Definitions
- the invention relates to a high-voltage outdoor switch with an insulating housing and an interrupter unit arranged in it and with two current transformers arranged on the housing on the other side of the interrupter unit, at least one of which is at high voltage potential during operation of the switch.
- each current transformer on both sides of an interrupter unit makes it possible to calculate the current differences and thus to determine any earth faults in the area of the interrupter unit.
- DE-OS 18 10 405 Also known from DE-OS 18 10 405 is an encapsulation housing at ground potential with a high-voltage switch and current transformers arranged on both sides.
- the present invention is therefore based on the object of providing a structurally simple and cost-effective monitoring of the operability by means of current transformers in a high-voltage outdoor switch.
- the object is achieved in that at least one of the current transformers is arranged in the gas space of the interrupter unit.
- the current transformers can be integrated cost-effectively into the housing of the high-voltage switch and it is not necessary for each of the current transformers to be set up on its own.
- Low-power converters, optical current transformers or surface acoustic wave elements can be used in a particularly favorable form in this way.
- An advantageous embodiment of the invention provides that the high-voltage outdoor switch has the shape of an upright pole column with current transformers arranged above and below the interrupter unit.
- the measurement signals of the current transformer arranged at high voltage potential are advantageously conducted to the ground potential via optical waveguides. This avoids the need to lay an electrical conductor from the high-voltage potential to earth potential.
- an electro-optical converter is provided in the region of the current transformer. This can be done by decoupling energy can be supplied with energy from the magnetic field of the primary current or by means of energy inflow in the form of electromagnetic radiation, in particular by means of an optical waveguide.
- the converter can be arranged both inside and outside the gas space of the interrupter unit.
- the optical waveguide can be integrated into the insulating material housing of the high-voltage switch particularly advantageously.
- the insulating material housing consists of a material into which the optical waveguide can be cast, such as, for. B. fiber reinforced plastic.
- a capacitive voltage converter is integrated in the housing of at least one current transformer.
- a further advantageous embodiment of the invention provides that the housing is at least partially designed as a composite insulator, in particular consisting of a fiber-reinforced plastic.
- FIG. 1 shows schematically in a longitudinal section a high-voltage outdoor switch with two current transformers and one voltage transformer.
- FIG. 2 shows a switch with two current transformers arranged in its housing.
- FIG. 1 shows a high-voltage circuit breaker which has the form of a pole column 1 which is erected vertically on a support frame 2.
- the pole column 1 has two insulating material housing parts 3, 4, the interrupter unit 5 being shown schematically simplified in the upper insulating material housing part 3.
- a switching rod (not shown) for transferring the drive energy from a drive arranged in the support frame 2 to the interrupter unit 5 runs in the lower part 4 of the insulating material.
- connections 6, 7 of the circuit breaker are arranged at the upper end of the upper insulating housing part 3 and between the upper and lower insulating material housing parts 4, and conductors 8, 9 are connected to these connections for connection, for example, each with an overhead line.
- the measurement signals from the current transformers 10, 11 can be transmitted, for example, by radio to earth potential. It could also be provided that instead of the conventional current transformers, optical current transformers are used which are based, for example, on the Faraday effect and whose measurement signals are transmitted via an optical waveguide which is in the housing wall of the insulating material housing 3, 4 or on the outside of the housing long, can be conducted to earth potential.
- the current transformer 10 which is arranged at the upper end of the upper insulating housing part 3, additionally carries a measuring electrode 12 which forms a capacitive voltage divider with the high-voltage conductor 13 and thus permits the capacitive measurement of the high-voltage potential of the high-voltage conductor 13.
- the current transformers 10, 11 can be arranged in separate housings which can be fastened to connecting flanges of the insulating material housings 3, 4.
- the current transformers 14, 15 can also both be arranged coaxially to the insulating material housing 3, so that the need for additional housings is eliminated.
- the converter cores can be attached to the support tube of the interrupter unit.
