[0028] The inner sides of the two threaded connecting plates 7 are fixedly installed with positioning clamps 8 for fixing the U-shaped seat 2, and the upper end surfaces of the two threaded connecting plates 7 are connected with cross plates 10. The interior of the U-shaped seat 2 is connected with two limiting round rods 9 for guiding the threaded connecting plates 7. Through the setting of the limiting round rods 9, the two limiting round rods 9 can limit the movement trajectory of the two threaded connecting plates 7, so that the two threaded connecting plates 7 can move back and forth smoothly, so as to clamp and fix the indoor intelligent vacuum circuit breaker, thereby improving the installation efficiency. The inner sides of the two cross plates 10 are connected with positioning columns 11 for fixing the vacuum circuit breaker body 3 in an array.

The inner side surfaces of the positioning posts 11 are slidably engaged with the two ends of the vacuum circuit breaker body 3 through the circular grooves 222 .

[0035] The working principle of an indoor intelligent vacuum circuit breaker provided by the utility model is as follows:

[0036] By placing the U-shaped seat 2 onto the indoor installation base plate 1, and then placing the entire vacuum circuit breaker body 3 onto the top of the U-shaped seat 2, and then turning the connecting hand wheel 6, the connecting hand wheel 6 will drive the bidirectional threaded shaft 5 to rotate, and at this time, the two threaded connecting plates 7 on the bidirectional threaded shaft 5 can move toward each other, so that the two threaded connecting plates 7 can drive the two positioning clamps 8 to reduce the spacing and clamp them into the card groove 111 of the indoor installation base plate 1, so as to clamp and fix the vacuum circuit breaker body 3 at the U-shaped seat 2, and then the two threaded connecting plates 7 will also drive the two horizontal plates 10 The positioning columns 11 are moved toward each other and snapped into the circular groove 222 of the vacuum circuit breaker body 3, so that the indoor intelligent vacuum circuit breaker can be stably positioned by snapping, which is convenient and quick to operate. At the same time, the four limit rotary plates 12 are rotated into the grooves 14 at the indoor installation base plate 1, and then the four plug posts 13 are inserted into the indoor installation base plate 1 and the limit rotary plates 12, so that the limit rotary plates 12 and the plug posts 13 can limit and fix the vacuum circuit breaker again, so that the indoor intelligent vacuum circuit breaker can be quickly fixed, and the working efficiency of the indoor intelligent vacuum circuit breaker during loading and unloading is improved;

[0037] By allowing the two embedded plates 15 to be snapped into the inside of the two fixing seats 23, the two vertical plates 18 equipped with the damper 17 and the connecting spring 20 can be driven to be fixed above the two embedded plates 15. At this time, the arc-shaped protective frame 19 is inserted above the two vertical plates 18, and then the two fastening bolts 22 are rotated so that the fastening bolts 22 can squeeze and fix the entire arc-shaped protective frame 19, ensuring that the arc-shaped protective frame 19 can be installed above the vacuum circuit breaker body 3. Then, the characteristics of the damper 17 that can absorb impact force and the elastic deformation of the connecting spring 20 can be used to increase the buffering capacity of the arc-shaped protective frame 19. The rubber pad 21 on the arc-shaped protective frame 19 can further protect and buffer, thereby strengthening the protection of the indoor intelligent vacuum circuit breaker and preventing the indoor intelligent vacuum circuit breaker from being easily damaged by external forces.
