Safe electric power disconnecting link lock of switch cabinet

Abstract

The invention discloses a safe electric power disconnecting link lock of a switch cabinet. The safe electric power disconnecting link lock of the switch cabinet includes a shell and a lock shaft, the lock shaft is pulled in a lock shaft hole with which the shell is provided, and the safe electric power disconnecting link lock is characterized in that a computer key is inserted in a locking device through a connector assembly, and a magnet is inlaid on the lock shaft, a side wall of the lock shaft hole is provided with a Hall element that senses the magnet; the lock shaft is provided with a pin hole, and an electromagnet corresponding to the pin hole is provided with an elastic mandrel; and the computer key controls popup and pullback of the elastic mandrel through a signal transmitted from the Hall element. By application of the safe electric power disconnecting link lock of the switch cabinet, occurrence of an accident of on-load disconnecting link switching-off is prevented, thereby avoiding a circumstance that accidental outage of a client occurs and causes economic losses.

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 a safe electric knife switch lock for switch cabinets. 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 a saf...
