Pneumatic disconnection and dust removal device and method for distribution box

Abstract

The invention relates to a device and method for pneumatic disconnection and dust removal for a distribution box. Its technical solution is: the outside of the electric key is connected to the electric key control cylinder through a connecting rod, the electric key control cylinder is connected to the control reversing air valve through the closed air pipeline, and the control reversing air valve is connected to the air cylinder through the remote air transmission pipeline. Compressor air storage tank, and a cut-off valve is provided on the remote gas transmission pipeline, the air compressor air storage tank is connected to the air compressor, and the air compressor is used to press the control reversing air valve to realize the switch of the electric key; the distribution The lower side of the main body of the electric box is provided with a dust removal pipe, and a solenoid valve is arranged on the dust removal pipe, and is connected to the gas storage tank of the air compressor. The beneficial effect is: the present invention uses gas as the power, which can avoid or reduce the interference of electromagnetic field on human physiology, and through the induction circuit composed of dust attracting capacitor, gas circuit opening coil and rectifier, automatic induction and dust removal become possible, avoiding The physical damage caused by manual dust removal is avoided.

[0002] Electricity is the driving force of modern industry. In the process of electric power transmission, changing high voltage to low voltage is a common situation encountered by electric power departments. At present, the operation of changing high voltage to low voltage on the distribution box is mostly manual operation. The process is, a The operation should be monitored by more than two people. This is an important safety measure written into the operating procedures, otherwise it is not allowed to operate. In this way, the operation is not only troublesome, but also the operator will be affected by electromagnetic interference and affect people's physical and mental health. , therefore, we invented a device for pneumatically disconnecting electricity

[0003] In addition, the wiring box also involves dust-proof issues: First, it is to prevent some exposed components in the cabinet from being covered by dust. If it is covered by dust and then absorbs moisture in the air, it will corrode some exposed components. A long time may lead to insulation reduction, short circuit, grounding and other faults, and may even lead to the risk of electric shock; 2. Excessive dust coverage will lead to excessive electrostatic current in the case of humid air, which will also cause it to be damaged during operation. The danger of electric shock, and excessive dust coverage will cause corrosion to the components of the box, and will greatly shorten the service life of the components

This patented technology uses ultrasonic vibration components to cooperate with air to remove dust. This operation requires power-off operation of the distribution box, and dust removal is not carried out when the power is charged, which affects the power supply.
