Abstract

The invention discloses a device and method for detecting the airtightness of a transformer respirator. The device comprises a supporting unit, a measuring unit and a processing unit which are adaptive to a respirator body. The supporting unit comprises a main supporting frame and an auxiliary connecting device. The measuring unit comprises a direct measuring unit and an indirect measuring unit which are distributed on the main supporting frame and the respirator body. The processing unit comprises a receiving unit and a processor and is in wireless connection with the measuring unit. The auxiliary connecting device comprises a measuring connecting frame and a measuring flange plate which are both connected with the respirator body. According to the device, the airtightness detecting fixed value of the respirator is set, under fixed pressure, the parameter information such as the temperature, the humidity, the pressure, the weight and the liquid level of the respirator is measured, airtightness detection is conducted through comparison and judgment, the real breathing normal working state of the respirator can also be simulated, a detection simulation purpose is achieved, and the airtightness detection problem before connecting power equipment is put into operation and in the maintenance process is completely solved.

Description

technical field [0001] The invention belongs to the technical field of transformer detection devices, in particular to a device and method for detecting the tightness of a transformer respirator. technical background [0002] In different development periods of power grids at all levels, oil-filled large-scale equipment, such as transformers, high-voltage reactors, and converters, all play an important role, so the respirator device connected to the oil pillow capsule of each equipment is very important , especially for the replacement of silica gel, it has become an important part of daily maintenance. For example, when replacing a large transformer equipped with respirator silica gel above 10kg, the process is often step-by-step: disassemble, pour out the original discoloration silica gel, wipe, and reassemble , Sealing inspection, install new silica gel, connect transformer, put into use. [0003] The utility model patent with the application number 201320762...
