Description

Technical Field

[0001] The utility model relates to the technical field of testing and detecting safety tools for electric power operations, in particular to a plugging and unplugging detection device for a bypass cable connector. Background Art

[0002] During bypass operation, the bypass cable introduces current in parallel with the cable line, so that the power supply line is not interrupted, and the power is transferred to the load connected to the bypass cable to ensure that the load is powered and the equipment to be repaired can be powered off or repaired with power. Bypass cables play an important role in maintaining power facilities, improving operational efficiency, and ensuring power grid security. They are important tools to ensure the safety and normal operation of power systems. Therefore, before the new bypass cable is put into use, in order to verify whether the product can meet all the requirements of the technical specifications, it is necessary to conduct type tests on it according to relevant standards.

[0003] According to the requirements of the standard GB / T 34577-2017 Technical Guidelines for Distribution Line Bypass Operations, the mechanical life of the bypass cable connector should be no less than 1,000 cycles (docking and separation is one cycle).

[0004] According to the requirements of standard DL / T 2555.1-2022 Distribution Line Bypass Operation Tools and Equipment Part 1: Bypass Cables and Connectors, the insertion force of the bypass cable male / female connector should not exceed 90N, and the extraction force should not exceed 80N.

[0005] Before the implementation of the industry standard DL / T 2555.1-2022 Distribution Line Bypass Operation Tools and Equipment Part 1: Bypass Cables and Connectors, the mechanical life plug-in and pull-out tests of bypass cable connectors in some testing agencies were mainly completed manually by testers. This was not only time-consuming and inefficient, but also unable to guarantee the effectiveness of each plug-in and pull-out test in repeated multiple tests, which posed a considerable challenge to the accurate measurement of the actual performance of the product. After the implementation of the industry standard, requirements were put forward for the insertion force and extraction force of the bypass cable connector. Testers could not simply judge whether the performance of the bypass cable connector met the standards based on their own subjective experience. They needed to use an automated plug-in and pull-out device that could measure the insertion force and extraction force when the bypass cable was connected to assist in the detection. Although the existing plug-in and pull-out force test device for bypass cable connectors can meet most test requirements, it still has some shortcomings. The following are the main problems:

[0006] (1) The test scenario does not match the actual use scenario of the bypass cable connector. In actual use, the bypass cable is usually integrated into a system or device, and a tight connection is formed between the connector and the cable. Some testing agencies separate the connector for performance testing when conducting plug-in and pull-out force tests on bypass cable connectors, which is inconsistent with actual use. This may lead to differences between the test performance and actual performance of the connector, affecting the correct evaluation of product quality.

[0007] (3) The cost of replacing and repairing force sensors is high. The standard GB / T 34577-2017 Technical Guidelines for Distribution Line Bypass Operations only requires a mechanical life test. The standard DL / T 2555.1-2022 Distribution Line Bypass Operation Tools and Equipment Part 1 adds force requirements for plugging and unplugging on this basis. For tests that simply detect the mechanical life of bypass cable connectors, the inability to remove the force sensor will cause the life of the force sensor sensing element to be greatly reduced, and the long-term stability of the force sensor will be damaged. Failure to replace or recalibrate in time will cause the test result error to increase, affecting the correct assessment of product quality. At the same time, due to the shortened life of the sensing element, the cost of frequently replacing or repairing the sensor will increase, increasing the maintenance cost and time cost of the test equipment.

[0008] (4) The device is large and lacks portability. In some scenarios where it is inconvenient to send the device for inspection or it is urgently needed for use after on-site inspection, the existing bypass cable connector plug-in force test equipment is large in size and lacks portability, making it difficult to perform portability tests and on-site inspection tests, which limits the flexibility and efficiency of on-site work. Secondly, bulky test equipment may face many restrictions during transportation, such as being unable to pass through narrow passages or being unable to be placed in regular vehicles, thereby increasing the complexity and cost of transportation. In addition, for laboratories with limited available space, bulky equipment will limit the use of laboratory space and cause space waste. Utility Model Content

The status indicator light 113 is used to display whether the device is working and whether there is any abnormality in the work.

The main function of the fixing fixture 3 is to constrain the degree of freedom of the bypass cable connector or the joint of the bypass cable, and the sample position can also be fine-tuned by guide rails, hand screws, etc., to achieve multi-size and multi-type sample testing.

[0044] In this embodiment, the structure of the movable clamp 4 can refer to the structure of the fixed clamp 3, and the structure of the movable clamp 4 will not be described in detail here.

[0045] Continue to see Figure 4 The locking member 8 may include: two locking screws 81; wherein the two locking screws 81 are respectively arranged on both sides of the longitudinal direction of the fixed clamp 3 or the movable clamp 4, and each locking screw 81 is arranged on the longitudinal movable guide rail 7 in a position-adjustable manner along the length direction of the longitudinal movable guide rail 7, and is used for the two locking screws 81 to be adjusted from the longitudinal sides of the fixed clamp 3 or the movable clamp 4 (such as Figure 4 The fixed clamp 3 or the movable clamp 4 is clamped (on the left and right sides as shown).

[0046] Specifically, take the fixing fixture 3 as an example. Figure 4 As shown, the two locking screws 81 can be coaxially arranged on the left and right sides of the fixing fixture 3, and the left and right ends of the longitudinal movable guide rail 7 are extended with fixing plates 71, the two locking screws 81 are respectively penetrated through the two fixing plates 71 and are respectively threadedly connected to the two fixing plates 71, and the position of the adjustable locking screw 81 close to the end of the fixing fixture 3 can be adjusted so that when the fixing fixture 3 is adjusted longitudinally, i.e., the y-axis position is adjusted, the adjustable locking screw 81 is loosened to adjust the longitudinal position of the fixing fixture 3, and after the fixing fixture 3 is adjusted into place, the adjustable locking screw 81 is tightened, i.e., the ends of the two adjustable locking screws 81 are pressed and contacted on the fixing fixture 3 to achieve locking of the fixing fixture 3, so that the bypass cable connector or the connector of the bypass cable can be kept fixed during the plug-in and pull-out test. The end of the adjustable locking screw 81 close to the fixing fixture 3 may be provided with a locking plate to increase the locking contact area between the end of the adjustable locking screw 81 close to the fixing fixture 3 and the fixing fixture 3 .

[0047] Continue to see Figure 1The lateral movement driving assembly 10 may include: a lateral driving motor (not shown in the figure), a transmission wheel 102, which is connected to the power output end of the lateral driving motor and is used to rotate coaxially with the lateral driving motor; the two ends of the transmission rod 103 are respectively hinged to the transmission wheel 102 and the movable clamp 4, and are used to convert the rotation of the transmission wheel 102 with the lateral driving motor into the lateral movement of the movable clamp 4.

[0048] Specifically, the transverse drive motor can be arranged inside the housing 1, and a transmission shaft 101 is arranged on the power output end of the transverse drive motor. The transmission shaft 101 is rotatably arranged in the top shell of the housing 1 and the power output end is extended to the outside of the housing 1. The transmission wheel 102 is arranged at the end of the transmission shaft 101 outside the housing 1 (such as Figure 1 The top end shown in FIG. 1 ) and the transmission wheel 102 and the transmission shaft 101 can be coaxially arranged so that under the drive of the transverse drive motor, the transmission wheel 102 rotates synchronously with the transmission shaft 101 around the axis of the transmission shaft 101. The two ends of the transmission rod 103 are respectively hinged to the transmission wheel 102 and the movable fixture 4, so that a crank slider mechanism is formed between the transmission wheel 102, the transmission rod 103 and the movable fixture 4 to convert the rotation of the transmission wheel 102 into the transverse movement of the movable fixture 4.

[0049] Continue to see Figure 1 The transmission rod 103 includes: a vertical connecting rod 1031 and a horizontal hinge rod 1032; wherein the fixed end of the vertical connecting rod 1031 (such as Figure 1 The bottom end shown in FIG. 100 is eccentrically disposed on the transmission wheel 102; one end of the horizontal hinged rod 1032 (as shown in FIG. Figure 1 The right end shown in FIG. 100 is connected to the connecting end of the vertical connecting rod 1031 (as shown in FIG. Figure 1 For example, the right end of the horizontal hinge rod 1032 may be provided with a rotating ring, which is rotatably mounted on the vertical connecting rod 1031, and the other end (as shown in FIG. Figure 1The left end of the movable clamp 4 is hingedly connected to the movable clamp 4 so that when the transmission wheel 102 rotates, the vertical connecting rod 1031 rotates synchronously around the axis of the transmission wheel 102, i.e., the axis of the transmission shaft 101, and can drive the horizontal hinged rod 103 to be linked, so as to drive the movable clamp 4 to slide along the lateral movable guide rail 9, thereby realizing the lateral movement of the movable clamp 4. That is to say, when the transmission wheel 102 rotates, it drives the transmission rod 103 to make a circular motion, and the transmission rod 103 drives the movable clamp 3 to make a reciprocating motion on the transverse sliding guide rail 9. When the transmission rod 103, especially the vertical connecting rod 1031, moves to the left side of the transmission shaft 101, the movable clamp 3 moves to the leftmost side of the transverse sliding guide rail 9, so as to realize the insertion of the bypass cable connector or the insertion between the bypass cable connector and the bypass cable joint; when the vertical connecting rod 1031 moves to the right side of the transmission shaft 101, the movable clamp 3 moves to the right side of the transverse sliding guide rail 9, so as to realize the removal of the bypass cable connector or the removal of the bypass cable connector and the bypass cable joint.

[0050] In this embodiment, the controller may include: a central processing chip, a power module and a heat dissipation module. The central processing chip is responsible for processing the operating data and the operating status of the control device, receiving and processing the instructions received by the device, and driving the motor according to the preset algorithm and logic to realize the programmed and automated detection of the plug-in and pull-out force test of the bypass cable connector. The power module provides stable power for the equipment to ensure the normal operation of the equipment. The lateral drive motor is the executive component of the controller, which drives the transmission module to realize the detection work according to the instructions issued by the central processing chip. The heat dissipation module is responsible for ensuring the stable operating temperature of each component in the control module. It is composed of heat dissipation fins and fans, which quickly dissipate the generated heat to prevent the control module from overheating and affecting its performance and stability.

[0051] The working principle of the device is as follows: after the bypass cable and the alignment connector are fixed, the male end and the female end of the bypass cable connector can be clamped respectively through the fixed clamp 3 and the movable clamp 4, or the joint of the bypass cable and the bypass cable connector can be clamped respectively through the fixed clamp 3 and the movable clamp 4. During the alignment adjustment process: the height of the fixed clamp 3 can be fine-tuned in the z-axis direction through the height adjustment platform 2, and the fixed clamp 3 and the movable clamp 4 can be moved longitudinally along the corresponding longitudinal movable guide rail 7, that is, the y-axis movement, to achieve y-axis fine-tuning; turn on the power switch 14, and the test program and the number of tests can be set through the control panel 11, the test speed can be set through the speed control knob 112, and the device can be observed to be in normal operation through the status indicator light 113. The lateral drive motor drives the transmission shaft 101 and the transmission wheel 102 to perform periodic rotational motion, and the transmission rod 103 arranged on the transmission wheel 102 performs reciprocating motion, and the movable fixture 4 on the right side is driven to move left and right on the lateral sliding rail 9. When the movable fixture 4 moves to the left, the bypass cable connector is inserted and removed with the bypass cable connector fixed on the other side fixed fixture 3. The force sensor fixed on the fixture connector 6 records the force value of insertion and removal, and feeds back to the control panel 11. After the test is completed according to the preset program, the control panel 11 automatically transmits the data to the printing module 114, and prints out the number of insertion and removal, the maximum insertion force, and the removal force of the bypass cable connector during the test. The test personnel can check the status of the bypass cable connector at this time to determine whether it meets the standard requirements.

[0052] In this embodiment, for scenarios requiring on-site testing or mobile transportation of equipment, the device of the utility model can disperse the various components of the device into modules that are easier to move and transport by disassembling the transmission rod 103, the movable clamp 4, the fixed clamp 3, the clamp connector 6, the height adjustment platform 2, the detachable platform 5, etc., to meet diversified testing needs; for tests that do not detect the plugging and unplugging force of the bypass cable connector but only detect mechanical properties, the device of the utility model removes the force sensor fixed in the detachable platform 5 and selects a program for only mechanical performance testing in the control panel 11, so that the force sensor does not participate in the test process, the test loss of the sensor element is reduced, the life of the force sensor is extended, and the accuracy of the test data is improved.

[0053] In summary, the bypass cable connector plugging and unplugging detection device provided in this embodiment can adjust the height of the fixed fixture 3 through the height adjustment platform 2, and the male end and the female end of the bypass cable connector can be clamped respectively by the fixed fixture 3 and the movable fixture 4. The fixed fixture 3 and the movable fixture 4 can also clamp the joint of the bypass cable and the bypass cable connector respectively. The height relative position adjustment between the male end and the female end of the bypass cable connector can be achieved by adjusting the height of the fixed fixture 3 through the height adjustment platform 2, and the height relative position adjustment between the joint of the bypass cable and the bypass cable connector can also be achieved; through the lateral movement of the movable fixture 4, the male end or female end of the bypass cable connector is made to lean against the female end or male end clamped by the fixed fixture 3, that is, the male end or female end of the bypass cable connector is driven to move to the left by the movable fixture 4, that is, the movement in the x-axis direction is achieved to achieve the plugging and unplugging test of the bypass cable connector. At the same time, the device also has the following effects:

[0054] First, in this embodiment, the bypass cable connector plug-in and pull-out detection device is a horizontal plug-in and pull-out force testing device. It is not necessary to separate the connector from the bypass cable for testing. It is as close to the actual use scenario of the connector as possible. The plug-in and pull-out mechanical life and plug-in and pull-out force performance tests are performed while the connector remains tightly connected to the bypass cable, so that the detection test is more in line with the working conditions and the detected product data is more reliable.

[0055] Second, in this embodiment, the force sensor is assembled and disassembled through a screw structure to meet the requirements of different types of samples for different test standards, while enhancing the long-term stability of the force sensor, extending the service life of the sensor element, and reducing the maintenance cost and time cost of the test equipment.

[0056] Third, compared with the existing common bypass cable connector plug-in force test device, this device has the characteristics of small size and light weight. At the same time, the utility model designs the lateral moving drive component, fixed fixture 3 and movable fixture 4 as detachable structures, making it easier to carry and transport, improving the flexibility, efficiency and cost-effectiveness of the test work, and the product has a wider range of applications. For scenarios where it is inconvenient to send samples for testing and urgently need on-site testing, this device has obvious advantages.
