Description

GIS casing with shock resistance Technical Field The utility model relates to the technical field of GIS shells, in particular to a GIS shell with shock resistance. Background The GIS housing is a housing for protecting GIS devices, and is mainly used for protecting the devices from the interference and damage of the external environment. The GIS shell is widely applied to industries such as power, communication, traffic, petrochemical industry and the like, and is an important component for ensuring normal operation of equipment. The need for use in harsh environments makes the housing desirable for good shock resistance. At present, an anti-vibration base is usually arranged between a shell and a base, and is usually made of elastic materials such as a spring, a hydraulic component or rubber, buffering is achieved by converting impact force acting on the shell into elastic potential energy, but when the shell vibrates, the internal equipment is driven to vibrate reciprocally, the GIS equipment has larger mass, the upper part and the lower part of the shell are deformed due to long-term vibration, gaps are formed at the connecting positions, and finally high-pressure gas in the shell is leaked. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a GIS shell with shock resistance.
