DETAILED DESCRIPTION

[0029] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] The embodiment of the present application discloses a primary-secondary integrated pole-mounted circuit breaker.

[0031] The integrated primary and secondary pole-mounted circuit breaker equipment is a pole-mounted circuit breaker equipment that integrates industry-leading electronic voltage sensors, current sensors, electric energy metering modules, high-speed fault transient recording and other advanced technologies in accordance with the latest State Grid standard "Typical Design of Primary and Secondary Power Distribution Equipment". This equipment can achieve the "adaptive comprehensive local automation" function without relying on the distribution automation master station and communication. Through short-circuit / grounding fault detection technology, no-pressure tripping, fault path adaptive delay power closing and other control logic, adaptive multi-branch multi-contact distribution network structure, it can achieve local line selection, regional positioning and isolation of single-phase grounding faults, and achieve isolation of the fault area and restoration of power supply to the non-fault area through two reclosings, so as to better realize distribution automation.

[0032] The integrated primary and secondary pole-mounted circuit breaker equipment is used for the segmentation and communication functions of the 10kv distribution network trunk line; it adopts a fully sealed and fully insulated design, and the circuit breaker body and the three-remote feeder terminal are connected by aviation connectors; all aviation connectors are military-grade accessories, and the cables and aviation plugs are fully sealed, with a very high level of protection; it has the function of calculating active power, reactive power, power factor, frequency and electric energy; it has an adaptive comprehensive local feeder automation function. The equipment has a built-in set of high-precision, wide-range voltage sensors to collect three-phase voltage and zero-sequence voltage to meet the measurement and metering functions of the feeder terminal (FTU); the pole-mounted circuit breaker has a built-in set of high-precision current sensors to collect three-phase current and zero-sequence current to provide current signals for measurement, protection and metering functions.

[0033] The integrated primary and secondary pole-mounted circuit breaker equipment is an outdoor high-voltage power distribution switchgear with a rated voltage of 12kV and three-phase AC 50Hz. The circuit breaker is mainly used to break and close the load current, overload current and short-circuit current in the power system. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises, as well as places where rural power grids need to be frequently operated. Example 1

[0034] Reference Figure 1-Figure 7 A primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body 1, a support assembly 3 is installed under the circuit breaker body 1, and one side of the support assembly 3 is sleeved on a columnar rod 2, and the columnar rod 2 can be a utility pole. The circuit breaker body 1 is installed on the columnar rod 2 or the utility pole through the support assembly 3, so as to realize the installation and use of the circuit breaker body 1.

[0035] Reference Figure 1 The support assembly 3 includes a support plate 31, which is arranged in a horizontal long plate shape and is arranged perpendicularly to the vertical columnar rod 2 at 90 degrees. The support plate 31 is located below the circuit breaker body 1 and is used to carry the circuit breaker body 1 and support the circuit breaker body 1.

[0036] A first support clamp 33 is installed at one end of the support plate 31, and the first support clamp 33 is sleeved on the columnar rod 2. The support plate 31 and the columnar rod 2 are connected and fixed by the first support clamp 33. A plurality of support rods 32 are hinged below the end of the support plate 31 away from the first support clamp 33. The number of support rods 32 is greater than or equal to two. Through the arrangement of the plurality of support rods 32, the support plate 31 is supported. The plurality of support rods 32 are arranged in an inclined shape and are all inclined in the same direction. One end of the support rod 32 is hingedly installed with the support plate 31, and a second support clamp 34 is installed at one end of the support rod 32 away from the support plate 31. The second support clamp 34 is sleeved on the columnar rod 2, and the support rod 32 and the columnar rod 2 are connected and fixed by the second support clamp 34. At the same time, the second support clamp 34 is hinged with the ends of the plurality of support rods 32, and the second support clamp 34 is located below the first support clamp 33. The first support clamp 33 and the second support clamp 34 connect and fix the columnar rod 2, so that the support plate 31, the support rod 32 and the columnar rod 2 are combined to form a plurality of triangular structures. The triangular structure has the characteristic of stability, which greatly improves the stability of the new primary and secondary integrated column-mounted circuit breaker after installation and use on the columnar rod 2, thereby resisting the influence of greater wind speed, earthquake and other natural environmental factors.

[0037] Reference Figure 2 and Figure 3 The inner walls of the first support clamp 33 and the second support clamp 34 are both provided with a plurality of convex anti-skid bumps 36, and the plurality of anti-skid bumps 36 may be evenly distributed or unevenly distributed. The anti-skid bumps 36 are provided to increase the friction between the first support clamp 33, the second support clamp 34 and the columnar rod 2, and further improve the stability of the fixing on the columnar rod 2.

[0038] An anti-skid pad 37 is provided on one side of the first support clamp 33 and the second support clamp 34 close to the columnar rod 2. The anti-skid pad 37 is made of an elastic material with a high surface roughness. The friction between the first support clamp 33, the second support clamp 34 and the columnar rod 2 is improved through the interference connection between the anti-skid pad 37 and the columnar rod 2, the first support clamp 33 or the second support clamp 34, thereby further improving the stability of its fixation on the columnar rod 2.

[0039] A connecting rod 35 is installed at the end of the first support clamp 33, and the installation direction of the connecting rod 35 is consistent with the direction of the columnar rod 2. The end of the connecting rod 35 away from the first support clamp 33 is connected to the second support clamp 34. Through the structural setting of the connecting rod 35, the support rod 32 and the support plate 31 are matched to form a triangular structure between the three. The triangular structure has the characteristic of stability, which greatly improves the stability of the new primary and secondary integrated column-mounted circuit breaker after installation and use on the columnar rod 2, thereby resisting the influence of natural environmental factors such as greater wind speed and earthquake.

[0040] The two clamps are connected by the connecting rod 35. If one of the clamps becomes loose, the operator will have to climb up to replace or repair it. On the one hand, it involves the need to ensure the safety of the personnel, and on the other hand, it involves the convenience of maintenance. By providing a connecting rod with a length adjustment function, if one of the clamps becomes loose, the setting of the connecting rod 35 will not cause the clamp to fall or slide downward, thereby causing the installation of the circuit breaker to become loose. The setting of the connecting rod 35 avoids the situation of "falling objects from high altitude". At the same time, the operator will not have the inconvenience of maintenance due to the need to hold the clamps steady. The two clamps can be supported by the connecting rod 35, which is equivalent to positioning, making it convenient for the operator to perform maintenance on this basis. Furthermore, the length of the connecting rod 35 has an adjustment function and is linked to the support rod 33. After the length of the support rod 33 is changed, the distance between the two clamps will inevitably change, because the length of the connecting rod 35 is adjusted to match the length of the support rod 33.

[0041] Reference Figure 4 and Figure 5 The connecting rod 35 is a threaded rod connection structure or a spring connection structure. After the installation workers fix the first support clamp 33 and the second support clamp 34 during the installation process, they can rotate the threaded rod or stretch the spring to appropriately adjust the length of the connecting rod 35, thereby reducing the difficulty during the installation process and increasing the margin during the installation process.

[0042] Similarly, the support rod 32 can also be set as a threaded rod connection structure or a spring connection structure. After the installation construction personnel fix the support plate 31 and the second support clamp 34 during the installation process, they can rotate the threaded rod or stretch the spring to appropriately adjust the length of the support rod 32, thereby reducing the difficulty during the installation process and increasing the margin during the installation process.

[0043] Reference Figure 6 and Figure 7In this embodiment, by setting the support rod 32, the support rod 32 can be adjusted according to different positions during installation when connected to the electric pole. For example, the first support clamp 33 and the second support clamp 34 correspond to the two positions of point a and point b respectively. When the first support clamp 33 and the second support clamp 34 are installed at points ab, the length of the support rod 32 is L. If the installation position of point b is to be changed to point c, the length of the connecting rod 35 will be changed accordingly, and the range of the length L of the corresponding support rod 32 will inevitably change, which is set to L1, that is, the first support clamp 33 and the second support clamp 34 correspond to the installation positions at points ac respectively. If the length of the support rod 32 is fixed, then there is no doubt that the support rod 32 needs to be replaced to adapt to the two positions. In this solution, the support rod 32 with adjustable length is adopted, so that the first support clamp 33 and the second support clamp 34 can be flexibly installed at different positions without replacing the support rod 32.

[0044] A support groove 311 is formed on one side of the support plate 31 close to the circuit breaker body 1. Figure 6 As shown, the shape and size of the support groove 311 are similar to the shape and size of the bottom of the circuit breaker body 1, that is, the support groove 311 is adapted to the bottom of the circuit breaker body 1, and the bottom of the circuit breaker body 1 is placed in the support groove 311. By setting the support groove 311, the bottom of the circuit breaker body 1 is better limited therein, further improving the stability and firmness of its installation on the columnar rod 2.

[0045] A buffer pad 312 is placed in the support groove 311. Figure 6 As shown, the buffer pad 312 is made of an elastic material with a relatively high surface roughness. The buffer pad 312 is placed between the bottom of the circuit breaker body 1 and the support plate 31 , thereby increasing the contact friction between the bottom of the circuit breaker body 1 and the support plate 31 and further increasing the stability of the buffer pad 31 when fixed on the columnar rod 2 .

[0046] A plurality of connecting pieces 11 are fixedly provided on the side wall of the circuit breaker body 1, and the number of the connecting pieces 11 is greater than or equal to two. When the circuit breaker body 1 is placed in the support groove 311, the lower end surface of the connecting piece 11 contacts the upper end surface of the support plate 31, and the plurality of connecting pieces 11 are all connected to the support plate 31 by bolts to fix them on the support plate 31, thereby further improving their stability in being fixed on the support plate 31.

[0047] The implementation principle of the first and second integrated pole-mounted circuit breaker in the embodiment of the present application is:

[0048] The installation construction personnel install the first support clamp 33 and the second support clamp 34 on the columnar rod 2, and adjust the appropriate length of the connecting rod 35 and the support rod 32 to firmly install the support plate 31 on the columnar rod 2. Then the circuit breaker body 1 is connected to the support plate 31 by bolts between the connecting piece 11 and the support plate 31, and the circuit breaker body 1 is installed on the support plate 31. Finally, through the combination of the support plate 31, the plurality of support rods 32 and the columnar rod 2, a plurality of triangular structures are formed. The triangular structure has the characteristics of stability, which greatly improves the stability of the new primary and secondary integrated column-mounted circuit breaker after installation and use on the columnar rod 2, thereby resisting the influence of greater wind speed, earthquake and other natural environmental factors on it; at the same time, through the structural setting of the connecting rod 35, the support rod 32 and the support plate 31 are matched to form a triangular structure between the three, further improving the stability of the new primary and secondary integrated column-mounted circuit breaker after installation and use on the columnar rod 2, thereby resisting the influence of greater wind speed, earthquake and other natural environmental factors on it. Example 2

[0049] The main difference between Example 2 and Example 1 is that the telescopic mechanisms on the support rod and the connecting rod are different. In this embodiment, the telescopic mechanisms on the support rod and the connecting rod are the same, which is different from the spring or threaded connection in Example 1. This embodiment takes the connecting rod as an example for explanation.

[0050] Reference Figure 8 and Fig. 9The connecting rod 35 includes a first rod body 39 and a second rod body 40, wherein the first rod body 39 is connected to the first support clamp 33, and the second rod body 40 is connected to the second support clamp 34. A telescopic mechanism is arranged between the first rod body 39 and the second rod body 40, and the telescopic mechanism includes a lead screw 38, which is arranged horizontally, and an active block 47 is arranged on the lead screw 38. A mounting block 41 is arranged at the end of the lead screw 38, and the lead screw 38 is rotatably connected to the mounting block 41, and a knob 42 is arranged at one end of the lead screw 38 close to the mounting block 41. By rotating the knob 42, the lead screw 38 can be driven to rotate, thereby driving the active block 47 to slide on the lead screw 38; a first adjusting rod 43 and a second adjusting rod 45 are respectively arranged on both sides of the lead screw 38, the first adjusting rod 43 is located above the lead screw 38, and the second adjusting rod 45 is located below the lead screw 38, The first adjusting rod 43 and the second adjusting rod 45 are symmetrically arranged with the screw 38 as the center, and there is an angle between the first adjusting rod 43, the second adjusting rod 45 and the screw 38. The first adjusting rod 43 is provided with a first adjusting block 44 connected to the first rod body 39, the first adjusting rod 43 passes through the first adjusting block 44, and the first adjusting rod 43 can slide in the first adjusting block 44, the second adjusting rod 45 is provided with a second adjusting block 46 connected to the second rod body 40, the second adjusting rod 45 passes through the second adjusting block 46, and slides in the second adjusting block 46, the first adjusting block 44, the second adjusting block 46 and the active block 47 are connected by a linkage rod 48, and the first adjusting rod 43, the second adjusting rod 45 and the screw 38 are connected at one end away from the mounting block 41 by a fixing rod 49, and the screw 38 is rotatably connected to the fixing rod 49.

[0051] When it is necessary to reduce the distance between the first support clamp 33 and the second support clamp 34, the operator turns the knob 42 to drive the screw 38 to rotate, and the positions of the first adjustment block 44, the second adjustment block 46 and the active block 47 remain unchanged. Taking the figure as an example, the screw 38 rotates and moves to the left, driving the first adjustment rod 43 and the second adjustment rod 45 to slide to the left, and as the first adjustment rod 43 and the second adjustment rod 45 slide, the distance between the first adjustment block 44 and the second adjustment block 46 becomes smaller, that is, the distance between the first rod body 39 and the second rod body 40 becomes smaller, thereby changing the distance between the first support clamp 33 and the second support clamp 34.

[0052] When it is necessary to increase the distance between the first support clamp 33 and the second support clamp 34, the operator rotates the knob 42 in the opposite direction, causing the screw 38, the first adjusting rod 43, and the second adjusting rod 45 to move to the right, thereby increasing the distance between the first adjusting block 44 and the second adjusting block 46, thereby achieving the purpose of changing the distance between the first rod body 39 and the second rod body 40, so as to change the distance between the first support clamp 33 and the second support clamp 34.

[0053] By adjusting the connecting rod 35 or the supporting rod 32 through the telescopic mechanism, the adjusted length distance also has a self-locking effect, and the adjusted distance is locked through the cooperation of the lead screw 38 and the active block 47. In this telescopic structure, the force direction of the linkage rod 48 and the thread direction of the lead screw 38 are perpendicular to each other. Even if the force direction of the linkage rod 48 vibrates due to external natural environmental factors such as wind speed and earthquake, it will not affect the movement of the lead screw 38 along the thread direction. While achieving length adjustment, it has better shock resistance and self-locking effect.

[0054] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
