40.5kV 72.5kV 145 kV 252kV Serie ng Dead Tank circuit breaker

Product introduction：

Ang LW58A-40.5/72.5/145/252 Dead Tank circuit breaker usa usa ka bag-o nga henerasyon sa maopay nga high-voltage electrical equipment nga gipatun-an pinaagi sa independent development, ang tank type circuit breaker gisangpotan sa entrance bushing, lead-out bushing, CT, arc extinguishing chamber, chassis, operating mechanism, ug uban pa. Kini mahimong gamiton sa high-cold ug high-altitude area, karon ang bag-o nga henerasyon sa tank type LW58A-40.5/72.5 products nakaabot na sa leading domestic ug international advanced level sa advanced technology ug quality reliability.

Main characteristic：

•  Maayo nga anti-seismic performance, ang produktu masama sa seismic grade sa GlS.

  （a）Horizontal arrangement sa arc extinguishing chamber, low center of gravity.

  （b）Auto seismic frequency: Ang porcelain column breaker mga 4.5 Hz, ug ang tank circuit breaker mga 13.5 Hz.

• Ang electric tracing band solution mahimong gamiton sa high-cold region, kini wala mahimo sa porcelain column circuit breaker.

• Ang produktu mahimong gamiton sa 5000m nga area, ang standard configuration sa arc extinguishing chamber & drive system mahimo ra isip fixed sa height sa outlet casing.

•  Ang tank type circuit breakers nagintegre sa straight through current transformer, ang produktu may menor nga coverage sa area, stable nga kalidad, ug menor nga on-site maintenance work. Samtang niini, nasolbaron ang problema sama sa small margin sa CT insulation, limitation sa CT capacity, ug high cost, aging, cracking, ug explosion sa CT.

•  Design sa arc extinguishing chamber：Horizontal Structure, gi-adaptar ang thermal expansion ug auxiliary pressure gas extinguishing technology, may menor nga operation work, excellent breaking performance, ug more than 20 electrical life.

• Environment adaptability:Suitable sa severe environment conditions (such as severe pollution, water fog, hall, etc.), high - altitude area, earthquake area, ang box body sealed sa air bag type, ug ang body protection grade IP66.

• Ang CT sa variable ratio ug multi-level combination mahimong gisangpot, may mataas nga accuracy, easy to add capacity, ug meet 80% o the operating frequency voltage under the value of 5Pc, mahimong configured sa TPY.

•  Complete CT protection measures: Ang CT shell sealed sa both ends sa shell ug special anti-condensation design.

• Ang light spring operating mechanism nagamit ang overall cast aluminum frame. Breaking spring, closing spring, ug buffer centralized arrangement, ug tanan spiral double pressure spring, compact structure, dili easy to fatigue.

• Ang produktu menor, integrated design, integrated supply, integrated installation conditions.

• May breaking capacity sa 4000A back-to-back capacitor bank.

What are the structural characteristics of the tank circuit breaker？

Integral Tank Structure：

• Integral Tank Structure: Ang breaker's arc quenching chamber, insulating medium, ug related components sealed sa metal tank filled sa insulating gas (such as sulfur hexafluoride) o insulating oil. This forms a relatively independent ug sealed space, effectively preventing external environmental factors from affecting the internal components. This design enhances the insulation performance ug reliability of the equipment, making it suitable for various harsh outdoor environments.

Arc Quenching Chamber Layout：

• Arc Quenching Chamber Layout: Ang arc quenching chamber typical installed inside the tank. Its structure designed to be compact, enabling efficient arc quenching within a limited space. Depending on different arc quenching principles ug technologies, the specific construction of the arc quenching chamber may vary, but generally includes key components such as contacts, nozzles, ug insulating materials. These components work together to ensure that the arc is quickly ug effectively extinguished when the breaker interrupts the current.

Operating Mechanism：

• Operating Mechanism: Common operating mechanisms include spring-operated mechanisms ug hydraulic-operated mechanisms.

• Spring-Operated Mechanism: This type of mechanism simple in structure, highly reliable, ug easy to maintain. It drives the opening ug closing operations of the breaker through the energy storage ug release of springs.

• Hydraulic-Operated Mechanism: This mechanism offers advantages such as high output power ug smooth operation, making it suitable for high-voltage ug high-current class breakers.
