Features:
VJG-Z intelligent vacuum circuit breaker is aimed at the shortcomings of current regular maintenance and post-maintenance of high-voltage switches. Jiangsu Senyuan developed on the basis of mature and reliable VJ12 circuit breaker, combined with online monitoring technology, and introduced the concept of integrated circuit breaker A new type of indoor switchgear can be used as power grid equipment.
The advantages of VJG-Z intelligent vacuum circuit breaker compared with conventional circuit breaker:
(1) Perfect on-line mechanical characteristic detection, current measurement of opening and closing electromagnets and energy storage motors, temperature rise measurement of the main circuit, and real-time monitoring of the operating status of the circuit breaker according to this, discovering possible hidden dangers in advance and ensuring equipment safety Reliable operation.
(2) Integrated circuit breaker. The current transformer and integrated protection measurement and control device are integrated in the circuit breaker, so that a single circuit breaker can constitute the entire measurement, protection and control unit.
(3) The circuit breaker is electrically driven in and out. The circuit breaker can be controlled remotely, not only ensuring the personal safety of the operator, but also preventing the occurrence of misoperation from the software program.
