GY201is a series of all-round intelligent motor protector which imports IC, intellectual property patented technology and the software copyright production.GY201 adopts the microprocessor to execute the motor protection and control, and support the feeder protection, complete the motor operation, self-diagnosis and communication with PC, etc. It provides measurement for motor protection to avoid the production accidents because of motor overload, locked-rotor, overvoltage, undervoltage, light load, open phase, three-phase imbalance, grounding failure, to ensure the normal operation of the equipment.
GY201系列具有先進的現場總線接口,基於微處理器技術開發研製的電機保護與控制裝置。由微處理器來執行電機的保護與控制功能,完成對電機操作次數的統計、自診斷以及與上位機的通訊等。GY201為電機提供的完備保護,避免了因電機過載過熱、堵轉、欠壓、過壓、輕載、斷相、三相不平衡、接地、漏電等可能故障導致的生產事故,最大限度地保証設備運行的有效性與安全,GY201採用RS485通訊接口設計,保証了與上位機、PLC、DCS通訊的快速可靠,同時能快速響應上位主機的實時查詢等要求並執行相應操作。使用簡單方便,安全可靠。
適用範圍
This microcomputer monitoring protector is a comprehensive device for collecting, calculating, analyzing, monitoring, alarming and controlling of various running information data in the operation of the motor. The device can provide immediate and accurate protection and ensure the safety of the production by means of alarm, protection action (protection of unbuckle) and the setting of time-delay time. The device can carry out real time monitoring on the upper computer about the slim information of the motor running condition through the data communication and provide the management information by computer data processing. The limit alarm can timely remind administrative staff to deal before a significant fault may happen, which can avoid the unnecessary downtime or affect the normal production, to ensure effectiveness of operation and control to the maximum. When the motor running parameter reaches the preset warning value, the protective device only has the warning, and does not trigger the tripping; But when the limit reaches the preset value, the protection device enters the trip trigger delay. If the device returns to normal operation in the preset trip time delay, the trip will be canceled. If the delay time limit is exceeded, the protective device will emit a trip signal to drive the action of the element, and disconnect the power to stop the motor running. While the motor control device provides various protection functions, various protection information is also sent to the computer management system via the device generation and communication interface.
實現對電動機的遠程自動控制、現場直接控制、面板指示、信號報警、現場總線通信等功能。通過現場總線,集成工業用MODBUS-RTU通訊協議,通過和智能化的MOTOR控制中心通信,實現對電動機迴路的遠程監控。產品體積小,結構緊湊,安裝方便,在低壓控制終端櫃和1/4模數及以上各種抽屜櫃中可直接安裝使用,提高了控制迴路的可靠性和自動化水平。
採用模塊化的產品結構形式,包括主體(保護控制功能模塊)、互感器檢測模塊、(遠程)顯示模塊。適用於煤礦、化工、水泥、石化、冶煉、電力、船舶、以及民用建築等領域。
保護功能
過載保護、輕載保護、斷相保護、三相不平衡保護、堵轉保護、欠電壓保護、過電壓保護、啟動超時保護、漏電保護、短路保護。
當電動機所帶負載為泵式負載時,電動機空載或欠載運轉會產生危害,保護器提供欠載保護,當三相的平均電流與額定電流的百分比低於設定值時,保護器應在動作(延時)設定時間內動作或在報警時間內報警。
顯示監測
LDC半中文顯示運行狀態、三相電流、線電壓、漏電電流、電機溫度、故障信息顯示,LED指示電動機故障信息。
現場總線功能
GY201具有RS-485 遠程通訊接口,支持MODBUS-RTU、總線協議,方便的和PLC、DCS及後臺機組成網絡系統或採用電流變送4-20毫安輸出與後臺機相連接監控。通過後台機對現場設備進行實時操控、運行狀態參數監測和曆史數據查詢。GY201對電機運行狀態和故障原因監控記錄極大方便了對電機維護計劃的制定,降低了設備維護成本。
