Air cushion type buffer device, extra-high voltage generator and vertical lifting method

Abstract

The invention discloses an air cushion type buffer device, an extra-high voltage generator and a vertical lifting method, and belongs to the technical field of extra-high voltage generator equipment. An existing extra-high voltage generator can bear large impact force in the overturning process, so that internal components are prone to damage, and meanwhile the use precision of the existing extra-high voltage generator can be affected. The air cushion type buffer device for vertical lifting comprises an air cushion body used for abutting against equipment to be turned over and an inflation source used for inflating the air cushion body. The air cushion body is provided with an inflation valve port used for inward air inflow and an air outlet hole used for outward air exhaust. The air cushion body abutting against the equipment to be overturned is arranged, delaying and buffering can be conducted on vertical lifting of the equipment to be overturned, meanwhile, the air outlet holes capable of exhausting air outwards are formed, when the air cushion body is subjected to extrusion force exceeding a set value, air can be exhausted outwards through the air outlet holes, and it is ensured that the equipment to be overturned can be slowly lifted; and therefore, the components of the equipment to be overturned can be effectively protected.

Description

technical field [0001] The invention relates to an air cushion type buffer device, a UHV generator and a vertical lifting method, and belongs to the technical field of UHV generator equipment. Background technique [0002] In the DC high-voltage field experiment, the equipment is generally large and heavy, and it needs to rely on the crane to assist the operation. The labor intensity of the on-site staff is high and the efficiency is low. Therefore, integrating the equipment on one platform can significantly improve the efficiency of on-site experiments. However, the UHV generator equipment is generally relatively high. For the convenience of transportation, it is usually laid down. After arriving at the site, it is lifted up by a hydraulic mechanism. Put it down when the experiment is over. [0003] However, the ultra-high voltage generator is equipped with high-voltage silicon stacks and other components inside. The high-voltage silicon stacks are generally composed of mu...

Problems solved by technology

[0003] However, the ultra-high voltage generator is equipped with high-voltage silicon stacks and other components inside. The high-voltage silicon stacks are generally composed of multiple silicon diodes in series. The components are relatively precise. When subjected to excessive impact or repeated vibration, the components are easy damage, which will affect the accuracy of its use

[0004] Furthermore, the casing of the ultra-high voltage generator is generally made of non-metallic materials, which cannot withstand excessive impacts. Under repeated vibrations, it is easy to damage and affect its service life
