High voltage AC SF6 tank circuit breaker

Product Introduction

□ LW36-72.5THigh voltage AC SF6 tank circuit breakerThe circuit breaker and current transformer are centralized together, and the arc extinguishing chamber is horizontally installed in a grounded aluminum alloy shell, equipped with a CT26 type spring operating mechanism. It uses fewer components, has a simple and compact layout, and is sturdy and durable as a whole, meeting the requirements of oil-free switches. It has excellent mechanical characteristics and high reliability. All important components are processed by CNC and machining center equipment, and the bearings are imported international brand bearings (such as IKO, INA, SKF, etc.), with a mechanical life of up to 10000 times. Suitable for outdoor high-voltage switchgear with three-phase AC 50Hz, it can be used for control and protection of 72.5 (126) kV transmission and transformation systems; It can also be used for connecting circuit breakers and opening and closing capacitor banks

structural characteristics

High performance - Strong rated current capacity: 3150A, large short-circuit breaking capacity at 40 ℃: 31.5kA.

□ High lifespan electric lifespan: 31.5kA x 24 times (25kA x 31 times), mechanical lifespan: can reach 10000 times after simple adjustment.

The high reliability arc extinguishing chamber structure is shared with LW36-126, with a large insulation margin inside the product, a spring mechanism, a simple structure, high reliability, and is used for frequent operation.

The breaking performance is reliable.

Reliable sealing, SF6 annual leakage rate<0.5%.

□ Meet the requirements of harsh operating environments, suitable for Class IV polluted areas and environments ranging from -40 ℃ to 40 ℃.
