Capacitance of the potential danger and security

Turn off the power supply after the capacitor charging, capacitance may still charge storage for a long time. This charge enough to cause electric shock, or damage connected instruments. A disposable camera flash module by 1. 5 v AA dry batteries, seemingly safe, but the capacitance may charge to 300 v, 300 v voltage produced by the electric shock can make people very pain, may even be deadly. Many of the aluminum electrolytic capacitor equivalent series resistance ( ESR） Low, because this is in short circuit generates a large current. Prior to servicing equipment with large capacitance, need to confirm the capacitance is discharge. For security reasons, all large capacitors to discharge before assembly. If on the substrate capacitor, which can be a discharge resistor in parallel beside the capacitor ( 泄漏电阻) 。 In normal use, the discharge resistance of the leakage current is small, will not affect other circuits. When in power, discharge resistor can provide capacitor discharge path. High pressure large capacitance in the terminal short-circuit during storage, to ensure that the storage charge have been discharge, because if the capacitance suddenly discharge during installation, the resulting voltage may cause danger. Large old-fashioned oil-immersed capacitor contain polychlorinated biphenyls (PCBS), 聚- 氯化联苯) , so discard need to properly handle, if not properly handled, polychlorinated biphenyls (PCBS) will enter groundwater, and pollution of drinking water. Polychlorinated biphenyls (PCBS) are carcinogens, trace will affect the human body. If the volume of capacitor, the risk is bigger, need to be careful. The new electronic components has not including polychlorinated biphenyls (PCBS).
