Abstract
The present invention relates to a kind of heat dissipating method of circuit breaker lap joint, circuit breaker termination is installed the lap joint of a conduction arch shape of a hoof, and the external conductor tab of circuit breaker is connected in described conductive taps.Pass in and out between termination in horseshoe type lap joint and circuit breaker, have the heat-dissipating space that larger, obviously reduce the temperature rise of external joining seam and circuit breaker termination.
Description
Technical field
The present invention relates to technical field of electrotechnical equipment, the heat dissipating method of particularly a kind of circuit breaker lap joint.
Background technology
Existing low-voltage circuit breaker is into and out of holding the bridging method with external connection row, be all the plane of busbar directly and low-voltage circuit breaker directly overlap into and out of termination, securing member is adopted to fix or the solid mode of direct grafting, the mode of this direct overlap joint is when being energized operation, and the heat of the heat that low-voltage circuit breaker termination produces and external busbar lap joint is superimposed and the temperature of low-voltage circuit breaker termination and external connection row lap joint is raised.When the circuit breaker of this overlap joint is arranged in the bin of more than degree of protection IP30, the temperature rise of circuit breaker termination and external connection row lap joint just exceeds standard defective, and temperature rise be made qualified, can only reduce electric current 20% and use below.
And existing solution strengthens cross-sectional area of conductor to amass to accelerate heat radiation, or install forcing functions device additional, increase cross-sectional area of conductor is long-pending causes bin space to diminish, and installs cooling device additional and not only takies bin space, too increase cost.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, a kind of heat dissipating method of circuit breaker lap joint is provided, increasing cross-sectional area of conductor is not being needed to amass to realizing, when not needing to install forcing functions device additional, when circuit breaker is arranged in the bin of more than degree of protection IP30, the temperature rise of circuit breaker termination and external connection row lap joint is stable, qualified.
The technical scheme that the present invention takes is:
A heat dissipating method for circuit breaker lap joint, is characterized in that, a conductive taps is installed in circuit breaker termination, and the external conductor tab of circuit breaker is connected in described conductive taps.
Further, described conductive taps is the shape of a hoof, the base, U-shaped both sides of shape of a hoof lap joint is connected with described circuit breaker termination, the opening of horseshoe type lap joint is towards the outside of circuit breaker termination, and described external conductive contact is fixedly connected on circuit breaker termination by bolt and described water chestnut lap joint.
Further, in the curved side of described shape of a hoof lap joint, have one with the ventilating opening communicated in circuit breaker.
The invention has the beneficial effects as follows:
1, horseshoe type lap joint is a pressing and bending part, can adopt the same material of external busbar, process simple and easy, with low cost.
2, pass in and out between termination in horseshoe type lap joint and circuit breaker, there is the heat-dissipating space that larger, the temperature rise of the external joining seam of obvious reduction and circuit breaker termination, makes that the temperature rise of the external broken end of circuit breaker be arranged in more than IP30 (IP40) case is originally defective reaches qualified requirement.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of circuit breaker of the present invention;
Accompanying drawing 2 is the A-A cutaway views in accompanying drawing 1;
Accompanying drawing 3 is perspective view of horseshoe type lap joint.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the heat dissipating method of circuit breaker lap joint of the present invention.
See accompanying drawing 1, 2, the circuit breaker termination 2 of circuit breaker connector 1 is all provided with the connecting screw hole connecting external conductor tab 4, circuit breaker termination 2 is placed conduction shape of a hoof lap joint 3, the U-shaped side of shape of a hoof lap joint 3 is connected with circuit breaker termination 2, the opening of horseshoe type lap joint 3 is towards the outside of circuit breaker termination 2, external conductive contact 4 strides across shape of a hoof lap joint 3 by bolt and matches with the screw on circuit breaker termination 2, by circuit breaker termination 2, shape of a hoof lap joint 3 and external conductive contact 4 are connected together, shape of a hoof lap joint 3 adopts the mode overlapped with side, circuit breaker termination, make the heat that circuit breaker termination 2 and shape of a hoof lap joint 3 produce, heat major part space in shape of a hoof lap joint 3 that shape of a hoof lap joint 3 and external conductive contact 4 produce leaves, shape of a hoof lap joint 3 increases the area contacted with air, improve radiating effect.
See accompanying drawing 3, in the curved side of shape of a hoof lap joint 3, have a ventilation mouth 5, ventilation mouth 5 communicates with circuit breaker internal.Ventilation mouth 5 is conducive to the flowing of air, accelerates radiating rate.
Because adjacent two joints all adopt shape of a hoof lap joint 3 to dispel the heat, the height arranging two adjacent shape of a hoof lap joints 3 is unequal, makes heat radiation faster.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
