[Brief] Shaanxi Electric Power Equipment Co., Ltd. Thailand Open ZW32 intelligent vacuum circuit breaker market, products are widely used in 10kV cities, villages distribution network overhead lines as the ring segments isolated switch, contact switch, may be imposed load distribution ring line automatic switching equipment, power users in large branch line as the boundary switch (commonly known as the watchdog) [Details] a, ZW32 intelligent vacuum breaker Quotes Product Overview ZW32-12F type field boundaries AC high voltage vacuum circuit breaker (hereinafter referred to as the boundary breaker) is my company developed a new self-product, the boundary is a vacuum breaker breaker, breaker boundaries, segmentation is open for one of the four multi-function intelligent equipment products, mainly with the vacuum boundary breaker body, BK600 controller, an external voltage transformer (Note: Distribution Automation ring lines bilateral optional PT) three constitute the majority of the products are widely used in 10kV cities, villages distribution network overhead lines ring for segmentation isolated switch, contact switch, may be imposed load distribution ring line automated switching devices, power users in large branch line as the boundary switch (commonly known as the watchdog), feeder for overhead distribution network boundary breaker The segment is used, vacuum circuit breaker with a long boundary management, protection and control functions and communication functions. Can distinguish solid inner boundary check mA level zero sequence current and phase short circuit current shortcomings, the automatic removal of single-phase ground faults and phase short circuit defects. Measures such as a reference to the contents of the device to use the book to clarify the boundaries of the circuit breaker rules regulate the use of environmental conditions, type and additional parameters, structural features, working principle, ordering instructions, as well as operation, equipment, use, protection. Two, ZW32 vacuum breaker market intelligence function features automatic removal of single-phase ground drawback occurs when the user extension to the disadvantage of the single-phase, the boundary breaker automatic gates, substations and feeder on the other branches of the user feel drawback occurs. Automatic isolation phase short circuit drawback occurs when a user extension phase short circuit shortcomings, the boundaries prior to the substation breaker tripped switch outlet protection, automatic line isolated shortcomings, other users will not touch the feeder branch of power outages. Quickly locate the shortcomings point, when the user branch circuit breaker protection action shortcomings constitute boundaries, only the responsibility of the user power, by automatically copy to the disadvantage of information, the power company can quickly send representatives to attend the investigation; boundary breaker as with communication module, automatically The CC information to the power management center. Monitor user load, when the boundary breakers can be equipped with a wired or wireless communication accessory to transfer the monitoring data to the power management center, end user load remote real-time data monitoring. Remote operation function, the user can go through SMS or computer background way to operate a vacuum circuit breaker sub-gate boundaries. Three, ZW32 vacuum breaker intelligent use of environmental market 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 When 25 ℃ 7) sunshine intensity (wind speed 0.5m / s)::% ??(25 ℃) 4) Earthquake talent: 0.3g ground horizontal acceleration vertical ground acceleration 0.15g 5) seismic intensity: 7 degrees 6) 0.1W maximum daily temperature / cm2 8) Maximum wind speed: 34m / s 9) ice thickness maximum: 10mm 10) Equipment Exposure: field, 10kV overhead line user responsibility demarcation point. 11) Ground way: ungrounded, arc suppression coil grounding and low resistance to ground. Four, ZW32 intelligent interpretation of the five types of vacuum circuit breaker market, ZW32 intelligent vacuum breaker breaker market product structure boundaries ZW32-12 vacuum circuit breaker has been optimized on the basis of improvement (see ZW32-12 clarify the use of the field voltage vacuum circuit breaker book) and external voltage transformer and MGK16 intelligent controller structure, after fully sealed waterproof seal air connectors and cable for electrical connection field. Use special boundary breaker spring operating organization (or permanent magnet organization), with the hand, the electric energy storage, hand, electric closing, hand, electric sub-gate function. External a boundary breaker zero sequence CT (or zero-sequence consisting of three), ratio of 20 / 1,0.1 ~ 5A (primary current) segment adhere linear relationship, the additional load 1Ω, change than the fault of the extra load should be less than 3%. A zero-sequence current is 400A, the secondary output current RMS is not less than 5A. Additional 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), the additional load 10Ω, accuracy 10P20, additional short-time withstand current 16kA, 20kA, 4S . Selection of external boundary breaker PT, mounted on the power supply side, ratio 10000V / 220V, capacity of 300VA, precision 3P level, controller and circuit breaker operating power supply voltage signal by PT.
