The Spring Festival is a sign of the arrival of spring. Warm and humid air will follow. In the East China, South China, Bohai Rim, and even the Yangtze River areas, the cooled equipment is prone to condensation, dust accumulation, oil diffusion, acid and alkali corrosion, etc. In addition, there are rat, worm, and other homes on the equipment, in the power distribution cabinet, or in the control box. Therefore, each year after the Chinese New Year holiday ends at work, the water shortage, corrosion, rat, and insect cause power short-circuits. There are countless examples of electrical equipment damage, which brings users many unnecessary troubles. Facing this kind of situation, Yi Neng Xiao Bian reminded the majority of users that after a long vacation, we must attach great importance to the maintenance and inspection of the equipment.
1, do a good job of moisture-proof work, clean up the spot water stains, keep the environment of the power equipment dry, the inverter should pay attention to avoid exposure.
2, do a good job of maintenance and maintenance, è¶ shutdown maintenance, cleaning frequency conversion dust, clean frequency conversion air duct; good frequency conversion cable connector to prevent loosening, protective terminal cover to be covered, to ensure that the protective cable cover is not damaged to prevent rodents in the inverter settle down.
3, do a good job of anti-corrosion work, after the suspension of production to clean up the equipment on the acid and basic impurities, oil, effusion.
4. Check the work before power on. Before power on, check whether the electrical equipment including the inverter is dry. If there are traces of moisture, dry it by means of drying, lamp baking, etc., and measure the insulation of the input/output side. There is no short circuit phenomenon. Once again, special attention should be paid to the first time in the coming year, we must ensure that the frequency conversion is not affected by the tide in order to power on, especially the micro-corrosion environment of the chemical industry, and carefully check before power on. Corrosion is hydrophilic in many cases and causes short circuits most easily.
