Problems solved by technology

On the one hand, it is very labor-intensive to set up scaffolding and transport the radiator, and it is not easy to connect the power supply at a high place. On the other hand, placing the radiator on the scaffold can only dissipate heat vertically, and it is impossible to accurately cool down the angled equipment.

Description

technical field [0001] The invention relates to the field of substation equipment maintenance, in particular to a hydraulic mobile fan lifting support. Background technique [0002] At present, with the rapid development of my country's economy, the power load continues to rise, and a large number of high-voltage direct current transmission projects have been put into operation. During the peak period of electricity consumption, the power grid equipment has been in high-load operation for a long time, and some equipment is prone to overheating, which increases the probability of equipment failure. Overheating of equipment will cause failure or even tripping, and serious fire will occur. The auxiliary heat dissipation capacity of the system has been tested, and it also poses a threat to the safety and stability of the power grid. [0003] When the power transmission and transformation equipment in the converter station is running at high load, there will be situations where ...
