Technical field
The utility model is related to Protection Technology for Motors field, specially a kind of motor protection dress with WIFI interface
It sets.
Background technology
Since motor is widely used in the industries such as cement, steel, power plant, papermaking, metallurgy, electric motor protecting is motor
Comprehensive protection is provided, i.e., overload, phase shortage, stall, short circuit, overvoltage, under-voltage, electric leakage, three-phase imbalance, mistake occurs in motor
When heat, bearing wear, rotor bias, is alarmed or protected;The device that protection is provided for motor is motor protecter, packet
Electrothermal relay, electronic protector and smart protectors are included, large-scale and important motor is generally filled using intelligent protection at present
It sets, often uses the monomer protected mode of independent protective function, for industry internet field, the protection of monomer is in networking mode
See have clearly disadvantageous in debud mode and the facility of operation.
Electrothermal relay is the protection electric appliance for motor overload protection.In actual operation, such as dragging produces motor
Machinery carries out in the course of work, if machinery abnormal situation or circuit abnormality occurs and motor is made to encounter overload, motor
Rotating speed declines, the electric current in winding will increase, and the winding temperature of motor is made to increase.If overload current less and overload time
Shorter, motor winding, which is no more than, allows Wen Sheng, this overload to be allowed.But if overload time is long, and overload current is big, electronic
The temperature of machine winding, which rises, to be more than permissible value, make motor winding aging, shorten the service life of motor, even meeting when serious
Make motor winding.It cannot be born so this overload is motor.Electrothermal relay is exactly the fuel factor using electric current
Principle cuts off motor circuit when there is overload that motor cannot be born, and the protection electricity of overload protection is provided for motor
Device.
Electronic motor protector develops to integrated circuit by transistor and has developed to micro-chip processor thickness mould so far
Circuit is functionally generally divided into open-phase protection, integrated protection (multifunction protection), temperature protection and intelligent protection.Such guarantor
Shield utensil have it is energy saving, be active in one's movements, accuracy is high, impact resisting vibrating, it is reproducible, defencive function is complete, small power consumption the advantages that.
Motor occurs for the motor protecting device of the protection of smart protectors collection, telemetering, communication, remote control and one
Protection is realized when the failures such as disconnected phase, overload, short circuit, under-voltage, over-pressed and electric leakage, also there is Current Voltage to show that time control is soft
Part self diagnosis, self- recoverage of sending a telegram here, self-starting sequence, trouble and managing, from trivial and teletransmission alarm, electric current, voltage when showing failure
Failure is front and back to be warned with code name flicker, is configured RS485 communication interfaces, is realized computer networking.Can monitor simultaneously, monitor hundreds of,
The functions such as thousands of electric motor operations.
Above several protectors are all the original functions from conventional motors, according to the running current curve of motor and
The working characteristics of motor, the traditional protection device designed and developed, the networking requirement for industry internet and industry 4.0, and
Field application demand is cannot be satisfied, market in urgent need is a kind of there can be the reliable wireless protector interconnected automatically, and it is existing to complete industry
The comprehensive interconnection and control of field motor, while having both electromotor integrated protection function.
