Abstract
The invention relates to the technical field of transformers, in particular to a wiring terminal for a power transformer. The wiring terminal for the power transformer comprises a mounting part and a fixed part, wherein the mounting part is used for being fixedly connected with a line outlet terminal at a low-voltage end of the transformer; the fixed part is used for being fixedly connected to a copper plate of a load output end and comprises a clamping groove for clamping the copper plate; longitudinal or transverse grooves are formed in two inner side walls of the clamping groove; screw holes for fixing the copper plate are arranged in the grooves; the widths of the grooves are not less than the diameters of the screw holes, so that the problem of a high calorific value around bolts due to uneven contact of the inner side walls of the clamping groove and the copper plate can be effectively solved.
Description
Technical field
The present invention relates to transformer technology field, especially a kind of power transformer binding post.
Background technology
Along with China's economic continues healthy high speed development, electricity needs maintains sustained and rapid growth, and transformer is as the visual plant of distribution, plays indispensable effect in power network, and the operation of its stability and safety is directly connected to national economy and people and lives life.
And the important component part of binding post effect transformer, particularly low-pressure end binding post, because its voltage is low, electric current is large, when contact is bad or the area of contact is too little, when load increases, just easily cause binding post caloric value too high, not only easily cause the aging of binding post and copper coin, also the easy sealing to transformer voltage section outlet terminal causes damage, shorten the life-span of transformer, the binding post of present transformer is all much directly be placed in draw-in groove by copper coin, and fixed by screw, during due to screw extruding draw-in groove, the steel plate nearer apart from screw contacts tightr with draw-in groove, copper coin is easily caused to contact uneven with draw-in groove madial wall, when load increases, when electric current increases, be easy to cause caloric value around screw large.
Summary of the invention
The technical problem to be solved in the present invention is: contact uneven with copper coin in order to solve draw-in groove madial wall, easily cause the problem that around screw, caloric value is large, the invention provides a kind of power transformer binding post, by being provided with longitudinal or horizontal groove on draw-in groove two madial wall, the screw being used for fixing copper coin is set in groove, the width of groove is not less than the diameter of screw, effectively solves draw-in groove madial wall and contacts with copper coin uneven, easily cause the problem that caloric value around screw is large.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of power transformer binding post, comprises
Installation portion, described installation portion is used for being fixedly connected with step-down side outlet terminal;
Fixed part, described fixed part is for being fixedly connected with the copper coin of load outputs, described fixed part comprises the draw-in groove for clamping copper coin, described draw-in groove two madial wall is provided with longitudinal or horizontal groove, be provided with the screw for fixing copper coin in described groove, the width of described groove is not less than the diameter of screw.
Particularly, described groove and draw-in groove ft connection, be conducive to the heat radiation of copper coin and fixed part.
Particularly, described draw-in groove two madial wall is that splayed distributes to top by bottom, copper coin is coordinated tightr with draw-in groove, ensures to contact tight.
As preferably, the angle of described draw-in groove two madial wall is less than or equal to 5 degree for being more than or equal to 1 degree.
As preferably, described fixed part is provided with the projection for dispelling the heat, and is conducive to the heat radiation of fixed part.
As preferably, described installation portion is provided with the projection for dispelling the heat, and is conducive to the heat radiation of installation portion.
The invention has the beneficial effects as follows: the invention provides a kind of power transformer binding post, structure is simple, be skillfully constructed, by screwed hole is arranged in groove, effectively can solve draw-in groove madial wall contacts uneven with copper coin, easily cause the problem that around screw, caloric value is large, greatly reduce caloric value, avoid the damage of step-down side binding post sealing, considerably increase the useful life of transformer, ensure that safely and steadily running of network system, thus greatly reduce maintenance cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of a kind of power transformer binding post of the present invention;
Wherein: 1. installation portion; 2. fixed part; 3. draw-in groove; 4. groove; 5. screw; 6. protruding.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment 1
A kind of power transformer binding post, comprise installation portion 1 and fixed part 2, wherein installation portion 1 is for being fixedly connected with step-down side outlet terminal, fixed part 2 is for being fixedly connected with the copper coin of load outputs, fixed part 2 comprises the draw-in groove 3 for clamping copper coin, draw-in groove 3 liang of madial walls are provided with longitudinal or horizontal groove 4, are provided with the screw 5 for fixing copper coin in groove 4, and the width of groove 4 is not less than the diameter of screw 5.
As preferably, groove 4 and draw-in groove 3 ft connection, improve heat radiation.
As preferably, draw-in groove 3 liang of madial walls are that splayed distributes to top by bottom, the angle of draw-in groove 3 liang of madial walls is less than or equal to 5 degree for being more than or equal to 1 degree, in order to ensure copper coin and draw-in groove 3 compact siro spinning technology, general copper coin outline is wider than the width of draw-in groove 3, the plane tilted is convenient to place copper coin, and can ensure that the copper coin be fastened in draw-in groove 3 fully can contact with draw-in groove 3 by screw.
As preferably, fixed part 2 is provided with the projection 6 for dispelling the heat, and installation portion 1 is provided with the projection 6 for dispelling the heat, and improves heat radiation further.
During installation, the installation portion 1 of binding post is connected with step-down side outlet terminal, the copper coin of load outputs is fastened in draw-in groove 3, and by screw in compression draw-in groove 3, draw-in groove 3 is fully contacted with copper coin, because screw 5 is arranged in groove 4, after tightening screw, copper coin is there will not be to contact uneven situation with draw-in groove 3.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
