Intelligent safety warning device for centrally installed switchgear

Abstract

The invention relates to an intelligent safety warning device for a centrally installed switchgear, and belongs to the technical field of intelligent safety warning devices for centrally installed switchgears. The device comprises a supporting frame installed on a switch cabinet door, a circuit board and an LED display screen are installed on the supporting frame, the circuit board is provided with a single-chip microcomputer, a drive circuit and a 220V-5V transformer used for supplying power to the single-chip microcomputer and the drive circuit, and the drive circuit is in communication connection with the LED display screen through an R232 communication port. The single-chip microcomputer is in communication connection with a local area network switch in a switch cabinet through an Ethernet communication port, the local area network switch in the switch cabinet is in communication connection with a local area network switch in a station through an Ethernet communication line, and the local area network switch in the station is in communication connection with a background machine in the station through an Ethernet communication line. The device is high in intelligent degree andgood in warning effect, the maintenance work efficiency is greatly improved, the maintenance power failure time is shortened, resources are saved, and the economic benefits are improved.

Description

technical field [0001] The invention relates to an intelligent safety warning device for a central cabinet, belonging to the technical field of intelligent safety warning devices for a central cabinet. Background technique [0002] At present, the method of labeling and warning of switchgear in the power system is simple and single, which is not economical and practical, and lags behind the pace of smart grid development. The shortcomings are analyzed as follows: [0003] 1. The switch cabinet identification plate generally uses fluorescent paper with red letters on a white background, which is printed and pasted on the switch cabinet surface, but the fluorescent paper identification plate can only be pasted once. When the name and number of the identification plate are wrong or changed, the identification needs to be printed again Not to mention the high price of fluorescent paper, it is a waste of resources only from the perspective of energy renewable utilization.

Problems solved by technology

[0003] 1. The switch cabinet identification plate generally uses fluorescent paper with red letters on a white background, which is printed and pasted on the switch cabinet surface, but the fluorescent paper identification plate can only be pasted once. When the name and number of the identification plate are wrong or changed, the identification needs to be printed again Not to mention the high price of fluorescent paper, it is a waste of resources from the perspective of energy renewable utilization

[0004] 2. When the substation switch is powered off for inspection and maintenance work, the operation and maintenance personnel need to hang "work here" and "no closing, Someone is working!" warning sign, and the "stop, high voltage danger" warning sign is hung on the door of the switch cabinet adjacent to the operation. maintenance time, causing additional pressure to complete the maintenance work on time, indirectly affecting the quality of power supply

[0005] 3. During power outage maintenance, there is no specific hanging position for the power outage warning sign. The usual method is to hang it on the operating handle or the cabinet door (multiple warning signs cannot be hung). This method makes the entire switch cabinet messy, and the warning sign is hung It is not firm and easy to fall. During power outage maintenance, personnel have multiple tasks and heavy tasks. The phenomenon of warning signs falling due to human or external forces often occurs. If the warning signs cannot be hung back in time, it will pose a great threat to the safety of personnel and equipment.

[0006] 4. The existing fluorescent paper signs and power failure warning signs make the surface of the switch cabinet messy, irregular and beautiful, and the degree of intelligence is low, not advanced
