Abstract
The invention relates to a motor stator temperature measuring device. The motor stator temperature measuring device comprises a stator core and a slot wedge, wherein a coil of the stator core is arranged in a slot opening of the stator core, the slot wedge is arranged in the slot opening of the stator core and is used for fixing the coil of the stator core, a concave groove is arranged in the contact position of the slot wedge and the coil, the size of the concave groove is matched with the size of a temperature measuring element, and the temperature measuring element is arranged in the concave groove of the slot wedge. Due to the fact that the temperature measuring element is arranged in the concave groove at the lower portion of the slot wedge, full contact between the temperature measuring element and the coil of the stator core is guaranteed, the temperature measuring element can be replaced just by taking out the slot wedge, the temperature measuring element is protected from being damaged easily, and the temperature measuring element is replaced easily at the same time. The invention further relates to an alternating current motor.
Description
Technical field
The present invention relates to machine field, relate in particular to a kind of motor stator temperature measuring equipment and alternating current machine.
Background technology
Alternating-current motor stator is existing to be placed in stator core slot between upper and lower coil usually with temperature element, slot wedge is placed in the notch of stator core for the coil of fixed stator iron core, this temperature element is installed more difficult, and be subjected to upper and lower coil extruding easily to cause temperature element to damage after installing, particularly, can't change after damage, causing can't thermometric after damage.
Summary of the invention
Purpose of the present invention overcomes above defective, a kind of installation is provided, changes motor stator temperature measuring equipment and alternating current machine easily.
Technical scheme of the present invention is, a kind of motor stator temperature measuring equipment, it comprises stator core, slot wedge, the coil of stator core is placed in the notch of stator core, slot wedge is located at the notch of stator core for the coil of fixed stator iron core, described slot wedge and coil contact position are provided with groove, and the size of groove and the overall dimension of temperature element are complementary, and described temperature element is placed in the groove of slot wedge.
Described temperature element viscose glue is in groove.
Described temperature element be by the epoxy resin viscose glue in groove.
The present invention also provides a kind of alternating current machine, and it comprises the stator temperature measuring equipment, and described stator temperature measuring equipment is stator temperature measuring equipment described above.
Technique effect of the present invention is; owing to temperature element being placed in the groove of slot wedge bottom, guaranteed that not only temperature element contacts fully with the stator core coil, and only need to take out slot wedge be replaceable temperature element; both protected temperature element not fragile, changed easily simultaneously.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the slot wedge structure schematic diagram.
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, it comprises stator core 1, slot wedge 2, stator coil 3 is placed in the groove of stator core 1, slot wedge 2 is located at the notch of stator core 1 for the coil 3 of fixed stator iron core 1, slot wedge 2 is provided with groove with stator coil 3 contact positions, the overall dimension of the size of groove and temperature element 4 is complementary, and temperature element 4 passes through the epoxy resin viscose glue in the groove of slot wedge 2.
The present invention also provides a kind of alternating current machine, and it comprises the stator temperature measuring equipment, and described stator temperature measuring equipment is stator temperature measuring equipment described above.Because the said stator temperature measuring equipment has above-mentioned technique effect, the alternating current machine with this stator temperature measuring equipment also should have above-mentioned technique effect, introduces no longer in detail at this.
