Respirator for double-channel self-pressure-relief type transformer

The invention discloses a respirator for a double-channel self-pressure-relief type transformer, which belongs to the technical field of transformers and comprises an oil cup assembly and two breathing tank assemblies arranged on two sides of the oil cup assembly respectively. According to the respirator, the two independent breathing tank assemblies communicated with the oil cup assembly can be arranged, the two breathing tank assemblies can be alternately used, so that when silica gel particles are replaced, the respirator can also work normally, operation of the transformer is not affected,the silica gel particles are convenient to replace, the practicability is greatly improved, and a self-conduction assembly is further arranged, so that the practicability is improved. When the breathing tank assembly in use is blocked, the self-conduction assembly in a closed state at ordinary times can be automatically conducted, so that gas is exhausted from the other breathing tank assembly, the purpose of automatic p
