Description
Technical field
It the utility model is related to a kind of vacuum circuit breaker.
Background technology
At present, in circuit breaker is minimized, breaker structure is compact, narrow space, and radiating is bad, and contact arm position is very
The difficult requirement for meeting temperature rise and insulation simultaneously.Minimize conduction and the main load of radiating of the contact arm as breaker in breaker
Body is, it is necessary to more effectively distribute heat caused by galvanic circle, and original contact arm position insulation sleeve is contact arm bag
It is trapped among the space of a relative closure, it is impossible to produce effective cross-ventilation, caused heat is distributed in time.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of be improved to insulation sleeve so that heat
The vacuum circuit breaker for the raising heat dispersion that can be distributed in time.
The technical scheme in the invention for solving the technical problem is：
A kind of vacuum circuit breaker for improving heat dispersion, including breaker body, the pole for connecting breaker body, connection
The contact arm of pole leading-out terminal, the contact for connecting contact arm, it is characterised in that：Insulation sleeve is arranged with described contact arm, described is exhausted
The internal diameter of edge set is more than the external diameter of contact arm.
Preferably, insulation sleeve inner surface is convexly equipped with boss.
Preferably, insulation sleeve include insulation sleeve body, one end of insulation sleeve body is integrally extended with first end,
One end is set on pole leading-out terminal, and the internal diameter of described first end is more than the external diameter of pole leading-out terminal.
Preferably, the other end of insulation sleeve body is integrally extended with the second end, described the second end is set in tactile
On cephalic par, the internal diameter of described the second end is more than the external diameter of contact end.
Preferably, the internal diameter of first end, the second end is more than the internal diameter of insulation sleeve body, described boss circumference point
Cloth is arranged on the inner surface of insulation sleeve body.
The internal diameter of insulation sleeve is more than the external diameter of contact arm, i.e., is provided with gap between insulation sleeve and contact arm, and gap can allow gas
Stream passes through, and is effectively taken out of heat in the form of cross-ventilation in contact arm adstante febre.Insulation sleeve includes insulation sleeve main body and divided
The first end and the second end not being extended integrally to both ends, first end are set on pole leading-out terminal, the second end
It is set in contact end, it is met the requirement of insulation, and first end, the second end and pole leading-out terminal, contact end
Between be also equipped with gap, facilitate heat to distribute.It is circumferential in insulation sleeve body internal surface to have boss respectively, both meet that support is exhausted
Edge covers intensity requirement, and does not influence the convection current of contact arm and the inner room air that insulate.
The beneficial effects of the utility model are：The utility model realizes contact arm and insulation by the improvement to insulation sleeve
Gap setting between set, facilitate cross-ventilation, accelerated heat sheds, and improves the heat dispersion of breaker.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 part mplifying structure schematic diagram.
Fig. 3 is the structural representation of insulation sleeve.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, 2, 3, a kind of vacuum circuit breaker for improving heat dispersion, including breaker body, connection breaker
The pole 4 of main body, the contact arm 3 of connecting post leading-out terminal, the contact 1 for connecting contact arm, are arranged with insulation sleeve 2, insulation sleeve on contact arm
Including insulation sleeve body 6, one end of insulation sleeve body is integrally extended with first end 7, and first end is set in pole leading-out terminal
On, the other end of insulation sleeve body is integrally extended with the second end 5, and described the second end is set in contact end.Insulation
The internal diameter for covering body 6 is more than the external diameter of contact arm 3, and the internal diameter of first end 7 is more than the external diameter of pole leading-out terminal, the second end 5
Internal diameter is more than the external diameter of contact end.First end, the second end internal diameter insulation sleeve body 6 internal diameter, insulation sleeve body
Inner surface circle distribution has boss 10.
The internal diameter of insulation sleeve is more than the external diameter of contact arm, i.e., is provided with gap between insulation sleeve and contact arm, and gap can allow gas
Stream passes through, and is effectively taken out of heat in the form of cross-ventilation in contact arm adstante febre.Insulation sleeve includes insulation sleeve main body 6 and divided
The first end 7 and the second end 5 not being extended integrally to both ends, first end are set on pole leading-out terminal, the second end
Portion is set in contact end, it is met the requirement of insulation, and first end, the second end and pole leading-out terminal, contact end
Gap is also equipped between portion, facilitates heat to distribute.It is circumferential in insulation sleeve body internal surface to have boss 10 respectively, both meet to prop up
Insulation sleeve intensity requirement is supportted, and does not influence the convection current of contact arm and the inner room air that insulate.
The utility model realizes gap setting between contact arm and insulation sleeve, facilitates air pair by the improvement to insulation sleeve
Stream, accelerated heat shed, and improve the heat dispersion of breaker.
