摘要

According to an embodiment of the present invention, in the switchgear provided with the earthquake detection device and the seismic device The main body of the switchgear, the earthquake detection device installed in the main body of the switchgear, It is composed of a seismic device equipped with a seismic displacement detection sensor that is mounted on the main body of the switchgear and protects the main body of the switchboard from impacts such as earthquakes. The upper-handed earthquake detection device consists of a control MPU, an acceleration sensor, a display device, an earthquake level setting part, an earthquake detection trip coil output part, an RTC, a communication, a power supply part, and a trip coil operation calculation part. The seismic device provided with a seismic displacement detection sensor includes an upper housing; A lower housing fixed to face the upper housing to form an inner space together with the upper housing; A vibration-proof spring located at the center of the inner space and fixed to the upper and lower housings to absorb external shocks in the vertical direction; First to fourth leaf springs located on both sides of the anti-vibration spring in the inner space, and having elastic bent portions convexly curved in the direction of the anti-vibration spring; Fifth and sixth leaf springs located on both sides of the vibration-proof spring in the inner space and having elastic curved portions convexly curved from the lower housing toward the upper housing; First and second sub-vibration isolating springs respectively positioned under the elastic curved portions of the fifth and sixth leaf springs; A plurality of assembly bolts and nuts for assembling the upper and lower housings, the anti-vibration spring, the first to sixth leaf springs, and the first and second sub anti-vibration springs; And a seismic displacement detection sensor for sensing an external shock applied to the seismic device.
