Do distribution devices and electrical circuits face issues related to heat prevention and cooling in hot weather conditions?
Thread Content
It’s that time again when the heat is unbearably intense; the temperature has reached 40 degrees Celsius these past two days. We have started adding axial flow fans on site to provide forced ventilation and cooling for the equipment and electrical installations. I used to think that power distribution and supply facilities were designed with extreme weather conditions in mind, ensuring they could operate normally. However, contrary to what is hoped, some remedial measures have to be taken every year at this time, otherwise problems will arise. Well, a few days ago, the lack of proper ventilation caused some devices to trigger over-temperature alarms. Why aren’t these problems solved during the design phase, and why do we have to implement some temporary measures on site at this point? These temporary measures have created additional risks due to poor management or even lack of standardization. Is there a better solution?
That makes a lot of sense; various operating environments should be taken into account during the planning stage, but this could result in higher investment costs； Considering cost-effectiveness and in order to reduce investment, forced air cooling can be used during periods of high temperatures.
Some companies install air conditioning in the distribution rooms to maintain the operating temperature of electrical equipment and improve the stability of its operation; generally, additional design work is carried out before a project is put into operation to optimize the configuration in this area.
Recently, the temperatures have been high, yet the electrical engineering department has imposed certain restrictions on power usage for production purposes. I also want to remind them to improve their facilities, as ensuring a stable power supply is what really matters
In the design of electrical distribution rooms in the petrochemical industry these days, HVAC systems are included; air conditioning is provided to maintain specific temperature and humidity levels, thereby ensuring the stable and reliable operation of electrical equipment. Primarily, motors in the field experience high temperatures due to exposure to high heat and heavy loads; for low-voltage, high-power motors, designs such as reinforced end caps can be considered at the time of manufacturing to increase the heat dissipation area.
For air-conditioning systems, whether portable or central, investment is necessary; the cooling capacity must be sufficient. The air-conditioners should be cleaned regularly, and inspections should be carried out daily. Keeping the temperature within 30 degrees Celsius is a safe option.
