WJB +05 Z Mai Long electrical WJB +05 Z Mai Long electrical WJB +05 Z Mai Long Electric Motor Intelligent Protector of the motor running in the process of running information and data acquisition, computing, analysis, monitoring, alarm, control device . Device through the alarm, fault protection action (protection trip), and the action delay time set to achieve timely and accurate protection to ensure the safety of the production. Intelligent motor protection device can communicate data, detailed information of the motor operating conditions on the host computer for real-time monitoring, 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 to avoid unnecessary downtime and impact on the normal production, to ensure equipment operation and effectiveness of controls. 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 value of the trip, the protection device into the release trigger delay. Preset trip delay time restore the unit 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 motor operation. The motor control device to achieve the protection function, a variety of protection of information generated by the device and sent to the computer management system via the communication interface. 
 Two main features: 
 Protection functions: overload protection, phase failure protection, three-phase unbalance protection, stall protection, under voltage protection, over voltage protection, leakage protection and earth 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 is displayed. 
 The set features: Rated current, to protect the current curve, start time, three-phase unbalance, stall multiples of the leakage current value, over and under voltage, mailing address, since the launch of the electric motor protector. 
 The FarEasTone: DC4-20mA standard analog output, no external power supply. 
 Communication: RS485 serial communication with the computer may constitute 256 the protector conventional protection and control network. Remote data set and display the alarm, remote motor start, stop and control. 
 Recall function: can store recently occurred in the motor 10 causes of failures, and press the reset button to remove the last motor failure code again to display the previous 
 Third, the main technical parameters: 
 Inverse time protection: this protection with overcurrent inverse-time delay protection function. 
 2, light-load protection: When the current value is less than the light-load protection settings, monitor action within 30 seconds. 
 3, over-current protection: protection of current can be set arbitrarily, the current value is greater than the set value, the operating characteristics curve movements. 
 4-phase protection: when the motor power off phase (produced three-phase current imbalance value is set to 60% according to user requirements), and monitor action in three seconds. 
 5, stall protection: protection action within 2 seconds when the motor operating current is greater than five times the set value. 
 6, under voltage protection: work voltage of less than 15% of the rated voltage, the protection action in six seconds. 
 , Over-voltage protection: work voltage higher than 15% of the rated voltage, the protective action in six seconds. 
 8, the leakage (ground) protection: leakage current is greater than the action of the monitor settings within three seconds, setting range 500mA ~ 5000mA. 
 9, short-circuit protection: When any one phase current to 8IE current protection action within two seconds. 
 10, the start delay time :1-120 seconds adjustable. 
 11, star delta conversion time: star delta conversion time is less than the start delay time of 3 seconds. 
 12 Overall Power Consumption: ≤ 3VA. 
 13, the output relay contact capacity: 25OVAC 7A. 
 14, the current error: ≤ 1.5%. 
 15, the reset time: ≤ 2 seconds. 
 16, the electrical life of greater than 10 times, with a start delay function: to avoid the start current and over-current operated separate times. 
 17, with RS485 remote communication interface or U-disk interface. With remote data set, control, inquiry. And the host computer network protection monitoring system.
