Description

technical field [0001] The invention relates to a spring operating mechanism of a vacuum circuit breaker. Background technique [0002] In recent years, on the basis of the continuous improvement of the breaking capacity of the vacuum interrupter, the continuous improvement of the circuit breaker manufacturing process, and the continuous deepening of the theoretical research of the circuit breaker, the medium voltage vacuum circuit breaker has a trend of development towards integration, standardization and miniaturization. At present, the structural form of the medium voltage vacuum circuit breaker operating mechanism is as follows: [0003] 1. The modular distribution of functional units. The components are distributed on the frame of the circuit breaker according to the energy storage module, closing module, opening module and status indication module. The positioning of the circuit breaker body is the positioning of several functional modules. , which makes the assembly ...

Problems solved by technology

[0003] 1. The modular distribution of functional units. The components are distributed on the frame of the circuit breaker according to the energy storage module, closing module, opening module and status indication module. The positioning of the circuit breaker body is the positioning of several functional modules. , which makes the assembly and maintenance of the circuit breaker extremely convenient, but its complex mechanism and large shape bring various inconveniences to the processing and relatively increase the product cost;

[0004] 2. The components are scattered on the circuit breaker frame, and the operating mechanism is characterized by accurate positioning, but there are many components and inconvenient assembly and maintenance, and the relative increase in processing costs is also brought about to ensure the position accuracy of the components;

[0005] 3. The independently installed operating mechanism is a split type. The mechanical characteristics of the circuit breaker must be debugged after installation on the switch cabinet. In addition, the structure is complex and there are many connecting rods, so the relative position accuracy of the operating mechanism and the circuit breaker body is extremely high. Poor, making the matching characteristics of the mechanism output and the transmission system unstable

[0010] Therefore, this type of spring operating mechanism cannot meet the requirements of structural integration, miniaturization, standardization and serialization of production, and further improvement is needed
