Multi-stage highly-efficient damping pedestal for box type transformer station

Abstract

The invention provides a multi-stage high-efficiency shock-absorbing base for a box-type substation, which includes an upper support plate, a lower support plate and a concrete facade, and a horizontal shock-absorbing device and a longitudinal shock-absorbing device are fixedly installed on the sides of the lower support plate. The bottom of the lower support plate is fixedly connected with rollers, and the rollers are slidably connected with the chute, and the chute is fixedly connected with the oil pressure shock absorber, and the oil pressure shock absorber is fixedly connected with the concrete facade through anchor bolts. The present invention The structure is simple, the box-type substation can be supported by the oil pressure shock absorber, and the vertical vibration of the box-type substation due to external force can be absorbed and buffered, and the box-type substation can be absorbed and buffered Due to the lateral and longitudinal vibrations generated by external forces, the loss of internal equipment in the box-type substation is reduced, and the safety factor of the box-type substation is improved.

Description

technical field [0001] The invention relates to the technical field of box-type substations, in particular to a multi-stage high-efficiency shock-absorbing base for box-type substations. Background technique [0002] Existing box-type substations are all placed outdoors, and the outdoor environment is harsher than indoors, and is easily impacted by external forces to cause damage to the electrical equipment in the box. [0003] The Chinese patent with the application number "201620910862.2" discloses a box-type substation shock-absorbing base. The box-type substation shock-absorbing base includes an upper support plate and a lower support plate. The upper support plate and the lower support plate are set There are rubber buffer plates, hemispherical airbags are staggeredly arranged on the opposite surfaces of the rubber buffer plates, and hydraulic shock absorbing rods with shock absorbing springs are set on the edges of the opposite faces of the upper support plate and the ...

AI Technical Summary

Problems solved by technology

[0004] 1. Through the design of damping spring, hydraulic damping rod and air bag, this patent can only absorb the longitudinal vibration of box-type substation due to external force, but cannot absorb the lateral vibration caused by external force;

[0005] 2. There is no sealing structure between the upper support plate and the ground in this patent, and foreign matter from the outside can easily enter the inside of the base;

[0007] 4. The patent uses the airbag as a shock-absorbing buffer structure. Since the service life of the airbag is generally not long, the patent requires frequent replacement of the airbag, which is complicated and inconvenient to operate.
