Abstract
The utility model discloses a motor temperature control protection system. The motor temperature control protection system comprises a temperature controller and an alarm and further comprises an interlock circuit, wherein the temperature controller is connected with a motor through a temperature sensor and is further connected with the alarm through an alarm circuit, and the interlock circuit is connected with the temperature controller and is further connected with the motor. According to the motor temperature control protection system, one or more micro temperature sensors are mounted on a motor bearing or proper positions of a machine, so a temperature signal can be transmitted to the temperature controller in real time, alarm temperature and interlock temperature can be set in the temperature controller. When temperature rises to the alarm temperature, the temperature controller outputs a signal to drive the alarm device such as an alarm ring or light; when temperature rises to the interlock temperature, the temperature controller outputs a signal for interlock with a motor control system to stop the motor, so the motor is protected from being burned out.
Description
Technical field
The utility model relates to electric motor protective device, specifically a kind of motor temperature control protection system.
Background technology
In production practices, often find the motor overheating phenomenon, if untimely discovery is easy to cause the burn-down of electric motor accident, namely influencing ordinary production has increased production cost again.
There are temperature sensor and control section in general large-size machine inside, but because controlling complexity, the cost height is difficult to be applied to middle and small motor.
The motor temperature height has a lot of reasons, as: phase shortage, turn-to-turn short circuit, coil aging ground connection, fan failure, bearing is stuck and damage, sweep hall, insufficient lubrication, ambient temperature height etc.Some superheating phenomenon can be protected by thermal relay, can not be protected when in most cases.
The utility model content
The purpose of this utility model is to provide motor temperature control protection system, surpasses the action of uniform temperature warning device, reminds operating personnel to note, shuts down when surpassing ceiling temperature startup interlock.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, and motor temperature control protection system comprises temperature controller, and described temperature controller is connected with motor.
Described temperature controller is connected with motor by temperature sensor.
Also comprise alarm, described temperature controller is connected with alarm.
Described temperature controller is connected with alarm by warning circuit.
Also comprise interlock circuit, described interlock circuit is connected with temperature controller on the one hand, is connected with motor on the other hand.
Compared to prior art, the utlity model has following beneficial effect:
The utility model is at motor bearings or fuselage proper site one or more mini-temperature sensors to be installed, and temperature signal is sent to temperature controller in real time, can set alarm temperature and interlocking temperature in temperature controller.The thermostat output signal drives warning device (as alarm bell, light etc.) when arriving alarm temperature.Thermostat output signal and electric machine control system interlocking are shut down motor when arriving the interlocking temperature, and the protection motor is unlikely to burn.In a word, the utility model can effectively be protected motor, can not burn motor because temperature is high, and is respond well.All middle and small motors all can use.
Description of drawings
Fig. 1 is motor temperature control protection system structural representation of the present utility model.
Embodiment
Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing only provides the usefulness of reference with explanation, and the utility model is limited.
With reference to accompanying drawing 1, motor temperature control protection system comprises temperature controller, alarm, and described temperature controller is connected with motor by temperature sensor on the one hand, is connected with alarm by warning circuit on the other hand.Also comprise interlock circuit, described interlock circuit is connected with temperature controller on the one hand, is connected with motor on the other hand.
Temperature sensor is sent to temperature controller in real time with temperature signal, can set alarm temperature and interlocking temperature in temperature controller.The thermostat output signal drives warning device (as alarm bell, light etc.) when arriving alarm temperature.Thermostat output signal and electric machine control system interlocking are shut down motor when arriving the interlocking temperature, and the protection motor is unlikely to burn.
