Abstract

The invention discloses an insulator anti-condensation device of a high-voltage dust removal system. The anti-condensation device comprises an outer anti-condensation mechanism, an inner anti-condensation mechanism and an insulator; by arranging the outer anti-condensation mechanism and the inner anti-condensation mechanism, the purpose of rapid heating is achieved; the inner wall of a shell plateis fixedly connected with a heat insulation layer; a first heating element is arranged on the inner side of the heat insulation layer; the contact surface of the first heating element and the outer wall of the insulator is made of ceramic, thereby improving thermal conduction and heating effects; the arrangement of the heat insulation layer achieves a good heat preservation and insulation effect;the first heating element is positioned on the outer side of the inner anti-condensation mechanism; the insulator is mounted in the insulator mounting cavity; the expansion rod expands the expansionpipe through the U-shaped groove, so the purpose of fixing the device is achieved, and the whole inner anti-condensation mechanism is more stable; the first heating element and the second heating element are both located on the lower portion of the periphery of the insulator, and only the insulator is heated, so energy consumption and cost are reduced; and the heat conduction silica gel plays a certain role in heat conduction and heat preservation while protecting the insulator.

[0002] In electric equipment, the electrostatic high-voltage dust collector is an important piece of electric power equipment, and is widely used in electric power maintenance. In the interior of the electrostatic high-voltage dust collector, the insulator is a necessary component to realize the electrical isolation of 40KV high voltage and the earth. However, because the interior of the electrostatic high-voltage dust removal device often contains a large amount of water vapor, if the temperature of the insulator is low, water vapor will easily form condensation on the surface of the insulator. Water, as a conductor, transmits part of the high-voltage electricity to the earth, causing severe The phenomenon of creepage and leakage caused the dust removal system to fail to work normally. However, the current anti-condensation methods for insulators are divided into internal devices or external devices. The heating effect is poor, the heating speed is slow, effective heat preservation cannot be achieved, and the power consumption is large. Waste resources and increase costs
