The utility model discloses compare in prior art's beneficial effect and lie in, one row of comparing that positive electrode and negative electrode constitute exchanges electrode W, interchange electrode V and interchange electrode U and constitute is the convenient wiring of echelonment, because the echelonment design makes the shell installation hole site of installing at more central point and puts outstanding, shell simple to operate simultaneously.
A fuse is arranged between the first positive electrode and the second positive electrode, and if the current is reversed, the fuse is automatically fused, so that the safety performance is improved.
Description of the drawings:
fig. 1 is the schematic view of the whole structure of the rectifier bridge of the present invention.
The structure comprises a negative electrode 1, a first positive electrode 2, a shell mounting hole position 3, an alternating current electrode W4, a first baffle 5, an alternating current electrode V6, a second baffle 7, an alternating current electrode U8, a second positive electrode 9, a reserved hole position 10 and a fuse 11.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the three-phase rectifier bridge of the present invention,
a rectifier bridge with a safety device comprises an alternating current electrode W4, an alternating current electrode V6, an alternating current electrode U8, a positive electrode and a negative electrode 1, wherein the alternating current electrode W4, the alternating current electrode V6 and the alternating current electrode U8 form a row, the positive electrode and the negative electrode 1 form a row, and the row formed by the positive electrode and the negative electrode 1 is lower than the row formed by the alternating current electrode W4, the alternating current electrode V6 and the alternating current electrode U8 and is in a step shape; the case mounting hole site 3 is provided between a row of the positive and negative electrodes 1 and a row of the alternating current electrode W4, the alternating current electrode V6, and the alternating current electrode U8.
The positive electrode is composed of a first positive electrode 2 and a second positive electrode 9, and a fuse 11 is arranged between the first positive electrode 2 and the second positive electrode 9.
The positive electrode 1 and the negative electrode 1 are arranged at two sides of the opposite alternating current electrode W4, the alternating current electrode V6 and the alternating current electrode U8, so that the positive electrode 1 and the negative electrode 1 can be led out at two sides. Therefore, the positive electrode and the negative electrode 1 can be led out from two sides more conveniently, and the wires can be led out from the middle before, so that the structure is crowded and the heat dissipation performance is poor.
A first baffle 5 is arranged between the alternating current electrode W4 and the alternating current electrode V6, and a second baffle 7 is arranged between the alternating current electrode U8 and the alternating current electrode V6, so that the line crossing is avoided, and the safety performance is improved.
The reserved hole sites 10 are also respectively arranged on two sides of a row formed by the alternating current electrode W4, the alternating current electrode V6 and the alternating current electrode U8. And further space for improving the product is provided.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
