Description

Technical Field

[0001] The utility model belongs to the technical field of electrical performance testing, and specifically relates to an electrical performance testing device for insulating materials. Background Technique

[0002] Insulating materials are materials that do not conduct electricity under an allowable voltage, but they are not absolutely non-conductive materials. Under the action of a certain externally applied electric field strength, processes such as conduction, polarization, loss, and breakdown will also occur. Currently, with the development of power technology, solid insulating materials have been widely used in power equipment due to their excellent insulating properties. With the continuous increase of power voltage levels, higher requirements are also placed on the insulating properties of insulating materials. Usually, testing devices are used to test the electrical strength of insulating materials. At the same time, during the testing process of the electrical strength of insulating materials, in order to avoid the occurrence of unexpected discharges such as surface discharges, the test electrodes and insulating materials need to be immersed in transformer oil.

[0003] A document with the publication number (CN219871441U) discloses an electrical performance detection device for insulating materials, which relates to the field of insulating material testing, including a working box. The lower end of the working box is fixedly connected with support columns, the surface of the support columns is fixedly connected with a cross plate, a hydraulic cylinder is installed at the upper end of the cross plate, and the output end of the hydraulic cylinder is fixedly connected with a bottom plate.

[0004] The above device drives the bottom plate through the hydraulic cylinder to lift the entire device, increasing the contact area between the device and the ground, so that the device can be parked more stably. Through the mutual cooperation of the threaded lead screw, the first transmission gear, the second transmission gear, and the rotating motor, the detection mechanism can be moved up and down, avoiding oil leakage caused by poor sealing when penetrating the box body at the lower end.

[0005] The above device only has the ability to clamp and fix and detect insulating materials individually. When multiple insulating materials need to be detected, the insulating materials need to be frequently loaded and unloaded for testing. At the same time, the above device directly fixes the insulating materials through the electrodes. When an operation error occurs, the electrodes always move towards each other, which will cause damage to the electrodes due to continuous extrusion.

[0006] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0007] To solve the technical problem of detecting a single insulating material, the basic concept of the technical solution adopted by the present utility model is:

[0008] An electrical performance testing device for an insulating material, comprising a bracket. The overall shape of the bracket is U-shaped, and sliding rails are symmetrically arranged between the two brackets; mounting blocks are symmetrically arranged on the sliding rails, and the mounting blocks are slidably connected to the sliding rails; a detection component is arranged on the mounting blocks, and the detection component is used to detect the insulating material. The detection component includes a plurality of detection blocks and a plurality of electrodes. Each detection block is elastically connected to the corresponding mounting block, and the plurality of electrodes are arranged in an array on one side of the detection block, and the electrodes are fixedly connected to the detection blocks; an adjustment component is arranged between the mounting blocks, and the adjustment component is used to adjust the position of the detection blocks.

[0009] As a preferred embodiment of the present invention, the detection component further includes a fixed shaft. The fixed shafts are symmetrically arranged on the mounting blocks. One end of each fixed shaft is fixedly connected to the corresponding mounting block, and the detection block is elastically connected to the other end of the fixed shaft.

[0010] As a preferred embodiment of the present invention, the detection component further includes an elastic member. The elastic member is sleeved on the fixed shaft. One end of the fixed shaft is fixedly connected to the mounting block, and the other end of the elastic member is fixedly connected to the detection block (including but not limited to a spring), and the detection block is slidably connected to the fixed shaft.

[0011] As a preferred embodiment of the present invention, the detection component further includes display lights. The plurality of display lights are arranged in an array on the other side of the detection block, and the display lights are fixedly connected to the detection blocks. Each display light is electrically connected to the corresponding electrode.

[0012] As a preferred embodiment of the present invention, the adjustment component includes a plurality of transmission blocks. The transmission blocks are slidably connected to the sliding rails, and the upper ends of the plurality of transmission blocks are fixedly connected to the corresponding mounting blocks.

[0013] As a preferred embodiment of the present invention, the adjustment component further includes a fixed block and a bidirectional threaded rod. The fixed block is fixedly connected to the bottom end of the transmission block, and the two ends of the bidirectional threaded rod are respectively threadedly connected to the fixed block.

[0014] As a preferred embodiment of the present invention, sliders are symmetrically arranged at the bottom end of the transmission block. The sliders are connected to the transmission block through fasteners, and the sliders are slidably connected to the sliding rails. A buckle is arranged between the sliders and the sliding rails.

[0015] As a preferred embodiment of the present invention, the electrodes are electrically connected to a multimeter and a bridge, and the electrodes are electrically connected to a circuit breaker.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] 1. For the electrical property testing equipment of an insulating material, when an operation error occurs, the detection block is driven by the electrode to squeeze the elastic member and deform. The force received by the electrode is buffered and dispersed through the deformation of the elastic member, avoiding the electrodes from always moving towards each other, which may cause damage to the electrodes due to continuous extrusion. This protects the electrodes. At the same time, the force generated by the deformation of the elastic member pushes the detection block outward, the detection block pushes the electrode, and the electrode is tightly attached to the surface of the insulating material under the force of the elastic member.

[0018] 2. For the electrical property testing equipment of an insulating material, when it is necessary to test multiple insulating materials, multiple groups of electrodes are set to test the insulating materials simultaneously, thereby reducing the operation steps and improving the detection efficiency.

[0019] 3. For the electrical property testing equipment of an insulating material, during the detection process, the detection result of the insulating material can be directly observed through the display. When the insulating material exceeds the voltage it can withstand, an open circuit will occur. At this time, the display no longer lights up due to the open circuit of the insulating material. The detection structure of the insulating material can be directly judged through the lighting and extinguishing of the display. At the same time, a multimeter and a Wheatstone bridge are used to ensure the accuracy and reliability of the test.

When it is necessary to test multiple insulating materials, multiple groups of electrodes 21 are set to test the insulating materials simultaneously, thereby reducing the operation steps and improving the detection efficiency. When an operation error occurs, the electrode 21 drives the detection block 2 to squeeze the elastic member 32 to deform, and the force received by the electrode 21 is buffered and dispersed through the deformation of the elastic member 32, avoiding the electrodes 21 always moving towards each other, which may cause damage to the electrodes 21 due to continuous extrusion, protecting the electrodes 21. At the same time, the elastic member 32 pushes the detection block 2 outward through the force generated by the deformation, the detection block 2 pushes the electrode 21, and the electrode 21 is tightly attached to the surface of the insulating material under the force of the elastic member 32. During the detection process, the detection result of the insulating material can be directly observed through the display 22.

The circuit breaker includes a housing, a power-off device, an intelligent self-identification unit, and a conductor fixing housing. Among them, the circuit breaker has been disclosed in an active self-identification circuit breaker and power-off method in the prior art (CN118156092A), and will not be elaborated here.

[0031] Among them, the adjusting component includes a plurality of transmission blocks 5. The transmission blocks 5 are slidably connected to the slide rails 4. The upper ends of the plurality of transmission blocks 5 are fixedly connected to the corresponding mounting blocks 3. The adjusting component further includes a fixed block 51 and a bidirectional threaded rod 52. The fixed block 51 is fixedly connected to the bottom end of the transmission block 5.

The sliders 41 and the transmission block 5 are connected by fasteners. The fasteners include but are not limited to bolts. The sliders 41 are slidably connected to the slide rails 4. A buckle is provided between the sliders 41 and the slide rails 4. Manually place the cut-insulated material between the electrodes 21. At this time, manually rotate the threaded rod 52. When the threaded rod 52 rotates, it is thread-driven through the opposite thread directions at both ends, driving the fixed blocks 51 at both ends to move towards each other. Through the opposite movement of the fixed blocks 51, the corresponding transmission blocks 5 and sliders 41 are driven to move towards each other on the slide rails 4. The corresponding mounting blocks 3 are driven to move towards each other through the transmission blocks 5, and the corresponding detection blocks 2 are driven to move by the mounting blocks 3, so as to clamp and fix the insulating material between the opposite electrodes 21.

[0032] Working principle: Manually place the cut-insulated material between the electrodes 21. At this time, manually rotate the threaded rod 52. When the threaded rod 52 rotates, it is thread-driven through the opposite thread directions at both ends, driving the fixed blocks 51 at both ends to move towards each other. Through the opposite movement of the fixed blocks 51, the corresponding transmission blocks 5 and sliders 41 are driven to move towards each other on the slide rails 4. The corresponding mounting blocks 3 are driven to move towards each other through the transmission blocks 5, and the corresponding detection blocks 2 are driven to move by the mounting blocks 3, so as to clamp and fix the insulating material between the opposite electrodes 21. By setting multiple groups of electrodes 21 to simultaneously test the insulating material, when an operation error occurs, the electrodes 21 drive the detection blocks 2 to squeeze the elastic members 32 to deform. Through the deformation of the elastic members 32, the force received by the electrodes 21 is buffered and dispersed, avoiding the electrodes 21 from always moving towards each other, which may cause damage to the electrodes 21 due to continuous extrusion, and protecting the electrodes 21. At the same time, the elastic members 32 push the detection blocks 2 outwards through the force generated by the deformation. The detection blocks 2 push the electrodes 21, and the electrodes 21 are tightly attached to the surface of the insulating material under the force of the elastic members 32. During the detection process, the detection results of the insulating material can be directly observed through the display 22. When the insulating material exceeds the voltage it can withstand, a circuit break will occur. At this time, the display 22 no longer lights up due to the circuit break of the insulating material. The detection structure of the insulating material can be directly judged through the lighting and extinguishing of the display 22. At the same time, a multimeter and an electric bridge are used to ensure the accuracy and reliability of the test.
