Three -phase balance high pressure metering device

The utility model discloses a three -phase balance high pressure metering device, including special combined mutual inductor, phase change switch module, taking accuse strapping table case and intelligent monitor terminal, the electric wire netting inlet wire inserts subordinate's user side electric wire netting through the output of special combined mutual inductor, the phase change switch module is installed on each branch line of subordinate's user side electric wire netting for load on the adjustment branch line, intelligence monitor terminal installs and holds at the electric wire netting inlet wire for detect unbalanced three phase, in case intelligent monitor terminal unbalanced three phase appears on detecting the circuit, the load that sends on the control command control phase change switch module adjustment branch line makes the three -phase balanced again. Adopt the technical scheme of the utility model, owing to increase intelligent monitor terminal at the inlet wire end, can in time detect unbal
