Description

Installation method of switchgear in substation substation distribution room

technical field

The invention relates to the field of mechanical technology, in particular to a method for installing a switchgear in a substation power distribution room.

The switchgear used in the substation is used to perform switching, control and protection of electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The switchgear in the substation is an important equipment in the substation. Generally speaking, the switchgear used in the substation is relatively large and difficult to carry manually.

Generally speaking, in order to ensure the progress of the project, during the construction of a new substation, the equipment installation is carried out simultaneously with the civil engineering. It is often encountered that the equipment needs to be installed when the road surface is not completed or fully hardened.

In the prior art, when installing the switchgear in the substation and distribution room when the road surface is not completed or fully hardened, it is generally necessary to use a crane to lift the switchgear in the substation and distribution room from the trailer or unloading position to the entrance of the distribution room. Then, the switch cabinet in the substation and distribution room is sent into the power distribution room. At this time, the switch cabinet is generally placed on a simple support made of sleepers, and then the switch cabinet is pushed into the substation and distribution room by manpower. Using this method to install the switchgear in the substation and distribution room, on the one hand, the labor cost is high, and the installation speed is slow due to the laying of simple brackets. On the other hand, due to the heavy weight of the switchgear, there is a high risk when the simple support carries heavy objects, which may easily lead to production accidents such as casualties or property losses.

Therefore, how to effectively improve the convenience and safety of switchgear installation in substation substation distribution room has become an urgent problem to be solved.
