分電盤の分岐回路接続チェック装置
Document Type and Number:
Japanese Patent JP5505887
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a check apparatus capable of saving labor for a connection check of a distribution board and wiring.SOLUTION: A check apparatus is comprised of: a distribution board 1 including a plurality of branch breakers 6-9; a master unit 22 including means 16-20 for measuring a change in electrification current for each of the branch breakers 6-9, and a means 21 for transmitting the electrification current for each of the branch breakers 6-9 in which a change of the electrification current has been measured, to a slave unit 56; the slave unit 56 including a means 49 for receiving a transmit signal from the master unit 22 and a means 50 for displaying the electrification current for each of the branch breakers 6-9; and a load device 45 connected to a wiring terminal for each of the branch breakers 6-9. The branch breaker 6-9 to which the load device 45 is connected, is specified. Furthermore, the master unit 22 includes a zero-phase current measuring means 11 of a trunk, the slave unit 56 includes a resistance means 53 connected between a voltage electrode and a ground electrode of the wiring terminal, and a means 50 for displaying a zero-phase current of the trunk, and the zero-phase current is read by the slave unit 56, thereby confirming a connection state between the ground electrode of the wiring terminal and the ground.
