Abrégé

This solar power generation network shut-off unit (1) comprises a first breaker (20) and second breakers (30). The first breaker (20) is provided in a power line (14) that connects a plurality of solar power generation modules (11) and a power conditioner (12) in series, and when an emergency shut-off button (13) is operated, the supply of power from the solar power generation modules (11) through the power line (14) is shut off, and an emergency shut-off signal is transmitted. The second breakers (30) are each provided to each of the plurality of solar power generation modules (11), and when the emergency shut-off signal is received from the first breaker (20), the second breakers (30) shut off the supply of power from the plurality of solar power generation modules (11) through the power line (14).

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
