Embodiment Construction

[0017] combined with figure 1 and figure 2 The power cabinet shown includes a housing 1 of the power cabinet, an electrical control unit 2 in the upper part of the housing 1, a circuit unit 3 in the lower part of the housing 1, and an underground The line through holes 4 communicate with the line slots, wherein the line unit 3 is provided with an exhaust fan 5 for exhausting air to the outside of the housing 1 . A partition 6 separating the electrical control unit 2 from the line unit 3 is arranged in the casing 1 . The electrical control unit 2 is provided with a drying box 8 . The electric appliance control unit 2 is provided with a hot air blower 7 .

[0018] The principle of use is that when there is a heavy rain in summer, the exhaust fan 5 is first turned on, and after the high-temperature and high-humidity air in the underground trunking flows into the power cabinet, most of the air is discharged out of the power cabinet under the action of the exhaust fan 5; At th...

Abstract

The invention relates to an electric appliance control device, in particular a power cabinet. The power cabinet comprises a power cabinet shell and an electric appliance control unit which is arranged in the upper half part of the interior of the shell; the lower half part of the interior of the shell is a line unit for accommodating lines; a line through hole which is communicated with an underground line groove is formed at the bottom of the shell; and the line unit is provided with an exhaust fan for exhausting air to the outside of the shell. With the power cabinet of the invention adopted, the problem of condensation in an existing floor type power cabinet which is communicated with an underground line groove in rainy days in summer can be solved, while, with the power cabinet of the invention adopted, condensation in rainy days in summer can be avoided.

Description

technical field [0001] The invention relates to an electric control device, in particular to a power cabinet. Background technique [0002] The following first explain the power cabinet and condensation in the present invention: [0003] Power cabinet: The power cabinet refers to the combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters, high-voltage cabinets, transformers, etc. The function of the power cabinet: 1. Supply power to the electrical equipment (provide power to the equipment); 2. Start and stop the electrical equipment (with a start and stop button); 3. Detect the operation of the equipment (set the signal indicator light, and have an ammeter and voltmeter) . [0004] Condensation: The composition of air can be regarded as composed of three parts: air, water vapor, and dust. Absolute humidity is the mass of water vapor contained in a unit of air at a certain pre...
