[0028] The mounting assembly 4 includes a half ring 41 , a bolt 42 and a nut 43 . Two half rings 41 are symmetrically mounted on both sides of the left cover 11 and the right cover 12 . The bottom surface of the half ring 41 fits with the top surface of the left cover 11 and the right cover 12 .
[0029] First bolt holes 421 are provided at the bottom of both sides of the semi-ring strip 41, and second bolt holes 422 are provided at positions corresponding to the first bolt holes 421 on the left cover body 11 and the right cover body 12. The bolts 42 pass through the first bolt holes 421 and the second bolt holes 422, and nuts 43 are installed at the tail ends of the bolts 42.
[0030] The diameter of the through opening 2 is larger than the diameter of the body of the porcelain column 3 and smaller than the diameter of the porcelain skirt of the porcelain column 3 .
[0031] Specifically, during installation, align the semicircular hole 13 with the interval of the porcelain skirt of the porcelain column 3 and bring the top ends of the left cover body 11 and the right cover body 12 together. At this time, the porcelain column 3 is located in the through-opening 2. Then, place the two semi-ring strips 41 on the top of the left cover body 11 and the right cover body 12, and insert the bolt 42 into the first bolt hole 421 and the second bolt hole 422 in turn. Finally, screw in the nut 43, and repeat the above steps to complete the remaining installation.
[0032] Specifically, the left cover 11 and the right cover 12 are provided to shield and protect the isolating switch, which can effectively prevent birds from building nests between the porcelain columns 3 of the isolating switch, reduce or eliminate line power outages caused by bird damage, improve power supply reliability, and increase economic benefits.
[0033] Embodiment 2:
[0034] See also Figure 6-7 The difference between this embodiment and the first embodiment lies in the mounting assembly 4. The rest of the parts are the same as the first embodiment. The mounting assembly 4 includes a mounting plate 44, a through column 45 and a through button 46. The mounting plate 44 includes a first mounting plate 441 and a second mounting plate 442. Two of the first mounting plates 441 and the second mounting plates 442 are provided respectively. The first mounting plates 441 and the second mounting plates 442 are respectively fixed at the intersection of the left cover body 11 and the right cover body 12.
[0035] Two through columns 45 are fixed on one side of the first mounting plate 441 facing the second mounting plate 442, and through buttons 46 are fixed on the ends of the through columns 45, and the cross-section of the through buttons 46 is trapezoidal; a through hole 47 is opened at a position of the second mounting plate 442 corresponding to the through button 46, and the through button 46 penetrates into the through hole 47 and abuts against the side of the second mounting plate 442; the diameter of the through hole 47 is smaller than the diameter of the larger end of the through button 46, and the length of the through column 45 is equal to the thickness of the second mounting plate 442.
[0036] Specifically, the through button 46 is made of an elastic material, which has a certain elasticity and toughness.
[0037] Specifically, during installation, align the semicircular hole 13 with the interval of the porcelain skirt of the porcelain column 3 and bring the top ends of the left cover body 11 and the right cover body 12 together. At this time, the first mounting plate 441 and the second mounting plate 442 are close to each other, and the second mounting plate 442 is against the through button 46. Align the through button 46 with the through hole 47, and pinch the first mounting plate 441 and the second mounting plate 442 by hand. The through button 46 is deformed during the pressure application process and passes through the through hole 47, thereby realizing the combination of the first mounting plate 441 and the second mounting plate 442. This installation method does not require the use of any tools and is convenient and quick to install.
[0038] Working principle: align the semicircular hole 13 with the interval of the porcelain skirt of the porcelain column 3 and bring the top ends of the left cover body 11 and the right cover body 12 together, at this time the porcelain column 3 is located in the through opening 2, then place the two semi-ring strips 41 on the top of the left cover body 11 and the right cover body 12, insert the bolts 42 into the first bolt hole 421 and the second bolt hole 422 in turn, and finally screw in the nut 43 to complete the installation; the left cover body 11 and the right cover body 12 shield and protect the disconnector knife switch, effectively preventing birds from nesting between the porcelain columns 3 of the disconnector.
