Background

Respirators are an important component of certain devices, such as: the equipment such as the transformer, the capacitor bank and the like all contain respirators which are used for drying moisture in air and preventing transformer oil in an oil conservator from being affected with damp. The respirator is composed of a respirator body, a drying agent and an oil cup, when the color change part of the drying agent reaches 2/3, the drying agent is indicated to be in a dry state, and the drying agent in the respirator needs to be replaced in time, so that the respirator has important significance for ensuring the safe, stable and reliable operation of equipment.

In the case of power equipment such as transformers and capacitor banks, respirators in such equipment are often located close to high-voltage charged parts in the equipment. When replacing a respirator, for safety reasons, it is common practice to: firstly, switching a capacitor bank or a transformer to a switching-off operation (power failure), and for the capacitor bank, switching on a T-knife switch (discharge treatment); therefore, the capacitor bank or the transformer stops working and is in an equipment maintenance state, namely, a maintenance worker carries out the work of disassembling the old respirator and then carries out the replacement of silica gel or the replacement of discolored oil beyond the distance of ensuring enough safety; then, a new respirator is reinstalled; finally, operate the back-gate (close the gate) -let the equipment resume normal power supply.
