Description

Technical Field

[0001] The present invention relates to the technical field of circuit detection auxiliary tools, and in particular to a wire guiding device for circuit detection and a use method thereof. Background Art

[0002] The secondary detection device of substation plays a vital role in the operation and maintenance of power system. It is the key to ensure the stable operation of secondary equipment in substations. It can monitor core electrical parameters such as current, voltage, power factor and frequency in real time, thereby providing accurate and comprehensive data support. Through real-time data analysis, the secondary detection device of substation can quickly detect potential faults and issue alarms in time, providing a strong basis for troubleshooting and repair. In addition, the device can also continuously evaluate the performance of equipment, help improve equipment reliability and reduce the risk of failure. Therefore, the secondary detection device of substation not only provides a solid technical guarantee for the stable operation of the power system, but also contributes an important force to the sustained and healthy development of the power industry. Its application undoubtedly adds an important weight to the safe and efficient operation of the power system.

[0003] The existing substation secondary detection device is equipped with a detection contact. By making the wire to be tested approach and contact the detection contact from beginning to end, the detection contact can accurately sense the change of the magnetic field, thereby accurately judging the state of the wire to be tested.

[0004] However, in actual applications, the position of the wire to be tested may deviate due to various reasons, which may cause the detection contact to be unable to accurately capture the existence of the wire to be tested, thereby causing deviations in the test results and affecting the accuracy of the test. Summary of the invention

[0005] Aiming at the problem that the position of the tested wire may deviate, thereby causing inaccurate detection results, the present invention provides a wire guiding device for circuit detection and a method of using the device, which can guide the tested wire to ensure that the tested wire does not deviate and the detection result is accurate.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is a wire guiding device for circuit detection, including a protective shell, which can protect the secondary detection device, and a guide is provided at the bottom of the protective shell, which can guide and limit the wire to be tested, and shield and isolate other wires; a clamping mechanism is provided on one side of the protective shell, and the clamping mechanism can clamp and fix the wire to be tested, send the wire to be tested to the entrance of the guide, and send the wire to be tested to the detection contact of the secondary detection device. The clamping mechanism can clamp the wire to be tested and accurately transfer it to the entrance of the guide, thereby ensuring that the wire to be tested can smoothly enter the guide. The guide can not only effectively guide and limit the path of the wire to be tested, so that it always remains within the effective detection range of the detection contact, but also effectively shield and isolate the interference of other wires, thereby significantly improving the accuracy and reliability of the detection.

[0007] Preferably, the guide member includes two mutually parallel guide shielding plates, and the guide shielding plates are fixed to the bottom of the protective shell. The wire to be tested is precisely confined between the two mutually parallel guide shielding plates, thereby ensuring that it is always kept within the effective detection range of the detection contact during the entire detection process, greatly improving the accuracy and stability of the detection.

[0008] Preferably, the clamping mechanism includes a connecting sleeve, one side of which is fixedly connected to the protective shell, a gear is installed inside the connecting sleeve, both sides of the gear are provided with racks meshing with the gear, and a clamping rod is fixed at the bottom of the rack. By rotating the gear, the two racks can be effectively regulated to move toward each other, thereby causing the two clamping rods to gather toward the center, thereby achieving a stable clamping of the wire.

[0009] Preferably, an adjustment knob is provided above the connecting sleeve, and the lower end of the adjustment knob is fixedly connected to the gear. The gear can be easily and quickly driven to rotate by turning the adjustment knob, and the operation is simple and quick.

[0010] Preferably, a clamping cylinder is provided below the rack, the upper end of the clamping cylinder is fixedly connected to the bottom of the rack, the upper end of the clamping rod is located in the clamping cylinder, and the clamping rod can slide up and down along the clamping cylinder and lock. The clamping rod can move up and down smoothly along the clamping cylinder and lock reliably, so as to conveniently clamp the wire to be tested and accurately adjust its height, thereby ensuring the flexibility and accuracy of the detection process.

[0011] Preferably, it also includes a support crossbar, which is placed horizontally and passes through the lower end of the clamping rod. The support crossbar has a stable supporting function and can effectively support the wire to be tested to ensure that it will not accidentally slip from the clamping rod during the detection process, thereby ensuring the safety and continuity of the detection.

[0012] Preferably, it also includes an arc-shaped rod, both ends of the arc-shaped rod are fixedly connected to the protective shell, both ends of the connecting sleeve are fixedly connected to the arc-shaped rod, a connecting block is fixed on the arc-shaped rod, a through hole is provided on the connecting block, a support column is installed in the through hole, a steering wheel is fixed on the upper end of the support column, and a guide wheel is fixed on the lower end of the support column. The angle of the guide wheel can be flexibly adjusted by turning the steering wheel, so as to accurately control the running direction of the device.

[0013] Preferably, a universal wheel is fixed to the bottom of the protective shell, and the universal wheel is located on the side of the protective shell close to the clamping mechanism. A one-way wheel is also fixed to the bottom of the protective shell, and the one-way wheel is located on the side of the protective shell away from the clamping mechanism. The universal wheel makes direction adjustment easy and convenient, while the one-way wheel ensures that the device can stably move in a predetermined direction, effectively preventing the occurrence of lateral deviation, and improving the stability and accuracy of the overall operation.

[0014] A method for using a wire guide device for circuit detection comprises the following steps:

[0015] (1) Clamping and fixing: Place the connector of the wire to be tested on the supporting crossbar, turn the adjustment knob, and control the clamping rod to clamp the wire to be tested;

[0016] (2) Adjust the position: control the telescopic length of the clamping rod in the clamping cylinder to deliver the connector of the wire to be tested to the entrance of the guide;

[0017] (3) Testing wires: Pull the wire to be tested so that it passes through the testing contacts from beginning to end to complete the testing of the wire.

[0018] It can be seen from the above technical solutions that the advantages of the present invention are: the supporting crossbar can support the wire to be tested, and the clamping rod can firmly clamp the wire and retract in the clamping tube, ensuring that the wire to be tested is smoothly and accurately fed between the two guide shielding plates. The guide shielding plate not only accurately guides and limits the travel path of the wire, so that it always remains within the effective detection range of the detection contact, but also effectively shields and isolates interference from other wires, thereby greatly improving the accuracy and reliability of the detection. In summary, the device guides and limits the wire to be tested to ensure that it is within the effective detection range of the detection contact, thereby avoiding missed detection; at the same time, the guide shielding plate can effectively shield other wires to prevent misdetection, thereby ensuring the accuracy of the measurement results.

[0031] like Figure 4As shown, a connecting sleeve 4 is provided on the arc rod 3, and both ends of the connecting sleeve 4 are welded to the arc rod 3. A gear 7 is installed inside the connecting sleeve 4, and an adjusting knob 5 is provided above the connecting sleeve 4.
