VS1-40.5KV/T Type Indoor High Voltage 35kV Vacuum Circuit Breaker For KYN61 Switchgear
General Description:
VS1-40.5/T type indoor high voltage vacuum circuit breaker is used for switchgear KYN61-40.5(Z). Mainly used in rated voltage 40.5kV, three-phase AC 50Hz power system, can be used for protection and control of industrial and mining enterprises, power plants and substations, especially suitable for various frequent operation places. It’ s the most new type of power supply and distribution equipment.
This product meets the standard requirements of GB11022 “High-voltage switchgear and control equipment standard common technical requirements”, GB1984 “AC high-voltage circuit breaker” and IEC56 “High-voltage AC circuit breaker” and other standards
Applying ambient Conditions:
1. Ambient temperature: -15℃一+40℃, the average temperature is not more than 35℃ in 24 hours
2. Height above sea level：≤1000m;
3. Relative humidity: the average humidity of a day should be no more than 95%; the average humidity of a month should be no more than 90%;
4. Saturated vapor pressure: the average pressure of a day should be no more than 2. 2kPa, the average humidity of a month should be no more than l.8kPa;
5. Environmental conditions: It should be installed in the places without dust, smoke, chemical erosion, combustible gas and saline fume pollution.Structure Characteristic:
This kind of VCB adopt integrated design and is different from open-type vacuum circuit breaker and insulation vacuum circuit breaker.
1.The vacuum interrupter and conductive circuit fitting with ring raises resin through the special craft are sealed into a pole.
2.Then with the modularized circuit assembled in modular circuit breaker.
3.This kind of VCB with excellent electrical&mechanical properties the advanced level of the vacuum circuit breaker in the modern world.Technical Characteristics:
The design of this kind of VS1-40.5/T takes into account the Chinese market and special areas requirements, making the vacuum interrupter and conductive circuits into a embedded pole by the advantage of the solid insulation and advanced technology of APG.
This not only simplifies the pole assembly process and prevent the vacuum interrupter circuit conductive connecting bolt to run the VS1 ration as a result of loose, but also improve reliability and avoid the effect of external mechanical force and ambient conditions (such as dust, humidity, nasty, high sea level, animal), and avoid the potential risk of vacuum interrupter operating in adverse environments caused by insulation and then lead to a lower level of vacuum circuit breaker in the sub-gate under vacuum interrupter surface elastomer. Therefore, within the service life of the circuit breaker, the pole is completely maintenance-free. The circuit breaker’s solid insulation replace SF6 to meet the need for external insulation. It’ s more environmental protection and represents the advanced level of the vacuum circuit breaker in the modern world. -
