[0002] A vacuum circuit breaker is a circuit breaker that uses a vacuum state as an arc extinguishing and insulation. It is mainly used in 10-35kV power systems, can be operated frequently, and can continuously break the rated current for more than 10,000 times, and can even break dozens or even hundreds of times continuously under the rated short-circuit breaking current. Vacuum circuit breakers are often used in industrial and mining enterprises, power plants, and substations as protection and control of electrical equipment. Its basic structure includes a vacuum interrupter (vacuum switch tube), an insulating bracket, and an operating mechanism. The advantages of vacuum circuit breakers are small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance, so they are more popular in distribution networks.

[0011] The above one or more technical solutions in a vacuum circuit breaker provided by the embodiment of the utility model have at least one of the following technical effects:

[0012] Through the above technical solution, when the vacuum circuit breaker body is carried, the handles on both sides of the vacuum circuit breaker body are rotated out of the accommodating grooves, and the support plate is rotated out of the connecting grooves, so that the staff can hold the handles to operate when lifting or pulling the vacuum circuit breaker body, thereby solving the problem that the staff has no place to hold their hands when lifting or pulling the vacuum circuit breaker, which makes it inconvenient to move the vacuum circuit breaker over a short distance. It is convenient for the staff to apply force with their hands, thereby facilitating the short-distance movement of the vacuum circuit breaker; at the same time, the support plate provides support for the handle, thereby improving the force strength of the handle.

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are 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.

[0020] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4 As shown, it is a structural schematic diagram of a vacuum circuit breaker in a preferred embodiment of the utility model;

[0023] In this embodiment, a vacuum circuit breaker body 1 is included, and both sides of the vacuum circuit breaker body 1 are provided with accommodating grooves 2, and handles 3 are rotatably provided on the top of the accommodating grooves 2. The two handles 3 include two symmetrically arranged rotating rods 4, and a grab rod 5 is fixedly connected between the two rotating rods 4 by welding. The outer sides of the two rotating rods 4 are provided with connecting grooves 6 and limiting holes 7, and support plates 8 are rotatably provided in the connecting grooves 6. The bottoms of the two inner side walls of the accommodating grooves 2 are provided with movable holes 9, and springs 10 are provided in the movable holes 9. A limiting rod 11 is movably provided at one end of the movable hole 9 away from the spring 10, and the limiting rod 11 can slide along the movable hole 9.

[0024] In this embodiment, the two ends of the spring 10 are respectively abutted against the movable hole 9 and the limiting rod 11, and the spring 10 provides elastic force for the limiting rod 11. When the handle 3 is turned back into the accommodating groove 2, the limiting rod 11 coincides with the central axis of the limiting hole 7, and the limiting rod 11 is pushed into the limiting hole 7 by the spring 10, thereby limiting the handle 3 and preventing the handle from automatically rotating from the accommodating groove 2.

[0025] In this embodiment, the limiting holes 7 are all arranged in an arc-shaped structure, and the end of the limiting rod 11 away from the movable hole 9 is provided with a rounded corner. The end of the limiting rod 11 with the rounded corner is inserted into the limiting hole 7. Through the rounded corner structure and the arc-shaped structure, the limiting rod 11 can be smoothly inserted into the limiting hole 7.

[0026] In this embodiment, the support plates 8 are all arranged in a triangular structure. The support plates 8 can be rotated 180 degrees along the top of the accommodating groove 2. One side of the support plate 8 abuts against the side wall of the vacuum circuit breaker body 1, so that the support plate 8 can be turned out to support the handle 3, which can effectively improve the force strength of the handle 3.

[0027] The vacuum circuit breaker of the utility model has a mounting method, a connection method or a setting method which are all common mechanical methods and can be implemented as long as they can achieve the beneficial effects.
