Abstract
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.
