Power-distribution-network outdoor equipment five-prevention intelligent lock

Abstract

The invention provides a power-distribution-network outdoor equipment five-prevention intelligent lock which comprises a lock body, a lock rod, a lock core, a lock tongue, a pressing plate, first pressing-plate springs, second pressing-plate springs and an electrically-controlled unlocking component. The lock rod is elastically arranged on the lock body, the lock core is rotatably arranged insidethe lock body, the lock tongue is arranged inside the lock body, fixedly connected with the lock core and movably matched with the lock rod, the pressing plate is movably arranged inside the lock bodyand is used for controlling the unlocking and locking, the first pressing-plate springs and the second pressing-plate springs are arranged inside the lock body and support the pressing plate from thetop and the bottom of the pressing plate correspondingly, and the electrically-controlled unlocking component comprises a control plate, a solenoid, a jacking rod, a returning spring and two input electrodes. When the intelligent lock is used, the intelligent lock gains electricity from an electronic key of complementary design through the two input electrodes and works, and after the authorization information of the electronic key is validated to be eligible, the unlocking is performed; and meanwhile the unlocking can be further performed by a matched emergency machinery key. The power-distribution-network outdoor equipment five-prevention intelligent lock is convenient to carry and use, the routing-inspection and unlocking efficiency and accuracy of the power-supplying department are improved by means of the power-distribution-network outdoor equipment five-prevention intelligent lock, misoperations are effectively prevented, and the operational and maintenance cost of the outdoor equipment five-prevention lock can be saved for the power-supplying 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
