Zi Kai Auto Recloser With Intelligent Controller Use environment
1.Allow a certain degree of dust, smoke, corrosive gas, water vapor or salt spray in the surrounding air, and its pollution degree must meet the pollution level III standard.
2.Wind conditions need to be controlled at no more than 34 metres per second (this corresponds to a pressure of 700 pa generated on the surface of the cylinder).
Special application note
If you need to use circuit breakers outside of the normal operating conditions described above, please contact us and negotiate specific special requirements.
Zi Kai Auto Recloser With Intelligent ControllerFeature And Application
Feature
Fast response and recovery: After the instantaneous fault in the power system is detected, the circuit can be automatically disconnected quickly, and the fault is automatically overlapped after the fault is cleared, and the power supply can be quickly restored to reduce the power outage time.
Reduce equipment damage: Disconnect the circuit in time to prevent damage to the equipment in the state of continuous failure and protect the power equipment from further damage.
Prevent power grid shock: The intelligent control strategy is used to avoid unnecessary reclosing operations, reduce the risk of power grid being hit again when the fault is not cleared, and ensure the stable operation of the power grid.
Preventive maintenance: The real-time monitoring and early warning function enables you to detect and handle potential problems and faults in a timely manner, preventing problems from expanding, and reducing maintenance costs and overall operation and maintenance costs.
Application
Auto Recloser With Intelligent Controller is widely used in applications requiring high reliability power supply, such as:
Power system main network: used to protect transmission lines and substation equipment to reduce the scope and time of outages caused by failures.
Distribution network: In the urban and rural distribution network, it is used to improve the reliability of power supply and reduce the number of outages, especially suitable for industrial enterprises and residential areas with high requirements for power supply quality.
Special environment: In areas With harsh climate and complex environment, such as mountain areas and coastal areas, Auto Recloser With Intelligent Controller can adapt to various complex environments to ensure the stability and reliability of power supply.
