Description

Technical Field

[0001] This utility model relates to the field of equipment safety, and in particular to a fixing mechanism and a device for preventing the escape of high-voltage conductor metal particles. Background Technology

[0002] Currently, both gas-insulated switchgear (GIS) and gas-insulated transmission lines (GIL) use male-female plug-in connections. During normal operation, thermal expansion and contraction occur, and friction occurs between conductors. During this friction, metal particles are generated. Without any protective devices, these particles will travel within the enclosed conductor under the influence of gravity and electric field. When they accumulate at the supporting insulator, due to certain special operating conditions or other circumstances, the insulator may experience surface flashover, leading to line outage and equipment damage.

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0024] Reference Figures 1-4 This embodiment provides a device for preventing the escape of high-voltage conductor metal particles, including,

[0025] The connector 200 and the sealing assembly 300 disposed on the outer wall of the connector 200, wherein the sealing assembly 300 includes a bellows 301 and a skirt 302 disposed on the outer wall of the bellows 301.

[0026] The umbrella skirt 302 is set in an umbrella shape on the outer wall of the corrugated pipe 301. It should be noted that both the corrugated pipe 301 and the umbrella skirt 302 are made of rubber, which has a certain degree of elasticity and sealing.

[0027] The connector 200 includes a pipe fitting 201 and a plug fitting 202 disposed on one side of the pipe fitting 201. The pipe fitting 201 is a flexible hose that can be used to install various devices, such as linear devices like cables. Figure 3 As shown, a female contact is provided inside the insertion tube 202, which is used to mate with the male contact. When the two are mated, the male contact will enclose part of the female contact.

[0028] The bellows 301 is cylindrical in shape and has a through hole on one side. The bellows 301 is fitted onto the outer wall of the insertion tube 202. The diameter of the through hole in the middle of the bellows 301 is the same as the diameter of the insertion tube 202. Because the bellows 301 is made of rubber, its surface has a certain friction. Therefore, when the bellows 301 is fitted onto the insertion tube 202, the friction will keep the bellows 301 on the insertion tube 202.

[0029] It should be noted that when the female contact is inserted into the male contact, the bellows 301 will be brought into the male contact. In this way, the bellows 301 can block the gap between the two, thereby preventing dust from entering the female and male contacts and preventing metal particles from escaping. At the same time, after the female and male contacts are connected, the umbrella skirt 302 will also cover the male contact, thus covering the connection between the female and male contacts from the outside, which can further prevent metal particles from escaping.

[0030] Reference Figure 1 and Figure 2This embodiment provides a fixing mechanism, including,

[0031] The support assembly 100 includes a connector 101, a curved member 102 disposed on the outer wall of the connector 101, and an arc-shaped member 104 disposed at one end of the curved member 102, wherein, as shown... Figure 1 As shown, the connector 101 is sleeved on the outer wall of the bellows 301. The connector 101 serves as a fastener to prevent the bellows 301 from moving freely. Meanwhile, the arc-shaped part 104 is connected to the outer wall of the umbrella skirt 302, and the two can be connected together with glue.

[0032] The connector 101 is circular in shape and has protrusions on its outer wall. It should be noted that the connector 101 is made of plastic and is insulated as a whole.

[0033] The curved component 102 has a bending portion 103 on one side. It should be noted that the overall shape of the curved component 102 is close to L-shape, and the curved component 102 is made of elastic plastic material. When the curved component 102 is subjected to external force, it will bend. Since the curved component 102 is located on the outside of the umbrella skirt 302, when the umbrella skirt 302 comes into contact with the outer wall of the male contact, it will squeeze the curved component 102 and deform it. In this way, the curved component 102 will generate a reaction force, thereby pushing the umbrella skirt 302 to fit tightly against the outer wall of the male contact. At the same time, if the diameter of the male contact is small, because the curved component 102 is close to L-shape, the curved component 102 can also drive the umbrella skirt 302 to wrap around the outer surface of the male contact.

[0034] One end of the curved member 102 is located at the protrusion of the connector 101, wherein the curved member 102 is fixedly connected to the connector 101.

[0035] The arc-shaped component 104 has a semi-circular shape, and the outer wall of the middle position of the arc-shaped component 104 is connected to the other end of the curved component 102. The arc-shaped component 104 and the curved component 102 are fixedly connected.

[0036] As an alternative embodiment, the arc-shaped component 104 can be replaced to enhance the function of the curved component 102.

[0037] The curved part 102 has a bending part 103 on one side. The shape of the curved part 102 can be set as C-shaped, which enhances the wrapping of the curved part 102. This allows the umbrella skirt 302 to better fit the outer wall of the male contact when dealing with male contacts of different diameters.

[0038] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
