Description

technical field

Background technique

At present, it is stipulated in the electrical installation engineering regulations that AC withstand voltage test should be carried out on each piece of suspension insulator. Each piece of suspension insulator transported to the site is composed of 4-6 pieces connected in series. The weight is 15kg-18kg, and the weight of a string of 5 pieces reaches 90kg. The number of suspension insulators tested in large-scale substation projects reaches tens of thousands.

In the prior art, the suspension of each string of suspension insulators relies on 2-3 people to carry out loading and unloading by hand. The suspension is very difficult, and the suspension of 3-4 strings requires complicated and tedious rewiring work. If you are not careful, there will be tests. Arcing problems caused by insufficient distance between the electrode and the ground electrode. Although the pressure resistance time of the test is 1 minute, most of the time is spent in the suspension loading and unloading and test rewiring, which consumes a lot of time and manpower, the work efficiency is low, and the construction period is difficult to be guaranteed. The insulator AC withstand voltage test stand can no longer meet the test of suspension insulators in medium and large substations.

Take the test of hanging 4 strings of suspension insulators with 5 pieces in each string as an example. The hanging time of each string needs 2 minutes, and it takes 8 minutes in total. It takes 1 minute for the test, 2 minutes for safety measures, 15 minutes for 5 tests, 8 minutes for disassembly, and 46 minutes to complete the AC withstand voltage of 24 suspension insulators, which consumes a lot of time and manpower.
