La incorporaci\u00f3n de sistemas de control electr\u00f3nicos ha optimizado la gesti\u00f3n energ\u00e9tica y la automatizaci\u00f3n de los procesos productivos. Estas tecnolog\u00edas, basadas en la conversi\u00f3n de corriente alterna a corriente continua, requieren una protecci\u00f3n adecuada que garantice la seguridad de las personas y de las instalaciones ante posibles fallos en ambas partes del sistema.<\/h4>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row gap=”10″ equal_height=”yes”][vc_column width=”1\/2″][vc_column_text css=”.vc_custom_1783082726004{margin-top: 20px !important;margin-bottom: 20px !important;}”]Esto afecta a equipos habituales como variadores de velocidad, inversores, sistemas de alimentaci\u00f3n ininterrumpida, puntos de recarga de veh\u00edculos el\u00e9ctricos, equipos de ofim\u00e1tica o sistemas LED<\/strong>, presentes tanto en aplicaciones industriales como en el uso diario.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_column_text css=”.vc_custom_1783082706813{margin-top: 20px !important;margin-bottom: 20px !important;}”]A la hora de proteger a las personas y a la propia instalaci\u00f3n<\/strong> frente a posibles fallos o fugas en continua, los dispositivos de protecci\u00f3n diferencial tipo A, AC o F<\/strong> no detectan fugas en corriente continua.

Por este motivo, es tan importante utilizar protecci\u00f3n diferencial tipo B en instalaciones donde puedan aparecer fugas en corriente alterna, corriente pulsante, alta frecuencia o corriente continua.<\/span><\/em><\/h4>\n

Qu\u00e9 criterio usar al instalar diferenciales en serie<\/h2>\n

Cuando instalamos diferenciales en serie, aguas arriba de la carga, la correcta selecci\u00f3n del dispositivo no debe tener en cuenta \u00fanicamente el tipo de carga. Tambi\u00e9n es necesario contemplar otros aspectos que permitan una correcta coordinaci\u00f3n del sistema de protecciones.<\/p>\n

Para garantizar la selectividad vertical<\/strong>, deben cumplirse siempre tres condiciones: amperim\u00e9trica, cronom\u00e9trica y de tipo<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row gap=”10″ equal_height=”yes”][vc_column width=”1\/3″ css=”.vc_custom_1783332114232{background-color: #FFEAEA !important;border-radius: 15px !important;}”][vc_column_text css=”.vc_custom_1783325219353{margin-bottom: 20px !important;padding-top: 20px !important;padding-right: 20px !important;padding-bottom: 20px !important;padding-left: 20px !important;}”]\"Selectividad<\/p>\n

Selectividad amperim\u00e9trica<\/h3>\n

La sensibilidad de un interruptor diferencial<\/strong> siempre debe ser superior a la del que se encuentra aguas abajo. De este modo, en caso de producirse una fuga, actuar\u00e1 primero el dispositivo m\u00e1s cercano al punto de la instalaci\u00f3n afectada, evitando que se desconecte toda la l\u00ednea.<\/p>\n

Para asegurar esta selectividad, se recomienda ajustar la sensibilidad<\/strong> con un valor aproximadamente tres veces mayor<\/strong> que la del diferencial inferior.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″ css=”.vc_custom_1783332148572{background-color: #FFEAEA !important;border-radius: 15px !important;}”][vc_column_text css=”.vc_custom_1783324320794{margin-bottom: 20px !important;padding-top: 20px !important;padding-right: 20px !important;padding-bottom: 20px !important;padding-left: 20px !important;}”]\"Selectividad<\/p>\n

Selectividad cronom\u00e9trica<\/h3>\n

Del mismo modo que ocurre con la sensibilidad, los tiempos de disparo<\/strong> de los interruptores diferenciales tambi\u00e9n deben ser superiores<\/strong> en el dispositivo situado aguas arriba.<\/p>\n

Esto garantiza que, ante una fuga, primero act\u00fae el diferencial m\u00e1s pr\u00f3ximo al punto de fallo. Para mantener la selectividad cronom\u00e9trica<\/strong>, se recomienda ajustar el retardo con un valor aproximadamente dos veces mayor<\/strong> que el configurado en el diferencial inferior.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″ css=”.vc_custom_1783332159043{background-color: #FFEAEA !important;border-radius: 15px !important;}”][vc_column_text css=”.vc_custom_1783324328528{margin-bottom: 20px !important;padding-top: 20px !important;padding-right: 20px !important;padding-bottom: 20px !important;padding-left: 20px !important;}”]\"Selectividad<\/p>\n

Selectividad por tipo de protecci\u00f3n diferencial<\/h3>\n

Otro aspecto importante es la correcta selecci\u00f3n del tipo de protecci\u00f3n diferencial<\/strong>. Este debe ser siempre del mismo tipo o de un tipo superior al instalado aguas abajo.<\/p>\n

De esta forma se asegura la continuidad del servicio y se evitan disparos intempestivos que puedan afectar a toda la instalaci\u00f3n.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”76753″ img_size=”large” alignment=”center” css=”.vc_custom_1783330363629{margin-top: 40px !important;margin-bottom: 40px !important;padding-right: 40px !important;padding-left: 40px !important;}”][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1783068982335{padding-top: 20px !important;padding-right: 20px !important;padding-bottom: 20px !important;padding-left: 20px !important;background-color: #F3F4F5 !important;border-radius: 15px !important;}”][vc_column][vc_column_text css=”.vc_custom_1783333236510{margin-top: 20px !important;margin-bottom: 40px !important;}”]\"Soluciones<\/p>\n
