Knife gate for power system with pressurization prompt

Abstract

The invention relates to a knife gate for a power system with pressurization prompt. The knife gate comprises a base. Insulators are fixedly connected with both sides of the top of the base. Accordingto the knife gate for the power system with pressurization prompt, a piston and a light-emitting block are used together; when the knife blade is not closed, the piston moves downward under the action of a lever; the piston compresses the air in a prompt tube, which is equivalent to pressurize more air; the temperature of the pressurized air rises; after the temperature in the prompt tube rises,the light-emitting block absorbs heat and conduct the heat to rare earth phosphor on the surface; the rare earth phosphor emits light after being heated; after the knife blade is closed, the piston rises, and no longer pressurizes the air in the prompt tube; at the moment, the heat of the air is reduced, and the rare earth phosphor on the surface of the light-emitting block no longer emits light;according to whether the light-emitting block emits light, the state of the knife blade is judged; and whether the knife blade is closed is conveniently determined, which prevents equipment from beingdamaged.

Description

technical field [0001] The invention relates to the technical field of knife switches, in particular to a knife switch for a power system with pressurized prompts. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and electricity consumption. There is a switch called a switch in the equipment that consumes electricity, which is used to control the switch of the equipment circuit. , the current knife switch is not easy to see whether it is fully closed when it is closed, it is difficult to judge, and because it is not sure whether it is closed, if it is not fully closed, it is easy to cause a sudden increase in current, causing equipment to burn out and affecting The production of the equipment, and may cause harm to the equipment operators, especially the installation position of the knife switch is relatively rem...

[0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and electricity consumption. There is a switch called a switch in the equipment that consumes electricity, which is used to control the switch of the equipment circuit. , the current knife switch is not easy to see whether it is fully closed when it is closed, it is difficult to judge, and because it is not sure whether it is closed, if it is not fully closed, it is easy to cause a sudden increase in current, causing equipment to burn out and affecting The production of the equipment, and may cause harm to the equipment operators, especially the installation position of the knife switch is relatively remote, the light is relatively dim, and it is difficult to see clearly, so specific criteria are needed to determine whether the switch is closed, so we propose an enhanced The power system with pressure prompt uses a knife switch to solve the above problems
