CONTACTOR SYSTEM FOR A FLUCTUATING DC POWER SUPPLY AND METHOD FOR STABILISING A CONTACTOR SYSTEM FED BY A FLUCTUATING DC POWER SUPPLY

摘要

Contactor system for a fluctuating DC power supply, comprising:a contactor (10) that comprises:- an electromagnetic coil (1),- a first and a second terminals (2, 4) to operate the electromagnetic coil (1) at a first voltage provided by the DC power supply, and- at least an additional terminal (5) located between the first and the second terminals (2, 4) connected to the DC power supply, the first and the additional terminals (2, 5) and the additional and the second terminals (5, 4) operating the electromagnetic coil (1) at a second or third voltage provided by the DC power supply equal or lower than the first voltage, anda measuring device (8) operating the contactor (10) from the first and the second terminals (2, 4) or from the first and the additional terminals (2, 5) or from the additional and the second terminals (5, 4).
