Description

Technical Field

[0001] This utility model relates to the field of testing devices, specifically to an insulation performance testing device. Background Technology

[0002] Insulating wearable devices such as insulated hoods and boots require insulation performance testing before use or shipment to ensure their insulation performance meets standards. In related technologies, during the testing process, if the leakage current exceeds the limit—in other words, if the test current causes the insulating wearable device to break down—the test circuit needs to be manually disconnected. This results in low testing efficiency and low automation of the related technologies, making it impossible to test large quantities of insulating wearable devices. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an insulation performance testing device.

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following is for reference. Figure 1 This invention describes an insulation performance testing device according to an embodiment of the present invention.

[0024] like Figure 1 As shown, the insulation performance testing device of this utility model embodiment includes a water tank 1, a pressure supply component 2, and a test circuit 3.

[0025] Water tank 1 is used to hold insulating wearable devices.

[0026] Test circuit 3 consists of at least two circuits connected in parallel to the pressure supply assembly 2. Preferably, but not limited to, multiple circuits, such as 8, 16, etc.

[0027] The test circuit 3 includes a protective relay, a disconnecting circuit 32, and a connecting circuit 33 connected sequentially in the direction away from the pressure supply assembly 2. The protective relay has a movable connector 31 that can carry current. The disconnecting circuit 32 is connected between the movable connector 31 and the first end of the connecting circuit 33. The second end of the connecting circuit 33 is located in a conductive medium inside the insulating wearable device. The movable connector 31 is triggered and moved when the insulating wearable device is broken down, so that the disconnecting circuit 32 disconnects the connection between the movable connector 31 and the first end of the connecting circuit 33.

[0028] When using the insulation performance testing device, the insulating wearable equipment to be tested, such as insulating gloves and insulating boots, is placed in a water tank with a portion of the equipment submerged below the liquid surface, for example, two-thirds of the equipment. A conductive medium, such as water, metal particles, or metal balls, is placed inside the insulating wearable equipment. The insulating wearable equipment is aligned with the second terminal of the connecting circuit 33, and the second terminal of the connecting circuit 33 is inserted into the conductive medium inside the corresponding insulating wearable equipment. Then, the voltage supply component 2 is turned on, and current flows from the voltage supply component 2 to each test line 3 and is released through the second terminal of the connecting circuit 33. When the insulating wearable equipment is broken down, the corresponding protective relay is triggered, causing the moving connector 31 of the protective relay to move, thereby disconnecting the connecting connector 31 from the first terminal of the connecting circuit 33 by the corresponding disconnecting circuit 32. Other test lines 3 can continue to operate to test the corresponding insulating wearable equipment.

[0029] It should be noted that the water tank 1 is grounded. The water tank 1 can be made of metal and placed on the ground, or a grounding wire can be installed on the water tank 1. It is preferable to install a grounding wire.

[0030] The insulation performance testing device of this embodiment has at least two test lines connected in parallel to the voltage supply component. Each test line can test the corresponding insulated wearable device. In the test line, the movable joint of the protective relay is triggered and moves when the insulated wearable device is broken down, so that the disconnecting circuit automatically disconnects the connection between the movable joint and the first end of the connecting circuit, ensuring the safety of the testing device and allowing the remaining test lines to continue testing the corresponding insulated wearable devices. Therefore, the insulation performance testing device of this embodiment has a high degree of automation, high safety performance, high testing efficiency, and can test a large number of insulated wearable devices simultaneously.

[0031] In some embodiments, the disconnecting circuit 32 may break under tensile force.

[0032] like Figure 1 As shown, the movable connector 31 is positioned away from the connecting circuit 33 (e.g., Figure 1 The device moves (in the upward direction as shown) to apply a pulling force to the disconnecting circuit 32. The disconnecting circuit 32 breaks under this pulling force, thereby disconnecting the first end of the connection between the movable connector 31 and the connecting circuit 33 (as shown). Figure 1 The top of the connection circuit 33 is shown.

[0033] In some embodiments, the disconnect circuit 32 is detachably connected to the movable connector 31.

[0034] like Figure 1 As shown, the disconnecting circuit 32 can be sleeved on the movable connector 31, and the movable connector 31 extends along... Figure 1 The circuit moves in the forward and backward direction and disengages from the sleeve space of the disconnecting circuit 32, separating the disconnecting circuit 32 from the moving connector 31, and disconnecting the first end connecting the moving connector 31 and the connecting circuit 33 (e.g., Figure 1 The top of the connection circuit 33 is shown.

[0035] The disconnecting circuit 32 can also be attached to the movable connector 31 via a hinge, with the movable connector 31 positioned away from the connecting circuit 33 (e.g., ...). Figure 1 Move (in the upward direction as shown) to pull the slipknot loose, separating the disconnect circuit 32 from the movable connector 31, from the first end that disconnects the movable connector 31 and the connecting circuit 33 (as shown). Figure 1 The top of the connection circuit 33 is shown.

[0036] In some embodiments, the disconnecting circuit 32 and the first end of the connecting circuit 33 are detachably connected.

[0037] like Figure 1 As shown, the disconnecting circuit 32 is connected to the first end of the connecting circuit 33 via a hinge (e.g., Figure 1 The top of the connecting circuit 33 (as shown), the movable connector 31 moves away from the connecting circuit 33 (e.g., the top of the connecting circuit 33). Figure 1 Move the movable joint 31 (in the upward direction as shown) to pull the slip knot loose, separating the disconnect circuit 32 from the first end of the connecting circuit 33, and disconnect the movable joint 31 from the first end of the connecting circuit 33 (as shown). Figure 1 The top of the connection circuit 33 is shown.

[0038] In some embodiments, the insulation performance testing device of this utility model further includes an insulation support 4, which is disposed on the water tank 1, and the test line 3 is disposed on the insulation support 4.

[0039] like Figure 1 As shown, the insulating support 4 is mounted on the water tank 1, and the test circuit 3 is mounted on the insulating support 4. The insulating support 4 separates the pressure supply component 2 and the test circuit 3 from the water tank 1 to prevent the large voltage carried by the pressure supply component 2 and the test circuit 3 from being conducted to the water tank 1, thereby ensuring the safety of the operator and giving the insulation performance testing device strong safety performance.

[0040] In some embodiments, the insulation performance testing device of this utility model further includes a energized fixed connector 5, which is disposed on the insulating support 4. There are at least two fixed connectors 5 corresponding to the test line 3. The connecting circuit 33 and the protective relay are both disposed on the insulating support 4. The first end of the connecting circuit 33 is connected to the corresponding fixed connector 5. The disconnecting circuit 32 is connected between the corresponding movable connector 31 and the corresponding fixed connector 5, so that the disconnecting circuit 32 is connected to the first end of the corresponding connecting circuit 33 through the corresponding fixed connector 5.

[0041] like Figure 1 As shown, the insulating bracket 4 has a joint beam 411 and a load-bearing beam 412 extending in the left-right direction. The joint beam 411 and the load-bearing beam 412 are arranged at intervals in the vertical direction, and the joint beam 411 is located above the load-bearing beam 412.

[0042] The connector beam 411 is provided with a energized fixed connector 5. There are at least two fixed connectors 5 corresponding to the test line 3, preferably but not limited to multiple connectors, such as 8 or 16 connectors.

[0043] The protective relay is located on top of the insulating bracket 4 so that the movable joint 31 is positioned above the joint beam 411 and the fixed joint 5.

[0044] The middle part of the connecting circuit 33 is located on the supporting crossbeam 412, preferably passing through the supporting crossbeam 412. The top end of the connecting circuit 33 is connected to the corresponding fixed connector 5, and the bottom end of the connecting circuit 33 extends downward from the supporting crossbeam 412.

[0045] The disconnecting circuit 32 is connected between the corresponding movable connector 31 and the corresponding fixed connector 5, so as to indirectly connect the corresponding connecting circuit 33 through the fixed connector 5.

[0046] This facilitates the disconnection circuit 32 driven by the movable connector 31 to disconnect the movable connector 31 and the connection circuit 33.

[0047] It should be noted that if the top ends of the disconnecting circuit 32 and the connecting circuit 33 are detachably connected, the disconnecting circuit 32 can be tied to the fixed connector 5 by a slip knot, and the movable connector 31 can be moved upward to pull the slip knot loose, so that the disconnecting circuit 32 is separated from the fixed connector 5, thereby separating the disconnecting circuit 32 from the top end of the connecting circuit 33.

[0048] In some embodiments, the second end of the connecting circuit 33 (such as...) Figure 1 The bottom end of the connecting circuit 33 shown is spiral-shaped. This allows the length of the second end of the connecting circuit 33 to be extendable, facilitating the insertion of the second end of the connecting circuit 33 into the conductive medium inside the insulating wearable device, and the removal of the second end of the connecting circuit 33 from the insulating wearable device after testing is completed.

[0049] The connecting circuit 33 is preferably, but not limited to, a copper wire with an insulating layer, so as to facilitate stretching of the bottom end of the connecting circuit 33.

[0050] In some embodiments, the insulation performance testing device of this utility model further includes a control box 6, which is located on top of the insulation support 4, a protective relay is located inside the control box 6, and a movable joint 31 extends out from the box wall of the control box 6.

[0051] like Figure 1 As shown, a control box 6 is provided on the top of the insulating bracket 4. All the protective relays are located inside the control box 6, and the movable joint 31 of each protective relay extends out from the box wall of the control box 6.

[0052] The control box 6 serves to protect the protective relays and the operator, preventing accidental contact with the protective relays and avoiding issues such as the relays being triggered by external force or operator contact problems. The movable connector 31 extends from the wall of the control box 6 to facilitate connection to the disconnect circuit 32.

[0053] In some embodiments, the insulation performance testing device of this utility model further includes a display screen 7, which is disposed in the control box 6. There are at least two display screens 7 connected to the test line 3, and the display screens 7 are connected upstream of the corresponding protective relay. The display screens 7 are used to display the current value of the corresponding test line 3 when the corresponding insulating wearable device is broken down.

[0054] like Figure 1As shown, the control box 6 is equipped with a display screen 7. There are at least two display screens 7 corresponding to the test circuit 3, preferably but not limited to multiple, such as 8 or 16. The display screen 7 is connected to the corresponding test circuit 3 by wires and is connected upstream of the corresponding protective relay along the current direction in the test circuit 3. In other words, it is connected to the side of the corresponding protective relay away from the disconnecting circuit 32.

[0055] The display screen 7 is used to display the current value of the corresponding test line 3 when the corresponding insulated wearable device is broken down. In other words, the display screen 7 is used to display the current value of the connected test line 3 when the corresponding insulated wearable device is broken down. This is then recorded as a test result.

[0056] Furthermore, the display screen 7 can also display the real-time current value of the connected test circuit 3 when the corresponding insulated wearable device has not been broken down.

[0057] In some embodiments, the water tank 1 includes a tank body 11, a first insulating terminal 12 and a second insulating terminal 13. The first insulating terminal 12 is disposed at the first end of the tank body 11, the second insulating terminal 13 is disposed at the second end of the tank body 11, and the insulating bracket 4 is disposed on the first insulating terminal 12 and the second insulating terminal 13.

[0058] like Figure 1 As shown, the water tank 1 includes a tank body 11, a first insulating terminal 12 and a second insulating terminal 13. The first insulating terminal 12 is provided at the left end of the tank body 11, and the second insulating terminal 13 is provided at the right end of the tank body 11. An insulating bracket 4 is provided on the first insulating terminal 12 and the second insulating terminal 13, preferably but not limited to a load-bearing crossbeam 412 provided on the first insulating terminal 12 and the second insulating terminal 13.

[0059] More preferably, the supporting crossbeam 412, the first insulating terminal 12 and the second insulating terminal 13 are both arranged in two along the front-rear direction. The front supporting crossbeam 412 is arranged on the front first insulating terminal 12 and the front second insulating terminal 13, and the rear supporting crossbeam 412 is arranged on the rear first insulating terminal 12 and the rear second insulating terminal 13 to ensure the stable connection of the insulating bracket 4.

[0060] In some embodiments, both the first insulating terminal 12 and the second insulating terminal 13 are detachably connected to the insulating support 4.

[0061] like Figure 1 As shown, the load-bearing crossbeam 412 is detachably connected to both the first insulating terminal 12 and the second insulating terminal 13.

[0062] Before the insulation performance testing device performs the test, the supporting beam 412 is placed on the first insulating terminal 12 and the second insulating terminal 13 to install the insulating bracket 4 in place. After the insulation performance testing device completes the test, the supporting beam 412 is removed from the first insulating terminal 12 and the second insulating terminal 13 to remove the insulating bracket 4. This facilitates the placement of the insulation performance testing device.

[0063] In some embodiments, the insulating support 4 includes a support body 41, a first splicing member 42, and a second splicing member 43. The first splicing member 42 is detachably connected to a first end of the support body 41, and the second splicing member 43 is detachably connected to a second end of the support body 41. The insulating support 4 has a first position and a second position relative to the water tank 1. In the first position, the support body 41 is connected to the first splicing member 42 and the second splicing member 43. The first splicing member 42 is supported on a first insulating terminal 12, and the second splicing member 43 is supported on a second insulating terminal 13. In the second position, the first splicing member 42 is detached from both the first insulating terminal 12 and the support body 41, and the second splicing member 43 is detached from both the second insulating terminal 13 and the support body 41. The support body 41 is supported on the housing 11.

[0064] like Figure 1 As shown, the insulating bracket 4 includes a bracket body 41, a first splicing component 42, and a second splicing component 43. The bracket body 41 includes a joint beam 411 and a bearing beam 412. The left end of the bearing beam 412 is detachably connected to the first splicing component 42, and the right end of the bearing beam 412 is detachably connected to the second splicing component 43.

[0065] Before the insulation performance testing device performs the test, the first splice 42 and the second splice 43 are placed on the supporting beam 412. Then, the first splice 42 is placed on the first insulating terminal 12, and the second splice 43 is placed on the second insulating terminal 13, so that the supporting beam 412 is indirectly connected to the first insulating terminal 12 and the second insulating terminal 13, thereby placing the insulating bracket 4 in the first position supported by the first insulating terminal 12 and the second insulating terminal 13. At this time, the insulating wearable device can be tested.

[0066] After the insulation performance testing device completes the test, the first splice 42 and the second splice 43 are separated from the supporting beam 412. The supporting beam 412 is removed from the first insulating terminal 12 and the second insulating terminal 13. The supporting beam 412 is preferably, but not limited to, located between the first insulating terminal 12 and the second insulating terminal 13. The bracket body 41 is placed on the housing 11. The removed first splice 42 and the second splice 43 can be placed on the housing 11 or on the control box 6. This places the insulation bracket 4 in a second position on the housing 11. At this position, the insulation performance testing device has the same horizontal area and a smaller height than when the test was performed, thus requiring less space and facilitating placement of the insulation performance testing device.

[0067] It is understood that the load-bearing beam is not limited to being detachably connected to both the first and second splicing components. In other embodiments, the load-bearing beam is configured to be telescopic, extending to be supported on the first and second insulating terminals, and shortening to be positioned between the first and second insulating terminals, thereby allowing the support body to be placed on the housing.

[0068] In some embodiments, the water tank 1 includes a tank body 11 and a spreader 14. The spreader 14 is disposed inside the tank body 11. The insulating wearable device includes insulating gloves and insulating boots. The tank body 11 is used to support the insulating boots, and the spreader 14 is used to set the insulating gloves and spread them open.

[0069] like Figure 1 As shown, the box 11 is provided with a support 14 inside, which is preferably, but not limited to, a cylinder made of metal.

[0070] The insulating wearable equipment includes insulating gloves and insulating boots. When using the insulation performance testing device, the insulating gloves are inserted into the cylinder through the opening at the top, with the open end of the gloves fitted over the top of the cylinder to expand the gloves. Then, conductive media such as water, metal particles, or metal balls are placed inside the insulating gloves, and the corresponding connection circuit 33 is inserted. The insulating boots are placed on the bottom surface inside the housing 11, and then conductive media such as water, metal particles, or metal balls are placed inside the insulating boots, and the corresponding connection circuit 33 is inserted.

[0071] Preferably, the test lines 3 are arranged in at least two rows spaced apart in the front-to-back direction, more preferably two rows. Each row of test lines 3 includes multiple test lines 3 spaced apart in the left-to-right direction. The joint beam 411 and the load-bearing beam 412 are both arranged in two rows spaced apart in the front-to-back direction, corresponding to the test lines 3. A corresponding spreader 14 is provided below each of the front row of test lines 3 so that the front row of test lines 3 is used to test insulating gloves. No spreader 14 is provided below each of the rear row of test lines 3 so that the rear row of test lines 3 is used to test insulating boots. This allows the insulation performance testing device to test multiple insulating gloves and multiple insulating boots simultaneously.

[0072] Understandably, insulation performance testing equipment can also test only insulating boots or only insulating gloves.

[0073] In some embodiments, the water tank 1 includes a tank body 11, a plug (not shown in the figure) and a cover (not shown in the figure). The tank body 11 is provided with a drain outlet (not shown in the figure). The plug is used to plug the inner end of the drain outlet, and the cover is threadedly connected to the outer end of the drain outlet.

[0074] Specifically, the bottom of the housing 11 is provided with a drain outlet penetrating the wall of the housing 11. The inner end of the drain outlet is located on the inner wall of the housing 11. A plug is detachably sealed to the inner end of the drain outlet. The outer end of the drain outlet preferably, but not limited to, protrudes from the outer wall of the housing 11 and is provided with external threads. The cover is provided with internal threads adapted to the external threads so that the cover and the outer end of the drain outlet are threadedly connected. Thus, the plug and the cover cooperate to ensure that the drain outlet is sealed, preventing water leakage from the drain outlet during testing from affecting the test results.

[0075] Furthermore, the enclosure 11 is made of metal, and the weld seams of the enclosure 11 are coated with a waterproof layer to prevent water leakage from the weld seams from affecting the test results.

[0076] In some embodiments, the pressure supply assembly 2 includes a withstand voltage tester 21 and a step-up transformer 22. The withstand voltage tester 21 is connected to the step-up transformer 22, and at least two test lines 3 are connected in parallel to the step-up transformer 22.

[0077] like Figure 1 As shown, the withstand voltage tester 21, the step-up transformer 22 and the control box 6 are electrically connected in sequence. At least two protection relays in the control box 6 are connected in parallel so that at least two test lines 3 are connected in parallel to the step-up transformer 22.

[0078] The withstand voltage tester 21 is used to input the test voltage value and test time, and can monitor the actual voltage value and time the test. After inputting the test voltage value and test time, the withstand voltage tester 21 sends a signal to the step-up transformer 22, so that the step-up transformer 22 outputs voltage to at least two parallel test lines 3. When the voltage rises to the test value, the withstand voltage tester 21 starts timing. After the voltage maintains the test value for the required test time, the test ends and the voltage drops. The next test is performed after the actual voltage value returns to zero. The test results of the corresponding insulation performance testing device are obtained through the display screen 7.
