Problems solved by technology
[0003] The use of high and low voltage complete sets of equipment will appear in some extreme environments, such as severe cold conditions, which have extremely high requirements on equipment performance. Once the equipment is stopped or damaged due to too low temperature, it will cause economic losses, and it will also affect people’s lives. bring inconvenience
[0004] The shell structure of high and low voltage complete sets of equipment is generally an integral structure. Due to its large volume, it is not conducive to transportation before assembly. In the shell structure of high and low voltage complete sets of equipment, a heating device box is often used to heat the operating temperature of its internal components. The heating device box often occupies more space in the shell structure of high and low voltage complete sets of equipment, which is not conducive to the installation of internal components of the shell structure of high and low voltage complete sets of equipment;
[0005] At present, the heater device in the casing of the high and low voltage complete set of equipment has slow temperature diffusion when heating, the local temperature is high, and the heater is exposed without protection.
However, the existing technology has the following disadvantages: in certain seasons in areas with high humidity, condensation is likely to form in the power distribution cabinet due to rapid temperature changes, and water vapor deposits in the cabinet are likely to cause electrical short circuits and cause accidents

The invention discloses a high and low voltage complete equipment cabinet structure comprising a fixed placing base and an equipment body which is arranged on the upper end of the fixed placing base.A heating device box is arranged in the groove. The two sides of the heating device box are provided with air inlet opening through slots. The heating device box is internally provided with a cavity used for installing a fan. Heating wires are fixed in the middle opening of a rectangular plate. The middle part of the lower end of a cover plate is provided with an air inlet slot. The left and rightsides of the cover plate are provided with ventilating pipes of which the openings are upward. The upper ends of the ventilating pipes stretch into the gaps between the two side walls of the equipment cabinet and the protection plate. The heating wires perform heating after being electrified, the fan works and blows the hot air produced by the heating wires to the air inlet slot and finally to the gaps between the two side walls of the equipment cabinet and the protection plate through the ventilating pipes communicated with the air inlet slot so that the overall temperature in the equipmentcabinet can be enhanced, and the damage to the equipment in the equipment cabinet caused by the situation of excessively low temperature in the equipment cabinet can be prevented.
Description
technical field [0001] The invention relates to the technical field of high and low voltage complete equipment cabinet structure, in particular to a high and low voltage complete equipment cabinet structure. Background technique [0002] High and low voltage complete sets of equipment include switch cabinets, switchboards, control boxes, switch boxes and other electrical equipment. The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power...
