Abstract
The utility model discloses a 110kV power distribution device breaker double-row arrangement structure with double bus wirings. The 110kV power distribution device buses are flexible leads and are divided into two groups. The first group of buses is divided into two segments which are connected thorough a flexible lead. An incoming circuit breaker and an outgoing circuit breaker are symmetrically arranged at two sides of the bus for forming a circuit breaker double-row arrangement. The arrangement direction of the two groups of buses is vertical with the direction of the incoming/outgoing circuit. A combined frame is adopted for the frames at the left side and the right side in a transformer station. A bus isolation switch is provided below the bus. The 110kV power distribution device breaker double-row arrangement structure with the double bus wirings overcomes the defects in single-row arrangement of the traditional 110kV circuit breaker. The incoming circuit breaker and the outgoing circuit breaker are arranged at two sides of the first group of buses and the second group of buses. The 110kV power distribution device breaker double-row arrangement structure with the double bus wirings has the following advantages: facilitating cross land occupation area reduction of the place, configuring the incoming circuit unit and the outgoing circuit unit in one interval, obtaining compact structure, satisfying the requirement by specific land and user, reducing land occupation area, and facilitating long-term period enlargement.
