Device for neutralizing an electric switching unit |
摘要 |
The invention relates to a device for neutralizing an electric switching unit. One or several power poles, each of which is provided with movable contacts separable form fixed contacts are actuatable between opened and closed positions by an actuator for switching-on an electric charge. A mechanical actuating device interacts with the movable contacts. It is used for actuating a device for neutralizing the electric switching unit by switching-off the control electric circuit thereof when the wear degree of pellets is greater than a predetermined threshold. The control circuit is switched-off, for example, by cutting a wire thereof. An electric switching unit is provided with the device. |
