Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a fully insulated box-type substation cable installation structure. Background Art

[0002] Box-type substation cable is a cable used to transmit electric energy. This cable has a fully insulated design, which can effectively prevent power leakage and short circuit, improve the safety and reliability of power transmission, and is therefore also called fully insulated box-type substation cable. Fully insulated box-type substation cables are usually made of high-quality insulation materials and outer sheath materials to ensure the stability and durability of power transmission. This cable is commonly used in small and medium-sized substations to connect transformers, switchgear and distribution equipment, and is an indispensable and important part of the power system.

[0003] When laying and installing cables, it is easy to cause cable crossing during the pulling process of multiple cables, making the lines chaotic and requiring further inspection during installation, which increases the difficulty of work and reduces work efficiency. In addition, the substation will shake during daily use, so the cable connection has poor stability and short service life. The cable connection is prone to the risk of falling off, affecting equipment operation and even causing fire due to short circuit. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art that there is no fixing mechanism for cables during installation, multiple groups of cables are easily entangled together, which increases the workload during installation, and the cable connections become loose during subsequent use, making it inconvenient to use. A fully insulated box-type substation cable installation structure is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fully insulated box-type substation cable installation structure, including a box-type substation body and a substation assembly, two groups of fixing plates are fixedly installed inside the box-type substation body, and a fixing mechanism is arranged on one side of the substation assembly, and the fixing mechanism includes a support plate, bolts and two groups of rubber pads, a fixing seat is fixedly installed on the top of the support plate, a connecting rod is arranged through the inside of the fixing seat, both ends of the connecting rod are rotatably connected with a rotating rod, two groups of limit rods are fixedly installed on the outer walls of the two groups of rotating rods, and both ends of the connecting rod are fixedly installed with limit plates, and both ends of the connecting rod are provided with a spring.

[0006] Furthermore, a plurality of heat dissipation holes are formed through one side of the box-type substation body, one end of the bolt passes through the interior of the support plate, and one side of the bolt is fixedly connected to one side of the substation assembly.

[0007] Furthermore, one end of the two groups of springs 1 is fixedly connected to one side of the two groups of limit plates respectively, and the other end of the two groups of springs 1 is fixedly connected to the top of the fixing seat.

[0008] Furthermore, one side of one group of rubber pads is fixedly connected to the outer wall of the connecting rod, and one side of another group of rubber pads is fixedly connected to the top of the fixing seat.

[0009] Furthermore, a moving bar is clamped on one side of the fixing plate, a fixing bolt is provided through the inside of the moving bar, and one end of the fixing bolt is connected to the inner thread of the fixing plate.

[0010] Furthermore, a limiting mechanism is provided on one side of the moving bar, and the limiting mechanism includes a fixing rod, a connecting plate, two groups of arc plates and two groups of springs.

[0011] Furthermore, one end of the fixed rod is installed through the inside of the movable bar, one side of the fixed rod is fixedly connected to one side of the connecting plate, one end of the two groups of arc plates are rotatably connected to one side of the connecting plate, one end of the two groups of springs two are respectively fixedly connected to one side of the two groups of arc plates, and the other end of the two groups of springs two are fixedly connected to one side of the connecting plate.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting a fixing mechanism, one end of the cable can be fixed, and the corresponding cable is fixed to one side of the corresponding jack during the pulling process of multiple cables, and then the cables are combed before being inserted into the jack, thereby effectively avoiding excessive pulling of the connection due to the arrangement of the cables in the jack, and also avoiding plugging errors, reducing the labor intensity of the staff, and the box-type substation body will shake in daily use. The fixing mechanism makes the cable connection more stable, thereby extending the service life, and the two sets of rubber pads have a large surface friction, which avoids the cable connection from falling off and affecting the operation of the equipment or even causing a fire due to a short circuit. Since the rubber pad itself is made of rubber material, and the fixing mechanism except for the spring 1 is made of plastic material, the fixing mechanism as a whole has good insulation, so when the cable is installed and fixed, electric shock is effectively avoided.

[0014] 2. In the utility model, by setting a limit mechanism, the installation position of the fixing rod can be selected according to the position of the cable, and the angle of the connecting plate can be changed, so as to facilitate the auxiliary fixation of cables at different angles. In addition, cables of different sizes can be fixed between the two sets of arc plates. The setting of the two sets of springs enables the arc plates to firmly fix the cables, thereby avoiding the cables being dragged inside the box-type substation body, causing the cable connection to be subjected to excessive tension, resulting in disconnection or even damage to the connection, thereby extending the service life and ensuring that the wiring inside the box-type substation body is neat and easy to maintain.

[0023] The effect achieved by the entire embodiment 1 is that when laying and installing the cable, the corresponding cable is placed on one side of the transformer assembly 8, the cable is passed between the connecting rod 64 and the fixing seat 63, and then the two groups of rotating rods 65 are pulled downward. Two groups of long strip-shaped limit grooves are opened inside the fixing seat 63. When the rotating rod 65 is pulled downward, the four groups of limit rods 66 will pass through the long strip-shaped limit grooves. At this time, the two groups of springs 67 are compressed, and then the two groups of rotating rods 65 are rotated so that the top of the rotating rod 65 and the bottom of the fixing seat 63 are in contact with each other. At this time, the two groups of rubber pads 69 are in close contact with the outer wall of the cable. By setting the fixing mechanism 6, one end of the cable can be fixed, and the corresponding cable can be fixed to the corresponding jack during the traction of multiple cables. One side of the cable, and then comb the cable before inserting it into the jack, thereby effectively avoiding excessive pulling of the connection due to the arrangement of the cables in the jack, and also avoiding plugging errors, reducing the labor intensity of the staff, and the box-type substation body 1 will shake in daily use, the fixing mechanism 6 makes the cable connection more stable, thereby extending the service life, and the two sets of rubber pads 69 have a large surface friction, which can avoid the cable connection from falling off and affecting the operation of the equipment or even causing a fire due to a short circuit.

In addition, cables of different sizes can be fixed between the two groups of arc plates 73. The setting of the two groups of springs 74 enables the arc plates 73 to firmly fix the cables, thereby avoiding the cable being dragged inside the box-type substation body 1, causing the cable connection to be subjected to excessive tension, resulting in disconnection or even damage to the connection, thereby extending the service life and ensuring that the wiring inside the box-type substation body 1 is neat and easy to maintain.

[0026] Working principle: When laying and installing the cable, place the corresponding cable on one side of the transformer assembly 8, pass the cable between the connecting rod 64 and the fixing seat 63, and then pull the two sets of rotating rods 65 downward.
