Problems solved by technology

[0002] The high-voltage power distribution room has strict requirements on the indoor temperature and humidity. When the indoor temperature is too high, it will cause abnormal operation of the equipment and easily cause the switch to trip due to high temperature. In addition, the humidity in the high-voltage power distribution room is too high. It will cause indoor metal equipment to be damp and rust, switch equipment will cause short circuit, and even damage indoor facilities

Embodiment 1

[0049] As shown in the accompanying drawings, a cooling and dehumidification method for a high-voltage power distribution room of this patent includes the following steps:

[0050] A: Sensor group installation: install outdoor temperature sensor 1 and outdoor humidity sensor 2 outside the high-voltage power distribution room, and set indoor temperature sensor 3 and indoor humidity sensor 4 inside the high-voltage power distribution room;

[0051] B; control group installation: the output end of A / D converter 5 is connected to single-chip microcomputer 6, the output end of button unit 8 and the input end of display unit 9 are connected to single-chip microcomputer 6, the input end of single-chip microcomputer 6 and drive circuit 7 connect;

[0052] C: The connection between the sensor group and the control group: connect the outdoor temperature sensor 1, the outdoor humidity sensor 2, the indoor temperature sensor 3 and the indoor humidity sensor 4 to the input end of the A / D c...

Embodiment 2

[0075] For a high-voltage power distribution room, the temperature is required to be below 30°C, the humidity is required to be below 40%RH, the temperature margin is 5°C, and the humidity margin is 5%RH. Use this device to control the temperature and humidity of the high-voltage power distribution room. Control; when the outdoor temperature of the high-voltage power distribution is 35°C and the humidity is 50%RH, while the temperature inside the high-voltage power distribution room is 40°C and the humidity is 60%RH, the device first controls the dry and wet gas port switching device 13 to close the dry gas port , the dehumidifier air intake switching device 14 closes the indoor air inlet, then starts the explosion-proof axial fan 10 to replace the indoor and outdoor air, and starts the dehumidifier 12 to directly dehumidify the air entering the room. When the indoor and outdoor air temperatures are balanced, Then the device controls the explosion-proof axial flow fan 10 and th...

Abstract

The invention relates to a high-voltage power distribution room. By adoption of a method, working time of an axial flow fan, an air conditioner and a dehumidifier can be given an overall consideration, the working efficiency of the dehumidifier can be improved, and energy conservation and emission reduction can be realized under the premise of ensuring that the temperature and humidity in the high-voltage power distribution room are in a normal state. When external air enters the high-voltage power distribution room, and if the outdoor humidity is greater than indoor humidity, a single chip microcomputer controls dry and wet air opening switching equipment to close a dry air opening; dehumidifier air inlet switching equipment closes an indoor air inlet opening, and meanwhile, air entering the room is dehumidified; if the outdoor humidity is lower than indoor humidity, the single chip microcomputer controls the dry and wet air opening switching equipment to close a wet air opening, to enable external air to directly enter the high-voltage power distribution room from the dry air opening; and if the air humidity in the high-voltage power distribution room exceeds a normal range, the single chip microcomputer controls the dehumidifier air inlet switching equipment to close an outdoor air inlet, and meanwhile, the air in the room is dehumidified, so as to enable the air humidity in the high-voltage power distribution room to be lowered to the normal range.

Description

technical field [0001] The invention relates to a high-voltage power distribution room. Background technique [0002] The high-voltage power distribution room has strict requirements on the indoor temperature and humidity. When the indoor temperature is too high, it will cause abnormal operation of the equipment and easily cause the switch to trip due to high temperature. In addition, the humidity in the high-voltage power distribution room is too high. It will cause indoor metal equipment to be damp and rust, switch equipment will cause short circuit, and even damage indoor facilities. [0003] In the dry weather conditions in the north, the humidity in the high-voltage power distribution room will exceed the humidity requirement only in a very small number of times. Not high enough. [0004] Therefore, we have designed a cooling and dehumidification energy-saving device for high-voltage power distribution room, which mainly focuses on cooling and assists with dehumidific...
