Y capacitors are general equipotential connected capacitors during the two and bottom lines of the power line, usually presented by pair. In view of the limitation of leakage current, the value of Y capacitor can not be too large, usually X capacitor is UF stage Y capacitor is n F stage. Y capacitor

Ceramic capacitors were extruded into circular tube and flat circle by high capacitance rate capacitor barium titanate ceramic. Silver plating was made on ceramic by baking method. It is also divided into high frequency porcelain and low frequency porcelain, two kinds. High-voltage ceramic capacitor

Bias To work more efficiently, transistors or tubes need to be biased correctly. That is to say, to control the electrode-base, gate or gate-there must be a specific voltage or current. The resistor network is used to accomplish this. Different circuits require different bias levels. The bias of a R

As we all know, any electrical element has resistance, and none is a pure conductor. One might ask why the resistor is added to the circuit to reduce the current. Don't resistors consume power as heat? Is the efficiency of the circuit less efficient than before the resistor is not added? Yes, the re

Treatment To prevent these from happening, a hollow reactor can be serially connected in each phase of the compensating capacitor bank to limit the current. The synthetic reactance of the capacitor circuit becomes inductive reactance for the high order harmonics. The third harmonic is short-circuit

The existence of harmonic currentThe high power SCR rectifier is used as the DC power supply of rotary kiln and the compensation screen in parallel operation. The thyristor connected to the power grid plays the role of a high order harmonic generator objectively, which will cause the waveform distor

Cause analysis and treatment. 1. High ambient temperature. The reactive power compensation panel is installed in the 400V switch room. There are 8 switchgear cabinets in the room, but the area is only 30m2. The opposite is the SZ7-800kVA 35kV/0.4 transformer room. The overall ventilation conditions

I. improper selection of current in rangeImproper selection of current in the range, resulting in more locations are DC maintenance and simple harmonic vibration part. If the essential current value is larger than the current value allowed by the thin film capacitor, it will form the film capacitanc

As a widely used varistor, overvoltage protected varistor is often used to protect thyristor rectifier. How should we choose a suitable over-voltage protection varistor? In general, the 3kA varistor model is usually used for surge absorption of electrical equipment, while the 5kA resistor model is m

Capacitor withstand voltage: an electrical voltage, that is, a voltage at which an electrical or electronic component can function normally, above which the component cannot function properly, and the ceramic chip capacitor will be broken down once it exceeds its voltage value. It's not working. Cap
