The invention provides a switch cabinet circuit breaker closing knob locking device and a switch cabinet group. The locking device comprises a base plate, a baffle plate, a locking component, and a follower. The base plate covers an operation panel, and is provided with openings in positions corresponding to the closing knob and an energy storage mechanism. The baffle plate is movably arranged on the base plate between a first setting position and a second setting position through a plurality of connectors. The locking component is arranged on the base plate and is used to lock the baffle plate when the baffle plate is in the second setting position. The follower is fixed to the energy storage mechanism. After the baffle plate is in the first setting position and the closing knob is rotated, the follower is driven by the energy storage mechanism to rotate, then stops rotation and blocks the baffle plate from moving to the second setting position. By fixing the follower to the energy storage mechanism and rotating the follower to the position for blocking the baffle plate, the locking component is enabled to lock the closing knob indirectly, and thus, the safety is increased.
Description
technical field [0001] The invention relates to a locking device of a circuit breaker closing knob of a switch cabinet and a switch cabinet group. Background technique [0002] At present, in the field of power distribution, a dual power supply or even multiple power supply scheme is usually adopted to ensure that the power supply to the load can be switched in time when a fault occurs, so as to ensure the safety of electrical equipment. However, in order to avoid the main power supply and the backup power supply supplying power at the same time when the dual power supply enters the line, it will cause damage to the electrical equipment and potential safety hazards. Generally, interlocking is carried out at the incoming line end of dual power supply or multi-power supply to ensure that only one power supply supplies power at the same time. [0003] At present, the commonly used switchgear is equipped with a handcart type vacuum circuit breaker, and the locking function of t...
