1 这种TBP过电压保护器是有间隙的氧化锌避雷器一类，因间隙的存在，则不论是正常运行还是单相接地故障，只要过电压不超过TBP过电压保护器的动作电压，TBP过电压保护器里是不流过电流的，这时它是荷电率为零，延缓了元件的老化问题，提高了可靠性。
1 the TBP overvoltage protector is a kind of Zinc Oxide gap arrester, due to the gap exists, whether the normal operation or single-phase ground fault, as long as the voltage does not exceed TBP voltage voltage protector, TBP overvoltage protector is not current, then it is charged the rate of zero, delaying the aging problem of components, improve reliability.
2 因间隙的存在，故U1mA可以做得很低，10KV过电压保护器 U1mA=16.5KV、6KV U1mA=10.5KV。所以TBP过电压保护器的操作冲击残压值远低于同类产品在相同冲击电流下的残压值。
2 because of the gap, U1mA can be done very low, 10KV over-voltage protector U1mA=16.5KV, 6KV U1mA=10.5KV. Therefore, the operation residual voltage of the TBP overvoltage protector is much lower than that of the same product under the same impact current.
3 由于特殊结构，可将相间过电压大大降低，与常规氧化锌避雷器相对，相与相之间过电压下降了至少60~70%，可靠地保护了被保护的电气设备。
3 because of the special structure, the phase crossing overvoltage can be greatly reduced, relative to the conventional Zinc Oxide arrester, the overvoltage between phase and phase is decreased by at least 60~70%, and the protected electric equipment is reliably protected.
