Description

Multifunctional electric motor-protecting device

Technical field

This utility model relates to a kind of Multifunctional electric motor-protecting device.

Background technology

At present, prior art motor mainly includes electromotor, motor, its in industrial and agricultural production and economic construction by extensively General use, for ensureing safety in production, reduces downtime, it is to avoid the generation of motor damage accident, existing have various multi-form Protection device, if any overload protection, overcurrent protection, open-phase protection, load Thermal protection, temperature current protection etc., But generally have circuit numerous and diverse, install inconvenience, high in cost of production defect.

Utility model content

For the problems of the prior art, this utility model provides a kind of Multifunctional electric motor-protecting device, this electric motor protecting Device can effectively prevent because the problems such as phase sequence change, change in voltage and motor temperature change cause the phenomenon of motor damage.

For realizing above technical purpose, the technical solution of the utility model is: a kind of Multifunctional electric motor-protecting device, including Input, Phase sequence detection module, voltage sample module, motor temperature detection sensor, sensor detection module, microprocessor mould Block and outfan, described input electrically connects with Phase sequence detection module and voltage sample module respectively, described Phase sequence detection module, Voltage sample module and motor temperature detection sensor all electrically connect with microprocessor module, described microprocessor module and output End electrical connection.

From the above, it can be seen that this utility model possesses advantages below: use multi-function motor of the present utility model Protection device is possible not only to ensure phase sequence change, change in voltage and the variations in temperature of monitoring motor and simple in construction, also simultaneously Temperature detection sensor can be in open circuit and short circuit detects, it is achieved that to the imbalance mutually of motor, misphase, phase shortage, Overvoltage, under-voltage, open sensor, short circuit sensor, motor temperature are too high, it is uneven to filter instantaneous phase sequence, uneven mutually Time, deferred action can be set；Microprocessor is simultaneously also by optimized algorithm simultaneously, mutually uneven and under-voltage etc. enters instantaneous Row filtering is filtered, and prevents owing to instantaneous of short duration imbalance causes machine down, and user loses.

Accompanying drawing explanation

Fig. 1 is the block diagram of Multifunctional electric motor-protecting device of the present utility model.

Detailed description of the invention

As it is shown in figure 1, a kind of Multifunctional electric motor-protecting device, including input 1, Phase sequence detection module 2, voltage sample mould Block 3, motor temperature detection sensor 4, sensor detection module 5, microprocessor module 6 and outfan 7, described input 1 point Do not electrically connect with Phase sequence detection module 2 and voltage sample module 3, described Phase sequence detection module 2, voltage sample module 3 and motor Temperature detection sensor 4 all electrically connects with microprocessor module 6, and described microprocessor module 6 electrically connects with outfan 7.

Multifunctional electric motor-protecting device of the present utility model is used to be possible not only to ensure the phase sequence change of monitoring motor, voltage Change and variations in temperature and simple in construction, can also be in open circuit simultaneously and short circuit detects temperature detection sensor, Achieve the imbalance mutually to motor, misphase, phase shortage, overvoltage, under-voltage, open sensor, short circuit sensor, motor temperature mistake High, can also to filter instantaneous phase sequence uneven, time uneven mutually, can set deferred action；Simultaneously microprocessor simultaneously also by Optimized algorithm, is filtered filtering to instantaneous mutually uneven and under-voltage etc., prevents owing to instantaneous of short duration imbalance causes machine Shutting down, user loses.

Being described this utility model and embodiment thereof above, this description does not has restricted, shown in accompanying drawing Also being one of embodiment of the present utility model, actual structure is not limited thereto.If generally speaking this area is general Logical technical staff is enlightened by it, in the case of creating objective without departing from this utility model, designing without creative and being somebody's turn to do Frame mode that technical scheme is similar and embodiment, all should belong to protection domain of the present utility model.
