Problems solved by technology

A large amount of oxides will also be generated at the contact part of the rain cover and the conductive rod. In severe cases, the two will be integrated, corroding the contact part, and greatly reducing the current-carrying capacity of the conductive copper rod.
[0005] 2. Difficult to disassemble
Since the rainproof cover is difficult to dismantle, it is bound to waste a lot of time on the removal of the rainproof cover in order to complete the disassembly and maintenance of the entire conductive rod without damaging the ra

Abstract

The invention discloses an isolating switch contact rainproof cover device which is easy to disassemble and easy to repair. It is characterized in that it includes a conductive rod, a fixed base, and a rainproof cover. The right side of the fixed base, the left end of the conductive rod is connected with the fixed base, the rainproof cover is nested on the outside of the conductive rod, the left end of the rainproof cover is connected to the fixed base. The base is connected. The invention designs the hinge function of the rainproof cover. Through the hinge, the rainproof cover can be opened 115 degrees backward, so that the internal parts are completely presented in the field of vision of the maintenance personnel, and the contacts can be inspected, cleaned and repaired in all directions. Lubricating oil, and inspection and maintenance.

Description

technical field [0001] The invention relates to an isolating switch contact rainproof cover device which is easy to disassemble and easy to maintain, and belongs to the technical field. Background technique [0002] GW4 type isolating switch is a double-column horizontal rotary isolating switch, (see figure 1 ) The quality of the contact part directly affects the performance of the conductive circuit. The contact part generally has components such as contact fingers and springs. In order to ensure its reliable conductive performance and good working condition, it is necessary to install a rain cover. The function of the rain cover, as the name suggests, is to prevent rain. [0003] At present, the manufacturers of GW4 type isolating switches are different, and the forms are also different. The rainproof cover of the old type isolating switch is generally made of aluminum, with a fully enclosed structure, and is set on the conductive rod, (see Figure 4 ) are fixed with 2 s...
