How to discharge an electrolytic capacitor 1. For small lead aluminum electrolytic capacitors, just short-circuit and discharge them directly, but generally we don't recommend them. 2. For the horn-type electrolytic capacitor with a little larger capacity, you can make a 220v/60-100w bulb, or use a resistor to discharge slowly. 3. For bolt-type high-voltage and large-capacity electrolytic [...]
Reference News Network reported on December 17 that the US media said that the funds raised by Chinese companies in initial public offerings (IPOs) at home and abroad are unprecedented, accounting for nearly 40% of the total global IPOs, partly because the country was the first to overcome the epidemic. Chinese [...]
Fan start capacitor connection detection method Household electric fans use single-phase AC motors, so only one live wire and one neutral wire can work normally, but in order to protect the motor, an additional electric fan starting capacitor needs to be installed, which can avoid the time of starting The winding is burnt out because of [...]
International institutions are optimistic about China's economic development prospects Recently, the World Intellectual Property Organization released the "World Intellectual Property Indicators" annual report. The report shows that China has applied for 1.4 million patents in 2019, ranking first in the world. The number of patent applications in Asia accounted for nearly two-thirds of [...]
①When the power capacitors is operated for a long time under the environment of overvoltage, overcurrent, high temperature, etc., the insulating medium of the capacitor is aging and a large amount of gas is generated, which increases the internal pressure of the power capacitor. When the pressure is greater than the maximum [...]
