Description

Technical Field

[0001] This utility model relates to an industrial device, and more particularly to a device for installing high-voltage cables, specifically a fixing device for a 35kV high-voltage cable joint. Background Technology

[0002] In petrochemical engineering construction projects, the fabrication and installation of 35kV high-voltage cable joints is a key process in high-voltage power systems, which is related to the safe and stable operation of the power system and the reliability of power supply.

[0003] Currently, in the traditional fabrication of unarmored high-voltage cable joints, there are no measures to fix the joint area. This causes the joint to frequently shrink and disconnect due to the influence of natural temperature changes, increasing the failure rate of the cable and affecting normal production.

[0004] Therefore, improvements are urgently needed to better meet production demands. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the construction of 35kV high-voltage cable joints by providing a fixing device for 35kV high-voltage cable joints. This device can effectively prevent the joints from retracting and becoming disconnected, reduce the failure rate of cable operation, and create favorable conditions for normal production.

The connectors are arranged at intervals in the same direction, and the spacing is adapted to the outer diameter of the 35kV high-voltage cable. A lower fixing member, in the form of a short plate, is disposed between the connecting members, with its two ends connected to the connecting members respectively, so that the 35kV high-voltage cable can rest on the lower fixing member; there are at least two lower fixing members, respectively adjacent to the two ends of the connecting members, and corresponding to the two interconnected 35kV high-voltage cables; and The upper fixing member is Ω-shaped and can be snapped onto the 35kV high-voltage cable; the lower end of the upper fixing member is fixed to different connecting members and presses the 35kV high-voltage cable; there are at least two upper fixing members, each corresponding to two interconnected 35kV high-voltage cables.

[0007] Furthermore, there are four lower fixing members and four upper fixing members, which correspond to each other to form four sets of fixing components; two sets of these fixing components are provided on each 35kV high-voltage cable.

[0008] Furthermore, the lower and upper fixing members in each set of fixing components are fixed together to the connector by bolts.

[0009] Furthermore, the lower fixing member is perpendicular to the connecting member.

[0010] Furthermore, the spacing between the fixing components on each of the 35kV high-voltage cables is the same.

[0011] Furthermore, it also includes an insulating element, which is strip-shaped and made of insulating rubber. Its width is equivalent to that of the lower fixing element, and its length is equivalent to that of the outer diameter of the 35kV high-voltage cable. There are four insulating elements, which are respectively disposed between each set of fixing components and the 35kV high-voltage cable.

[0012] The beneficial effects of this utility model are: This utility model has a reasonable design, simple structure, and is easy to use. Multiple lower fixing parts can be set on the connector, and the cables on both sides of the 35kV high-voltage cable mid-head can be placed on the lower fixing parts. Then, the upper fixing parts are clamped to the cables and connected to the connector, so that the cables on both sides of the 35kV high-voltage cable mid-head are firmly connected to the connector. This effectively prevents the 35kV high-voltage cable mid-head from retracting and disconnecting, reduces the failure rate of cable operation, and creates favorable conditions for normal production.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 and 2 As shown.

[0018] A fixing device for a 35kV high-voltage cable joint includes: a connector 3, a lower fixing component 1, an upper fixing component 5, and an insulating component 2.

[0019] There are two connectors 3, both long straight plates, with a length greater than the width of the 35kV high-voltage cable joint 6. These connectors 3 are spaced apart and aligned in the same direction, with the spacing corresponding to the outer diameter of the 35kV high-voltage cable 4. Preferably, the connector is approximately 2500mm long and has through-hole-shaped mounting holes.

[0020] The lower fixing member 1 is a short plate-shaped component disposed between the connecting members 3. It has through-hole mounting holes at both ends and is connected to the connecting member 3 with bolts to form a stable structure. The 35kV high-voltage cable 4 can be placed on the lower fixing member 1. Preferably, the lower fixing member is perpendicular to the connecting member for easy installation.

[0021] The upper fixing member 5 is Ω-shaped, and the diameter of its arc-shaped portion is adapted to the outer diameter of the 35kV high-voltage cable 4, allowing it to be securely fastened to the 35kV high-voltage cable 4. Simultaneously, the lower end of the upper fixing member 5 is provided with through-hole-shaped mounting holes, which can be bolted to different connecting members 3 to press the 35kV high-voltage cable firmly, thus ensuring a secure connection between the 35kV high-voltage cable and the connecting member.

[0022] There are four lower fixing members 1 and four upper fixing members 5, forming four sets of fixing components. Each set of fixing components includes one lower fixing member and one upper fixing member. During installation, the lower fixing member and the upper fixing member in each set of fixing components are installed together and fixed together to the connector with bolts for easy operation.

[0023] Two sets of fixing components are respectively provided on both sides of the intermediate joint 6 of the 35kV high-voltage cable 4, so that the two sets of fixing components on each side are set on one 35kV high-voltage cable. Moreover, the spacing between the two sets of fixing components on each side is basically the same to ensure a stable connection.

[0024] Both the connector 3 and the lower fixing member 1 are made of 50*5mm hot-dip galvanized flat iron, facilitating connection. The upper fixing member 5 is made of non-magnetic aluminum alloy, which is lightweight and facilitates material standardization. Furthermore, the width of the upper fixing member is approximately the same as that of the lower fixing member, simplifying installation.

[0025] The insulating element 2 is strip-shaped and made of insulating rubber. Its width is approximately the same as that of the lower fixing element 1, and its length is approximately the same as the outer diameter of the 35kV high-voltage cable 4. It can wrap around the 35kV high-voltage cable and serve as a pad between the 35kV high-voltage cable and the fixing assembly to improve insulation protection. There are four insulating elements, each corresponding to one of the fixing assemblies.

[0026] The method of using this utility model is as follows: Install the lower fixing component into place, forming a stable structure with the connector. Then, place this stable structure below the 35kV high-voltage cable, ensuring the cable's mid-joint is centered within it. Next, install the upper fixing component, firmly connecting the 35kV high-voltage cable to the connector. This effectively prevents the 35kV high-voltage cable mid-joint from retracting or detaching, reducing the cable's failure rate and creating favorable conditions for normal production.

[0027] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
