Embodiment Construction

[0020] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0021] see figure 1 As shown, an outdoor frequency conversion cabinet includes a cabinet body 1 for placing a frequency converter and a cabinet door 10 , and the cabinet door 10 is sealed on the side wall opening of the cabinet body 1 . In this embodiment, the cabinet body 1 and the cabinet door 10 are assembled into a cube, and the cabinet door 10 is one of the side walls of the cube that can be opened or closed. The cabinet body 1 is made of steel plates, and the joints of the steel plates are sealed. Sealing strips have been installed around 10, and the cabinet door 10 is closed, and the frequency conversion cabinet becomes a closed structure.

Abstract

The invention provides an outdoor frequency conversion cabinet which comprises a cabinet body for containing a frequency converter and a cabinet door. The cabinet door is arranged on a side wall opening of the cabinet body in a sealing and covering mode. The side wall of the cabinet body is oppositely provided with an air inlet and an air outlet. The outer side of the air inlet is provided with an air inlet protection hood, and the outer side of the air outlet is provided with an air outlet protection hood. The lower portion of the air inlet protection hood and the lower portion of the air outlet protection hood are provided with ventilation openings respectively. The ventilation openings are each provided with a baffle. By means of the technical scheme, the outdoor frequency conversion cabinet can be protected against the rain and snow, and effective heat dissipation is achieved.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical equipment used on-site for pumping wells in oil fields, in particular to an outdoor frequency conversion cabinet. Background technique [0002] In recent years, with the popularization and application of frequency converters in oil fields, many oil field pumping units have also installed frequency conversion control cabinets. The oil field production system is like a super large open-air factory, and most of the frequency conversion control cabinets are installed in the outdoor open-air environment. Facing the hot sun in summer, coupled with the large amount of heat generated inside the inverter, the internal temperature of the inverter cabinet is very high. Good heat dissipation conditions must be provided, otherwise the circuit will be aging, the electronic components will be overheated, and even catch fire , Seriously affect the service life of the frequency converter, according...
