Intelligent five-prevention unlocking key management device for transformer substation and control method thereof

Abstract

The invention provides an intelligent five-prevention unlocking key management device for a transformer substation and a control method thereof. The method comprises the steps: a five-prevention key management telephone number is set via a touch screen, unlocking is applied on the touch screen, and a management controller can send the unlocking application to the management telephone number through a fixed telephone line; then the management telephone number needs to dial a fixed telephone in the transformer substation in a set time limit after the unlocking application is received, an in-station worker confirms that the call is a unlocking application telephone call of the management telephone number, then successful unlocking information is sent to the management telephone number, the management telephone number receives the information and then the information is fed back to the management controller, an option whether the unlocking is successful is displayed on the touch screen, and the unlocking operation is completed after the field personnel confirm to select successful unlocking, otherwise, the unlocking is failed; and finally, an electromagnetic lock is unlocked, a door isopened, a key is taken, if the door is not closed in a set period of time after the door is opened, the management controller displays alarm information on the touch screen and sends the alarm to themanagement telephone number.

Description

technical field [0001] The invention relates to the technical field of electric power operation management, and more specifically, to a substation intelligent five-proof unlocking key management device and a control method thereof. Background technique [0002] In the daily operation and maintenance of power equipment, if the five-proof system fails or in an emergency, it is necessary to use the five-proof unlock key to release the five-proof lock, and the five-proof unlock key is used without authorization or misuse, which may bring disaster to the safe operation of the power system s consequence. For this reason, some units use mechanical locks to lock the five-proof unlocking key stored in the box. When the on-site personnel need to use the five-proof unlocking key, it is necessary for the five-proof full-time personnel to arrive at the scene in person to unlock the mechanical lock of the box; The five-proof key management machine is adopted, and the five-proof unlocking...
