Description

Technical Field

[0001] This utility model relates to the field of high-voltage lines, and in particular to a detection device for high-voltage lines in new energy sources. Background Technology

[0002] In the high-voltage electrical systems of new energy vehicles (typically 300-800V), high-voltage lines are core components connecting the power battery pack, electric drive system, and high-voltage power distribution module. Their performance and reliability directly affect the safety of the entire vehicle. According to industry standards, high-voltage lines must undergo tests such as conductor resistance, insulation withstand voltage, and shielding continuity before leaving the factory. These tests typically require two types of testing instruments: a micro-resistance tester and a withstand voltage insulation tester. Therefore, the current testing process has a significant efficiency bottleneck: during testing, operators need to switch test fixtures multiple times for the same high-voltage line to connect it to the micro-resistance tester and the withstand voltage insulation tester respectively. This repeated disassembly and installation of different test fixtures significantly increases the testing time for a single product, thus affecting the testing efficiency of high-voltage lines.

[0003] Based on this, the present invention provides a testing device for high-voltage lines in new energy sources. Through the integrated testing device, the testing of high-voltage lines can be completed using a micro resistance tester and a withstand voltage insulation tester without the need for multiple switching of test fixtures, thereby improving the testing efficiency of high-voltage lines. Utility Model Content

[0004] Based on this, it is necessary to provide a testing device for high-voltage lines in new energy sources, including a housing, which includes a support frame and an outer shell covering the support frame; an industrial control computer and a micro-resistance tester and a withstand voltage insulation tester connected to the industrial control computer are installed inside the housing; the outer shell has windows on its control panel and display screen corresponding to the industrial control computer, the micro-resistance tester, and the withstand voltage insulation tester to expose them; it also includes a clamping module for fixing the high-voltage line, the clamping module having two terminal contacts and two shielding contacts, which are respectively used to contact and conduct electricity with two terminals and two shielding rings at both ends of the high-voltage line fixed on the clamping module; the housing also includes a converter module connected to the industrial control computer, the converter module being connected to the terminal contacts and the shielding contacts, which, under the control of the industrial control computer, connects some or all of the terminal contacts and the shielding contacts to the micro-resistance tester or the withstand voltage insulation tester.

[0005] In this invention, a clamping mold is used to fix the high-voltage wire to be tested. After the high-voltage wire is fixed on the clamping mold, its two terminals and two shielding rings at both ends will respectively abut against the two terminal contacts and two shielding contacts of the clamping mold, thereby achieving conductivity with the terminal contacts and shielding contacts. At this time, the terminals and shielding rings of the high-voltage wire will be connected to the adapter module. Under the control of an industrial control computer, the adapter module can connect part or all of the terminals and shielding rings that are connected to it to the micro resistance tester or the withstand voltage insulation tester according to different testing requirements. For example, the two terminals of the high-voltage wire can be connected to the positive and negative source lines of the micro resistance tester, respectively. Alternatively, a terminal block and a shielding ring located at the same end of the high-voltage line can be connected to the high-voltage output line and return line of the withstand voltage insulation tester, respectively. Or, the two shielding rings of the high-voltage line can be connected to the positive and negative source lines of the micro-resistance tester, respectively. By changing the connection lines through a conversion module, the high-voltage line can be tested using both a micro-resistance tester and a withstand voltage insulation tester without switching the test fixtures. For example, the internal resistance, insulation withstand voltage, and shielding continuity tests of the high-voltage line can be performed. Therefore, this invention eliminates the need to switch test fixtures when testing high-voltage lines, effectively improving testing efficiency.

[0006] Furthermore, the clamping module includes two fixing fixtures, each fixture comprising a horizontally arranged base plate and a vertically arranged vertical plate on the base plate. A long, strip-shaped pressure plate is vertically mounted on the vertical plate, and the pressure plate is horizontally positioned. The base plate has a first mounting seat and a second mounting seat, located below both ends of the pressure plate. The top of the first mounting seat has a first receiving groove for accommodating the terminal of a high-voltage wire, and the first receiving groove extends through the first mounting seat along the length of the pressure plate. The top of the second mounting seat has a second receiving groove for accommodating the shielding ring of a high-voltage wire, and the second receiving groove extends through the second mounting seat along the length of the pressure plate. A conductive layer is laid on the inner wall of the first receiving groove to form a terminal contact, and a conductive layer is laid on the inner wall of the second receiving groove to form a shielding contact.

[0007] In this invention, the shape of the first receiving groove needs to be set according to the size of the high-voltage line terminal so that the terminal can be locked in the first receiving groove. Similarly, the shape of the second receiving groove needs to be set according to the size of the high-voltage line shielding ring so that the shielding ring can be locked in the second receiving groove. The pressure plate can be pressed against the high-voltage line by lowering, thereby ensuring that the high-voltage line terminal and the shielding layer can abut and conduct the terminal contact and the shielding contact while fixing the high-voltage line.

[0008] Furthermore, the lower surface of the pressure plate is provided with a first protrusion and a second protrusion corresponding to the first receiving groove and the second receiving groove, respectively, and the first protrusion and the second protrusion are located directly above the first receiving groove and the second receiving groove, respectively.

[0009] In this invention, the first protrusion and the second protrusion are set on the lower surface of the pressure plate. Their height needs to be set according to the size of the high-voltage line terminal and the shielding ring to ensure that the first protrusion and the second protrusion simultaneously abut against the terminal and the shielding ring under the action of the pressure plate, thereby ensuring that the high-voltage line terminal and the shielding ring can be fixed at the same time.

[0010] Furthermore, the pressure plate is vertically mounted on the vertical plate via a first cylinder installed on the vertical plate, and a reversing valve for controlling the first cylinder is also provided on the vertical plate corresponding to the first cylinder.

[0011] In this invention, the pressure plate is driven by a first cylinder mounted on a vertical plate. The action of the first cylinder can be controlled by a reversing valve, thereby enabling the pressure plate to press and release the high-voltage line.

[0012] Furthermore, the housing has through holes, and the terminal contacts on the clamping module and the shielding contacts are connected to the adapter module through wires passing through the through holes.

[0013] In this invention, the terminal contacts and shielding contacts on the clamping module located on the outside of the housing are connected to the adapter module inside the housing via wires passing through the housing.

[0014] Furthermore, the adapter module includes several adapters, each adapter including a mounting plate mounted on the housing, and a first mounting strip and a second mounting strip arranged vertically on the mounting plate. The second mounting strip is fixedly mounted on the mounting plate and is movably mounted on the mounting plate. The first mounting strip also has several vertically penetrating first insertion holes, and the second mounting strip has several corresponding second insertion holes. The second insertion holes are vertically penetrating the second mounting strip and located directly below the corresponding first insertion hole. A first conductive rod is inserted into each of the first insertion holes. A second conductive rod is inserted into the second socket. The first conductive rod can be connected to the second conductive rod below it by moving the first mounting strip downwards. The terminal contact and the shielding contact are connected to the adapter module by connecting the first conductive rod with a wire. The second conductive rod is connected to the test lines of the micro resistance tester and the withstand voltage insulation tester by a wire. The adapter module connects some or all of the terminal contact and the shielding contact to the micro resistance tester or the withstand voltage insulation tester by raising and lowering the first mounting strip of its adapter.

[0015] In this invention, the adapter module comprises multiple adapters. The adapters, through the raising and lowering of the first mounting strip, achieve the contact and separation of the first conductive rod on the first mounting strip and the second conductive rod on the second mounting strip, thereby enabling the conduction and disconnection of the first and second conductive rods. The first conductive rod is used to connect with the terminal contacts and the shielding contacts, while the second conductive rod is used to connect with the test leads of the micro-resistance tester and the withstand voltage insulation tester. Therefore, the adapter can achieve the connection and separation of the terminal contacts and the shielding contacts with the micro-resistance tester or the withstand voltage insulation tester through the raising and lowering of the first mounting strip, thus enabling the adapter module to connect some or all of the terminal contacts and the shielding contacts to the micro-resistance tester or the withstand voltage insulation tester. The operation of the adapter is controlled by an industrial control computer to ensure accurate cooperation with the micro-resistance tester and the withstand voltage insulation tester to complete the tests.

[0016] In this invention, depending on the different testing items, the test lines of the micro resistance tester and the withstand voltage insulation tester can be connected to different second conductive bars of different adapters, and the terminal contacts and shielding contacts can be connected to the corresponding first conductive bars of the corresponding adapters, so as to complete all testing items without switching the test fixtures on the high voltage line.

[0017] For example, three adapters are used to connect the terminal contacts and shielded contacts to the microresistance tester and the withstand voltage insulation tester. Specifically, the three adapters are adapter number one, adapter number two, and adapter number three. The positive and negative source lines of the microresistance tester are respectively connected to the two second conducting rods of adapter number one, and the two terminal contacts are respectively connected to the first conducting rod above the second conducting rod connected to the microresistance tester in adapter number one. The positive and negative source lines of the microresistance tester are also respectively connected to the two second conducting rods of adapter number two, and the two shielded contacts are respectively connected to the first conducting rod above the second conducting rod connected to the microresistance tester in adapter number two. The high-voltage output line and return line of the withstand voltage insulation tester are respectively connected to the two second conducting rods of adapter number three, and are located at the same end as the high-voltage line. One terminal contact and one shielding contact, which are connected to the terminal block and shielding ring, are respectively connected to the first conducting rod above the second conducting rod of the third adapter, which is connected to the withstand voltage insulation tester. At this time, the first and second conducting rods of the first adapter are connected, while the first and second conducting rods of the other two adapters are disconnected, allowing measurement of the internal resistance of the high-voltage line. Similarly, when the first and second conducting rods of the second adapter are connected, and the first and second conducting rods of the other two adapters are disconnected, the continuity of the high-voltage line shielding layer can be measured. When the first and second conducting rods of the third adapter are connected, and the first and second conducting rods of the other two adapters are disconnected, the withstand voltage insulation of the high-voltage line can be measured. When multiple first or second conducting rods need to be connected simultaneously to the terminal contact, shielding contact, and the test leads of the micro-resistance tester and withstand voltage insulation tester, this can be achieved by branching the corresponding wires.

[0018] Furthermore, the first mounting strip is vertically mounted on the mounting plate via a second cylinder mounted on the mounting plate, and the second cylinder is connected to the industrial control computer via a solenoid valve.

[0019] In this invention, the industrial control computer controls the action of the second cylinder through a solenoid valve, thereby controlling the conduction and separation of the first and second conductive rods in the adapter, so as to match it with the micro resistance tester and the withstand voltage insulation tester.

[0020] Furthermore, the upper edge, left edge and right edge of the mounting plate are all provided with retaining edges, which together form a retaining cover with a lower opening.

[0021] In this invention, the baffle at the edge of the mounting plate can provide a certain degree of protection for the conduction of the first and second conducting rods inside, thereby ensuring that the conduction of the first and second conducting rods that are in contact with each other can be smoothly achieved.

[0022] Furthermore, the mounting plate has several through holes on its upper edge.

[0023] In this invention, the through hole on the side of the mounting plate can be used for the passage of wires, thereby facilitating the connection of the terminal contacts and shielding contacts with the first conductive rod.

[0024] The principle and effects of this utility model will be further explained below with reference to the above technical solution and the accompanying drawings:

[0025] In this invention, the clamping mold is used to fix the high-voltage line to be tested. After the high-voltage line is fixed on the clamping mold, its two terminals and two shielding rings at both ends will abut against the two terminal contacts and two shielding contacts of the clamping mold, thereby achieving conduction with the terminal contacts and shielding contacts. At this time, the terminals and shielding rings of the high-voltage line will be connected to the adapter module. Under the control of the industrial control computer, the adapter module can connect part or all of the terminals and shielding rings that are connected to it to the micro resistance tester or the withstand voltage insulation tester according to different testing requirements. It can be seen that this invention can eliminate the need to switch test fixtures when testing high-voltage lines, and can effectively improve testing efficiency. Attached Figure Description

Detailed Implementation

[0032] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0033] like Figure 1-4 A testing device for high-voltage power lines in new energy applications includes a housing 1, which comprises a support frame and an outer shell covering the support frame. An industrial control computer 2 is housed within the housing 1, along with a micro-resistance tester 3 and a withstand voltage insulation tester 4 connected to the industrial control computer 2. The outer shell has windows on its control panel and display screen corresponding to the industrial control computer 2, the micro-resistance tester 3, and the withstand voltage insulation tester 4, allowing them to be exposed. The device also includes a clamping module for fixing the high-voltage power line. The clamping module has two terminal contacts 542 and two shielded contacts 552, which are respectively used to contact and conduct electricity with two terminals and two shielding rings at both ends of the high-voltage power line fixed on the clamping module. The housing 1 also includes a converter module connected to the industrial control computer 2. The converter module connects the terminal contacts 542 and the shielded contacts 552, and under the control of the industrial control computer 2, connects some or all of the terminal contacts 542 and the shielded contacts 552 to the micro-resistance tester 3 or the withstand voltage insulation tester 4.

[0034] In this invention, the clamping mold is used to fix the high-voltage wire to be tested. After the high-voltage wire is fixed on the clamping mold, its two terminals and two shielding rings at both ends will respectively abut against the two terminal contacts 542 and the two shielding contacts 552 of the clamping mold, thereby achieving conduction with the terminal contacts 542 and the shielding contacts 552. At this time, the terminals and shielding rings of the high-voltage wire will be connected to the adapter module. Under the control of the industrial control computer 2, the adapter module can connect part or all of the terminals and shielding rings connected to it to the micro resistance tester 3 or the withstand voltage insulation tester 4 according to different testing requirements. For example, the two terminals of the high-voltage wire can be connected to the source positive terminal of the micro resistance tester 3. The high-voltage line can be tested by connecting the positive and negative poles, or by connecting a terminal and a shielding ring at the same end of the high-voltage line to the high-voltage output line and return line of the withstand voltage insulation tester 4, respectively. Alternatively, the two shielding rings of the high-voltage line can be connected to the positive and negative poles of the source line of the micro resistance tester 3, respectively. By changing the connection lines through the conversion module, the high-voltage line can be tested using the micro resistance tester 3 and the withstand voltage insulation tester 4 without switching the test fixtures. For example, the internal resistance test, insulation withstand voltage test, and shielding layer connectivity test of the high-voltage line can be performed. It can be seen that this utility model can eliminate the need to switch test fixtures when testing high-voltage lines, which can effectively improve the testing efficiency.

[0035] In one embodiment, the clamping module includes two fixing fixtures 5. Each fixing fixture 5 includes a horizontally arranged base plate 51 and a vertically arranged vertical plate 52 on the base plate 51. A long strip-shaped pressure plate 53 is vertically and movably arranged on the vertical plate 52, and the pressure plate 53 is horizontally arranged. A first mounting seat 54 and a second mounting seat 55 are arranged on the base plate 51. The first mounting seat 54 and the second mounting seat 55 are respectively located below both ends of the pressure plate 53. The top end of the first mounting seat 54 has a first receiving groove for accommodating the terminal of the high-voltage line, and the first receiving groove extends through the first mounting seat 54 along the length direction of the pressure plate 53. The top end of the second mounting seat 55 has a second receiving groove 551 for accommodating the shielding ring of the high-voltage line, and the second receiving groove 551 extends through the second mounting seat 55 along the length direction of the pressure plate 53. The inner sidewall of the first receiving groove is covered with a conductive layer to form a terminal contact 542, and the inner sidewall of the second receiving groove 551 is covered with a conductive layer to form a shielding contact 552.

[0036] In this embodiment, the shape of the first receiving groove needs to be set according to the size of the high-voltage line terminal so that the terminal can be locked in the first receiving groove. Similarly, the shape of the second receiving groove 551 needs to be set according to the size of the high-voltage line shielding ring so that the shielding ring can be locked in the second receiving groove 551. The pressure plate 53 can be pressed against the high-voltage line by descending, so as to ensure that the high-voltage line terminal and the shielding layer can abut and conduct the terminal contact 542 and the shielding contact 552 while fixing the high-voltage line.

[0037] In one embodiment, the lower surface of the pressure plate 53 is provided with a first protrusion and a second protrusion 532 corresponding to the first receiving groove and the second receiving groove 551, respectively, and the first protrusion and the second protrusion 532 are located directly above the first receiving groove and the second receiving groove 551, respectively.

[0038] In this embodiment, the first protrusion and the second protrusion 532 are set to protrude from the lower surface of the pressure plate 53. Their height needs to be set according to the size of the high-voltage line terminal and the shielding ring to ensure that the first protrusion and the second protrusion 532 are simultaneously pressed against the terminal and the shielding ring under the drive of the pressure plate 53, thereby ensuring that the high-voltage line terminal and the shielding ring can be fixed at the same time.

[0039] In one embodiment, the pressure plate 53 is vertically mounted on the vertical plate 52 via a first cylinder 56 installed on the vertical plate 52, and the vertical plate 52 is also provided with a reversing valve 57 for controlling the first cylinder 56.

[0040] In this embodiment, the pressure plate 53 is driven by the first cylinder 56 installed on the vertical plate 52. The action of the first cylinder 56 can be controlled by the reversing valve 57, thereby realizing the pressing and releasing of the high-voltage line by the pressure plate 53.

[0041] In one embodiment, the housing has a through hole, and the terminal contact 542 and the shielding contact 552 on the clamping module are connected to the adapter module through a wire passing through the through hole.

[0042] In this embodiment, the terminal contact 542 and shielding contact 552 on the clamping module located outside the housing 1 are connected to the adapter module inside the housing 1 via wires passing through the housing.

[0043] In one embodiment, the adapter module includes a plurality of adapters. Each adapter includes a mounting plate 61 mounted on the housing 1, and a first mounting strip 63 and a second mounting strip 64 arranged vertically on the mounting plate 61. The second mounting strip 64 is fixedly mounted on the mounting plate 61 and is movably mounted on the mounting plate 61. The first mounting strip 63 has a plurality of vertically penetrating first insertion holes 631. The second mounting strip 64 has a plurality of corresponding second insertion holes 641, which vertically penetrate the second mounting strip 64 and are located directly below the corresponding first insertion hole 631. A first conductive rod 6 is inserted into each of the first insertion holes 631. 32. A second conductive rod 642 is inserted into the second socket 641. The first conductive rod 632 can abut against the second conductive rod 642 below it by moving the first mounting strip 63 downward, thereby making contact with the second conductive rod 642 below it. The terminal contact 542 and the shielding contact 552 are connected to the adapter module by connecting the first conductive rod 632 with a wire. The second conductive rod 642 is connected to the test lines of the micro resistance tester 3 and the withstand voltage insulation tester 4 by a wire. The adapter module connects part or all of the terminal contact 542 and the shielding contact 552 to the micro resistance tester 3 or the withstand voltage insulation tester 4 by raising and lowering the first mounting strip 63 of its adapter.

[0044] In this embodiment, the adapter module consists of multiple adapters. The adapters, through the raising and lowering of the first mounting strip 63, enable the first conductive rod 632 on the first mounting strip 63 to abut and separate from the second conductive rod 642 on the second mounting strip 64, thereby enabling the first conductive rod 632 and the second conductive rod 642 to conduct and disconnect. The first conductive rod 632 is used to connect with the terminal contact 542 and the shielding contact 552, and the second conductive rod 642 is used to connect with the test leads of the micro resistance tester 3 and the withstand voltage insulation tester 4. Therefore, the adapter can achieve the connection and separation of the terminal contact 542 and the shielding contact 552 with the micro resistance tester 3 or the withstand voltage insulation tester 4 through the raising and lowering of the first mounting strip 63, thereby enabling the adapter module to connect part or all of the terminal contact 542 and the shielding contact 552 to the micro resistance tester 3 or the withstand voltage insulation tester 4. The adapter's operation is controlled by the industrial control computer 2, enabling it to accurately cooperate with the micro resistance tester 3 and the withstand voltage insulation tester 4 to complete the test.

[0045] In this embodiment, depending on the different test items, the test lines of the micro resistance tester 3 and the withstand voltage insulation tester 4 can be connected to different second conductive rods 642 of different adapters, and the terminal contacts 542 and shielding contacts 552 can be connected to the corresponding first conductive rods 632 of the corresponding adapters, so as to complete all test items without switching the test fixtures on the high voltage line.

[0046] For example, the terminal contact 542 and the shielded contact 552 are connected to the micro resistance tester 3 and the withstand voltage insulation tester 4 via three adapters. Specifically, the three adapters are adapter 1, adapter 2, and adapter 3. The positive and negative source lines of the micro-resistance tester 3 are connected to the two second conducting rods 642 of adapter 1, and the two terminal contacts 542 are connected to the first conducting rod 632 above the second conducting rod 642 connected to the micro-resistance tester 3 in adapter 1. The positive and negative source lines of the micro-resistance tester 3 are also connected to the two second conducting rods 642 of adapter 2, and the two shielded contacts 552 are connected to the first conducting rod 632 above the second conducting rod 642 connected to the micro-resistance tester 3 in adapter 2. The high-voltage output line and return line of the withstand voltage insulation tester 4 are connected to the two second conducting rods 642 of adapter 3, and the terminal block and shielding ring located at the same end of the high-voltage line are connected to the same terminal block and shielding ring. One terminal contact 542 and one shielding contact 552 are respectively connected to the first conducting rod 632 above the second conducting rod 642 connected to the withstand voltage insulation tester 4 in adapter No. 3. At this time, the first conducting rod 632 and the second conducting rod 642 of adapter No. 1 are conducting, while the first conducting rod 632 and the second conducting rod 642 of the other two adapters are disconnected, so the internal resistance of the high voltage line can be measured. The first conducting rod 632 and the second conducting rod 642 of adapter No. 2 are conducting, while the first conducting rod 632 and the second conducting rod 642 of the other two adapters are disconnected, so the continuity of the shielding layer of the high voltage line can be measured. The first conducting rod 632 and the second conducting rod 642 of adapter No. 3 are conducting, while the first conducting rod 632 and the second conducting rod 642 of the other two adapters are disconnected, so the withstand voltage insulation of the high voltage line can be measured. When the terminal contact 542 and shield contact 552, as well as the detection lines of the micro resistance tester 3 and withstand voltage insulation tester 4, need to be connected to multiple first conductive rods 632 or second conductive rods 642 at the same time, they can be used by splitting the corresponding wires.

[0047] In one embodiment, the first mounting strip 63 is vertically mounted on the mounting plate 61 via a second cylinder mounted on the mounting plate 61, and the second cylinder is connected to the industrial control computer 2 via a solenoid valve.

[0048] In this embodiment, the industrial control computer 2 controls the action of the second cylinder through the solenoid valve, thereby controlling the conduction and separation of the first conductive rod 632 and the second conductive rod 642 in the adapter, so that it matches the micro resistance tester 3 and the withstand voltage insulation tester 4.

[0049] In one embodiment, the upper edge, left edge and right edge of the mounting plate 61 are provided with baffles, which together form a cover 62 with an opening at the lower end.

[0050] In this embodiment, the baffle 62 at the edge of the mounting plate 61 can provide a certain degree of protection for the conduction of the first conductive rod 632 and the second conductive rod 642 inside, thereby ensuring that the conduction of the first conductive rod 632 and the second conductive rod 642 that are in contact with each other can be smoothly achieved.

[0051] In one embodiment, the mounting plate 61 has several through holes on the upper edge of the flange.

[0052] In this embodiment, the through hole on the upper side of the mounting plate 61 can be used for the passage of wires, thereby facilitating the connection of the terminal contact 542 and the shielding contact 552 with the first conductive rod 632.

[0053] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
