Problems solved by technology

This solution reduces the volume of the device to a certain extent, but the oil-immersed design also greatly increases the weight of the test device; moreover, the device uses a conventional single-ended capacitor, and the insulation distance at the end limits the voltage level of the capacitor body , leading to an increase in the number of capacitors and other components required for the same level of shock generating devices, and increased installation complexity

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0016] An example provided by the present invention is an integrated, fully enclosed, compact enclosed gas-insulated impulse voltage generating device filled with sulfur hexafluoride gas. The device uses sulfur hexafluoride gas with good insulation performance as the main insulating medium, so the size of each device and the insulation distance between devices can be greatly shortened, thereby reducing the volume and weight of the impact generating device, which is beneficial to the installation and operation of the test device. Lifting, etc., improve the work efficiency of the field test and reduce the requirements for the equipment installation space in the test hall.

[0017] Figure 1~3 It is a structural schematic diagram of a compact closed gas-insulated impulse voltage generating device of an example of the present invention, which inclu...

Abstract

The invention discloses a compact closed gas insulation impulse voltage generation device. The compact closed gas insulation impulse voltage generation device comprises a charging device and a wave modulation device and further comprises a sealed insulation shell, a frame type insulation support, a first shed insulator, a second shed insulator, a fifth shed insulator and a gas insulation multilevel impulse voltage generator, wherein the gas insulation multilevel impulse voltage generator is fixed in the sealed insulation shell through the frame type insulation support, the sealed insulation shell is provided with an inflation and deflation port, and the sealed insulation shell is grounded. The size and weight of the device can be reduced effectively, and the compact closed gas insulation impulse voltage generation device can adapt to a field test of ultrahigh / extra-high voltage substation equipment.

Description

technical field [0001] The invention relates to the technical field of high-voltage testing and insulation, in particular to a compact closed-type gas-insulated impulse voltage generating device. Background technique [0002] In the prior art, the impulse voltage generator generally adopts an ordinary open type, and the impulse test voltage is output through the high-voltage lead-out bushing and the overhead busbar. However, because this kind of generating device uses air with poor insulation as the main insulating medium, it is bulky, the cost of separate transportation is high, and the workload of on-site installation is large, so it is not easy to carry out the on-site insulation characteristic test of substation equipment. Because the device is exposed to the air, it is greatly affected by the external environment such as air pressure, temperature and humidity, and is prone to failure. [0003] The Chinese invention patent with publication number CN103308736A provides a...
