From the design point of view, rectifier is carried out as viewed rectifier cabinet and separate match transformer. Rectifier cabinet has one-sided service. Switching supply cables and overload is performed from below. Cooling – natural air at overload currents till 700 A and forced air one with built-in fan at overload currents is over 700 A.
Operating rectifiers state – vertical
Protection degree IP20 according to State Standard 14254. Climatic version ÓÕË, siting category 4 according to State Standard 15150 (ambient temperature +1 ° +35 °C, air humidity 80 % at +25 °C).
