Description

Shockproof connector for extra-high voltage underground transmission and distribution lines {Connector for Underground Power Transmission and Distribution}

The present invention relates to an electric shock prevention connector for high voltage underground power transmission and distribution lines.

In general, the extra-high voltage power produced at the supply source is supplied to each customer through the overhead wire (see Fig. 1, Patent No. 10-0857214) or the underground wire.

In other words, the electricity used in each home, office, and large-scale factories is supplied with electricity through substations installed in each region. These substations are installed for the purpose of changing voltage or current and distributing power.

On the other hand, since the overhead wire is installed on the ground, it is not easy to install in the downtown area where a lot of buildings are arranged. Therefore, in recent years, underground pipes are used to supply electric power to each demand source.

That is, the main underground pipe is buried underground, and another branch underground pipe protruding upward and exposed to the ground is buried at a certain point of the main underground pipe, and a power distribution facility is disposed on the upper part of the underground underground pipe exposed to the ground. Power distribution facilities provide power to each source of demand.

On the other hand, when using the underground cable system, the power line (underground cable) converted to commercial power in the substation is connected to a power distribution facility that branches the power to each source usually through the branch underground pipe, in which case it is drawn into the lower portion of the power distribution facility Underground cables are installed in breakers installed in distribution facilities. In addition, power lines branched through distribution facilities are also connected to overhead lines, such as telephone poles.

However, in the past, the power distribution facility was exposed to the outside, so that the power distribution facility was damaged by being attacked by wild animals.

In addition, conventionally, when a fire occurs in the processing wire line, the fire spreads along the power line connected to the processing wire line, a fire occurred in the power distribution facility.

In addition, in the related art, it is not possible to stably support electric wires drawn out from a power distribution facility and connected to a process electric wire line, and thus problems such as disconnection of electric wires occur.

In addition, when infiltration water is introduced into a power distribution facility, a component of a power distribution facility such as a circuit breaker cannot be safely protected, and when the infiltration water is directly in contact with the breaker and the power line, a serious exposure to electrical safety accidents such as an electric short circuit is intact. there is a problem.

Patent Registration 10-0857214 Patent Registration 10-0859863 Patent Registration 10-1022752

The present invention has been invented to solve the above problems, is protected from wild animals, safe from flames from the outside, can stably support the wires drawn from the power distribution facilities, induces the infiltration water falling into the interior The present invention is to provide an electric shock prevention connector for a special high voltage underground power transmission and distribution line that can prevent the electrical short circuit caused by the contact between the main circuit breaker, the auxiliary circuit breaker and the bus bar.

The circuit breaker mounting plate 20 is a plate of synthetic resin material in which the main circuit breaker 2, the auxiliary circuit breaker 3, and the bus bar 4 are installed. In the present embodiment, the main body 10 is connected to the spacer 30. It is installed in the interior, the inner surface of the main body 10 is disposed to be spaced apart at a predetermined interval, respectively.

In particular, the inclination portion 21 which is inclined downward toward the door portion 11 is integrally formed at the upper end of the circuit breaker mounting plate 20 and that the wire fixing portion 22 is installed on the inclination portion 21. And it should be noted that the second coupling portion 23 is provided on the back.

Here, since the inclined portion 21 is inclined toward the door portion 11, even if the falling water falls inside the main body 10, the inclined portion 21 guides the falling water so that the main breaker 2 and the auxiliary breaker 3 ) And the contact with the bus bar (4) at the source, thereby protecting the main circuit breaker (2), the auxiliary circuit breaker (3) and the bus bar (4) from the electrical short circuit and the resulting fire.

In addition, the wire fixing portion 22 is a member having silicon or rubber therein, and according to the present embodiment, the distribution wire L3 inserted through the main body 10 is inserted into the wire fixing portion 22. When the hole formed in the wire fixing part 22 is expanded, the outer surface of the distribution cable L3 is strongly pressed and fixed. As a result, the outer surface of the distribution cable L3 is tightly pressed and tightly sealed, thereby allowing natural sealing. Lose.

Therefore, even though rainwater flows down the distribution wire L3 through the above function, rainwater does not penetrate into the wire fixing part 22 and naturally rainwater is guided through the inclined portion 21 and is accumulated inside the main body 10. Discharged.
