According to the high saturation flux density anti-resonance voltage transformer, the annual iron core is adopted, the defect of the air gap magnetic hysteresis loss caused by a traditional laminated core is overcome, the saturation flux density is improved, meanwhile, the transformer body is put into an oil tank filled with transformer oil, the insulating strength is enhanced, and the cracking phenomenon generated in the transformer pouring process is eliminated.
Description
Technical field
The utility model relates to a kind of high saturation magnetic induction anti-resonance potential transformer, belongs to high-tension fields of measurement.
Background technology
The domestic 35kV oil immersed type electromagnetic potential transformer for electric power system is due to the reason of its design aspect at present, substantially there is saturation characteristics in excitation property under 1.2 times～1.5 times rated voltages, do not meet state's net countermeasure: system with non effectively earth ed neutral, voltage transformer excitation property requires saturation point to reach 1.9 times.Although and cast voltage transformer excitation property saturation point can reach 1.9 times, because the characteristic of expanding with heat and contract with cold of its material is poorer than insulating oil, in use there is material cracking phenomena in many cast voltage transformers therefore, causes breaking down.
Utility model content
Technical problem to be solved in the utility model, a kind of high saturation magnetic induction anti-resonance potential transformer is proposed exactly, the saturation magnetic induction of this voltage transformer can reach 1.9 times of state's net countermeasure, and there is higher saturation magnetic induction, can effectively prevent that resonance from producing, can overcome the defect of cast voltage transformer cracking simultaneously.
For solving the problems of the technologies described above, technology of the present utility model by the following technical solutions:
A high saturation magnetic induction anti-resonance potential transformer, comprises iron core and around high pressure winding and low pressure winding on described iron core, described iron core is annular core.
When further, described high saturation magnetic induction anti-resonance potential transformer is worked, be arranged in the fuel tank that fills transformer oil.
Compared with prior art, the beneficial effect the utlity model has is: the utility model is by selecting annular core, can effectively overcome the air gap magnetic hysteresis loss that traditional laminated core air gap causes, improve saturation magnetic induction, this device body is put into the fuel tank that fills with transformer oil simultaneously, improve dielectric strength, stop the cracking phenomena of casting transformer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
In figure: 1-iron core; 2-high pressure winding; 3-low pressure winding.
Embodiment
For allowing the more clear and intuitive understanding the utility model of those skilled in the art, below in conjunction with accompanying drawing, the utility model is further described.
If Fig. 1 is preferred embodiment of the present utility model.
A high saturation magnetic induction anti-resonance potential transformer, comprises annular core 1 and around high pressure winding 2 and low pressure winding 3 on iron core 1.
In embodiment by selecting annular core, can effectively overcome the air gap magnetic hysteresis loss that traditional laminated core air gap causes, improve saturation magnetic induction, the high saturation magnetic induction anti-resonance potential transformer of the present embodiment is arranged in the fuel tank that fills with transformer oil when work, can improve dielectric strength, stop the cracking phenomena of casting transformer.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
