Description

Columnar laying method of uninterruptible bypass cable {method of installing the uninterruptible bypass cable in the air}

The present invention relates to a method of laying a bypass cable used in an uninterruptible bypass method on a column.

Power facilities are continuously expanding in response to the rapid increase in power demand, and as the level of demand for electricity quality from power users increases, even momentary power outages are subject to civil complaints. In order to supply high-quality power during power distribution work, an uninterruptible method is being implemented in which power distribution work is performed without shutting off power.

Distribution work according to the general uninterruptible method usually consists of a moving transformer car, a bypass cable, and a switch for construction. Then, the bypass cable is removed again to complete the distribution work.

However, the conventional temporary power transmission method using the bypass cable is a method in which the bypass cable is installed on the ground as shown in FIG. 1 , but there are many places where it is impossible to install the bypass cable on the ground. For example, it is difficult to install a bypass cable on the ground in an area crossing a road, an area with a lot of vehicle traffic, a regular parking area, or an area with a large number of people. In addition, there is a risk of damage to the bypass cable due to the nature of the uninterruptible power distribution construction, which requires a long working time.

As shown in FIG. 2, this problem can be solved by installing the bypass cable on the column in the uninterruptible bypass method, but since there is no standard for the work procedure, the bypass cable is arbitrarily bundled with the empty communication line for construction. is currently doing.
