The three-phase fuse cartridges are arranged in an inverted triangular structure, and are completely sealed with the air box surface with a sealing ring, which can ensure that they are not affected by the external environment. As long as the striker is triggered after one phase fuse is fused, the load switch will be opened by quick tripping, so as to ensure that the transformer will not have the risk of phase loss operation.
The combination mode of vacuum circuit breaker +three position disconnecting switch is adopted, which is mainly used to set reliable mechanical interlocking between the vacuum switch and the disconnecting switch such as the connection, branch and control of cable lines and small capacity transformers, so as to prevent mis-operation and ensure that the circuit breaker can open and close the load current.
