Description

Bracket equipment for connecting electric power cable in the complex {Bracket equipment of connecting for electric power cable in underground}

The present invention relates to an underground power cable connection bracket facility in a complex, and more particularly, to maintain a constant position of an underground pipe, to remove moisture from the inside, and to prevent damage to power cables in advance. It relates to power cable connection bracket facilities.

Electricity generated at a voltage of about 20,000V in power plants, including thermal power plants, hydroelectric power plants, and nuclear power plants, is boosted to extra-high voltage (154 KV or 345 KV) suitable for transmission, and the boosted electricity is sent to the primary substation through extra-high voltage lines. is transmitted to

The primary substation drops the distributed extra-high voltage electricity to 22.9 KV, which is a special high voltage, and transmits or distributes power to the secondary substations located near large-capacity customers or to each general customer along the distribution lines.

The electricity distributed from the primary substation or the secondary substation is transmitted or distributed to the receiving facilities of each customer through the transmission and distribution system composed of overhead distribution lines and underground distribution lines, and is transmitted and distributed to low voltage customers through extra-high voltage customers, high-voltage customers, and various outdoor transformers. It is used for industrial and household purposes.

There are two types of power transmission and distribution: ground-based and ground-based.

In the transmission and distribution method using the underground, an underground pipe is installed underground, and an underground power cable for transmitting or distributing extra-high voltage is placed in the underground pipe.

After the installation of the underground pipe is completed, remove the wood plywood and spacers and backfill to complete the construction. However, when there is a slope or groundwater leaching, it becomes difficult to maintain the installed position of the constructed underground pipe structure.

In addition, when a certain amount of water permeates the inside of the underground pipe disposed in the complex during the rainy season, the water level in the pipe increases and the power cable is submerged, resulting in an electrical safety accident. In addition, when a certain amount of moisture is formed in the pipe, there is a problem in that the power cable is exposed to moisture as it is.

In addition, when an animal such as a rat penetrates into the pipe and damages the cable, a disconnection occurs and an electrical safety accident occurs.
