[0002] Organic composite solid insulating materials have advantages such as good insulation, high field strength and easy processing, and are used for insulation of power equipment. Their application in power grid equipment is becoming more and more widespread.

[0003] Currently, domestically produced composite solid insulation materials need to undergo high-voltage breakdown testing and arc ignition simulation testing before leaving the factory. Therefore, there is a need for a device that can meet the high-voltage breakdown testing and arc ignition simulation testing requirements of various insulation materials. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-voltage breakdown arc ignition simulation device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A high-voltage breakdown arc ignition simulation device includes a device base, an electrode assembly on the top of the device base, a load assembly on the top of the device base and located outside the middle of the electrode assembly, and a protective component on the top of the device base and located outside the electrode assembly and the load assembly.

[0007] Furthermore, the electrode assembly includes two optical axis fixing brackets symmetrically arranged on the top of the device base. A hand-cranked slide rail screw is rotatably connected between the two optical axis fixing brackets. One end of the hand-cranked slide rail screw passes through the optical axis fixing bracket and is connected and fixed to a handwheel. An optical axis is provided on each side of the hand-cranked slide rail screw. The optical axis is fixed between the two optical axis fixing brackets. A nut moving part is slidably connected on the two optical axes. The middle part of the nut moving part is engaged with the hand-cranked slide rail screw. An electrode rod fixing base is fixed to the top of the nut moving part. An electrode rod fixing support is fixed to the top of the electrode rod fixing base. Electrode rod one and electrode rod two are clamped between the electrode rod fixing support and the electrode rod fixing base.

[0008] Furthermore, a scale is provided on the top of the device base and on the outer sides of both ends of the optical axis.

[0009] Furthermore, a pointer is provided on the top of the device base and on the side of the handwheel.

[0010] Furthermore, the nut moving part includes a first fixing plate and a second fixing plate. The middle part of the first fixing plate is threaded onto the hand-cranked slide rail screw. The two ends of the first fixing plate are slidably connected to the optical axis. The second fixing plate is fixed to the top of the first fixing plate, and the electrode rod fixing base is fixed on the second fixing plate.

[0011] Furthermore, the loading assembly includes two sets of symmetrically arranged loading stage fixing shafts. The loading stage fixing shafts are fixed to the top of the device base by locking nuts. Loading stage brackets are slidably connected to the loading stage fixing shafts. A Phillips-shaped handle bolt is threaded to the outer side of the loading stage bracket. The end of the Phillips-shaped handle bolt penetrates the outer surface of the loading stage bracket and is pressed together with the outer surface of the loading stage fixing shaft. A glass loading stage is placed between two adjacent loading stage brackets. The glass loading stage is located between the electrode rod fixing bases on both sides.

[0012] Furthermore, the protective component includes a protective cover that covers the outside of the electrode assembly and the carrier assembly. A slot is provided on the bottom side of one side of the protective cover to cooperate with the optical axis fixing bracket, and handles are fixed on both outer surfaces of the protective cover.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a technical solution for high-voltage breakdown and arc ignition simulation of insulating materials testing, which is simple in structure, safe and reliable, time-saving and labor-saving, compatible with a variety of test objects, compatible with different testing needs, convenient for distance adjustment and test observation, and improves the safety of personnel.

[0015] This invention uses a slide rail and lead screw to precisely control the distance between the electrode rod and the test sample. It designs an adjustable-height stage to accommodate test samples of various shapes and sizes. The two types of electrode rods and electrode rod fixing supports are compatible with different testing requirements.

[0016] By designing the electrode assembly, the hand-cranked slide rail screw can be adjusted according to the size of different test materials, thereby controlling the distance between the electrode rods on both sides and the insulating material being tested, thus making it compatible with test items of different shapes and sizes.

[0017] The design of the loading component allows the height of the glass stage on the fixed axis of the stage to be adjusted by a knob, Torx handle, and screw, which is convenient for personnel to operate. It is also compatible with multiple test items and different positions of the same test item, making it easy for testers to adjust the position of the test item without having to move the test item back and forth, which would cause test deviation.

[0018] Through the design of the protective components, the protective cover made of transparent acrylic sheet can protect the safety of test personnel and facilitate the observation of the test status. At the same time, the handles on both sides make it easy for users to lift the protective cover. Attached Figure Description

A pointer 16 is provided on the top of the device base 1 and on the side of the handwheel 5. The handle has a scale 200. During testing, the pointer 16 can be used to control the step distance by observing the scale. Through the design of the electrode assembly, the hand-cranked slide rail screw 3 can be adjusted according to the size of different test materials, thereby controlling the distance between the electrode rods on both sides and the tested insulating material, thus accommodating test items of different shapes and sizes.

[0029] See Figures 4-5The loading assembly includes two symmetrically arranged platform fixing shafts 12. The platform fixing shafts 12 are made of 45 steel. Each platform fixing shaft 12 is fixed to the top of the device base 1 by a locking nut 13. A platform bracket 14 is slidably connected to each platform fixing shaft 12.

The corresponding electrode rods can be selected according to the different requirements of the test voltage / current. This device uses a pair of φ6mm (capable of passing 100A current) and a pair of φ12mm (capable of passing 500A current). During the test, first adjust the height of the two stage supports 14 according to the required height. Specifically, adjust the tightness of the knob to adjust the height of the stage support 14 on the stage fixing shaft 12. After the adjustment is completed, tighten the knob to adjust the height of the stage support 14 on the stage fixing shaft 12. Then, press the glass stage 15 on the two stage supports 14 and place the insulating material on the glass stage 15. Next, rotate the handwheel 5 to drive the hand-cranked slide rail screw 3 to rotate and drive the electrode rod fixing support 9 and the electrode rod 10 and electrode rod 21 on the top to move from both sides toward the insulating material on the glass stage 15.
