The technical scheme that the utility model solve the technical problem employing is:
A kind of series machine that is provided with duplicate protection is provided, comprises rotor assembly and forward and backward support, and be installed on the stator module between this forward and backward support; Described stator module comprises stator core and installation in the inner and two stator winding that are mutually connected in series with the rotor assembly of series machine, and temperature detect switch (TDS); Described temperature detect switch (TDS) is electrically connected in series in the circuit of described two stator winding; Described stator module also comprises PTC thermistor, the electrical connection in parallel of this PTC thermistor and described temperature detect switch (TDS); After colligation, described temperature detect switch (TDS) is fixed on the end of arbitrary described stator winding together with PTC thermistor.
PTC is the abbreviation of English Positive Temperature Coefficient, and the Chinese meaning is positive temperature coefficient.PTC thermistor is exactly the thermistor of positive temperature coefficient.PTC thermistor is commonly called as fuse ten thousand times, and its feature is that its resistance value sharply rises when temperature rise is during to certain value; Its principle is exactly in the time that electric current exceedes certain value, and its power consumption increases, temperature rise; In the time that certain value is arrived in temperature rise, its resistance value sharply rises, thus blocking-up electric current, open circuit.PTC thermistor has the function of power-off protection and delay protection.
Described stator module also comprises temperature control protective sleeve and resistance cramp; described resistance cramp is fixed on described PTC thermistor on described temperature detect switch (TDS), and described resistance cramp, PTC thermistor and temperature detect switch (TDS) are entangled the rear end that is fixed on arbitrary described stator winding by colligation by described temperature control protective sleeve.
Also provide a kind of for the stator module on series machine, comprise stator core and installation in the inner and two stator winding that are mutually connected in series with the rotor assembly of series machine, and temperature detect switch (TDS); Described temperature detect switch (TDS) is electrically connected in series in the circuit of described two stator winding; Described stator module also comprises PTC thermistor, the electrical connection in parallel of this PTC thermistor and described temperature detect switch (TDS); After colligation, described temperature detect switch (TDS) is fixed on the end of arbitrary described stator winding together with PTC thermistor.
Compared with the existing technology, the utility model is provided with the series machine of duplicate protection and the beneficial effect of stator module is:
Carry out the security performance of General Promotion series machine by PTC thermistor of electrical connection in parallel on temperature detect switch (TDS).There are the abnormal conditions such as overload and stall during when series machine, temperature detect switch (TDS) disconnects automatically, now PTC thermistor can produce high temperature and high value, the high temperature of PTC thermistor can make temperature detect switch (TDS) remain open state always, thereby make series machine out of service, to avoid the equipment that is equipped with this series machine to be damaged; As made temperature detect switch (TDS) recover on-state, necessary hand-reset, be that user must first cut off the electricity supply a few minutes, and then switch on power, PTC thermistor recovers normal resistance value after starting to lower the temperature, after certain hour cooling, temperature detect switch (TDS) automatically resets, whole circuit switches on power again, described series machine could start and normally work, thereby avoids superheating phenomenon periodically to repeat, and has effectively improved fail safe when series machine uses, greatly improve the quality of series machine, brought safety to user's property and life.
