    • A distribution switchgear has an equipment room, main busbar room and cable room, which are formed in a distribution panel housing by partitioning the housing, from front to back such that the equipment room is located just behind the front door of the housing, with the busbar room behind the equipment room. In the equipment room, are disposed a circuit breaker, a current transformer on a load side of the circuit breaker and a zero-phase-sequence current transformer on a power supply side of the circuit breaker. The equipment units are vertically arranged in the equipment room. In the busbar room are a solid-insulated main busbar, a solid-insulated link busbar connected with the main busbar and connected with one side of each of the equipment units and a solid-insulated branch busbar connected with the other side of each of the equipment units.
    • 分配开关设备具有设备室,主母线室和电缆室,它们通过从前到后分隔壳体而形成在配电盘壳体中,使得机房位于壳体的前门正后方, 工作室后面的母线室。 在设备室中,在断路器的负载侧设置断路器,电流互感器和断路器的电源侧上的零相电流互感器。 设备单元垂直布置在机房内。 母线室是一个固体绝缘主母线,一个固定绝缘连接母线与主母线连接,并与每个设备单元的一侧连接,而固体绝缘分支母线与每个母线的另一侧相连 设备单位。
