Definitions
- the invention relates to a switch for a transmission link of the high voltage direct current transmission.
- High-voltage DC transmission in particular for the construction of HVDC multi-terminal and HVDC power systems, requires circuit breakers. These circuit breakers must be able to safely switch off both the rated currents and short-circuit currents. Current rated voltages are 550 kV. In the future, the nominal voltages can reach 800 kV or even 1000 kV. The nominal currents are about 2 to 5 kA. The short-circuit currents to be disconnected can amount to a multiple of the rated current. A circuit breaker for high-voltage direct current electrical isolation must also ensure stel ⁇ len.
- Existing HVDC systems are designed as point-to-point solutions. Shutdowns of these systems are made by a regulation of the respective converter stations.
- the switch according to the invention for a transmission line for high-voltage direct current has a series circuit of a first and a second switching device, wherein the first switching device is configured for power interruption and the second switching device is designed forpalsisola ⁇ tion.
- the switch includes a Device for establishing a countercurrent against the current in the transmission path to lower the current through the switching devices.
- the first switching device preferably has a vacuum circuit breaker.
- Switching device preferably has a gas-insulated, oil-insulated or low-oil circuit breaker.
- the device for setting up a counter voltage preferably has a high-voltage capacitor and a switch. It is advantageous if the elements are connected in parallel to the vacuum Leis ⁇ tung switch. In normal operation, the high-voltage capacitor is charged, but electrically decoupled by the switch at least on one side. If a current ⁇ lowering to happen, the switch is closed.
- Switch may be a semiconductor switch such as a thyristor may be used or a second gas-insulated circuit breaker.
- a third switching device for example, a thyristor or another gas-insulated circuit breaker can be used.
- the switch has a device for limiting the current increase in series connection to the first switching device.
- This can, for example, an inductance in series with a parallel circuit of a non-linear In productivity and capacity.
- cost- and energy-intensive superconducting solutions always need a fail-safe cryogenic omitted.
- the switch expediently comprises a control device. This is preferably designed to determine the temporal change of the current and to determine therefrom the presence of a short ⁇ circuit, and output in the presence of a short circuit control signals so that the first switching device is opened.
- the controller is further preferably configured to control the means for establishing a counter ⁇ stream in the presence of a short circuit to establish a counter flow and to control the vacuum circuit breaker, with the lowest possible amount of current insbeson ⁇ particular to switch off at a zero crossing of the current thereof.
- control device adjusts the magnitude of the countervoltage on the basis of the measured change in the current. As a result, a fast and safe shutdown is achieved by the vacuum circuit breaker.
- Figure 1 shows a schematic structure of a switch for a
- Figure 2 shows a structure for a Strom Sungsbe dictionary and Figure 3 shows a structure for a device for generating a high-voltage DC transmission link
- Figure 1 shows schematically the structure for an embodiment ⁇ example of a switch.
- the switch is in one
- High-voltage DC transmission line 1 is arranged and can be connected via terminals 2 with other lines.
- the switch comprises a vacuum circuit breaker 3.
- the vacuum circuit breaker 3 is realized in a known manner.
- the switch comprises a device 4 for generating a countercurrent.
- a sol ⁇ che device 4 for generating a countercurrent is shown in Figure 3.
- the device 4 for generating a countercurrent comprises in series a Hochwoodskon ⁇ capacitor 21 and a thyristor 22.
- the thyristor 22 can here also another semiconductor switch, such as an IGBT, are used.
- the switch further comprises a current change limiter 6.
- An exemplary structure for the current change limiter 6 is shown in FIG.
- the Strom Sungsbeskyr 6 in this case comprises a parallel connection of a non-linear inductance 12 and a capacitor 13. This parallel circuit is in turn ⁇ connected in series to a further Indukti ⁇ tivity. 11
- the switch comprises a gas-insulated circuit breaker 5, for example a SF ö switch.
- the gas-insulated circuit breaker 5, the vacuum circuit breaker 3 and current change limiter 6 are connected in series. Parallel to the vacuum circuit breaker 3, the device 4 is arranged to generate a counterflow.
- a control device 7 is connected to the aforementioned elements.
- the control device 7 receives a measurement signal for the current change dl / dt.
- Another STEU ⁇ ertagen exists between the controller 7 and the vacuum circuit breaker 3, and the control means 7 and the means 4 for generating a counter-current.
- the control device 7 monitors the measured values for the temporal change of the current. In the case of a short circuit , the flowing current would rise sharply. The Strom Sungsbeskyr 6 prevents this strong increase for the time being.
- the control device 7 detects the still increasing current, the presence of a short circuit. As a result, he ⁇ demonstrates the controller 7 switching commands for the other elements of the switch. These control commands consist in an opening of the vacuum circuit breaker 3, the gas-insulated circuit breaker 5 and in turning on the thyristor 22 in the device 4 for generating a counterflow. In this case, the control device 7 determines the chronological sequence of these commands. Appropriately, a countercurrent is generated quickly. In this case, the generation of the countercurrent is controlled so that ideally passes a current zero crossing. At the
