Description
Technical Field
[0001] The invention belongs to the field of dry-type air-core reactor insulation detection, and in particular relates to dry-type air-core reactor insulation detection equipment. Background Art
[0002] A dry-type air-core reactor is a device that adjusts capacitance or inductance through the electromagnetic induction force of a coil. Its coil is insulated by air and does not require any insulating liquid. Therefore, it is also called a dry-type transformer. As an important device in the power system, the insulation performance of the dry-type air-core reactor directly affects the overall operating status of the equipment. When performing insulation testing on it, if there is some dirt attached to its surface, it may affect the test results. Therefore, it is also necessary to test its surface before performing insulation testing.

[0004] (1) When the device detects dirt on the surface of a dry-type air-core reactor, the accumulated height of the electric rotating disk, the buffer seat, the electric push rod, the second mounting plate and the infrared scanner is relatively high. When the gap at the detection entrance is relatively low, the device cannot pass through the gap normally.
[0005] (2) When the device is used for a long time, when the moving block moves on the screw rod, the moving block may rotate along with the screw rod, thereby reducing the detection accuracy of the device.
[0006] Therefore, we propose a dry-type air-core reactor insulation detection device to solve the defects of existing equipment. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In the scheme of the present invention:
[0019] 1. Through the detection mechanism set up, the function of detecting the debris on the surface of the dry-type air-core reactor is realized before the insulation test of the dry-type air-core reactor is carried out through the insulation tester body. In the detection mechanism, under normal conditions, the electric telescopic rod is placed horizontally. When performing insulation testing, the motor drives the screw rod to rotate, thereby moving the camera to the inside of the dry-type air-core reactor, and then the motor drives the connecting plate, the electric telescopic rod and the camera to rotate, so that it can move in a smaller gap, which is highly practical.
[0020] 2. By setting up the guide assembly, the stability of the moving block is improved. In the guide assembly, whenever the moving block moves, the guide block will slide inside the moving hole. At this time, the side wall of the guide block will fit with the inner wall of the moving hole, thereby preventing the moving block from rotating with the screw rod when the screw rod rotates.

DETAILED DESCRIPTION
[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0031] Example: Combination Figure 1 to Figure 6 As shown, this embodiment provides a dry-type air-core reactor insulation detection device, which includes an insulation detector body 1; a detection mechanism 2 is arranged outside the insulation detector body 1, and a guide component 3 is arranged inside the detection mechanism 2;
[0032] The detection mechanism 2 includes a placement frame 201, a moving frame 202, a screw rod 203, a motor 204, a moving block 205, a support portion 206, a rotating portion 207, a motor 208, an electric turntable 209, a connecting plate 210, an electric telescopic rod 211, a camera 212 and a display screen 213;
[0033] The placing frame 201 is arranged outside the insulation tester body 1, the moving frame 202 is bolted to the bottom of the placing frame 201, the screw rod 203 is rotatably connected to the inside of the moving frame 202, the motor 204 is bolted to the outer wall of the moving frame 202, the moving block 205 is threadedly connected to the outside of the screw rod 203, the support part 206 is bolted to the top of the moving block 205, the rotating part 207 is rotatably connected to the inside of the supporting part 206, and the motor 208 is bolted to the outer wall of the moving frame 202. It is connected to the side wall of the support part 206 and is coaxially arranged with the rotating part 207. The electric turntable 209 is bolted to the side wall of the rotating part 207. The connecting plate 210 is bolted to one side of the electric turntable 209. The electric telescopic rod 211 is bolted to the side wall of the connecting plate 210. The camera 212 is bolted to the output end of the electric telescopic rod 211. The display screen 213 is bolted to the side wall of the placement frame 201. The display screen 213 is electrically signal connected to the camera 212.
[0034] The screw rod 203 is coaxially arranged with the motor 204 and the motor 204 can drive the screw rod 203 to rotate, and the motor 208 can drive the rotating part 207 to rotate. When the dry-type air-core reactor is subjected to insulation inspection, the device is placed at a designated position, and then the motor 204, the motor 208, the electric turntable 209, the electric telescopic rod 211, the camera 212 and the display screen 213 are connected to an external battery, and then the motor 204 drives the screw rod 203 to rotate, thereby moving the moving block 205. When the moving block 205 moves to the dry-type air-core reactor, the moving block 205 moves to the dry-type air-core reactor. When observing the inner side of the dry-type air-core reactor, the motor 208 is started, so that the motor 208 drives the rotating part 207 to rotate ninety degrees, and then the electric turntable 209 and the electric telescopic rod 211 operate at the same time, thereby driving the camera 212 to rise and fall and rotate, so as to observe the condition inside the dry-type air-core reactor. Then the worker can observe through the display screen 213 whether there are some debris attached to the side wall of the dry-type air-core reactor to affect the detection result. If there are debris, the device can be taken out after cleaning, and the insulation detection can be performed on it through the insulation detection instrument body 1.
[0035] like Figure 5 As shown, the guide assembly 3 includes a moving hole 301 and a guide block 302. The moving hole 301 is opened at the bottom of the moving frame 202. The guide block 302 is bolted to the bottom of the moving block 205 and is slidably connected to the moving hole 301. When the moving block 205 moves, the guide block 302 will slide inside the moving hole 301, thereby preventing the moving block 205 from shaking when moving.
[0036] like Figure 5 As shown, a universal wheel 4 is bolted to the bottom of the placement frame 201, and a handle 5 for facilitating the movement of the insulation tester body 1 is bolted to the side wall of the placement frame 201. There are four universal wheels 4 which are respectively located at the four corners of the bottom of the placement frame 201. When in use, the insulation tester body 1 can be moved to a specified position more easily by means of the universal wheel 4 and the handle 5.
[0037] like Figure 5 As shown, a stabilizing rod 6 is bolted to the bottom of the placement frame 201, and one end of the stabilizing rod 6 is bolted to the side wall of the moving frame 202. When in use, the stabilizing rod 6 can improve the stability of the moving frame 202 and prevent the moving frame 202 from shaking due to extending a long distance to one side of the insulation tester body 1.
[0038] like Figure 6As shown, the two ends of the top of the moving block 205 are respectively bolted with a limit rod 7 and a limit plate 8 for limiting the rotating part 207. When the motor 208 drives the rotating part 207 to rotate, if the electric telescopic rod 211 needs to be placed vertically, the motor 208 drives the rotating part 207 to rotate until the rotating part 207 contacts the limit plate 8. At this time, the worker can stop the motor 208. If the electric telescopic rod 211 needs to be placed horizontally, the side wall of the rotating part 207 needs to contact the limit rod 7. By setting the limit rod 7 and the limit plate 8, the worker can more easily locate the rotation angle of the electric telescopic rod 211.
[0039] like Figure 1 As shown, a lighting lamp 9 is bolted to the side wall of the connecting plate 210. There are several lighting lamps 9 which are respectively located at the four corners of the connecting plate 210. When observing the inside of the dry-type air-core reactor through the camera 212, the lighting lamp 9 can increase the brightness of the inside of the dry-type air-core reactor, so that workers can see debris more easily.
[0040] like Figure 1 As shown, a taking slot 10 is provided on the top of the placement frame 201. There are two taking slots 10, which are respectively located on both sides of the insulation tester body 1. When in use, the insulation tester body 1 can be easily taken out from the inside of the placement frame 201 through the taking slots 10, which increases convenience.
[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
