The XWF series resonant capacitor is used in AC high-voltage circuits, where the resonant capacitor (capacitor) is matched with the reactor (inductor) to form a series or parallel resonant circuit.
a) When using resonance, the changes in frequency, voltage, or current are used for scientific research or experimental equipment. Like an AC resonant transformer.
b) Form a low impedance channel or a high impedance channel for certain specific frequencies of AC voltage.
Main usage conditions and technical performance of XWF series resonant capacitors
a) Environmental temperature: -40 to+45 ℃.
b) Altitude: ≤ 1000m. When the altitude is higher than 1000m, please specify separately.
c) Divided into indoor and outdoor use.
d) The capacitance deviation is ± 8%.
e) The tangent of the capacitor loss angle (tg δ) is at 50Hz and rated voltage, tgδ≤0.2%。
f) The partial discharge performance of containers is divided into no partial discharge and no requirements.
Note: If there are special usage conditions, technical performance, parameters, requirements, etc., they can be negotiated separately.
3、 Structure Introduction
a) The shell is made of steel plate, insulated pipe or engineering plastic.
b) Inside the casing is the body, which is composed of capacitor elements connected in series and parallel.
c) The electrode plates of the capacitor are made of aluminum foil, and the dielectric between the electrodes is a polymer film or a composite of film and capacitor paper.
d) Capacitors undergo high vacuum treatment and are impregnated and filled with non-toxic, odorless, high-performance insulating oil.
