Product Group : T06

Buchholz relay is assembled between both the pipe lines connected to transformer tank and conservator, respectively and is one of the apparatuses of transformer which makes an alarm signal when the quantity of air bubble is more than a setting value and also makes a trip signal when the oil level is lower than 50% of the oil level of inside the relay.

The relay is one of the apparatuses to prevent efficiently the proceed and enlargement of transformer accident by means of making a trip signal when the velocity of insulation oil in the pipe line is faster than a setting value. If a fault occur inside the transformer, some dissolved gas is generally happened inside the transformer.

In case of a negligible fault, the gas is very slowly produced in the oil in bubble form and the bubbles are finally accumulated in the relay after being first gathered at the upper part of inside the tank.

In case of a serious fault, the insulation oil will quickly flow into conservator or other escape space because of a rapid increase in oil volume.

When gas is very slowly produced in the oil in bubble form, the relay makes an alarm signal and when the insulation oil will quickly flow inside the pipe lines, the relay makes a trip signal.

TAIJIN’s Buchholz relays are classified into 2" Buchholz relay and 3" Buchholz relay in accordance with the hole diameter of the relay connected to pipe lines and widely used for high voltage class transformers because the relay is characteristic of a solid construction, a stylish shape, and a high reliability.
