With the intelligent development of power network, to the performance requirement for circuit protecting switch also more and more higher, such as current-carrying is big,
Small volume, temperature rise are low.Especially omnipotent breaker is as part very crucial in electric line, generally in closed form
High current is continually fed under state, the electric current that it is carried is bigger, then the current-carrying part volume of breaker is bigger, then conductive part is distributed
Heat is relatively also than larger.Especially when product is by alternating current, due to the kelvin effect characteristic of electric current, cause the equivalent electric of wire
Resistance increase, heating increase, makes conductor effective area be not fully utilized, thus causes metals resources to waste.For 50Hz's
Industrial-frequency alternating current, conductor is copper, and its skin depth is about 10mm, thicker busbar, more unfavorable for transmission high current.
Therefore in product design, rationally the size and structure of design current－carrying conductor, are brought not with reducing kelvin effect
Good influence, while temperature rise can be reduced again, it appears particularly significant.
The content of the invention：
Technical problem to be solved in the utility model is：Reduce the harmful effect that brings of kelvin effect, while again can be with
Reduce busbar temperature rise.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：It is a kind of energy-saving dynamic
Contact connection row, including contact blade, first be flexible coupling electric conductor, second be flexible coupling electric conductor, the first busbar seat, second conductive
Arrange and silver point is provided with seat, the first busbar and the second busbar, the contact blade, described first is flexible coupling electric conductor and second
The electric conductor that is flexible coupling is fixedly connected on the front and rear sides of the lower end of contact blade side by side vertically, and the first busbar seat, second are led
The rear end of electricity row's both seats is respectively perpendicular to the first be flexible coupling electric conductor, second electric conductor that is flexible coupling and is fixedly connected, and first
Busbar seat, the second busbar seat front end of the two are connected by fastener, first busbar and the second busbar
Be set to structure it is identical and only have front opening semi-annular shape structure, the rear end of first busbar and the second busbar
The front end of the first busbar seat and the second busbar seat is respectively and fixedly installed to, between first busbar and the second busbar
Cooperatively form blind round hole.
Preferably, the semicircular ring wall thickness of first busbar and the second busbar is disposed as 10mm~12mm.
Preferably, being set to fillet structure between the bottom surface and the face of cylinder of the blind round hole.
Preferably, described first electric conductor and second that is flexible coupling is flexible coupling between electric conductor and existed between 0.5mm~1mm
Gap, the gap that there is 0.5mm~1mm between first busbar seat and the second busbar seat, first busbar and the
There is 0.5mm~1mm gap between two busbars.
Compared with prior art, usefulness of the present utility model is：Busbar seat uses upper and lower two rows structure, two
Busbar seat connects welding with soft even electric conductor respectively, and busbar removes the relatively low part of middle utilization rate, makes busbar thinning, this
Sample busbar seat carrying object is integrally fully used, and it is empty that the village hollowing design in the middle part of another aspect busbar increases radiating
Between.Therefore not only the current capacity in movable contact system loop is improved, and also increases heat-dissipating space, with more preferable radiating effect
Really, and then reduce temperature rise, while substantially reducing the unfavorable of kelvin effect again, metal material consumption is saved to a certain degree.And it is double
The electric conductor that is flexible coupling forms parallel circuit loop with upper and lower two rows busbar seat, compared to original be singly flexible coupling electric conductor and list
Busbar seat, the caloric value reduction half of this structure（Formula：Heat Q=I2Rt）, so product temperature rise will be substantially reduced.
