Description
Technical Field
[0001] The invention relates to the technical field of industrial robots, and in particular provides an automatic wire connection and disconnection robot for high-voltage transformer testing. Background Art
[0002] High-voltage transformers are transformers that are suitable for converting high voltage into low voltage or high current into low current in 1kv to 220kv power systems for measurement, protection, and use. They are generally divided into 3kv, 6kv, 10kv, 35kv, 66kv, 110kv, and 220kv. They are mainly used to monitor the operation of electrical equipment and control systems in AC circuits (usually the primary winding is called the primary winding or primary winding, and the secondary winding is called the secondary winding or secondary winding). They are used to supply power to the voltage coil and current coil of the measuring instrument and relay, respectively, to correctly reflect the normal operation and fault conditions of the electrical equipment. The accuracy of the measuring instrument and the reliability of the relay protection action are largely related to the performance of the transformer.
[0003] In actual applications, high-voltage transformers have a wide range of applications, large annual purchase volumes, and numerous model parameters. The quality of transformers currently used in distribution network lines varies greatly. If full performance quality inspection is not carried out before commissioning, the quality is difficult to guarantee.
[0004] At present, the full performance test of high-voltage transformers is still in a manual state, and the test connection and disconnection are completed manually. The test process requires repeated disconnection and connection according to different test items. There are problems such as large workload, high professional requirements, and great safety hazards. Due to the different wiring methods of different experimental sub-items and the thicker and heavier cables, the operation is cumbersome, time-consuming and labor-intensive, with high labor intensity and low efficiency.

[0060] The primary terminal wiring mechanism comprises: a high voltage line wiring mechanism and a terminal pressing mechanism;
[0061] The secondary terminal wiring mechanism includes a secondary terminal mechanical arm 3 and a secondary terminal wiring terminal 4.
[0062] By decomposing the primary terminal wiring mechanism into two parts, the high-voltage line wiring mechanism and the terminal pressing mechanism, the high-voltage terminal is only responsible for connecting to the primary end of the high-voltage transformer, and the clamping action is performed by the terminal pressing mechanism, which improves the safety of operation and can effectively improve the efficiency of wiring and disconnection.
[0063] The structure of the high-voltage line connection mechanism includes a primary-end mechanical arm 5, a high-voltage line 6 and a connection terminal 7, wherein one end of the high-voltage line 6 is connected to a high-voltage power supply, and the other end is fixed to the primary-end mechanical arm 5 through an insulator, and the connection terminal 7 is connected to the end of the high-voltage line 5, and the connection terminal 7 extends out of the primary-end mechanical arm 5; wherein the shape of the connection terminal 7 matches the shape of the primary end of the high-voltage transformer.

[0066] The horizontal moving mechanism 8 can perform two-dimensional movement in the horizontal direction under the control of the robot control system;
[0067] The vertical lifting mechanism 9 can perform one-dimensional movement in the vertical direction under the control of the robot control system.
[0068] The robot also includes a video positioning module, which uses image processing technology through the camera 11 to locate and control the high-voltage transformer terminal, the primary terminal wiring mechanism, and the secondary terminal wiring mechanism carried by the mobile platform 1, and identifies the position and posture of the target object by analyzing the real-time video of the surrounding environment, and feeds back the acquired information to the robot control system to achieve the positioning and movement of the target object.
[0069] The video positioning module adopts dual-camera positioning, using two cameras 11 to determine the position and direction of the object, and calculates the distance and direction of the object relative to the camera by comparing the position, size and angle of the object captured by the two cameras.
[0070] Dual-camera positioning can improve the accuracy and stability of positioning because it can use information from multiple angles to perform positioning, avoiding errors and obstacles that may occur with a single camera. The implementation process is as follows:
[0071] The position of one of the cameras 11 - 1 is used as the origin to establish a camera coordinate system, and the spatial coordinates of the high-voltage transformer terminal, the primary terminal wiring mechanism, and the secondary terminal wiring mechanism are identified;
[0072] A high-voltage transformer primary wiring terminal (25, 33, 10), a high-voltage transformer secondary wiring terminal (20, 28, 8), a primary terminal wiring mechanism (13, 24, 20), and a secondary terminal wiring mechanism (11, 20, 16);
[0073] The position of another camera 11-2 is used as the origin to establish a camera coordinate system, and the spatial coordinates of the high-voltage transformer terminal, the primary terminal wiring mechanism, and the secondary terminal wiring mechanism are identified;

[0078] After the robot control system locates the primary terminal of the high-voltage transformer to be tested through the video positioning module, it controls the primary end mechanical arm 5 of the high-voltage wire connection mechanism to operate and move the terminal 7 to the primary terminal of the high-voltage transformer to be tested;
[0079] The robot control system controls the terminal pressing mechanism to move to the terminal 7 position, and connects the terminal 7 of the high-voltage line connection mechanism with the primary terminal of the high-voltage transformer to be tested.

[0082] The primary terminal wiring mechanism is composed of two or three independent mechanisms, which can adapt to a high-voltage transformer with two or three wiring terminals at the primary end. The setting of the primary terminal wiring mechanism is determined according to the number of terminals at the primary end of the high-voltage transformer. When the number of primary terminal wiring mechanisms exceeds the number of terminals at the primary end of the high-voltage transformer, the number of primary terminal wiring mechanisms in use can be controlled by the robot control program.
[0083] The workflow of the robot control system is as follows:
[0084] After the high-voltage transformer to be tested is placed on the mobile platform 1, the robot control system controls the mobile platform to operate;
[0085] When the high-voltage transformer carried by the mobile platform 1 moves to the bottom of the primary terminal wiring mechanism, the robot control system controls the mobile platform to stop, and controls the wiring terminal 7 of the high-voltage wire wiring mechanism of the primary terminal wiring mechanism to move to the primary wiring terminal position of the high-voltage transformer;
[0086] The robot control system controls the terminal pressing mechanism to move to the top of the terminal 7 of the high-voltage wire connection mechanism, and after positioning, moves downward to press the terminal 7 of the high-voltage wire connection mechanism and the primary terminal of the high-voltage transformer tightly through the insulating terminal 10;
[0087] The robot control system controls the secondary terminal wiring mechanism to move to the secondary terminal position of the high-voltage transformer and press it;
[0088] The high-voltage line connection mechanism is energized for testing;
[0089] The data acquisition and analysis module collects the voltage and current signals of the primary and secondary ends of the high-voltage transformer, and summarizes and analyzes them;
[0090] After the analysis is completed, the high-voltage wire connection mechanism is powered off, and the robot control system controls the terminal pressing mechanism, so that the high-voltage wire connection mechanism and the secondary terminal connection mechanism are raised, and the connection with the primary terminal and the secondary terminal of the high-voltage transformer is disconnected;
