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 the structure of a single-piece insulator replacement fixture device for replacing 35kV-500kV and above transmission lines with power or power failure. Background technique [0002] At present, the method used to replace single-chip insulators of 35kV-500kV and above transmission lines is usually replaced by closed-type aluminum alloy single-chip cards. Since there are many specifications and models of insulators used on the line, each tonnage of insulators is divided into ordinary type and anti-fouling type. In addition, there are many specifications and models of insulator steel caps, which cause differences in insulator steel caps, so that replacement tools can only be equipped one by one Suitable single-chip cards cause trouble in replacement and high cost. The variety and quantity of existing single-chip cards are far from being able to meet the needs of actual ...
