A salt density test insulator string suspension device

technical field

The utility model relates to the field of salt density testing of high-voltage transmission lines, in particular to an insulator string suspension device for salt density testing.

Background technique

In order to evaluate the pollution degree of the environment where the line is located, the operation and maintenance unit of the transmission line needs to carry out the salt density test frequently. That is to say, on the running line, hang the salt density test insulator, rotate it regularly, and test the salt density and ash density value of the dirt attached to the test insulator. According to the latest requirements of the State Grid Corporation for salt density test insulators, the salt density test insulator string consists of at least 7 pieces of insulators. In the past, the insulator string consists of 3 pieces of insulators, which are bundled with #8 iron wire at the cross arm of the running tower. There is no special hanging point hardware for fixing the insulator string. If you continue to use the #8 iron wire binding method, there are the following shortcomings:

(1) The weight of 7 pieces of porcelain insulators is 16kg, and the iron wire binding is easy to fall off and cause danger;

(2) If the iron wire used for binding is improperly operated, it may cause the danger of short circuit tripping of the line, and at the same time cause serious injury to the operator;

(3) Iron wire binding takes a long time and affects the operation efficiency.
