Definitions

  • WO 201 1 /005 254 A1 discloses a system for monitoring a switchgear.
  • At least one physical value is a value of temperature measured by a temperature sensor.
  • the sensor unit is connecting temperature sensors to get infor mation about an electrical connection between two conductors. Temperature moni toring can be done at bus bar joints, inside of a module, especially inside of a with drawable module, at incoming and outgoing contacts or at outgoing cable termina tion. Also temperature inside or outside of a switchgear or of a withdrawable module can be detected.
  • one information is a position of a device detected by a posi tion sensor.
  • the location of a withdrawable module or the number of insertions of modules can be detected.
  • Position sensors detect inserted, isolated and/ or removed positions of devices. By this mechanical conditions and electrical connection condi tions can be detected. It is also possible to count insertion cycles of a module, espe cially of a withdrawable module, by a position sensor. So it can be predicted when a module has to be replaced. It can be detected or predicted if power contacts are still sufficient. This makes maintenance easier. It can also be detected if the correct de vice or module is installed in the switchgear or if some components, especially of the module, are missing.
  • At least one sensor unit comprises at least one own sensor or sev eral own sensors. So temperature, voltage, current, humidity or position can also be detected by the sensor unit.
  • the switchgear comprises a housing and a withdrawable module or plug-in module, whereas the withdrawable module or plug-in module is insertable or inserted in a reversible manner in the housing, whereas the sensor unit is mechani cally attached to the module or to the housing.
  • the sensor unit can be installed inside of the module or above the module.
  • the sensor unit can be used to monitor the tem perature within the module.
  • the sensor unit can be installed outside of a withdrawa- ble or plug-in-module.
  • the sensor unit can be installed inside of a cable connection unit.
  • the switchgear comprises a housing and a withdrawable module or plug-in module, whereas the withdrawable module or plug-in module is insertable or inserted in a reversible manner in the housing, whereas at least one sensor is mechanically attached to the module or to the housing.
  • the sensor unit communicates via serial communication, e.g. Mod- bus, or ethernet communication, e.g. Modbus TCP, OPC UA, https etc., to a monitor ing system.
  • Serial communication e.g. Mod- bus
  • ethernet communication e.g. Modbus TCP, OPC UA, https etc.
  • Condition based and predictive maintenance calculations can be done by the moni toring system.
  • a sensor can be connected to the sensor unit by short range RFID.
  • Fig. 1 schematically shows a low voltage switchgear, comprising sensors and sensor units connected to the sensors, whereas the sensor units com municate to a monitoring system,
  • Fig. 2 schematically shows a withdrawable module which carries a sensor that is connectable to a sensor unit installed in a housing according to Fig. 1 , and
  • Fig. 3 schematically shows a withdrawable module, whereas a sensor unit which is installed in the housing is connectable to a sensor also installed in the housing according to Fig. 1.
  • At least one physical value is a value of temperature measured by a temperature sensor 2a. At least one physical value is a value of humidity measured by a humidity sensor 2b. One physical value is a value of current or voltage detected by a current or voltage sensor 2c. One information is a position of a device detected by a position sensor 2d.
  • the first sensor unit 3a is developed as a separate part which can be added as one assembly to an existing device or to an existing switchgear 1 .
  • the sensor unit 3a is developed as a drawer.
  • the sensor unit 3a carries a QR-Code or a serial number.
  • Fig. 2 schematically shows a switchgear 1 , comprising at least one sensor 2e, whereas one sensor unit 3b is connected to the at least one sensor 2e to get or to read out at least one physical value measured by the at least one sensor 2e.
  • Sensor 2e is a further temperature sensor 2e.
  • This further temperature sensor 2e is attached to the module 5 or is installed inside of the module 5.
  • the sensor unit 3b is connected to the sensor 2e. So are as of high temperature can be detected. Especially areas of high temperature inside of the module 5 can be detected.

Abstract

L'invention porte sur un appareillage de commutation (1), comprenant au moins un capteur (2a-e) ou plusieurs capteurs (2a-e), caractérisé en ce qu'au moins une unité de capteur (3a, 3b) est connectée ou peut être connectée à au moins un capteur (2a-e) ou aux capteurs (2a-e) pour obtenir ou lire au moins une valeur physique mesurée par au moins un capteur (2a-c, 2e) et/ou d'autres informations détectées par au moins un capteur (2d), qui atteint l'objectif de surveiller l'état d'un appareillage de commutation d'une manière aussi large ou étendue que possible afin d'effectuer une maintenance lorsque cela est nécessaire. Cet objectif est également atteint par un procédé pour effectuer la maintenance prédictive d'un appareillage de commutation (1).
