As we all know, the service life of a product is determined by its design life, and electrical products are no exception. No product can be “Wan Nian Prisonâ€. Since it enters the consumer market, the value of use as a commodity attribute will gradually be reflected in actual use. However, the functions, usage environments, and frequency of use of various household appliances vary, and it is decided that the design of these products is not the same.

For example, the service life of a color TV is 10-15 years, which is mainly determined by the current production level of the color picture tube and the service life that can be achieved. The standard stipulates that it is not less than 15,000 hours, and it takes exactly 10 years to watch TV hours per day. If the actual life of the color tube is 20,000 hours or longer, the life of the whole machine determined by this can be extended to more than 10 years.
Another example is a refrigerator, which usually has a service life of 10 to 5 years, which is determined by the life of its key component, the compressor. Since the refrigerator is an electrical appliance that works all the year round, the requirements for the compressor of its heart component should be stricter. However, due to the over-age use of home appliances, the dangers of household appliances, fires, explosions, etc. are also common. Therefore, we must be familiar with the service life of home appliances to avoid danger. So what is the life expectancy of common appliances? Below, interested friends may wish to take a look.

Rectifier bridge is to seal the rectifier tube in a shell. Points full bridge and half bridge. The full bridge connects the four diodes of the connected bridge rectifier circuit together. The half bridge is half of four diode bridge rectifiers, and two half bridges can be used to form a bridge rectifier circuit. One half bridge can also be used to form a full-wave rectifier circuit with a center-tapped transformer. Select a rectifier bridge to consider. Rectifier circuit and operating voltage.
