An anti-vibration type low-voltage fixed switch cabinet

Abstract

The invention discloses an anti-vibration type low-voltage fixed switch cabinet, An anti-vibration bearing is symmetrically arranged at four corners of the outer end face of the bottom wall of the switch cabinet, the anti-vibration bearing comprises an upper anti-vibration bearing part and a lower anti-vibration bearing part, the upper anti-vibration bearing part comprises an upper anti-vibrationbearing, a plurality of first blind holes are arranged at the edge of the bottom face of the upper anti-vibration bearing, and a plurality of first pillars are arranged at the side faces of the upperanti-vibration bearing; A low vibration bearing component include a lower vibration bearing, A low vibration bearing is provide with a first groove in that middle of the top surface, A plurality of second pillars are integrally arranged on the bottom surface of the first groove, a first spring is fixed between the top end of the second pillar and the top end of the corresponding first blind hole,a second spring is fixed between the upper side surface of the second pillar and the side surface of the first blind hole, a third spring is sleeved on the second pillar, a plurality of second groovesare arranged on the side surface of the first groove, and a fourth spring is sleeved on the first pillar. The invention can not only carry out vertical stress buffer and deformation adjustment, but can also carry out horizontal stress buffer and deformation adjustment, and has a better effect.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to an anti-seismic low-voltage fixed switchgear. Background technique [0002] Switchgear refers to the equipment used for on-off, control or protection in the process of power system power generation, power transmission, power distribution, power conversion, etc. [0003] In the anti-seismic fixed switchgear in the prior art, only vertical springs are provided between the switchgear main body and the base, so that when an earthquake occurs, the switchgear main body and the base can only realize vertical stress buffering and deformation adjustment, while Horizontal stress buffering and deformation adjustment cannot be performed. Since the vertical spring needs to bear the gravity of the main body of the switchgear for a long time, elastic fatigue is prone to occur after long-term use, which leads to a greatly reduced shock absorption effect. In the existing technology...

Problems solved by technology

[0003] In the anti-seismic fixed switchgear in the prior art, only vertical springs are provided between the switchgear main body and the base, so that when an earthquake occurs, the switchgear main body and the base can only realize vertical stress buffering and deformation adjustment, and the Horizontal stress buffering and deformation adjustment cannot be performed. Since the vertical spring needs to withstand the gravity of the main body of the switchgear for a long time, elastic fatigue is prone to occur after long-term use, which leads to a greatly reduced shock absorption effect. In the existing technology, in order to replace the vertical spring , is to set the screw rod in the base, by turning the screw rod to make the screw rod support the main body of the switch cabinet, and then replace the vertical spring, but because the gravity of the main body of the switch cabinet is relatively large, it will require a large force to make the screw rod Support the main body of the switchgear

[0004] Another anti-seismic fixed switchgear in the prior art has a horizontal spring between the main body of the switchgear and the base, but there is no guide bar on the horizontal spring, so the horizontal spring is more likely to be damaged, and some of the horizontal springs are damaged. Under the long-term gravity of the switch cabinet, the horizontal spring is prone to elastic fatigue after long-term use. When replacing the horizontal spring, the entire shock-absorbing support must be replaced
