For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] This embodiment provides a conveniently installed primary and secondary integrated pole-mounted circuit breaker. In one implementation, such as... Figures 1 to 6 As shown, it includes a circuit breaker body 1 and a circuit breaker bracket 7. In addition to core functional components such as the vacuum circuit breaker 9, the circuit breaker body 1 generally includes a circuit breaker base 2. Therefore, in the relevant views of this specification, only the circuit breaker base 2 is used to represent the circuit breaker body 1. The circuit breaker bracket 7 generally includes a crossbar 6 for support and a vertical bracket 15 for connection to the utility pole.

[0029] A horizontal guide plate 4 is provided at each of the opposite ends of the bottom surface of the circuit breaker base 2. A triangular groove is formed on the horizontal guide plate 4 by the intersection of two first inclined sides 11. The opening directions of the triangular grooves at both ends are opposite to each other. A first bolt hole 8 is also provided on the horizontal guide plate 4. A support plate 5 is provided at each end of the top surface of the circuit breaker bracket 7, i.e., the crossbar 6. A vertical guide plate 3 is vertically arranged on the support plate 5. The vertical guide plate 3 has a second inclined side 13, which together form a flared opening. The larger end of the flared opening faces away from the support plate 5; the smaller end of the flared opening is the distance between the corners of the triangular grooves at both ends. A second bolt hole 12 is also provided on the support plate 5.

[0030] When the circuit breaker body 1 and the circuit breaker bracket 7 are installed together, the horizontal guide plate 4 and the support plate 5 belonging to the same end are attached to each other, and the roots of the vertical guide plates 3 at both ends are respectively locked at the corner of the triangular groove at the same end, and the first bolt hole 8 and the second bolt hole 12 are aligned.

[0031] As to the method of using the device, when the circuit breaker body 1 is hoisted above the circuit breaker support 7, first, the two ends of the vertical guide plate 3 are roughly aligned with the corresponding triangular grooves, and then the circuit breaker body 1 is dropped. With the falling of the circuit breaker body 1, the top of the vertical guide plate 3 will enter the area of the triangular groove, so it will be constrained by the first inclined edge 11, and the horizontal guide plate 4 will also be constrained by the horn formed by the second inclined edge 13. With the continuous falling of the circuit breaker body 1, the intersection position of the horizontal guide plate 4 and the vertical guide plate 3 migrates from the top to the root of the vertical guide plate 3 when viewed from the side, so the vertical guide plate 3 enters the corner area of the triangular groove with the convergence of the triangular groove, until it reaches the tip of the triangular groove, and is clamped by the abutment of the two first inclined edges 11, finally making the circuit breaker body 1 form positioning in the front-back direction. At the same time, the horizontal guide plate 4 also enters the small end area of the horn with the convergence of the horn, and until the circuit breaker body 1 is clamped at the small end of the horn, so that the circuit breaker body 1 forms positioning in the left-right direction. Through the positioning in the above two directions, strict alignment between the circuit breaker body 1 and the circuit breaker support 7 can be formed, so that the bolt holes of the two are aligned with each other, facilitating subsequent connection operations.

[0032] It can be seen that by setting the horizontal guide plate 4 and the vertical guide plate 3, and setting the triangular groove on the horizontal guide plate 4 and the horn on the vertical guide plate 3, and using the convergence of the triangular groove and the horn during the falling of the circuit breaker body 1, the circuit breaker body 1 and the circuit breaker support 7 can be strictly positioned after rough alignment in the early stage, so that the bolt holes of the two are accurately aligned, facilitating a series of subsequent operations such as bolt insertion and fastening.

[0033] Based on the above embodiment, in a preferred embodiment, as shown in Figure 2 and 4As shown, the corner of the triangular groove is provided with a clamping groove 10, the width of the clamping groove 10 is the same as the width of the vertical guide plate 3, the distance between the groove bottom edges of the clamping grooves 10 at both ends is the distance between the roots of the vertical guide plates 3 at both ends; when the circuit breaker body 1 and the circuit breaker support 7 are installed together, the roots of the vertical guide plates 3 are clamped in the clamping grooves 10. The reason for this arrangement is that the first inclined edge 11 acts as a guiding edge and will often rub against the front side edge of the vertical guide plate 3. After long-term use, as the first inclined edge 11 wears, the corner of the triangular groove tends to expand, and the front side edge of the vertical guide plate 3 also shrinks in size due to wear, so that the vertical guide plate 3 cannot be clamped with the first inclined edges 11 on both sides to form a clamping, thereby causing the circuit breaker body 1 to be positioned inaccurately. After the clamping groove 10 is arranged, the vertical guide plate 3 enters the clamping groove 10 after the triangular groove is narrowed, the clamping groove 10 always maintains appropriate dimensional accuracy because it does not participate in the narrowing and guiding, and the rear side edge of the vertical guide plate 3 that does not participate in the narrowing and rubbing also enters the clamping groove 10 to participate in clamping, so that the problem of reduced positioning accuracy due to wear of the first inclined edge 11 and the front side edge of the vertical guide plate 3 can be avoided.

[0034] Based on the above embodiment, in a preferred embodiment, as shown in Figure 1 and 5 The root of the vertical guide plate 3 is provided with a vertical edge 14, the vertical edge 14 intersects the second inclined edge 13; when the circuit breaker body 1 and the circuit breaker support 7 are installed together, the vertical edge 14 is in close contact with the groove bottom edge of the corresponding clamping groove 10. The reason for this arrangement is that if one side of the vertical guide plate 3 is entirely the second inclined edge 13, then as the second inclined edge 13 participates in guiding and wears, the distance between the roots of the vertical guide plates 3 at both ends will tend to increase, ultimately causing the circuit breaker body 1 to be positioned inaccurately in the left-right direction. By arranging the vertical edge 14, the vertical edge 14 will not wear because it does not participate in the narrowing and guiding, so the dimensional accuracy between the vertical edges 14 on both sides can always be maintained, thereby forming accurate left-right direction positioning after the vertical edge 14 is in close contact with the groove bottom edge of the clamping groove 10 in the final stage of the positioning process.

[0035] Based on the above embodiment, in a preferred embodiment, as shown in Figure 4 The two first inclined edges 11 are symmetrically arranged about the center line of the horizontal guide plate 4; the triangular grooves at both ends are symmetrically arranged about the center line of the circuit breaker body 1. This arrangement can avoid the one-to-one matching relationship between the horizontal guide plates 4 and the supporting plates 5 at both ends, thereby enabling the circuit breaker body 1 to be installed in reverse, and facilitating the construction personnel to select the orientation of the circuit breaker body 1 according to the actual situation on site.

[0036] Based on the above embodiment, in a preferred embodiment, as shown in Figure 4As shown, the included angle a between the two first bevels 11 is 80-100°, preferably 90°. If the included angle a is too small, the triangular groove opening will be reduced, and the rough alignment adaptability in the early stage of installation will be reduced. If the included angle a is too large, the vertical guide plate 3 may be blocked after contacting the first bevel 11 due to excessive friction, and cannot smoothly realize the guiding, reducing the installation fluency. The included angle a of 90° is a preferred value considering both cases.

[0037] Based on the above embodiments, in a preferred embodiment, as shown in Figure 5 The inclination angle β of the second bevel 13 is 40-50°, preferably 45°. The size of the inclination angle β can be analogized to the case of the above included angle a, and the inclination angle β of 45° is a preferred value considering the overall situation.

[0038] Obviously, the above embodiments are only examples for clearly illustrating, and are not limitations to the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
