Description

Portable 10 kV cable pole protection device

technical field

The invention belongs to the technical field of protection devices for electric power systems, in particular to a portable 10 kV cable pole protection device.

Background technique

At present, in the construction process of 10 kV power lines, when the cables directly buried in the soil or passing through the cable trench need to be connected to the overhead lines, the cables must be introduced upward into the upper part of the pole. As shown in FIG. 1 , in order to protect the cable 1 from being damaged, a cable pole protection tube 3 is usually provided outside the cable 1 at the bottom of the pole 2 . At present, the commonly used cable upper rod protection tube 3 is made of plastic-coated steel pipe with a length of 2 meters, but its disadvantage is that the cable 1 will be inserted into the cable upper rod protection tube 3 before the cable head is made, which is not only time-consuming , laborious, but also cause great difficulty to the construction of cable 1 upper rod after the cable head is made. In addition, since the outer port of the plastic-coated steel pipe is easy to scratch the outer insulation layer of the cable 1 during the penetration process, it will cause hidden dangers to the safe operation of the power line.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a portable 10 kV cable pole protection device.

In order to achieve the above purpose, the utility model provides a portable 10 kV cable pole protection device, which includes two arc-shaped plates with a semicircular cross-section that can be fastened together, multiple hinges and multiple built-in locks. There are multiple hinges installed on the adjacent side of the two arc-shaped plates, and multiple embedded locks are installed on the other side, and the middle part of the upper edge of each arc-shaped plate protrudes upwards A protruding platform is formed, and the parts on both sides of the protruding platform are horizontally bent inward to form a protective cap.

The portable 10 kV cable pole protection device also includes a plurality of rubber protection pads installed on the inner side of the arc plate.

The utility model provides a convenient 10 kV cable rod protection device that adopts a lock-type installation method, and does not need to thread the cable in advance, so it will not cause cable damage and is also convenient for the cable to be mounted. In addition, it also has the characteristics of low production cost, convenient use, strong operational safety, and low requirements on the technical level of operators.

Fig. 1 is a schematic diagram of the state of use of the protection tube on the cable rod in the prior art.

Figure 2 is a schematic diagram of the unfolded state of the portable 10 kV cable pole protection device provided by the utility model.

Fig. 3 is a top view of the structure of the portable 10 kV cable pole protection device provided by the utility model.

Detailed ways

The portable 10 kV cable pole protection device provided by the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 2, Fig. 3 and Fig. 1, the portable 10 kV cable pole protection device provided by the utility model includes two arc-shaped plates 4 with a semicircular cross-section that can be buckled together, a plurality of Page 5 and multiple built-in locks 6; multiple hinges 5 are installed on the adjacent side of two arc-shaped plates 4, and multiple built-in locks 6 are installed on the other side , and the middle part of the upper edge of each arc-shaped plate 4 protrudes upward to form a protrusion 7 , and the two sides of the protrusion 7 are horizontally bent inward to form a protective cap 8 .

The portable 10 kV cable pole protection device also includes a plurality of rubber protection pads 9 installed on the inner side of the curved plate 4 .

Now the usage method of the portable 10 kV cable pole protection device provided by the utility model is described as follows: After the cable 1 is introduced upward into the upper part of the pole 2, the two pieces on the portable 10 kV cable pole protection device The arc-shaped plate 4 covers the outside of the cable 1 at the bottom of the pole 2, and then locks the built-in lock 6. At this time, the outer edge of the protective cap 8 and the inner side of the protrusion 7 will be close to the outside of the cable 1. Insulation layer, so foreign matter cannot fall into the inside of the protector. In addition, since the rubber protection pad 9 is provided on the inner side of the arc-shaped plate 4, the cable 1 can be fixed and protected.
