Problems solved by technology

[0003] As the voltage level of the produced vacuum interrupter is upgraded from 35kV and below to 72.5kV and 126kV, the original liquid medium (transformer oil, etc.) can no longer meet the production requirements
In order to ensure production and product quality, we have introduced an inflatable high-voltage aging system; since this system is a closed system, it is necessary to connect the wires before closing the cover, the power cord is in a slack state, and part of the power cord is suspended in the Around the vacuum interrupter in the aging system, the distribution state of the electric field in the aging system is changed, affecting the aging effect of the vacuum interrupter, and in severe cases, it will cause the breakdown of the vacuum interrupter

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0015] Embodiments of the present invention: a high-voltage aging system for vacuum interrupters, as attached Figure 1-3 As shown, there is an aging system 10. The interior of the aging system 10 is a hollow structure. The aging system 10 is provided with a vacuum interrupter 9 and a wire-8. When aging, one end of the wire-8 is connected to the vacuum placed in the aging system The top of the arc extinguishing chamber 9 is connected, and the other end is connected to a wire 2 6 after passing through the cover plate on the top of the seasoning system (10). An automatic wire take-up mechanism 7 is arranged between the cover plates on the top, and the wire 18 is wound on the automatic wire take-up mechanism 7. When it is mature, the automatic wire take-up mechanism 7 will take the redundant wire 1-8 i...

Abstract

The invention discloses a vacuum extinction chamber high voltage aging system. The system comprises an aging system (10). The aging system (10) is internally provided with a vacuum extinction chamber (9) and a wire I (8). One end of the wire I (8) is connected with the upper end of the vacuum extinction chamber (9), and the other end thereof passes through a cover plate at the top of the aging system (10) and then is connected with a high voltage power supply generator through a wire II (6). An automatic wire take-up mechanism (7) is arranged between the wire I (8) and the cover plate at the top of the aging system (10). The vacuum extinction chamber high voltage aging system has the beneficial effects that the wire is taken up automatically, an electric field in the aging system is distributed stably, the aging effect is good, the structure is simple, and the design is reasonable.

Description

technical field [0001] The invention relates to an aging system, in particular to a high-voltage aging system for a vacuum interrupter. Background technique [0002] Vacuum switches are widely used in the medium voltage field due to their small size, long life, reliable short-circuit current breaking, and maintenance-free or less maintenance. In the production of the vacuum interrupter, the voltage aging process is widely used, the purpose of which is to eliminate the burr inside the interrupter, the metal and non-metallic particles on the working surface of the contact, and various dirt. In the traditional mature system, in order to adapt to different environments, the length of the high-voltage power line connecting the high-voltage power supply and the mature system is usually long. When the distance between the high-voltage power supply and the mature system is short, the power line is in a slack state, but the system It is open, and the tension of the power cord can be...
