However, due to the high cost of the current wall-piercing sleeve, the product production cycle is longer, especially the shed parts on it, the structure is complex, and the manufacturing cost is high. When the wall-piercing sleeve is used as a test sample for testing, it will be greatly improved. Increase the test cost, but also cause a lot of waste

Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0033] Such as figure 1 As shown, the anti-seismic test sample of UHV DC composite wall bushing according to the present invention includes a bushing body 100 and a smooth silicon rubber film, and the silicon rubber film surrounds the bushing body 100 at least once and It is fixed on the sleeve body 100 to form a sheath 200 sleeved on the sleeve body 100 , and the sheath 200 is uniformly arranged along the axial direction of the sleeve body 100 . During the seismic test of the wall bushing, only the mechanical properties of the product in the earthqu...

The invention discloses an extra-high-voltage direct-current composite wall bushing anti-seismic testing sample and a manufacturing method thereof. The extra-high-voltage direct-current composite wall bushing anti-seismic testing sample comprises a bushing body and a silicon rubber film. The silicon rubber film is wound around the bushing body by at least one circle and fixed on the bushing body to form a sheath, and the sheath is arranged in the axial direction of the bushing body. According to the extra-high-voltage direct-current composite wall bushing anti-seismic testing sample, under the condition that a product balance weight is not changed, an umbrella skirt structure on the outer surface of a wall bushing is replaced with the sheath, and the structure of the bushing body is not changed; as the mass of the sheath is designed to be equal to or nearly equal to the mass of the umbrella skirt structure and the bushing body is evenly covered with the sheath, it can be guaranteed that the mass of the testing sample is equal to or nearly equal to the mass of a true product, the seismic resistance of the bushing body in the sample can be tested, and the influence of the mass of an umbrella skirt on the seismic resistance of the bushing can be effectively simulated. The original umbrella skirt of the complex structure is replaced with the sheath, and therefore the structural characteristics and the manufacturing technology of the testing sample are greatly simplified.
Description
technical field [0001] The invention relates to the technical field of anti-seismic tests of wall-piercing bushings, in particular to an anti-seismic test sample of UHV DC composite wall-piercing bushings and a manufacturing method thereof. Background technique [0002] With the development of my country's power transmission and transformation projects in the direction of high voltage, ultra-high voltage and ultra-high voltage, a large number of key equipment are equipped in DC converter stations, such as DC wall bushings. The wall bushing is mainly composed of a bushing body and an umbrella skirt sheathed on the bushing body. It is suspended and installed on the frame of the valve hall, which is the weak link in the power system for earthquake resistance. Therefore, in areas with strict seismic requirements, the seismic performance check and inspection should be carried out. However, due to the high cost of the current wall-piercing sleeve, the product production cycle is ...
