AI Technical Summary
Technical Problem
The existing pressure relief device frequently switches on and off when the air pressure inside the switchgear changes, which damages the device and affects the pressure relief effect.
Method used
A primary buffer assembly and a secondary buffer assembly are installed on the top cover of the switch cabinet. The cover is slowly closed through vent holes and a buffer tube structure to mitigate changes in air pressure.
Benefits of technology
It improves the pressure relief effect, reduces device wear, and extends the service life of the pressure relief device.
