Monitoring device, bearing seat, air pump and transformer

Abstract

The invention provides a monitoring device, a bearing seat, an air pump and a transformer, the monitoring device is suitable for the bearing seat provided with a bearing, the monitoring device comprises: a controller, wherein the controller is electrically connected with a driving part used for driving a rotating shaft of the bearing to rotate so as to control the movement of the driving part; and a sensor which is arranged on the bearing seat, is electrically connected with the controller and is used for detecting the vibration quantity of the bearing seat and transmitting a detection signal to the controller. The controller compares the vibration quantity of the detection signal with a preset vibration quantity range so as to judge that the bearing breaks down when the vibration quantity of the detection signal is not within the preset vibration quantity range and control the driving part to stop moving. The monitoring device solves the problem that no device for monitoring the state of the bearing of the gas pump for providing gas for the gas transformer exists in the prior art.

Description

technical field [0001] The invention relates to the field of bearing state monitoring, in particular to a monitoring device, a bearing seat, an air pump and a transformer. Background technique [0002] Gas transformers are mainly suitable for high-rise buildings, underground, restricted by site, densely populated areas with high fire protection and explosion-proof requirements to ensure safety, etc. It has little pollution to the environment and strong overload capacity, and has absolute advantages in certain places. . Gas insulated transformer is a transformer with SF6 gas as the insulating medium. Its English name is GAS INSULATORTRANSFORMERS, or GIT for short. SF6 gas has excellent insulating properties, non-combustibility and good environmental performance, it can replace transformer oil in transformers. Since the first SF6 insulating transformer was produced in 1967, due to the advantages of SF6 insulating transformer in non-combustibility, insulation and safety, it h...
