Abstract

The invention relates to a single insulator device for changing a power transmission line with voltage of 35kV or more while powering on / off, which comprises a front and a rear master cards and a connected tension screw rod; a single lock consists of the master cards (1), sub-cards (2) connected with the inner holes of the master cards, and the tension screw rod (3), wherein half of the master card (1) along the inner hole has the connecting structure of movable cover boards (4); the connecting structure is as follows: the movable cover board (4) is hinged with one end of the master card(1) through a hinged pin (5), and the other end is connected with a master card bolt (6); and the sub-cards (2) are configured to be two semicircular barrels respectively fixed into the inner holes (7) of the master cards and the inner holes (8) of the movable cover boards. With the lock, the device has obvious advantage that a single card is suitable for various types of insulators with different model number and is convenient to change with low change cost.

Description

technical field [0001] The invention belongs to the electric power industry, and belongs to the technical field of a jig device structure for replacing a single-chip insulator of a transmission line above 35kV with power on or a power failure. Background technique [0002] At present, the method used to replace the monolithic insulators of transmission lines above 35kV with power on or power off is usually to use closed-type aluminum alloy monolithic cards for replacement. Because there are many specifications and models of insulators used on the line, insulators of each tonnage are divided into common type and anti-pollution type, and insulator steel caps also have many specifications and models, resulting in differences in insulator steel caps, so that the replacement tools can only be equipped one by one Compatible single-chip cards cause troublesome replacement and high cost. The variety and quantity of existing single-chip cards are far from meeting the needs of actual ...
