Background

In the electric power system transformer substation, besides outdoor primary equipment, the electric power system transformer substation also comprises a master control room, a relay protection room, a switch room, a communication machine room and other rooms. The indoor equipment, especially the switch room, is densely covered with the point-carrying equipment and the secondary line, and if a small animal enters the electrified interval by mistake or destroys the secondary line, the result is very serious. Conventionally, in order to protect the substation indoor equipment from being damaged by small animals, a combination of a door mounting baffle and a mouse trap is generally adopted to ensure the safe operation of the substation indoor equipment. However, in the process of maintenance and inspection, the fixedly installed baffle blocks the normal entrance and exit of people, and even certain safety risks exist. The mousetrap placed indoors can only passively trap mice, and the effect is very little.

The patent with the publication number of 106719594A discloses a rat guard for a power transmission and transformation station, which comprises an electric push rod, a control box, an infrared inductor, an upper baffle plate, a lower baffle plate, a left slide rod, a roller shutter door, a right slide rod and a slide block, wherein the infrared inductor is connected to the electric control box; the left end of the upper baffle is fixedly connected to a second sliding block, the second sliding block is connected to a left sliding rod in a sliding mode, and the left sliding rod is fixedly installed on the left side of the substation door; the upper baffle is fixedly connected to the upper end of the rolling door, the lower end of the rolling door is fixedly connected to the lower baffle, and the lower baffle is fixedly installed on the floor of the transformer substation.
