Description

Technical Field

[0002] At present, most of the domestic outdoor high-voltage vacuum circuit breakers use sealed vacuum interrupter and related conductors. After the vacuum interrupter is fixed in the existing sealed pole, one sealed pole corresponds to one vacuum interrupter and related conductor. The model parameters and dimensions of the vacuum interrupter are fixed. If you need to replace the vacuum interrupter and related conductors of different sizes, you need to design another sealed pole, which causes a waste of cost.

[0045] Example 1

[0046] This embodiment provides a primary and secondary deep fusion solid-sealed pole, as shown in the attached Figure 1-7 As shown, including:

[0047] The body 11 is cast with a mutual inductor 12, a first conductive part 13, an upper lead 14 and a lower lead 15. Here, casting specifically refers to placing the mutual inductor 12, the first conductive part 13, the upper lead 14 and the lower lead 15 in a mold. Through casting, the four parts of the mutual inductor 12, the first conductive part 13, the upper lead 14 and the lower lead 15 are integrally formed with the body 11, that is, the mutual inductor 12, the first conductive part 13, the upper lead 14, the lower lead 15 and the body 11 form a whole. It should also be noted here that the mutual inductor 12 is electrically connected to one end of the first conductive part 13 before casting, and then placed in the mold. The upper lead 14 and the lower lead 15 are independently arranged, and there is no electrical connection between the two. After casting, the mutual inductor 12 is entirely contained in the body 11, and only the first conductive member 13 is used to transmit signals to the outside. Most of the upper lead 14 and the lower lead 15 are located in the body 11, forming insulation between each other. Only part of the upper lead 14 and the lower lead 15 are exposed in the first cavity 111 and the second cavity 112. The upper lead 14 and the lower lead 15 will not extend to the outside of the body 11. The body 11 forms insulation from the upper lead 14 and the lower lead 15 to the outside of the body 11. The body 11 is provided with a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 are independently arranged, and the space sizes of the two are different. The first chamber 111 is provided with an upper opening 1111, a side opening 1112 and a first lower opening 1113. The upper opening 1111 is an upper opening toward the main body 11, and the upper opening 1111 is connected to the first chamber 111. It should be noted here that the upper part of the main body 11 is the incoming line position. The side opening 1112 is located on the side of the main body 11, and the side opening 1112 is connected to the first chamber 111. The side opening 1112 can select a suitable position according to actual needs. In this embodiment, the connecting channel between the side opening 1112 and the first chamber 111 is horizontally arranged. The side of the main body 11 is the outgoing line position, forming an output effect. The first lower opening 1113 is an opening toward the bottom of the main body 11, and the first lower opening 1113 is used for the installation of the assembly module. At the same time, the lower end of the main body 11 is used to cooperate with the controller 16 to form a sealing effect of the first lower opening 1113. It can be an assembly of one controller 16 for one sealed pole, or two sealed poles and one controller 16, or three sealed poles and one controller 16. The controller 16 forms an effect of closing the first lower opening 1113 and the second lower opening 1121. At the same time, an operating mechanism is also provided in the controller 16, and the operating mechanism can control the action of the pull rod assembly to realize the connection or disconnection of the moving contact and the static contact of the vacuum arc chamber. This is a prior art, so it is not described in detail in this embodiment.One end of the first conductive member 13 is connected to the mutual inductor 12, the upper end of the first conductive member 13 is electrically connected to the mutual inductor 12, and the lower end of the first conductive member 13 extends downward, where the extension direction is vertically downward. It should be noted that the first conductive member 13 is integrally cast in the body 11, and only the bottom surface of the first conductive member 13 is exposed to the outside, and external components can form a signal transmission effect through the bottom surface of the first conductive member 13. The upper lead 14 is provided with a first through hole 141 connected to the upper opening 1111, and the first through hole 141 and the upper opening 1111 are coaxially arranged. The lower lead 15 is provided with a second through hole 151 connected to the side opening 1112, where the second through hole 151 and the side opening 1112 are also coaxially arranged. The second chamber 112 is provided with a second lower opening 1121, and the second lower opening 1121 is downwardly opened, where the second lower opening 1121 is also closed by the controller 16. The upper lead 14 is provided with a first connection portion 142 , and the first connection portion 142 extends to the second cavity 112 . The lower lead 15 is provided with a second connection portion 152 , and the second connection portion 152 extends to the second cavity 112 .

[0048] The assembly module is accommodated in the first chamber 111. After the assembly module is assembled externally, the entire assembly module is matched with the body 11 to form a connection and fixation effect. The assembly module includes a vacuum arc chamber 17, an upper conductive rod 18, a tie rod assembly 19 and a connection assembly. One end of the upper conductive rod 18 is connected to the static end of the vacuum arc chamber 17, and the other end of the upper conductive rod 18 extends to the outside of the body 11 through the first through hole 141 and the upper opening 1111. Here, the upper conductive rod 18 is electrically connected to the upper lead 14. The tie rod assembly 19 is linked with the moving end of the vacuum arc chamber 17, and the lower end of the tie rod assembly 19 cooperates with the operating mechanism in the controller 16 to form a linkage effect. In this embodiment, the lower end of the tie rod assembly 19 extends downward through the first lower opening 1113, and the lower end of the tie rod assembly 19 extends into the controller 16. The connection component includes a soft connection 20, one end of which is connected to the moving end of the vacuum arc chamber 17. The soft connection 20 forms an electrical connection effect between the incoming line end and the outgoing line end. Since the moving end of the vacuum arc chamber 17 is movable, the stability of the electrical connection is improved by the soft connection 20. Here, the soft connection 20 can be a soft copper wire or a soft copper braided wire or a conductive wire, etc. Since the assembly module is an external assembly, it is detachably arranged relative to the main body 11. Therefore, during assembly, vacuum arc chambers 17 of different specifications and models can be selected for assembly according to customer needs. It is only necessary to ensure that the first chamber 111 can accommodate the assembly module. The assembly module and the main body 11 form two modules, and then the two modules are assembled to form an overall assembly, making the assembly simpler and more convenient.

[0049] The upper wiring terminal 21 is connected to the portion of the upper conductive rod 18 extending outside the body 11. Here, the upper ends of the upper wiring terminal 21 and the upper conductive rod 18 can be threaded or connected in other ways to form an electrical connection and a fixing effect between the upper wiring terminal 21 and the upper conductive rod 18. Due to the existence of the upper wiring terminal 21, the upper conductive rod 18 will not fall downward under the action of gravity, forming a fixing effect between the assembly module and the body 11.

[0050] The lower conductive rod 22 is located on the side of the body 11. The lower conductive rod 22 passes through the side opening 1112 and the second through hole 151 to connect with the connecting assembly. At this time, the lower conductive rod 22 forms an electrical connection effect with the moving end of the vacuum arc chamber 17, and at the same time, the lower conductive rod 22 also forms an electrical connection effect with the lower lead 15. The fixed lower conductive rod 22 passes through the mutual inductor 12, that is, the mutual inductor 12 can detect the current flowing into the lower conductive rod 22. In this embodiment, the mutual inductor 12 is specifically a current mutual inductor 12. It should be noted that part of the lower conductive rod 22 is also exposed on the outside of the body 11 for outlet, and forms an electrical connection with the external wire.

[0051] Voltage sensor 23, the number of voltage sensors 23 is at least two, the voltage sensor 23 is accommodated in the second chamber 112, and the two voltage sensors 23 are respectively connected to the first connection part 142 and the second connection part 152, that is, one of the voltage sensors 23 is electrically connected to the first connection part 142, and the other voltage sensor 23 is electrically connected to the second connection part 152. Therefore, in this embodiment, two sets of circuits are formed, the upper conductive rod 18 forms a circuit through the upper lead 14 and one of the voltage sensors 23, which is used for signal collection or power extraction effect; the lower conductive rod 22 forms another circuit through the lower lead 15 and another voltage sensor 23, which is used for signal collection or power extraction effect, forming an intelligent control effect. It should also be noted that the bottom surface of the voltage sensor 23 is exposed, and the outside can form an electrical connection effect through the bottom surface of the voltage sensor 23. Moreover, since the voltage sensor 23 and the second chamber 112 are also detachably installed, the voltage sensor 23 can also select different specifications according to actual needs, so as to realize the combination of voltage sensors 23 of different specifications and vacuum arc chambers 17 of different specifications. With this structural setting, the mutual inductor 12, the first conductive part 13, the upper lead 14 and the lower lead 15 are cast to form an integral molding with the main body 11, and then the assembly module is installed as a whole from the first lower opening 1113 into the first chamber 111, and the upper end of the assembly module is fixed by connecting the upper terminal 21 with the upper conductive rod 18, and then the lower conductive rod 22 is extended from the side to the first chamber 111 to form a match between the lower conductive rod 22 and the moving end of the vacuum arc chamber 17; the voltage sensor 23 enters the second chamber 112 through the second lower opening 1121 to form an electrical connection with the first connecting part 142 and the second connecting part 152. At this time, the upper conductive rod 18 forms a circuit through the upper lead 14 and one of the voltage sensors 23 for signal collection or power supply; the lower conductive rod 22 forms another circuit through the lower lead 15 and another voltage sensor 23 for signal collection or power supply. The advantage of this structure is that the vacuum interrupter 17 and the voltage sensor 23 can be adjusted according to actual needs. Vacuum interrupters 17 of different specifications and voltage sensors 23 of different specifications can form a combination of various states to meet various needs in the market, and then the function of the entire sealed pole can be realized through assembly. In addition, the voltage sensor 23 is built-in to replace external PT and other parts, achieving integration and intelligent effects.

[0052] Specifically, as attached Figure 1-4As shown, the connection assembly also includes a conductive clip 24 and a second conductive member 25. The conductive clip 24 is sleeved on the moving end of the vacuum arc chamber 17. The conductive clip 24 forms an electrical connection effect with the moving end of the vacuum arc chamber 17. Here, the conductive clip 24 forms a clamping effect, and then is connected and fixed by bolts. One end of the flexible connection 20 is connected to the conductive clip 24, and the connection and fixing method between the flexible connection 20 and the conductive clip 24 is also a bolt connection. In this embodiment, the bolts between the flexible connection 20 and the conductive clip 24 and the bolts for clamping and fixing the conductive clip 24 itself are common bolts. The other end of the flexible connection 20 is connected to the second conductive member 25, and the other end of the flexible connection 20 is also connected to the second conductive member 25 by bolts. The lower conductive rod 22 passes through the side opening 1112 and the second through hole 151 to connect with the second conductive member 25. The connection assembly forms an electrical connection effect through the cooperation of the conductive clip 24 and the second conductive member 25. The conductive clip 24 is sleeved on the moving end of the vacuum arc chamber 17, and the space left is conducive to the linkage between the pull rod assembly 19 and the moving end of the vacuum arc chamber 17, thereby improving the stability of the linkage. Secondly, the convenience of assembling the lower conductive rod 22 is improved by connecting the lower conductive rod 22 with the second conductive member 25. In addition, the moving end of the vacuum arc chamber 17 and the lower conductive rod 22 can also be directly connected through the soft connection 20, but during assembly, the operator needs to go deep into the first chamber 111 to assemble. Since the space of the first chamber 111 is limited, the convenience of operation is low.

[0053] Specifically, as attached Figure 1-6 As shown, the inner wall of the first chamber 111 is provided with a positioning groove 1114, and the second conductive member 25 is accommodated in the positioning groove 1114. The setting of the positioning groove 1114 enables the assembly module to form a positioning and fixing effect after being matched with the first chamber 111, and also facilitates the lower conductive rod 22 to extend to the positioning groove 1114 and be electrically connected to the second conductive member 25. In this embodiment, the second conductive member 25 is partially embedded in the positioning groove 1114 to form a positioning and fixing effect. Here, the second conductive member 25 can also be interference fit with the positioning groove 1114.

[0054] Specifically, as attached Figure 1-6As shown, the lower lead 15 is provided with a second conductive part 153, and the second through hole 151 is arranged on the second conductive part 153. The second conductive part 153 is located at the bottom surface of the positioning groove 1114, where the bottom surface of the positioning groove 1114 is specifically the surface of the positioning groove 1114 close to the side opening 1112, forming a bare effect of the second conductive part 153 toward the first chamber 111, and the second conductive part 153 is fitted with the second conductive member 25. The second conductive part 153 is fitted with the second conductive member 25, increasing the contact area between the second conductive part 153 and the second conductive member 25, and improving the stability of the electrical connection. Secondly, the second conductive part 153 also plays a role of limiting and fixing, preventing the lower conductive rod 22 from excessively extending into the first chamber 111, and ensuring that the length of the lower conductive rod 22 of each product outside the body 11 is consistent. The specific reason is that the lower lead 15 is cast and fixed to the body 11 as a whole, so that the lower lead 15 will not move, thereby ensuring the strength of the second conductive part 153.

[0055] Specifically, the lower conductive rod 22 is threadedly connected or plug-in-connected with the second conductive member 25. The threaded connection or plug-in connection makes it easier to install the lower conductive rod 22. For example, the lower conductive rod 22 is threadedly connected with the second conductive member 25, the lower conductive rod 22 is provided with an external thread, and the second conductive member 25 is provided with a screw hole. After the threaded end of the lower conductive rod 22 passes through the second through hole 151 and matches with the screw hole of the second conductive member 25, the lower conductive rod 22 is rotated. Under the action of the thread, due to the limitation of the second conductive member 25, the second conductive member 25 will move toward the second conductive part 153, so that the second conductive member 25 and the second conductive part 153 are firmly fitted, forming a connection and fixing between the two and ensuring the stability of the electrical connection. In addition, when the thread in the initial position is not engaged, the threaded end of the lower conductive rod 22 can also be matched with the screw hole of the second conductive member 25 by gravity or manual operation or tools. At this time, the second conductive member 25 is partially embedded in the positioning groove 1114 and fits firmly with the second conductive part 153. The entire assembly module forms a connection and fixing effect between the assembly module and the body 11 through the upper conductive rod 18 at the upper end and the upper terminal 21, and the lower conductive rod 22 and the second conductive member 25. At this time, the assembly module will not be separated from the body 11, and after the assembly is completed, the basic installation effect of the sealed pole is formed, that is, the electrical connection effect between the upper conductive rod 18, the vacuum arc chamber 17, and the lower conductive rod 22. Then, through the action of the pull rod assembly 19, the contact structure in the vacuum arc chamber 17 can be separated or connected to form a closing and opening effect. After the second conductive member 25 is fixed, when the pull rod assembly 19 moves, since the second conductive member 25 is fixed, only the soft connection 20 is deformed at this time, and the force generated by the soft connection 20 will not affect the lower conductive rod 22, thereby improving the overall connection stability.

[0056] Specifically, as attached Figure 7As shown, the lower conductive rod 22 is provided with a second stepped groove 221, and the second stepped groove 221 is fitted with the second through hole 151. In this embodiment, the size of the second through hole 151 is smaller than the size of the side opening 1112, and the size here specifically refers to the diameter of the two. The second stepped groove 221 forms a further limit fixation to prevent the lower conductive rod 22 from excessive movement.

[0057] Specifically, as attached Figure 1-6 As shown, the upper lead 14 is provided with a first conductive portion 143, and the first conductive portion 143 is located on the inner wall of the first chamber 111.

Here, the upper conductive rod 18 is also provided with a first stepped groove 181, and the first stepped groove 181 cooperates with the first through hole 141, so that the first conductive portion 143 is partially fitted with the first stepped groove 181 of the upper conductive rod 18. The provision of the first conductive portion 143 increases the contact area between the upper conductive rod 18 and the first conductive portion 143, and improves the electrical connection stability between the two. Secondly, the first conductive portion 143 also forms a limiting and fixing effect, so that the length of the portion of the upper conductive rod 18 extending outside the body 11 is consistent. In this embodiment, the size of the first through hole 141 is smaller than the size of the upper opening 1111, and the size here specifically refers to the diameter of the two.

[0058] Specifically, the rod assembly 19 also includes a screw 191. The bottom surface of the moving end of the vacuum interrupter 17 is open. One end of the screw 191 passes through the bottom surface of the moving end of the vacuum interrupter 17 to realize linkage with the moving end of the vacuum interrupter 17. The other end of the screw 191 is linked with the remaining components of the rod assembly 19 to form a linkage effect. When the operating mechanism in the controller 16 is activated, the moving end of the vacuum interrupter 17 can be driven to move through the rod assembly 19.

[0059] Specifically, as attached Figure 1-6 As shown, the second chamber 112 is provided with a partition 1122, and the partition 1122 separates the second chamber 112 into two cavities, where the partition 1122 extends vertically downward, and the two cavities are independently arranged. The partition 1122 separates the voltage sensor 23. When there are two voltage sensors 23, one of the voltage sensors 23 is electrically connected to the upper lead 14, and the other voltage sensor 23 is electrically connected to the lower lead 15. In order to prevent creepage and improve electrical stability, the two voltage sensors 23 are separated by the partition 1122. In this embodiment, the partition 1122 can be integrally cast, or the partition 1122 can be an independent component, and a separation effect is formed by cooperating with the second chamber 112.

[0060] Specifically, the connection between the first connection part 142 and the voltage sensor 23 can be a threaded connection or a plug-in connection.

The plug-in connection is specifically that the one end of the voltage sensor 23 that cooperates with the first connection part 142 is provided with a clamping groove, and the first connection part 142 is inserted into the clamping groove to form an electrical connection effect. In addition, magnetic attraction can also be used to form an electrical connection effect, that is, one end of the voltage sensor 23 is provided with a magnet, and the magnet is attracted to the first connection part 142; or the first connection part 142 is provided with a magnet, and the first connection part 142 is attracted to one end of the voltage sensor 23; or the first connection part 142 and one end of the voltage sensor 23 are both provided with magnets to form attraction and achieve an electrical connection effect. The connection between the second connection part 152 and the voltage sensor 23 can be a threaded connection, a plug-in connection, or a magnetic attraction connection. The connection mode of the voltage sensor 23 can be adjusted according to actual needs to form a quick installation effect, and this connection mode also has the effect of facilitating replacement. It should also be noted here that the bottom surface of the voltage sensor 23 is also provided with a related connection structure, which can be a thread, a clamping groove, or a magnet, and those skilled in the art can adjust it according to actual needs.

[0061] Specifically, there are four voltage sensors 23, which are arranged in pairs, that is, two voltage sensors 23 in the same group are connected to the first connection part 142, that is, the first connection part 142 is an inverted U-shape, and has two pins at the lower end, which can cooperate with the two voltage sensors 23. Another group of voltage sensors 23 is connected to the second connection part 152, which is also an inverted U-shape, and has two pins at the lower end, which can cooperate with the two voltage sensors 23.

[0062] Specifically, the voltage sensor 23 can be one of a thin film capacitor, an annular ceramic capacitor, a cylindrical ceramic capacitor, or a strip ceramic capacitor, or a combination of two or more thereof. The voltage sensor 23 can be different capacitors, or a combination of multiple types, to achieve different sampling and measurement, power extraction, voltage reduction and other effects, improve intelligent control, and eliminate external PT and other parts, forming an intelligent effect of a single sealed pole.

[0063] Specifically, the body 11 includes an epoxy resin layer 113 and a silicone rubber layer 114, and the silicone rubber layer 114 is located outside the epoxy resin layer 113. The setting of the epoxy resin and silicone rubber layer 114 improves the insulation level of the entire sealed pole. In this embodiment, the silicone rubber layer 114 is molded by covering the silicone rubber, and the epoxy resin layer 113 is molded by pouring epoxy resin, forming a composite insulation effect.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
