The cabinet is the final equipment of the power distribution system. The key is to protect, supervise and control the whole power circuit and manage it in a unified way. Distribution box is a reasonable arrangement of electromagnetic energy, so that the power circuit is easy to switch equipment. However, because it is a power supply circuit device, there is a high demand for prevention. Heat removal is one of the most important ways. This paper briefly introduces how to meet the heat removal regulations in the design and application of PLC control cabinet.
When applying the control cabinet, try to choose equipment with blinds on both sides. This should not be a complete separation. This kind of structure can promote air circulation and enhance heat conduction. If the customer in the summer application, should try to avoid long-term actual operation. Because the summer temperature is relatively high, the equipment itself will have a fever, long-term operation of the PLC control cabinet temperature will be very high, it is prone to problems.
The cabinet of the control cabinet is usually made of stainless steel plate. This information can avoid erosion and heat reflection. If customers use PLC control cabinet on time spray paint three-proof paint, can minimize the radiation heat, the effect of using PLC electrical cabinet will be better.
When using the control cabinet, the customer should try to ensure ventilation. They should also take effective measures to minimize the midday sun. If it weren't for the slate, they would have chosen a stronger location. Since the road surface is actually hotter in midsummer, it has been radiating heat to the ground rather than the heat of the slate floor. Smaller, can reduce the heat caused.
Many people can understand the general scale of operation of PLC control cabinet. However, the wide application of low-voltage distribution boxes is surprising. As we all know, PLC control cabinet is suitable for factories, mining, companies, large shopping malls, hotel restaurants, campuses, airports, seaports, hospital clinics, multi-storey buildings, day areas and other places.
The control cabinet application is also suitable for 50Hz communication. Fire pump control, submersible sewage pump control, fire exhaust fan control, centrifugal fan control and lighting PLC control cabinet are controlled by the power supply system below 500V. The control mode includes direct start control, star-delta step-down start control, auto-coupled step-down start control and frequency converter. Control methods such as operation control and soft start control can also use a lock switch and a fuse power switch as a lock break point.
In the hot climate, the public's power consumption increased significantly. Because of the overtemperature, the insulation of the wire will burn, releasing the foul smell of burnt skin and plastic. This phenomenon may be caused by the wire overtemperature. Once found, immediately turn off the button, and find the main cause of the wire overtemperature. In daily life, once the line is found to be aging and damaged, it must be replaced regularly to prevent future damage.
