A shock absorbing device and a shock absorbing method for an electric control box

Abstract

The invention discloses a shock absorbing device and a shock absorbing method for an electric control box. The shock absorbing device includes an electronically controlled shock absorbing damper, a vibration detector, an anti-shock airbag, and a shock absorbing control unit, and the electrically controlled shock absorbing damper, the vibration detector and the shockproof airbag are all arranged on the installation surface of the electric control box, and The vibration measuring device is connected with the electronically controlled shock-absorbing damper, and the shock-absorbing control unit is arranged in the electric control box, and can control the opening of the anti-shock airbag and control the electric-controlled shock-absorbing damper to generate damping. The shock absorption method includes that the vibration parameter obtained by the vibrator is less than the first preset value, and the electronically controlled shock absorbing damper is in a natural elastic state; the vibration parameter is greater than the first preset value but less than the second preset value, and the electronically controlled shock absorbing damper Enter the non-elastic state; the vibration parameter is greater than the second preset value, and the anti-vibration airbag is opened. According to the external vibration intensity, the invention successively controls the opening of the electronically controlled shock-absorbing damper and the shock-proof airbag, adopts double shock-absorbing, good shock-resistant performance, and prolongs the service life.

Description

technical field [0001] The invention relates to power distribution equipment, in particular to a shock absorbing device and a shock absorbing method for an electric control box. Background technique [0002] A distribution switch box is a device that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal shell according to electrical wiring requirements. During normal operation, the control circuit can be switched on or off by means of manual or automatic switches. The distribution switch box has the characteristics of small size, easy installation, unique configuration function, no site restrictions, common application, stable and reliable operation, high space utilization, and small footprint. Generally, the distribution switch box is in rigid contact with the ground or the foundation. When the external vibration or the machine tool is running, the whole box will follow the vibration, and the internal ...

AI Technical Summary

Problems solved by technology

Generally, the power distribution switch box is in rigid contact with the ground or the foundation. When the external vibration or the machine tool is running, the whole box will follow the vibration, and the internal important components and instruments will also follow the vibration, resulting in loose fastening in the distribution box and causing performance failure. Serious The equipment is burned out in time, causing heavy losses of property and personnel
