Arrangement of the cooling water circuit in the dc circuit of a converter

摘要

The arrangement comprises a central metal and earthed water feed pipe (1), a central metal and earthed water draining pipe (2) as well as insulated, hose-typed connections to the cooling water terminals of the cooling arrangements for the electrical devices. On each of the D.C. terminals of the rectifier a metal feed distributor (3, 5) is connected through an insulated intermediate piece (23, 25) to the central feed pipe and a metal draining collector (4, 6) is connected through an insulated intermediate piece (24, 26) to the central draining pipe, connected by the lines (19, 20). The distributors and the collectors extend through insulated, hose-type connections (27, 28) to the cooling water terminals (29) mentioned. USE/ADVANTAGE - Reduction in erosion of anodes as result of d.c. loading. Electro-plating.
