Description

Technical Field

[0001] This utility model relates to the field of overhead contact line parameter testing technology, and in particular to an overhead contact line parameter testing device. Background Technology

[0002] The overhead contact line parameter tester is mainly used to accurately measure the power frequency parameters of the overhead contact line of electrified railways, such as impedance, admittance, and mutual inductance. It is an important tool to ensure the safe, stable, and efficient operation of the railway power supply system. Structurally, this equipment typically adopts an integrated, robust chassis, integrating a built-in frequency converter, a high-precision data acquisition module, a central processing unit, and a human-machine interface. It applies specific test signals to the overhead contact line by connecting multiple dedicated test cables and collects the responses. Finally, through internal calculations, it obtains the line parameters, providing direct data for the design, verification, and condition assessment of the power supply system.

[0003] Current overhead contact line parameter testing equipment requires operators to climb onto the contact line, attach the conductive clamp, and then connect the clamp to the testing unit's interface via a conductive wire. This method has several drawbacks: operators must climb to connect to the contact line for each test, resulting in extremely low efficiency; furthermore, the conductive clamp and conductive wire require separate storage bags, making them inconvenient to carry and use. Therefore, further improvements are needed. To address this, we have proposed an overhead contact line parameter testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a contact network line parameter testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a contact network line parameter testing device, comprising a testing instrument host and multiple conductive wires, one end of each conductive wire being connected to the testing interface of the testing instrument host, and further comprising several insulating rods and multiple clamping assemblies connected to the conductive wires, wherein the clamping assemblies are detachably fixedly connected to the insulating rods, the clamping assemblies comprising a flat plate, the surface of the flat plate being provided with a groove, and a conductive plate being embedded in the groove, the conductive wire being fixedly connected to the conductive plate, a support being fixedly provided on the surface of the flat plate, and a bracket being hinged to the support, an arc-shaped clamping plate and an end plate being respectively provided at both ends of the bracket, a spring being fixedly connected between the end plate and the flat plate, and a first curved plate being provided at the other end of the arc-shaped clamping plate;

[0006] The main unit of the tester has a storage slot on one side, and a storage box is slidably connected inside the storage slot. The side wall of the storage box has a through hole, and a plug-in component is installed inside the through hole.

[0007] Furthermore, each of the insulating rods is fixedly connected to a screw at one end and the bottom end of the plate, and the other end of the insulating rod is provided with a threaded groove for screwing in the screw.

[0008] Furthermore, the arc-shaped clamp, bracket, end plate, and first curved plate are an integral structure, with the arc-shaped clamp facing the conductive plate.

[0009] Furthermore, a second curved plate is provided on the top of the flat plate, and a Y-shaped opening is formed between the first curved plate and the second curved plate.

[0010] Furthermore, the plug-in assembly includes a locking rod located inside the through hole and slidably connected to the through hole. A baffle is fixedly connected to one end of the locking rod inside the storage box. A tension spring is fixedly connected to the baffle and the inner side wall of the storage box. The other end of the locking rod outside the storage box is inserted into the locking hole.

[0011] Furthermore, the storage box is fixedly connected to a handle on one side outside the main unit of the testing instrument.

[0012] The beneficial effects of this utility model are:

[0013] 1. When using this utility model, the tester host, clamping assembly, conductive wire and several insulating rods are set. The several insulating rods can be spliced ​​into a suitable length by screws. Then the clamping assembly is installed and connected to the spliced ​​insulating rods.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figs. 1-3 As shown, a contact network line parameter testing device is disclosed, including a tester host 1 and multiple conductive wires 3. One end of the conductive wires 3 is connected to the test interface of the tester host 1. The device also includes several insulating rods 4 and multiple clamping components 2 connected to the conductive wires 3. The clamping components 2 and the insulating rods 4 are detachably fixedly connected. The clamping components 2 include a flat plate 21 with a groove on its surface and a conductive plate 22 embedded in the groove. The conductive wires 3 are fixedly connected to the conductive plate 22. A support 23 is fixedly fixed on the surface of the flat plate 21, and a bracket 24 is hinged to the support 23. An arc-shaped clamping plate 25 and an end plate 26 are respectively provided at both ends of the bracket 24. A spring 27 is fixedly connected between the end plate 26 and the flat plate 21. A first bent plate 28 is provided at the other end of the arc-shaped clamping plate 25.

[0023] The main unit 1 of the tester has a storage slot 7 on one side, and a storage box 8 is slidably connected inside the storage slot 7. The side wall of the storage box 8 has a through hole 81, and a plug-in component 9 is installed inside the through hole 81.

[0024] In this embodiment, the tester host 1 and the conductive wire 3 adopt existing technology. The specific model of the tester host 1 can be SR9001. Its specific testing working principle and operation method will not be described here.

[0025] Each insulating rod 4 has a screw 5 fixedly connected to one end and the bottom end of the plate 21, and the other end of the insulating rod 4 has a threaded groove for screwing in the screw 5.

[0026] When using this device, multiple insulating rods 4 can be taken out and spliced ​​according to the height of the contact wire. The splicing method is to screw the screw 5 at the end of one insulating rod 4 into the threaded groove at the end of another insulating rod 4. After the multiple insulating rods 4 are spliced ​​to the appropriate length, the screw 5 on the plate 21 is screwed into the threaded groove of the last insulating rod 4. At this time, you can stand on the ground holding the insulating rod 4 and connect the clamping assembly 2 to the contact wire. After use, the insulating rods 4 and the clamping assembly 2 can be disassembled and stored in the storage box 8.

[0027] The arc-shaped clamp 25, the bracket 24, the end plate 26 and the first curved plate 28 are an integral structure, with the arc-shaped clamp 25 facing the conductive plate 22.

[0028] When the clamping assembly 2 is inserted into the contact wire using the insulating rod 4, the first curved plate 28 and the flat plate 21 are in contact with the contact wire. Then, by forcefully pushing the clamping assembly 2 with the insulating rod 4, the first curved plate 28 and the flat plate 21 are separated by the contact wire under pressure. At this time, the spring 27 is compressed. When the contact wire is secured between the arc-shaped clamping plate 25 and the flat plate 21, the spring 27 pushes the end plate 26 to reset. At this point, the arc-shaped clamping plate 25 and the flat plate 21 clamp the contact wire, and the first curved plate 28 re-enters contact with the flat plate 21. Using this method to connect the contact wire eliminates the need for climbing; connection can be performed from the ground.

[0029] A second curved plate 29 is provided on the top of the flat plate 21, and a Y-shaped opening is formed between the first curved plate 28 and the second curved plate 29. By providing the second curved plate 29, the included angle between the opening of the flat plate 21 and the arc-shaped clamping plate 25 can be increased, making it easier for the clamping assembly 2 to be aligned with the contact wire and snapped in place.

[0030] The plug-in assembly 9 includes a locking rod 91 located inside the through hole 81 and slidably connected to the through hole 81. One end of the locking rod 91 located inside the storage box 8 is fixedly connected to a baffle 92. The baffle 92 and the inner side wall of the storage box 8 are fixedly connected to a tension spring 93. The other end of the locking rod 91 located outside the storage box 8 is inserted into the locking hole 6.

[0031] The storage box 8 is fixedly connected to a handle on one side outside the main unit 1 of the tester.

[0032] After the clamping assembly 2, insulating rod 4, and conductive wire 3 are stored inside the storage box 8, press the locking rod 91 to retract it into the storage box 8. At this time, the tension spring 93 is stretched. Then, push the storage box 8 into the storage slot 7 using the handle. When the locking rod 91 is aligned with the locking hole 6, the tension spring 93 pulls the baffle 92 and the locking rod 91 to reset, so that the locking rod 91 is locked into the locking hole 6, thus fixing the storage box 8.

[0033] When using it again, squeeze the lever 91 to separate it from the hole 6, and then pull the storage box 8 out of the storage slot 7 using the handle.

[0034] Working principle: During operation, first take out the conductive wire 3, insulating rod 4 and clamping assembly 2 from the storage box 8. According to the height of the contact network, splice multiple insulating rods 4 with the threaded groove through the screw 5, and screw the bottom screw 5 of the plate 21 of the clamping assembly 2 into the threaded groove of the last insulating rod 4.

[0035] After assembly, insert the conductive wire 3 into the test interface of the tester host 1. Hold the assembled insulating rod 4 and push the clamping assembly 2 towards the contact network, allowing the contact network to enter through the Y-shaped opening formed by the first curved plate 28 and the second curved plate 29. Squeeze the first curved plate 28 to make the bracket 24 rotate around the support 23 and compress the spring 27 until the contact network is locked between the arc-shaped clamping plate 25 and the conductive plate 22. At this time, the spring 27 pushes the end plate 26 to make the arc-shaped clamping plate 25 clamp the contact network, and the conductive wire 3 forms an electrical connection with the contact network through the conductive plate 22. Then, perform circuit parameter testing through the tester host 1. After the test is completed, pull the clamping assembly 2 downward with the insulating rod 4 to separate the clamping assembly 2 from the contact network.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
