Transformer salt spray test device and test method thereof

Abstract

The invention discloses a transformer salt spray test device and a test method thereof. The transformer salt spray test device comprises a box body, wherein two nozzles are installed on the periphery of a spray pipe, separation rods are installed in the box body at the lower ends of the nozzles at equal intervals, electromagnetic valves are installed at the tops, at the two ends of a motor, of a mixing box, and a bubble tower is installed in a control box. According to the invention, water and sodium chloride are added into feeding boxes, the volume of the water and the volume of the sodium chloride stored in the feeding boxes are detected through liquid level detectors, electromagnetic valves are opened respectively, the water and the sodium chloride stored in the feeding boxes flow into a mixing box, a motor drives a stirring shaft to conduct mixing and stirring in the mixing box, corrosive gas is atomized into corrosive gas mist through nozzles and sprayed into the box body, a transformer is tested after entering, the corrosive gas is heated and subjected to constant-temperature treatment through a heating plate, the corrosive gas in the box body can be promoted to flow in an internal circulation mode after a fan is powered on, and the experiment effect is improved.

Description

technical field [0001] The invention relates to the technical field of salt spray test, in particular to a transformer salt spray test device and a test method thereof. Background technique [0002] With the development of society, people's demand for electricity is also increasing. Most power stations raise the low-voltage electricity output by generators to tens of kilovolts to hundreds of kilovolts of high voltage through the high-voltage transmission network for long-distance transmission. , so the transformer has entered our daily life. The transformer consists of the body (iron core, winding, insulation, lead wire), transformer oil, oil tank and cooling device, voltage regulating device, protection device (moisture absorber, safety airway, gas Relay, oil conservator, temperature measuring device, etc.) and outlet bushing, it is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil an...
