With the development of motor industry,motor protector plays an indispensable in promoting modern economic development. But in the process of industry, motor also needs to be monitored and protected.Our comprehensive intelligent motor protectors which adopt wide-range -temperature and low-power-consumption 16-bit single chip microcomputer and intellectual property and software copyright, plays an important part in information collection, calculation, analysis, measurement and control, protection, alarm, monitoring, interlocking, controlling in the process of running. Its industries use almost permeates various fields of industry including agriculture, national defense, construction and normal operation of the three-phase motor used in the people's living and guarantees an effective security .Therefore, it’s significant of protection of the motor, which promotes energy saving, production efficiency improving and economic benefit and the safety in production.
The new generation of intelligent protector achieves computing power, accident analysis, motor fault report, etc. in addition to conventional low-voltage motor protection, monitoring and control function.As a comprehensive measurement, the motor protection control system can improve the reliability and security of the power supply system of the enterprise, improve automation management level of the enterprise in the operation of the production.
Use range
The motor is suitable for low voltage motor, rated current is less than 1000A, and the rated frequency is 50Hz. The functions of remote automatic control, field direct control, panel LCD full Chinese instruction, signal alarm and field bus communication are realized. Through the fieldbus, the integrated industry USES MODBUS-RTU communication protocol, which communicates with the intelligent MOTOR control center to realize remote measurement and control, protection and setting of MOTOR circuits.
Product is small in size, compact structure, convenient installation, in the low voltage control terminal cabinets and various drawer ark can be installed directly above a quarter and a quarter, improves the security and reliability of control circuit and automation management level.
Adopt the integration module structure to form integration,with the main body (protection control, operation, LCD display module), the transformer detection module. It is suitable for mining, chemical, cement, petrochemical, smelting, power, ship and civil construction..
Main features
Protection function: Overflow protection, underflow protection, open-phase protection, three-phase unbalanced protection, motor Shaft Lock Protection, under-voltage protection, overvoltage protection, start timeout protection, leakage protection, short circuit protection.
When the load of motor are carrying pump load, motor racing or running underflow, which causes serious damage, protector provides underflow protection. When the percentage of the average current and the rated current of the three-phase is lower than the set value, the protector should react in action (delay) setting time or alarm in the alarm time.
Motor in the process of starting or running, if electric shaft is stuck due to overload or own machinery, and did not remove the fault in time, will cause the motor overheating and burn motor. Locked-rotor protection is suitable for such fault protection when motor starts. Blocking protection is suitable for such a failure in the process of motor operation. When the current reaches action set current, protector should react in action (delay) setting time action or alarm in the alarm time.
When the harm of the motor occurs, open-phase(imbalance) protection operates. When the motor open-phase or three phase current serious imbalance occurs, such as imbalance rate reaches the protection setting, protector will set a parking or alarm instructions according to the requirements of setting to make motor run more safely.
leakage protection
The protector also has grounding protection and leakage protection. Earthing protection current signal comes from the vector and the inner current transformer, used for protection of motor metal case of short circuit. The protector can detect the fault current in 30 ~ 50mA through increasing leakage current transformer, is mainly used for indirect grounding to ensure personal safety.
When protector detect external faults, external fault switch input and protector switch input of the definition are inconsistent, the protector will react according to the requirements of setting to ensure the motor equipment safety.
The protectors with phase sequence protection function should not move when the voltage phase sequence of the power side is in accordance with the sequence of the set. The motor should not be started when the protective device detects that the phase sequence of the electric d is wrong.
Undervoltage protection
Low voltage will cause motor speed reduced, and even stop running. When the motor running voltage drops to set the range of low voltage protection, protector will react according to the requirements setting in action (delay) setting time or alarm in the alarm time, to avoid unnecessary chaos and serious impact production.
