Description
Affiliated technical field
The utility model relates to a kind of protector, particularly relates to a kind of difunctional protector of temperature current that overheated overcurrent that compressor of air conditioner, motor, electrothermal device etc. produce because of unusual operating state is effectively protected that is applied in.
Background technology
At present; to compressor of air conditioner, motor, electrothermal device etc. because of unusual operating state produce overheated, when overcurrent is effectively protected; the difunctional protector of employed temperature current; generally have base, junction pole, fixed contact support, support, bimetal leaf and shell; junction pole is fixed on the base by sintered glass; fixed contact support one end is provided with fixed contact; the other end is fixed on the junction pole; support is fixed on the base; bimetal leaf one end is provided with and the corresponding moving contact of fixed contact, and the other end directly is fixed on the support.When temperature overheating or electric current were excessive, two kinds of metals of bimetal leaf were because coefficient of expansion difference, and deformed, and moving contact and fixed contact are separated and cut off the electricity supply, and reached defencive function.
The protector of this structure because the sensitivity of bimetal leaf is required than higher, so require bimetal leaf thickness to approach, will increase bimetal leaf and the support difficulty when welding like this, sealing-off takes place or leak weldering or the phenomenon of transition weldering through regular meeting.
In addition, in different use occasions, claimed device can shield under different temperature, present protector, and each can only be protected under a kind of temperature conditions of setting, can not regulate temperature.
Moreover in different use occasions, the electric current when claimed device shields can change, present protector, and each can only be protected under a kind of current condition of setting, and the size that adapts to electric current can not change.
Summary of the invention
In order to overcome the deficiency of existing protector, the utility model provides a kind of protector, and this protector can not only effectively be protected overheated, overcurrent delicately, and can regulate the size of the height and the electric current of temperature easily.
The technical scheme that its technical problem that solves the utility model adopts is: the built-in plug-in type protector of a kind of hermetically sealed compressor; have base and shell; shell is fixed on the base; be fixed with fixed contact junction pole and moving contact junction pole by sintered glass on the base; decide the fixed contact support on the fixed contact junction pole together; fixing fixed contact on the fixed contact support; the moving contact junction pole is communicated with bimetal leaf by base and shell; the other end of bimetal leaf be fixed with the fixed contact support on the fixing corresponding moving contact of fixed contact; also be provided with stator between bimetal leaf and shell; one end of stator is welded to connect by iron nail and bimetal leaf transition, and the other end and shell are fixed.
Further: for making protector when the excessive electric current, also can play a protective role, also be provided with fusible link between described base and moving contact junction pole.
The utility model principle is reasonable, and modern design is simple in structure, and is applied widely, and result of use is good, and the life-span is long.
The utility model is the sealed type single phasing protection device product that designs for the needs that satisfy new compressor, and it can be used on the interior compressor of air conditioner of 1～3 horsepower range, also can be used for the commercial motor of working in the high pressure corrosive environment.The utility model is that a kind of specialty is used the protective device in compressor of air conditioner inside; the purpose of its design is to guarantee that compressor of air conditioner all can be effectively protected when overheated, overcurrent; product guarantees that by high-power soldering and sealing, glass sintering technology etc. inner chamber can be hedged off from the outer world fully, effectively prevents the intrusion of the inner fluorine of compressor Lyons gas.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
2. bases among the figure, 3. shell, 4. fixed contact, 5. fixed contact support, 6. sintered glass, 7. bimetal leaf, 8. fixed contact junction pole, 9. iron nail, 10. stator, 11. moving contact junction poles, 12. fusible links.
Embodiment
The built-in plug-in type protector of hermetically sealed compressor as shown in Figure 1; have base 2 and shell 3; shell 3 is fixed on the base 2; be fixed with fixed contact junction pole 8 and moving contact junction pole 11 by sintered glass 6 on the base 2; fixing fixed contact support 5 on the fixed contact junction pole 8; fixing fixed contact 4 on the fixed contact support 5; one end of bimetal leaf 7 be fixed with fixed contact support 5 on fixing fixed contact 4 corresponding moving contacts; 3 on bimetal leaf 7 and shell also are provided with stator 10; one end of stator 10 is welded to connect by iron nail 9 and bimetal leaf 7 transition, and the other end and shell 3 are fixing.11 of described base 2 and moving contact junction poles also are provided with fusible link 12.Because the existence of iron nail 9 makes bimetal leaf 7 more firm with the secure bond of stator 10.Adjust the deflection at stator 10 places of shell 3, just can regulate the distance between moving contact and the fixed contact 4, the protection when also just going for different temperatures.The existence of fusible link 12 makes protector when bigger setting electric current, can disconnect and protects.
This protector is that a kind of temperature automatically replies device; during work; connect with motor coil; electric current leads to for 11 times from fixed contact junction pole 8, fixed contact support 5, fixed contact 4, moving contact, bimetal leaf 7, stator 10, shell 3, base 2, fusible link 12, moving contact junction pole successively; protector changes according to coil temperature and motor current size; the heat transferred that is produced when temperature or electric current increase is to bimetal leaf 7; when reaching the predetermined action desired temperature; bimetal leaf 7 is action rapidly just; the contact is disconnected, cut off circuit.When the temperature of motor coil dropped to the specified reset temperature value of this product, bimetal leaf 7 returned to initial condition again, the moving contact closure, and circuit is conducting again.
