The PLC control cabinet is the final level of equipment in the power distribution system. It mainly protects, supervises and controls the entire circuit, which is convenient for unified management. The power distribution cabinet is a kind of equipment that can reasonably distribute electrical energy and make the circuit easy to open and close. But because it is a circuit device, the requirements for the level of safety protection are very high. Heat dissipation is one of the most important methods. This article concisely introduces how to meet the requirements of heat dissipation in the design and application of PLC control cabinet.
When using PLC control cabinet, equipment with shutters on both sides should be selected as much as possible. The center should not be completely separated. This structure promotes air circulation and increases heat dissipation. Assuming that the user uses it in summer, it should try to prevent long-term operation, because the temperature itself is very high in summer, the equipment itself will also heat up, and the temperature of the PLC control cabinet for long-term operation will be extremely high, which may lead to shortcomings.
The cabinet body of the PLC control cabinet is generally made of stainless steel. This material protects against corrosion and heat reflection. Assuming that the user sprays the insulating paint punctually when using the PLC control cabinet, the heat radiation can be reduced as much as possible, and the role of the PLC control cabinet will be better.
When using a PLC control cabinet, the user also needs to insist on ventilation as much as possible. They should also use methods to prevent the midday sun as much as possible. Assuming that the sandstone was right or wrong, they would have chosen a better location because the temperature above ground is actually higher in the summer, and it always radiates heat to the ground rather than the heat on the sandstone ground. Relatively small, it can cut the generation of heat.
Many people can really understand the general planning of PLC control cabinets. But the widespread use of low-voltage distribution cabinets is surprising. We all know that the use of PLC control cabinet is suitable for factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, day areas and other occasions, communication 50Hz, rated operating voltage for communication 380V low-voltage power grid system. M, as power, lighting power distribution and motor control, suitable for rooms. Equipment for power distribution equipment on interior walls and exterior floors.
The use of PLC control cabinets is also suitable for communication 50Hz. Fire pump control, submersible pump control, fire fan control, fan control, lighting PLC control cabinet control are all selected power systems with voltage below 500V. The control methods include direct start control, star delta step-down start control, auto-coupling step-down start control and frequency converter. Control methods such as initiation control and soft initiation control can also be used as blocking switches and fuse switches.
In hot climates, people's electricity consumption increases dramatically. Because of overheating, the insulation of the wires will be burned out, announcing the stench of burnt skin and plastic incineration. This condition can be caused by overheating of the wires. The switch should be turned off as soon as it is discovered, and the cause of the overheating of the wire should also be identified. In everyday life, it is assumed that the line is found to be aging and damaged, and it is necessary to replace it in time to prevent damage in the future.
In order to prevent problems in the PLC control cabinet in the high temperature climate in summer, it is necessary to check the electrical wiring of the home or unit on time to eliminate hidden dangers in time. During equipment and construction, it is necessary to prevent scratches, abrasions, and bruises of conductor insulators. Pay attention to the robustness of the wire splices and the robustness of the insulating bandage. In places with special humidity, high temperatures or corrosive substances, it is forbidden to lay insulated wires in the open air. Casing wiring is selected. In dusty localities, wiring and insulation boards should be arranged on time to prevent oil pollution. Stop the indiscriminate pulling of wires. When the equipment wire, the wire of the corresponding section should be reasonably selected according to the load of the electrical equipment. Check the line fuse on time, choose the right one, and don't adjust the fuse at will, let alone replace the fuse with aluminum and copper wires. Punctually check whether the connection points on the line are robust and reliable, and no flammable materials should be placed near the line integrator. In order to better provide us with the above facilities, the PLC control cabinet is of great help to us.
