Definitions
- the invention relates to an electrical switchgear with a series circuit consisting of a first disconnector / earthing switch, a circuit breaker and a second disconnector / earthing switch.
- Such a switchgear is well known. It is also known that each of the three switches, a drive is assigned, with which the respective switch can be switched to its switching positions.
- the two isolator / earthing switches may only be earthed one after the other. This can be achieved, for example, by electronically monitoring the switch positions of the two isolator / earthing switches and, depending on the determined switching positions, influencing the drive for the respective isolator / earthing switch. In this way, thus by means of the monitoring of the switching positions and the corresponding control of the drives of the two isolator / earthing switch a simultaneous changeover of both disconnector / earthing switch can be avoided in the grounded position.
- the object of the invention is to improve the known switchgear.
- a switching drive having a component provided with a first cam track associated with the first disconnector / earthing switch and provided with a second cam track associated with the second disconnector / earthing switch, wherein the component is drivable by a single drive.
- the switching positions of the two isolator / earthing switch can be specified via the two curved paths. With the help of the two curved paths, any change or sequence of switching positions of the two isolator / earthing switches can thus be set in advance in a desired manner. Since the two cam tracks are arranged on or on the same component, only the set switching positions of the two isolator / earthing switch can occur. However, other switching positions or changes in the switching positions can not occur.
- the two isolator / earthing switch can be locked by the invention in terms of their switching positions in a desired manner to each other.
- the cost of this lock is low.

- These three switch positions are referred to below as positions P11, P12, P13 for the first disconnector / earthing switch TE1 and as positions P21, P22, P23 for the second disconnector / earthing switch TE2.
- the two isolator / earthing switches TE1, TE2 are mechanically coupled to a common switching drive 15.
- the mechanical coupling is shown only schematically in FIG. 1 as arrows 16, 17.
- the switching drive 15 of Figure 1 is described below with reference to FIG 2 in more detail.
- the circuit breaker LS is either closed and thus turned on or open and thus causing an interruption. Between the two switch positions of the circuit breaker LS can be switched back and forth with the aid of a in the figure 1 only schematically indicated as arrow 19 means.
- FIG. 2 shows a first embodiment 15 'of the common switching drive 15 for the two isolator / earthing switches TE1, TE2 shown in more detail.

- the switching positions P11, P12, P13, P21, P22, P23 of the two isolator / earthing switches TE1, TE2 are indicated in FIG. 2, in each case with an associated electrical circuit symbol. It should be noted that the circuit diagrams shown are only for the purpose of explanation and need not necessarily be present.
- the switching drive 15 ' has a frame 21, on which an electric motor 22 is held.
- the electric motor 22 has a drive shaft 23 which carries a cam 24.
- the axis of the cam 24 is aligned coaxially with the drive axis 23 of the electric motor 22.
- the cam 24 can thus be rotated by the electric motor 22 about its axis in both directions.

- the first position indicator SA1 indicates which of the three possible switching positions P11, P12, P13 the first disconnector / earthing switch TE1 occupies
- the second position indicator SA2 indicates which of the three possible switching positions P21, P22, P23 the second disconnector / earth Switch TE2 occupies. It should be noted that the aforementioned position indicator SA1, SA2 are present only for the purpose of explanation and must by no means be mandatory.
- the rod 26 is a part of the mechanical coupling 16, via which the switching drive 15 is connected to the first isolator / earthing switch TE1.
- the rod 28 is a component of the mechanical coupling 17, via which the switching drive 15 is connected to the second isolator / earthing switch TE2.
- a translational movement of the respective rod 26, 28 thus leads to a movement and optionally change the switching position of the associated disconnector / earthing switch TE1, TE2.

- the two disconnector / earthing switches TE1, TE2 are in this initial position in the switching position P11, P21, in each case the terminals 11, 12 of the disconnector / earthing switches TE1, TE2 with each other are connected.
- the two isolator / earthing switches TE1, TE2 can be switched by the common switching drive 15 ', for example, as follows.
- a first rotation of the cam 24 in a counterclockwise direction causes both isolator / earthing switches TE1, TE2 to go into their switching position P12, P22. This means that the terminals 11, 12, 13 of the two isolator / earthing switches TE1, TE2 are not connected to each other and the two isolator / earthing switches TE1, TE2 are thus opened, but not earthed.
- both inputs / outputs EA1, EA2 are earthed.
- a rotation of the cam 24 in the opposite direction, ie in a clockwise direction causes the two isolator / earthing switches TE1, TE2 return to their initial position, ie in the switching positions P11, P21.
