The electromagnetic force that compressor 1 occurs in stator 7b by streaming current in winding 24, drives rotor 7a to rotate together with axle 6.And the part in winding 24 in mobile electric current divides electric current to leak towards stator core 23.
At this, in compressor 1, stator is directly fixed on the closed container of steel plate system, so, in the value (mobile leakage current is less than or equal to 1mA between the surface of charging part and device body) that must specify in electrical appliance administrative law in order human body not to be impacted.Therefore, must take some countermeasures and make leakage current in electric current mobile in winding 24, that leak towards stator core 23 be less than or equal to 1mA.
Leakage current away from identical with the principle of electric capacity, establishing leakage current is that i, frequency are that f, spuious electrostatic capacitance are that C, voltage are V, the relation of formula (1) set up.
(mathematical expression 1)
i＝2πfCV…（1）
Spuious electrostatic capacitance C between winding 24 and stator core 23 is, the distance of establishing dielectric constant between winding 24 and stator core 23 and be area between ε, winding 24 and stator core 23 and be between S, winding 24 and stator core 23 is d, and the relation of formula (2) is set up.
(mathematical expression 2)
C＝εS／d…（2）
(dielectric constant of R32)
But, compare with R410A, the R32 that the substitute of the conduct time generation cold-producing medium that greenhouse effects of the earth coefficient is low is studied, its DIELECTRIC CONSTANT ε is high.For example, the DIELECTRIC CONSTANT ε of the R410A at 40 DEG C is 7.7045, and to this, the DIELECTRIC CONSTANT ε of the R32 at 40 DEG C is 11.268.
That is to say, in the situation that R32 is used as to cold-producing medium, the spuious electrostatic capacitance C based on formula (2) becomes large.So the leakage current i based on formula (1) may exceed the value specifying in electrical appliance administrative law.
By clip insulating material 32 between winding 24 and stator core 23, thereby can reduce leakage current i.But in the situation that R32 is used as to cold-producing medium, the insulating material 32 generally using now cannot ensure that leakage current i is less than or equal to the value specifying in electrical appliance administrative law.The thickness of the insulating material 32 generally using is now 3mm to the maximum, and when Thickness Ratio 3mm thick, or during overlapping insulating material 32 2 uses, cost uprises, assembleability variation.
Fig. 6 is the sectional view upwards of week of the T shape portion of stator core and the body of insulator.Winding 24 is wound on the T shape portion 28 of stator core 23 and the body 30 of insulator 26 by reel winder.
In the past, winding 24 was closely connected with the T shape portion 28 of stator core 23.On the other hand, in the present embodiment, as shown in Figure 6, make the circumferential width of body 30 of insulator 26 larger than the circumferential width of the T shape portion 28 of stator core 23.By the winding 24 of reeling on the stator core 23 such and insulator 26, can make winding 24 not contact with stator core 23, can between stator core 23 and winding 24, gap 31 be set.
According to present embodiment, guarantee the distance d between winding 24 and stator core 23 by gap 31, thereby, can reduce the spuious electrostatic capacitance C based on formula (2), and make to be less than or equal to based on the leakage current i of formula (1) value specifying in electrical appliance administrative law.
In addition, the T shape portion 28 of stator core 23 and axial (the gyroaxis direction of axle 6) of the body 30 of insulator 26 from stator core 23, be roughly the same shape beyond circumferential width.But, in order to prevent the deteriorated of winding 24, make the T shape portion 28 from stator core 23 in the body 30 of insulator 26 towards the part of circumferentially stretching out for oval.
And, in gap 31, accumulate R32 and refrigerator oil.By dielectric constant is configured in to the part in gap 31 than R32 and the low insulating material 32 of refrigerator oil, can reduce the mean value of the DIELECTRIC CONSTANT ε in gap 31, can further reduce leakage current i.
And, except the circumferential width of the body 30 that makes insulator 26 is greater than the circumferential width of T shape portion 28 of stator core 23, can also between winding 24 and stator core 23, configure insulating material 32.
And except the circumferential width of the body 30 that makes insulator 26 is greater than the circumferential width of T shape portion 28 of stator core 23, the inner peripheral surface that can also make insulator annulus 29 is further interior side-prominent towards radially than the inner peripheral surface of stator core annulus 27.
As described above, according to present embodiment, strengthen the distance between winding 24 and stator core 23, can obtain the effect that reduces spuious electrostatic capacitance C, reduces leakage current.
(embodiment 2)
For inscape that present embodiment is identical with the 1st execution mode, the description thereof will be omitted.Fig. 7 is the key diagram of the return portion at the two ends of insulating material.Fig. 8 is the sectional view upwards of week of the T shape portion of stator core and the body of insulator.
As shown in Figure 7, the insulating material 32 of present embodiment, the return portion 32a having turned back in the two ends with bearing direction.That is to say, at the two ends of the bearing direction of stator core 23, insulating material 32 turn back and overlapping state under be configured in stator core 23 and winding 24 radially between.
The insulating material 32 of present embodiment is 1, but the return portion 32a that is insulated material 32 due to winding 24 supports, therefore, even be 2 times of thickness of insulating material 32 also making distance d between winding 24 and stator core 23 near central authorities.
According to present embodiment, as shown in Figure 8, except configuration insulating material 32 between winding 24 and stator core 23, can also between stator core 23 and insulating material 32, gap 31 be set.Therefore, by insulating material 32 is turned back and guaranteed the distance d between winding 24 and stator core 23, thereby can reduce the spuious electrostatic capacitance c based on formula (2), reduce the leakage current i based on formula (1).
In addition, in the present embodiment, as shown in Figure 8, more lean on stator core 23 sides although the return portion 32a of insulating material 32 is positioned at than winding 24, also can make the return portion 32a of insulating material 32 be positioned at winding 24 sides.
But in the case of the return portion 32a of insulating material 32 is positioned at winding 24 sides, near central authorities, gap 31 is positioned between winding 24 and insulating material 32.Owing to can accumulating cold-producing medium in gap 31 during this time, so easily from winding 24 towards refrigrant leakage electric current.
On the other hand, in the case of the return portion 32a of insulating material 32 is positioned at stator core 23 sides, as shown in Figure 8, gap 31 is positioned between secured core 23 and insulating material 32.That is, gap 31 joins via insulating material 32 and winding 24, so, can reduce from winding 24 towards the current leakage that is accumulated in the cold-producing medium gap 31.
And, at the two ends of the bearing direction of stator core 23, can guarantee the distance d between winding 24 and stator core 23 by the circumferential thickness of thickening stator core 23.
As described above, according to compressor of the present invention, can strengthen the distance between winding 24 and stator core 23, obtain the effect that reduces spuious electrostatic capacitance C, reduces leakage current.
The invention is not restricted to above-described embodiment, comprise various modified examples.For example, above-described embodiment is the embodiment that intelligibly the present invention is described and be described in detail in order to hold, and needn't possess illustrated whole inscapes.And, the inscape of a part for the inscape of certain embodiment and another embodiment can be replaced, and, the inscape of certain embodiment can be added in the inscape of other embodiment.And, also can append, eliminate, replace other inscape to a part for the inscape of each embodiment.
For example, as compression element 2, except spiral-wound, can also adopt rotator type, swing type or compression element in the form of piston.
And, although to adopting the situation of R32 to be illustrated as cold-producing medium, be not limited to this.For example, as cold-producing medium, also can adopt the mix refrigerant that contains the R32 that exceedes 50 % by weight, maybe need to take other cold-producing medium of leakage current countermeasure.
