Based on rain-proof heat dissipation variable frequency control cabinet of oil field digitization

Technical Field

The utility model relates to a variable frequency control cabinet is particularly a based on rain-proof heat dissipation variable frequency control cabinet of oil field digitization.

Background

In recent years, along with the large-scale construction of oil field digitization technology of victory oil field branch companies of China petrochemical industry, a novel standard variable frequency control cabinet is taken as standard equipment for data acquisition, and is purchased and used by more and more units due to convenient parameter adjustment, simple field data acquisition and reasonable functional area division. However, in use, the shortcomings of the control cabinet are increasingly appearing, wherein the biggest problem is that the heat dissipation design is not reasonable. There are mainly the following problems: first, switch board brake resistance is integrated inside the top cap, and the heat dissipation wind channel is around the top cap bottom, and the direction is downward. The brake resistor generates heat due to the lack of an effective heat dissipation circulation path, so that hot air is concentrated in a large amount in the top cover, and a high-heat high-pressure area is formed. And secondly, the middle of the cabinet body air duct of the frequency converter cooling fan and the control cabinet is provided with a part of open space, and the frequency converter cooling fan and the cabinet body air duct are not effectively connected into a whole. Because the heat generated by the brake resistor is totally concentrated in the top cover, the formed high-heat high-pressure area has a resisting effect on the wind blown out by the fan of the frequency converter, only a small amount of wind enters the top area to form a small-flow wind flow path, and therefore the heat in the top area is less brought out from the wind channel of the top cover. And thirdly, the hot air part blown out by the frequency converter enters the inside of the control cabinet and moves downwards, so that the air inlet at the bottom area is sucked into the frequency converter again, the heat dissipation effect of the frequency converter is not ideal, and the heat forms dead circulation in the inner space of the control cabinet. Fourthly, high heat formed at the top is downwards conducted to the RTU, the multifunctional electric meter, the frequency converter and other equipment along with the metal of the cabinet body, and the equipment runs at high temperature and is very easy to burn out and deform, so that the equipment is damaged. Fifthly, the sealing performance of the control cabinet door is poor, rainwater is easy to enter, and components are damaged.
