Problems solved by technology

[0004] The invention provides a protective cover, which solves the problem that the existing pressure gauge protective cover in the substation can only realize the rainproof of the partial structure of the pressure gauge, but the exposed structure of the front of the pressure gauge and the secondary junction box causes the pressure gauge to be corroded or damaged Technical problems to ensure that pressure gauges and wiring components are fully protected

Abstract

The invention discloses a protective cover, which belongs to the technical field of instruments and meters, and comprises a cover body, an observation window, a sunshade cover and a locking component. Wherein, the cover body has an accommodating cavity, the front of the cover body is provided with a first opening, the bottom end of the cover body is provided with a second opening, both the first opening and the second opening communicate with the accommodating cavity, the pressure gauge The neck can pass through the second opening, the pressure gauge and the wiring assembly can be accommodated in the accommodating cavity, the observation window covers the first opening, the sunshade is rotatably arranged on the cover body and can cover the surface of the observation window, The locking component is arranged on the body of the cover body and can fasten the neck of the pressure gauge. The protective cover can cover the pressure gauge and the wiring assembly in an all-round way, can effectively prevent sun and rain, ensure the normal operation of the pressure gauge, and prolong the service life of the pressure gauge and the wiring assembly.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a protective cover. Background technique [0002] SF 6 Gas is widely used in substation equipment due to its good insulation and arc extinguishing properties. GIS (GASinsulated SWITCHGEAR) is the English abbreviation of gas-insulated fully enclosed combined electrical appliances. In the outer shell, the interior is filled with a certain pressure of SF 6 Insulating gas, so it is also called SF 6 Fully enclosed combined electrical appliances. To monitor SF 6 Gas pressure, judge SF 6 Whether there is a gas leak and an alarm or blocking signal occurs, each gas chamber on the GIS equipment is equipped with SF 6 pressure gauge. Therefore, for outdoor GIS electrical equipment, do a good job of SF 6 It is particularly important to ensure the normal operation of the pressure gauge for the rainproof and sunscreen measures of the pressure gauge. [0003] (1) At pres...
