Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for capacitor couplers, and more specifically to phase-to-phase capacitor coupler devices. Background Technology

[0002] Capacitive couplers are capacitors used to transmit signals in power networks. They are mainly used in power frequency high voltage and ultra-high voltage AC transmission lines to achieve purposes such as carrier wave, communication, measurement, control, protection, and energy extraction. In the design of capacitive couplers, the core is usually installed in an insulating porcelain bushing filled with insulating oil. The two ends of the porcelain bushing are equipped with metal flanges for combination connection and fixation. When the voltage is 110kV and above, the coupling capacitor is composed of several capacitors connected in series.

[0003] When existing capacitive couplers are used between phases, the overall length of the capacitive coupler and the length of its leads are fixed. As a result, when connecting between phases, the spacing between the two leads may not be suitable for the spacing between phases, making it impossible for the capacitive coupler to be successfully connected between phases.

Both the upper and lower ends of the capacitive coupler body are coaxially combined with lead-out ends. Each lead-out end is coaxially fixed to a fixing sleeve. The top of each fixing sleeve is fixed to a U-shaped bracket. At the same time, a phase wire fixing component is provided between both sides of the U-shaped bracket to stably constrain and fix the phase wire through the phase wire fixing component.

[0007] Position adjustment components are combined on both sides of the U-shaped bracket, and the phase wire fixing components are fixed between the position adjustment components on the adjacent sides, so as to quickly adjust and lock the position of the phase wire fixing components through the position adjustment components.

[0008] Preferably, both the fixing sleeve and the U-shaped bracket are metal conductive components, and the inner end of the fixing sleeve is coaxially fixed with a conductive contact.

[0009] Preferably, the fixing sleeve and the lead-out end are coaxially combined by means of threaded connection, and when the conductive contact is pressed against the corresponding lead-out end, the vertical parts on both sides of the U-shaped bracket are vertically arranged along the longitudinal direction.

[0010] Preferably, all phase wire fixing components are metal conductive parts, each phase wire fixing component includes an arc-shaped clamp and a connecting screw. Each phase wire fixing component has two arc-shaped clamps, and the two arc-shaped clamps are aligned and joined together. Each arc-shaped clamp has a connecting hole in the horizontal direction at both the top and bottom positions, and the connecting screw is inserted between the corresponding connecting holes on both sides, so as to use the connecting screw to make the corresponding arc-shaped clamps on both sides be aligned and fixed together.

[0011] Preferably, the inner surface of the arc-shaped clamp is fixed with several conductive bumps with arc-shaped protrusions.

[0012] Preferably, the connecting screw and the connecting hole are coaxially combined by means of threaded engagement, and the outer end of the connecting screw is coaxially provided with an external hexagonal force groove.

[0013] Preferably, all the position adjustment components are metal conductive parts, and each position adjustment component includes a guide groove and a guide stud. The guide groove is vertically opened on both sides of the U-shaped bracket along the horizontal direction, and the guide groove is a through groove in the horizontal direction. The guide stud is fixed horizontally on the periphery of the arc-shaped clamp, and the guide stud passes through the corresponding guide groove on the same side in a sliding fit manner. At the same time, the part of the guide stud extending out of the guide groove is coaxially engaged with a clamping nut.

[0014] Preferably, the guide grooves are all vertically arranged waist-shaped grooves with open exteriors.

[0015] Preferably, the portion of the guide stud between the outer side of the U-shaped bracket and the clamping nut is coaxially slidably fitted with a metal washer, and the outer end of the guide stud is coaxially fixed with an end plate.

[0016] Preferably, the front outer end of the U-shaped bracket is provided with mounting holes along the longitudinal direction, and the mounting holes are perpendicularly connected to the corresponding guide grooves. At the same time, anti-detachment screws are inserted into the mounting holes along the longitudinal direction.

[0017] Using the aforementioned phase-to-phase capacitive coupler device, specifically in the use of the capacitive coupler body between phases, since the lead-out ends of the capacitive coupler body are all coaxially fixed with the fixing sleeves, and the phase wire fixing components are arranged between the two sides of the U-shaped bracket at the top of the fixing sleeves, the phase wires can be stably constrained and fixed by means of the two arc-shaped clamps of the phase wire fixing components being aligned and then fixed by the connecting screws inserted through the connecting holes. The method of constraining and fixing the phase wires is simple and easy to implement, and thus facilitates the use of the phase wire fixing components at both ends. The leads at both ends are connected to the phase lines, facilitating the quick connection of the capacitor coupler body between phases. Since the position adjustment components are assembled on both sides of the U-shaped bracket, and the phase line fixing component is fixed between the position adjustment components on both sides, the position of the phase line fixing component can be quickly adjusted and locked by the guide stud of the position adjustment component sliding vertically along the guide groove and tightening the clamping nut. The position adjustment method of the phase line fixing component is simple and easy to implement. Furthermore, based on the phase-to-phase... The actual spacing facilitates adaptive adjustment of the spacing between the phase wire fixing components at both ends, improving the flexibility of the phase wire fixing components. Simultaneously, it enables the capacitor coupler body to have a wide range of applications by utilizing the phase wire fixing components, further ensuring that the capacitor coupler body can be smoothly combined and connected between phases for use. Furthermore, since the front outer end of the U-shaped bracket has mounting holes perpendicularly communicating with the guide groove, and each mounting hole is longitudinally fitted with an anti-detachment screw, the anti-detachment screw can be tightened by inserting it into the guide groove to secure the capacitor coupler. The top of the guide groove is sealed, a simple and easy-to-implement method that prevents the guide stud from accidentally detaching the phase wire fixing assembly from the U-shaped bracket, thus improving the reliability of the phase wire fixing assembly. Simultaneously, the sealing of the top of the guide groove can be released by turning the anti-detachment screw to disengage it from the guide groove. This simple and easy-to-implement method facilitates subsequent removal of the phase wire fixing assembly from the U-shaped bracket by sliding the guide stud from the outer end of the guide groove, making subsequent maintenance and replacement of the phase wire fixing assembly easier.

[0018] The beneficial effects are as follows: 1. The present invention has a fixed sleeve coaxially fixed to the lead-out ends of the capacitor coupler body, and a phase wire fixing component is provided between the two sides of the U-shaped bracket at the top of the fixed sleeve. In this way, the phase wire can be stably constrained and fixed by the two arc-shaped clamps of the phase wire fixing component being aligned and then fixed by the connecting screws inserted through the connecting holes. The method of constraining and fixing the phase wire is simple and easy to implement. It is also convenient to use the phase wire fixing components at both ends to connect the lead-out ends at both ends to the phase wires respectively, so as to facilitate the quick connection of the capacitor coupler body between phases for use.

[0019] 2. Position adjustment components are assembled on both sides of the U-shaped bracket, and the phase wire fixing components are fixed between the position adjustment components on both sides. Then, by sliding the guide stud of the position adjustment component vertically along the guide groove and tightening the clamping nut, the position of the phase wire fixing component can be quickly adjusted and locked. The position adjustment method of the phase wire fixing component is simple and easy to implement. Furthermore, according to the actual distance between the phases, it is easy to adapt and adjust the distance between the phase wire fixing components at both ends, which improves the flexibility of the phase wire fixing components. At the same time, it realizes that the capacitor coupler body has a wide range of applications by means of the phase wire fixing components, and further ensures that the capacitor coupler body can be smoothly assembled and connected between phases for use.

[0020] 3. The front outer end of the U-shaped bracket is provided with mounting holes that are perpendicular to the guide groove. Anti-detachment screws are inserted into the mounting holes along the longitudinal direction. The top of the guide groove can be sealed by twisting the anti-detachment screws into the guide groove. The sealing method of the top of the guide groove is simple and easy to implement, thereby preventing the guide stud from accidentally separating the phase wire fixing component from the U-shaped bracket, thus improving the reliability of the phase wire fixing component.

[0021] 4. At the same time, the top of the guide groove can be unblocked by turning the anti-loosening screw to release it. The method of unblocking the top of the guide groove is simple and easy to implement.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-7As shown, this utility model provides a phase-to-phase capacitive coupler device, including a capacitive coupler body 4. The axis of the capacitive coupler body 4 is vertically arranged. Lead-out ends 401 are coaxially combined at both the upper and lower ends of the capacitive coupler body 4. Each lead-out end 401 is coaxially fixed to a fixing sleeve 3, and a U-shaped bracket 1 is fixed to the top of each fixing sleeve 3. A phase wire fixing assembly 2 is provided between both sides of the U-shaped bracket 1 to stably constrain and fix the phase wires. Specifically, each phase wire fixing assembly 2 is a metal conductive component, and each phase wire fixing assembly 2 includes an arc-shaped clamp 203 and a connecting screw 201. The number of arc-shaped clamps 203 in each phase wire fixing assembly 2 is two, and the two clamps are... The two arc-shaped clamps 203 are aligned and joined together. Connecting holes 205 are provided at both the top and bottom positions of the arc-shaped clamps 203 along the horizontal direction. Connecting screws 201 are inserted between the corresponding connecting holes 205 on both sides. These connecting screws 201 are used to secure the two arc-shaped clamps 203 together. This arrangement aims to stably constrain and fix the phase wire by aligning the two arc-shaped clamps 203 together and fixing them with connecting screws 201 inserted through the connecting holes 205. This method of constraining and fixing the phase wire is simple and easy to implement, and facilitates the connection of the lead-out ends 401 at both ends to the phase wire using the phase wire fixing components 2 at both ends.

[0034] See Figures 1-5 As shown, position adjustment components 5 are assembled on both sides of the U-shaped bracket 1, and the phase wire fixing components 2 are fixed between the position adjustment components 5 at adjacent positions on both sides. This allows for quick adjustment and locking of the position of the phase wire fixing components 2 via the position adjustment components 5. Specifically, the position adjustment components 5 are all metal conductive parts, each including a guide groove 503 and a guide stud 506. The guide grooves 503 are vertically formed on both sides of the U-shaped bracket 1 along the horizontal direction, and the guide grooves 503 are all through grooves in the horizontal direction. The guides are horizontally fixed on the periphery of the arc-shaped clamp 203. The studs 506 and the guide studs 506 all slide through the corresponding guide grooves 503 on the same side. At the same time, the parts of the guide studs 506 extending out of the guide grooves 503 are coaxially engaged with the clamping nuts 505. The purpose of this arrangement is that by sliding the guide studs 506 of the position adjustment component 5 vertically along the guide grooves 503 and tightening the clamping nuts 505, the position of the phase wire fixing component 2 can be quickly adjusted and locked. The position adjustment method of the phase wire fixing component 2 is simple and easy to implement. Then, according to the actual distance between the phases, it is convenient to make adaptive adjustments to the distance between the phase wire fixing components 2 at both ends.

[0035] See Figures 1-5 As shown, the following optimizations were made to the fixing sleeve 3, U-shaped bracket 1, phase wire fixing assembly 2, and position adjustment assembly 5. Specifically, for the fixing sleeve 3 and U-shaped bracket 1, both are metal conductive parts. The inner end of the fixing sleeve 3 is coaxially fixed with a conductive contact 301. This arrangement ensures that both the fixing sleeve 3 and U-shaped bracket 1 have conductivity, and the fixing sleeve 3 can achieve a stable electrical connection with the lead-out end 401 through the conductive contact 301. Optionally, the fixing sleeve 3 and the lead-out end 401 are coaxially combined by threaded engagement. When the conductive contact 301 is pressed against the corresponding lead-out end 401, the vertical portions on both sides of the U-shaped bracket 1 are vertically arranged longitudinally. This arrangement facilitates the quick assembly and disassembly of the fixing sleeve 3 with the lead-out end 401 by twisting, and also provides a clear indication when the fixing sleeve 3 and the lead-out end 401 are in place. Specifically, in the phase wire fixing assembly 2, the inner surface of the arc-shaped clamp 203 is fixed with several conductive bumps with arc-shaped protrusions, so as to enable the phase wire to achieve a more stable electrical connection with the arc-shaped clamp 203. Furthermore, the connecting screw 201 and the connecting hole 205 are coaxially combined by threaded engagement, and the outer end of the connecting screw 201 is coaxially provided with an external hexagonal force groove 202, so as to achieve quick assembly and disassembly of the connecting screw 201 and the connecting hole 205 by tightening, and also to facilitate tightening the connecting screw 201 with tools such as an external hexagonal wrench.

[0036] See Figures 1-7As shown, specifically in the position adjustment component 5, the guide grooves 503 are all vertically arranged waist-shaped grooves with open exteriors, so that the guide grooves 503 have sufficient length range in the vertical direction for the phase wire fixing component 2 to adjust the position, and also facilitate the guide studs 506 to slide in and out from the outer end of the guide grooves 503. Further optionally, the portion of the guide studs 506 between the outer side of the U-shaped bracket 1 and the clamping nut 505 is coaxially slidably fitted with metal washers 507, and the outer end of the guide studs 506 is coaxially fixed with end plates 504. This arrangement firstly facilitates the use of metal washers 507 to improve locking stability and conductivity, and also facilitates the use of end plates 504 to prevent the clamping nut 505 from accidentally separating from the guide studs 506. Furthermore, each of the outer front ends of the U-shaped bracket 1 is provided with a mounting hole 502 along the longitudinal direction, and each mounting hole 502 is perpendicularly connected to the corresponding guide groove 503. At the same time, each mounting hole 502 is fitted with an anti-detachment screw 501 along the longitudinal direction. The advantage of this arrangement is that by turning the anti-detachment screw 501 into the guide groove 503, the top of the guide groove 503 can be sealed. The sealing method of the top of the guide groove 503 is simple and easy to implement, thereby preventing the guide stud 506 from accidentally detaching the phase wire fixing assembly 2 from the U-shaped bracket 1. At the same time, by turning the anti-detachment screw 501 out of the guide groove 503, the sealing state of the top of the guide groove 503 can be released. The unsealing method of the top of the guide groove 503 is simple and easy to implement, which facilitates the subsequent removal of the phase wire fixing assembly 2 from the U-shaped bracket 1 by the guide stud 506 sliding out from the outer end of the guide groove 503.

[0037] With the above structure, specifically in the use of the capacitor coupler body 4 between phases, since the fixing sleeves 3 are coaxially fixed to the lead-out ends 401 of the capacitor coupler body 4, and the phase wire fixing components 2 are provided between the two sides of the U-shaped bracket 1 at the top of the fixing sleeves 3, the phase wires can be stably constrained and fixed by the two arc-shaped clamps 203 of the phase wire fixing components 2 closing together and being fixed by the connecting screws 201 inserted through the connecting holes 205. The method of constraining and fixing the phase wires is simple and easy to implement, and thus it is convenient to use the phase wire fixing components 2 at both ends to connect the lead-out ends. The ends 401 are connected to the phase lines respectively, which facilitates the quick connection of the capacitor coupler body 4 between the phases for use. Since the position adjustment components 5 are combined on both sides of the U-shaped bracket 1, and the phase line fixing components 2 are fixed between the position adjustment components 5 on both sides, the position of the phase line fixing components 2 can be quickly adjusted and locked by the guide studs 506 of the position adjustment components 5 sliding vertically along the guide grooves 503 and tightening the clamping nuts 505. The position adjustment method of the phase line fixing components 2 is simple and easy to implement. Furthermore, based on the actual distance between the phases, it is convenient to adjust the positions of both ends. The spacing between the phase wire fixing components 2 is adjusted for adaptability, improving the flexibility of use of the phase wire fixing components 2. Simultaneously, the phase wire fixing components 2 enable the capacitor coupler body 4 to have a wide range of applications, further ensuring that the capacitor coupler body 4 can be smoothly combined and connected between phases for use. Furthermore, since the front outer end of each U-shaped bracket 1 has mounting holes 502 perpendicularly communicating with the guide groove 503, and each mounting hole 502 is longitudinally fitted with an anti-detachment screw 501, the top of the guide groove 503 can be secured by twisting the anti-detachment screw 501 through the guide groove 503. The sealing method for the top of the guide groove 503 is simple and easy to implement, thereby preventing the guide stud 506 from accidentally detaching the phase wire fixing assembly 2 from the U-shaped bracket 1, improving the reliability of the phase wire fixing assembly 2. At the same time, the top sealing of the guide groove 503 can be released by turning the anti-detachment screw 501 to release the guide groove 503. The method of releasing the top sealing of the guide groove 503 is simple and easy to implement, which facilitates the subsequent removal of the phase wire fixing assembly 2 from the U-shaped bracket 1 by sliding the guide stud 506 from the outer end of the guide groove 503, making it convenient for subsequent maintenance and replacement of the phase wire fixing assembly 2.
