Abstract

The invention belongs to the field of electric power, and particularly relates to a universal change-over switch detection method. The method is carried out in cooperation with a universal change-over switch detection device, the universal change-over switch detection device comprises a connecting transverse plate, connecting transverse plate installation sliding grooves are formed in the connecting transverse plate, and an upper machine shell installation sliding block which can freely slide and can be pulled out of a connecting transverse plate installation opening is arranged in each connecting transverse plate installation sliding groove. An upper machine shell is fixedly arranged on the upper machine shell installation sliding block, an exhaust device is arranged on the upper portion of the upper machine shell, an air pressure detection device capable of detecting the air pressure of an inner cavity of the upper machine shell is arranged on the inner wall of the upper machine shell, sealing mechanisms are arranged on the upper machine shell and the connecting transverse plate, an inner machine shell is fixedly arranged on the lower end face of the connecting transverse plate, and clamping mechanisms are symmetrically arranged on the inner wall of the inner machine shell. An air inlet mechanism is arranged at the lower end of the inner machine shell, an outer machine shell covering the inner machine shell is fixedly arranged on the lower end face of the connecting transverse plate, a bottom machine shell inlet is formed in the lower portion of the outer machine shell, and an air purifying mechanism capable of purifying air entering from the bottom machine shell inlet is fixedly arranged on the lower portion of the outer machine shell.

Description

technical field [0001] The invention belongs to the field of electric power, and in particular relates to a detection method for a universal transfer switch. Background technique [0002] The universal transfer switch is a switch widely used in power control systems. Due to its own mechanism characteristics, it has high requirements for the working environment, not only to avoid the entry of dust, but also to avoid the entry of other possible combustibles, so certain requirements are put forward for the airtightness of its shell. Most of the existing technologies are to add additional protective devices on it, or change the wiring method to protect its airtightness, and it is impossible to test whether its airtightness meets the requirements before installation, and there is no technology for pre-cleaning it . To sum up, this design requires an additional mechanism to realize the detection and pre-cleaning method of the universal transfer switch before installation. Cont...
