1-It has the advantages of high efficiency, low flow resistance, antibacterial, energy saving, etc.
2-Filter material fabric with charged, combined with the dense characteristics of melt blown superfine fiber material, a large number of
electrodes are formed between the charged fabrics;
3-Improve the filtration efficiency of melt blown farbic to make it reach the standard and improve the quality of meltblown fabric;
(1) Input power detection and voltage regulator return to zero.
(2) Connect the three-phase power line and the neutral line to the corresponding terminal on the back of the test bench, and the test transformer reliably grounds the ground bolt of the test bench cabinet;
(3) Close the external power switch;
(4) Turn the "master control power switch" to the "on" position. At this time, the red light of the "power indication" switch cabinet power-on test bench, all meters and the "green light of the button with light" are on.
(5) Turn the "three-phase four-wire power supply voltage conversion switch" to "CA", "BC", and "AB" to display the corresponding line voltage (380V).
(6) The zero return operation of the regulator:
