Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-4 are referred to, the present invention provides a kind of technical scheme：A kind of high-voltage electrical apparatus controls knife switch, including shell 1
With handle 6, the left hand external of shell 1 is provided with baffle plate 2, and the outside of shell 1 is convex structure, and the inside of baffle plate 2 is concave structure, and outside
The external male structure of shell 1 matches with the inside spill construction profile size of baffle plate 2, can be to shell 1 when switch blade mechanism 8 is closed
Outside opening is stopped, further reduces the path that dust enters device, the lower end of baffle plate 2 is provided with thrust spring 3, and pushes away
Power spring 3 is located at the left side lower end of shell 1, and the largest deformation amount of thrust spring 3 is equal to the half of the length of baffle plate 2, enables to baffle plate 2
Possess the trend moved upwards, when switch blade mechanism 8 is closed, because of the effect of thrust baffle plate 2 can be closed, on baffle plate 2
End is provided with runner 5, can reduce the resistance between device, reduces under the frictional force between baffle plate 2 and switch blade mechanism 8, handle 6
End is provided with sealing ring 7, and sealing ring 7 is located inside the upper end of shell 1, and sealing ring 7 is circlewise uniformly arranged on the lower end table of handle 6
Handle 6 and shell 1, effectively can be attached by face, reduce the gap between handle 6 and shell 1, reduce dust and enter dress
The probability of inside is put, reduces influence of the dust to device electric elements inside, the lower end of handle 6 is provided with switch blade mechanism 8, and plug-in strip
The lower end of mechanism 8 is connected by rotating shaft 4 with the first terminals 10, and switch blade mechanism 8 includes the first plug-in strip section 801, tension spring 802
