Description
Technical field
The utility model relates to a kind of double power supply automatic switching switch field, and more particularly, it relates to a kind of heat radiating type contact of double power supply automatic switching switch.
Background technology
Produce that contain in the medium that the basic reason of electric arc is around device for switching contact itself and contact in a large number can by the electronics dissociated, enough large applied voltage is there is when between the contact of disjunction, and circuital current is when also reaching most your pupil's arc current, will strongly dissociates and form electric arc.
In power industry, device for switching can produce electric arc, because its temperatures as high several thousand degrees celsius, can burn out contact, even cause contact melting welding.Particularly at the contact of double power supply automatic switching switch, determine the performance and used life of whole device for switching in its security performance and useful life, if electric arc does not extinguish immediately, just may burn operating personnel, burning apparatus, even lead to fire, therefore, various arc-control device is adopted in prior art, effectively solve arc extinguishing problem, arc-control device solves the problem extinguished after electric arc produces, but the energy that electric arc produces can't disappear in time, these energy are based on heat, and main concentrating acts on contact, so, for contact itself, still there is two problems: 1. electric arc conductivity is strong, concentration of energy, temperature is high, after producing electric arc, contact is first " victim ", first the heat energy produced act on contact, so contact is exactly a high temperature energy source, arc-control device is in time by arc extinction, and the contact very first time itself is not dispelled the heat, therefore need to be optimized design to structure of contact terminal, can dispel the heat, improve the life-span of contact, 2. the inevitable outcome after electric arc generation is the energy producing high concentration, and the infringement for contact is fatal, needs to be shifted from contact by heat timely or dispel the heat to contact.
Current national patent publication number CN203398057U discloses a kind of heat radiation anti-arc moving contact of circuit breaker, include one group of strips of conductive plate be arranged in parallel, described strips of conductive plate upper and lower end turns down formation trench structure laterally, the bottom land of described trench structure is distributed with multiple insulating mounting backing plate, described insulating mounting backing plate is provided with the heating panel be embedded in trench structure, and described heating panel is provided with the radiating fin of lattice-shaped array distribution.Although this contact can play the effect of heat radiation, also have the effect of arc extinguishing simultaneously, just guided to by electric arc on radiating fin, like this electric arc will damage the contact of radiating fin one end; Secondly, the insulating mounting backing plate of this contact is provided with the heating panel be embedded in trench structure, and such radiating rate is not good; Finally, this contact limits and uses is moving contact, does not possess versatility.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the heat radiating type contact providing a kind of double power supply automatic switching switch, can dispel the heat to the contact of twin-power switch fast and effectively, improve the useful life of contact, ensure the security performance of double power supply automatic switching switch.
For achieving the above object, the utility model provides following technical scheme: a kind of heat radiating type contact of double power supply automatic switching switch, comprise contact body, insulating heat-conductive part and heating panel, it is characterized in that: described contact body comprises contact jaw and radiating end, described radiating end is flute profile cavity, described insulating heat-conductive part is fixedly installed on grooved cavity inner wall, and described heating panel is arranged on to conflict in grooved cavity and with insulating heat-conductive part and is connected, and described heating panel is provided with radiating part.
By adopting technique scheme, due to the heat of electric arc generation in contact body, through being arranged on the insulating heat-conductive part of radiating end, because insulating heat-conductive part has the performance of extremely strong heat by conduction, heat can be transferred to rapidly on the radiating part on heating panel, reach the object that contact is dispelled the heat rapidly, thus protection contact, improve contact life-span and security performance; Insulating heat-conductive part is by contact body and radiating plate insulation, thus electric arc can not be introduced to radiating end, avoids electric arc and damages radiating end; By the design of above scheme to the structure of contact terminal of double power supply automatic switching switch, dispel the heat for contact itself, solve the problem of dispelling the heat rapidly after contact produces heat.
The utility model is set to further: described contact jaw arranges some thermal holes, and described thermal hole is connected with insulating heat-conductive part.
By adopting technique scheme, the heat that contact place produces can disperse in time, and is delivered on insulating heat-conductive part by thermal hole rapidly, the radiating effect of the contact strengthened further.
The utility model is set to further: described radiating part comprises fin and heat radiation gap, and described fin is square thin slice, and described radiation fin array is distributed on heating panel, and the space between every abutting fins is heat radiation gap.
By adopting technique scheme, the heat dispersion of contact all can be improved in the heat radiation gap between the distribution mode of fin and fin.
The utility model is set to further: described insulating heat-conductive part is made up of heat conductive silica gel, described heating panel and radiating part one-body molded.
By adopting technique scheme, heat conductive silica gel has extremely strong heat conductivility, can improve the conduction of velocity of heat, and radiating part and heating panel are wholely set, and enhances heat conduction performance, improves radiating effect.
The utility model is set to further: described grooved cavity hatch width is greater than slot bottom width.
By adopting technique scheme, the heat-dissipating space that can improve radiating end further increases the heat dispersion of contact.
