Capacitor technical knowledge, principles and fundamentals
Power capacitor is a static reactive power compensation device. The maintenance of power capacitors is divided into the following situations: (1) Matters needing attention when handling capacitors Under normal circumstances, [...]
1. The breakdown of the internal components of the reactive power compensation capacitor is mainly caused by poor production technology and overvoltage. Solution: Choose a good quality compensation capacitor and [...]
Low-voltage power capacitors are the key equipment in distribution reactive power compensation, and power capacitors are a very "soft" component, which will reduce the service life of power capacitors under [...]
The self-healing capacitors uses a single-layer polypropylene film as the medium, and a thin layer of metal is vapor-deposited on the surface as a conductive electrode. When an excessively high [...]
Whether the capacitor is inserted reversely can be detected by image recognition or ICT For capacitors with polarity, such as electrolytic capacitors, tantalum capacitors, etc., it is absolutely not allowed [...]
The aluminum shell and the rubber cover are sealed to form an electrolytic capacitor. Structural characteristics of aluminum electrolytic capacitors as follows: (1) The working medium of the aluminum electrolytic [...]
The capacitor medium cannot be absolutely non-conductive. The capacitor is applied with a DC voltage, the capacitor will have leakage current（LC). Electrolytic capacitor The two poles of the electrolytic capacitor [...]
1. The role of X2 safety capacitor is conventionally anti-electromagnetic interference. It is generally connected in series in the circuit between the neutral wire and the live wire. It is [...]
Matters needing attention when using aluminum electrolytic capacitor Working temperature and ripple current 1. Make sure that the operating temperature and ripple current do not exceed the specified range. [...]
The difference between CBB capacitor and safety capacitor mainly includes three aspects: One: the difference in performance The main difference between safety capacitors and CBB capacitors is the outer packaging [...]
