Definitions
- Switching arrangement for diverter switches of tap changers and for load selectors
- the invention relates to a switching arrangement for diverter switch and for load selector according to the preamble of the first claim.
- Such a switching arrangement is known from DE-OS 25 20 670.
- This known switchover arrangement has two switch contacts which can be moved in two directions and switch load transfer from one to the other step contact, one of which serves as a main switch contact and the other as a resistance switch contact, both being present at the same step contact in the stationary state.
- the movable switch contacts are rigidly coupled to one another and arranged on a common contact carrier and are also actuated together by the movement of the common contact carrier. Depending on the switching direction, one of the contacts alternates, ur. : ' the other follows.
- Each of the movable switch contacts is connected in series to a mechanical series contact, the two series contacts being connectable to the load conductor both simultaneously and individually. This optional connection is made by a movable mechanical isolating or changeover contact.
- an energy storage drive which, when triggered, both moves the two movable, mechanically coupled switching contacts and actuates the isolating contact.
- Vacuum interrupters which are particularly advantageous because of their absence of erosion and the resulting avoidance of contamination of the medium surrounding them, and because of the high number of switching cycles that can be achieved
- both switch contacts must be actuated jointly by the energy accumulator.
- the energy isolator must also have the mechanical isolating contact which connects the respective connection to the energy accumulator Manufactures load transfer, be operated with, so that overall there is a complicated kinematics and a necessarily mechanically complex energy storage.
- the invention has for its object to provide a switching arrangement of the type mentioned, which is applicable both for load switch and load selector, which allows the use of vacuum interrupters in the main as well as in the resistance branch and which has simple kinematic conditions and thus only an uncomplicated , has the same type of force in both release directions and only realizes the same switching step to actuate the actuation as few switching means as possible.
- a particular advantage of the switchover arrangement according to the invention is that it achieves the lowest possible switching power stress. This makes it possible to provide as a safety device against the possible and statistically unpredictable failure of a vacuum interrupter, a mechanical series emergency switching route, which is also present when using the switchover arrangement according to the invention for a load selector anyway and which is particularly easy to use by a known optoelectronic Arc detection with circuit breaker tripping can be monitored in the event of a response.
- the switching arrangement according to the invention can be constructed with smaller and correspondingly inexpensive vacuum interrupters.
- Another particular advantage of the switchover arrangement according to the invention is that the separate actuation of the main switch contact on the one hand and the resistance switch contact on the other hand provides a large switching path, which is important with regard to the spacing of the contact elements and thus the achievable dielectric strength and also with regard to the reconsolidation voltage when the emergency switching path is used is.
- Fig. 1 shows a first switching arrangement according to the invention as part of a
- FIG. 4 shows the associated circuit diagram for a multi-stage tap changer for this first switching arrangement.
- Fig. 5 shows a second switching arrangement according to the invention as part of a
- Fig. 7 shows a third switching arrangement according to the invention as part of a
- the switching sequences of the first switching arrangement according to the invention are basically the same regardless of whether this switching arrangement acts as part of a load changeover switch or as part of a load selector.
- the load selector has multiple circuits in the same switching direction, i.e. e.g. from n via n + 1 to n + 2, are possible, while this is also the case electrically with the diverter switch, but mechanically switched between only two positions with each switching, i.e. the switching direction is changed.
- the switching arrangement shown in FIG. 1 has fixed step contacts, A, B, which are connected in a known manner via a step selector to taps n, n + 1, n + 2, ... of the step winding.
- the actual switching arrangement switches between these fixed step contacts A, B.
- This consists of a main switching contact SKM, which is connected to the common lead via a first vacuum switching cell SKV, and a resistance switching contact HKM, which can be moved independently of it and without mechanical coupling, and which also connects to the common one via a series connection of a second vacuum switching cell HKV and an override resistor R. Derivative is connected.
- permanent main contacts DHK ⁇ , DHKß are advantageously provided in this embodiment, which carry the load current in stationary operation and thus relieve the switching arrangement.
- Fig. 2 shows this first switching arrangement as part of a load selector, here too the permanent main contacts are not absolutely necessary; The differences in the actuation of the changeover arrangement as part of a load switch on the one hand and a load selector on the other hand have already been pointed out.
- Switching step 1 basic position; DHK ⁇ carries the load current switching step 2: DHKA has opened, the main switching contact SKM and the first one
- SKV vacuum interrupters have taken over the load current Switching step 3: The first SKV vacuum interrupter has opened, the load current flows through the HKM resistance switching contact, the second
- Vacuum interrupter HKV and the switching resistor R Switching step 4 The main switching contact SKM leaves one after tripping
- the energy accumulator quickly reaches the fixed step contact n or A switching step 5: the main switching contact SKM has reached the new fixed step contact n + 1 or B switching step 6: the first vacuum switching cell SKV closes and switches the load current to the fixed step contact n + 1 or B; about the still closed second vacuum switch HKV and the switching resistor R only the compensating current flows
- Compensating current switching step 8 The resistance switch contact HKM leaves the fixed step contact n or A and follows the main switch contact SKM in the movement to the new fixed step contact n + 1 or B.
- Switching step 9 The HKM resistance contact has reached the new fixed step contact n + 1 or B.
- Switching step 10 The second vacuum switch HKV closes switching step 11: The permanent main contact DHKß closes and takes over the load current; the output control is reached again, and the switching arrangement is ready for a new switching.
- FIG. 4 shows the associated circuit diagram for this first switchover arrangement for a multiple step switch from n to n + 1, then to n + 2 and then back to n + 1 for a switchover arrangement according to FIG. 2.
- This circuit diagram is also good for the ones in FIG. 1 illustrated arrangement, in which, as explained above, however, only a mechanical change is made between the two fixed step contacts A and B.
- the main switching contact SKM and the resistance switching contact HKM each consist of two individual interruption contacts SKMA, SK-Mß or HKM-, HKMg, which can be actuated coupled to one another, wherein each individual interruption contact SKMA, HKMß is electrically connected to the first fixed step contact A and the respective other individual break contact SKMjj, HKMß is electrically connected to the other fixed step contact B.
- Fig. 6 shows the associated switching process. It can be seen that the corresponding permanently existing connections for load dissipation are only closed or interrupted by the respective individual interruption contacts.
- FIG. 7 shows a third embodiment of a switching arrangement according to the invention.
- This type of configuration is also specially designed for diverter switches, which in turn only switch between two fixed step contacts A and B.
- the single break contacts SKM ⁇ , SKMß of the main switch contact SKM described above as well as the single break contacts HKM ⁇ , HKMß of the resistance switch contact HKM are connected by two changeover switches SI and S2.
- the first changeover switch SI optionally closes the single break contact SKM ⁇ or the single break contact SKMjj. This means that there is a double break through four single break contacts, which can be connected in a particularly simple manner with only two changeover switches SI, S2.
- Fig. 8 shows the associated switching process from the fixed step contact A to the fixed step contact B and back again. It can be seen that in this embodiment, too, the main switch contact reaches the new fixed step contact B, ie connects it directly to the load conductor L before the resistance switch contact contacts the previous fixed step contact A leaves, ie its previous connection via the
- Resistor switch contact takes place without mechanical coupling.
