Coupling device with construction protective equipment of overhead distribution line

摘要

The present invention is a 23kV building protective pipe that is already developed and distributed in order to prevent disasters caused by contact of construction equipment or live parts due to worker's mistakes in various construction sites close to high or special high-voltage overhead lines. The charging part is protected, and the newly developed overhead line insulation cover will be used for the interior of the overhead line. ; Utility Model Application No.20-2009-0001273 (2009.02.05) ; By using the above two protection devices, the processing distribution line approaching the construction site is protected by the charging section, so that safety can be ensured even when contacting the construction machinery equipment or the charging section due to the operator's mistake. ; However, the two types of protection devices are separate and separate, and there is a risk that the protection of the connection part will be inadequate, thus preventing safety. With this in mind, we developed and connected the connecting mechanism to connect the insulation cover for live line work with the 23kV building protection pipe securely. Its purpose is to prevent disasters caused by exposure to live parts due to movements with hospitals. ; Insulation cover, overhead distribution line, 23kV building protection pipe, interior parts, live work, charging part, polymer type suspension insulator, self-forming suspension insulator
