Abstract
Description
Technical Field
[0001] The utility model relates to an electrical device, in particular to a box-type transformer substation top cover. Background Art
[0002] The top cover of a box-type substation is usually made of multiple plates due to its large area. The traditional splicing scheme is usually to add a cover plate after welding, and finally apply sealant on the outer periphery of the cover plate. The traditional process requires spot welding and then full welding. The cover plate is welded to the top cover by full welding. If the full welding process is not adopted, it is necessary to fill all the connection gaps with sealant. Since the design service life of a box-type substation is usually more than 25 years, the sealant is prone to aging after long-term exposure to the sun and low temperature, and the filling capacity of the gap is reduced. The rainwater cannot flow down quickly and easily produces a siphon effect at the gap, sucking the rainwater into the box-type substation, causing equipment failure or even burning; although the full welding process can avoid the above situation, it has high requirements on the process level and operators, and the processing time is long and the efficiency is low.
