Embodiment Construction

[0065] The principles of the disclosure will now be described with reference to a number of example embodiments illustrated in the accompanying drawings. Although example embodiments of the present disclosure are shown in the drawings, it will be understood that the description of the embodiments is only for those skilled in the art to better understand and thereby implement the present disclosure, and not to limit the scope of the present disclosure in any way. .

[0066] Figure 1a-Figure 1c A lightning arrester 100 according to an embodiment of the present disclosure is shown. The arrester 100 generally includes an active component 110 and a separately fabricated flexible housing 120 . Such as Figure 1a As shown, the active component 110 includes a generally cylindrical lateral surface and extends in a longitudinal direction Y. As shown in FIG. The separately manufactured flexible housing 120 defines an inner bore 121 in the longitudinal direction Y. The inner bore 121...

Abstract

Lightning arrester (100) and method for manufacturing the lightning arrester (100), said lightning arrester (100) comprising: pre-assembled active components (110), extending in the longitudinal direction (Y); and a separately manufactured flexible housing ( 120), defining a hole (121) in the longitudinal direction (Y) and having an opening at the end surface (126) of the flexible housing (120), the flexible housing (120) surrounding the active via the hole (121) The component (110) is arranged and in contact with the active component (110), the contact causes the flexible housing (120) to deform in the circumferential direction (C), and the deformation produces a force exerted on the active component in the radial direction (R). Pressure on part (110).

Description

technical field [0001] Embodiments of the present disclosure generally relate to electrical equipment, and more particularly, to a lightning arrester and a method for manufacturing the lightning arrester. Background technique [0002] Today, surge arresters play a very important role in protecting critical and expensive equipment such as transformers, switchgear, and computing equipment from overvoltage conditions. A conventional surge arrester generally includes an outer insulating housing, a pair of electrodes located on opposite parts of the housing for connecting the arrester between a line potential conductor and ground, and a pair of electrodes stacked between the pair of electrodes for dissipating the surge generated by the overvoltage condition. Multiple varistors for surges in current. [0003] However, such arresters generally have various disadvantages, such as complicated manufacturing and assembly processes, high manufacturing and material costs, and long produ...
