摘要： Combined high voltage discharging and grounding device with a discharging unit with a first electric contact and a first counter-contact as well as a grounding unit with a second electric contact and a second counter contact. The first electric contact and the second electric contact are provided on a movable member which is movable by way of a drive along a path of movement from an open position to a close position. An electric contact between the first electric contact and the first counter-contact is established in an intermediate position between the open position and the closed position of the movable member when closing the discharging and grounding device in an operating state of the discharging and grounding device while the second electric contact is electrically still disconnected from the second counter contact.

摘要： A scalable earthing switch that incorporates a torsion spring to effect rapid closure of the switch. The torsion spring is supported coaxially about a rotatable shaft on which contact blades are mounted resulting in compact design. The blade contacts are separated axially along the length of the shaft by one or more spacers. By using difference size spacers the distance between adjacent blade contacts can be changed and, thus, the earthing switch can be easily scaled for different applications. A latching (detent) mechanism is provided for latching the switch in an open position.

摘要： A locking device for unipolar breaker is remote-controlled: the device surrounds a breaker blade and adds to a pivoting-base of the blade a T-shaped piece which prevents the closing of the blade. The T-shaped piece comprises a wide web and two wedge points. The wide web is of a reversed U-shape comprising wings that are locked together by a latch placed inside one of the wings and operated by a key. The latch cannot be triggered too easily so it will not start by itself. To trigger the latch, a key has to be inserted into a casing located in a wing. This casing holds a disk with scarf-joints while the key has a disk with grooves, the combination of scarf-joints and grooves allowing various combinations. The key is located at the end of a gaff, so that only one user may lock or unlock the switch.
摘要翻译：用于单极断路器的锁定装置是远程控制的：该装置围绕断路器叶片并且将叶片的枢转底座增加以防止叶片关闭的T形件。 T形件包括宽幅和两个楔形点。宽幅是由U形构成的反转U形，其中翼部通过位于一个翼内并由钥匙操作的闩锁锁定在一起。闩锁不能太容易触发，所以不能自动启动。要触发闩锁，必须将钥匙插入位于机翼中的外壳中。该外壳保持带有围巾的盘，而钥匙具有带槽的盘，围绕接头和槽的组合允许各种组合。钥匙位于gaff的末端，因此只有一个用户可能会锁定或解锁交换机。
