The microcomputer harmonic elimination device is a resonance elimination device which integrates protection, monitoring, control, man-machine interface and communication printing. The working environment of microcomputer harmonic elimination should meet the requirements of long-term safe and stable operation and routine maintenance.

The relative humidity of the application environment of microcomputer harmonic elimination device: 90% (25 ℃), 50% (40 ℃). When the humidity is too high, the micro-computer harmonic elimination is affected by moisture. Firstly, the insulation performance of the device decreases and the insulation aging is accelerated. The moisture in the air adheres to the surface of insulating material, which reduces the insulation resistance of microcomputer harmonic elimination equipment. According to the current dielectric theory, with the increase of environmental humidity, the conductivity, relative permittivity and dielectric loss tangent of dielectric increase correspondingly, and the breakdown field strength decreases.

The working environment temperature requirement of microcomputer harmonic elimination is: - 10 ℃～ 50 ℃. If the ambient temperature is too high, it will also affect the microcomputer harmonic elimination. The internal equipment of the intelligent microcomputer harmonic elimination operation has a certain temperature. If the ambient temperature is too high or the air flow is poor, the heat of the equipment can not be dispersed in time, which will lead to the equipment burning out. If the environment is too low, the internal electronic equipment will not be sensitive.

The installation and use place of microcomputer harmonic elimination device and the air shall not contain the medium and gas with explosion risk, corrosivity and insulation damage. The installation site must have wind, rain, sand, dust and other facilities. In the overall layout design, the intelligent microcomputer harmonic elimination device should also be arranged in the area with relatively good environmental conditions.
