Electromagnetic electronic type composite insulation cross-core type combined sensor

The invention relates to an electromagnetic electronic type composite insulation straight-through type combined sensor, which belongs to the technical field of an electromagnetic electronic type current transformer and voltage transformer deep fusion sensor, and comprises three single-phase combined sensors, a current junction box and a voltage junction box. The single-phase combined sensor is of a cross-core type structure, measurement of A, B and C phases of three-phase electricity is achieved, and a primary conductor shielding net, an electromagnetic current transformer zero sequence coil, an electromagnetic current transformer phase sequence coil, a high-voltage capacitor, a medium-voltage capacitor and the like are arranged in the sensor. The current junction box can convert A, B and C phase currents and zero sequence currents into analog voltage small signals to be output. The voltage junction box can convert A, B and C phase voltages and zero sequence voltages into analog voltage small signals to be ou
