Description

Technical Field

[0001] This utility model relates to the field of surge protector MOV varistor technology, specifically to a safe surge protector MOV. Background Technology

[0002] Surge protectors, during use, are subject to repeated lightning strikes, multi-pulse high currents, and multiple operational overvoltages, leading to aging and instantaneous failure of the MOV (Mechanical Oscillator). During this instantaneous failure, a significant portion of the internal disconnectors in surge protectors fail to disconnect in time. Furthermore, the breakdown points of the MOV during failure are often uncontrollable, potentially damaging the surge protector's disconnection mechanism. This can result in the surge protector failing to disconnect from the power grid in time, causing a continuous short circuit, which can lead to the surge protector igniting and burning, potentially destroying the entire distribution cabinet system and causing fires. To address the inherent shortcomings of surge protectors, standards were developed to install external disconnectors such as fuses or SCBs (Self-Propelled Circuit Breakers) upstream of the surge protector for enhanced safety and fire prevention. However, the installation of external disconnectors has also caused numerous problems, including malfunctions such as disconnection during lightning strikes, failure to disconnect during power frequency currents, or slow disconnection leading to instantaneous breakdown and fire.

[0003] Surge protectors often fail to disconnect from the power grid instantly upon momentary failure, leading to fires or even conflagrations. Adding a surge protector to an external disconnector results in complex wiring and high costs. Furthermore, adding a surge protector to an external disconnector leads to high power consumption (UP).

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A surge protector (MOV) includes an MOV body, the MOV body being externally covered with a protective device for isolating all impact flames generated when the MOV body is punctured. The MOV body has a first electrode and a second electrode on its two sides, respectively. The first electrode includes a first connecting piece, and a first lead extends forward from one side of the first connecting piece. The second electrode includes a second connecting piece, and a second lead extends forward from one side of the second connecting piece and is bent forward.

[0008] Preferably, the protective device includes a housing, the MOV body is covered with a high-temperature resistant material, and the MOV body is embedded in the housing.

[0009] Preferably, the protection device comprises a shell, the MOV body is embedded in the shell, and a cover plate is integrally arranged on the shell and covers the opening of the shell. Advantages

[0010] The one or more technical solutions of the MOV of the safety surge protector provided in the embodiments of the present application at least have one of the following technical effects:

[0011] The above technical solutions can solve the problem of the burning of the surge protector by 100%, guarantee the timely disconnection of the internal disconnector of the surge protector when the surge protector is aging, and achieve safety. The external disconnector installed in front of the surge protector to prevent the surge protector from catching fire can be reduced, a large amount of materials, manpower and resources can be saved, project investment costs can be reduced, and a large amount of social stock resources can be saved, so that the surge protector can be quickly popularized as the overvoltage protection umbrella of all electrical appliances. The reduction of the external disconnector reduces the UP value of the second circuit by 2 times. The surge protector has faster tripping response capability. BRIEF DESCRIPTION OF DRAWINGS
