KJG-D Series motor protection

KJG-D Series motor protection is for the motor is running various operating information and data collection, calculation, analysis, monitoring, alarm, integrated device control. Device through the alarm, fault protection action (protection trip), and the action delay time set to achieve timely and accurate protection to ensure production safety. For more information KJG-D Series motor protector can also be data communication, motor operating conditions on the host computer for real-time monitoring, and management information and computer data processing. Before the device may have a significant failure, the more alarm can be a timely reminder of the management personnel for processing, to avoid unnecessary downtime and impact on the normal production, to ensure maximum effectiveness of the equipment operation and control. When the motor operating parameters to achieve the preset alarm value, the protection device only warning, without triggering the release; but when more limits to reach the preset trip level, the protection device into the release trigger delay. In the pre-trip delay time restore the normal operation, cancel the trip to perform; if more than delay the time limit, the protection device to issue the trip signal to drive the actuator action, disconnect the power to stop the motor running. The motor control device to achieve the protection function, while a variety of protection of information generated by the device and sent to the computer via the communication interface management system. Second, the main features: Function: Overload protection, phase protection, phase unbalance protection, stall protection, leakage protection, ground fault protection, light-load protection, no-load protection, short circuit protection. Control functions: direct start, pros and cons of starting, star delta starters, direct bypass starter, autotransformer reduced voltage starting, multi-start control. Monitoring: the running state, three-phase current, line voltage, leakage current, fault information, the cumulative time of motor work, the fault frequency information. The set features: Rated current, protect the current curve, start time, phase unbalance, stall multiples of leakage current mailing address. Remote features: a D-20mA standard analog output, no external power supply.
