Definitions

  • the invention relates to a multi-position commutation isolator for high and medium voltage switchgear according to the preamble of claim 1.
  • Such a multi-position commutation isolator for high and medium voltage switchgear is known from DE-OS 35 06 383.
  • the multi-position commutation isolator described there is used for the uninterrupted changeover of feed lines or cable outlets to the main and auxiliary busbar.
  • the feed lines or cable outlets are galvanically connected to the main busbar.
  • the feed lines or cable outlets are connected to both the main and the auxiliary busbar, which is done by means of a sliding contact arrangement.
  • the feed lines or cable outlets are galvanically connected to the auxiliary busbar.
  • the feed lines or cable outlets are separate from the main and auxiliary busbars.
  • DE-OS 34 12 399 discloses a high-voltage device designed as a three-position switch (operating position, disconnected position, earthing position) which is suitable as a load break switch and earthing switch.
  • the three-position switch is designed with a switching arm that can be swiveled around a fixed point.
  • a switching element preferably a vacuum interrupter, is arranged in series with the separating distances in the insulating medium that arise in the middle position. The uninterrupted commutation of a current is not possible with this switching device.
  • Disconnectors are generally switchgear in electrical power distribution systems. They normally switch off almost without current. When switched on, isolators must be able to carry operating and short-circuit currents.
  • Disconnectors with the task of uninterrupted commutation of currents are known for example from EP 0 126 882. There, however, two separate isolators are required for commutation.
  • a multi-position commutation isolator of the type mentioned in the introduction has become known from US Pat. No. 4,016,385.
  • the contact device is formed by a plurality of vacuum tubes, so that in each case one vacuum tube is assigned to the individual contact devices.
  • the control of the vacuum tubes is carried out by control disks with slots made therein that two vacuum tubes assigned to each other are closed simultaneously, whereby the closing time of both pairs of vacuum tubes overlaps for a certain time.
  • the object of the invention is to simplify a multi-position commutation isolator of the type mentioned at the outset without the effectiveness of the multi-position commutation isolator being impaired.
  • the separation, connection and commutation functions of the multi-position commutation isolator can be carried out by a single mechanical drive. Only one single multi-position commutation isolator is required per infeed or outgoing line of a switchgear with a main busbar and two or more auxiliary busbars.
  • the multi-position commutation isolator thus enables the construction of a switchgear that is significantly cheaper than conventional switchgear with minimal circuit breaker effort.
  • the multi-position commutation isolator 1 with drive 2 has four external connections 3, 4, 5 and 6.
  • the external connections 3 or 5 or 6 are connected directly to internal contacts 7 (main current path contact) or 8 or 9 (secondary straw path contacts).
  • the isolator 1 has two earth contacts 10 and 11, respectively.
  • the external connection 4 is connected internally to a contact pin 12 movable by the drive 2.
  • the contact pin 12 is provided at its freely movable end with a sliding contact 13 (movable contact device) for optional connection to the contacts 7 to 9 or earth contacts 10, 11.
  • connection 3 to connection 4 The internal electrical connection from connection 3 to connection 4 is referred to as the main current path and the connections from connection 4 to connection 5 and from connection 4 to connection 6 are referred to as the secondary current path.
  • the switching position shown in Figure 1 of the movable contact pin 12 and the sliding contact 13 attached thereto is just such that the main current path 3-4 is closed.
  • FIGS. 2 to 5 show commutation from the main current path 3-4 to the secondary current path 4-5 and then the separation and the subsequent grounding via the ground contact 10.
  • FIGS. 2 and 3 show two phases of uninterrupted commutation from the main current path 3-4 to the secondary current path 4-5.
  • the sliding contact 13 connects the contact 7 of the main current path 3-4 to the contact 8 of the secondary current path 4-5. Uninterrupted commutation can take place in this phase.
  • the end of commutation is shown in Figure 3.
  • the connection between the sliding contact 13 and the contact 7 of the main current path 3-4 is interrupted, so that the current flow now takes place exclusively via the contact 8 of the secondary current path 4-5.
  • FIG. 4 shows a disconnected position in which both the main current path 3-4 and the secondary current path 4-5 and 4-6 are interrupted, and the contact 7 of the main current path 3-4 and the contacts 8 and 9 of the secondary current paths 4-5 and 4 -6 are electrically isolated from each other.
  • commutation can take place from the main current path 3-4 to the secondary current path 4-6, and this can also be followed directly by the separation and grounding via the ground contact 11 connect.
  • FIG. 1 An exemplary embodiment of a multi-position commutation isolator 32 is shown in FIG.
  • the isolator 32 has three contacts 33 (secondary flow path contact), 34 (Main current path contact), 35 (secondary current path contact) and a central commutation sliding contact 36.
  • the commutation sliding contact 36 (movable contact device) has three adjacent contact segments 37, 38, 39, which are electrically insulated from one another by means of insulating pieces 40, 41, the contact segments 37, 38 being arranged at the outer ends of the commutating sliding contact 36 and the contact segment 39 is located in the middle between the segments 37, 38 or between the insulating pieces 41, 40.
  • the commutation sliding contact 36 is attached to the movable end of a pivot arm 42 which can be pivoted about a pivot point 43.
  • the rotary arm 42 is mechanically fixedly connected to an electrically insulating cam 44, which can also be pivoted about the same pivot point 43.
  • the movable contact 47 of a (single) vacuum interrupter 46 see, for example, Burkhard, switching devices of electrical engineering, VDE publishing house, Berlin, Offenbach, 1985, pages 110 to 11), d. H. the vacuum interrupter 46 can be switched on and off via the movable contact 47 depending on the current position of the cam 44.
  • the switching capacity of the vacuum interrupter is adapted to the commutation voltage (inductive voltage due to the coupling between the phases).
  • the two outer contact segments 37, 38 of the commutation sliding contact 36 are electrically connected to one another by a bracket 45.
  • the bracket 45 is connected via a flexible connecting line 49 to the movable contact 47 of the vacuum interrupter 46.
  • the middle (inner) contact segment 39 of the commutation sliding contact 36 is electrically connected to a terminal 52 via the rotary arm 42 and a flexible connecting line 50.
  • the fixed contact 48 of the vacuum interrupter 46 is also electrically connected to the terminal 52 via a flexible connecting line 51.
  • the drive which pivots the rotary arm 42 and the cam plate 44 about the pivot point 43 is designated by the number 53.
  • connection 52 is connected to a feed or outgoing line, the contact 34 to a main busbar, the contact 33 to a first auxiliary busbar and the contact 35 to a second auxiliary busbar.
  • the internal connection from contact 34 to connection 52 is referred to as the main current path and the connection from contact 33 to connection 52 and from contact 35 to connection 52 is referred to as the secondary current path.
  • the contact of the contact segment 39 with the contact 34 is initially maintained.
  • the vacuum interrupter 46 is closed immediately after contact of the contact 33 with the contact segment 37, in that the movable contact 47 of the vacuum interrupter 46 is pressed into the "on" position (downward) by a trapezoidal cam of the cam 44 .
  • the contact segment 39 touches in this switch position still the contact 34, ie the electrical connection 34-39-42-50-52 remains.
  • the multi-position commutation isolator 32 can be provided with further contacts in order to additionally enable grounding.
