Definitions
- the invention is based on a current-limiting switch the preamble of claim 1.
- Such current-limiting switches can be in the high or medium voltage range as a generator switch, as a tie switch between busbar sections in Switchgear, as a DC switch or in meshed networks for reduction of operating losses are used.
- the invention takes on a prior art of current limiting switches reference, as in the as yet unpublished European application EP Registration no. 98811251.2.
- This switch has a quick mechanical switching point with galvanic contacts and two in parallel switched commutation paths.
- the first commutation path are in series a first switching device and an isolating switching point arranged in the second Commutation path are a current limiter and a second switching device in Series switched.
- the current limiter is designed such that it is guided Current, which when opening the first switching device from the first to the second Commutation path is commutated, is limited with a time delay. During this There can be no time delay over the two commutation paths Build up overvoltage and can also be in the first commutation path overvoltage-proof isolating path are formed.
- the object of the invention is as set out in the claims based on a current-limiting switch of the type mentioned create, which thanks to its special, space-saving structure and the small moving mass because of a quick switching on and off in the up and Medium voltage range enabled.
- the current-limiting switch according to the invention has three in parallel to each other arranged paths, two of which contain a mechanical switching point.
- One of these mechanical switching points is for guiding and switching Rated current, while the other is only briefly and when switching through which a commutated current flows.
- the Contact arrangements of the mechanical switching points are axially symmetrical trained and arranged coaxially. Thanks to short, coaxial copper connections there are very small leakage inductances, which results in a very fast Commutation of the currents is made possible.
- the third path of the switch according to the invention also contains a mechanical one Switching point with a coaxially arranged contact arrangement, is unnecessary conventional current-limiting switches in series-connected series isolators.
- This can reduce the dimensions of a housing, in which the contact arrangements are arranged, for example against dust or to be protected from other disruptive influences.
- The is particularly advantageous Arrangement of the contact arrangements in a pressure-resistant housing, which for example with an insulating gas under atmospheric or higher pressure is filled, which is beneficial to the dielectric property of the contact arrangement affects. If the housing contains two electrically conductive, isolated parts, the nominal current can be connected directly to the connections of the Lead nominal current switching point. Elaborate nominal current feedthroughs through the Housing is thus eliminated.
- the circuit shown in Fig. 1 is a single-phase basic circuit of a test device emulating a medium-voltage network with a first embodiment of a current-limiting switch S according to the invention.
- the test device contains a generator Q simulating a mains voltage U N of a few 10 kV, the switch S and a load L simulated from an ohmic resistor R L and an inductor L L.
- a short-circuit current detection unit E is connected between the generator Q and the switch S, which contains a measuring and evaluation part for the very rapid detection of short-circuit currents of up to some 10 kA.
- the switch S has a nominal current switching point S 1 located in the current path from the generator Q to the load L. Two commutation paths P 1 and P 2 are connected in parallel with the nominal current switching point S 1 .
- the first commutation path P 1 contains an isolating switching point S T and a power electronic switching device T with a diode bridge D 1 , D 2 , power semiconductors H that can be switched off, for example GTO, and a surge arrester M.
- the diode bridge allows switching of alternating currents both with positive and with negative Polarity without power semiconductors connected in anti-parallel.
- the second commutation path P 2 connected in series, contains a switch-off switching point S A and a current limiter R B , which responds to a current with a time delay and is designed, for example, as a PTC resistor.
- the switch-off switching point can be designed as a semiconductor switch H A with antiparallel switched, switchable power semiconductors, for example GTOs, or comprise a galvanically isolating mechanical contact arrangement K A , preferably a vacuum switch.
- the switching points S 1 and S T of the switch according to FIG. 1 each have a contact arrangement K 1 and K T that opens very quickly, within a few 100 ⁇ s.
- the contact arrangement K 1 of the nominal current switching point S 1 is arc-proof.
- the two contact arrangements K 1 and K T of the switching points S 1 and S T are arranged in a housing G.
- the two contact arrangements K 1 and K T of the switching points S 1 and S T are connected via a connection 1, a first housing part 10 and primary leads 11 and 12.
- the nominal current switching point S 1 is connected to the connection 2 via a secondary feed line 21 and a second housing part 20.
- the isolating switching point ST of the first commutation path P 1 is connected to the power electronic switching device T via a secondary feed line 31 which is guided through the housing G with a bushing 5 and via a connection 3.
- the contact arrangements K 1 and K T of the two switching points S 1 and S T and the switch-off switching point S A are closed or conductive. If a short-circuit current occurs, the detection unit E triggers a switch-off process at the current-limiting switch S within approximately 100 ⁇ s. The semiconductor elements H lying in the first commutation path P 1 are immediately made conductive. At the same time, the contact arrangement K 1 of the nominal current switching point S 1 is opened. Due to two arcs formed in series, the short-circuit current that is still rising commutates into the first commutation path P 1 within approximately 150 microseconds.
- Fig. 2 shows a possible arrangement of the first embodiment of the switch according to the invention.
- the two switching points S 1 and S T are mostly arranged coaxially symmetrically in a cylindrical housing G.
- the housing G is composed of two plate-shaped, electrically conductive housing parts 10 and 20, a tubular, electrically insulating housing part 7 and two electrically insulating, gas-tight bushings 5 and 6.
- the housing G is designed to be pressure-resistant and filled with a gaseous medium, for example air or SF 6 under atmospheric or higher pressure.
- the two contact arrangements K 1 and K T are arranged one inside the other, the contact arrangement K 1 of the nominal current switching point S 1 , since it requires a corresponding cross section for carrying nominal current, has the largest diameter and is arranged on the outside.
- the contact arrangement K T of the isolating switching point S T through which a commutating current flows only briefly and in a pulse-like manner only when switching, has a correspondingly smaller diameter and is arranged coaxially within the contact arrangement K 1 of the nominal current switching point S 1 . 2, the leads to the contact points are as short and axially symmetrical as possible.
- the arrangement of the second embodiment of the switch according to the invention shown in FIG. 4 largely corresponds to the arrangement of FIG. 2.
- the switch-off switching point S A is arranged coaxially symmetrically in the housing G.
- An advantageous embodiment of the drive of a switching point looks next to one movable bridge contact piece, which is part of the contact arrangement of the switching point is essentially two coils and a power electronic control unit.
- the contact arrangement and the coils are axially symmetrical and arranged coaxially to each other.
- the exact structure of the three switching points will with reference to a section of the arrangement shown in FIG. 2 shown in FIG explained.
- the Contact ring is acted upon by electrodynamic force from the Power electronic control unit fed into the corresponding coil of energy becomes.
- the contact ring can be in the axial direction between the two coils 81 and 82 are moved back and forth while opening the contact arrangement and again conclude.
- the contact ring 85 fitted between the two fixed switching pieces 84 and closes them short.
- the contact ring 85 In the open position of the contact arrangement, the contact ring 85 of held a holding part 83.
