Technical Field

The invention relates to the field of salt density test operation of high-voltage transmission lines, in particular to a suspension device for a salt density test insulator string.

Background

In order to evaluate the pollution degree of the environment where the line is located, a transmission line operation and maintenance unit needs to perform salt deposit density test work frequently. Namely, the salt density testing insulator is hung on an operation line, and the salt density and the ash density of the filth attached to the testing insulator are tested by regular rotation. According to the latest requirements of national grid companies on salt density test insulators, the salt density test insulator string at least consists of 7 insulators. The conventional method is as follows: the insulator string consists of 3 insulators and is bound at the cross arm of the operation tower by a #8 iron wire. There is no special hanging point hardware fitting for fixing the insulator string. If the #8 iron wire binding mode is continuously used, the following defects exist:

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

(2) if the binding iron wire is not operated properly, the danger of line short circuit tripping is caused, and meanwhile, the operation personnel are seriously injured;

(3) the binding of the iron wire consumes long time, and the working efficiency is influenced.

When the insulator string is hung and rotated for salt density test, the salt density test insulator string is reliably fixed, the insecure fixation is avoided, the safe operation of live working is ensured, the labor intensity of equipotential operation personnel is reduced, and the working efficiency is improved.

In order to achieve the purpose, the invention adopts the following technical scheme:

a suspension device for a salt density test insulator string comprises an insulator fixing ball head, a first angle steel fixing screw, a second angle steel fixing screw, an angle steel fixing clamping block and a nut; the insulator fixing ball head is connected with one end of a first angle steel fixing screw, the other end of the first angle steel fixing screw is a stud, and an angle steel fixing clamping block and a nut are sequentially arranged on the stud; one end of the second angle steel fixing screw is provided with a shaft sleeve which is sleeved on the first angle steel fixing screw, the other end of the second angle steel fixing screw is provided with a stud, and the angle steel fixing clamping block and the nut are sequentially arranged on the stud; the two angle steel fixing clamping blocks are respectively clamped and fixed on two right-angle sides of the high-voltage tower angle steel, and the insulator string is installed on the insulator fixing ball head.

The angle steel fixing clamping block is provided with a round hole matched with the stud and an inclined plane matched with the angle steel.
