Description

Balance yoke for built-in insulators {A yoke for uniformly supporting 6 electric wires}

The present invention relates to a balanced yoke for three-internal handicapped devices, and more particularly, even when an imbalance from the outside occurs, such as lateral vibrations caused by wind, a uniform load may be applied to each of the three child drills connected to the balanced yoke. To a balanced yoke for the built-in insulator.

Currently, most of the power supplied to each customer is provided by transmission lines that are installed in almost all areas, such as cities and suburbs. Such types of transmission lines include underground lines that directly bury power lines in the ground, concrete poles and Although there are two overhead lines that support power lines in the air above a certain height on the ground by using insulators, the underground lines have the advantage that they are simple to install because they do not require additional auxiliary devices. Because it is buried in and directly in contact with the earth, there is a problem that it is expensive because the buried power line itself must be manufactured to insulate against surge voltage and commercial frequency voltage. And the percentage of overhead lines continues It is expected to nitrite.

In general, the overhead line consists of a power line for transporting electric power actually supplied to a customer, a overhead line for reducing the lightning voltage induced by a lightning strike, and a neutral line for attracting current generated by an unbalanced factor. have.

The jangjang for supporting the overhead line constructed as described above can be largely divided into two types, such as the supported jangju and built-in jangju, according to the support method of the power line. After cutting by a predetermined length from the overhead processing line, each of the overhead line through a support yoke connected to the other end of the insulating insulators, one end of which is connected to a steel column lord for positioning the overhead line above a predetermined height from the ground. Each of the cut portions was fixedly supported, and a jumper wire was connected to each of the two overhead lines in order to electrically connect the fixedly supported overhead lines.

In the built-in pylons as described above, it is possible to use a single or two insulators connected to the pylons in a single column, but in the case of using a three-layered handicap device, the insulator device is laterally vibrated by wind or else When an unbalanced (unbalanced) load is applied due to external factors, the loads of each child training are different, and there is a problem that a child training or a bracket may be damaged which bears a load higher than the normal load.

Therefore, the present invention was created to solve the above problems, and for the built-in insulator device so that a uniform load can be applied to each of the three insulators connected even when an imbalance factor from the outside such as lateral vibration caused by wind occurs. The purpose is to provide a balanced yoke.
