High Voltage Outdoor Vacuum Circuit Breaker GB1984-2003 Automatically/Manually 50Hz Control Vacuum Circuit Breaker

Product Description:

ZW20-12(F) outdoor vacuum circuit breaker is three phase AC 50Hz outdoor HV switchgear is mainly used for rural and urban 10 kV outdoor distribution network, as a separate and combined load current, overload current, short circuit current and other similar places.

Its whole structure is a three-phase common box type, which is composed of an operating mechanism, a conductive circuit, an insulating system, a sealing element and a shell.

And it is supporting the corresponding intelligent remote terminals to meet the application needs of distribution automation.

· ZW20-12 (Z) Outdoor Intelligent High Voltage AC True Air Breaker with GSM Short Message Function

· Combination with dividing switch controller ZW20-12 (F) Outdoor dividing high voltage AC true air breaker.

 
 
Characteristics of the controller:

1.It can be equipped with a 485/232 communication interface, or achieve long-distance monitoring through fiber optics or wireless communication. After reclosing, it has an acceleration function: when the switch recloses due to a permanent fault.

2.When a permanent fault occurs, it automatically accelerates to trip.

3.Remote control/manual reclosing with acceleration to trip, and reclosing interlock: After the user repairs the line and restores power, if they forget to remove the grounding knife switch, it should accelerate to trip.

4.The delay time for reclosing can be adjusted for all three attempts.

5.The trip/reclosing circuit is designed to prevent false operation and has anti-reclosing functionality.

6.Zero-sequence current can differentiate between faults inside and outside the zone.

7.The remote control trip/reclosing adopts a design to prevent false operation.

 
 
 
Application:

1.Mining Operations: The ZW20 switch is used in mining operations to control and protect electrical equipment and power distribution networks in underground and surface mines.

2.Data Centers: The switch is utilized in data centers to ensure reliable power distribution and protection for critical IT infrastructure. It enables efficient load switching and safeguards against electrical faults.

3.Oil and Gas Industry: The ZW20 switch finds application in the oil and gas industry for controlling and protecting electrical equipment in refineries, pipelines, and offshore platforms.

4.Infrastructure Projects: The switch is used in various infrastructure projects, such as airports, seaports, and stadiums, for reliable power distribution and protection.

5.Water and Wastewater Treatment Facilities: The ZW20 switch is employed in water and wastewater treatment facilities to control and protect electrical equipment in pumping stations, treatment plants, and distribution networks.

 
 
Structure:

1.The controller is a microcomputer-based relay protection and monitoring device.

2.The controller has strong weather resistance and protection against condensation.

3.It is connected to the switch body through aviation connectors.

4.It has good connection reliability and a high protection level.

The controller has four input analog channels: Phase A current, Phase C current, zero-sequence current, and Phase BC voltage. The controller monitors the values of these analog inputs in real-time and compares them with set values to determine line faults and initiate corresponding actions.

Environmental conditions:

1 ambient air temperature: -40 ° C ~ + 70 ° C;

2 Altitude: not more than 3000 m

3 Ambient air may be contaminated by dust, smoke, corrosive gases, steam or salt spray. Contamination Level: Class IV:

4 Wind speed does not exceed 34 m / s (equivalent to 700 Pa on the surface of the cylinder);

5 Vibration or ground motion from outside the switchgear and control equipment is negligible;

6 The amplitude of induced electromagnetic interference in the secondary system does not exceed 1.6kV.
