Rectifiers have protection from internal and external short circuits (safety devices with operation indicator).
Rectifier Â-ÒÏÏÄ-6.25ê-450 has measuring devices:
- ammeter for output current measurement;
- voltmeter for output voltage measurement;
- device for temperature control ÒÊÏ 160 or ÒÊÏ 100 ÝÊ-1 M with measurement limits from 0 till100 °C.
From the design point of view, rectifier Â-ÒÏÏÄ-6.25ê-900 consists of two cabinets (anode and cathode), rectifier Â-ÒÏÏÄ-6.25ê-450 – from three ones (A, B, C phases), united at the operation area into common design.
Operating rectifiers state – vertical.
Rectifiers have bi-sided service.
Protection degree IP20 according to State Standard 14254.
Climatic version ÓÕË, siting category 4 according to State Standard 15150 .
Rectifiers cooling is forced air. Consumer supplies air rate via air channel in the rated mode, not less than 8103 m3/hours and 1631 Pa. Air duct connection – from above, at the cabinets roof.
