三相组合式过电压保护器过电压保护器与传统的避雷器以及其它同类产品相比，有不可比拟的特点：

Three-phase modular overvoltage protectors over-voltage protector compared with the traditional lightning arrester, and other similar products, has incomparable features:

1.采用氧化锌非线性电阻和放电间隙串联的结构，使两者互为保护;放电间隙使氧化锌非线性电阻的荷电率为零，氧化锌的非线性特性又使放电间隙动作后立即熄弧，无续流、无截波，放电间隙不再承担灭弧任务，提高了产品的使用寿命，在操作过电压下，动作寿命可达105次;

1. Using zinc oxide non-linear resistance and structure of discharge gap in series, make each other protection; Discharge gap makes the chargeability of zinc oxide non-linear resistance is zero, the nonlinear characteristics of the zinc oxide and the discharge gap action immediately after arc, stream, cut wave, discharge gap is no longer bear the arcing tasks, improve the service life of the product, under the operating overvoltage, movement life can reach 105 times;

2.电压冲击系数为1，在各种电压波形下，放电值均相等，不受操作过电压类型影响，过电压保护值准确，保护性能优良;

Impact coefficient is 1, 2. Voltage under various voltage waveform, the discharge values are equal, not influenced by operating over-voltage types, over voltage protection value accurately, protect the good performance;

3.采用四星形接法，可将相间过电压大大降低，与常规避雷器相比，相间过电压降低了60～70%，保护的可靠性大为提高;

3. The four star connection, and overvoltage can be greatly reduced, compared with the conventional lightning arrester, and overvoltage reduced 60 ~ 70%, the reliability of protection greatly improved;

4.采用硅橡胶外套和高压电缆外引结构的过电压保护器，除具有瓷绝缘外套的电气性能外，还具有易安装、密封性强、体积小、耐震(振)动等优点，可直接安装在开关柜的手车底盘上或互感器室内;

4. Adopt silicon rubber coat and over-voltage protector of irfpa high voltage cable structure, except with the electrical properties of porcelain insulation coat also has easy installation, strong sealing, small volume, and the advantages of seismic dynamic (vibration), can be directly installed in handcart switch cabinet chassis or transformer indoor;

5.使用环境温度为-40℃～+60℃，海拔高度小于2000m，(高于2000m，在订货时请注明);

5. Using the environment temperature of 40 ℃ ~ + 60 ℃, less than 2000 m altitude, (above 2000 m, please specify when ordering).

6.在系统发生间歇性弧光接地过电压及铁磁谐振过电压，若其能量小于2ms.400A方波冲击能量时，过电压保护器可以起到保护作用。

6. In the system of intermittent arc grounding over voltage and ferro-resonance over voltage, if the energy is less than 2 ms. 400 a square wave impact energy, the over-voltage protector can protect.
