A kind of fast processing method of vehicle-mounted main variable respirator

Abstract

The invention relates to a quick treatment method for a vehicle-mounted main transformer respirator. The engine exhaust pipe of the automobile is divided into two paths through the first three-way pipe, one path is connected to the original engine exhaust port through the first electromagnetic valve, and the other path is Provide a heat source for the respirator drying device; the pipeline connected to the exhaust port of the original engine is provided with a first solenoid valve, and when it is necessary to use the hot exhaust gas of the automobile engine as the heat source of the respirator drying device, the first solenoid valve is controlled to close. The invention can directly drive the vehicle-mounted main transformer respirator rapid processing device into the substation, and perform on-site rapid on-line heating and regeneration treatment on the damp main transformer respirator. Heating regeneration is carried out, and all the damp main transformer respirators of multiple substations along the way are processed at one time, which greatly saves manpower and material resources, saves processing time, and greatly improves efficiency.

Description

technical field [0001] The invention relates to the field of processing the moisture fault of the main transformer respirator, in particular to a fast processing method for the vehicle-mounted main transformer respirator. Background technique [0002] Due to thermal expansion and contraction, the transformer oil in the main transformer oil conservator needs a breathing tube with a certain diameter to breathe with the outside atmosphere to balance the internal pressure change of the main transformer. However, due to the large amount of water vapor in the atmosphere, especially In rainy and humid weather, inhaling moisture directly through the breathing tube will cause moisture inside the main transformer and cause damage and accidents. Therefore, a respirator filled with silica gel desiccant is installed at the end of the breathing tube to absorb the moisture in the inhaled air to ensure The air entering the oil conservator of the main transformer remains dry to ensure the sa...

Problems solved by technology

[0003] 1. Bring the qualified and dry silica gel desiccant to the substation site, replace the damp moisture absorbent in the main transformer respirator, bring the replaced desiccant back to the laboratory, put it into the drying box, and perform temperature-controlled heating and regeneration treatment After passing the treatment, put the silica gel desiccant into a sealed bottle and keep it sealed for the next replacement. However, the silica gel is highly hygroscopic, and if it is not properly sealed or stored for a long time, it may be damp and need to be regenerated. Moreover, many substations are located in remote suburbs, and each replacement and treatment requires a lot of manpower and material resources;

[0004] 2. A small amount of imported or counterfeit maintenance-free main transformer respirators have the disadvantage of using electric heating wires (rods) to directly heat and regenerate the damp silica gel desiccant, and silica gel desiccant is a poor heat conductor. The silica gel around the wire is overheated and scorched, the silica gel in the distance has not been heated, and it is expensive, and the general-purpose domestic main transformer respirator cannot be used, and it is not easy to repair if it is damaged, so most of them still use it.
