Control system for the three-phase refrigerating units

摘要

the control system tru00f3jfazowych aggregates refrigeration having stycznik executive system and detection voltage from a measuring asymmetry is characterized by the fact that two of the measuring arm (p) of the detection phase asymmetry (5) are connected to input pins (l 1, l 2) stycznika executive (2)the third entry measuring limb (p) detection system (5) is connected phase asymmetry to the first end of the control (s0) and by series connection contacts the main other control systems (s1, s2...sn) to the third contact input (l 3) stycznika executive (2), and the other end of the control (s0) is connected to the first end of the coil (2) and a second stycznika implementing end of coils is connected to the mains network (1).
