Title:
PRIMARY SIDE CONNECTION CONDUCTOR OF 2-POLE BREAKER FOR DISTRIBUTION BOARD
Document Type and Number:
Japanese Patent JP2819541
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide connection conductors with which the primary terminals of breakers are connected to the main bus-bars of respective phases while sufficient insulation spacings between connection conductors are maintained without providing additional insulators between them even if the distances between the primary side terminals of the adjacent breakers are very small.
SOLUTION: The primary side terminals 5a and 5b, 6a and 6b,... and 12a and 12b of breakers 5-12 are connected to main bus-bars 2, 3 and 4 with 3 types of connection conductors 13, 14 and 15. That is, the connection conductors 13, 14 and 15 have 1st connection parts 13a, 14a and 15a of the main bus-bars 2, 3 and 4 sides and 2nd and 3rd connection parts 13c, 13d, 14e, 14f, 15e and 15f of the primary side terminals 5a and 5b, 6a and 6b,... and 12a and 12b sides of the breakers 5-12. With this constitution, it is not necessary to connect the respective breakers 5-12 to the main bus-bars 2, 3 and 4 individually and hence the congestion of the connection conductors can be eliminated, so that the insulation spacings between the connection conductors can be maintained without providing additional insulators between them.
