Distribution-circuit intermediate protection integrated device

A distributed-circuit intermediate protection integrated device comprises an incoming line terminal, an incoming line side lightening arrester, a fuse protector, a multifunctional power meter, a current transformer, a current terminal row, a residual current operated circuit-breaker, a common-compensation capacitor switch, a self-healing power capacitor, an outgoing line side lightening arrester and an outgoing line terminal which are all installed in a stainless steel box in sequence. The distribution-circuit intermediate protection integrated device is installed on a low-voltage distribution circuit between distribution unit-area overall protection and household protection, the fault point can be isolated once ground fault occurs to a certain branch circuit, failure outage to other circuits never occurs, and power supply continuity and reliability of residential users is guaranteed; the device has a lightning protection function, an electric leakage protection function, and meter, voltage, current and power factor measurement and reactive local compensation functions; overlapping investment can be avoided, and the distribution-circuit intermediate protection integrated device is timesaving, laborsaving, safe and high in operation efficiency.
