parallel capacitors is a kind of reactive power compensation equipment, usually high-voltage centralized compensation is used to compensate the reactive power on all circuits and transformers on the power supply side of the low-voltage busbar of the substation. In use, it is often combined with on-load tapping transformers to improve the power quality of the power [...]

The difference between series and parallel capacitors is: different composition, different current paths, and different disconnection. 1. Different composition 1. Series connection: Series connection is to connect the components one by one. 2. Parallel connection: Parallel connection consists of connecting components in parallel. Two, the current path is different 1. Series connection: In the series circuit, [...]

coupling capacitor, also known as electric field coupling or electrostatic coupling, is a coupling method due to the existence of distributed capacitance. Coupling capacitors make the two systems of strong and weak currents coupled and isolated by capacitors, provide high-frequency signal paths, prevent low-frequency currents from entering the weak current system, and ensure personal safety. In [...]

paper capacitors use special capacitor paper as the medium, aluminum foil or tin foil as the electrode and wound into a cylindrical shape, then connect the lead, and then pass the staining treatment, and it is made of shell packaging or epoxy resin potting. Its structure is shown in the figure. Paper capacitors have the following [...]

Variable capacitors can be divided into air dielectric variable capacitor and solid dielectric variable capacitor according to their dielectric materials. 1. Air dielectric variable capacitor The electrode of the air dielectric variable capacitor is composed of two sets of metal sheets. Among the two sets of electrodes, the fixed set is the stator, and the rotatable [...]
