Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-4, a bus insulation protection device for a medium voltage power grid comprises a device base 1 and a device top cover 2, the device top cover 2 is arranged on the top surface of the device base 1, fixing clips 3 are arranged on the inner walls of the device base 1 and the device top cover 2, conductor metal bars 5 are arranged on the inner sides of the fixing clips 3, heat dissipation grooves 4 are arranged on the side walls of the device base 1 and the device top cover 2, each fixing clip 3 comprises a C-shaped clip 31, the C-shaped clip 31 can be made of ceramic materials and is integrally formed, a clip 32 is arranged on one side of the C-shaped clip 31, a clip groove 33 is arranged on the other side of the C-shaped clip 31, fixing grooves 34 are arranged on the two sides of the C-shaped clip 31 close to the bottom of the clip 32 or the clip groove 33, a sliding rod 8 is arranged on the side wall of the device base 1 and the device top cover 2 close to the fixing, the side walls of the device base 1 and the device top cover 2 close to the sliding rod 8 are provided with sliding grooves 10, and one side of the fixture block 7 close to the C-shaped fixture block 31 is provided with a projection corresponding to the clamping groove 33.
