BENTLY 3500/22M 288055-01 High Frequency Induction Heating Equipment

BENTLY 3500/22M 288055-01 of radiated electromagnetic fields (EMI) is mainly generated by the power network, transient processes of electrical equipment, lightning, radio broadcasting, television, radar, high-frequency induction heating equipment, etc., usually referred to as radiated interference, the distribution is extremely complex. If the PLC system is placed in the radio frequency field, it is recycled to the radiation interference, the impact of which is mainly through two paths: one is directly to the PLC internal radiation, by the circuit inductance of the interference; but rather to the PLC communication within the network of radiation, by the inductance of the communication line of the introduction of interference. Radiation interference with the field equipment layout and the size of the electromagnetic field generated by the equipment, especially the frequency, generally through the setting of shielded cables and PLC local shielding and high-voltage relief elements for protection.

BENTLY 3500/22M 288055-01 is mainly introduced through the power supply and signal lines, usually called conduction interference. This kind of interference is more serious in our industrial site. BENTLY 3500/22M 288055-01 power supply interference caused by the introduction of PLC control system failure in many cases, I have encountered in a project debugging, and then replace the isolation performance of higher PLC power supply, the problem is solved.

BENTLY 3500/22M 288055-01 system’s normal power supply are powered by the grid. As the grid covers a wide range, it will be subject to all space electromagnetic interference and inductance voltage and circuit on the line. In particular, the changes within the grid, into the switching operation surge, large-scale power equipment start and stop, AC and DC drives caused by harmonics, grid short circuit transient shock, etc., are transmitted through the transmission lines to the original side of the power supply. PLC power supply is usually used to isolate the power supply, but the mechanism and manufacturing process factors that make the isolation is not ideal. In fact, due to the presence of distributed parameters, especially distributed capacitance, absolute isolation is impossible.
