The invention relates to a DC high-voltage electrical installation comprising a switching device (22) for switching an electric current in the main circuit (24), and a method for controlling the closure of a switching device in such an installation, characterized in that the installation (23) includes a controlled variable resistor system (26) making it possible to modify the resistance value of the resistor system (26) seen by the current flowing through the main electrical circuit (24), said resistance value taking at least three distinct values: high, a lower value, and at least one nonzerointermediate value comprised between the high value and the low value. The installation includes a coordination device (32) making it possible to control switching times (T1, T2) of the resistance values of the resistor system (26). 本发明涉及一种包括用于切换主电路(24)中的电流的开关器件(22)的直流高压电气设备以及一种用于控制这种电气设备中的开关器件的闭合的方法，特征在于，所述电气设备(23)包括受控可变电阻系统(26)，使得可以改变电阻系统(26)的由流经主电路(24)的电流所见的电阻值，该电阻值取至少三个不同的值：较高值、较低值以及至少一个包含在较高值和较低值之间的非零中间值。所述电气设备包括协同器
