindrical chamber together, an internal simulation defect dimension is adjusted through threaded connection of an adjustable guide rod and the upper aluminum pole plate, a metal tip electrode is connected with the guide rod through a screw, and a gas charging and discharging device is mounted at one side of the lower aluminum plate and is used for realizing gas charging and discharging of the cylindrical chamber. The gas insulated metal tip defect device and a partial discharge test system under impact voltage shorten test time and are convenient and fast to research.

Description

technical field [0001] The invention relates to a gas-insulated combined electrical appliance, in particular to a gas-insulated metal tip defect device for a partial discharge test under an impulse voltage and a partial discharge test system under an impulse voltage, belonging to the technical field of gas-insulated switchgear. Background technique [0002] Gas insulated switchgear (Gaslnsulated Switchgear, GIS) is one of the important components of the UHV power grid. After optimized design, the inlet and outlet bushings are respectively installed in their respective sealed rooms, and finally assembled in a whole shell filled with SF6 as the insulating medium. [0003] Defects inside GIS that affect the performance of insulating media mainly include: serious installation errors, poor contact between conductors, high-voltage conductor protrusions, fixed particles, insulator defects, steam, etc. [0004] With the increase of power grid voltage in my country, more and more at...
