Process Of\u00a0A Transformer Explosion<\/strong><\/h4>\n

Caused by aging (cumulation of moisture and suspended particles, creation of acids), the insulating oil loses the dielectric features.<\/p>\n

This can\u00a0lead to a sparkover, an electric arc is created. The arc vaporizes the insulating oil which has now, as gas, a considerable bigger volume:\u00a0Shock waves are created.\u00a0\u00a0These shockwaves superimpose and lead to high static pressure – the tranformer housing is not able to compensate this pressure\u00a0and bursts, the transformer explodes. From the first pressure peak to the explosion, it takes milliseconds only. Both, Buchholz Relay and pressure vent,\u00a0react much too slow to prevent the transformer housing from bursting.<\/p>\n

Process Of Transformer Protector TP<\/strong><\/h4>\n

Transformer Protector TP is a passive, mechanical system and is put into operation by the first shockwafe – even before any static pressure can be generated.<\/p>\n

Every TP model includes beyond others a bursting disc and a gas \/ oil collecting tank. In less than 2\u00a0milliseconds, the dynamic pressure peak activates the pressure reduction unit\u00a0– oil and gas are led into separate containers.\u00a0Contact of the high explosive gases hydrogen and acetylene and ambient air is excluded.<\/p>\n

Surveys of the CEPEL Laboratory in Brazil and of\u00a0Electricit\u00e9 de France have shown that the pressure inside a transformer has reached a noncritical level within three milliseconds after activation of the TP already.<\/p>\n

By automatic or manual feeding of nitrogen into the\u00a0tank and the instruments nearby, a safe environment for the quick repair of the transformer can be achieved.<\/p>\n
