Abstract

"TRANSFORMADOR DE DISTRIBUIçãO AUTO-PROTEGIDO POR UM DISPARO DE DISJUNTOR DE CIRCUITO EM UM CURTO-CIRCUITO SECUNDáRIO". Um transformador de distribuição trifásica 10 compreende, dentro de um tanque estanque 12, que contém um óleo de alta resistência dielétrica, um circuito elétrico primário 16 e um circuito elétrico secundário 18. Um disjuntor de circuito é conectado em série entre as buchas primárias 20 e os enrolamentos primários 24, de modo a cortar o suprimento de energia elétrica para os enrolamentos primários 24, no caso de uma falha elétrica. Meios de disparo 40 executam o disparo do disjuntor de circuito. Esses meios compreendem relés eletromecânicos de sobrecorrente 42 sensíveis às correntes que fluem nas fases 34 do circuito secundário do transformador e, possivelmente, um transdutor 44 sensível à pressão do fluido dielétrico e/ou um transdutor 46 sensível à temperatura do fluido dielétrico. Um sistema cinemático 50 executa a transmissão para o disjuntor de circuito 28 das ordens de disparo que vêm dos diferentes relés eletromecânicos 42 e dos transdutores 44, 46."DISTRIBUTION TRANSFORMER SELF PROTECTED BY A CIRCUIT BREAKER SHOT IN A SECONDARY SHORT CIRCUIT". A three-phase distribution transformer 10 comprises, within a watertight tank 12, containing a high dielectric strength oil, a primary electrical circuit 16 and a secondary electrical circuit 18. A circuit breaker is connected in series between primary bushings 20 and primary windings 24 so as to cut off the power supply to primary windings 24 in the event of an electrical failure. Tripping means 40 trip the circuit breaker. Such means comprise current sensitive electromechanical relays 42 that flow in phases 34 of the transformer secondary circuit and possibly a dielectric fluid pressure sensitive transducer 44 and / or a dielectric fluid temperature sensitive transducer 46. A kinematic system 50 performs the transmission to circuit breaker 28 of the trip orders coming from the different electromechanical relays 42 and transducers 44, 46.
