[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] A conductive rod for an outdoor high-voltage vacuum circuit breaker. The conductive rod is an accessory installed in an outdoor vacuum circuit breaker and is used for power conduction. Figure 1 As shown, the conductive rod comprises a rod body 1 , the rod body 1 is made of copper, and the outer surface of the rod body 1 is plated with a tin layer.

[0029] The rod body 1 includes a first rod member 11, the diameter of the first rod member 11 is 19-20 mm, one end of the first rod member 11 is fixedly provided with an external thread 12, and the other end is fixedly connected to a second rod member 13, the diameter of the second rod member 13 is 21-23 mm.

[0030] In this embodiment, the diameter of the first rod 11 is 19.85 mm, and the diameter of the second rod 13 is 22 mm.

[0031] The second rod 13 is fixed with an external thread 14 , which is installed and connected to the internal structure of the vacuum circuit breaker. The external thread 14 is arranged at one end of the second rod 13 close to the first rod 11 , and the diameter of the external thread 14 is not less than that of the external thread 12 .

[0032] In this embodiment, the diameter of the second external thread 14 is 22 mm, the diameter of the first external thread 12 is 20 mm, the length of the first external thread 12 is 40 mm, and the length of the second external thread 14 is 24 mm.

[0033] like Figure 1 , Figure 2 As shown, a third rod 16 is fixedly provided at one end of the second rod 13 , and a connecting portion 15 is fixedly connected to the third rod 16 . The connecting portion 15 is fixedly connected to an end of the second rod 13 away from the first rod 11 , and the third rod 16 is fixedly connected to the end of the second rod 13 .

[0034] The third rod 16 is fixedly provided with an external thread three 17 , the diameter of the external thread three 17 is smaller than the external thread one 12 and the external thread two 14 . In this embodiment, the diameter of the external thread three 17 is 16 mm, and the pitch is 2 mm.

[0035] In this embodiment, the rod body 1 is made of an integrally formed round copper rod, and the vacuum circuit breaker conductive rod structure is obtained by milling with a machine tool. The structure is simple, the production is convenient, and the production cost is reduced.

[0036] like Figure 3 , Figure 4 As shown, the ends of the first rod 11 and the second rod 13 are both provided with chamfers 18 .

[0037] Here’s how it works:

[0038] After the vacuum circuit breaker conductive rod is formed by processing the one-piece round copper rod, the conductive rod is installed inside the outdoor vacuum circuit breaker, and is connected to the internal components of the outdoor vacuum circuit breaker through the external thread 12, the external thread 2 14, and the external thread 3 17 respectively. The threaded connection method is convenient to connect and has good assembly firmness. The surface of the overall structure is smooth and bright, and the production and preparation are simple.

[0039] Existing conductive straight rod products usually have notches to facilitate locking during installation, but there are certain risks. Milling a notch with a length of 15 mm and a depth of 1.5 mm on the conductive straight rod increases the difficulty of production and creates more burrs on the surface of the conductive straight rod. When used in outdoor high-voltage vacuum circuit breakers, the notch will cause partial discharge problems in the high-voltage environment, posing certain safety hazards. The burrs in the notch will affect the conductive use of the product.

[0040] The overall structure of the conductive rod in this embodiment is uniform, and the notch is eliminated, so that the conductive rod is easier to install, has a good locking effect with the internal components of the vacuum circuit breaker, has a better product fit, and has better conductive performance.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
