Abstract

The present invention relates to a cable connection apparatus and an uninterruptible power supply distribution method. More specifically, in a conventional uninterruptible power supply distribution method, a heavy construction cable clamp has been connected and demolished by relying on the strength of an electro-pneumatic live wire. In the present invention, the construction cable clamp is towed and lifted by a mechanical operation of the small strength of the electro-pneumatic live wire. In a conventional manner, a temporal cable locker is required to be separately installed, so that the construction cable is held and connected to an extra high-voltage power line. In the present invention, the temporal cable locker is not used, and the cable clamp is held, with an insulating towing belt, in the cable clamp connection apparatus having insulation and lifting functions, and the construction cable clamp held in the cable clamp connection apparatus is directly connected to the extra high-voltage power line if necessary, such that an operation process is simplified, thereby shortening an operation time. It is possible to perform complete electrical connection of the construction cable clamp by a simple mechanical operation without relying on the strength of the electro-pneumatic live wire. Thus, a workload of an operation can be remarkably reduced, thereby enhancing field utility, economical efficiency, and safety.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cable clamp connection device and an indirect live-line uninterruptible power distribution method using the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable connecting apparatus and an uninterruptible power distribution method, and more particularly, to a bypass cable, an uninterruptible power transformer apparatus, An insulation lifting function for performing pulling, pulling, and connecting operations easily and safely, which was impossible to construct due to the worker's labor intensity and physical strength limit when the construction cable is installed by the live wire method. The cable clamp connection device and the indirect live wire Uninterruptible power distribution method.

In the modern society, electric power demand is surging. On the other hand, as the demand level for electric power quality increases, electric power is cut off during operation so as to supply high quality electric power by reducing work interruption during construction for installation and maintenance of distribution line Uninterruptible power distribution system in which construction work is carried out in a state that is not in operation.

Uninterruptible power distribution method using such conventional high voltage distribution line uses uninterruptible temporary transmission method using bypass jumper cable for live wire, construction switch, uninterruptible transformer car, bypass cable, etc. Recently, however, KEPCO will abolish the live wire method from 2017 and introduce the uninterruptible power distribution system using the indirect live-wire method. As the development of tools and construction methods is insufficient to 10% of the whole process, Due to the confusion caused by the combined use of the construction method and the direct live method, it is impossible to utilize the field due to the limitation of labor intensity and physical strength as well as the safety risk of the live wire majors. to be.

Here, in the conventional direct live method, the live wire technique is performed by directly touching the special high voltage in a live wire state by wearing a protective gear, and in order to secure the safety distance, an insulating stick for a live wire of about 2 m in length It is a live operation method in which the operation is carried out without directly touching the high-voltage distribution line of live line.

On the other hand, in order to implement the uninterruptible power distribution method, bypass jumper cable for live wire, construction switch, uninterruptible transformer car, bypass cable and so on are used. In this method, the cable clamp for construction should be directly installed on the extra high voltage power line Followed by jumper line compression.

1, the conventional uninterruptible power distribution method is accompanied by a step of installing the cable clamp 3. First, the cable temporary hook 2 is attached to the extra-high voltage power line 6 by using the stick 5 for the live operation The temporary bypass cable 7 is fixed temporarily to the cable temporary hook 2 by using the stick 5 for live working and then the high voltage power line The cable clamp 3 temporarily fixed to the cable temporary hook 2 is hooked on the extra-high voltage power line 6 from which the cover is removed by using the stick 5 for live wire work again after removing the cover of the cable 6, The cable rotating device is inserted into the cable clamp 3, and then the connecting operation is performed using the rotating function stick for the indirect live wire.

However, in the indirect live uninterrupted power distribution method, the stick for the live wire work of about 2 m long is used for the complicated and troublesome work to perform the work, and the electric wire separator, the live wire compressor (about 4.5 kg) The weight (about 5 ~ 20kg) is put on the end of the stick for live work, so it is impossible to support the stick for live work due to the worker's physical strength. Therefore, the mistake of dropping the cable clamp etc. during work frequently increases labor intensity. The limitation is not only concern about musculoskeletal diseases but also cause safety risk and line failure due to omission of protection. For this reason, we are worried about the indirect live live uninterruptible power distribution technique of the old technology in the live industry and application technology field related industry .

In order to solve the above problems, it is urgent to develop a technique for an efficient indirect live-line uninterruptible power distribution method.
