Harmonic transmission is the conduction and radiation, to solve the conductive interference is mainly conducted in the circuit to filter the high-frequency current filtered or isolated; to solve the radiation interference is to shield the source or the interference of the line. Specific common methods: (1) inverter power supply system and other equipment independent of the power supply, or in the inverter and other electrical equipment installed on the input side of the isolation transformer , cut off the harmonic current. (2) Connect the appropriate reactor on the input side and the output side of the inverter, or install the harmonic filter. The filter must be of LC type to absorb the harmonics and increase the impedance of the power supply or load to achieve harmonic suppression the goal of. (3) The cable between motor and inverter should be laid with steel pipe or armored cable, laid with other weak signals in different cable ditch to avoid radiation interference. (4) Shielded cable should be used for the signal cable, and the control cable of the main circuit of the inverter must be staggered by a certain distance (at least 20cm or more) during wiring to cut off the radiation interference. (5) The inverter uses a dedicated ground wire, and with a stubby ground, the ground wire adjacent to other electrical equipment must be separate from the inverter wiring and use short-term. This effectively suppresses the radiated interference from current harmonics to nearby devices. LC-RX â… type filter compensation device adopts microcomputer dynamic filter compensation controller, the main circuit adopts high-performance contactor switching filter branch control mode, automatic switching. Equipment is technologically advanced, fully functional, high reliability, easy operation, small maintenance, durability and so on. Tuning filter branch using computer simulation design, analysis and calculation of the actual situation for users, in-place filter compensation to improve the user's power factor and harmonic conditions, to achieve energy saving and improve user economic benefits. Device can automatically exit the work in the event of an external fault or power failure, automatically resume operation after power transmission.
