THYRISTOR RADIATOR ASSEMBLY FOR DC VEHICLE SAFETY VALVE Russian patent published in 2018 - IPC H01L23/473 H01L23/367 H03K17/72 

FIELD: electrical engineering.

SUBSTANCE: invention is used in operation of DC transmission safety valves and in particular represents thyristor radiator assembly for DC safety valve. Hole for draining water from radiator N communicates with drainage hole from radiator (N-2). Hole for water inlet into radiator N communicates with water inlet to radiator (N+2). Either water inlet to radiator N communicates with water inlet to radiator (N-2), and drainage port of radiator N communicates with drainage port of radiator (N+2). Hole for draining water from radiator M communicates with drainage port of radiator (M-2), and water inlet to radiator M communicates with water inlet to radiator (M+2). Either water inlet into radiator M communicates with water inlet to radiator (M-2), and drainage port for water from radiator M communicates with drainage port of radiator (M+2). Holes for water inlet of last two radiators communicate with each other. Depending on parameters of radiator, number of connections of cooling system decreases, risk of leakage decreases, reliability of converter valve operation is improving, maintenance is simplifying and the time required to carry it out is reducing.

EFFECT: improved design of thyristor radiator assembly for DC safety valve is made.
