Technical Field

[0002] At present, gas insulated switchgear (GIS) has been widely used in substations due to its advantages of small footprint, high reliability, short installation cycle, and long maintenance cycle. The quality of GIS pot insulators has a decisive influence on the overall quality of GIS. As the most important insulating component in GIS, pot insulators play the role of electrical insulation, gas sealing, shell reinforcement and support. In actual production and live operation, due to improper product production process control and uneven distribution of tensile stress of bolt fasteners at the flange, the pot insulators are deformed and cracked, which leads to GIS leakage, partial discharge and even insulator surface flashover and other faults, resulting in large-scale power outages. Therefore, defect detection of pot insulators is of great significance to the safe operation of GIS. Since there may be multiple defects in the insulator at the same time, it is necessary to manually perform multiple tests on a single insulator. At present, since there is no device that can simultaneously realize the linkage detection of the galvanized layer and load performance of the insulator, the insulator detection still needs to be completed manually, resulting in the phenomenon of high labor costs in the detection of insulators. Summary of the invention

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] This embodiment provides an insulator multi-parameter linkage detection device, such as Figure 1-6 As shown, the detection device includes a cabinet provided with a control module and a defect detection component 2 and a performance detection component 3 arranged in the cabinet in a staggered manner along the height direction of the cabinet, the defect detection component 2 and the performance detection component 3 are connected through a circulation component 4, and the circulation component 4 drives and guides a turnover box 1 pivotally provided with an insulator to pass through the defect detection component 2 and the performance detection component 3 in sequence to detect the galvanized layer thickness and mechanical load performance of the insulator, thereby realizing automatic detection of the creepage distance, galvanized layer thickness, and mechanical damage load strength of the insulator, and has the advantages of high detection efficiency, low detection cost, and safe and reliable application.

[0032] Specifically, the defect detection component 2 and the performance detection component 3 arranged in the cabinet body in a staggered manner along the cabinet body height direction are connected through a circulation component 4, and the circulation component 4 includes a silo and a push rod matched therewith. Figure 5As shown, the silo includes a first silo 41 and a second silo 42, and the silo outlet of the first silo 41 and the silo inlet of the second silo 42 are arranged adjacent to the defect detection component 2. Since the top of the silo is set as the silo inlet and the bottom side thereof is set as the silo outlet, the specific internal circulation path of the circulation component 4 includes: after the turnover box 1 is transferred from the silo inlet of the first silo 41 along the silo inner cavity from top to bottom to the silo outlet, it is pushed by the first push rod 411 and moves a predetermined distance in the direction away from the silo outlet to the rotating base 21 of the defect detection component 2. After the defect detection component 2 has completed the detection, the second push rod 412 arranged at the silo inlet position of the second silo 42 extends to pull the turnover box 1 to the silo inlet of the second silo 42, and the turnover box 1 After being transmitted from top to bottom along the inner cavity of the silo from the inlet of the second silo 42 to the outlet of the second silo 42, it is pushed by the third push rod 421 and moved toward the outlet of the second silo to the jig chuck 34 of the performance detection assembly 3. The jig chuck 34 stretches or squeezes the insulator in the turnover box 1 under the control of the control module, and synchronously transmits the load performance data to the control module through the force sensor. After the load performance test is completed, the jig chuck 34 releases the insulator, and the third push rod 421 extends to push the turnover box 1 out of the detection device, and the linkage detection process ends.

[0033] In terms of the coordination between the components, the defect detection component 2 includes a rotating base 21 supporting the turnover box 1, a three-dimensional scanning module 22 and a galvanized layer detection sensor 23 arranged on the peripheral position of the rotating base. Since the input end of the defect detection component 2 is communicatively connected with the output end of the control module, in the detection state, the rotating base 21 drives the insulator in the turnover box 1 to rotate around its own axis, and cooperates to drive the three-dimensional scanning module 22 and the galvanized layer detection sensor 23 to perform parameter detection and return data signals to the control module. In addition, considering the diversity of the external dimensions of the insulator, the present embodiment sets the upper top plate 11, the lower bottom plate 12 and the column 13 supported between the upper top plate and the lower bottom plate 12 constituting the turnover box 1 into an adjustable structure, so that it has scalability along its own height direction to adapt to more insulators of different heights to improve the universality of the device. Furthermore, in order to make the insulators in the turnover box 1 rotate more flexibly driven by the rotating base 21, the present embodiment is provided with a bearing seat 14 for pivoting the insulators at the bottom of the upper top plate 11 and the top of the lower bottom plate. In addition, the present embodiment is also provided with a damper on the column 13. When the turnover box 1 slides downward, the damper can provide a buffering force for the turnover box 1 in the opposite direction of the sliding direction of the box body, so as to prevent the insulators from being damaged during the falling process of the turnover box 1 from top to bottom along the inner cavity of the silo to the silo outlet.

[0034] It should be noted that, during the zinc coating thickness detection process, since the zinc coating detection sensor 23 needs to be attached to the outer surface of the insulator during detection, and in order to ensure the comprehensive detection of the zinc coating on the outer surface of the insulator, the zinc coating detection sensor 23 needs to move along the height direction of the insulator during the rotation of the insulator. Therefore, in this embodiment, a position adjustment mechanism 231 for adjusting the two-dimensional movement degrees of freedom of the zinc coating detection sensor 23 in the height direction and the horizontal direction is also provided on the zinc coating detection sensor 23, such as Figure 3 shown.

[0035] The performance detection component 3 is arranged at the exit of the second silo 42, and its structure comprises a slide rail 31 fixed on the outer wall of the second silo 42, on which a slider 32 is slidably arranged, and the slider 32 moves up and down under the drive of a driving device 33, and the driving device 33 is a cylinder or a motor, which can drive a tooling chuck 34 connected to the bottom of the slider 32 to stretch or squeeze the insulator. In addition, since the input end of the performance detection component 3 is communicatively connected to the output end of the control module, and a force sensor is linked to the tooling chuck, the output end of the force sensor is connected to the input end of the control module. When the tooling chuck 34 stretches or squeezes the insulator, the force sensor can synchronously measure and transmit the mechanical damage load data of the insulator to the control module in real time to realize the automatic detection of the load performance of the insulator.

[0036] A detection method for an insulator multi-parameter linkage detection device according to this embodiment includes the following steps:

[0037] Step 1: Encapsulate the insulator in the turnover box 1 and place it in the circulation component 4, and move it to the rotating base 21 of the defect detection component 2;

[0038] Step 2: The control module drives the rotating base to rotate the insulator, and synchronously drives the three-dimensional scanning module 22 and the zinc coating detection sensor 23 to scan the external contour of the insulator, calculate and return the external dimensions, creepage distance and zinc coating thickness data of the insulator;

[0039] Step 3: The turnover box 1 is pushed along the circulation component 4 to the performance detection component 3, and the detection component 3 applies tension or pressure to the insulator and transmits back the mechanical damage load data of the insulator;

[0040] Step 4: The insulator that has completed the load performance test is sent out of the testing device, and the next insulator is packaged in the turnover box 1 and placed in the circulation assembly 4, and steps 1 to 3 are repeated for testing.

[0041] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
