Abstract

The invention discloses a rainproof cap, which comprises: a hoop assembly, a rainproof cover connected with the hoop assembly, and an elastic screen arranged on the rainproof cover; the elastic screen and the The hoop component is located on the same side of the rainproof cover, and the elastic mesh is a wavy elastic mesh or a zigzag elastic mesh. The rainproof cap of the present invention can be applied to old and new main transformers without dismantling any flange bolts. Rain demand, high versatility, elegant appearance, and has the effect of preventing birds from building nests.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a rain cap. Background technique [0002] The Buchholz relay of the transformer is the main protection component for the internal fault of the transformer. Once the secondary junction box of the Buchholz relay enters the water, it will cause the main transformer to trip by mistake and affect the reliability of the power supply. Therefore, it is necessary to install a rain cover for the Buchholz relay. There are three types of rain covers for main transformer gas relays, which are heat shrinkable rain covers, customized stainless steel rain covers, and universal stainless steel rain covers. The three types of existing rain cover have shortcomings respectively. The heat shrinkable rain cover is usually fastened with plastic carding or plastic rolling tape, which is very easy to age, causing the rain cover to loosen or fall off; When the gas function is used, it is necessar...
