Abstract

The invention provides a portable GIS equipment insulation listening barrel, and relates to a monitoring tool for monitoring the sound of GIS equipment. The portable GIS equipment insulation listening barrel comprises a sucker type listening head, a barrel body, a sound guide tube and an ear piece. The operation personnel can correctly judge whether the equipment runs normally or not even with the presence of ambient noises. Meanwhile, the ears of the operation personnel are not required to directly approach the body of the equipment, so that the risk of electric shocks is reduced for the operation personnel.

Description

technical field [0001] The invention relates to the technical field of detection tools for GIS equipment, and more particularly, relates to a portable GIS equipment insulation listening earpiece. Background technique [0002] With the increasing service life of GIS equipment, various defects will gradually increase. Operators need to monitor the operating conditions of GIS. During the operation of GIS equipment, if there is an abnormality, various sounds will be emitted inside, and vibrations of different degrees will occur. After mastering certain rules, we can judge the fault of the equipment from the change of sound and the strength of vibration. However, at this stage, substation operators lack monitoring tools for the sound of GIS equipment in daily inspection and maintenance work, and only rely on ears or touch with hands to check by feeling. However, GIS equipment is a closed equipment. When the internal parts are loose or there is a discharge sound, it is not easy ...
