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

Embodiment Construction

[0013] As shown in the figure, a knife lock for a power switch cabinet includes a housing 6 and a lock shaft 10. The lock shaft 10 is pulled in the lock shaft hole provided on the housing 6. There are preset position points on the lock shaft 10. 7. The side wall of the lock shaft hole is provided with a displacement sensor 13 that senses the displacement change of the preset position point 7; the lock shaft 10 is provided with a pin hole, and an elastic mandrel is set at a position corresponding to the pin hole; The incoming signal is judged to control the pop-up and pull-back of the elastic mandrel. The back of the lock shaft 10 is provided with a groove, and the positioning pin 17 provided on the housing 6 cooperates with the groove. The displacement sensor judges the preset position The displacement of point 7 is used to detect the pulling position of the lock shaft 10. The lock shaft 10 is provided with two pin holes, and the electromagnet 11 is also provided with a sen...

Abstract

Disclosed in the invention is a disconnecting link lock of a power switch cabinet. The disconnecting link lock comprises a housing and a lock shaft; and the lock shaft is pulled out from a lock shaft hole formed in the housing. The disconnecting link lock is characterized in that a displacement sensor for sensing the lock shaft displacement is arranged at the side wall of the lock shaft hole. A pin hole is formed in the lock shaft; and an elastic mandrel is arranged at an electromagnet corresponding to the pin hole. A computer key determines and controls the popping and pulling back of the elastic mandrel based on transmitted signals. With the disconnecting link lock, an accident of loaded disconnecting link operation can be prevented; and accidental power failure of a client can be avoided and thus economic losses 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 a knife lock for a power switch cabinet. 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 knife switch lock...
