Abstract
The utility model discloses a hardware platform of a motor protector, which comprises a protection control module and a display module. The protection control module is connected with the display module via a bus, and comprises a protection control CPU (Central Processing Unit) and a temperature acquisition module and a relay output module connected with the protection control CPU; and the display module comprises a display CPU and a man-machine interface circuit connected with the display CPU. Working temperature of a motor is detected by the temperature acquisition module, and then processed by the protection control CPU, wherein when the working temperature of the motor is higher than a preset parameter, the relay output module is triggered to disconnect a relay, thereby preventing the motor from burn-out.
Description
Technical field
The utility model relates to the protective device for power equipment, is specifically related to the hardware platform for the protection of motor.
Background technology
Motor protector is the intelligent monitor system that adopts microprocessor system and peripheral system structure to form.By the collection three-phase current, three-phase line voltage, data such as leakage current/earth current compare the various defencive function information of adjusting that record with protector after these data computation, when meeting the protection operation condition, drive the relay output signal.Electric elements such as motor protector and contactor, motor starter constitute the Motor Control protected location, have functions such as remote auto control, scene are directly controlled, panel indication, signal alarm, field bus communication.Be applicable to fields such as colliery, petrochemical industry, smelting, electric power, boats and ships and civil buildings.
The hardware platform that existing motor protector adopts can be monitored the current/voltage of motor, but can not monitor, show the temperature of motor.When the situation of short circuit or stall appears in motor, can not in time report to the police, outage will cause motor to burn automatically.The motor protector hardware platform generally includes protection control module and display module; using communication bus to carry out exchanges data between the two connects; but can produce the EMC effect, make protector be subjected to outside electromagnetic interference easily, also can produce electromagnetic interference influences other equipment.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The utility model content
The purpose of this utility model provides a kind ofly can be monitored, show motor temperature, prevents the motor protector hardware platform that motor burns.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of motor protector hardware platform is provided, comprises protection control module and display module, the protection control module is connected with display module by communication bus.The protection control module comprises protection control CPU and the temperature collect module and the relay output module that are connected with protection control CPU; Display module comprises demonstration CPU and the man-machine interface circuit that is connected with demonstration CPU;
Preferably, the man-machine interface circuit comprises LCD, film key and indicator light.
Preferably, the protection control module comprises the analog output module that is connected with protection control CPU.
Preferably, communication bus comprises Serial Port Line, is provided with two magnet rings at Serial Port Line.
In sum, the utility model advantage: 1, the serviceability temperature acquisition module is monitored the temperature of motor work, and by protection control CPU processing signals, the on off state of relay output module control contactor prevents that motor from being burnt.2, the Serial Port Line two ends of communication bus are equipped with magnet ring, and the EMC effect that effectively weakened has increased the fail safe of motor operation.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
The utility model is a kind of motor protector hardware platform, as shown in Figure 1, comprises protection control module and display module, and the protection control module is connected with display module by communication bus, and the signal that collects is transferred to display module.
The protection control module comprises protection control CPU and the temperature collect module and the relay output module that are connected with protection control CPU; Temperature collect module uses PTC thermistor collecting temperature signal and temperature signal is sent to protection controls CPU, and protection control CPU carries out temperature signal filtering, amplifies and handle, and is transferred to the display module demonstration.Motor carries out the parameter setting to motor protector before operation, when motor caused temperature to be higher than set point because of short circuit or stall, protection control CPU can send to relay output module by signal, and the contactor of motor is cut off; Motor cuts off the power supply automatically, thereby avoids motor to burn, and reaches the purpose of protection motor.
The display module of hardware platform comprises demonstration CPU and the man-machine interface circuit that is connected with demonstration CPU.The man-machine interface circuit comprises LCD, film key and indicator light, by film key can switching liquid crystal display display interface.The protection control module sends to the signal that receives and shows CPU, and demonstration CPU sends to the man-machine interface circuit after signal is handled, and shows that in LCD operating personnel can be directly acquainted with the working temperature of motor.
The motor protector hardware platform can be measured the current and voltage signals of motor, the running status of monitoring motor.The motor hardware platform is provided with and the analogue collection module of protecting control CPU to be connected, current/voltage is carried out signals collecting, and the signal that collects is the big voltage and current signal of amplitude.For the better protection motor, motor protector is connected with the DCS system, but the DCS system can not identify the big voltage and current signal of amplitude.The protection control module comprises the analog output module that is connected with protection control CPU.The current and voltage signals that analog output module is big with amplitude converts the small-signal of 4-20mA to, and motor protector can be connected with the DCS system.
Further, communication bus comprises Serial Port Line, for the EMC effect that weakens, is provided with two magnet rings at Serial Port Line.
Though by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection range of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection range of this patent.
