Product Description

Reliable 72.5kv Two Phase Circuit Breaker for Outdoor Use
LW36-55 OUTDOOR HIGH VOLTAGE SULFURHEXAFLUORIDE CIRCUIT BREAKER
Introducing the innovative LW Series Self-Energy SF6 Circuit Breaker, a state-of-the-art three-pole/single-pole AC 50Hz/60Hz outdoor high voltage marvel designed to seamlessly manage power transmission. Engineered for precise division of rated and fault currents, as well as conversion lines, this circuit breaker is your ultimate solution for transmission and distribution system protection, control, and operation. Experience unmatched versatility with its ability to perform opening, closing, and rapid automatic reclosing operations.
Our circuit breaker employs cutting-edge design principles, showcasing a streamlined structure, compact form, and minimal resource requirements. With high reliability and effortless installation, it operates with minimal energy, all while maintaining low noise levels. Introduced as a new generation of high voltage SF6 circuit breakers, this product embodies our company's commitment to excellence.
Service Environment
. Ideal ambient temperature range: -40 ºC to +50 ºC.
. Daily average ambient air relative humidity: ≤ 95%, with an overall average of ≤ 90%.
. Wind pressure: Below 700 Pa.
. Altitude suitability: Less than 3000 meters. . Earthquake resistance: Up to 9 degrees.
. Air contamination level: Standard grade.
Operation Mechanism: Upon closure of the circuit breaker, both the closing and opening springs are energized. The internal and external crutch arms bear the contra-clockwise moment, and once the opening winding is activated, the lock releases. This contra-clockwise rotation is driven by the open spring, enabling the inside crutch arm to open the circuit breaker. The mechanism retains its state by keeping the engine in an open position.
In the spring mechanism's open state, the close spring is primed for energy storage. The ratchet wheel axis absorbs the moment from the opening spring in a contra-clockwise direction. The moment is held steady by the engine, awaiting the opening winding's activation. Once engaged, the cam and ratchet wheel work in harmony, releasing the energy stored by the closing spring to depress the open spring and open the circuit breaker. When closing is complete, the close spring releases, as depicted in Figure 1, and the pawl axis engages with the motor through gearing, promptly recharging the open spring.
