Abstract
The utility model provides a take self -resuming protection device's transformer, effectively improves product stability and can prolong its life at its simple structure. The utility model discloses a transformer skeleton (1) and cover are established iron core (2) on transformer skeleton (1) still be provided with self -resuming protection device (3) on transformer skeleton (1). It is very sensitive to ambient temperature, electric current through provide one kind to the transformer self -resuming protection device (3) make probably yin wendu sudden change or the current value bigger than normal and lead to the fact the transformer and start the protection action before destroying, reach anticipated protecting effect, improve equipment's reliability and stability. The utility model discloses be applied to transformer preparation field.
Description
Technical field
The utility model relates to a kind of transformer, particularly relates to a kind of transformer with self-recovery protection device.
Background technology
Along with the continuous progress of society, various electrotechnical instrument and meter and electronic equipment obtain and apply more and more widely in routine work and life, and ensure these equipment and instruments safety and reliability in use, be then a very important problem.Electronic transformer, as components and parts very important in electrotechnical instrument and meter, in circuit for providing power supply needed for electronic equipment, has voltage transitions simultaneously, the irreplaceable effects such as isolation.Improve the reliability of transformer, greatly can improve useful life and the stability of the electronic equipments such as instrument and meter.The unusual conditions such as transformer work there will be that overvoltage, ambient temperature are too high often, late-class circuit overload or short circuit; if now unprotect device is protected transformer; likely reducing transformer life even makes transformer lose efficacy; conventional countermeasure increases by a protective circuit in primary; but extra circuit not only increases volume and the cost of whole equipment, and the external reliability of protective circuit is also unsatisfactory.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of structure simple, the effective a kind of transformer with self-recovery protection device improving product stability and extend its useful life.
The technical scheme that the utility model adopts is: the utility model comprises transformer framework and is set in the iron core on described transformer framework, and described transformer framework is also provided with self-recovery protection device.
Further, described self-recovery protection device comprises and being arranged in described transformer framework and the thermistor be connected with any two adjacent wiring pin.
Further, be also coated with one deck transformer case at described transformer framework and described iron core periphery, in the space in described transformer case, be also filled with curing material.
The beneficial effects of the utility model are: comprise transformer framework due to the utility model and be set in the iron core on described transformer framework, described transformer framework is also provided with self-recovery protection device.Compared with prior art, the utility model is by providing a kind of to ambient temperature to transformer, the described self-recovery protection device that electric current is very responsive, make may because of temperature jump or current value bigger than normal and front starting protection action is damaged to transformer, reach the protection effect of expection, the reliability and stability of raising equipment, simultaneously, the PCB of instrument and meter is when assembling, the operation of deduplication plug-in mounting protective device can be economized, save labour cost, decrease the size of equipment, and the described self-recovery protection device of this technology is built in transformer, the high temperature that transformer operation irregularity produces can directly conduct to described self-recovery protection device, thus make it produce action, protection is formed to transformer, make the work of transformer more reliable more accurate, improve reliability and the life-span of whole equipment and instrument.So the utility model structure is simple, effective to be improved product stability and extends its useful life.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the cutaway view of described self-recovery protection device.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises transformer framework 1 and is set in the iron core 2 on described transformer framework 1, and described transformer framework 1 is also provided with self-recovery protection device 3.Described self-recovery protection device 3 comprises and being arranged in described transformer framework 1 and the thermistor 5 be connected with any two adjacent wiring pin 4.In the utility model, described wiring pin 4 is T-shaped wiring pin, before described transformer framework 1 does not also have injection mo(u)lding, after now by the lead-in wire on described thermistor 5, described wiring pin 4 is connected with two respectively, again they are placed on the relevant position of mould, after injection mo(u)lding, described thermistor 5 is just one-body molded with described transformer framework 1.Also be coated with one deck transformer case 6 at described transformer framework 1 and described iron core 2 periphery, in the space in described transformer case 6, be also filled with curing material 7.In the present embodiment, described transformer case 6 can be plastic casing or metal shell; Described curing material 7 is epoxy resin.
When circuit normally works, described thermistor 5 temperature and room temperature is close, resistance value is very little, series connection can not hinder electric current to pass through in circuit; And when there is overcurrent when circuit because fault; described thermistor 5 causes temperature to rise due to heating power increase, and when temperature exceedes switch temperature, resistance can increase severely instantaneously; electric current in loop is reduced to safety value rapidly, plays a protective role to circuit and equipment.Because the designability of described thermistor 5 is good; by change self switch temperature to regulate it to the sensitivity of temperature; thus can play overheat protector and overcurrent protection two kinds effect simultaneously, reach the effect improving stabilization of equipment performance, extension device useful life.
The utility model is applied to transformer and makes field.
Although embodiment of the present utility model describes with practical solution, but the restriction do not formed the utility model implication, for those skilled in the art, according to this specification to the amendment of its embodiment and and the combination of other schemes be all apparent.
Claims (2)
1. the transformer with self-recovery protection device; it comprises transformer framework (1) and is set in the iron core (2) on described transformer framework (1); it is characterized in that: on described transformer framework (1), be also provided with self-recovery protection device (3), described self-recovery protection device (3) comprises and being arranged in described transformer framework (1) and the thermistor (5) be connected with any two adjacent wiring pin (4).
