Product Introduction

/filedownload/50488ZW20 Series Vacuum circuit breaker consists of three parts: circuit breaker body, operating mechanism and lifting device.The circuit breaker body consists of conductive circuit, insulation system, the seals and housing. The entire conductive loop is formed by in and out wire conducting rod, conductive clip, soft connection and vacuum arcing chamber.

This product uses SF6 gas insulation. The inlet and outlet insulating sleeves are integrally cast with epoxy resin silicon rubber. In order to reduce the volume of the switch, A and C phases use a corner bushing to ensure good external insulation. The interior adopts a composite insulation structure, in the case of no SF6 gas charging, it also can reach the corresponding insulation level.

This product adopts a mature sealing structure: the mechanism cover and the upper cover of the housing are sealed with a stamping forming groove, and the output pointer shaft is sealed with a double 0” ring, and the inlet and outlet line bushings are integrally cast to ensure good airtightness.

Normal service condition:

1. Altitude≤2000

2. Ambient temperature: -15℃~+50℃

3. Maximum water vapor pressure:24 hours ≤2.2kpa1 month ≤1.8kpa

4. Wind pressure:≤700pa(34m/s)

5. Earthquake intensity ≤8

6. Ice thickness ≤10mm

7. No fire, explosion danger, chemical corrosion, violent vibration
