First of all, when placing electrical appliances, try not to place the appliances in the center of the direct sunlight or in the dim corners that are not conducive to heat dissipation, especially refrigerators, color TVs, etc., but should be placed in a well-ventilated and ventilated environment to facilitate good Cooling.
Secondly, when using electrical appliances, especially high-power appliances, do not start frequently, and do not let the electrical appliances work under high current conditions for a long time. A hot external environment and prolonged overheating can damage components, at least shorten the life of the appliance. In addition, do not use the appliance in the event of frequent power outages such as excessive voltage or low voltage, as it may damage the appliance due to working under such conditions.
Third, the dust inside the electrical appliance should be cleaned up frequently, and it should be kept clean. Because the dust is too thick, it is not conducive to heat dissipation. For example, the accumulation of dust inside the TV not only affects the viewing effect, but may cause problems; too much dust in the filter of the air conditioner will affect the cooling efficiency, increase the power consumption, and shorten the life of the device.
Fourth, the summer air humidity is high, and citizens must pay attention to avoid the occurrence of electric shock accidents when using electricity. Moreover, in summer, the human body is sweaty, the skin resistance is reduced, and the clothes worn are weak, and the body is exposed to a large part, which increases the timing of electric shock. Therefore, the public must not use their hands to move the running electrical appliances, such as desk fans, washing machines, televisions, etc. To move, open the switch and remove the plug. If it is necessary to repair electricity, wear insulated shoes and gloves. For appliances that are frequently used in summer, such as water heaters, table fans, washing machines, etc., some measures should be taken to avoid electric shock. For example, the electric pen can often be used to test whether the metal casing can be charged, and the leakage switch can be installed. In addition, it is necessary to strengthen the groups that are weaker in self-maintenance, such as caring for children, to prevent them from causing tragedies due to the singularity of touching the electrical appliances.
Finally, if you encounter the situation of electrical water immersion, you should first cut off the power supply, that is, pull off the main switch or fuse to avoid accidents caused by water ingress and insulation damage. After the power is turned off, the appliance that may be immersed in water is moved to the boring center to prevent the insulation from immersing in water and affecting future use. If the electrical equipment has been immersed in water, the possibility of insulation is damp. Before using it again, it is necessary to test the insulation resistance. It can be used only when the request is reached. If the request is not reached, the insulation should be stopped and dried until the insulation is good.
