GY101Series Microcomputer Monitor and Protection Devices for Electric Motors (hereinafter referred to as):The protector is the crystallization of our company's experience in manufacturing similar motor protection products, combining independent intellectual property rights and software copyrights.,As perIECAn intelligent, digital, and networked protector developed to international standards. The protector comprehensively collects and tracks various parameter information during the operation of the motor. It achieves timely and accurate protection through fault alarms, protective actions (protective tripping), and the setting of action delay times, significantly ensuring the effectiveness of safe and normal production of equipment. When the motor operating parameters reach the preset warning values, the protector only issues an alarm without triggering a trip; however, when the over-limit values reach the preset trip values, the protector enters a trip trigger delay. If the equipment returns to normal operation within the preset trip delay time, the trip is canceled; otherwise, if the delay time is exceeded, the protector sends a trip signal, driving the operation of the relay to stop the equipment. In addition to implementing various protection functions, it also provides various protection information parameters and...RS485Communication interface to computer control for remote management, capable of network communication with various microcomputer industrial control configuration software, and can also output analog quantities4-20mAManner andDCSSystem connectivity transmits motor operating parameters, forming a distributed comprehensive power monitoring system. This product is based on micro-processing technology, integrating network communication technology and distributed intelligent technology.MCCControl center integrating intelligent motor protection, operation status monitoring, motor operating time accumulation recording, and network communication; capable of viewing measurement data, fault information management, setting parameters, and meeting various startup methods. The protector can also act as a digital function, displaying three-phase working current, voltage, and set protection values; at the low-voltage control terminalMCCCabinet1/4Drawers of units and above can be directly installed and used. The protector provides complete protection for the motor, avoiding overloading, underloading, stalling, under-voltage, over-voltage, and grounding./Leakage, short circuit, phase failure/Three-phase current unbalance, startup timeout, feeder circuit protection, and other production safety issues. It is suitable for industrial motors and three-phase power systems in the power, chemical, mining, cement, metallurgy, building materials, and textile industries. The standard configuration of the protector, with its comprehensive functions, greatly simplifies traditional equipment maintenance, reduces maintenance costs, and thus provides a scientific and effective on-site protection and measurement and control unit for the industrial production process.
