Grounding facilities for power distribution poles}

The present invention relates to a grounding facility for a distribution pole. More specifically, when the main body case that surrounds the lower part of the electric pole and is seated on the ground is coupled to the electric pole, the main case is joined in a one-touch manner by the operation of the locking portion, It is equipped with a roof that guides rainwater flowing along the electric pole to the outside of the main body case to prevent rainwater from flowing into the main case. Installation of the roof part can be easily performed, and the connection panel is pressed toward the ground anchor to connect the ground cable. It relates to a grounding facility for distribution poles that can maintain the electrical connection between the grounding anchor and the grounding cable, and can easily release the pressurization of the connection panel when replacing the grounding cable, thus providing convenience to workers. .

In general, power is transmitted from a power plant to a substation and is transmitted to homes through pole transformers on electric poles along distribution lines that often use concrete electric poles as supports. Distribution lines are classified into underground lines and overhead lines, and underground lines supply relatively stable power. On the other hand, the construction cost is 10 times more than that of overhead lines, and there is a problem that the impact of accidents is large. In particular, considering the aesthetics of the city center, underground lines are preferable, but it is not easy to construct underground lines in existing cities that have already been formed, so the current overhead lines are used. The transmission of power is taking place together.

In addition, in order to supply power that has gone through several stages of transformation at the substation to general consumers such as each home or building, distribution lines such as electric poles installed at regular intervals in each area are used. The distribution lines installed in this way include: In case of high voltage contact or ground fault, abnormal voltage is suppressed by ensuring the operation of the protection relay, and grounding is used to protect devices from abnormal voltage such as lightning and surge and to prevent various electrical disasters due to electric leakage. This is the way to do it.

On the other hand, grounding protects operators from electric shock and insulates equipment when excessive abnormal voltages such as lightning or switching surges intrude into power circuits or electronic devices, due to accidents in power equipment or poor insulation. Connecting electrical terminals to the ground not only prevents destruction but also improves functionality to achieve quality information transmission by removing noise from information and communication facilities. In other words, it refers to a means of electrically connecting a metal or conductive object to the ground to make its potential the same as that of the ground or to minimize the potential difference.

Grounding work for distribution lines involves excavating a pit of a certain depth for burying an electric pole, then excavating another pit with a certain depth and width on one side of the pit, and inserting a plurality of grounding rods used for grounding into the pit with a hammer. After burying by hitting using tools such as, the lead wire drawn out from the electric pole and the ground rod are connected in series or parallel. Once the work is completed, the pit is filled with contents such as soil to carry out construction and installation work. You will lose.

It maintains the moved state, and later, when the worker separates the roof part 50 from the main case 10 and operates the separation release part to separate the first case 12 and the second case 14, The grounding facility can be easily removed from the electric pole and replaced with a new grounding facility.

As a result, when the main body case that surrounds the lower part of the electric pole and is seated on the ground is coupled to the electric pole, the main body case is joined in a one-touch manner by the operation of the locking part, and the roof part is provided to guide rainwater flowing along the electric pole to the outside of the main body case. This prevents rainwater from flowing into the main body case, makes it easy to install the roof, and presses the connection panel toward the ground anchor to keep the ground cable and ground anchor electrically connected. When cable replacement work is in progress, the pressurization of the connection panel can be easily released, making it possible to provide a grounding facility for distribution poles that can improve the convenience of workers.

The present invention has been described with reference to an embodiment shown in the drawings, but this is merely illustrative, and various modifications and other equivalent embodiments can be made by those skilled in the art. You will understand.

In addition, although the grounding facility for distribution poles has been described as an example, this is only an example, and the grounding facility of the present invention can be used in products other than the grounding facility for distribution poles.

Therefore, the true technical protection scope of the present invention should be determined by the scope of the patent claims below.
