(1)设计专门的变频器室。当使用的变频器功率较大或数量较多时，可以设计专门的变频器室。房间的门窗和电缆穿墙孔要求密封，防止粉尘侵入；要设计空气过滤装置和循环通道，以保持室内空气正常流通；保证室内温度40℃以下。统一管理，有利于检查维护。 (1) design a special frequency converter room. A special frequency converter room can be designed when the power of the converter is larger or larger. The doors and Windows of the room and the cable shall be sealed to prevent dust invasion. To design air filtration and circulation channels to keep the indoor air in normal circulation; Assure indoor temperature below 40 ℃. Unified management, good for checking maintenance. (2)将变频器安装在设有风机和过滤装置的柜子里。当用户没有条件设立专门的变频器室时，可以考虑制作变频器防尘柜。设计的风机和过滤网要保证柜内足够的空气流量。用户要定期检查风机，清除过滤网上的灰尘，防止因通风量不足而使温度增高超过规定值。 (2) install the frequency converter in the cabinet with fan and filter unit. When the user has no condition to set up a special frequency converter room, can consider making the converter dustproof cabinet. Design the fan and screen to ensure sufficient air flow in the cabinet. The user should check the fan regularly to remove dust from the net and prevent the temperature from rising beyond the specified value due to insufficient ventilation. (3)选用防尘能力较强变频器。市场上变频器的规格型号很多，选择时，除了价格和性能外，还应考虑变频器对环境的适应性。有些变频器没有冷却风机，靠其壳体在空气中自然散热，与风冷式变频器相比，尽管体积较大，但器件的密封性能好，不受粉尘影响，维护简单，故障率低，工作寿命长，特别适合于有腐蚀性工业气体和粉尘的场合使用。 (3) choose a strong frequency converter. In the market, the frequency converter has many specifications and models. In addition to price and performance, it should also consider the adaptability of the inverter to the environment. Some inverter without cooling fan, by its nature of shell in air cooling, compared with air-cooled frequency converter, in spite of the large size, but the device sealing performance is good, is not affected by dust, easy maintenance, low failure rate, long working life, particularly suitable for corrosive gas and dust. (4)减少变频器的空载运行时间。通用变频器在工业生产过程中，一般都是经常接通电源，通过变频器的“正转／反转／公共端”控制端子（或控制面板上的按键），来控制电动机的起动／停止和旋转方向。一些设备可能是时开时停，变频器空载时风扇仍在运行，会吸附粉尘，这是不必要的。生产操作过程中，应尽量减少变频器的空载时间，以减小粉尘对变频器的影响。 (4) reduce the running time of the inverter. General converter in the process of industrial production, are generally not often connected to the power, through the inverter "forward/reverse/public end" control terminals (or a button on the control panel), to control the start/stop of the motor and the direction of rotation. Some devices may be time-off, while the fan is still running when the frequency converter is empty, and it will absorb the dust, which is not necessary. During the production operation, it is necessary to reduce the air load time of the frequency converter to reduce the influence of dust on the frequency converter.
