STQ (M) L series rectifier control equipment
- Product description: STQ (M) L series rectifier control equipment
STQ(M) series products have the advantages of stable performance and easy maintenance. This series of products pass through the three-phase bridge rectifier module through the transformer to obtain dc 220v voltage from the ac power supply. The whole equipment is composed of automatic air switch, transformer, three-phase bridge rectifier module, dc contactor and other main components. The circuit is equipped with short circuit, overvoltage and other protective measures, when the controlled electromagnet capacity is greater than 19 KWH, the rectifier transformer external attachment; When the controlled electromagnet capacity is less than or equal to 4 KWH, single-phase bridge rectifier is adopted.
This series of control cabinet is to reduce the voltage of three-phase ac power supply from rectifier transformer, and then get the dc 220V voltage through single-phase (three-phase) bridge rectifier unit. The whole control cabinet consists of automatic air switch, rectifier transformer, rectifier unit, dc contactor and other main components; The circuit is provided with short circuit, overvoltage and other protective measures; It has the characteristics of simple structure, small volume, light weight, reliable operation and convenient maintenance.
The rated capacity of the control cabinet is 19kw, and the rectifier transformer with cover is attached; The improved type does not have rectifier transformer. Dc is obtained by bridge rectification of three-phase ac power supply.
