Description

Technical Field

[0001] This application relates to the technical field of low-voltage switchgear and control equipment, and in particular to a protective device for outdoor switchgear. Background Technology

[0002] With the development of society and the economy, the application scenarios of switchgear have shifted from indoor to outdoor installation. When installed outdoors, the problem of rain protection needs to be solved. To solve this problem, the primary and secondary incoming (outgoing) lines of traditional outdoor switchgear are mainly routed out from the bottom or side of the switchgear by adding a rain cover.

[0003] When the path of the conductor needs to go upwards, entering (exiting) the conductor from the bottom or side will increase the length of the conductor and the difficulty of installation, thereby increasing the installation cost and affecting the aesthetics. Rainwater will flow into the outdoor switch cabinet from the side opening along the conductor.

[0004] Regarding the aforementioned technologies, the inventors believe that when the conductor path needs to be upward, rainwater will flow into the outdoor switch cabinet from the side opening along the conductor, causing damage to the instruments inside the switch cabinet. Utility Model Content

[0005] The purpose of this application is to provide a protective device for outdoor switchgear to improve the problem that rainwater will flow into the outdoor switchgear from the side opening when the conductor path needs to be upward.

[0006] The protective device for an outdoor switchgear provided in this application adopts the following technical solution:

[0007] A protective device for an outdoor switch cabinet includes a switch cabinet body, an installation groove is provided on the top of the switch cabinet body, an isolation component is provided on the outer wall of the installation groove, the isolation component corresponds to the wires in the switch cabinet body, a protective component is provided on one side of the switch cabinet body located in the installation groove, the inner wall of the protective component corresponds to the isolation component, and a sealing component is provided on the side wall of the protective component.

[0008] By adopting the above technical solution, an installation groove is opened on the side wall of the switch cabinet body, allowing the wires in the switch cabinet body to extend out of the switch cabinet through the installation groove. The installation groove shortens the distance of the wires and reduces the difficulty of installing wires outside the switch cabinet. An isolation component is installed in the installation groove, and a protective component is installed on the side of the switch cabinet body where the installation groove is opened to protect the isolation component in the installation groove. A sealing component is installed on the side wall of the protective component to seal the protective component, preventing rainwater from flowing into the outdoor switch cabinet from the installation groove on the side wall of the outdoor switch cabinet along the direction of the wires and causing damage to the instruments inside the switch cabinet.

[0009] Optionally, the isolation component includes an isolation member, one end of which near the switch cabinet body is connected to the mounting groove on the switch cabinet body. The isolation member has a communicating connecting groove, and the wires in the switch cabinet body are attached to the connecting groove.

[0010] By adopting the above technical solution, the isolator is set in the mounting groove one. The connecting groove opened on the isolator fits into the wire in the switch cabinet body, sealing and isolating the wire extending from the mounting groove one to prevent rainwater from entering the switch cabinet. At the same time, the isolator reduces the friction between the wire and the side wall of the switch cabinet body, avoiding wire damage that could expose the wire core and cause safety risks.

[0011] Optionally, the switch cabinet body has a protrusion on the outer wall where the mounting groove is opened, and the protrusion has a limiting groove that communicates with the mounting groove. The limiting groove fits against the outer wall of the isolation member.

[0012] By adopting the above technical solution, the protrusion is set on one side of the switch cabinet body where the mounting groove is opened, raising the outer wall of the switch cabinet where the mounting groove is opened by a part. This blocks the rainwater flowing along the outer wall of the switch cabinet, preventing rainwater from flowing into the switch cabinet through the mounting groove and damaging the instruments inside the switch cabinet body. The wires extend through the limiting groove opened on the protrusion, and the outer wall of the isolator fits into the limiting groove, providing a certain support for the isolator. This reduces the possibility of rainwater and dust entering the switch cabinet when the wires bend and the isolator bends simultaneously, creating a gap between the isolator and the mounting groove.

[0013] Optionally, the protective component includes a protective cover, which is disposed on the side of the switch cabinet body where the mounting groove is formed. The side of the switch cabinet body near the protective cover has several fixing holes, and the protective cover has fixing holes corresponding to the fixing holes. Fixing members are disposed in the fixing holes and fixing holes, and the fixing members are disposed in the fixing holes to fix the protective cover to the outer wall of the switch cabinet body.

[0014] By adopting the above technical solution, the protective cover is set on the side of the switch cabinet body where the mounting groove is set, which protects the mounting groove and the isolator. This reduces the possibility that the part of the wire extending out of the switch cabinet body will be exposed to the outside for a long time, and that the wire may be damaged after aging and contacting the protrusion of the isolator near the mounting groove. At the same time, it blocks outdoor moisture and dust from entering the switch cabinet through the mounting groove, thus playing a certain role in waterproofing and dustproofing.

[0015] Optionally, a second mounting groove is provided on one side of the protective cover. The inner wall of the second mounting groove is connected to the sealing component. The wires inside the switch cabinet body are led out along the connecting groove of the isolator and then extend out of the protective cover through the sealing component in the second mounting groove.

[0016] By adopting the above technical solution, the wires in the switch cabinet body are arranged through the second mounting groove on the side wall of the protective cover. The sealing component is placed in the second mounting groove to isolate the wires and the protective components, preventing rainwater from entering the protective cover and affecting the wires and isolation components inside the protective cover.

[0017] Optionally, the sealing assembly includes a first seal, the outer wall of which fits into the second mounting groove on the protective cover, and a fixing groove is provided on the first seal, which fits into the wire in the switch cabinet body.

[0018] By adopting the above technical solution, the sealing element is placed in the mounting groove of the protective cover and fits into the mounting groove. The sealing element seals a portion of the wires in the mounting groove, preventing rainwater from flowing into the protective cover along the wires and damaging the wires in the protective cover.

[0019] Optionally, the sealing element is provided with attachments extending from both the inner and outer sides of the protective cover, and the attachments are in contact with the inner and outer walls of the protective cover.

[0020] By adopting the above technical solution, attachments are provided on both sides of the seal to fit against the inner and outer side walls of the protective cover, further preventing rainwater from entering the protective cover along the side walls.

[0021] Optionally, a second sealing element is provided on the side of the protective cover near the switch cabinet body, and the second sealing element is connected to the side wall of the switch cabinet body.

[0022] By adopting the above technical solution, the second sealing element is set on the side of the protective cover close to the switch cabinet body and connected to the side wall of the switch cabinet body, which further seals the protective cover and the switch cabinet body, and further reduces the possibility of rainwater entering the switch cabinet through the mounting groove one along the side wall of the switch cabinet body.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The isolator is placed in the mounting slot 1. The connecting slot on the isolator fits into the wire in the switch cabinet body to seal and isolate the wire extending from the mounting slot 1, preventing rainwater from entering the switch cabinet. At the same time, the isolator reduces the friction between the wire and the side wall of the switch cabinet body, avoiding wire damage that could expose the wire core and create a safety risk.

[0025] 2. The protrusion is placed on one side of the switch cabinet body where the first mounting groove is opened, raising the outer wall of the first mounting groove of the switch cabinet by a portion. This blocks rainwater flowing along the outer wall of the switch cabinet, preventing rainwater from flowing into the switch cabinet through the first mounting groove and damaging the instruments inside the switch cabinet body. The wires extend through the limiting groove opened on the protrusion, and the outer wall of the isolator fits into the limiting groove, providing a certain support for the isolator. This reduces the possibility of rainwater and dust entering the switch cabinet when the wires bend and the isolator bends simultaneously, creating a gap between the isolator and the first mounting groove.

[0026] 3. The protective cover is placed on the side of the switch cabinet body where the mounting groove is located to protect the mounting groove and the isolator. This reduces the long-term exposure of the part of the wire extending out of the switch cabinet body to the outside, and prevents the wire from aging and coming into contact with the protrusion of the isolator near the mounting groove and breaking. At the same time, it blocks outdoor moisture and dust from entering the switch cabinet through the mounting groove, thus playing a certain role in waterproofing and dustproofing.
