Description

Technical Field

[0001] The invention relates to an operating mechanism, in particular to an electric five-protection interlocking operating mechanism. Background Art

[0002] The five-protection interlocking operating mechanism is widely used in power equipment such as high-voltage switchgear and ring network cabinets to ensure that no misoperation occurs during various operations, ensuring the safe operation of the power system and the safety of personnel. The five-protection functions mainly include: 1. Preventing the circuit breaker from being opened or closed by mistake: ensuring that the circuit breaker can only be opened or closed in the correct state to avoid equipment damage or safety accidents caused by misoperation. 2. Preventing the disconnector from opening or closing with load: before operating the disconnector, it is necessary to ensure that the circuit breaker is in the open state to avoid operating with load. 3. Preventing the grounding wire (grounding switch) from being hung (closed) with power on: before the grounding switch is closed, it is necessary to ensure that the equipment is in a power-off state to avoid operating with power on. 4. Preventing the grounding wire (grounding switch) from being closed and energized: ensuring that the circuit breaker cannot be closed and energized when the grounding switch is in the closed state to avoid the equipment being grounded with power on. 5. Preventing the accidental entry into the live interval: when the equipment is energized, prevent personnel from accidentally entering the dangerous area to ensure personnel safety. Modern society has higher and higher requirements for power supply. The development of UHV power grid and the construction of economic, safe, efficient and clean intelligent power grid have become the development trend of power grid. Most of the existing five-protection interlocking operating mechanisms are manually operated without electric operation function. In addition, the existing five-protection interlocking operating mechanisms also have the defects of complex structural design, unreliable interlocking, slow opening and closing speed, unreliable performance and large size. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide an electric five-protection interlocking operating mechanism with simple structure, stable and reliable performance, safety and reliability, small size, reliable interlocking and rapid opening and closing.
