A pressurized prompting power system knife switch

Abstract

The utility model relates to a knife switch for a pressurized prompt power system, which includes a base, and insulators are fixedly connected to both sides of the top of the base. The pressurized prompt power system uses a knife switch, which is used in conjunction with the piston and the light-emitting block. When the switch knife is not closed, the piston moves downward under the action of the lever, and the piston compresses the air in the prompt tube, which is equivalent to more The air is pressurized, and the temperature of the air will rise after pressurization, indicating that after the temperature in the tube rises, the light-emitting block will absorb the heat and transfer the heat to the rare earth phosphor on the surface, and the rare earth phosphor will emit light after being heated , when the switch is closed, the piston will rise, and the air in the prompt tube will not be pressurized. At this time, the heat of the air will decrease. At this time, the rare earth phosphor on the surface of the light-emitting block is no longer emitting light, so whether the light-emitting block is shining To judge the state of the switch knife, so as to facilitate the judgment of whether the switch knife is closed, and avoid damage to the equipment.

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
