Abrégé

A photovoltaic power generation network cut-off unit (1) is provided with a first breaker (20) and second breakers (30). The first breaker (20) is provided in a power line (14) that connects a power conditioner (12) and a plurality of photovoltaic power generation modules (11) in series, and when an emergency cut-off button (13) is operated, cuts off power supply from the photovoltaic power generation modules (11) through the power line (14) and transmits an emergency cut-off signal. The second breakers (30) are each provided to each plurality of the photovoltaic power generation modules (11), and when receiving the emergency cut-off signal from the first breaker (20), cuts off the power supply from the plurality of photovoltaic power generation modules (11) through the power line (14) and transmits a cut-off completion signal to the first breaker (20).

Classes IPC  ?

  • H02J 13/00 - Circuit arrangements for providing remote indication of network conditions, e.g. an instantaneous record of the open or closed condition of each circuitbreaker in the network; Circuit arrangements for providing remote control of switching means in a power distribution network, e.g. switching in and out of current consumers by using a pulse code signal carried by the network
  • H02H 3/00 - Emergency protective circuit arrangements for automatic disconnection directly responsive to an undesired change from normal electric working condition, with or without subsequent reconnection
  • H02H 7/20 - Emergency protective circuit arrangements specially adapted for specific types of electric machines or apparatus or for sectionalised protection of cable or line systems, and effecting automatic switching in the event of an undesired change from norm for electronic equipment
  • H02H 7/26 - Sectionalised protection of cable or line systems, e.g. for disconnecting a section on which a short-circuit, earth fault, or arc discharge has occurred
