摘要： The invention relates to an operating mechanism for opening and closing at least one contact, which operating mechanism comprises, a base frame, a bridge body movable relative to the base frame between a closed position and an opened position, a rod mechanism of a first and a second link, a cam arranged on a shaft, a locking lever fixedly arranged with one end to the first link and moves with the first rod between a locked position and an unlocked position, a control shaft having a D-shaft portion with a flat surface portion and a semi cylindrical surface portion, and a lock position, in which the path of the second end of the locking lever intersects with the circumference of the cross-section of the D-shaft portion.

摘要： A switch for medium voltage applications is provided. The switch comprises a vacuum interrupter having a fixed contact, a movable contact movable in a first direction to and away from the fixed contact between a closed position and an open position, and a drive rod arranged to the movable contact for moving the contact between the closed position and the open position. The switch further comprises a changeover switch having a first terminal body, a second terminal body, an elongated pole body, and an operating rod. The elongate pole body is hinged with a first end to the first terminal body and rotatable between a connected position in which the second end of the pole body is in direct electrical contact with the second terminal body and a disconnected position in which the second end is disconnected from the second terminal body.

摘要： Sensor part for installation in medium-voltage cable compartments, which sensor part comprises a voltage divider based on the capacitive divider principle, which voltage divider comprises: —a first capacitor, comprising an elongate primary conductor wrapped in a dielectric material and an elongate conducting shield arranged around the dielectric material, which first capacitor has a first capacitance rating; —a second capacitor, having a second capacitance rating, which second capacitor further comprises a first lead conductively connected with the conducting shield of the first capacitor and a second lead conductively connected to a common reference, such as earth; —a voltage output line, conductively connected with the conducting shield of the first capacitor; wherein the second capacitance rating is larger than the first capacitance rating, so that when during use the primary conductor is conductively connected with a live circuit carrying an alternating current, a measurement of a voltage between the common reference and the voltage output line can be taken as a ratio of the voltage between the live circuit and the common reference.
