Abstract

The invention belongs to measuring devices for high-voltage appliances, and particularly relates to an insulation test device for a porcelain insulator. The insulation test device comprises ropes and rods, capable of being fixed to the insulator, of a megger test probe. The insulation test device comprises a first vertical supporting rod and a second vertical supporting rod. The first vertical supporting rod is connected with one end of a horizontal supporting rod through a universal ball, pulleys are arranged on two sides of the body of the horizontal supporting rod, the other end of the horizontal supporting rod is connected with the second vertical supporting rod, and an upper clamp ring and a lower clamp ring are respectively arranged at the upper end and the lower end of the second vertical supporting rod. Each clamp ring consists of two semicircular rings connected by springs, one end of each semicircular ring is connected with the second vertical supporting rod, and measuring heads are arranged on the inner walls of the ends of the semicircular rings and are connected with the megger. Pins are arranged on the outer walls of the semicircular rings and connected with one ends of the ropes, and the ropes are wound on the pulleys. The other ends of the ropes are connected with a take-up device arranged on the first vertical supporting rod. The insulation test device can be used for rapid and effective insulation test of single insulators forming a porcelain insulator string.

Description

technical field [0001] The invention belongs to a measuring device for a high-voltage electrical appliance, in particular to a porcelain insulator insulation testing device. Background technique [0002] The insulator string is composed of iron caps at both ends of multiple insulators connected to each other. It is an important device for isolating live equipment. Therefore, it is particularly important to test the insulation performance of the insulator string regularly. At present, the usual method for measuring the insulation performance of porcelain insulators is: when the electrical equipment is powered off, the maintenance personnel will lift the platform to a suitable height by operating the lifting platform of the bucket arm truck, and clamp the scissor-type clips of the shaker test line on the single piece. Put the iron caps on both ends of the porcelain insulator, and then operate the lifting platform of the bucket arm truck to keep the personnel at a certain safe...
