Abstract
The utility model relates to a nuclear phase detector comprising a shell, an indicator light, a nuclear-phase socket and a built-in circuit module. The indicator light is arranged on a shell panel. The nuclear phase detector is characterized in that two electrical signals which are led from the nuclear-phase socket are linearly connected with a phase-comparison circuit in the circuit module and the electrical signals are outputted by the phase-comparison circuit and transmitted to the indicator light after passing through a phase shaping circuit; the nuclear-phase socket corresponds to a three-phase electrical signal leading wire and the three phases correspond to the phase-comparison circuit, the phase shaping circuit and the indicator light respectively. The nuclear phase detector is designed aiming at an inductive high-voltage charge display device, receives a three-phase electrical signal simultaneously and can achieve three-phase nuclear phase functions of two charge display devices at one time. The nuclear phase detector employs an active nuclear phase detector comprising an operational amplifier and improves the accuracy of nuclear phase and fault tolerance by simple circuit processing; and the indicator light is lightened by an external power supply, i.e. an LED, thereby the display is brighter and clearer, which is beneficial to an operator to observe.
