Description

Technical Field

[0001] The present invention belongs to the technical field of pole-mounted switch testing, and specifically relates to a universal aviation plug adapter for distribution network pole-mounted switch testing. Background Art

[0002] Under the existing technology, the operating pole-mounted vacuum circuit breaker is installed on an electric pole at a height of 6-8 meters from the ground, and the operating FTU controller is installed on an electric pole at a height of 2-4 meters from the ground. The vacuum circuit breaker and the FTU controller are connected by a whole aviation plug wire. There is no break or access point in the middle of the aviation plug wire, which is not convenient for test wiring access. The overall space of the FTU controller is compact, and generally there are no wiring terminals provided for test wiring. During the relay protection test, it is necessary to connect the current, voltage, and input / output lines to the inside of the FTU controller. The test wiring requires personnel to climb the pole for operation, and if it is necessary to adjust the input / output wiring during the test, personnel need to climb the pole to the FTU controller again to adjust the wiring, which takes a long time. There are a total of 7 current and voltage lines connected to the FTU controller, all of which are single copper wires, and small wire clips or small plugs are used for connection at the connection points. Short circuits or poor contacts are likely to occur in the existing space of the FTU controller. The normal power supply of the existing FTU controller is powered by PT. During the test, if voltage is applied, it may cause reverse power transmission. If voltage is not applied, the FTU controller is powered by a battery, which cannot ensure the test accuracy.

[0003] In summary, the present invention provides a universal aviation plug adapter for distribution network pole-mounted switch testing to solve the above problems. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a universal aviation plug adapter for distribution network pole-mounted switch testing, which is achieved by the following specific technical means:

[0007] The female socket mounting base includes a cylindrical housing, which is composed of two sections with different inner diameters. The inner diameter of the section closer to its opening is larger, and the inner diameter of the section farther from its opening is smaller. The inner diameters of the inner walls of the two sections are respectively equal to the outer diameters of the two sections of the replaceable aviation socket female. A connecting plate for fixedly connecting with the debugging junction box is arranged on the outer side of the opening end of the cylindrical housing. A female socket connecting piece is arranged on the inner wall of the cylindrical housing at the end far from the connecting plate. A rotating piece for cooperating with the locking component to fix the replaceable aviation socket female is installed inside the opening of the cylindrical housing. A sealing component is installed in the section with a smaller inner diameter of the cylindrical housing.

[0008] As a preferred technical solution of the present invention, the female socket connecting piece includes a fixed seat fixedly arranged on the inner wall of the cylindrical housing. An installation groove is formed on the side of the fixed seat facing the opening of the cylindrical housing. A connecting contact is slidably installed in the installation groove, and one end of the connecting contact penetrates out of the installation groove. A first spring is also installed in the installation groove. One end of the first spring is fixedly connected to the connecting contact, and the other end is connected with a pin. The end of the pin far from the first spring penetrates out of the end of the cylindrical housing far from its opening.

[0009] As a preferred technical solution of the present invention, the locking component includes a locking pin, which is fixedly connected with the replaceable aviation socket female and is radially arranged on the outer side of the replaceable aviation socket female.

[0010] As a preferred technical solution of the present invention, the rotating piece includes a rotating ring rotatably connected with the cylindrical housing. One end of the rotating ring penetrates out of the opening of the cylindrical housing, and a knob is arranged on the outer side of the penetrated end. A guide groove is arranged on the inner wall of the rotating ring, and a triangular stop block is arranged on one side of the guide groove.

[0011] As a preferred technical solution of the present invention, an annular groove is arranged on the inner wall of the replaceable aviation socket female around the rotating ring. A torsion spring is installed inside the annular groove, and both ends of the torsion spring are fixedly connected with the rotating ring and the annular groove respectively. A limiting block is arranged on the outer side of the rotating ring in the annular groove, and a limiting baffle is arranged on one side inner wall of the annular groove. Both the limiting block and the limiting baffle are provided with a plurality of them and are located in the same plane, and the limiting block and the limiting baffle are arranged alternately.

[0012] As a preferred technical solution of the present invention, the sealing assembly includes a straight groove opened on an inner wall of a section with a smaller inner diameter of the cylindrical shell. A first sliding groove and a second sliding groove are sequentially opened on the side wall of the straight groove at positions from near to far away from the central axis of the cylindrical shell. A sealing plate is further installed inside the straight groove. One end of the sealing plate is in an equilateral triangle style, and the other end is in a rectangular style. The width of the rectangle is equal to the width of the straight groove. First guide pins are arranged on both sides of the sealing plate in the rectangular style, and the first guide pins penetrate into the first sliding groove.

[0015] As a preferred technical solution of the present invention, anti-fooling grooves are arranged on the inner wall of the rotating ring and the inner wall of the section with a larger inner diameter of the cylindrical shell. An anti-fooling block is arranged on the surface of the larger-diameter section of the replaceable female aviation plug near the position of its smaller-diameter section.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The FTU controller and the pole-mounted switch can be respectively connected to the switch pin interface and the controller pin interface through the aviation plug wire and the aviation plug connection assembly. When adjusting the input and output quantities, the operation can be carried out on the terminal block of the debugging junction box on the ground, avoiding frequent pole climbing and saving test time. Only two pole climbs for connecting and removing the adapter wiring are required for a pole-mounted switch test. Compared with the traditional test, 4 pole climbs are reduced (calculated according to the normal working efficiency, each pole climb takes about 5 minutes from preparation to getting off the pole), and the wiring time for adjusting the input and output quantities is 20 minutes. Moreover, the wiring only requires plugging and unplugging the aviation plug and wiring operation at the wiring terminal. Compared with the traditional test of opening the FTU controller through a wire clamp and looking up the voltage and current wiring ports in the instruction manual, 10 minutes of time can be saved.

[0018] 2. The terminal block is equipped with a connecting piece for controlling opening and closing. By connecting the contacts on both sides of the connecting piece terminal block, an external power supply can be connected to the terminal block on the FTU controller side, avoiding reverse power transmission to the combined transformer of the pole-mounted switch. At the same time, it can ensure that the FTU does not experience power loss of the controller due to a long test time.

[0019] 3. By setting a detachable and replaceable female aviation plug, after the female aviation plug is damaged due to frequent plugging and unplugging, only the replaceable female aviation plug needs to be replaced separately, without the need to replace the entire aviation plug connection component, eliminating the process of re-wiring the aviation plug connection component with the switch pin interface and the controller pin interface, and improving the maintenance convenience of the device.

[0034] The following further describes the embodiments of the present invention in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0035] The present invention provides an aviation plug universal adapter for testing a switch on a distribution network pole, including a debugging junction box 1. A terminal block 2 is arranged on the top of the debugging junction box 1. A switch pin interface 3 and a controller pin interface 4 are respectively arranged on both sides of the terminal block 2 on the top of the debugging junction box 1. A power supply interface 5 is further arranged on one side of the debugging junction box 1. A plurality of aviation plug connection components 6 are arranged on both sides of the debugging junction box 1. The aviation plug connection component 6 includes a replaceable aviation plug female socket 7 and a female socket mounting seat 9;

[0036] The replaceable aviation plug female socket 7 is composed of two concentric sections with different outer diameters. A connecting female socket 71 is arranged at the end with a larger outer diameter, and a connecting contact 72 is arranged at the end with a smaller outer diameter. A limiting ring 73 is further arranged on the outer side of the section with a larger outer diameter of the replaceable aviation plug female socket 7. A locking component 8 is arranged at a position of the replaceable aviation plug female socket 7 close to the limiting ring 73;

[0037] The female connector mounting base 9 includes a cylindrical housing 91. The cylindrical housing 91 consists of two sections with different inner diameters. The inner diameter of the section closer to its opening is larger, and the inner diameter of the section farther from its opening is smaller. The inner diameters of the inner walls of the two sections are respectively equal to the outer diameters of the two sections of the replaceable female aviation plug 7. A connecting plate 92 fixedly connected to the debugging junction box 1 is arranged on the outer side of the opening end of the cylindrical housing 91. A female connector 10 is arranged on the inner wall of the end of the cylindrical housing 91 far from the connecting plate 92. A rotating member 11 that cooperates with the locking assembly 8 to fix the replaceable female aviation plug 7 is installed inside the opening of the cylindrical housing 91. A sealing assembly 16 is installed inside the section of the cylindrical housing 91 with a smaller inner diameter.

[0038] As Figure 1 shown, the aviation plug connection components 6 on both sides of the debugging junction box 1 are respectively electrically connected to the switch pin interface 3 and the controller pin interface 4. The pins 105 of the FTU controller and the pole-mounted switch can be connected to the debugging junction box 1 through the aviation plug connection components 6 via an aviation plug wire. Then, use a wire to connect the switch pin interface 3 and the controller pin interface 4 through the terminal block 2. When adjusting the input and output quantities, operations can be performed at the ground wiring terminal block 2, avoiding frequent pole climbing and saving test time. During the test, power can be supplied through the power interface 5. The power interface 5 is also electrically connected to the switch pin interface 3 and the controller pin interface 4. Use a wire to connect the power supply to the FTU controller and the pole-mounted switch to meet the power supply requirements for the pole-mounted switch and the FTU controller during the test process. The wire is connected to the switch pin interface 3 and the controller pin interface 4 in a plug-in manner, with good and stable contact, reducing the probability of short circuit and open circuit problems, and at the same time facilitating the adjustment of the circuit during the test process.

[0039] It should be noted that both the switch pin interface 3 and the controller pin interface 4 are provided with multiple ones. Some of the switch pin interfaces 3 and the controller pin interfaces 4 are used to realize the access of current and voltage, and some of the switch pin interfaces 3 and the controller pin interfaces 4 are used for the transmission of control signals during the experiment. Multiple aviation plug connection components 6 of different models are provided on both sides of the debugging junction box 1, which are respectively used to connect common aviation plug model wires such as 26-core, 20-core, 14-core, 6-core, 4-core, etc., in order to adapt to pole-mounted switches and FTU controllers with different interface specifications. A connecting piece is arranged between the contacts on both sides of the terminal block 2 for controlling the open and closed circuit between the contacts on both sides of the terminal block 2. During the experiment, by connecting the contacts on both sides of the terminal block 2 through the connecting piece, an external power supply can be connected to the terminal block 2 on the FTU controller side, avoiding reverse power transmission to the combined transformer of the pole-mounted switch, and at the same time ensuring that the FTU does not experience controller power loss due to a long test time.

[0040] The female connector 10 includes a fixing base 101 fixedly arranged on the inner wall of the cylindrical shell 91. An installation groove 102 is formed on the side of the fixing base 101 facing the opening of the cylindrical shell 91. A connection contact 103 is slidably installed in the installation groove 102, and one end of the connection contact 103 passes out of the installation groove 102. A first spring 104 is also installed in the installation groove 102. One end of the first spring 104 is fixedly connected to the connection contact 103, and the other end is connected to a pin 105. The end of the pin 105 away from the first spring 104 passes out of the end of the cylindrical shell 91 away from its opening.

[0041] The locking assembly 8 includes a locking pin 81. The locking pin 81 is fixedly connected to the replaceable female aviation plug 7 and is radially arranged outside the replaceable female aviation plug 7.

[0042] The rotating member 11 includes a rotating ring 111 rotatably connected to the cylindrical shell 91. One end of the rotating ring 111 passes out of the opening of the cylindrical shell 91, and a knob 112 is arranged on the outside of the passing-out end. A guide groove 113 is arranged on the inner wall of the rotating ring 111, and a triangular stop block 114 is arranged on one side of the guide groove 113.

[0043] An annular groove 12 is arranged on the inner wall of the replaceable female aviation plug 7 around the rotating ring 111. A torsion spring 13 is installed inside the annular groove 12, and both ends of the torsion spring 13 are fixedly connected to the rotating ring 111 and the annular groove 12 respectively. A limiting block 14 is arranged on the outside of the rotating ring 111 in the annular groove 12, and a limiting baffle 15 is arranged on one side inner wall of the annular groove 12. A plurality of limiting blocks 14 and limiting baffles 15 are arranged and located in the same plane, and the limiting blocks 14 and the limiting baffles 15 are arranged alternately.

[0044] It should be noted that within the same aviation plug connection assembly 6, the number of connection contacts 72, connection contacts 103, first springs 104 and pins 105 is the same as the number of cores of the female connection 71.

[0045] Such as Figures 2 - 12As shown, the replaceable aircraft plug-in port 7 and the cylindrical shell 91 are detachably connected and fixed to the rotating member 11 by a locking pin 81. In the process of inserting the replaceable aircraft plug-in port 7 into the cylindrical shell 91, the locking pin 81 will enter the guide groove 113 as the replaceable aircraft plug-in port 7 is inserted. After the locking pin 81 enters the guide groove 113, as the replaceable aircraft plug-in port 7 is inserted, it will contact the inclined surface of the triangular stopper 114 and push the triangular stopper 114 to rotate until the locking pin 81 passes over the triangular stopper 114. Under the action of the torsion spring 13, the rotating ring 111 is reset, and the lock is locked by the triangular stopper 114. The fixing pin 81 is restricted in the guide groove 113 to fix the replaceable aircraft plug port 7. During the insertion process, the connecting contact 72 contacts the connecting contact 103 and pushes the connecting contact 103 to squeeze the first spring 104. The first spring 104 ensures the stability of the connection between the connecting contact 72 and the connecting contact 103. The connection between the connecting contact 72 and the pin 105 is achieved through the connecting contact 103 and the first spring 104. During the removal of the replaceable aircraft plug port 7, it is only necessary to rotate the rotating ring 111 through the knob 112 to offset the triangular stopper 114 from the locking pin 81, and the replaceable aircraft plug port 7 can be pulled out.

[0046] By setting up a detachable and replaceable aircraft plug mother port 7, when the aircraft plug mother port is damaged due to frequent plugging and unplugging, it is only necessary to replace the replaceable aircraft plug mother port 7 alone, without replacing the entire aviation plug connection component 6, thereby eliminating the process of rewiring the aviation plug connection component 6 with the switch pin interface 3 and the controller pin interface 4, thereby improving the maintenance convenience of the device.

[0047] Anti-mock grooves 17 are provided on the inner wall of the rotating ring 111 and the inner wall of the larger diameter section of the cylindrical shell 91, and an anti-mock block 18 is provided on the surface of the larger diameter section of the replaceable aircraft carrier port 7 near the smaller diameter section.

[0048] like Figures 2 - 12 As shown, by designing the anti-mistake groove 17 and the anti-mistake block 18, during the installation of the replaceable aircraft plug socket 7, it is ensured that the replaceable aircraft plug socket 7 is inserted into the cylindrical shell 91 at a correct angle.

[0049] It should be noted that the size of the fool-proof block 18 is adapted to the size of the fool-proof groove 17 and is larger than the size of the guide groove 113 to prevent the fool-proof block 18 from being mistakenly inserted into the guide groove 113 .

[0050] The sealing assembly 16 includes a straight groove 161 formed on the inner wall of a section with a smaller inner diameter of the cylindrical housing 91. On the side wall of the straight groove 161, a first sliding groove 162 and a second sliding groove 163 are successively formed at positions from near to far away from the central axis of the cylindrical housing 91. A sealing plate 164 is also installed inside the straight groove 161. One end of the sealing plate 164 is in an equilateral triangle style, and the other end is in a rectangular style, and the width of the rectangle is equal to the width of the straight groove 161. First guide pins 165 are provided on both sides of the sealing plate 164 in the rectangular style, and the first guide pins 165 penetrate into the first sliding groove 162. An L-shaped block 166 is also provided at one end of the sealing plate 164 in the rectangular style. Second guide pins 167 are provided on both sides of the end of the L-shaped block 166 away from the sealing plate 164, and the second guide pins 167 penetrate into the second sliding groove 163.

[0051] The second sliding groove 163 is strip-shaped. The first sliding groove 162 consists of two sections. The section away from the opening of the cylindrical housing 91 is arranged in parallel with the second sliding groove 163, and the section close to the opening of the cylindrical housing 91 is inclined towards the central axis of the cylindrical housing 91.

[0052] The sealing assembly 16 further includes a connecting strip 168 rotatably connected to the second guide pin 167. One end of the connecting strip 168 away from the second guide pin 167 penetrates into a section with a larger inner diameter of the cylindrical housing 91, and a moving ring 169 is connected to the penetrated end. A second spring 1610 is installed between the section with a smaller diameter and the moving ring 169 inside the section with a larger inner diameter of the cylindrical housing 91.

[0053] Such as Figures 2 - 12As shown, during the process of inserting the replaceable aircraft plug mother port 7, the replaceable aircraft plug mother port 7 pushes the moving ring 169 to move toward the inside of the cylindrical shell 91, and the moving ring 169 drives the connecting strip 168 to move, and the connecting strip 168 drives the second guide pin 167 to move, and the second guide pin 167 pulls the L-shaped block 166 on the sealing plate 164 to move along the direction of the second guide groove 113. During the movement of the L-shaped block 166, the sealing plate 164 is pulled, so that the first guide pins 165 on both sides of the sealing plate 164 move from the oblique groove part of the first guide groove 113 to the part of the straight groove 161. During this process, the sealing plate 164 is flipped and collected in the straight groove 161 at the same time. After that, the sealing plate 164 and the moving ring 169 move synchronously toward the inside of the cylindrical shell 91. When the replaceable aircraft plug mother port 7 is removed, the second spring 16 10 pushes the moving ring 169 so that the moving ring 169 drives the second guide pin 167 to move toward the opening of the cylindrical shell 91 through the connecting strip 168, and the second guide pin 167 drives the sealing plate 164 and the first guide pin 165 to move synchronously until the first guide pin 165 moves to the connection between the straight groove 161 and the inclined groove of the first guide groove 113. After that, the moving ring 169 drives the second guide pin 167 to continue to move through the connecting strip 168 until the second guide pin 167 is pushed to the end of the inclined groove of the first guide groove 113. During this process, the sealing plate 164 flips to divide the space in the cylindrical shell 91 into two parts, ensuring the sealing of the space where the connecting contact 103 is located, and preventing dust from adhering to the connecting contact 103 during the replacement of the replaceable aircraft socket 7, affecting the conduction between the connecting contact 103 and the connecting contact 72.

[0054] It should be noted that there are multiple sealing plates 164 , and the multiple sealing plates 164 together separate the space inside the cylindrical shell 91 .

[0055] Specific working principle:

[0056] like Figures 1 - 12 As shown, the pole switch and FTU controller are connected to the aviation plug connection components 6 on both sides of the debugging junction box 1 through aviation plug wires, and the corresponding switch pin interface 3 and controller pin interface 4 and terminal block 2 are connected through wires to perform relay protection test;

[0057] When the replaceable aircraft plug mother port 7 in the aircraft plug connection assembly 6 is damaged due to long-term plugging and unplugging, the knob 112 is rotated to disengage the triangular stopper 114 in the guide groove 113 from the locking pin 81, and then the damaged replaceable aircraft plug mother port 7 is pulled out and a new replaceable aircraft plug mother port 7 is reinserted.

[0058] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
