summary

VS1-12 indoor high-voltage vacuum circuit breakers serve as protection and control units for power grid equipment and power equipment of industrial and mining enterprises. It is suitable for frequent operation under rated working current, or for repeatedly switching off short-circuit currents. The circuit breaker adopts the integrated design of the operating mechanism and the body of the circuit breaker. It can be used as a fixed installation unit, or it can be equipped with a special propulsion mechanism to form a hand-car unit.

 

Main purpose

As power grid equipment, industrial and mining enterprises as a unit of power protection and control. It is suitable for places that require frequent operation under rated working currents, or repeatedly switch off short-circuit currents.

 

Performance and Features

Compliance with standards such as GB1984, DL/T403 and IEC 60056. Under normal conditions of use, within the range of technical parameters of the circuit breaker, it can be guaranteed to operate safely and reliably in the corresponding voltage level of the grid. The high-life mechanical life is 30,000 times, and the full-capacity short-circuit current is broken 50 times. Frequent operations or multiple short-circuit currents can be performed within the operating current range.

The high reliability is applicable to the overlapping gate operation of various characteristics;

All working conditions adopt vertical insulator to protect against the influence of various special environments;

Non-maintenance using solid insulation structure -- integrated sealed pole column;

Fully functional, multiple uses can be fixed, removable, and can also be installed on a frame;

The standardized design is interchangeable and versatile and is particularly suitable for use by KYN28(GZS1).
