Brief Description
LW35 serial circuit breakers, including LW35-72.5, LW35-126, LW35-145 and LW35-252 products, are designed with self-energizing principle that arc generated in the interrupter is distinguished at a specified time with a part of energy produced by the arc itself. They are used for making and breaking normal current, fault current and switching lines to realize the operation (three-pole opening&closing operation and fast automatic-reclosing operation), control and protection of power system.
Main Features
1 Less consumption of SF6 gas, benefitial for environmental protection. When other kinds of circuit breaker at 0.6 MPa must be filled with SF6 of 27 kg/set, this kind of circuit breaker only need 19.3 kg/set.
2 Dynamic sealing system adopts advanced Glyd ring and Step seal to reduce starting friction and prevent leakage.
3 Adopt imported control valve of stable performance and anti-slow-opening function in case of pressure loss.
4 Two sets of independent opening control circuit are adopted in hydraulic mechanism with two sets of relay protection to enhance service reliability.
