Abstract
The utility model relates to a contactor, in particular to a direct current contactor. Heat generated by a coil of the existing direct current contactor passes through cross ventilation, contact conduction and radiation and is diffused out through a coil casing, the radiating effect is poor, and service life of the coil is shortened due to heating. An oil-immersed direct current contactor comprises a coil (1) and a coil casing (2) and is characterized in that an oil-resistant sealing part (5) is arranged between a fixed iron core fixing plate (4) and a contact main body (6), and a space (3) formed by the coil (1) and the coil casing (2) is totally sealed and is filled with transformer oil. The oil-immersed direct current contactor effectively solves the radiating problem of the direct current contactor. Radiating efficiency is improved through oil convection, coil temperature rising is reduced, and coil service life is prolonged.
Description
Technical field
The utility model relates to a kind of contactor, particularly a kind of D.C. contactor.
Background technology
D.C. contactor act as the device that DC power supply (like storage battery) and DC load (like direct current machine) are switched on and off, be a kind of very ripe product.The heat that existing D.C. contactor coil produces is through cross-ventilation, the contact conduction, and radiation through coil housing, distributes heat, and radiating effect is not good, reduces coil useful life owing to generate heat.
The utility model content
Technical problem to be solved:
The heat dissipation problem of D.C. contactor.
Technical scheme:
The utility model provides a kind of oil immersion D.C. contactor; Comprise coil 1 and coil housing 2; It is characterized in that: be provided with oil resistance seal member 5 between static iron core fixed head 4 and the contact main body 6, coil 1 and the space 3 that coil housing 2 forms are sealed fully, be full of transformer oil in the said space 3.
For good sealing effectiveness, said oil resistance seal member 5 is an oil resistant rubber.
For better sealing effectiveness, the said seal member 5 outer fluid sealants that also add
Beneficial effect:
Effectively improved the heat dissipation problem of D.C. contactor.Convection current through oil improves radiating efficiency, reduces coil temperature rise, improves coil useful life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Specify below in conjunction with accompanying drawing.
A kind of oil immersion D.C. contactor; Comprise coil 1 and coil housing 2; It is characterized in that: be provided with oil resistance seal member 5 between static iron core fixed head 4 and the contact main body 6, coil 1 and the space 3 that coil housing 2 forms are sealed fully, be full of transformer oil in the said space 3.
The heat that existing D.C. contactor coil produces is through cross-ventilation, the contact conduction, and radiation through coil housing, distributes heat, but radiating effect is not good, reduces coil useful life owing to generate heat.The utility model provides a kind of scheme that solves said problem, in the space 3 that coil 1 and coil housing 2 form, is full of transformer oil, improves radiating efficiency through the convection current of oil, reduces coil temperature rise, improves coil useful life.In order can transformer oil to be filled in the said space 3, between static iron core fixed head 4 and contact main body 6, be provided with oil resistance seal member 5, make space 3 become complete sealed space.Through test, the D.C. contactor radiating effect of this kind structure is significantly promoted, and during normal use, has reduced the temperature of D.C. contactor, has improved heat dissipation problem, has also prolonged the useful life of coil 1 simultaneously.
For better seal cavity 3, oil resistance seal member 5 is an oil resistant rubber, simultaneously the seal member 5 outer fluid sealants that also add.
Though the utility model with preferred embodiment openly as above; But they are not to be used for limiting the utility model; Anyly be familiar with this art; In spirit that does not break away from the utility model and scope, certainly when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection range of the protection range of the utility model.
Claims (3)
1. oil immersion D.C. contactor; Comprise coil (1) and coil housing (2); It is characterized in that: be provided with oil resistance seal member (5) between static iron core fixed head (4) and the contact main body (6); The space (3) of coil (1) and coil housing (2) formation is sealed fully, and said space is full of transformer oil in (3).
2. a kind of oil immersion D.C. contactor as claimed in claim 1 is characterized in that: said oil resistance seal member (5) is an oil resistant rubber.
3. like claim 1 or described a kind of oil immersion D.C. contactor, it is characterized in that: the outer fluid sealant that also adds of seal member (5).
