Description

Technical Field

[0001] This utility model relates to the field of disconnect switch technology, specifically to a dehumidifying disconnect switch. Background Technology

[0002] In power systems, disconnect switches are extremely important devices, undertaking key tasks such as isolating power sources, switching operations, and ensuring maintenance safety.

[0003] Currently, common disconnect switches on the market have revealed some problems in practical applications. Most disconnect switches do not have strong waterproof capabilities. Under harsh conditions such as high humidity, the existing disconnect switch protection is difficult to resist the invasion of a large amount of moisture. Although disconnect switches have a certain protective shell, it is mainly used for dust prevention and protection against small foreign objects, but the waterproof effect is not good. If they are in a high humidity environment for a long time, moisture can easily penetrate into the interior, causing problems such as rusting of metal parts and corrosion of contacts, affecting their normal operation. In severe cases, it may even affect the stability of power transmission and increase the risk of power outage accidents.

[0004] In summary, considering the need to improve the waterproof performance of disconnect switches and mitigate the corrosion of metal contacts by moisture in order to extend the effective service life of disconnect switches, we propose a dehumidifying disconnect switch. Utility Model Content

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] In this embodiment, the dehumidification isolation switch, such as Figures 1-3 The structure shown has a protective part on the outside of the disconnector switch body 1.

[0029] Specifically, in this embodiment, the protective part includes a base 2 for supporting the disconnector switch body 1, such as... Figure 6 As shown in the structure, the base 2 includes a U-shaped seat 21 with side sealing plates 22 installed at both ends. In this embodiment, the disconnecting switch body 1 can be detachably installed on the U-shaped seat 21.

[0030] It is important to note that in order to create an enclosed space, such as Figure 5 As shown in the structure, an outer cover 4 is provided outside the base 2. In this embodiment, in order to facilitate the disassembly and assembly of the outer cover 4, a groove 201 is provided at the bottom of the U-shaped base 21, and an L-shaped locking block 41 corresponding to the position of the groove 201 is provided on the outer cover 4. The L-shaped locking block 41 can be disassembled and installed in the groove 201 by screws.

[0031] In this embodiment, the outer cover 4 is as follows: Figure 5 As shown, the cover on the U-shaped base 21 has a circular structure so that the disconnecting switch body 1 will not conflict with the cover structure when it is opened or closed. A protrusion 211 is provided on the outer side of the upper end of the U-shaped base 21. In order to obtain a sealing structure, an insertion cavity for inserting the dehumidification chamber 3 is provided between the protrusion 211 and the outer cover 4.
