<p>PROBLEM TO BE SOLVED: To solve the problems that a disconnection part of an existent heavy-current and low-voltage breaker is in a horizontal state, a main circuit terminal of a heavy-current and low-voltage breaker for modification is in a vertical state, when modifying the heavy-current and low-voltage breaker, conventionally, several types of conductors for fastening a conductor in a vertical state and a conductor in a horizontal state are prepared, a method of mutually fastening them is adopted but in the method of mutually fastening several kinds of conductors, since a routing space for fastening the conductors is required which is not required before modification, a separation distance from a proximate grounding metal cannot be secured and further, since much time is required for fastening the conductors, an outage time required for the modification may be significantly increased.SOLUTION: In a structure for connecting a main circuit terminal in a vertical state provided in a heavy-current and low-voltage breaker for modification with a conductor at a main bus side in a horizontal state, a switch gear uses a connection converting conductor to connect the main circuit terminal with the conductor at the main bus side.</p> |
