Abstract
The invention discloses the fixing means that a kind of refrigerant compressor motor winding overhang insulate mutually, by adopting the binding strap with good insulating performance, colligation is carried out to the winding root that electrically isolates from mutually between phase and phase inserting winding, make to insulate mutually and fix in the realization between phase and phase of winding and not easily occur slippage or displacement, thus ensure that motor can safety and stability reliably be operated in refrigerant compressor.The method is simple, easy to operate, has good practicality, and what have effectively achieved that motor winding insulate mutually is fixing.
Description
Technical field
the present invention relates to the fixing means that a kind of refrigerant compressor motor winding overhang insulate mutually.
Background technology
comparatively speaking, threephase asynchronous there is higher voltage between phase and phase, especially, when such as thunder and lightning, transient voltage, start or shutdown etc. are abnormal, this all may cause motor to burn in the occurring phase fault between phase and phase of motor.In order to ensure that motor can run to normal reliable, preventing the situation occurring short circuit between phase and phase, between the three-phase of motor winding, generally all increasing the material of one deck phase insulation to realize the insulation mutually of motor.
motor for closed type refrigeration compressor and common standard motor (as Y-series threephase asynchronous) all have larger different on operational environment and structure, the common motor that motor for closed type refrigeration compressor compares same power is little many on build, the more important thing is that the end of winding is short a lot, in general be 2/3 of Y-series motor, some be even only its 1/2.In this case, motor is easy to occur that insulation is sent not in place mutually in the process made, or deliver to position in manufacturing process after, occurs again the situation of slippage or displacement in the processing in later stage.Like this when compressor operating, due to reasons such as mechanical oscillation, just burn-down of electric motor may be caused because the weak part of this insulation occurs insulation breakdown.
Summary of the invention
the object of this invention is to provide the fixing means that a kind of refrigerant compressor motor winding overhang insulate mutually, thus prevent refrigerant compressor motor phase insulation-displacement, ensureing insulate mutually is reliably fixed on motor between phase and phase.
for achieving the above object, the technical solution used in the present invention is: the fixing means that a kind of refrigerant compressor motor winding overhang insulate mutually, and described fixing means comprises the steps:
(1) insertion is insulated mutually, and described insulation is mutually inserted into the root of winding;
(2) adopt the binding strap with good insulating performance to reel a few at the root of described winding along its outer circumference surface, described insulation is mutually pressed in below described binding strap;
(3) insulate described mutually along the root pull-out certain length of the axially past described winding of described winding, make the described relatively described winding root that insulate mutually stretch out a part, more described binding strap is compressed;
(4) the described inverse bending of insulation mutually stretching out winding root is pressed on described binding strap, then by described binding strap along the outer circumference surface of described winding root reel a few also compress, fixing.
preferably, described binding strap is one or more in polyester fiber band, electrician's alkali-free glass fibre band or non-woven polyester strap.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: carry out colligation by adopting the binding strap with good insulating performance to the winding root that electrically isolates from mutually between phase and phase inserting winding, make to insulate mutually and fix in the realization between phase and phase of winding and not easily occur slippage or displacement, thus ensure that motor can safety and stability reliably be operated in refrigerant compressor.The method is simple, easy to operate, has good practicality, and what have effectively achieved that motor winding insulate mutually is fixing.
Accompanying drawing explanation
accompanying drawing 1 is the fixing schematic diagram that insulate mutually of the present invention.
wherein: 1, iron core; 2, winding; 3, insulate mutually; 4, binding strap.
Embodiment
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Figure 1, the fixing means that a kind of refrigerant compressor motor winding overhang insulate mutually, this fixing means mainly comprises the steps:
first will insulate 3 insertion windings 2 mutually between phase and phase, and be inserted into the root to winding 2, then the binding strap 4 with good insulating performance is reeled a few at the root of winding 2 along its outer circumference surface, and 3 to be pressed in insulating mutually below binding strap 4.Binding strap 4 can be one or more in polyester fiber band, electrician's alkali-free glass fibre band or non-woven polyester strap.3 still slippage or displacement can be there is due to reasons such as mechanical oscillation in order to insulate mutually after preventing binding strap 4 colligation, at this moment 3 axially certain length is pulled out toward the root of winding 2 along winding 2 by insulating mutually, the root of 3 relative windings 2 of making to insulate mutually stretches out a part, again binding strap 4 is compressed, now also compress and insulated 3 mutually, again insulation mutually 3 inverse bending stretching out winding 2 root is pressed on binding strap 4, then by binding strap 4 along the outer circumference surface of the root of winding 2 reel a few also compress, fixing.Insulate so mutually 3 be namely fixed on winding 2 there is slippage or displacement between phase and phase and not easily, thus ensure that motor safety and stability is reliably operated in refrigerant compressor.The fixing means that refrigerant compressor motor winding overhang of the present invention insulate mutually, its method is simple, easy to operate, and prove through test, it has good practicality, and what have effectively achieved that motor winding insulate mutually is fixing.
above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
