9、re of combined zinc oxide non-linear resistance and discharge gap to protect each other. The discharge gap makes the chargeability of zinc oxide resistance to be zero, the nonlinearity of zinc oxide in turn makes it extinguish arc after the discharge gap acts without continuous flow and cutoff, and
10、the discharge gap no longer undertakes the extinguishing task, thus improves the service life of product.2. Under a variety of voltage waveforms, all the discharge values are equal, which are not affected by various operating overvoltage waveforms, the protection value of overvoltage is correct and
11、the protection performance is excellent.3. It adopts four-star connection, which can limit both overvoltages between phases and phase to ground. It can greatly reduce the overvoltage between phases, compared to the conventional arrester, the overvoltage between phases is reduced significantly, there
12、fore, the reliability of protection is greatly improved. 4. It adopts silicon rubber casing and high voltage cable leading-out structure with the advantages of easy to install, good sealing, small volume, vibration resistance etc. It can be directly installed on the hand bogie underpan of switchgear
