LW36-126T3150-40

High-volt  ac  Sf6  dead  tank circuit   breaker

□Meaning of type

□Introduction

□LW36-126T high-voltage AC SF6 tank circuit breakers and current transfrmer circuit breaker will be together,and interrupters mounted horizontally in the grounded aluminum alloy housing,equipped with a CT26 spring operating mechanism,which  The  parts used are few,the layout is simple and compact,the whole is solid and durable,the switch is oil-free,the mechanical characteristics are excellent and the reliability is high.All the important parts adopt the CNC machining and machining center equipment processing. The bearings adopt imported international brand bearings,INA,SKF and other brands),mechanical life up to 10,000 timesIt can be used for control and protection of 72.5(126)kV power transmission and distribution system.It can also be used in contact open circuit and opening and closing capacitor banks.

口 Characteristic 

□The broaker introduces the three-phase porcelain-pole with single interrupter structure.Aspring operating mechanism is supplied and the mechanical actlon of the three-phase Is Inner connected.The gas of the SF6Is connected In the three-phase pole parts.A denslty controller wlth temperature  compensatlon Is used to monltor the gas of the SF6.Because of the self-extInctlon arc control prlnclple and optImlzed deslgn,It Improves the efflclency of mechanlsm and reduces the operatlng power.

□Excellent breaking performance and long electrical life.

□The metal frame and the support of the circuit breaker are bended with a whole deep steel plate.The hot galvanizing is used for the surface treatments.  The high strength stainless steel and aluminum are used for the fasteners and the three-phase transmission shaft respectively.The surface ofstructure box is made by stainless steel;the corrosion resistance of the mechanism is improved efficiently.

□High mechanism reliability and can be operated frequently.

□Because of the high insulation intensity and excellent contact movement,the breaking capacity current will not re-burn.

□T he circuit breaker has high outer insulation level and ratio creepage distance is greater than 31mm/kV.So it has excellent performance of resisting the filth and the earthquake,it is also can be operated safely under the environment with atrocious weather.

□High carrying ability:ithas high capability margin as the temperature of each contact rises when it is under temperature rise test in the circuit of 3780A (1.2 times of3150A).

□The appearance of the breaker is compact,and the installation and debugging is very easy.The maintenance is also very convenient.
