Description
Technical Field
The invention belongs to the technical field of operation and maintenance of transformer substations, and particularly relates to dust prevention of equipment.
Background
A substation is a location where voltage is changed. In order to transmit the electric energy generated by the power plant to a remote place, the voltage must be increased to become high voltage, and then the voltage is reduced as required near the user, and the voltage increasing and reducing work is completed by a transformer substation.
Many devices operated in the transformer substation are arranged in the box body, so that a box body structure is formed, such as a switch cabinet, an alternating current and direct current screen, a control cubicle and the like. In the operation process of the equipment, the ambient temperature can be increased due to the heating equipment such as a transformer or a capacitor, hot air is not easy to diffuse in a narrow box space, and the loss rate and the failure rate of the equipment can be increased seriously when the equipment is operated in a high-temperature environment for a long time. Therefore, the cabinet body is required to be provided with a vent to radiate hot air, so that the operation of the equipment is ensured. However, there are many induced electricity in the operating environment of a substation that can cause dust particle-containing gases to accumulate on the electrical components of the equipment. This in turn can hinder the heat dissipation of the electrical components due to the accumulation of dust. Many dust collecting devices have been developed, such as:

These prior arts are to put a device having a dust collecting function at the opening to block the entrance of dust. Most of the dust collecting devices are filter screens, metal rods arranged densely and dust collecting plates, and the structures have the characteristics of large area and small pores and can block dust. However, these structures can also block the ventilation holes on the box body, so that the air circulation is not smooth, the discharge of hot air is blocked, and the problems of heat dissipation and dust prevention of the box body cannot be simultaneously considered.

The electrostatic rod 1 is rotatably connected with the screw 3, so that the electrostatic rod 1 can rotate by taking a main shaft of the electrostatic rod as a rotating shaft, and when any one of the electrostatic rods 1 moves to a position opposite to the roller hole 12, the outer circumferential surface of the electrostatic rod 1 can be in contact with the adhesion roller 8 extending into the roller hole 12. The adhesion roller 8 is fixed to the outer surface of the ventilation panel 11 by a roller frame 9.
In the present embodiment, the electrostatic rod 1 can contact the adhesion roller 8 when moving to the position of the adhesion roller 8, and the dust on the electrostatic rod 1 is adhered by the viscosity. The staff need not to shut down, only need take off adhesion roller 8 can reach the purpose of clearance. Further, the circumferential surface of the adhesive roller 8 is a dust-binding paper which is layered and wrapped. The operator directly tears off the dust-binding paper to expose new dust-binding paper, the adhesive roller 8 does not need to be disassembled, and the workload of the operator is reduced.
The working principle of the electrostatic dust collector is that a high-voltage electric field is utilized to ionize smoke, and dust charges in airflow are separated from the airflow under the action of the electric field. The cathode is made of metal wires with different cross-section shapes, and is called a discharge electrode.
