Distribution network outdoor equipment five-proof smart lock

Abstract

The invention provides a five-proof intelligent lock for outdoor equipment of distribution network, which includes a lock body, a lock rod elastically arranged on the lock body, a lock cylinder rotatably arranged in the lock body, fixedly connected with the lock cylinder in the lock body and The lock bolt movably matched with the lock rod, the pressure plate movably arranged in the lock body to control the opening and closing of the lock, the first and second pressure plate springs respectively supporting the pressure plate from the upper and lower sides in the lock body, and the electronically controlled unlocking assembly; The unlocking components include control board, solenoid, ejector rod, return spring and 2 input electrodes. When in use, the smart lock gets electricity from the matching electronic key through the 2 input electrodes to work and verify the authorization information of the electronic key. After that, the lock can be unlocked; at the same time, the lock can also be unlocked through the matching emergency mechanical key. The invention is easy to carry and use; the invention can improve the efficiency and accuracy of the inspection and unlocking of the power supply department, effectively prevent misoperation, and save the operation and maintenance cost of the five-proof lock for the outdoor equipment of the power supply department.

Description

technical field [0001] The invention relates to a protective lock for distribution network equipment, in particular to an intelligent lock for five defenses for outdoor equipment in a distribution network. Background technique [0002] In the power system, five preventions usually refer to the abbreviation of five anti-error functions for high-voltage electrical equipment to ensure personal safety, and it is one of the important measures for power safety. There are a large number of outdoor equipment in the distribution network, such as ring network cabinets, etc., which need to be protected by locks to prevent losses or accidents caused by unrelated personnel opening the equipment. At present, the locks used in outdoor distribution network equipment are usually mechanical padlocks. Since there are a large number of locking devices such as ring network cabinets and community substations in the same area, the number of padlocks is large. If each lock has a specific correspond...

Problems solved by technology

At present, the locks used in outdoor distribution network equipment are usually mechanical padlocks. Since there are a large number of locking devices such as ring network cabinets and community substations in the same area, the number of padlocks is large. If each lock has a specific corresponding Keys, inspectors need to carry a large number of keys during outdoor inspections. On the one hand, it is inconvenient to carry. On the other hand, when they need to unlock and check the equipment, they need to search for the corresponding key among a large number of keys, which is time-consuming and labor-intensive.

In order to solve this problem, the current practice of the power supply department is to use the same key to unlock the padlocks of the outdoor equipment in the same area, which can effectively solve the problems of inconvenient carrying a large number of keys and time-consuming rummaging for keys. However, it brings The new problem is: on the one hand, there are hidden dangers of misoperation. Taking the common ring network cabinets on the street and roadside as an example, since there are often many ring network cabinets on the same street (road), and the shape and color of the ring network cabinets are basically the same, although There is a number plate on the ring network cabinet, but when the number plate is unclear or falls off, or the inspection personnel are negligent, etc., the A ring network cabinet should be opened for inspection or operation, but the B ring network cabinet is opened, and the power distribution equipment is misoperated. It will bring economic losses and adverse effects, and even cause injury accidents in serious cases; on the other hand, due to the loss or duplication of keys, outdoor equipment in the distribution network may be stolen by illegal personnel (more copper) or artificially destroyed security risks
