Product Description

Liugao is a outdoor vacuum circuit breaker supplier.Our outdoor vacuum circuit breaker are widely used in the 10kV, 13kV city, rural power grid space ring network for disconnecting switches, contact switches, and automatic switch devices, which can implement the ring deployment line load. It can be used as a boundary switch (commonly known as watchdog) in the branch line of power supply, used as reclosers and sectionalizers in feed overhead distribution networks. The outdoor vacuum circuit breaker comes with remote management patterns, protection and control functions, and communication capabilities. It provides reliable detection and judgment, mA-level zero sequence current sensing, and short-circuit current between phases, realizing the automatic removal of single-phase grounding faults and phase-to-phase short-circuit faults. The main switch is a vacuum arc, and the insulation adopts SF6, N2 mixed gas. The case introduces Japan, Germany, French gas sealing, explosion-proof, insulation system technology, ensuring overall excellent sealing performance. Inside, it is filled with SF6, N2 mixed gas, which does not leak and is not affected by the external environment. The spring operating mechanism, with miniaturization and performance optimization design, enhances action reliability well beyond traditional spring mechanisms.

Outdoor Column High Voltage Electric Vacuum Circuit Breaker Operating Environment

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.

2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.

3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.

4. Installation gradient not exceed 5.

5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.

6. Any specific requirement, consult with manufactory.
