General:
LW30-550(T)/Y5000-63 high voltage SF6 tank-type circuit breaker is invented by our company so as to satisfy the demand of extra-high voltage(EHV) distribution device’s high parameter, high reliability, easy running. The circuit breaker
be superior to domestic like products. It is the first choice of 550KV power system;
The main characteristics:
Good breaking capacity to fault.
The circuit breaker uses the principle of self arc-extinguish. The spout is designed by simulated analysis. It has the excellent performance of arc-extinguish. The short-circuit breaking current is 63KA, and the arcing time is short. The operation noise is small.
Long electrical life
The arc-extinguish chamber owns lots of patent technology. The spout and arc contact uses new arc resistant material. The main contact uses new structure,and the insulation tank between fractures uses new process. Free-maintenance in the condition of continues breaking 63KA short circuit current 20 times.
l The high insulation level
The arc-extinguish chamber is optimally designed by Ansys.
It owns lots of patent. The furnace of electrode uses electrostatic coating technology. The insulation level has reached the highest standard of GB1984 and IEC62271.
Great peak current
The contact of main conductive loop uses new Copper alloy materials and spiral spring contact and so on with small volume, good conductive performance, high dynamic reliability. It can run with 5000A current.
High mechanical reliability
The circuit breaker is equipped with ABB HMB-8 spring operation structure with high reliable operation. Free-maintenance in the condition of continues 10000 times operation.
The main structure:
Arc-extinguish chamber
It is designed according to auto arc-extinguish principle.
Circuit breaker
It is designed to horizontal type and double fracture structure. It is equipped with HMB-8.3 spring operation system.
