Definitions
- the invention relates to a tap changer with vacuum interrupters for uninterrupted
- the invention further relates to a particularly suitable for such a tap changer novel vacuum interrupter.
- a tap changer which has a total of four vacuum interrupters per phase.
- each of the two load branches are each a vacuum interrupter as
- Overload resistor designed as a resistance contact.
- the main contact of the disconnecting side is first opened, then closes the resistor contact the receiving side, so that between the two stages n and n + 1 through the switching resistors limited compensating current flows. After the previously closed resistance contact has opened the disconnecting side, then closes the main contact of the receiving side, so that the entire load current from the new winding tapping n + 1 leads to the load dissipation; the switching is completed.
- Load branch and the load dissipation nor mechanical switching elements are provided.
- the known tap changers require four separate vacuum interrupters per phase.
- the disadvantage is first of all the high space requirement for these vacuum interrupters themselves and the associated actuating mechanism.
- the high component cost due to the high component cost, such known constructions are relatively expensive.
- the object of the invention is to provide a tap changer, which is constructed simpler with the same functionality, in which the switching elements require less space, continue to be cheaper.
- the tap changer according to the invention is based on the general idea, in each case the main contact in a load branch and the resistance contact in the other load branch to a single
- the vacuum interrupter according to the invention is also based on the general idea, by combining a design of a tube with only one movable contact system and two Alternatively, in the manner of a switch, contactable fixed contacts to combine the functionality of two tubes in a tap changer.
- the novel vacuum interrupter tube is simple; In particular, it has no internal contact pressure springs or sliding contacts.
- Particularly advantageous in the case of the vacuum interrupter according to the invention is only a movable contact system, which occupies little space and requires only simple actuation mechanism.
- Vacuum interrupters with two contact points are already known per se.
- DE 3344376 relates to a vacuum interrupter with two electrically connected in series
- DE 197 56 308 C1 relates to a similar vacuum interrupter with two arranged on a common axis switching sections, wherein internal contact pressure springs are provided.
- EP 0 258 614 B1 describes the combination of a vacuum interrupter and a specific circuit on a tap changer. Here, several switching paths are arranged in a vacuum space, which causes a complicated structure of the vacuum interrupter with annular fixed contacts.
- DE 10 2006 033 422 B3 describes a further vacuum interrupter with multiple functionality, in which case also both annular fixed contacts and internal ones
- FIG. 1 shows a tap changer according to the prior art
- Figure 2 shows a switching sequence of such a known tap changer
- FIG 4 shows a tap changer according to the invention with two inventive
- Vacuum interrupters in a schematic representation
- FIG. 5 shows another tap changer according to the invention
- FIG. 1 shows a known tap changer. It has a first load branch, in which acting as a main contact vacuum interrupter MSV a and in parallel thereto
- Overload resistor R a and acting as a resistance contact vacuum interrupter TTV a are.
- the second load branch quite analogously has a vacuum interrupter MSV b and, in parallel with this, another overvoltage resistor R b and a vacuum interrupter TTV b .
- the known tap changer thus has two vacuum switching cells per load branch, thus four vacuum switching cells per phase in total.
- Figure 2 shows the switching sequence of such a known tap changer when switching from the winding tap n to the winding tapping n + 1. The starting position at which the
- Switching elements Switching takes place in the following steps:
- FIG. 3 shows a vacuum interrupter combined according to the invention.
- an upper movable plunger 2 Centrally in the rotationally symmetrical longitudinal axis s1 is an upper movable plunger 2 and at the opposite end a lower fixed contact terminal 3 is provided.
- the movable plunger 2 carries at its inner free end a movable contact piece 4.
- the fixed lower contact terminal 3 in turn carries a fixed contact piece 5.
- Contact piece 4 is a circumferential annular fixed contact arrangement 6 is provided, which is perpendicular to the rotationally symmetrical longitudinal axis s1 in the plane shown here horizontally s2.
- a fixed contact 8 is fixed, which is soldered, for example. This fixed contact 8 is in an end position of the movable plunger 2 of the
- Contact piece 4 can be connected. In the other end position of this contact piece 4 connects the fixed contact piece 5 of the lower contact terminal 3.
- the movable contact piece 4 can thus beschaltten in the manner of a switch either both the fixed contact 8 and the fixed contact piece 5.
- Vacuum interrupters achieves several advantages: the number of necessary vacuum interrupters is de facto halved; correspondingly lower is the space required for these switching elements. The costs are also falling. This is achieved by the vacuum interrupter used in the invention, which is designed as a "tandem tube" namely two separate switching contacts, but contains only a single movable contact system.
- the vacuum interrupter according to the invention is simple; In contrast to the solutions known from the prior art, it requires neither internal contact pressure springs nor complicated operating mechanisms or special filigree contact formations.
- FIG 4 shows a schematic representation of a tap changer with two load branches, as has already been explained in Figure 1 and 2. It can be seen that according to the invention, the vacuum contact tube MSVa of the first load branch acting as the main contact and the vacuum interrupter TTVb of the second load branch acting as a resistance contact of the first load branch in a first invention
- Vacuum interrupter V2 united.
- Contact piece 4 assumes the function of TTVb.
- the contact path between fixed contact piece 5 and movable contact piece 4 assumes the function of MSVb, while the contact distance between fixed contact 8 and movable contact piece 4 takes over the function of TTVa.
- other circuits of the contact sections of the two vacuum interrupters V1, V2 are possible within the scope of the invention.
- FIG. 5 shows a further tap changer according to the invention, in which mechanical switching elements (MDC a , MDC b ) are additionally provided, which serve for galvanic isolation of the load branch not leading to the load current.
- MDC a , MDC b mechanical switching elements
- Vacuum interrupters are each required with only one movable, driven contact piece to replace a total of four separate contacts in the two load branches.
