Technical Field
[0001] The utility model relates to the technical field of isolating switch accessories, in particular to an isolating switch protective cover. Background Art
[0002] Isolating switches are important switching devices in the electrical systems of power plants and substations. Their functions are to ensure the safety of high-voltage electrical appliances and devices during maintenance work and to isolate voltage. Outdoor isolating switches are exposed to the outside for a long time, and insulators are easily eroded by rain and contaminated by bird excrement, resulting in dirty flashover.
[0003] In order to improve the service life and voltage stability of the isolating switch, a protective cover device is usually installed on the outside of the isolating switch to protect it. However, this protective cover has poor protective effect and may cause rainwater and debris to penetrate. The heat generated by the isolating switch is not easy to dissipate, causing safety hazards.

[0006] Preferably, the middle positions at the front and rear ends of the top of the first filter are fixedly connected to limiting blocks, and the middle positions at the tops of the two limiting blocks are fixedly connected to the second handles.
[0007] Preferably, mounting plates are fixedly connected to the middle positions on the right sides of both front and rear ends of the box body.
[0008] Preferably, a first handle is fixedly connected to the top middle of the right side of the box cover.
[0009] Preferably, the middle positions of the front and rear ends of the box cover are fixedly connected with snap locks, and the middle positions of the front and rear ends of the box body are fixedly connected with snap locks.
[0010] Preferably, a fixing block is fixedly connected to the middle position of the front and rear ends of the bottom of the second filter screen.
[0011] The beneficial effects of the utility model are as follows:
[0012] In the utility model, when the box cover is engaged with the box body, the airtightness of the protective cover is improved by the engagement of the rubber ring and the annular groove. In rainy weather, residual rainwater on the box body and the box cover flows into the water collection trough, and the rainwater can be discharged through the water flow groove to prevent the rainwater from seeping into the isolating switch. When the isolating switch overheats and causes the temperature in the box body to be too high, the cooling fan is turned on to discharge the heat in the box body from the heat dissipation port. The protective effect of the protective cover is effectively improved by increasing the airtight effect of the protective cover and discharging rainwater in time. At the same time, the safety hazard of using the protective cover is reduced by improving the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS
