Technical Field

The invention belongs to the technical field of circuit breakers, and particularly relates to a padlock structure of a circuit breaker handle, which improves the reliability of the padlock of the circuit breaker handle.

Background

The circuit breaker is generally installed in the switch cabinet and is connected with an external operating handle through a connecting square shaft to operate the switching on and off of the circuit breaker. The connecting square shaft is fixed on the breaker body and is in inserted flexible connection with the handle outside the cabinet. If the connecting square shaft and the cabinet outer handle are locked and cannot be pulled out, the cabinet door cannot be opened.

When the breaker is in a breaking state, the electric line can be overhauled and the like. In order to prevent the circuit breaker from being switched on at this stage, which causes various accidents, the circuit breaker needs to be locked. This function is often operated by locking the handle. The handle is often used for locking the padlock piece in the handle, so that the phenomenon that the breaker is accidentally closed by people is avoided.

When the breaker is in a switching-on position, the connecting square shaft is locked, and the cabinet door cannot be opened; if the cabinet door is to be opened, the sliding plate is pressed, and the sliding plate is moved to the right to unlock the connecting square shaft, so that the cabinet door can be opened temporarily.

If the padlock of using is not normal, cause the padlock spare perk angle probably not in place, cause the retainer can't insert the target in place, make the unable reliable locking of square shaft of connecting, even the padlock also can appear opening the cabinet door direct operation switch risk of closing the branch. The padlock device with the handle outside the existing cabinet is mostly of a hand-pulling rotation tilting structure, and after hand-pulling force disappears, the padlock part automatically falls back under the action of restoring spring force. The padlock part has no positioning function and is completely limited by the padlock. The locking function of the handle can only be met, and the requirement on the locking function of the cabinet door is low.

Chinese patent No. 200420054892.5 discloses a cubical switchboard operating handle, including the handle body, installation chassis and set up in the handle body and act on the handle location rotation-proof mechanism on installation chassis, wherein installation chassis rotates with the handle body to be connected its characterized in that: the handle positioning anti-rotation mechanism comprises a locking block with a return spring and a safety locking plate, and the locking block is in positioning fit with the second station of the safety locking plate. The operating handle can be operated by a single person with a single hand, and the locking function of the handle is met. But the locking function of the cabinet door is not reliable. If the padlock of using is not normal, cause the padlock spare perk angle probably not in place, cause the retainer can't target in place, make the unable reliable locking of square shaft of connecting, even the padlock also can appear opening the risk that the cabinet door direct operation switch closes the separating brake.

Chinese patent CN 209104018U discloses a manual operating mechanism handle of a circuit breaker, which is characterized by comprising an operating handle, a padlock device and a locking shaft, wherein the middle part of the padlock device is arranged on the operating handle in a pivoting way, the front end of the padlock device is connected with the locking shaft, the padlock device is connected with the operating handle through a first driving piece, the rear end of the padlock device is in limit fit with the locking mechanism, the rear end of the padlock device is provided with a padlock hole, and the padlock hole is shielded by the operating handle; when the circuit breaker is in a brake separating state, the locking mechanism is unlocked, the first driving piece enables the front end of the padlock device to sink, the locking shaft is driven to lock the operating handle, and meanwhile, the rear end of the padlock device is tilted, so that the padlock hole is separated from the operating handle. But this operating device handle only can satisfy the reliability of locking the function to the handle, and is locking the function unreliable to the cabinet door, has the safety risk to the maintainer, and has increased part quantity, leads to the cost increase.
