Abstract

The invention discloses a distribution transformer tank type oil storage and pressure relief indicator which comprises an oil storage cavity communicated with the interior of an oil-immersed full-sealed transformer body, and the oil storage cavity can be used for containing transformer oil. The transformer has an oil storage function, ensures that the transformer body is full of oil, and prevents an iron core, a winding and a tap switch tap from being exposed in the air to be damped and aged due to oil shortage and the transformer from being burnt out due to temperature rise during high-load operation; meanwhile, the functions of releasing (fault gas in the transformer) pressure and indicating the oil level are achieved; by additionally arranging the rain skirt, rainwater and humid air can be prevented from entering the transformer to cause burnout due to turn-to-turn short circuit of the C-phase winding.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transformer tank type oil storage pressure release indicator. Background technique [0002] Most of the oil-immersed hermetic transformers operating in the distribution network system are oil-immersed hermetic transformers. In the oil tank shell of oil-immersed hermetic transformers, YW series tubular oil level indicators are generally used, and YW series tubular oil level indicators are generally used. The indicator is installed on the upper part of the transformer oil tank cover to show whether the oil level in the oil tank is normal. The top of the YW series tubular oil level indicator is equipped with a pressure release valve. When the pressure in the oil tank rises to the opening pressure of the release valve, The release valve opens quickly to release pressure and prevent danger. [0003] However, the oil-immersed fully sealed transformer winding has a high failure rate, and ...
