Abstract

EN UN TRANSFORMADOR DE ALTA TENSION, ESENCIALMENTE UN TRANSFORMADOR DE BARRIDO HORIZONTAL DE DIODOS, EXISTE GENERALMENTE LA EXIGENCIA DE DIMENSIONAR LA DISPOSICION COMPLETA EN LO POSIBLE DE FORMA REDUCIDA POR MOTIVOS DE COSTES Y PESOS, ASIMISMO DEBEN EVITARSE LAS PERDIDAS DE CALOR DURANTE EL SERVICIO DE SEMEJANTE TRANSFORMADOR DE ALTA TENSION, DE TAL FORMA QUE EL CALENTAMIENTO DEL TRANSFORMADOR NO ALCANCE MARGENES DE TEMPERATURA, EN EL QUE OTROS COMPONENTES DEL CIRCUITO DE UN RECEPTOR DE TELEVISION PUEDAN SER DAÑADOS O PERTURBADOS. EL COMETIDO DE LA INVENCION ES EL DE REDUCIR LAS PERDIDAS DE UN TRANSFORMADOR DE ALTA TENSION, ESPECIALMENTE DE MINIMIZAR LAS PERDIDAS ELECTRICAS. SEGUN LA INVENCION, SE SOLUCIONA EL COMETIDO PARA UN TRANSFORMADOR DE ALTA TENSION DEL TIPO CITADO MAS ARRIBA, DE TAL MANERA QUE ENTRE EL ARROLLAMIENTO PRIMARIO Y EL ARROLLAMIENTO DE LA ALTA TENSION, SE HA CONCEBIDO UN ESPACIO CASI LIBRE DE CAMPO. RECEPTORES DE TELEVISION, ESPECIALMENTE RECEPTORES DE TELEVISION DE MUCHAS LINEAS EN LA NORMA ESTANDAR HDTV.IN A HIGH VOLTAGE TRANSFORMER, ESSENTIALLY A HORIZONTAL DIODE SWEEPING TRANSFORMER, THERE IS GENERALLY A REQUIREMENT TO DIMENSION THE COMPLETE DISPOSITION IN A WAY OF REDUCING COSTS AND WEIGHTS, SO AS TO AVOID THE CAUSES OF COSTS AND HEAVY DURATION. HIGH VOLTAGE TRANSFORMER, SO THAT THE TRANSFORMER'S HEATING DOES NOT REACH TEMPERATURE MARGINS, IN WHICH OTHER COMPONENTS OF THE CIRCUIT OF A TELEVISION RECEIVER MAY BE DAMAGED OR DISTURBED. THE PURPOSE OF THE INVENTION IS TO REDUCE LOSSES OF A HIGH VOLTAGE TRANSFORMER, ESPECIALLY TO MINIMIZE ELECTRICAL LOSSES. PURSUANT TO THE INVENTION, THE ROLE FOR A HIGH-VOLTAGE TRANSFORMER OF THE ABOVE TYPE, IN THE WAY THAT BETWEEN THE PRIMARY WINDING AND THE HIGH-VOLTAGE WINDING, HAS BEEN DESIGNED ALMOST FREE FIELD. TELEVISION RECEIVERS, ESPECIALLY TELEVISION RECEIVERS OF MANY LINES IN THE STANDARD STANDARD HDTV.
