First, the gas protection: to protect the transformer internal short circuit and oil surface failure.Second, differential protection, current quick-break protection: to protect the oil immersed power transformer winding or lead-out phase of the phase short circuit, large ground current system grounding short circuit and winding turn short circuit.T... First, the gas protection: to protect the transformer internal short circuit and oil surface failure.Second, differential protection, current quick-break protection: to protect the oil immersed power transformer winding or lead-out phase of the phase short circuit, large ground current system grounding short circuit and winding turn short circuit.Third, over-current protection: to protect the external phase short circuit, and as a gas protection and differential protection (or current quick-break protection) backup protection.Four, zero sequence current protection: protection of large ground current system external single-phase ground short circuit.Five, overload protection: to protect the symmetrical overload, only acting on the signal.Six, over-excitation protection: to protect the transformer over-excitation does not exceed the allowable limit.Gas protectionReaction transformer tank internal failure and oil surface reduction .0.8MVA and above oil-immersed transformers and 0.4MVA and above the plant oil-immersed transformers, should be installed gas protection. When the tank failure to produce a slight gas or oil drop, should be instantaneous action on the signal; when generating a lot of gas, should be turned off the transformer on each side of the circuit breaker. With the pressure regulator of the oil-immersed transformer pressure regulator, should also be equipped with gas protection.Pilot differential protection or current quick-break protectionResponse transformer lead wire, casing and internal short-circuit fault of the vertical differential protection or current quick-break protection. Protection of the momentary action in the disconnect the transformer on both sides of the circuit breaker.1. For 6.3MVA following plant transformer and parallel operation of the transformer, and 10MVA following plant backup transformer and a separate operation of the transformer, when the backup protection time is greater than 0.5s, should be installed electric speed quick protection.2. For 6.3MVA and above work transformer and parallel operation of the transformer, 10MVA and above plant with transformers and separate operation of the transformer, and 2MVA and above with the current speed protection protection does not meet the requirements of the transformer, should be installed Joint differential protection.On the high side voltage of 330kV and above the transformer, can be installed double vertical differential protection.When there is no circuit breaker between the generator and the transformer, there is a circuit breaker between the generator and the transformer, and the generator device alone is protected by differential protection. When there is no circuit breaker between the generator and the transformer, 100MVA and below the generator and the transformer group shared with the differential protection; 100MVA above generator in addition to the generator transformer common differential protection, the generator should also be a separate device longitudinal Joint differential protection. For the 200 ~ 300MVA generator transformer group can also be added in the transformer vertical differential protection, that is, the use of double fast protection. View Details

Electrical Power Transformer, Distribution Transformer and Instrument Transformer - Power transformers are generally used in transmission network for stepping up or down the voltage level. It operates mainly during high or peak loads and has maximum efficiency at or near full load. Distribution transformer steps down the voltage for distribution purpose to domestic or commercial users. It has good voltage regulation and operates 24 hrs a day with maximum efficiency at 50% of full load.  View Details
