The role of starting capacitor
The role of starting capacitor Simply put, the capacitor is used to generate a phase difference, and the motor magnetic field is "asynchronous", and the motor rotates. A single-phase asynchronous [...]
Maintenance of power capacitors
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, [...]
How to solve the damage of reactive power compensation capacitor?
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 [...]
What factors affect the life of low-voltage power capacitors?
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 [...]
Reasons for the popularity of self-healing capacitors
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 [...]
How to test whether the capacitor is inserted reversely
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 [...]
Structural characteristics of aluminum electrolytic capacitors
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 [...]
How do different capacitor leakage current occur?
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 [...]
The role of X2 safety 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
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. [...]
