  • the invention relates to a switching device for a high-voltage circuit breaker, the high-voltage circuit breaker, and a method for operating the switching device, wherein the switching device comprises at least two switches for determining states of devices of the switching device via a monitoring system.
  • High voltage circuit breakers such as B. from the EP 2 466 604 A1 known, generally switch in three phases, ie three current paths over three poles are closed or opened simultaneously by three interrupter units operating in parallel, one interrupter unit per pole, during a switching operation. Voltages of up to 1200 kV and/or currents of up to a few hundred amperes can be switched per phase. In order to be able to switch the three phases at the same time, there are two designs of high-voltage circuit breakers. In a first design, a common drive, in particular a spring storage drive, is mechanically connected to the three interrupter units. A high-voltage circuit breaker for switching three phases with one drive is e.g. B. from the DE 10 2010 011 198 A1 known.
  • each interrupter unit is moved by its own drive, in particular by a spring-loaded drive.

  • each of the motor limit switches is electrically connected to a digital input of the monitoring system.
  • the logical link is made in the monitoring system.
  • Monitoring the condition of a high-voltage circuit breaker also includes sensors such as: B. for measuring temperatures, humidity, pressure, vibrations, current/voltage states, and/or resistances, e.g. B. for measuring contamination on an insulator surface.
  • the sensors are also electrically connected to the monitoring system and usually each require a separate input.
  • the use of more than one monitoring system, e.g. B. in the form of two or more sensor boxes, increases costs and space consumption as well as effort.
  • a development and use of monitoring systems with additional inputs also increases costs and effort, and reduces savings from e.g. B. Scaling effects combined with the quantities produced by the respective monitoring systems.

  • the at least two switches can each be motor limit switches, which represent the state of a respective one Storage spring for a drive of an interrupter unit.
  • a signal can be present at the input of the monitoring system, which clearly identifies the condition. This means that the high-voltage circuit breaker is fully ready for use and can be switched for all poles, in particular with an off-on-off switching sequence.

B. include elements of a kinematic chain, connected to the switches for determining states of the devices. Alternatively or additionally, the connection can also be made electrically, electronically or through data transmission, in particular optically. Actuation of the respective switch can in particular be electrical, electromagnetic and/or mechanical, e.g. B. after transmission and / or conversion of signals from the assigned device, the states of which can be determined via the switching device.
  • One, two or more switching devices according to the invention can also be used, e.g. B. two on two digital inputs of a monitoring system.
  • This allows e.g. B. several identical or different types of devices, e.g. B. isolators and interrupter units can be monitored independently of one another.
  • There can also be several high-voltage circuit breakers and/or other high-voltage devices, e.g. B. be monitored on a control panel with one or more switching devices according to the invention. Additional sensors can alternatively or additionally be monitored, in particular by a monitoring system connected to the switching device according to the invention.
  • the circuits of the switching devices can also be modified, e.g. B. supplemented by additional switches for additional tasks or instead of using switches, components, in particular semiconductor components such as. B. transistors or integrated circuits can be used.
