Experimental Research on Vibration and Noise Reduction of Vehicular Vacuum Circuit Breaker's Equipment Box

摘要

Through the test method of bench test, the vibration and noise condition of vehicle vacuum circuit breaker equipment box is analyzed under several measures for vibration and noise reduction, which provides important basis for vibration and noise reduction and low noise design of this device. The experimental results show that the damping effect is not obvious when adding the damping washer between the installation panel of main circuit breaker and the installation box girder. Adding vibration isolation sponge and rubber shock absorber on the contact surface between the platform and the box has a certain effect on alleviating the vibration of the bench and reducing the noise at the bottom of the box, and the effect of vibration and noise reduction from shock absorber is better compared with the vibration isolation sponge.
