Description
Technical field
The utility model belongs to electric motor starting protector technical field, and in particular to a kind of motor with double defencive functions
Start protection device.
Background technique
By taking common refrigeration compressor motor as an example, since it is little power single phase alternating current generator, thus need at the start
By starter auxiliary starter, and protection need to be implemented by protector after compressor enters normal operating condition and use guarantee refrigeration
Compressor disconnects power supply when there is overload condition in the process of running, avoids refrigeration compressor because of excessively thermally-induced damage.
In disclosed Chinese patent literature, it is no lack of and is seen in the technology about refrigeration compressor motor start protection device
Hold, such as CN2606490Y(electric motor starting, protector), CN2606491Y(Integral motor starting protector),
The improved Integral motor starting protector of CN102386815B(structure), CN100581043C(energy-saving type integral blow-up
Galvanic electricity machine rise protector), the energy-saving single phase AC electric motor starting protector of the improved idle of CN104734428A(structure),
CN104734429A(energy-saving type integral single phase AC electric motor protector), the energy-saving load motor of CN104734569A(
Start protection device), the energy-saving single phase AC electric motor starting protector of CN104734570A(idle) CN104734571A(energy conservation
Type integral single phase AC electric motor starting protector), etc..
It is not limited to patent exemplified above and is able to satisfy above-mentioned started by starter to motor assist and by protecting
Device disconnects power supply and plays the superheat protecting function to motor, but after mounting in actual use, often exist because of electricity
Machine starter abnormal heating cause protector fail to protection circuit situation.In particular, since protector failure is difficult to very
To can not be found by user such as refrigerator user at all, consequently only that can not work i.e. in load motor, refrigeration compressor is not
It is just fully realized for various reasons when work, but late.Because once such case occurs unquestionably trouble can be caused to user,
Such as replacement motor and related accessories (such as electric motor starting protector) can increase financial burden to user, for another example influence user
