Description

Technical Field

[0001] The present invention relates to the field of instrument room detection, and particularly to a test system and a test method for testing the instrument room of a ring main unit. Background Art

[0002] In the power transmission and transformation system, the 10kV ring main unit is a very important electrical equipment in the power system. As a typical terminal distribution equipment, it is widely used in the power system and various industrial users. It is an indispensable product in the smart grid and is directly related to the safe and reliable operation of the power grid. At present, the existing domestic ring main units mainly include gas-insulated ring main units, solid-insulated ring main units, etc.

[0003] The structure of the gas-insulated ring main unit mainly includes a gas tank, a mechanism room, a cable room, an instrument room, etc. During the production process, the assembly sequence is to first assemble the gas tank, the mechanism room, and the cable room into a whole to form the main body of the cabinet, then assemble the instrument room on the main body of the cabinet, and then complete the wiring and testing work between the instrument room and the main body of the cabinet.

[0004] During the above-mentioned test of the instrument room, it needs to be kept stable, otherwise it will affect the accuracy of the test results. The traditional fixing method cannot well adapt to instrument rooms of different sizes and shapes, or the instrument room may shift due to vibration or other reasons during the test. The previous test equipment may only be able to test some functions of the instrument room, and cannot comprehensively test the sockets at the top and bottom and the switches on the front at the same time, and cannot meet the complex test requirements of the ring main unit instrument room. If the traditional linear conveying method is adopted, a large space is required to arrange the test equipment and the conveying channel, and there may be waiting time during the conveying process, resulting in low test efficiency. Summary of the Invention

[0005] The present invention provides a test system for the instrument room of a ring main unit. The system is based on a flow production detection and test operation, with high production efficiency, high automation work accuracy, no influence of human factors, stable inspection results, and high reliability.

[0006] The system includes: A conveying device, on which there is carried an instrument room fixing tooling for fixing the instrument room to be tested, and the conveying device drives the instrument room fixing tooling to move along a first direction; The instrument room fixing tooling includes a lifting component and a clamping component. The clamping component is located above the lifting component. The lifting component supports the bottom of the instrument room to be tested, and the clamping component clamps both sides of the instrument room to be tested; The detection and testing device is arranged on one side of the conveying device. The detection and testing device includes a first plugging device, a switch driving device, and a second plugging device arranged in sequence from top to bottom. The first plugging device and the second plugging device can respectively cooperate with the socket connectors at the top and bottom of the instrument room to be tested. The switch driving device can operate the switch on the front of the instrument room to be tested. The first plugging device and the second plugging device are connected to the test master machine.

[0007] It can be seen from the above technical solutions that the advantages of the present invention are as follows: In the present system, the conveying device drives the fixture for fixing the instrument room to move in the first direction, realizing the automatic conveying of the instrument room to be tested. The detection and testing device is connected to the test master machine, automatically completing the plugging and switch operations with the instrument room. The lifting component of the fixture for fixing the instrument room can be adjusted according to the height of the instrument room, supporting the bottom of the instrument room, and the clamping components clamp the instrument room from both sides to ensure its stable fixation during the test.

[0008] The detection and testing device is designed with a first plugging device, a switch driving device, and a second plugging device arranged in sequence from top to bottom, which can cooperate with the socket connectors at the top and bottom of the instrument room and the switch on the front at the same time to achieve comprehensive testing. The conveying device adopts a circular layout of a first-layer conveying component and a second-layer conveying component. The lifting and conveying component realizes the connection between the two layers, effectively utilizing the space, reducing the waiting time during the conveying process, and improving the testing efficiency. The automated conveying and testing processes greatly reduce the testing time and improve the testing efficiency. Moreover, the stable fixture for fixing the instrument room and the comprehensive testing function ensure the accuracy and reliability of the test results, and can timely detect problems existing in the instrument room. The circular conveying layout effectively utilizes the testing space, making the layout of the testing system more compact and reasonable, and reducing the floor area occupied by the equipment.

The second pulley 245 is fixedly installed on the first lead screw 248 and is in V-belt drive cooperation with the first pulley 244 (the V-belt is not shown in the figure for clear display of the first pulley and the second pulley). When the first pulley 244 rotates, it can drive the second pulley 245 to rotate, and then drive the first lead screw 248 to rotate. The first lead screw 248 is installed on the sixth support 253 and can rotate relative to the sixth support 253. One end of the first lead screw 248 is connected to the second lead screw 249 through the first coupling 250. The end of the second lead screw 249 away from the first lead screw 248 is installed on the seventh support 254 and can rotate relative to the seventh support 254. The thread helix direction of the second lead screw 249 is opposite to that of the first lead screw 248.

[0051] Both ends of the first slide rail 251 and the second slide rail 252 are installed on the sixth support 253 and the seventh support 254. The first slide table 246 is installed on the first slide rail 251 and the second slide rail 252 and is connected to the nut seat of the first lead screw 248, and thus is in motion cooperation with the first lead screw 248. When the first lead screw 248 rotates, the first slide table 246 moves horizontally; the second slide table 247 is installed on the first slide rail 251 and the second slide rail 252 and is connected to the nut seat of the second lead screw 249, and thus is in motion cooperation with the second lead screw 249. When the second lead screw 249 rotates, the second slide table 247 moves horizontally. And due to the different helix directions of the first lead screw 248 and the second lead screw 249, the first slide table 246 and the second slide table 247 will approach or move away from each other during movement. There are two clamping jaws 255 in total, which are respectively fixedly installed on the first slide table 246 and the second slide table 247 by screws, and the surfaces of the two clamping jaws 255 are arranged opposite to each other. Rubber pads 256 are provided on the surfaces of the clamping jaws 255, which can increase the contact friction with the instrument chamber and make the clamping condition of the clamping jaws safer.

[0052] The working method of the instrument chamber fixing tooling is as follows: Drive the first motor 212, the first motor 212 drives the first gear 214 to rotate, and then drives the second gear 215 and the rotating shaft 216 to rotate. Since the rotating shaft 216, the rotating disk 217 and the instrument chamber support 219 are relatively fixed, the instrument chamber support 219 is driven to rotate, so that the instrument chamber fixed on the instrument chamber support 219 makes a rotating motion, and the instrument chamber reaches the desired rotation angle position, such as the position that is easy for the detection and testing device 4 to perform port plugging; Drive the first cylinder 232, so that the first cylinder rod 233 makes a telescopic motion, and then drives the bending support 234 and the instrument chamber to move vertically up and down, so that the instrument chamber reaches the desired height position; Drive the second motor 243, drive the first belt pulley 244, the second belt pulley 245, the first lead screw 248, the first coupling 250, and the second lead screw 249 to rotate. Since the helix directions of the two lead screws are different, the first slide table 246 and the second slide table 247 make horizontal motions in different directions, and then the two clamping jaws 255 approach or move away from each other, realizing the work of clamping and fixing the instrument chamber or releasing the clamping force. Through the cooperation of the rotating component 22, the lifting component 23 and the clamping component 24, the instrument chamber can be moved to the required positions under different working conditions. And the clamping component 24 can freely adjust the clamping width, and can realize the clamping and fixing work of instrument chambers of different models and sizes, improving the flexibility of the device.

The eleventh motor 472 drives the transmission 473, which can then cause the ninth connecting rod 474 to swing. There are six tenth connecting rods 475. On both sides of each ninth connecting rod 474, two tenth connecting rods 475 are respectively assembled through ball pins. The swing of the ninth connecting rod 474 can drive the tenth connecting rod 475 to move.

One end of the second coupling 477 is installed on the output shaft of the twelfth motor 476, and the other end is installed on the eleventh connecting rod 478. The inside of the eleventh connecting rod 478 is a hollow structure. One end of the twelfth connecting rod 479 is installed on the third coupling 480, and the other end is assembled in the inner cavity of the eleventh connecting rod 478. The twelfth connecting rod 479 can slide relative to the eleventh connecting rod 478, but the two will not rotate relative to each other (for example, through the form of spline fitting). One end of the third coupling 480 is installed on the twelfth connecting rod 479, and the other end is fixedly connected to the clamping plate support 482. The seventeenth support 481 is respectively connected to the six tenth connecting rods 475 through ball hinges around it, thereby establishing a motion connection between the seventeenth support 481 and the six tenth connecting rods 475.

The distance between the first clamping plate 483 and the second clamping plate 484 in the static state is slightly smaller than the thickness of the knob of the knob switch 13 in the instrument room.

[0067] Drive the three eleventh motors 472, and drive the three groups of ninth connecting rods 474 and tenth connecting rods 475 to move through the transmissions 473, thereby realizing the movement of the seventeenth support 481 in the spatial direction. When the seventeenth support approaches or moves away from the bracket 471, it will cause the twelfth connecting rod 479 to extend into or out of the eleventh connecting rod 478. Drive the twelfth motor 476, and successively drive the second coupling 477, the eleventh connecting rod 478, the twelfth connecting rod 479, the third coupling 480 and the clamping plate support 482 to rotate, thereby causing the switch operating mechanism to rotate.

[0068] Semicircular notches are respectively provided in the middle of the joints between the first clamping plate 483 and the second clamping plate 484 to facilitate the extension of the fourth cylinder rod 488. Rectangular protrusions facing forward (i.e., toward the instrument compartment) are respectively provided on both sides of the ends of the first clamping plate 483 and the second clamping plate 484. The outer corners of the rectangular protrusions are rounded so that they can touch the toggle switch 14 in the instrument compartment. The first clamping plate 483 and the second clamping plate 484 cooperate with each other to operate the three switches of button, knob, and toggle, realizing a three-in-one function.

[0069] There are eight compression springs 486. On both sides of the first clamping plate 483 and the second clamping plate 484, each connecting bolt 485 is sleeved with a compression spring 486, so that the first clamping plate 483 and the second clamping plate 484 can be elastically squeezed on the clamping plate support 482. The fourth cylinder 487 is fixedly installed on the clamping plate support 482. The fourth cylinder rod 488 can be extended or retracted under the drive of the fourth cylinder 487. When the fourth cylinder rod 488 is extended, its height is greater than the height of the rectangular protrusion of the clamping plate. When the fourth cylinder rod 488 is retracted, its height should be lower than the height of the inner surface of the first clamping plate 483 and the second clamping plate 484, and will not affect the opening and closing of the knob. The outer diameter of the fourth cylinder rod 488 is smaller than the outer diameter of the push button switch 12 of the instrument room.

[0070] The working method of the switch driving device 47 is as follows: The three eleventh motors 472 are driven to move the ninth connecting rod 474 and the tenth connecting rod 475 through the gearbox 473. The three groups of the ninth connecting rod 474 and the tenth connecting rod 475 cooperate with each other, thereby realizing the movement of the seventeenth support 481 in the space, and finally stopping the first clamping plate 483 and the second clamping plate 484 in front of the switch on the surface of the instrument room; The button switch 12 is opened and closed by driving the fourth air cylinder 487 to extend and retract the fourth air cylinder rod 488, thereby closing the button switch 12; the fourth air cylinder 487 is driven again to extend and retract the fourth air cylinder rod 488, thereby opening the button switch 12; Knob switch 13 opening and closing action: When the first clamping plate 483 and the second clamping plate 484 stop in front of the knob switch 13, the eleventh motor 472 is continuously driven, so that the first clamping plate 483 and the second clamping plate 484 continue to move forward and touch the knob switch 13, and then the knob slowly enters the interior between the first clamping plate 483 and the second clamping plate 484. Due to the action of the compression spring 486, the first clamping plate 483 and the second clamping plate 484 are spread apart by the knob, but are still pressed against the knob. The twelfth motor 476 is driven to rotate the second coupling 477, the eleventh connecting rod 478, the twelfth connecting rod 479, the third coupling 480 and the clamping plate support 482, and then the first clamping plate 483 and the second clamping plate 484 are rotated. Thus, the knob switch 13 is driven to different gears.

[0071] The operation of the toggle switch 14: After the first clamping plate 483 and the second clamping plate 484 stop directly in front of the rotary switch 13, continue to drive the eleventh motor 472, so that the first clamping plate 483 and the second clamping plate 484 continue to move forward and thus touch the toggle switch 14, thereby pressing the toggle switch 14 to open and close.

[0072] The first clamping plate 483 and the second clamping plate 484 achieve a three-in-one control function, improving the flexibility of the device for detection and testing. By controlling the opening and closing of the push-button switch 12, the rotary switch 13, and the toggle switch 14, the control of electrical components is realized, and then the detection and testing of the entire ring main unit are achieved.

[0073] Through the detection and testing device 4, the data transmission, debugging, and testing in the instrument room can be automated, realizing the automated operation of the detection and testing in the instrument room, greatly improving the production efficiency, and having high automation work accuracy, no influence of human factors, stable inspection results, and high reliability.
