Abstract

Disclosed is a portable test tower for a transmission line insulator string high-voltage performance test. The portable test tower is of a frame structure, bottoms of two supports (3) are fixed together by stone bolts (1) and bases (2) poured by concrete, two synchronous electric hoists (8) with self-locking function are arranged in the middle of a fixing pole arm (5) arranged at the tops of the supports (3), and respectively connected with two ends of a movable pole arm (6) under the fixing pole arm (5) with steel wire ropes (10) through fixing pulleys (12) close to tops of insides of the supports (3), and the movable pole arm (6) and fixing rails (4) arranged inside the supports (3) form guide rail pairs (7). The potable test power for the transmission line insulator string high-voltage performance test is convenient to assemble, and can be used for testing single-string insulator high-voltage performance, and testing interaction of electrical performance among multiphase insulators.

Description

technical field [0001] The invention relates to the field of high-voltage electric power system, in particular to the structural field of a high-voltage performance detection test device for transmission equipment such as transmission line fittings and insulator strings. Background technique [0002] The high-voltage transmission line is an important part of the power system, and the safe and stable operation of the transmission line directly determines the safety and stability of the power system and the reliability of power supply. The operation performance and anti-interference performance of transmission equipment such as insulator strings and line fittings, protection equipment such as lightning arresters and transformers, and secondary equipment and anti-interference performance are the basis for ensuring the safe and stable operation of transmission lines, especially the insulator strings are responsible for the line-to-ground and other The insulation between objects ...
