Abstract

The invention discloses a vacuum degree real-time monitoring device for vacuumizing operation. The problem that the vacuum degree of an air chamber cannot be accurately monitored in real time in the prior art is solved. The device comprises an adapter, wherein a GIS air chamber is directly connected with a vacuum pump unit through the adapter; a standard gas chamber special joint, used for connecting a gas outlet of the GIS gas chamber with a vacuum pipeline of the vacuum pump unit; and an electronic vacuum meter, arranged on the adapter and used for monitoring the vacuum degree of the GIS airchamber. The monitoring device replaces an original mode that the pressure in the air chamber is observed through a vacuum meter on the vacuum pump unit, measurement errors caused by pipeline pressure difference are eliminated, unnecessary vacuumizing time is shortened, and vacuumizing operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of vacuum degree detection, in particular to a real-time monitoring device for vacuum degree in vacuuming operation. Background technique [0002] The overhaul of GIS equipment requires vacuuming the equipment, and the vacuuming operation time often occupies a considerable part of the entire construction period. Since the vacuuming process is uninterrupted, maintenance personnel are required to monitor it, which consumes a lot of manpower and material resources. When using a vacuum pump to perform the vacuum tube operation on the GIS, because the vacuum gauge is far away from the gas chamber, it is impossible to accurately monitor the internal pressure of the gas chamber. During the operation, a part of the time is often spent based on experience to ensure that the internal pressure of the gas chamber reaches the standard, which causes time. and waste of manpower and material resources. [0003] For example, a "GIS e...
