Transformer simulation system and setting value simulation measurement method

Abstract

The invention discloses a transformer simulation system and a setting value simulation measurement method. The transformer simulation system comprises an oil box, a heating device, a pump body, a first oil pipe, a second oil pipe and a first flow sensor, wherein the heating device is arranged in the oil pipe, a first inlet and a first outlet are arranged in the oil box, the first outlet communicates with the first oil pipe, the first inlet communicates with the second oil pipe, one end, far away from the oil box, of the first oil pipe is a first installation end for communicating with an oil inlet of a gas relay, one end, far away from the oil box, of the second oil pipe is a second installation end for communicating an oil outlet of the gas relay, the pump body communicates with the firstoil pipe or the second oil pipe, and the first flow sensor is arranged in the first oil pipe. An oil flowing speed, namely a setting value of the gas relay, can be measured by the transformer simulation system, types of insulation oil can be replaced, the corresponding setting value of the gas relay is obtained, and the situation that an original gas relay cannot have a protection effect caused by different properties of the insulation oil is prevented.

Description

technical field [0001] The invention relates to power grid test equipment, in particular to a transformer simulation system and a setting value simulation measurement method. Background technique [0002] Heavy gas protection is the main protection for internal faults of the transformer. When an internal fault occurs in an oil-immersed transformer, the arc decomposes the insulating material and generates a large amount of gas, which flows from the oil tank through the gas relay to the oil conservator. When the oil flow speed reaches the set value When the value is set, the heavy gas will start the protection action. [0003] Traditional oil-immersed transformers use mineral insulating oil as the insulating liquid. With the development of transformers, the types of insulating liquids are also developing in the direction of environmental protection and cleanliness. When an oil-immersed transformer using a new type of insulating liquid fails, the oil flow rate will change. If ...

[0003] Traditional oil-immersed transformers use mineral insulating oil as the insulating liquid. With the development of transformers, the types of insulating liquids are also developing in the direction of environmental protection and cleanliness. When an oil-immersed transformer using a new type of insulating liquid fails, the oil flow rate will change. If the setting value still refers to the previous value, the transformer will not be able to perform heavy gas protection in time, causing equipment damage and potential safety hazards.
