Buchholz Relay Working Principle In Hindi

It is a mechanical device that accompanies two numbers of mercury electric switches for sending the electrical command to the relays.

Buchholz relay working principle in hindi. Buchholz relay is a safety device which is generally used in large oil immersed transformers rated more than 500 kva. Buchholz relay diagram working principle. In large oil immersed transformers we can find a cylindrical object installed in the pipe connecting the conservator to the main tank. Buchholz relay working principle construction and operation.

Buchholz relay क उपय ग transformer winding और core म ह न व ल faults क महस स करन क ल ए क य ज त ह ज स क inter turn faults short circuits earth faults overheating of the core oil leakage आद यह इन faults क. If an internal fault occurs of the transformer the. It is mechanically actuated. The transformer is filled with hydrocarbon oil for the insulation of winding and cooling of the transformer.

It is used for the protection of a transformer from the faults occurring inside the transformer such as impulse breakdown of the insulating oil working principle of buchholz relay whenever a fault occurs inside the. The operation of the buchholz relay is based upon the fact that every kind of fault in an oil filled transformer causes a decomposition of the insulating oil due to overheating in the fault zone or to the action of an intense electric field and a generation of bubble of gas. Buchholz relay relies on the fact that an electrical fault inside the transformer tank is accompanied by the generation of gas and if the fault is high enough it will be accompanied by a surge of oil from the tank to the conservator. The buchholz relay working principle of is very simple.

A generic designation for this type of device is gas. You can learn more about. Whenever there will be a minor internal fault in the transformer such as an insulation fault between turns break down of core of the transformer core heating the insulating transformer. These reach the relay which is normally filled with oil through the pipe.

Buchholz relay function is based on very simple mechanical phenomenon. This cylindrical object that looks like a solenoid valve is called buchholz relay. It is a type of oil and gas actuated protection relay. A simple explanation of a buchholz relay.

The buchholz relay is used as a protective device sensitive to the effects of dielectric failure inside the equipment.
