1.To deal with the abnormal operation condition in time, it is found that the shunt capacitor has abnormal conditions such as blooming, joint heating, serious oil leakage and so on during operating, so it must be withdrawn from operation. For the malignant accidents such as oil injection, fire, expl

No polarity, high insulation impedance, excellent frequency characteristics (wide frequency response, and small dielectric loss), Based on the above advantages, thin film capacitors are widely used in analog circuits.Especially in the intersecting part of the signal, it is necessary to use capacitor

Chinese name for CBB capacitors:, usually followed by two numbers, such as CBB60/CBB65. 0 and 5 are the CBB film capacitor serial code rule: ( 0: axial extraction; 1: radial extraction; 2: DC voltage; 6: ac voltage; 8: DC high voltage)Common specifications in the CBB capacitor market areCBB11 CBB12

Unit of capacitance1F=1000000μF1μF=1000nF=1000000pFThe basic unit of resistance is: F, in addition , μ F, pF, and a less used unit, that is,: nF. Because the capacity of capacitance F is very large, we usually see the units of μ F, NF, PF, rather than units of F. The conversion between them is as fo

Classification and function of capacitorsElectric capacitors are composed of two metal poles with insulating materials (dielectric) in the middle. Because of the different insulation materials, the types of capacitors are also different.According to the structure can be divided into: fixed capacitan

When the capacitor is put into operation, the operating indicator lamp is in flicker state. If overcurrent tripping occurs in a very short time, the clamp ammeter is used to measure the running current of the capacitor in time. If the current value exceeds 1.35 times the rated current. It indicates

The protector working power supply shall be in accordance with the nominal voltage. Protector terminal wiring should be correct and in good contact. Periodic inspections should be carried out to ensure reliable operation. After the protector giving instructions, you must carefully observe the type o

Power capacitor protector composes the power capacitor control system along with Switch capacitor contactor, reactive power compensation controller, fuse and so on, which is mainly used as a protector in power capacitors and compensation circuits When overcurrent, short circuit, inrush current, harm

Metal film capacitors and other capacitors have no loss in theory, but in fact the loss of metal film capacitors is affected by many factors, such as the voltage applied on both ends of the capacitor.Loss refers to the loss of energy caused by the heat emitted by the capacitor in the process of work

The self-healing of so-called thin-film capacitor self-healing refers to the capacitor in the case of having defects or under clicking through, the capacitor can return to normal situation called self-healing.The cause for this phenomenon is that when the dielectric of the film capacitor is defectiv
