Description

Technical Field

[0001] The present invention relates to the technical field of lightning arrester equipment, and specifically to a 10kV porcelain outer casing lightning arrester encapsulation end cover and an encapsulation method therefor. Background Art

[0002] In recent years, the market for 10kV porcelain outer casing lightning arresters has been getting smaller and smaller. Currently, they are mainly used in the hot southern regions and the northwestern desert regions of our country because their ultraviolet resistance and sand and wind resistance are much stronger than those of composite outer casing lightning arresters. However, their production qualification rate is low, the cost is high, and the assembly is troublesome, so manufacturers are reluctant to produce them. This has led to the use of composite outer casing lightning arresters for protecting circuits in the southern regions and the northwestern desert regions as well. The outer casing of the composite outer casing lightning arrester ages rapidly under ultraviolet light and is not resistant to sand and wind, often resulting in cracks in the outer casing and only the internal components remaining, which cannot protect the power operation well. Currently, there are some drawbacks in the installation method of the sealing cover, such as deformation and gaps, which affect the sealing performance and are easily invaded by water vapor; when the sealing cover is sleeved, the porcelain outer casing of the lightning arrester needs to bear a certain force, and excessive force is likely to cause damage to the porcelain outer casing. Therefore, it is necessary to protect the porcelain outer casing during assembly.

[0003] The production process of porcelain outer casing lightning arresters is troublesome. Their sealing end covers need to be sealed by a hemming machine. Due to port deformation and bumping phenomena during the firing process of the porcelain bottles, which are inevitable, this causes the porcelain bottles to be crushed by extrusion when being encapsulated by the hemming machine, and may also cause cracks or poor sealing inside the encapsulated porcelain bottles, resulting in unqualified products. Now, a 10kV porcelain outer casing lightning arrester encapsulation end cover and an encapsulation method have been invented to solve the above problems. Summary of the Invention

[0004] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides a 10kV porcelain outer casing lightning arrester encapsulation end cover and an encapsulation method therefor to solve the above problems.

[0005] (II) Technical Solutions To achieve the above object, the present invention provides the following technical solutions: A kv porcelain outer casing lightning arrester encapsulation end cover includes an encapsulation end cover, engaging sawteeth, a wiring screw, and a porcelain outer casing lightning arrester. A wiring screw is welded to the top of the encapsulation end cover, and engaging sawteeth are provided at the bottom of the encapsulation end cover. The porcelain outer casing lightning arrester is composed of an encapsulation end cover, a sealing washer, a spring, an arrester core body, and a porcelain bottle. Engaging grooves are provided at both ends of the porcelain bottle, a sealing surface is provided at the port of the porcelain bottle, an arrester core body is placed inside the porcelain bottle, a spring is placed on the top of the arrester core body, and sealing washers are provided at the top and bottom of the porcelain bottle.

[0006] Preferably, the engaging sawteeth are engaged inside the engaging grooves, and the diameter of the port of the encapsulation end cover is greater than the diameter of the side edge of the top of the encapsulation end cover.

[0007] Preferably, the diameter of the encapsulation end cap is larger than the port diameter of the porcelain bottle. There are two encapsulation end caps, and both of the two encapsulation end caps are sleeved on both ends of the porcelain bottle.

[0008] Preferably, the port shape of the porcelain bottle is an S-shaped port, the distance of the sealing surface is greater than 5 mm, and the depth of the buckling groove is greater than 3.5 mm.

[0009] Preferably, one end of the spring away from the arrester core body abuts against the inner top wall of the encapsulation end cap, and the inner wall of the encapsulation end cap abuts against the sealing gasket.

[0010] Preferably, a chamfer is provided on the outer surface of the encapsulation end cap, and the maximum diameter of the porcelain bottle is larger than the maximum diameter of the encapsulation end cap.

[0011] Preferably, one end of the arrester core body away from the spring abuts against the inner bottom wall of the encapsulation end cap. The length of the arrester core body is less than the length of the porcelain bottle, and the diameter of the arrester core body is less than the minimum diameter of the porcelain bottle.

[0012] Another technical problem to be solved by the present invention is to provide a method for encapsulating an end cap of a 10 kV porcelain outer casing arrester, including the following steps: 1) The encapsulation end cap is formed by stamping tinplate in a mold, and then a wiring screw is welded at the center position of the end. Its structure is simple and easy to process; 2) The circumference of the encapsulation end cap is provided with serrations, and the number thereof is adjusted according to the port size of the porcelain bottle, but the number is ensured to be a multiple of three; 3) Adsorb the encapsulation end cap on the circular port of the encapsulation tooling mold, align it with the porcelain bottle port and press it down. As the pressing process progresses, the buckling serrations provided on the encapsulation end cap are deformed under the extrusion of the tooling mold and buckle at the buckling groove position of the porcelain bottle port; 4) Install the encapsulation end cap at the bottom end of the porcelain bottle. Adsorb the encapsulation end cap on the circular port of the encapsulation tooling mold, align it with the porcelain bottle port and press it down. As the pressing process progresses, the buckling serrations provided on the encapsulation end cap are deformed under the extrusion of the tooling mold and buckle at the buckling groove position of the porcelain bottle port. At this time, the bottom end of the porcelain bottle is sealed by one encapsulation end cap, and the encapsulation end cap abuts against the sealing gasket located at the bottom end of the porcelain bottle to improve the sealing performance of the connection; 5) Place the arrester core into the inner cavity of the porcelain bottle. At this time, the bottom of the arrester core abuts against the inner bottom wall of the encapsulation end cover that has been installed at the bottom end of the porcelain bottle. Then, place the spring. Finally, snap another encapsulation end cover onto the upper end of the porcelain bottle. At this time, the spring abuts against the inner top wall of the encapsulation end cover installed at the upper end of the porcelain bottle. Adsorb the encapsulation end cover onto the circular port of the encapsulation tooling mold, align it with the port of the porcelain bottle, and press it down. As the pressing process progresses, the snap-in serrations provided on the encapsulation end cover deform under the extrusion of the tooling mold and snap into the snap-in groove position of the porcelain bottle port. At this time, both ends of the porcelain bottle are closed through the encapsulation end cover. Through the setting of the sealing surface and the sealing gasket, the sealing performance at the connection between the encapsulation end cover and the porcelain bottle is improved; 6) The encapsulation end cover is made of tinplate and is formed by one-time stamping in the mold. Its circumference is provided with snap-in serrations, which are matched with the size of the porcelain bottle port so that it can be firmly fixed at the porcelain bottle port after being snapped. A wiring screw is welded at the center position of its end for connecting the high-voltage and low-voltage terminals of the arrester.
