Self-couple Boost DC/DC Conversion;

自耦式Boost DC/DC变换

A novel self-coupled compensated and shielding harmonic converter transformer is proposed,its structure has advantage of self-coupled function of transformer and originates moving the reactive compensation equipment to the inner windings,which will greatly decrease the voltage scale of reactive compensation equipment.

针对城轨交通供电系统的传统换流站产生的谐波和无功功率由变压器绕组注入交流网侧,既增大变压器制造成本,又产生噪音问题,提出了一种具有内部三角形绕组的自耦补偿与谐波屏蔽换流变压器,它将传统无功补偿装置移至绕组内部且公共绕组的等效短路阻抗为零阻抗设计,使二次侧各种谐波源无法进入高压网络,有效抑制了供电系统中的谐波成分,从而具备自耦补偿和谐波屏蔽功能。

The new converter transformer is provided with self-coupled compensated and shielding harmonic by displacing the compensated equipment to the inner windings for shielding the harmonic in both sides of the converter transformer windings efficiently.

提出了一种新型换流变压器的设计方案,将无功补偿装置移至换流变压器绕组内部,使其自身具备了自耦补偿和谐波屏蔽的功能,有效地对换流变压器的原副边绕组进行滤波,从而克服了无功功率和谐波给变压器带来的绕组和铁心中增大附加发热和噪音与振动问题,大大降低了换流变压器的负载损耗。

To enhance the sensitivity of ground fault proteftion,330 kV and its above EHV large capacity autotransformers are equipped with aero-sequence current differential protection.

330 kV及以上超高压大容量自耦变压器常配有零序电流差动保护,以提高接地故障时保护动作的灵敏性。
