Problems solved by technology
[0002] There needs to be a reliable interlock between the circuit breaker mechanism and the three-position mechanism in the high-voltage switch. Generally, the reliability and stability of the interlock operation between the circuit breaker mechanism and the three-position mechanism is not very good. When the circuit breaker is closed, the three-position mechanism is easy Misoperation occurred

The invention provides an interlocking device of a circuit breaker mechanism and a three-station mechanism. The interlocking device comprises a connecting lever, a support plate fixed to the three-station mechanism, a first guide plate installed on the support plate, a second guide plate installed on the first guide plate, a connection rod installed on the first guide plate, a third guide plate connected to the connection rod and a locking rod installed on the first guide plate, the second guide plate and the third guide plate. One end of the connecting lever is installed on a spline shaft of a circuit breaker. The other end of the connecting lever is connected to one end of a first connection plate. The other end of the first connection plate is connected to one end of a second connection plate. In the invention, when the circuit breaker is closed, interlocking of the three-station mechanism can be ensured to be reliable and stable; and maloperation is prevented and a switch cabinet is ensured to work normally.
Description
technical field [0001] The invention relates to the field of medium and high voltage switch cabinets, in particular to an interlocking device of a circuit breaker mechanism and a three-station mechanism. Background technique [0002] There needs to be a reliable interlock between the circuit breaker mechanism and the three-position mechanism in the high-voltage switch. Generally, the reliability and stability of the interlock operation between the circuit breaker mechanism and the three-position mechanism is not very good. When the circuit breaker is closed, the three-position mechanism is easy A misoperation has occurred. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an interlocking device between the circuit breaker mechanism and the three-position mechanism, which can prevent the misoperation of the three-position mechanism when the circuit breaker is closed. [0004] To achieve the above object, the techni...
