Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage disconnect load switches, specifically relating to an outdoor fully enclosed small high-voltage disconnect load switch. Background Technology

[0002] High-voltage disconnect load switches are key equipment in power systems, primarily used for electrical isolation and load switching in high-voltage circuits. Combining the characteristics of disconnect switches and load switches, they provide a clear isolation point when disconnecting the circuit, ensuring operational safety, while also possessing the ability to interrupt rated load current. This equipment is commonly used in substations, distribution networks, and other similar scenarios, and is suitable for power systems with high voltage levels. Its core functions include: isolating power supply, interrupting load current, preventing misoperation, and ensuring safety during equipment maintenance. The design of high-voltage disconnect load switches must meet stringent insulation, arc-extinguishing, and mechanical performance requirements to ensure stable and reliable operation in high-voltage environments.

[0003] Small high-voltage disconnect load switches are typically used in outdoor environments, which are complex and changeable, making it easy for dust or moisture to enter the switch and affect its normal operation. In addition, the sealing performance of the sealing material will gradually decrease after long-term use. However, the design of traditional switch devices often does not have the function of easily replacing the sealing material, making it inconvenient to replace the sealing material and further affecting the performance and reliability of the switch.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figure 1-6 This is an embodiment of the present invention, which provides an outdoor fully enclosed miniature high-voltage disconnecting load switch, comprising:

[0029] The switching mechanism 100 includes a housing 101, a switch body 102 disposed inside the housing 101, a fixed frame 103 fixedly installed on the outside of the housing 101, and a crank arm 104 rotatably installed on the outside of the fixed frame 103.

[0030] The sealing mechanism 200 includes two sealing components 201 for sealing the interior of the housing 101, and a replacement component 202 for easy replacement of the sealing material.

[0031] The sealing component 201 seals the inside of the housing 101, which effectively improves the sealing performance of the inside of the housing 101 and solves the problem of poor sealing performance of the traditional housing 101. This prevents dust and moisture from entering the inside of the housing 101 and prevents adverse effects on the switch body 102. At the same time, the design of the replacement component 202 makes it easy to replace the sealing gasket 201b, ensuring the performance of the sealing gasket 201b.

[0032] Specifically, the sealing assembly 201 includes a sealing plate 201a fixedly installed on the outside of the housing 101, a mounting groove formed on the surface of the sealing plate 201a, a sealing gasket 201b disposed inside the mounting groove, a mounting bracket 201c snapped into the mounting groove by a replacement assembly 202, a fixing bracket 201d fixedly installed inside the mounting groove, and an arc-shaped spring piece 201e fixedly installed on the surface of the fixing bracket 201d.

[0033] Furthermore, the surface of the mounting bracket 201c is provided with a connecting groove for use with the arc-shaped spring piece 201e, and the arc-shaped spring piece 201e passes through the connecting groove.

[0034] Preferably, the arc-shaped spring 201e is used to compress the sealing gasket 201b, the surface of which is raised.

[0035] The surface of the sealing gasket 201b is raised for a tighter fit and improved sealing effect.

[0036] Furthermore, the replacement component 202 includes a side groove 202a formed in the inner cavity of the mounting slot, a spring 202b fixedly installed in the inner cavity of the side groove 202a, a retaining ball 202c fixedly installed on the end face of the spring 202b, and a retaining groove 202d formed on the surface of the mounting bracket 201c and used in conjunction with the retaining ball 202c.

[0037] The spring 202b is used to compress the ball 202c, which improves the stability of the ball 202c being engaged with the inside of the slot 202d. Since the surface of the ball 202c is curved, it facilitates the installation and removal of the mounting bracket 201c, and further facilitates the replacement of the sealing gasket 201b.

[0038] Specifically, the replacement component 202 also includes two limiting blocks 202e fixedly installed in the inner cavity of the side groove 202a. The limiting blocks 202e are used to limit the movement of the ball 202c.

[0039] The limiting block 202e is used to limit the ball 202c to prevent the ball 202c from leaving the inside of the side groove 202a and affecting the installation of the mounting bracket 201c.

[0040] Furthermore, the sealing gasket 201b is an elastic sealing gasket, and the sealing gasket 201b is made of silicone rubber.

[0041] Among them, the sealing gasket 201b, made of highly elastic material, can fit tightly to the joint surface to ensure a sealing effect.

[0042] During use, the sealing gasket 201b is used to increase the sealing between the sealing plate 201a and the housing 101, preventing dust and moisture from entering the interior of the housing 101 and affecting the use of the switch body 102.

[0043] When it is necessary to replace the gasket 201b, remove the gasket 201b from the inside of the mounting groove, so that the ball 202c disengages from the inside of the groove 202d, until the entire gasket 201b is completely removed from the inside of the mounting groove.

[0044] Next, install the new sealing gasket 201b. Align the sealing gasket 201b with the mounting groove and squeeze it in. The sealing gasket 201b drives the mounting bracket 201c into the interior of the mounting groove. The surface of the mounting bracket 201c will compress the retaining ball 202c, causing the retaining ball 202c to be housed inside the side groove 202a. At this time, the spring 202b is in a compressed state. When the retaining groove 202d moves to the retaining ball 202c, the spring force of the spring 202b will cause the retaining ball 202c to spring open and engage with the inner cavity of the retaining groove 202d, limiting the mounting bracket 201c and further limiting the sealing gasket 201b. At the same time, the arc-shaped spring piece 201e compresses the sealing gasket 201b, causing the surface of the sealing gasket 201b to bulge.

[0045] In summary, by sealing the interior of the housing 101 with the sealing component 201, the sealing performance of the interior of the housing 101 is effectively improved, solving the problem of poor sealing performance of the traditional housing 101. This prevents dust and moisture from entering the interior of the housing 101 and avoids adverse effects on the switch body 102. At the same time, the design of the replacement component 202 facilitates the replacement of the sealing gasket 201b, ensuring the performance of the sealing gasket 201b.
