Abstract

The invention relates to a maintenance-free respirator for a transformer and mainly solves the technical problems inconvenient disassembly, time consuming and labor consuming, low construction efficiency and easy clogging of a prior respirator. According to the technical scheme, the maintenance-free respirator comprises a respirator, a respirator pipe and an expander, the expander comprises a three-way ball valve, a relief valve, a gulp valve, an air bag and an air pressure and temperature and humidity sensor, and the air outlet of the air bag is perpendicularly connected with the outlet of the gulp valve, the inlet of the relief valve and the three-way ball valve, the inlet of the gulp valve is connected with the respirator pipe, one end of the respirator pipe is connected with a horizontal connection port of the three-way ball valve, and the other end of the respirator pipe is connected with the respirator, another horizontal connection port of the three-way ball valve is connected with an oil pocket of the transformer, and the air pressure and temperature and humidity sensor is arranged on the pipe connecting the air bag and the three-way ball valve.

Description

technical field [0001] The invention relates to a maintenance-free respirator for transformers, which belongs to the technical field of transformer respiration devices. Background technique [0002] At present, most of the respirators used in domestic transformers are filter chambers made of glass tubes, which are filled with filter materials such as color-changing silica gel. flow out. When the color-changing silica gel changes from blue to light red, it indicates that the adsorbent has been damp, and the discoloration silica gel needs to be replaced. The replacement of the discoloration silica gel is cumbersome and may cause damage to the glass barrel of the respirator, affecting the work efficiency of the operation and maintenance personnel and the equipment. Safety. During this period, according to regulations, the main body gas protection of the transformer needs to be withdrawn, which has a great impact on the reliability and safety of the safe operation of the main ...
