Description

technical field

[0001] The invention relates to a transport trolley, in particular to an adjustable transport trolley for transporting the arc extinguishing chamber of a horizontal circuit breaker into the shell and adjusting to the required height to facilitate the installation of the arc extinguishing chamber. Background technique

[0002] At present, most 220kV GIS circuit breakers are of horizontal structure. After the arc extinguishing chamber is assembled, it needs to be put into the circuit breaker housing horizontally, and it cannot be hoisted at this time. However, when the arc extinguishing chamber is assembled, it needs to be lifted to a certain height and fixed with the circuit breaker housing.

[0003] In order to solve the above problems, there is a method of using rubber pads as temporary support in the industry. This method is not easy to operate, and improper operation may easily cause damage to the arc extinguishing chamber. There is also a method of using...
