Electric control cabinet for three box type smart-cooling oil field

Abstract

The invention relates to an electric control cabinet for a three box type smart-cooling oil field. The bottom of an inner cabinet and the bottom of an outer cabinet are fixedly installed on a lower cabinet. A heat dissipation opening is formed in the outer cabinet, and a heat dissipation hole is formed in the inner cabinet. Ventilation openings are formed in the four side walls of the lower cabinet, and the ventilation openings are provided with sliding cover plates capable of covering the ventilation openings. Through holes communicating the inner cabinet and the gap between the inner cabinet and the outer cabinet are formed in a top plate of the lower cabinet. A draught fan is arranged in the lower cabinet, and an outlet of the draught fan is connected with a horn opening with an upward opening and is connected with the top plate below the inner cabinet. A temperature control probe is arranged in the heat dissipation hole in the inner cabinet and is connected with an intelligent controller of the draught fan, and the draught fan supplies air to a cabinet body with a small air volume and a low speed. According to the electric control cabinet for the three box type smart-cooling oil field, a field working environment is adopted better, the influence caused by the climate on electric components and parts in the inner cabinet is reduced, at the same time, the air is supplied to the inner cabinet with the low speed and small air volume, the heat dissipation efficiency and the dustproof effect are improved, stable working environment is provided for the electric components and parts in the inner cabinet, and the rate of breakdown is lowered.

Description

technical field [0001] The invention relates to a cabinet of electrical equipment, in particular to a three-box type intelligent heat dissipation oil field electrical control cabinet. Background technique [0002] The electrical control cabinets used for pumping wells in oil fields are usually installed in the field environment, and the use environment is poor, especially in the oil fields in northern my country, which need to withstand the test of sandstorm weather, sun exposure, rain and snow weather, and extreme heat and extreme cold weather. At present, conventional electrical control cabinets generally include a box body and a box door. The box door is hinged on the front side of the box body, and electrical equipment is installed in the box body. Roof-shaped top cover, these conventional measures are difficult to effectively resist the impact of harsh environments on electrical components, electrical equipment, instruments, etc. installed in the electrical control cabi...

AI Technical Summary

Problems solved by technology

The above-mentioned exhaust and heat dissipation methods are not only ineffective, but also cause other problems, such as dust and other pollutants brought in from the air inlet, or dust entering through the gaps in the cabinet due to negative pressure air intake, It is easy to move upwards with the airflow and adhere to the surface of components or insulating parts to form dirt, causing creepage, pollution flashover and other safety accidents, posing safety hazards
