Detailed Product Description: | Voltage transformer divided by the number of phases: the vast majority of the product is a single-phase voltage transformer because of the small capacity, the plot is not the body, both inside and outside the three-phase high-voltage bushing insulation requirements between the high voltage transformer Hengshui difficult to meet, so only 3 -15kV products sometimes using three-phase structure. Transformer burned reasons: 1, between the low side voltage transformer turns and when phase short circuit, low insurance has not been blown, the magnetizing current increases rapidly due to high voltage transformers Langfang, high pressure pipe fuse is blown fuse or burn out transformers. 2, when the single-phase ground outlet 10kV high pressure transformer, voltage transformer primary side voltage is relatively non-fault root of 3 times the normal voltage. Voltage transformer core saturation quickly Changzhou high pressure transformer magnetizing current sharply increased, so that the fuse is blown. 3, since the capacitive and inductive elements of the power network parameters contained, in particular the inductance element with the ferromagnetic core, the magnetic resonance caused by unfavorable parameter combination. 4, zero-sequence current flowing through the transformer primary winding voltage increases (in terms of excessive relative to the ground current system), long-running, the thermal effect generated by the zero-sequence transformer will cause damage to the insulation voltage transformer, burst ; nonlinear oscillations (arc grounding overvoltage), greatly exacerbated the damage process system voltage transformer 5, the existence of the system; 6, voltage transformer itself is poor cooling conditions. Beijing high-voltage transformer | Huayi Electric Power (certified) | high voltage transformer provided by the Xi'an Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future. |
