Rectifier cubicle with liq.-cooled rectifier modules - has horizontal guide and coupling rail profiles for modules on rollers

摘要

In addition to the rectifier modules, the cubicle contains current rails for contacting electric terminals of the modules, and a frame for forming a liq. cooling circuit. Horizontal coupling rail profiles serve for guiding rectifier modules (22) with running rollers for inserting into and withdrawal from the cubicle (1). The vertical front current rails (5) are fitted with run-up members (4), engaged by module run-up contacts (3) after module insertion. The vertical, rear support and liq, conducting profiles (7) have rapid closure couplings (12) for a hydraulic coupling of the modules to the cooling liq. circuit, after the module insertion. USE/ADVANTAGE - Three-phase railway traction drives. Modular construction allows exchange of separate units, esp. components contg. rectifying valves.
