Description

Technical Field

[0002] High-voltage motor insulation testing uses testing instruments to calculate experimental data to determine surface conductive contamination, partial discharge, localized damage, the state of air gaps within the insulation, and the amount of partial discharge. The testing equipment typically consists of a testing element and testing leads. The testing leads connect to the motor's insulation layer, and the testing element processes the signal data. A problem with conventional high-voltage motor insulation testing equipment is that high-voltage motors are generally large, requiring long testing leads, which can easily lead to wire tangling.

[0003] To address this, existing technology provides a high-voltage motor insulation testing device, in which the testing wire is wound around a rotating roller, and the extension and retraction of the testing wire are achieved by manually controlling the rotation of the roller, thereby adjusting the extendable length of the testing wire and avoiding tangling. However, the problem is that when the high-voltage motor insulation testing device is not in use, the testing wire and the connector used to connect to the high-voltage motor are directly exposed, making them susceptible to damage from external forces.

[0040] The testing device required for high-voltage motor insulation testing typically consists of a testing element and a testing wire. The testing wire connects to the motor's insulation layer, and the testing element processes the signal data. A problem with conventional high-voltage motor insulation testing devices is that high-voltage motors are generally large, requiring a long testing wire, which easily leads to wire tangling. To address this, existing technology provides a high-voltage motor insulation testing device where the testing wire is wound around a rotating roller. The extension and retraction of the testing wire are manually controlled by rotating the roller, thus adjusting the extendable length of the testing wire and preventing tangling. However, this method has a drawback: when the high-voltage motor insulation testing device is not in use, the testing wire and the connector used to connect to the high-voltage motor are directly exposed, making them susceptible to damage from external forces.

[0041] In response to this, this embodiment provides a testing device to solve the problem that in the prior art, when the high-voltage motor insulation testing device is not in use, the testing wires and the connectors used to connect the high-voltage motor are directly exposed to the outside and are easily damaged by external forces. It can be used in the field of high-voltage motor insulation testing technology.

[0042] Reference Figures 1-4 The detection device includes a housing 1, a detection element 2, and a connecting structure 3. The housing 1 has a receiving groove 11 and an opening 12 communicating with the receiving groove 11. The detection element 2 is disposed in the housing 1. The connecting structure 3 includes a wire harness 31 and a connector 32 electrically connected to the wire harness 31. The wire harness 31 is electrically connected to the detection element 2, and the connector 32 is used to electrically connect to the component under test, thereby electrically connecting the detection element 2 and the component under test. Related detections can be performed on the component under test through the detection element 2. In this embodiment, the detection device performs high-voltage motor insulation detection, and the component under test is a high-voltage motor. Therefore, the detection element 2 is specifically a detection device for high-voltage motor insulation detection. In other embodiments, it can be replaced with other types of detection devices, depending on the different detection types. Furthermore, the principle and process of high-voltage motor insulation detection are already relatively mature technologies, and will not be elaborated further.

[0043] Continue to refer to Figures 1-4 The connector 32 is placed in the storage slot 11 and can enter and exit the storage slot 11 through the opening 12. Therefore, when the wire harness 31 is too long, part of the wire harness 31 can be placed in the storage slot 11 to avoid excessive wire harness 31 being exposed and affecting the staff.

[0044] Continue to refer to Figures 1-4The detection device also includes a cover plate 4 and a cover plate drive 5. The cover plate 4 can move relative to the housing 1 to open or close the opening 12. The cover plate drive 5 is used to drive the cover plate 4 to move, so that when the detection device is not in use, the cover plate drive 5 drives the cover plate 4 to close the opening 12 to seal the storage slot 11, preventing the wire harness 31 and the connector 32 from being directly exposed to the outside, thus protecting the wire harness 31 and the connector 32. In addition, the cover plate 4 is driven by the cover plate drive 5, which does not require manual operation and is convenient to use.

[0045] Continue to refer to Figures 1-4 The cover plate 4 is slidably disposed on the inner wall of the outer casing 1, and the cover plate 4 is provided with a rack 41. The cover plate driving component 5 is a motor, and the output end is connected to a gear 51. The gear 51 meshes with the rack 41, so that the motor can drive the gear 51 to rotate, and then drive the cover plate 4 to move in a straight line through the gear 51-rack 41 structure. Optionally, multiple gears 51 and multiple racks 41 are provided, and multiple gears 51 mesh with multiple racks 41 in a one-to-one correspondence. Alternatively, there is a single rack 41, and the width of the rack 41 is relatively wide, so multiple gears 51 mesh with the rack 41 simultaneously.

[0046] As an alternative, the cover plate drive 5 can also be configured as a cylinder or hydraulic cylinder, and includes a fixed end fixedly disposed on the housing 1 and a telescopic end that can reciprocate and extend relative to the fixed end. The cover plate 4 is disposed on the telescopic end. With this configuration, the cover plate 4 can also be moved by the cover plate drive 5 to open or close the opening 12.

[0047] Optionally, the inner wall of the outer casing 1 is also provided with a slide rail 14, and the cover plate 4 is slidably disposed on the slide rail 14.

[0048] Optionally, a handle 15 is also provided on the top of the outer casing 1 for easy carrying by the user.

[0049] Continue to refer to Figures 1-4 The detection device also includes a wire feeding wheel 6 that can rotate relative to the housing 1. The wire harness 31 is wound around the wire feeding wheel 6, so that the wire harness 31 can be wound or released by rotating the wire feeding wheel 6, thereby adjusting the extendable length of the wire harness 31 and avoiding the wire harness 31 from getting tangled.

[0050] Continue to refer to Figures 1-4 The detection device also includes a wire feeding wheel drive 7 for driving the wire feeding wheel 6 to rotate relative to the housing 1. This allows the wire feeding wheel 6 to rotate relative to the housing 1 without manual hand-cranking, making it convenient to use. Specifically, the wire feeding wheel drive 7 is a motor, with its output end connected to the wire feeding wheel 6.

[0051] Continue to refer to Figures 1-4The connecting structure 3 also includes a connecting rod 33, a receiving wheel 34 rotatably mounted on the connecting rod 33, and a conductive plate 35 fixedly mounted on the outer wall of the pay-off reel 6. The connecting rod 33, the receiving wheel 34, and the conductive plate 35 are all made of conductive material. One end of the connecting rod 33 away from the receiving wheel 34 is fixedly mounted on the detection element 2 and electrically connected to it. The outer wall of the receiving wheel 34 rolls in contact with the conductive plate 35, so that both ends of the receiving wheel 34 are electrically connected to the conductive plate 35. The conductive plate 35 is electrically connected to the wire harness 31, thereby electrically connecting the detection element 2 and the wire harness 31 through the connecting rod 33, the receiving wheel 34, and the conductive plate 35. Furthermore, the rolling contact between the outer wall of the receiving wheel 34 and the conductive plate 35 ensures that the electrical connection between the outer wall of the receiving wheel 34 and the conductive plate 35 is maintained when the pay-off reel 6 and the conductive plate 35 rotate, resulting in low frictional resistance.

[0052] Continue to refer to Figures 1-4 The connecting rod 33 includes a first connecting rod 331 and a second connecting rod 332 that can reciprocate relative to the first connecting rod 331. The first connecting rod 331 and the second connecting rod 332 are electrically connected. The first connecting rod 331 is connected to the detection element 2, and the second connecting rod 332 is connected to the receiving wheel 34. An elastic element 36 is provided between the first connecting rod 331 and the second connecting rod 332 to provide an elastic force that moves the second connecting rod 332 so that the outer wall of the receiving wheel 34 is pressed against the conductive plate 35. This ensures that the outer wall of the receiving wheel 34 is always pressed against the conductive plate 35, so that the receiving wheel 34 can make stable contact with the conductive plate 35 and avoid interruption of electrical connection.

[0053] Continue to refer to Figures 1-4 Insulation testing of high-voltage motors usually requires two testing lines. Therefore, in this embodiment, there are two wire harnesses 31 and two connectors 32. Both wire harnesses 31 are electrically connected to the testing element 2, and both connectors 32 are used to connect to the element under test.

[0054] Optionally, there are also two of each of the connecting rod 33, the receiving wheel 34, the conductive plate 35, and the elastic element 36, and the two wire harnesses 31, the two connectors 32, the two connecting rods 33, the two receiving wheels 34, the two conductive plates 35, and the two elastic elements 36 are all provided in a one-to-one correspondence.

[0055] Continue to refer to Figures 1-4 An insulating plate 61 is provided on the outer wall of the wire feeding reel 6. Two wire bundles 31 are located on both sides of the insulating plate 61, so that the two wire bundles 31 are separated by the insulating plate 61 to avoid the two wire bundles 31 from contacting each other and causing a short circuit.

[0056] Continue to refer to Figures 1-4The outer casing 1 also has a receiving cavity 13, in which the detection element 2 is disposed. The receiving groove 11 is connected to the receiving cavity 13 only through a wire passage hole for the wire harness 31 to pass through, thereby separating the receiving groove 11 from the receiving cavity 13 and separating the connector 32 from the detection element 2 and other structures. Optionally, the cover plate drive 5, the wire feeding wheel 6, the wire feeding wheel drive 7, the connecting rod 33, the electric receiving wheel 34, the conductive plate 35, and the elastic element 36 are all disposed in the receiving cavity 13, and when the opening 12 is opened, the cover plate 4 is also located in the receiving cavity 13.

[0057] Continue to refer to Figures 1-4 The detection device also includes a display screen 8 disposed on the outer wall of the housing 1. The detection element 2 is communicatively connected to the display screen 8, so that the detection signal obtained by the detection element 2 can be transmitted to the display screen 8 for display, thereby providing the detection information to the staff.

[0058] Optionally, the detection element 2 is a controller, capable of acquiring detection signals through the connection structure 3 and processing the detection signals to convert them into electrical signals. Furthermore, the cover plate drive 5 and the wire feeding wheel drive 7 are both communicatively connected to the detection element 2, allowing the detection element 2 to control the cover plate drive 5 and the wire feeding wheel drive 7, thereby driving the cover plate 4 and the wire feeding wheel 6 to move. A button 81 is also provided on the outer wall of the housing 1, communicatively connected to the detection element 2, allowing the user to operate the detection device via the button 81.
