Normal working terms 1.Environmental temperature: -40aa ~ +60aa;Rated frequency: 48Hz~ 62Hz 2.Altitude:< 2000m
Character
1. Maximum capacity, better limite voltage effect, more widely applicable scope, stronger tolerance , long lifespan
2. Voltage impact coefficient is 1, under the various kinds of electric voltage waveform, the voltage values are equal
3. With zinc oxide nonlinear resistors and discharge gap between the structure, make the two are complementary protected. The spark gap make the State-of-Charge of zinc oxide resistance to zero, Zinc oxide resistance nonlinear characteristics also make the spark gap action without free-wheeling in future, The spark gap no longer bear arcing tasks, and improve the service life of the product;
4. Four lines connect method, can be greatly reduce the voltage of phase, the reliability of the protection is greatly improved;
5. Valve plates and the spark gap assemble space, and mutual influence, discharge electrode is not easy to damp, be oxidated, make action value more stable and reliable.
6.Take overvoltage action techniques and fault automatically function , realize the device maintenance free, at the same time, to avoid the tedious work periodically, to solve the engineering and technical personnel to worry about the problems of the equipment safe running .
High-energy explosion-proof type composite over-voltage protector
