Intelligent High Voltage Three Phases Grey Vacuum Circuit Breaker With Controller For Distribution Networks

Intelligent High Voltage Three Phases Grey Vacuum Circuit Breaker With Controller For Distribution Networks

Product Description:

The ZW20-12(F) High Voltage Vacuum Circuit Breaker is a versatile and intelligent device that combines the functions of a vacuum breaker, vacuum load switch, recloser, and sectionalizer. It is designed for use in 10kV and 13kV distribution networks, specifically in city and rural power grids.

The main components of the ZW20-12(F) circuit breaker include a vacuum breaker, CH-40 controller, and an external voltage transformer. The vacuum breaker is responsible for interrupting and making electrical circuits, while the CH-40 controller provides intelligent protection and control functions. The external voltage transformer helps in accurate voltage measurement for control and monitoring purposes.

Characteristics of the controller:

Intelligent terminal controllers have functions such as protection, automatic control, inspection/query, communication, and software management.

1.Comprehensive Functionality:

• Perfectly implement various functions such as circuit protection, remote control, alarm, and remote monitoring.

2.Low Cost and Practicality:

• No need for any communication hardware investment in GSM networks. Simply purchase a SIM card and activate SMS services.

3.Multiple Security Measures:

• Use designated mobile phones, information encryption, password verification, and other security measures.

• The GSM module can specify a mobile number and only accept commands from the bound phone.

• Communication messages for remote control and other commands are encrypted.

• Follows a pre-set-confirm-execute-verify remote control method to ensure the security of system control and prevent misoperations.

4.Simple System Configuration:

• No need to install any communication lines or debug communication lines.

• Simply install the SMS intelligent monitoring terminal correctly, insert the SIM card, set the designated mobile number, and the system will start running.

5.Mobile Monitoring Anytime, Anywhere:

• Real-time monitoring and viewing can be done in any location with a signal, without the need for personnel to be stationed for monitoring.

1.High breaking capacity: It is capable of interrupting high fault currents and protecting the electrical system from overcurrent conditions.

2.Compact design: The switch is designed to be compact and space-saving, making it suitable for various installation environments.

3.Reliable performance: The vacuum interrupter technology used in the switch ensures reliable switching operations and minimal maintenance requirements.

4.Long electrical and mechanical lifespan: The switch is designed to have a long operational lifespan, with high endurance and durability.

5.Protection features: It may include features such as overcurrent protection, short-circuit protection, and other protective measures to safeguard the electrical system.

6.Remote control and monitoring: Some models of the ZW20 series may offer remote control and monitoring capabilities, allowing for convenient operation and status monitoring.

 
 
 
Environmental conditions:

1.The ZW20-12(F) automatic vacuum circuit breaker is designed to operate reliably within a wide ambient air temperature range, from -40 °C to +70 °C. This temperature tolerance ensures that the circuit breaker can function effectively in various climatic conditions.

2.The circuit breaker is suitable for installation at altitudes not exceeding 3000 meters above sea level. This altitude compatibility allows for flexible deployment in different geographic locations.

3.The ZW20-12(F) circuit breaker is built to withstand ambient air contamination caused by dust, smoke, corrosive gases, steam, or salt spray. It is designed to meet Class IV contamination level standards, ensuring that the circuit breaker remains resilient and operational even in challenging and corrosive environments.

4.With a maximum wind speed tolerance of 34 m/s (equivalent to 700 Pa on the surface of the cylinder), the circuit breaker can withstand strong winds without compromising its performance or stability. This wind speed resistance ensures the reliable operation of the circuit breaker during extreme weather conditions.

5.The circuit breaker is designed to minimize the impact of external vibrations or ground motions on its performance. Its construction and internal mechanisms are engineered to absorb and dampen vibrations, ensuring that the circuit breaker remains unaffected by external disturbances.

6.The ZW20-12(F) circuit breaker is designed to limit induced electromagnetic interference (EMI) in the secondary system. The amplitude of the induced EMI in the secondary system does not exceed 1.6kV, ensuring that the circuit breaker does not generate excessive electromagnetic disturbances that could interfere with the operation of other connected equipment.
