Abstract

The invention discloses an external breaking prevention line connector porcelain tube, and belongs to the field of power equipment. The external breaking prevention line connector porcelain tube comprises a tube body, wherein a fuse wire is mounted in the tube body, the tube body is further filled with a flame-retardant filler, a notch is formed in the outer side surface of the tube body, a sealing ring is mounted in the notch, the fuse wire comprises a fusing part and an external breaking prevention part, and the notch is located outside the external breaking prevention part. According to the invention, when the tube body is impacted, the tube body can be broken at the notch, and the notch is still sealed under the action of the sealing ring after being broken, so that the fuse wire is prevented from being exposed, and the condition that the tube body is easy to cause fire breakout under the influence of external breaking factors in the prior art is solved.

Description

technical field

[0001] The invention relates to the field of electric equipment, in particular to an anti-breakage porcelain tube. Background technique

[0002] In our daily production and life, the demand for electricity is inseparable. In daily life, electrical components are widely used. In actual production and life, due to long-term exposure to the sun and rain in the air, air oxidation and other factors, the ring tube at the transformer is likely to cause aging of the ring tube. In order to slow down the aging of the ring tube, corrosion-resistant tubes are usually used Non-metals with strong oxidation resistance and certain flame retardancy are used as the tube material of the Rink tube, such as ceramics. Although this type of material has the advantages of corrosion resistance, oxidation resistance, and high temperature resistance, the disadvantage is that it is relatively brittle. Large, it is easy to be damaged once it is impacted by external force, especially the...

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as Figure 1-3 In the shown embodiment, an anti-breakage ceramic tube includes a tube body 1 of ceramic material, and a fuse is installed in the tube body, and the fuse includes fuses 2 at the left and right ends and two The anti-breakage part 3 between the fuse parts, the diameter of the fuse part is smaller than the diameter of the anti-breakage part, and the pipe body is also filled with a flame-retardant filler 4, and the flame-retardant filler can be quartz sand for use. The outer surface of the pipe is provided with a V-shaped notch on the outer surface of the pipe, and outer legs 5 are arranged on both sides of the notch, and a sealing ring 6 with a circular cross-sectional shape is installed in the notch, and the notch is located at the The outside of the anti-breakage part is located in the middle of the outer surface of t...
