Why is the temperature and humidity controller of the low-voltage cabinet? The application field of low-voltage cabinet is very wide, high-voltage switchgear should be one of the key electrical equipment and equipment for electromagnetic energy production scheduling and transportation, there will be some simple reasons to form high-voltage switchgear hot in specific work, low-voltage cabinet I remind you, at this time, we should maintain low-voltage cabinet in time, so as to prevent things from happening.
An important factor that jeopardizes the smooth operation of the low-voltage cabinet is the temperature and humidity in the high-voltage switchgear. When the environmental humidity of the high-voltage switchgear is large, the flame retardant function of the insulator in the high-voltage switchgear decreases, but when the flame retardant function of the insulator decreases, the insulating material made into the insulator digests and absorbs the moisture of the gas a lot, resulting in the further decline of its insulation function, and so on, it will fall into a dead loop, and finally form the insulation layer of the insulator is destroyed, and the high voltage conductor is charged and discharged according to the voltage of the insulator to the ground, the short-circuit fault, and the short-circuit trip damage the machinery and equipment, which seriously endangers the smooth operation of the power grid and the machine.
Why does the low-voltage cabinet use a temperature and humidity controller?
1. If the high and low voltage switchgear is in the south, the temperature is high in summer, coupled with the high humidity of the environment, and the internal structure of the box blocks the operation of the switch and other products to form heat, which can easily lead to safety incidents.
2. If the low-voltage cabinet adopts a temperature controller that can make all kinds of electric control boxes work under certain conditions, such as low temperature in the northern winter (usually minus 5 °C-30 °C), all kinds of household appliances are delivered and used immediately, and the damage is relatively large, the control board first works the electric heater to make the ambient temperature of the box suitable for the working environment of household appliances, so as to reduce common faults and add the service life of the product.
3. The temperature and humidity controller is used to overcome the problem of condensation. The problems that lead to safety issues such as high and low voltage cabinets, central cabinets, and terminal boxes are condensation and stains. If a long period of dense fog will cause the power to be turned off in the line, and there will be a problem with the inspection after a long time, the main reason for the inspection is the formation of condensation.
Assembling of low-voltage cabinets
1. The base of the low-voltage cabinet is made and assembled
The base of the low-voltage cabinet is generally made of channel steel, and the steel specification is determined according to the size and net weight of the low-voltage cabinet. The channel steel is leveled and straightened before cutting.
2. Low-voltage cabinet unpacking inspection
Before the construction of the low-voltage cabinet, it is necessary to unpack and check the certificate of conformity and product manual, and then check whether the low-voltage cabinet is intact, and then fill in the key content in the "unpacking record of machinery and equipment".
3. Assemble low-voltage cabinets
The low-voltage cabinet is smoothly installed on the foundation channel steel, the anchor bolts between the cabinets are tightened, and the ground leveling and levelness are welded together with the foundation channel steel, and the electrical cabinet has to use 6mm soft copper wire and grounding trunk necklace as grounding protection.
