Although the frequency converter is installed independently outside the HVLS Fans, as the fan control system, it can be said to control the start and stop of the entire Hvls Ceiling Fans, and its role cannot be ignored. Especially in hot weather, rainy days, and crowded places, Hvls Ceiling Fans will be used frequently and for a lot of time. Then the more times the inverter is used, the inverter may overheat, causing the HVLS Fans to fail and no longer be used. Regarding inverter overheating, how should we solve it?
According to most research phenomena, a large part of the failure of the inverter is due to the increase in temperature, and its service life decreases with the increase in temperature. The reasons for the failure of Hvls Ceiling Fans caused by overheating of the inverter are as follows:
1. The inverter is composed of countless electronic devices, which will generate a lot of heat when working. Especially when the IGBT works at high frequency, it will generate more heat. If the ambient temperature is too high, the temperature of the internal components of the frequency converter will also be too high. In order to protect the internal circuit of the frequency converter, the frequency converter will report a high temperature fault and stop the machine.
2. When the air duct of the frequency converter itself is blocked or the air duct of the control cabinet is blocked, it will affect the internal heat dissipation of the frequency converter, causing the frequency converter to overheat and alarm.
3. The Hvls Ceiling Fans of the inverter is broken, and a large amount of heat accumulates in the inverter and cannot be dissipated.
4. When the load carried by the frequency converter is too heavy, excessive current and a large amount of heat will be generated, and the frequency converter will overheat and alarm.
Understanding the problem of HVLS Fans overheating can help you directly prescribe the right medicine. "Solving the heat dissipation of the frequency converter is the key. The operating temperature of the frequency converter usually needs to be in the range of -10-40, preferably around 25. Whether the frequency converter is overheated can be measured with infrared Use a thermometer to detect whether the heat sink is overheated or has a peculiar smell, and check whether the inverter has an alarm display of operating failure. The inverter has certain requirements for the surrounding temperature. Ventilation and heat dissipation of the installation site of the inverter should be strengthened to ensure that the surrounding air does not contain too much Dust, acid, salt, corrosive and explosive gases, all frequency converters should be installed vertically, keeping a certain distance from surrounding barriers.
In order to prevent foreign objects from falling on the air outlet of the frequency converter and blocking the air duct, it is necessary to install a protective mesh cover above the air outlet of the frequency converter, and clean the Hvls Ceiling Fans and air duct regularly to prevent clogging. The Hvls Ceiling Fans installed in the control box is the main means of heat dissipation in the inverter and will ensure the normal operation of the control circuit. If an Hvls Ceiling Fans operates abnormally or becomes damaged, it should be replaced immediately. Reduce the load or increase the capacity of the inverter. Regularly check the operating status of the frequency converter, whether the voltage and current values are within the normal range, and reduce the load of the frequency converter or increase the capacity of the frequency converter.
