ABSTRACT:
A liquid-cooled power resistor contains at least one resistive conductor which is arranged in a closed housing directly in de-ionized water employed as the cooling liquid or coolant. The resistive conductor is advantageously secured in diaphragms which not only serve as holding facilities for holding the resistive conductor, but also deflect or turn the cooling liquid. The resistive conductor is normally connected to two terminal pins. There also can be used a third terminal pin which taps the center or mid-point of the resistive conductor, so that there are available two ohmic values of the power resistor. The power resistor ensures for an effective and uniform removal of heat or thermal energy and possesses a high thermal capacity. The arrangement has a low inductance. The power resistor is particularly suitable for the wiring of thyristors in static converter installations.
