Description

Technical Field

[0001] The utility model relates to the technical field of cable hook cover plate construction, in particular to a cable trench cover plate for a transformer substation which is easy to lift. Background Art

[0002] A substation is a place where voltage is changed. In order to transmit the electricity generated by a power plant to a distant place, the voltage must be increased to high voltage, and then the voltage must be lowered as needed near the user. This work of raising and lowering the voltage must be completed by the substation, so the power supply task undertaken by the substation is a vital link in the power grid.

[0003] In order to ensure the stable operation of the equipment and facilities of the entire station, the substation must conduct a firewall inspection every month, and the cable trench must be checked and cleaned every quarter. During each inspection, a large number of cable trench covers must be lifted. Since there are no handles on the covers, it is very difficult to lift the covers. Each time the covers are lifted, two people are required to work together, and they can only use crowbars, hand lifting and other methods, relying entirely on brute force to lift. Not only is it easy to cause hand injuries to the operators, but the workers are also time-consuming and laborious when lifting the cable trench covers, which seriously affects the work progress and poses a safety hazard. Therefore, we proposed a substation cable trench cover that is easy to lift, so as to solve the above-mentioned problems. Utility Model Content
