Frequency converter dustproof method

The frequency converter is a kind of electric energy controller, which can save energy and save electricity by using the frequency converter on many industrial equipments. However, the inverter also needs dustproof in the process of use. What is the specific dust-proof method? Below, Sinol Electric will give you a general introduction to the dust-proof method of the inverter.

1. Design a special inverter room

When the inverter used is large or has a large amount of power, a special inverter room can be designed. The door and window and cable penetration holes of the room are required to be sealed to prevent dust from entering. The air filter device and circulation passage should be designed to keep the indoor air flowing normally; the indoor temperature should be below 40 °C. Unified management is conducive to inspection and maintenance.

2. Install the inverter in a cabinet with a fan and filter unit.

When the user has no conditions to set up a special inverter room, you can consider making a frequency converter dustproof cabinet. Designed fans and filters to ensure adequate air flow in the cabinet. The user should check the fan regularly to remove dust from the filter net to prevent the temperature from increasing above the specified value due to insufficient ventilation.

3, choose the dustproof capacity of the inverter

There are many specifications and models of inverters on the market. When choosing, in addition to price and performance, the adaptability of the inverter to the environment should also be considered. Some inverters do not have a cooling fan and rely on their housing to naturally dissipate heat in the air. Compared with air-cooled inverters, although the volume is large, the sealing performance of the device is good, it is not affected by dust, the maintenance is simple, and the failure rate is low. Long working life, especially suitable for corrosive industrial gases and dust.

4, reduce the no-load running time of the inverter

In the industrial production process, the general-purpose frequency converter is usually powered on frequently, and the start/stop of the motor is controlled by the "forward/reverse/common" control terminal (or the button on the control panel) of the inverter. turn around. Some equipment may be stopped when the vehicle is on, and the fan is still running when the inverter is not loaded, which will absorb dust, which is unnecessary. During the production operation, the idle time of the inverter should be minimized to reduce the influence of dust on the inverter.

5. Establish a regular dust removal system

The user should determine the time interval for regular dust removal based on the influence of dust on the inverter. Dust removal can be done with a vacuum cleaner or compressed air. After dust removal, pay attention to check the rotation of the inverter fan and check if the electrical connection point is loose.
