1) The air duct of the inverter cabinet should be planned reasonably, and the exhaust should be clear and smooth, so as to avoid the formation of vortex in the cabinet and the accumulation of dust in a fixed direction.
2) A protective top cover should be installed on the top air outlet of the inverter cabinet to avoid debris falling directly; The height of the protective top cover should be reasonable and not affect the exhaust air. A protective net should be installed at the air outlet next to the protective top cover to avoid flocculent debris falling directly.
3) If the exhaust method is selected next to the top of the inverter cabinet, it is necessary to install a protective net at the air outlet.
4) To ensure that the axial fan at the top of the inverter cabinet rotates in the correct direction (pumping outward), if the fan device is outside the top of the inverter cabinet, it is necessary to ensure that there is a satisfactory height between the protective top cover and the fan; If the fan is installed inside the top of the inverter cabinet, it is necessary to use anti-rebound bullet parts for the screws required by the device to avoid damage to the components and equipment in the cabinet caused by the fan falling off. Installing a plastic or rubber damping gasket between the fan and the cabinet can greatly reduce the noise caused by the fan sensation.
5) The front and back doors and other joints of the inverter cabinet should be sealed with gaskets or sealants to avoid dust entering.
6) All air inlets and wire inlet holes at the bottom of the inverter cabinet and side plate must be equipped with dust nets. Blocks the entry of flocculent debris. The dust filter should be planned to be detachable to facilitate sorting and maintenance. The mesh of the dust net should be small, which can effectively block fine flocculents (similar to the mesh of general household anti-mosquito and fly screens); Perhaps the appropriate grid scale should be determined according to the specific situation, and the junction between the dust filter and the inverter cabinet should be handled closely.

The cause of bearing noise in different situations of frequency converters - Reynolds
1. If the bearing is in good continuous rotation condition, it will emit a low whining or humming sound. Sharp hissing, squeaking and other irregular sounds often indicate that the bearing is in a bad continuous rotation condition. The sharp squeaky noise can be due to the formation of an inappropriately smooth ...

The inverter prepares the braking resistance factor – Reynolds
The preparation of the braking resistor of the inverter is mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the capacitor voltage being too high. Theoretically, if the capacitor stores a large amount of energy, it can be used to release it to drive the motor and avoid energy waste. However, the capacitance of the capacitor is ...

The inverter cannot adjust the frequency solution - Reynolds
In the course of inverter repairs, if there is no significant damage to the hardware and the maximum torque of the VFD is usually less than the torque of the load increase. It means that the load capacity of the frequency conversion speed control equipment has decreased significantly. So how do you deal with this?

The reason why the inverter burns the power supply inlet end - Reynolds
1. It is necessary to consider the touch and current size of the incoming terminal, if the terminal standard is small, perhaps the conductive function of the terminal is poor, which will directly cause the current carrying capacity of the terminal to be small and heated.
2. The inlet at the end of the inlet line must be pressed well and the like, if it is not pressed, it may cause ...
