Switchboard surface knife switch anti-static dust adsorption device

Abstract

The invention discloses a switchboard surface knife switch anti-static dust adsorption device which comprises a switchboard body. A knife switch is rotatably connected to the surface of the switchboard body, a deflection rod is rotatably connected to the side face of the knife switch, and a pull rod is rotatably connected to the bottom of the deflection rod, and an air extracting plate is fixedlyconnected to the side, away from the deflection rod, of the pull rod. An air box is slidably connected to the side face of the air extracting plate, a wind shielding wheel is engaged with the surfaceof the ratchet wheel, and an air extracting pipe is fixedly connected to the top of the air box. An air baffle is arranged in the air extracting pipe, an ejector rod is arranged at the side, close tothe knife switch, of the air baffle, a supporting rod is slidably connected to the side, away from the air baffle, of the ejector rod, and the top of the supporting rod is fixedly connected with a gate groove wheel. According to the switchboard surface knife switch anti-static dust adsorption device, through the cooperative use of the deflection rod and the air box, the effect of preventing dust in air from being adsorbed by static electricity on the surface of the switchblade when the knife switch is closed is achieved.

Description

technical field [0001] The invention relates to the technical field of switchboards, in particular to an anti-static dust adsorption device for switch blades on the surface of a switchboard. Background technique [0002] The switchboard, also known as the power distribution cabinet, is a device for concentrating, switching, and distributing electric energy. The switchboard is generally composed of a cabinet, a shutdown, a protection device, a monitoring device, an electric energy meter, and other secondary components. According to the current, it can be divided into AC and DC switchboards, and according to the voltage, it can be divided into lighting switchboards and power switchboards, or high-voltage switchboards and low-voltage switchboards. [0003] There is a switch knife on the surface of the switchboard to close. When the swing switch knife is closed to make it energized, the switch knife is suddenly energized to generate static electricity on the surface. Since the s...
