Frequency converter is a widely used equipment in modern factories. This is a very expensive new type of equipment, and the maintenance price of the inverter is also very expensive, so in the process of using the inverter, we should pay attention to the use of the inverter.
The physical environment is an aspect that has an important impact on the use of the inverter, according to the professional and technical personnel who repair the inverter and his repair experience, most of the problems of the inverter are formed by the logistics environment of the inverter, mainly including the following three aspects:
1. Working temperature: the inverter has a lot of electronic components, some of which will change the performance with the change of temperature, and some will even be damaged by the temperature, therefore, it is recommended to control the normal working temperature of the inverter between 0-55 °C, and some simple heating items should not be connected to the inverter.
2. Ambient temperature difference: If the ambient temperature changes too much, condensation will occur in the inverter due to the temperature difference. When the inverter is started, it is simply burned out due to short circuit inverter and other reasons, therefore, in the place where the temperature difference between day and night is large, put some desiccant in the inverter, which will greatly remove condensation.
3. Corrosive gases. The internal electronic components of the inverter are not corrosion-resistant, and should not touch corrosive liquids and solids, but corrosive gases can also cause damage to the components, so it is necessary to prevent excessive contact between corrosive gases and inverters.

Delixi spare parts replacement cycle
1. Cooling fan (2-3 years)
As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally a short-service life accessory, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.

The difference between air switch and leakage protection switch - Delixi
(1) The function is different.
An air switch is a kind of circuit breaker that maintains "something", which can maintain the safety of the entire household wiring and appliances, and avoid the overheating and burning of the wires.
The leakage maintenance switch is a kind of circuit breaker for maintenance personnel, which can block the circuit in time when leakage is carried out to avoid the danger of electric shock.

The structure of the inverter - Delixi
The main circuit is the power conversion part that supplies the voltage regulation and frequency modulation power supply to the asynchronous motor, and the main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source into a communication inverter, and the filter of the DC loop is the capacitor. The current type is to convert the DC of the current source into a communication ...
