LW36 SF6 Circuit Breaker,
66K SF6 Circuit Breaker,
145kv SF6 Circuit Breaker
1. LW36 66 Kv - 145kv Live Tank Type Outdoor Gas Sf6 Circuit Breaker
Circuit breakers meet the requirements specified in EN 62271-1, EN 62271-100, EN 60273, and other relevant EN (IEC) standards.
Circuit breakers is a "live-tank" type, for external installation, with SF6 gas for insulation and a medium for extinguishing the arc.The driving mechanism is motor-spring. In order to maintain the stability of the system and reduce electrical, mechanical and thermal stress, the working times for switching off of the fault currents is as short as possible.
Apart from switching off short-circuit currents, the circuit breaker is able to perform other operations such as disconnecting the capacitors, transformers and power lines.
2. Technical Description
Circuit breakers use the "SF6 single-pressure" method to extinguish the arc.
The circuit breaker mechanically dimensioned to the short-circuit loads and tensile strengths of IX-level earthquakes by EMSC-98. The high voltage connections are made of aluminum with screw holes according to IEC standards.
The circuit breakers are designed for single-pole and three-pole quick re-start. The drive mechanism has the option of automatic re-start (APV) with cycle O -0.3 s - CO - 3 min - CO.
The circuit breakers are equipped with a temperature-compensated density gauge for indication of the gas pressure.
