O que \u00e9 o aparelho de teste BDV para transformadores?<\/strong><\/p>\n\n\n\n

Teste BDV<\/strong> significa o Teste de tens\u00e3o de rutura<\/strong>. Este ensaio \u00e9 realizado para verificar a rigidez diel\u00e9ctrica do \u00f3leo do transformador. A rigidez diel\u00e9ctrica \u00e9 a capacidade m\u00e1xima de resist\u00eancia \u00e0 tens\u00e3o do \u00f3leo isolante.<\/p>\n\n\n\n

An\u00e1lise da varia\u00e7\u00e3o do valor da tens\u00e3o de rutura no teste Quando a tens\u00e3o de rutura do \u00f3leo do transformador \u00e9 testada, geralmente uma ch\u00e1vena de \u00f3leo \u00e9 testada 5 vezes e o valor m\u00e9dio \u00e9 obtido.<\/p>\n\n\n\n

Como funciona o medidor de BDV do \u00f3leo?<\/strong><\/p>\n\n\n\n

O funcionamento normal deve ser o seguinte: depois de o \u00f3leo de ensaio estar cheio, deixar repousar durante 10 minutos e, em seguida, efetuar o ensaio de ascens\u00e3o. Ap\u00f3s cada avaria, utilizar a vareta de vidro limpa preparada para fazer algumas vezes entre os el\u00e9ctrodos ou vibrar suavemente o copo de \u00f3leo para obter danos. A ponte rec\u00e9m-formada entre os el\u00e9ctrodos pode ser deixada durante 5 minutos para o ensaio seguinte.<\/p>\n\n\n\n

Prestar aten\u00e7\u00e3o ao utilizar o aparelho de teste da tens\u00e3o de rutura do \u00f3leo:<\/strong><\/p>\n\n\n\n

A primeira vez que a tens\u00e3o de rutura \u00e9 extremamente baixa: o primeiro teste pode ter alguns fatores externos causados pela inje\u00e7\u00e3o de \u00f3leo no copo de \u00f3leo ou na superf\u00edcie do eletrodo do copo de \u00f3leo antes da inje\u00e7\u00e3o de \u00f3leo, de modo que o primeiro valor \u00c9 baixo, por isso \u00e9 necess\u00e1rio realizar o sexto teste e tirar a m\u00e9dia de 2 a 6 vezes.<\/p>\n\n\n\n

Este aparelho de teste de \u00f3leo de transformador bdv<\/strong> satisfaz v\u00e1rias normas, selecionar a norma adequada e necess\u00e1ria para o ensaio.<\/p>\n\n\n\n
