Dehumidifier in basement power distribution room

Through a large number of field investigations, the dehumidifier technology in the distribution room in the basement shows that the power operation system environment such as the distribution room, substation and switching post is generally wet and waterlogged. This harsh electrical operation environment is extremely unfavorable to the service life of the indoor electrical equipment and the operating environment of the power system, such as: the switch cabinet is subject to moisture flash explosion, the distribution cabinet is subject to moisture, mildew and corrosion, and the distribution cabinet and distribution box are wet and dewy, Electrical short circuit of bus tray and damp water accumulation in cable trench are common

Then, how can we effectively solve such problems, make the electrical operating environment reach the best state, and reduce the hidden dangers of power system operation? For some mountain leaning areas or seaside substations, the humidity is high all the year round, and the condensation in the switch cabinet is serious. It is necessary to consider installing dehumidification and moisture-proof devices in the switch cabinet, such as dehumidifiers, air conditioners (with dehumidification function), heating and other facilities, which can speed up the removal of high humidity air according to seasonal characteristics, and ensure a good operating environment for the high-voltage switch cabinet

1. Install the temperature and humidity control device in the power distribution cabinet: after installing the temperature and humidity control device, the temperature and humidity controller will detect according to the humidity inside the power distribution cabinet. When the detected humidity is too high, the heating circuit will be started to let the heating plate work to prevent condensation

2. Installation of air conditioner: dehumidification is to use the low temperature condensation function of the air conditioner and refit it with the air conditioner. The condenser and evaporator can be placed separately in the same room. The evaporator should collect water to prevent secondary evaporation. The water collecting container should be equipped with a small water level switch to control a small water pump. When the water is accumulated to a certain extent, it can be pumped out and discharged. If the drainage is convenient, it can be directly connected to the drainage pipe. If it is necessary to control the room temperature, the condenser can be installed outdoors

3. Installation of dehumidifier: the dehumidifier fan is used to draw the moist air from the power distribution room, substation, switching station and other power operation system environments into the machine. At this time, the moisture in the air is condensed into water droplets through the heat exchanger, and becomes dry air to be discharged outside the machine. This circulation reduces the indoor humidity

◎ Precautions for model selection -- The dehumidification capacity and model of dehumidifier are scientifically calculated mainly according to the volume of the used environment space, the size of fresh air volume, the humidity requirements required by the space environment and other specific values. In addition, it should be noted that the relative humidity of the environment is related to the temperature of the environment. The higher the temperature is, the faster the humidity will evaporate. On the contrary, the worse the effect will be. Therefore, when configuring the dehumidifier, you need to select the type under the guidance of professionals, so that you can select the dehumidifier that is most suitable for you

Core tips: It can be seen from this that the importance of environmental governance in the power distribution room is self-evident. Through the monitoring and auxiliary governance of the operating conditions, environment, fire protection and security systems of the primary equipment in the power distribution room, the scientific management of the operating environment of the power distribution room (security, fire protection, water leakage, access control, fresh air, temperature and humidity, etc.) can be realized, and the failure and hidden trouble of the auxiliary equipment in the power distribution room can be found in time, Reduce economic losses and social impact
