[0038] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0039] like Figure 1As shown, according to an embodiment of the present application, a motor stator insulation measurement termination device is proposed, including: a housing 11, two terminals 12 and a conductive piece 13; a first terminal 121 is arranged on a first side of the housing 11, and the first terminal 121 is used to install a first cable 14; a second terminal 122 is arranged on a second side of the housing 11, and the second terminal 122 is used to install a second cable 15; a first end of the conductive piece 13 is detachably connected to the first cable 14, and a second end of the conductive piece 13 is detachably connected to the second cable 15, and the first cable 14 and the second cable 15 are conductively connected through the conductive piece 13.

[0040] The motor stator insulation measurement termination device provided in the embodiment of the present application includes a housing 11, two terminal blocks 12 and a conducting member 13; a first cable 14 is connected and conducted with a corresponding second cable 15 through the conducting member 13. When the first cable 14 and the second cable 15 need to be disconnected for the high-voltage motor stator insulation measurement, the first cable 14 and the second cable 15 can be disconnected by disassembling and removing the conducting member 13. The first cable 14 and the second cable 15 can be quickly isolated without removing the cable itself, thus avoiding cumbersome cable disassembly and assembly operations, saving time and effort; when the high-voltage motor stator insulation measurement is completed and the first cable 14 and the second cable 15 need to be reconnected, the two ends of the conducting member 13 are respectively connected to the first cable 14 and the corresponding second cable 15, so that the first cable 14 and the corresponding second cable 15 can be conducted, thus realizing the first cable The electrical connection between the first cable 14 and the second cable 15 is simple and efficient to operate; there is no need to move or bend the first cable 14 and the second cable 15 during the process of disconnecting and connecting the cables, so as to avoid insulation damage caused by the cable being completely connected and protect the insulation layer of the cables from being damaged; the first cable 14 and the second cable 15 are fixed by the shell 11, which plays a protective role for the first cable 14 and the second cable 15, further preventing the first cable 14 and the second cable 15 from being frequently bent during the disassembly and assembly process, reducing the mechanical stress generated during the disassembly and assembly of the cables, and preventing the insulation layer of the cables from being damaged. At the same time, the shell 11 provides an independent operating space for the first cable 14 and the second cable 15, reducing the difficulty of disassembly and assembly of the first cable 14 and the second cable 15, and further improving the disassembly and assembly efficiency of the first cable 14 and the second cable 15, which is beneficial to improving the stator insulation measurement efficiency of the high-voltage motor.

[0041] Furthermore, the number of first cables 14 is equal to the number of second cables 15, which is equal to the number of conductive parts 13. Each first cable 14 corresponds to a second cable 15. Only one first cable 14 and one second cable 15 are connected to each conductive part 13. The corresponding first cables 14 and second cables 15 are connected through the conductive part 13, that is, a first cable 14, a second cable 15 and a conductive part 13 constitute a cable group, so that each cable group is separately conductive, which is conducive to ensuring electrical isolation and structural stability between the cable groups.

[0042] Furthermore, the conducting member 13 may be made of a material with good conductivity, such as copper or aluminum, to ensure the performance of the conducting member 13 under high current intensity.

[0043] like Figure 1 As shown, in a feasible embodiment, the first cable 14 passes through the first terminal 121 and extends into the housing 11, the second cable 15 passes through the second terminal 122 and extends into the housing 11, and the conductive member 13 connects the first cable 14 and the second cable 15 in the housing 11.

[0044] In this technical solution, one end of the first cable 14 and the second cable 15 that are connected to each other extends into the housing 11, and the conductive member 13 connects the first cable 14 and the second cable 15 while restricting the first cable 14 and the second cable 15 inside the housing 11, so that the housing 11 can be used to protect the one end of the first cable 14 and the second cable 15 that are connected to each other, so that the electrical connection between the first cable 14 and the second cable 15 is stable and reliable, which is conducive to improving the safety of the motor operation.

[0045] In a feasible implementation manner, one of the first cable 14 and the second cable 15 is a power supply cable, and the other of the first cable 14 and the second cable 15 is a power consumption cable.

[0046] In this technical solution, the power supply cable of the high-voltage motor stator is large in size and hardness, that is, the first cable 14 and the second cable 15 are hard and not easy to bend. The first cable 14 and the second cable 15 are electrically connected through the conductive piece 13. When measuring the insulation of the high-voltage motor stator, it is only necessary to remove the conductive piece 13 without removing the cable itself, so as to achieve rapid isolation of the motor stator, so as to ensure the accuracy of the insulation measurement result and the safety of operation, and reduce the labor intensity; the power supply cable and the power supply cable are connected through the conductive piece 13, and the shell 11 is provided to protect the power supply cable, the power supply cable and the conductive piece 13, so as to provide an independent operating space for the power cable and the power cable, reduce the difficulty of disassembly and assembly between the power cable and the power cable, and effectively reduce the mechanical stress on the power supply cable and the power cable during the disassembly and assembly process, protect the insulation layer, and extend the service life of the power supply cable and the power cable.

[0047] like Figure 3 As shown, in a feasible implementation manner, the first wiring terminal 121 and the second wiring terminal 122 are respectively disposed on two opposite side walls of the housing 11 .

[0048] In this technical solution, the first terminal 121 and the second terminal 122 are respectively arranged on two opposite side walls of the outer shell 11, so that the first cable 14 and the second cable 15 extend into the outer shell 11 from two opposite side walls of the outer shell 11 respectively, preventing the first cable 14 and the second cable 15 from bending during the assembly process with the outer shell 11, helping to maintain the straightness of the first cable 14 and the second cable 15 after conduction, so as to reduce the possibility of bending during the assembly process of the cable and the termination device, and prevent insulation damage of the cable during the assembly process with the termination device.

[0049] like Figure 1 and Figure 2 As shown, in a feasible implementation, the motor stator insulation measurement termination device also includes: an insulating support 16, the insulating support 16 is arranged in the housing 11, the insulating support 16 is located below the cable, the insulating support 16 corresponds to the cable one by one, and the insulating support 16 supports the cable.

[0050] In this technical solution, an insulating support 16 is arranged inside the housing 11, and the insulating support 16 corresponds to the cable one by one. The first cable 14 and the second cable 15 are installed on the insulating support 16. On the one hand, the insulating support 16 supports the corresponding first cable 14 or the second cable 15 to prevent the joint of the first cable 14 and the second cable 15 from sagging, so as to maintain the straightness of the first cable 14 and the second cable 15 and prevent the insulation damage of the first cable 14 and the second cable 15 due to sagging; on the other hand, the insulating support 16 supports the first cable 14 and the second cable 15, which can ensure electrical isolation between the cables, thereby ensuring electrical isolation between the phases of the motor after the first cable 14 and the second cable 15 are turned on, and ensuring the safety of the motor operation.

[0051] In this technical solution, after the conductive member 13 is dismantled and removed, there is no need to remove the first cable 14 and the second cable 15 from the corresponding insulating support member 16 to maintain the supporting state of the insulating support member 16 on the cables to prevent the cables from sagging, thereby preventing insulation damage caused by bending of the cables during the measurement process.

[0052] It can be understood that each insulating support member 16 supports one first cable 14 or one second cable 15 , that is, each insulating support member 16 supports only one cable.

[0053] Furthermore, the motor is a three-phase motor, and six insulating supports 16 are provided inside the housing 11. The six insulating supports 16 are respectively used to fix three power supply cables and three power cables of the motor to ensure electrical isolation between the phases of the motor.

[0054] Furthermore, the insulating support member 16 may be an insulator, or may be made of other high-strength insulating materials.

[0055] Specifically, a protective layer is coated on the insulator to enhance the voltage resistance of the insulating support 16 and ensure the reliability of electrical isolation between the phases of the motor.

[0056] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the insulating support 16 is vertically arranged in the housing 11, and the upper surface of the insulating support 16 is horizontally arranged; a connecting terminal 17 is arranged on the cable, and the connecting terminal 17 is placed above the insulating support 16, and the lower surface of the connecting terminal 17 is in contact with the upper surface of the insulating support 16; the conductive member 13 is placed on the connecting terminal 17, and the conductive member 13 is in contact with the upper surface of the connecting terminal 17.

[0057] In this technical solution, the upper surface of the insulating support 16 is horizontally arranged, the lower surface of the connecting terminal 17 can be fitted with the upper surface of the insulating support 16, and the conductive member 13 is fitted with the upper surface of the connecting terminal 17, so that the connecting terminal 17 of the cable can be stably placed on the insulating support 16 in a non-fixed state, and the conductive member 13 can be stably placed on the connecting terminal 17 in a non-fixed state, thereby reducing the difficulty of connection between the conductive member 13 and the cable and improving the disassembly and assembly efficiency of the conductive member 13.

[0058] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the motor stator insulation measurement termination device also includes: a connecting hole and a fastener 18; an internal thread is provided on the inner wall of the connecting hole, and the connecting hole is provided on the upper surface of the insulating support 16; an external thread is provided on the outer wall of the fastener 18, and after the fastener 18 passes through the conductive piece 13 and the connecting terminal 17 in sequence, the fastener 18 is threadedly connected to the connecting hole.

[0059] In this technical solution, after the fastener 18 passes through the conductive member 13 and the connecting terminal 17, the fastener 18 is threadedly connected to the connecting hole, so that the conductive member 13 and the connecting terminal 17 are pressed and fixed on the insulating support member 16 by the fastener 18. By disassembling and assembling the fastener 18, the conductive member 13 can be quickly disassembled and assembled, thereby avoiding insulation damage caused by frequent bending of the cable.

[0060] In this technical solution, the conductive member 13, fastener 18, connecting terminal 17 and insulating support member 16 inside the termination device can be replaced independently, making the termination device more convenient to inspect and repair, and reducing the maintenance cost and failure risk of the termination device.

[0061] Furthermore, a first connecting hole is respectively provided at both ends of the conductive member 13, and a second connecting hole is provided on the connecting terminal 17. After the fastener 18 passes through the first connecting hole and the second connecting hole in sequence, the fastener 18 is threadedly connected to the threaded hole, so that the conductive member 13 and the connecting terminal 17 are pressed onto the insulating support member 16 through the fastener 18, thereby realizing a stable electrical connection between the conductive member 13 and the cable.

[0062] Furthermore, six insulating supports 16 fix the connection terminals 17 of the three first cables 14 and the three second cables 15 in the housing 11 to ensure electrical isolation between the phases and structural stability.

[0063] It is understandable that the connection terminal 17, the cable and the insulating support 16 can be fixedly connected by welding or the like, and it is only necessary to ensure the detachable connection between the conductive part 13 and the cable to ensure that the first cable 14 and the second cable 15 can be disconnected and connected by removing and installing the conductive part 13.

[0064] like Figure 3 As shown, in a feasible embodiment, the terminal 12 includes a plurality of threading openings, which are arranged through the side wall of the housing 11 and are located at different depths of the housing 11; the threading opening of the first terminal 121 corresponds one to one with the threading opening of the second terminal 122.

[0065] In this technical solution, a wire threading hole is provided on the side wall of the shell 11, and the wire threading hole is used to insert the cable. The shell 11 itself can support the cable, so that the termination device has no redundant structure and the overall structure of the termination device is simple; by setting the wire threading hole at different heights on the side wall of the shell 11, the spacing between the cables can be larger, and there is a larger operating space when disassembling and assembling the conductive part 13, and at the same time the electrical safety of the termination device is improved.

[0066] Furthermore, the threading opening of each first terminal 121 is coaxially arranged with the corresponding threading opening on the second terminal 122 to ensure the straightness of the first cable 14 and the second cable 15 after they are connected. The height of the insulating support 16 matches the height of the threading opening of the corresponding cable so that the first cable 14 and the second cable 15 can be on the same straight line after they are connected.

[0067] like Figure 3 As shown, in a feasible implementation manner, the housing 11 includes: a box body 111 and an upper cover 112 , wherein the upper cover 112 covers the box body 111 , and the upper cover 112 is detachably connected to the box body 111 .

[0068] In this technical solution, the first cable 14 and the second cable 15 are connected by the conductive piece 13 and fixed in the box body 111 through the insulating support piece 16. By making the upper cover 112 detachably connected to the box body 111, when it is necessary to perform insulation measurement on the motor, the upper cover 112 can be removed and the conductive piece 13 inside the box body 111 can be removed; when the motor is working normally, the upper cover 112 protects the internal structure of the box body 111, thereby extending the service life of the insulation measurement termination device.

[0069] Furthermore, the housing 11 is made of metal material and has a good protection level, ensuring that the termination device can operate reliably in harsh environments.

[0070] like Figure 1 and Figure 3 As shown, in a feasible implementation, the motor stator insulation measurement termination device also includes: a grounding point 19, which is arranged on the outer wall of the box body 111, the grounding point 19 is located between the two wiring terminals 12, and the grounding point 19 is arranged close to the upper cover 112.

[0071] In this technical solution, the grounding point 19 is located at the upper part of the box body 111, and the grounding point 19 is closer to the cable, so that after the upper cover 112 is disassembled, an insulation meter can be used to quickly measure between the grounding point 19 and the cable, thereby reducing the difficulty of insulation measurement of the motor stator and helping to improve the efficiency of insulation measurement.

[0072] Example:

[0073] A three-phase motor with a rated voltage of 6kV and a power of 1000kW has three power supply cables with a cross-sectional area of ​​70mm 2 The cable has a large hardness and is not easy to bend. When measuring the insulation of the motor stator, it is only necessary to disassemble the upper cover 112 of the housing 11 after the power is turned off, and then remove the six fasteners 18 and remove the three conductive pieces 13, and use the insulation meter to measure the insulation between the grounding point 19 and the cable. After the insulation measurement is completed, the three conductive pieces 13 are fixed between the corresponding first cable 14 and the second cable 15 using the six fasteners 18, and finally the upper cover 112 is reinstalled to complete the entire insulation measurement process, which simplifies the operator's workflow and makes the insulation measurement process more efficient and safe. When the three-phase motor is operating normally, the three power supply cables of the motor are connected to the three power cables of the motor through the conductive piece 13 and form a reliable electrical connection. When the stator insulation measurement is required, it is only necessary to remove the two fasteners 18 at both ends of the cable group conductive piece 13 to disconnect a group of motor power cables from the power supply cable, thereby achieving rapid isolation of the motor stator without removing the power supply cable.

[0074] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0075] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
