In the process of using the variable frequency power supply, the time is too long to avoid the need to maintain it, so that it can play the best product performance. The following uv frequency conversion power supply manufacturers will introduce you to the common sense of daily maintenance.
First of all, every operator responsible for maintenance must be familiar with the basic working principles, functional characteristics of the variable frequency power supply, and have basic knowledge of electrician operation. Before the inspection and maintenance of the variable frequency power supply, the total power supply of the equipment must be cut off; and the Chang light of the variable frequency power supply must be completely extinguished.
Before powering on the variable frequency power supply, check the temperature and humidity of the surrounding environment. Too high temperature will cause the variable frequency power supply to overheat and alarm. In severe cases, it will directly cause damage to the variable frequency power supply power components and circuit short-circuit; too much air will cause a direct short circuit inside the variable frequency power supply. When the variable frequency power supply is running, pay attention to whether the cooling system is normal, such as whether the air duct exhaust is smooth, and whether the fan has abnormal noise.
Generally speaking, frequency conversion power supplies with relatively high protection levels, such as: frequency conversion power supplies above IP20 can be installed directly, and frequency conversion power supplies below IP20 should generally be installed in cabinets. Therefore, how the heat dissipation effect of the frequency conversion cabinet will directly affect the normal operation of the frequency conversion power supply. Exhaust system, such as whether the fan rotates smoothly, whether there is dust and blockages in the air inlet, are places that cannot be ignored in our daily inspections. Whether the motor reactor, variable frequency power supply, etc. are overheated or smelly; whether the variable frequency power supply and motor have abnormal noise; whether the current display on the variable frequency power supply panel is too large or the current change range is too large, and whether the output UVW three-phase voltage and current are balanced.
In summary, doing a good job of routine maintenance of the variable frequency power supply will help extend the service life of the product and maximize its effectiveness.
