Definitions
- the invention relates to a monitoring system for tap changers, in which the load switching in each phase to be switched is carried out by means of at least one vacuum interrupter.
- Vacuum interrupters For tap changers where instead of conventional mechanical contacts for load switching Vacuum interrupters can be used in a monitoring and security system Analogy to monitoring mechanical contacts under oil - in many cases it makes sense that ensures that in the event of a fault, if one vacuum interrupter when switching to another Level does not open in time or does not open at all and the tapping change is therefore not without performance an operation becomes impossible. In such a case, a non-opening Vacuum interrupter there is strong arcing on the mechanical contacts, what leads to increased burn-off on these contacts. Frequent switching under an arc This can lead to faults at the tap changer, but in any case to a critical one Operating condition that should be avoided.
- each vacuum interrupter is in the power supply one current transformer each, which has an output voltage for one transmitting diode (LED) of an optical fiber.
- the current transformers report via the respective optical fibers, at the end of which there are light receivers, whether there is a current flow in the respective branch or not. Certain inspection times are provided for this. So at the time of Sequence of movements each time the tap changer is operated, in which the vacuum interrupters are straight have opened, but the inefficient movement of the level selector has not yet started Status of the vacuum interrupter checked. At this point occurs in one of the phases to be switched a current flow indicates a defective - because not open - vacuum interrupter, and a phase-related error message is generated.
- the object of the invention is therefore to overcome the disadvantages of the known monitoring system avoid and to specify such a generic system that a non-contact External vacuum interrupters can be monitored.
- the surface acoustic wave used in this invention (A kustician O bermati w Ellen-) sensors, as a SAW (S urface A Custic W ave) sensors referred to, are known per se. So far, however, no suggestion has been made or no attempt has been made to use them on tap changers in a suitable manner.
- Known AOW sensors usually consist of a LiNbO 3 substrate, which is arranged in a metal or ceramic housing, as is used for integrated circuits. Such a sensor can be read wirelessly via radio; the propagation losses to the AOW sensor are extremely low and the sensor does not require any energy supply for signal processing. In addition to the actual AOW sensor located at the measurement location, a query unit is required for radio polling.
- High-frequency pulses in the frequency range between 100 MHz and 3 GHz are emitted by an oscillator of this interrogation unit via an antenna.
- On the AOW sensor itself there is an interdigital transducer connected to an antenna and in many cases several reflectors.
- the interdigital transducer usually in the form of a comb, is excited by the received high-frequency electromagnetic pulse, and an acoustic surface wave is generated via the piezoelectric effect. This surface wave is partially reflected at the reflectors, so that it reaches the interdigital transducer again. There it is converted back and emitted via the antenna of the AOW sensor and can be received by the interrogation unit.
- the pulse sequence emitted by the AOW sensor which is received by the interrogation unit, initially contains, as information, a specific, specific bit pattern of the sensor which is used to identify it.
- a single interrogation unit can therefore receive the information from a large number of different AOW sensors and assign it to the individual sensors.
- a change in a relevant physical quantity on the sensor leads to a change in the speed of the described surface wave propagating on the sensor or also to a change in the geometric spacing of the reflectors. This results in a change in the pulse duration, which is recorded and evaluated in the interrogation device and which allows conclusions to be drawn about the corresponding physical variable or its change in the environment of the respective AOW sensor.
- Such an AOW sensor is described in detail in WO 96/33423 from SIEMENS AG.
- Such AOW sensor is also already known from WO 96/33417 by the same applicant for current measurement on electrical devices connected to high voltage use.
- this type of current transformer application there is a magneto-sensitive element provided that is coupled to the surface wave structures.
- One known per se Arrangement can be particularly advantageous for a monitoring device according to the invention be used.
- the figure shows the schematic structure of a monitoring device according to the invention.
- the upper area indicates the oil tank 1 of a tap changer in which there are three Vacuum interrupters V1 ... V3 are located - for each phase U, V, W there is one in this example Vacuum interrupter provided.
- the invention is not limited to such an arrangement; the monitoring device according to the invention is suitable for any electrical circuit of tap changers with any number of such vacuum interrupters per phase. It should the status of the vacuum interrupters V1 ... V3 is checked at certain times, d. H. determine whether they are actually open. If this is not the case in the event of an error, flows in the corresponding branch a stream.
- an AOW sensor S1 ... S3 provided outside of the oil tank 1 of the Step switch.
- an interrogation unit 2 which has an oscillator and an antenna.
- the oscillator emits high-frequency pulses via the antenna to the AOW sensors S1 ... S3.
- There they generate a surface acoustic wave in a manner known per se which, after they has been reflected by the reflectors within the respective sensor, emitted back again and is received by the interrogation unit 2.
- the one sent by the query unit 2 high-frequency radiation is indicated by a dashed line.
- S3 radiation transmitted back is represented by dotted lines; the different Puncturing is intended to indicate the specific bit pattern that query unit 2 has Sensor-specific assignment allowed.
- This changed pulse transit time of the signal emitted by the corresponding sensor is from the Interrogation unit 2 is recorded, assigned to the respective sensor as error information and as information given to the monitoring unit 3 known from the prior art.
- the interrogation unit 2 and the monitoring unit 3 can rather be outside the tap changer 1, for example, in the area of the motor drive or elsewhere.
