Definitions
- the invention relates to a switching device with a movable switching element for producing a isolating section and with a switching element integrated in the switching element.
- Switching devices of this type are known as fuse disconnectors.
- the movable contact pieces contain fuses, the ends of which are provided with knife contacts, as is e.g. utility model G 94 04 155.5 can be found.
- a switching device e.g. a soft starter for three-phase synchronous motors, a load current or circuit breaker to switch to the supply side.
- semiconductor switching elements which e.g. Contain silicon or, in a particularly advantageous manner, silicon carbide as the substrate.
- silicon carbide the excellent insulating properties of silicon carbide when appropriately activated in the blocking state, a visible isolating distance should be provided for safety reasons if the current flow is interrupted.
- the invention is therefore based on the object of improving a switching device of the type mentioned above in such a way that the advantageous properties of semiconductor switching elements are combined in a simple manner with the requirement for a visible isolating path.
- the switching element is a semiconductor switching element.
- FIG. 1 shows a switching device with in a movable
- Switch integrated semiconductor switching elements in the closed state shows a switching device with in a movable
- FIG 3 shows a switching device with semiconductor switching elements and a remote-controlled switch in series with this with a separating element.
- the switching device consists of at least one semiconductor switching element 1, which is integrated in a movable switching piece 2, which is used to produce a separating distance.
- 1 there are two bidirectionally switched semiconductor switching elements 1, the substrate of which is e.g. consists of silicon or silicon carbide, part of the movable contact piece 2.
- the connections of the movable contact piece 2 are advantageously designed as knife contacts, as is known from fuse disconnectors.
- 1 shows the closed state of the switching device, whereas FIG. 2 shows its open state, in which a separating path 4 is visible after opening of the movable switching element 2.
- the switching device can be constructed in one and / or multiphase.
- FIG. 3 shows a further embodiment of the switching device according to the invention, in which the semiconductor switching elements 1 are fixedly arranged and in series there is a remotely operable isolator or switch 3 with which the requirements for a visible isolating path are met can.
- Remote-controlled switches and semiconductor switches can form a device-related unit.
- the semiconductor switching elements can also be operated remotely, for example via a motor.
