Description
HVDC is a series of high-voltage DC capacitors for power electronics. The capacitors are intended for DC sources and general applications in electronic equipment, as well as for circuits in which large pulse currents occur: DC links of converters, energy storage and filter circuits, and pulse installations. Design. The capacitors are self-healing, use MKP (metallized polypropylene) technology and are of dry type. The capacitor elements are housed in a cylindrical aluminium case filled with a non-toxic, biodegradable solid filler based on vegetable oil. The case has a threaded M12 bolt for mounting and earthing. Discharge resistors are not fitted. The capacitor is equipped with an overpressure disconnection device; the lead wires must allow the top part to move by 20 mm for this protection to operate. Mounting is vertical only. Characteristics. The rated voltage is from 1.6 to 6 kV DC, the self-inductance is not more than 12 nH, the capacitance tolerance is ±5 %, the operating temperature is −25…+70 °C and the storage temperature is −40…+70 °C. The test voltage between terminals is 2 Un DC for 10 s, and between terminals and the case 2 Ui + 1000 V AC for 10 s. Tightening torques are 1 N·m for M4 terminals, 2 N·m for M6 terminals and 5 N·m for the M12 mounting bolt. For example, the 1.6 kV version with 10 μF capacitance has an RMS current of 12 A, a peak current of 3.5 kA, a diameter of 65 mm, a height of 85 mm and a mass of 0.35 kg. Standard IEC 61071. Applications: medium-power converters, traction and industrial drives, power supplies and pulse equipment.
