Substation anti-small animal intrusion device

Abstract

The invention discloses a substation anti-small animal intrusion device, which relates to the technical field of electrical safety control of a substation. At least two conductors respectively connected to the positive pole and the negative pole of the direct current is arranged along the inner side of the wall of the power distribution room of the substation. The lower part of the conductor is isolated by an insulating material to ensure that the earth is not in contact with the conductor; small animals will get electric shock or death in the distribution room if they pass through the wall and enter the distribution room. A coil of a current type signal relay is connected in series to a conductor connected to the positive or negative pole of the direct current. A trip switch SQ is installed on the door of the power distribution room of the substation, and the trip switch SQ can control the on and off of the connection between the conductor and the direct current. The whole device costs low and can effectively prevent small animals from invading the substation, which is safe for operators. After the small animal invades the power distribution room of the substation, the current signals relay alarm will be triggered, which can promptly sent an notification to the substation watchman.

Description

technical field [0001] The invention relates to the technical field of substation electrical safety management and control, in particular to a small animal intrusion prevention device for a substation. Background technique [0002] The safe operation of substations is a necessary condition to ensure the stability of industrial and agricultural production and the stability of urban and rural people's lives, and preventing the intrusion of small animals is one of the important measures to ensure safe operation. How to prevent small animals (mice, weasels, cats, snakes, etc.) from entering the substation and causing short-circuit blackout accidents is a problem that cannot be ignored and must be paid great attention to. [0003] The frequent season for small animals to enter the cable trenches, power distribution rooms and switch cabinets of substations is late autumn and early winter. During this period, as the weather gradually turns cold and outdoor food decreases, small ani...

AI Technical Summary

Problems solved by technology

After entering the power distribution room and switch cabinet, they will scurry around in high-voltage busbars, switches, knife switches, cable terminal blocks, transformer pile heads, etc., causing arc short-circuits to burn down equipment and even cause large-scale power outages

[0004] Once a power outage occurs, it will bring great inconvenience to industrial and agricultural production and people's lives, and will also affect the assessment of the safe operation of the substation by the superior competent department
