Compatible teaching experimental instrument for transmission electromagnet with three-phase system

A compatible teaching experimental instrument for transmission electromagnet with a three-phase system can measure overall noise, common mode noise and differential mode noise of a device to be measured and has a selection function of a noise suppressing filter. The technical scheme adopted for resolving the technical problem is that the compatible teaching experimental instrument for transmission electromagnet with a three-phase system comprises a function module part and a control part, wherein the function module part is used for actuating functions of noise detection, noise separation and noise suppression and comprises a line impedance stabilization network (LISN) module, a filter module and a noise separation module, and the control module is a circuit used for controlling three-phase input, selecting filters and displaying working conditions of each function module. The compatible teaching experimental instrument for transmission electromagnet with a three-phase system is provided with a rectangular insulation casing (WK), and a control button, a switch, an indicating lamp, a function sign and a three-phase five-wire socket are arranged on the front side of the teaching experimental instrument. The compatible teaching experimental instrument is convenient to operate, high in reliability, capable of satisfying requirements for detecting and suppressing transmission interference noise of teaching experiment and favorable for enabling students to understand experimental theory and grasp experimental methods.
