VS1-12 Indoor high voltage trolley type vacuum circuit breaker
Operating Environment
The VS1-12 series indoor high voltage trolley type vacuum circuit breaker is designed for indoor environments and can operate reliably across a wide temperature range from -10ºC to 40ºC. It is suitable for areas with an altitude of up to 1000 meters; if used at higher altitudes, the rated insulation level should be accordingly increased. The VS1-12 can maintain its reliability even in conditions of high relative humidity, up to 95%, making it suitable for humid environments. This device is also designed to safely operate in regions with earthquake intensities up to level 8. However, it should not be used in environments prone to fire, explosion, severe pollution, chemical corrosion, or intense vibration.
Application Scope
The VS1-12 series vacuum circuit breaker is a critical switchgear component widely used in industrial and mining enterprises, power plants, and substations. It is particularly suitable for environments requiring frequent operations, such as power dispatch centers and industrial manufacturing facilities. The device can be utilized as a fixed installation unit or conveniently moved and used across different locations through its trolley-type structure. Its main circuit's solid-sealed pole design ensures high reliability and maintenance-free operation while maintaining a compact form factor. Additionally, the VS1-12 is compatible with centrally-mounted trolley switchgears like KYN28A-12(GZS) and can also work with XGN series fixed switchgears, demonstrating its versatility in various power systems.
Precautions
When installing and using the VS1-12 series vacuum circuit breaker, ensure that the device is operated within the recommended environmental conditions, avoiding usage in temperatures outside the specified range or excessively humid conditions. The device should also be kept away from environments that may pose fire, explosion, or chemical corrosion hazards to prevent adverse impacts on its performance. Always follow the relevant safety protocols during operation and maintenance to ensure the safety and reliability of the device.
