Problems solved by technology
As far as the operating mechanism of the circuit breaker is concerned, there is an independent mechanism represented by ZN28 in the early stage. This mechanism is convenient for organizing production, but it is large in size, complex in structure, and the relative position of the main circuit of the circuit breaker and the transmission system is not accurate; The integrated mechanism represented by ZN63 and VEP has many parts, complicated manufacturing and assembly, and it is inconvenient to debug and maintain the circuit breaker, which is not conducive to industrialized production organization.
These mechanisms generally have a large number of parts and are not compact enough to meet the requirements of integration and standardization of the mechanism, which greatly affects the appearance, miniaturization and overall performance of the circuit breaker.

A spring operation mechanism used for a circuit breaker is characterized in that the mechanism comprises a mechanism support unit, an energy storage unit, an opening and closing unit and a mechanical interlocking unit; the spring operation mechanism is bolted with a framework of the circuit breaker through the mechanism support unit mechanism; the energy storage unit, the opening and closing unit and the mechanical interlocking unit are installed on the mechanism support unit; the energy storage unit is used for energy storage so as to provide power for the spring operation mechanism; the opening and closing unit is used for realizing opening transmission and closing transmission; the mechanical interlocking unit can not carry out closing after the spring operation mechanism carries out closing and is cooperated with a handcart of the circuit breaker so as to realize that closing can not be performed during a shaking process of the handcart.
Description
technical field [0001] The invention belongs to the technical field of high-voltage switches, in particular to a spring operating mechanism for a circuit breaker. Background technique [0002] With the continuous improvement of the technical level of high-voltage vacuum circuit breakers and the continuous improvement of manufacturing processes, high-voltage vacuum circuit breakers are developing towards integration, standardization and miniaturization. As far as the operating mechanism of the circuit breaker is concerned, there is an independent mechanism represented by ZN28 in the early stage. This mechanism is convenient for organizing production, but it is large in size, complex in structure, and the relative position of the main circuit of the circuit breaker and the transmission system is not accurate; The integrated mechanism represented by ZN63 and VEP has many parts, complicated manufacturing and assembly, and it is inconvenient to debug and maintain the circuit brea...
