Detailed Product Description: | I. Product Overview ZW32-12 Outdoor AC high voltage vacuum circuit breaker boundaries (hereinafter referred to as the boundary breaker) is my company developed a new type of product, the boundary breaker is a vacuum circuit breaker, breaker boundaries, slicer four open on multifunctional intelligent device products, mainly configured by the vacuum breaker body boundaries, MGK16 controller, an external voltage transformer (Note: Distribution Automation ring lines bilateral optional PT) three parts composition, the products are widely used in 10kV urban and rural distribution network overhead lines ring segments for isolating switch, contact switch, can implement ring deployment automation line load switching devices, power users in large branch lines as boundaries switch (commonly known as the watchdog), feeder breaker overhead distribution networks for demarcation purposes slicer, vacuum breaker boundaries with remote management, protection and control functions and communication functions. Reliable judgment, within the detection boundary milliamps and zero-sequence current phase short circuit fault current, automatic removal of single-phase ground fault and phase fault. Referenced standards, the use of environmental conditions, type and nominal parameters, structural features, working principle, ordering instructions, as well as the operation, installation, use, maintenance, installation methods, such as the contents of this manual provides a boundary breaker. Second, the functional characteristics of the automatic removal of single-phase ground fault occurs when the user branch single-phase ground fault, the boundary breaker automatic gates, substations and feeder on the other branches of the user feel failure. Automatic isolation phase short circuit fault occurs when a user extension phase short circuit fault, the boundary before the substation circuit breaker tripping outlet protection switch, automatically isolate the fault line, the user will not spread to other branches of the feeder on the power outage. Quickly locate the point of failure, when the user branch breaker failure caused by boundary action, only the responsibility of the user power, fault information submitted by the initiative, the power company can quickly sent to the scene investigation; boundary breaker as with communication module automatically will submit the information to the power management center. Monitor user load, when the boundary breakers can configure wired or wireless communication accessory to transfer the monitoring data center power management to achieve real-time remote user load data monitoring. Remote operation feature, users can operate the vacuum boundary breaker sub-gate via SMS or computer background mode. Third, the use of environmental conditions 1) Altitude: ≤2000 m 2) Ambient temperature: outdoor -30 ℃ ~ + 55 ℃ The highest annual average temperature of 20 ℃ highest daily average temperature 30 ℃ 3) Relative Humidity: 95% (25 ℃) 4 When 25 ℃ 7) sunshine intensity (wind speed 0.5m / s)::) seismic capacity: 0.3g ground ground horizontal acceleration vertical acceleration 0.15g 5) seismic intensity: 7 degrees 6) The maximum daily temperature 0.1W / cm2 8) maximum wind speed : 34m / s 9) ice thickness maximum: 10mm 10) installation location: Outdoor, 10kV overhead line user responsibility demarcation point. 11) Grounding: ungrounded, arc suppression coil grounding and low resistance to ground. Model and meaning five, the product structure of the boundary breakers in ZW32-12 vacuum circuit breaker has been optimized on the basis of improvements (see ZW32-12 outdoor high voltage vacuum circuit breaker manual) and external voltage transformer and intelligent control MGK16 composed by sealed waterproof outdoor air connectors and cable sealing electrical connections. Boundaries using a dedicated circuit breaker spring mechanism (or permanent magnetic actuator), with hand, electric energy storage, hand, electric closing, hand, electric sub-gate functions. External a boundary breaker zero sequence CT (or three synthetic zero-sequence), ratio of 20 / 1,0.1 ~ 5A (primary current) segment to maintain a linear relationship, rated load 1Ω, variable ratio error at nominal load should be less than 3%. A zero-sequence current is 400A, the secondary output current RMS is not less than 5A. Rated short time withstand current 16kA, 20kA, 25kA, 4S. External boundary breaker 2 (or 3) single-phase CT, ratio 50-600 / 5 (or user-specified ratio), rated load 10Ω, accuracy 10P20, rated short time withstand current 16kA, 20kA, 4S . Boundary breaker using external PT, mounted on the power supply side, ratio 10000V / 220V, capacity of 300VA, precision 3P level, operating power and voltage signal controllers and circuit breakers provided by PT.
