Problems solved by technology

Purely mechanical locks have fixed programs and inflexible operation, and can only adopt a fixed operation mode. The locks are prone to aging and rust, and the keys are easy to jam. The microcomputer padlock is in the form of a computer simulation operation process, downloading the operation ticket, on-site operation, and the system is easy to operate. Flexible, but the lock is not fixedly installed, it is easy to hang the wrong interval or miss the stroke

Abstract

Disclosed in the invention is an automatic-limiting disconnecting link lock of a switch cabinet. The lock comprises a housing and a lock shaft; and the lock shaft is drawn and pulled in a lock shaft hole formed in the housing. The lock is characterized in that a hoodle is arranged at the lock shaft; and two holes matching the hoodle are formed in the housing. A magnet is embedded into the lock shaft; and hall elements sensing the magnet are arranged at the side wall of the lock shaft hole. Pin holes are formed in the lock shaft; and an elastic mandrel is arranged an electromagnet corresponding to the pin holes. A computer key controls the popping and pulling back of the elastic mandrel based on signals transmitted by the hall elements. With the lock, an accident of loaded disconnecting link pulling can be prevented; and thus accidental power failure of the client can be avoided and the economic loss can be prevented.

Description

technical field [0001] The invention relates to the field of safety operation limiting devices for power distribution cabinets in the electric power industry, in particular to an automatic limit switch cabinet knife lock. Background technique [0002] At present, the locks used in most power switch cabinet latch locks on the market are divided into pure mechanical type and microcomputer padlock type. Purely mechanical locks have fixed programs and inflexible operation, and can only adopt a fixed operation mode. The locks are prone to aging and rust, and the keys are easy to jam. The microcomputer padlock is in the form of a computer simulation operation process, downloading the operation ticket, on-site operation, and the system is easy to operate. It is flexible, but the lock is not fixedly installed, and it is easy to hang the wrong interval or miss the stroke. Contents of the invention [0003] The object of the present invention is to provide an automatic l...
