C\u00f3mo Aumento Excesivo De Temperatura Edades Transformador De Aislamiento?\u00a0<\/b><\/h1>\n

\u2014 Integral de M\u00e9todos para el Control de la Subida de la Temperatura<\/b><\/h4>\n

Los transformadores son el n\u00facleo de los equipos de los sistemas de energ\u00eda, y su temperatura de funcionamiento afecta directamente a la vida \u00fatil de los materiales de aislamiento y rejilla de seguridad. La investigaci\u00f3n por la Comisi\u00f3n Electrot\u00e9cnica Internacional (IEC) indica que el aumento excesivo de temperatura es la principal causa de transformador de fracasos. En este art\u00edculo se profundiza en la relaci\u00f3n entre el aumento de la temperatura y aislamiento de envejecimiento y proporciona un completo proceso de control de la temperatura de la soluci\u00f3n compatible con las normas internacionales (IEC\/IEEE), ayudando a extender la vida \u00fatil de los equipos de m\u00e1s de 10 a\u00f1os.<\/p>\n

1. \u00bfC\u00f3mo Afecta La Subida De La Temperatura “Matar” Transformador De Aislamiento? \u2014 Irreversible De Los Mecanismos De Envejecimiento<\/em><\/b><\/h3>\n

1.1 N\u00facleo de la Ley de Envejecimiento T\u00e9rmico: Arrhenius Efecto<\/strong><\/i><\/h4>\n

La vida \u00fatil de los materiales de aislamiento decae exponencialmente con la temperatura. Como transformador de la temperatura aumenta, molecular movimiento t\u00e9rmico se intensifica, llevando a un aumento exponencial en romper el v\u00ednculo de la probabilidad y el eventual colapso de la estructura. De esta manera se sigue la ecuaci\u00f3n de Arrhenius:<\/p>\n

L = L\u2080 \u00d7 e^(-E\u2090\/kT)<\/b><\/p>\n

L:vida \u00fatil (a\u00f1os) a la temperatura T<\/p>\n

T:Hotspot temperatura absoluta (Kelvin = \u00bac + 273)<\/p>\n

E\u2090:energ\u00eda de Activaci\u00f3n de la material (Julios)<\/p>\n

k:constante de Boltzmann (1.38 x 10-23 J\/K)<\/p>\n

Conclusi\u00f3n clave: Por cada 6 a 10\u00b0C de aumento, el aislamiento, la esperanza de vida se acorta por ~50%. Por ejemplo, aislamiento de Clase B de funcionamiento a 130\u00b0C se ver\u00e1 su vida gota a partir de 20 a\u00f1os a 10 a\u00f1os en la 138\u00b0C.<\/p>\n\n\n\n\n\n\n\n

1.2 Triple de los Mecanismos de Da\u00f1o de las Altas Temperaturas<\/strong><\/i><\/h4>\n
(1)Resistencia Mec\u00e1nica Colapso:A 130\u00b0C, con aislamiento de papel de resistencia a la tracci\u00f3n disminuye en 80% (IEEE C57.91).<\/strong><\/h6>\n
(2)Diel\u00e9ctrico Degradaci\u00f3n del Rendimiento: Por cada 10\u00b0C de aumento, p\u00e9rdida diel\u00e9ctrica aumenta un 300%.<\/strong><\/h6>\n
(3)Aceite-Papel Sin\u00e9rgico Deterioro: las Altas temperaturas aceleran el aceite de la oxidaci\u00f3n. Cuando el \u00e1cido valor excede de 0,5 mgKOH\/g, aislamiento de papel de la esperanza de vida se acorta por 60<\/strong>%.<\/h6>\n

2. Tres Causas de Aumento Excesivo de Temperatura y Soluciones<\/em><\/b><\/h3>\n

2.1 Excesivo de la Corriente de Carga que Conduce a la P\u00e9rdida de Cobre<\/strong><\/i><\/h4>\n

Cuando el transformador de carga excede la capacidad de dise\u00f1o, la corriente de la bobina aumenta. Por la ley de Joule (P=I2R), p\u00e9rdidas resistivas lugar cuadr\u00e1ticamente con la actual, convertir directamente en calor y elevar la temperatura de la bobina.<\/p>\n

2.1.1 Impacto:<\/strong><\/h5>\n
(1)10% de aumento actual \u2192 21% mayor p\u00e9rdida de cobre \u2192 ~15\u00b0C de aumento de temperatura.<\/strong><\/h6>\n

2.1.2 Estudio De Caso:<\/strong><\/h5>\n

Un 110kV transformador del 20% de sobrecarga durante 3 a\u00f1os vio aislamiento de papel de polimerizaci\u00f3n de la ca\u00edda de 40% de su valor inicial, obligando a la jubilaci\u00f3n anticipada.<\/p>\n

2.2 Eficiencia Del Sistema De Refrigeraci\u00f3n Descenso<\/strong><\/i><\/h4>\n

(2)Ventilador de fallos:Paros de elevar la temperatura del aceite por 20\u00b0y 30 \u00b0 C.<\/strong><\/h6>\n
(3)de la Bomba de ineficiencia:Baja de aceite, aumenta el flujo de hotspot temperaturas de 40\u00b0C+.<\/strong><\/h6>\n
2.2.2 Consecuencia:<\/strong><\/h5>\n

La acumulaci\u00f3n de calor conduce a una aver\u00eda del aislamiento.<\/p>\n

2.3 Temperaturas Ambiente Altas<\/strong><\/i><\/h4>\n

La temperatura ambiente afecta directamente a la eficiencia de refrigeraci\u00f3n.<\/p>\n

(1)Impacto:Cada 1\u00b0C de aumento en la temperatura ambiental aumenta interna temps por 0,5\u20131\u00b0C. luz del Sol puede aumentar superficie del tanque temperaturas de 20\u00b0C+.<\/strong><\/h6>\n
(2)Estudio de Caso:Una subestaci\u00f3n en \u00c1frica requiere de un 15% de reducci\u00f3n de la carga a 40\u00b0C para garantizar la seguridad de la operaci\u00f3n.<\/strong><\/h6>\n
