Definitions
- the invention relates to a switch control system.
- Electrical power distribution is based on the switching of currents. Typically, a differentiation is high, with ⁇ medium and low voltage. The higher the voltage, the more expensive the switchgear.
- Fig. 1 elements are diagrammatically a high-voltage switchgear ⁇ for switching a power switch ge ⁇ shows.
- Circuit breakers close and open current paths (1) of high electrical voltages and control the switching of operating and fault currents.
- a large vomit ⁇ cherten mechanical energy for example, is provided by a Federspei ⁇ cherantrieb (2) are available, must also be met ⁇ wider conditions for safe operation.
- sufficient extinguishing and insulating gas must be available for a successful switching operation.
- the switching position of the circuit breaker, the status of its on ⁇ drive and its spring accumulator and the pressure of the extinguishing and insulating gas are permanently monitored by electrical switching contacts (3).
- a local electrical or electronic ⁇ specific controller (4) for this purpose interprets the switching states of the contacts and affects a function of the power switch status ⁇ and their wiring or programming the switch functions. Thus, the controller releases switching operations, blocks switching operations or triggers switching operations ei ⁇ genstieri.
- EMC electromagnetic compatibility
- the source of these disturbances are the electromagnetic emissions typical of the circuit breaker, which are set actions of the high voltage switch or thereby foige ⁇ called rapid changes in the voltage and the current.
- EMC electromagnetic compatibility
- noise levels at the terminals of the control components are measurable and may not exceed standards by defi ⁇ ned limits.
- the disturbances can also be measured and can influence the function of the controller and even lead to the destruction of the semiconductors installed in the controller.
- the invention has for its object to reduce the influence of EMC interference on the switch control of switchgear. This object is achieved by a switch control system according to claim 1. Advantageous developments are specified in the subclaims.
- a novel switch control system for controlling a switching device is proposed.
- the switch control system is provided with a controller for control or adjustment formed by settings of the switching device. This may in particular be a local electronic control.
- the switch control system comprises a device for detecting (hereinafter also referred to as "detection apparatus"), one for controlling the switching device re ⁇ -relevant information.
- This detection apparatus detects, for example, status information (for example, manual or motor positions) or a physical parameter (such as pressure, gas own ⁇ shaft, etc.). however, with the information, it may also be a complex information, for example, indicates a fault, the detek- by a plurality of parameter information is advantage.
- the detection device is formed with a diaphragm or a filter case is. not to interpret the word "or” as exclusive.
- the detection device can, for example, both a diaphragm and a filter or be ⁇ undesirables combination of elements "Aperture” and "filtering" umfas ⁇ sen.
- a light path (typically reali means of an interrupted in the area of the aperture or of the optical fiber filter ⁇ Siert) is guided by the controller to the panel and from there back to the controller.
- MEH ⁇ reren possibly separately arranged components are made (for example, a Sen ⁇ dekomponente and a receiving component) such that the light path is not necessarily completed at the same Comp ⁇ component from which it takes its output.
- a separate dedicated component for Erzeu ⁇ supply and supply of light This component would then be conceptualized as part of the controller.
- the invention Weger horrinsky ⁇ system still includes a device for movement of the diaphragm or the filter for influencing (eg in the form of a (complete or partial) interruption or release) of
- a light path in accordance with the information relevant to the control of Wegvor ⁇ direction.
- a light path is influenced in accordance with a relevant for the Steue ⁇ tion of the switching device information.
- the controller preferably for evaluating characteristics (light intensity, the color spectrum of the light in question properties, ...) received from one or meh ⁇ eral light paths of light signals (under light signal is also the lack of the transmission of light at separate mode ⁇ ger interruption of the light path subsumed) and Abbil ⁇ dung or interpretation (eg by table or Abbil ⁇ making rules which are recorded by means of software) the evaluated properties related to. for the control of
- the switch control system for influencing a plurality of guided by the controller to the panel and from there back to the control light paths in accordance with the relevant information for the control of the switching device information ⁇ staltet.
- Be present may for example, also light paths and a Beeinf- lussungen of the light paths in the sense of a redundant supply ⁇ position a rele for controlling the switching device ⁇ -relevant information for the control is provided (the Re can thereby dancy ⁇ implemented both by means of partially redundant, or completely separate light paths be) .
- the circuit control system for a division of a light path by means of a prism or a mirror in be configured a plurality of light paths and an influence of the multiple light ⁇ paths.
- the control for the evaluation is influenced a through the color filter Farban ⁇ partly formed of transmitted via the light path to the controller light. This way you can do more for the
- Control of the switching device relevant information to be transported via a light path This allows opti mized ⁇ means of light paths, for example in the sense of a mög ⁇ lichst low entire light guide route.
- a light path through a plurality of influencing ⁇ forward influenced to ⁇ minimum (where under the control means is a diaphragm or a filter is understood, there is an be ⁇ undesirables combination of similar or different types of influencing means conceivable).
- the plurality may be assigned by the influencing means a single Vorrich ⁇ processing for detecting a relevant for the control of Heidelbergvorrich ⁇ processing information in a first case.
- the invention also includes a switching device and switchgear with an inventive switch control ⁇ system.
- the invention is described below with reference to figures closer ⁇ be enrolled. Show it:
- FIG. 3 is a pressure monitor as an example of a device for detecting a rele ⁇ vanten information for the control of the switching device
- Fig. 5 a further embodiment of a circuit breaker with inventive control system.
- Demie the controller flows through a light source (7), the transmitting optical waveguide (8) with light.
- the opposite sides of these optical waveguides are guided on diaphragms (9), which have the task of those used in conventional solutions
- Switching contacts for circuit breaker status representation over ⁇ take.
- the panels with indicator components in ⁇ example with the interrupter unit (10), the (motor) limit switches (11) or the pressure switch (12), - similar to conventional solutions, the switch contacts - mechanically connected and thus form devices for Detection of a relevant for the control of the switching device In ⁇ formation.
- the circuit breaker status changes one or more stops are moved. As a result, they interrupt the light path or light path to the receiving optical waveguide (13) or release it.
- the pressure of a gas chamber (20) is monitored with the pressure switch (12) ⁇ by the gas pressure in the gas chamber (20) comprises a piston (12a) against a spring (12b) shifts.
- the piston is mechanically connected to the diaphragm (9) and moves it when changing the gas pressure.
- the opaque part of the diaphragm (9a) or the translucent part of the diaphragm (9b) in the cone of light of the optical waveguide (6) As a result, the incidence of light at the receiving unit (19) indicates the exceeding or falling below a limit value of the pressure in the gas space.
- the aperture can be extended to color filter. The gas pressure can then be determined using the light ⁇ color on the receiver.
- the beginning of the recie ⁇ ing optical waveguide (13) is located on the diaphragm opposite side and its end is guided in the receiving unit of the controller.
- the transillumination state of each optical fiber is checked.
- the status information is displayed transmit the control.
- the controller can now release, block or run using the transmitted optical waveguide-information switch handle ⁇ ments.
- the light in the transmitted light path can be split for example by prisms or mirrors (14) and are guided to a plurality of Blen ⁇ addition to the use of several light sources. Redundancies can be realized by the parallel guidance (15) of transmitting and receiving optical waveguides.
- Control-independent interlocks can be imaged by the series connection (16) of several apertures. At least two conditions must be met in order for light to arrive at the receiver.
- the query parameter is therefore "hardware-sided" realized, that is the evaluation of the fulfillment of both condition occurs not in control and can DES half also not affected by error in the control ⁇ to.
- the number of optical fibers used can be reduced by feeding the transmitting optical waveguide (17) with white light whose spectrum contains all the colors. Instead of the apertures which interrupt or connect the light path, color filters (18) are used.
- the lightwave ⁇ conductor (17) is successively ge over all color filters leads ⁇ who change the spectrum of the light according to the switch status. The spectrum, so the color of the incoming light analy ⁇ Siert and thus the status of the circuit breaker is then evaluated (see Fig .5) in the receiving unit (19).
