Description

Technical Field

[0001] The utility model relates to the technical field of main transformer cooling, in particular to a main transformer cooling fog cannon for a transformer substation. Background Art

[0002] The main transformer, i.e. the main transformer, plays a very important role in the substation. Whether the main transformer can operate safely is directly related to the safe operation of the substation. Once the main transformer fails, it may cause the main transformer switch to trip, causing the busbar to lose power and load, affecting the user's power consumption, and bringing many inconveniences to social production and people's lives. In severe cases, explosions and fires may occur, threatening the safety of personnel and the safe operation of other equipment in the substation.

[0003] The temperature is high in summer, and the main transformer of the substation is in full-load operation for a long time. In addition, the insulation performance of the main transformer of the substation decreases due to aging, causing the upper oil temperature of the main transformer of the substation to often exceed 80℃.

[0004] In order to ensure the safe operation of the main transformer of the substation, auxiliary cooling must be carried out for the main transformer of the substation with the upper oil temperature exceeding 80°C. The auxiliary cooling methods currently used mainly include: axial flow fan cooling and fog cannon cooling.

[0005] A mist cannon is used to connect municipal water for cooling. The water contains calcium ions, magnesium ions, sodium ions, potassium ions, carbonate ions and chloride ions. The water mist adheres to the main transformer, which can easily cause corrosion and scaling of the main transformer.

[0006] The use of fog cannons to manually operate switches on site close to the main transformer poses a personal safety hazard.

[0007] In summary, there is an urgent need for a substation main transformer cooling fog cannon that can meet the requirements of remote switching of the fog cannon to ensure the safety of operators while preventing the main transformer from rusting and scaling. Utility Model Content

[0008] The purpose of the utility model is to provide a substation main transformer cooling fog cannon, which has the advantages of meeting the main remote switch fog cannon to ensure the safety of operators while avoiding rust and fouling of the main transformer, so as to solve the problems raised in the above background technology.

[0012] Preferably, a control module is provided in the control electrical box, and the control module is used to receive external signals and control the operation of the switch device in the electrical box.

[0014] The utility model removes calcium ions, magnesium ions, sodium ions, potassium ions, carbonate ions and chloride ions in water through a purification device. The purified water enters the fog cannon to avoid rust and scaling of the main transformer. The electric box is then controlled to remotely control the switch of the fog cannon. It has the advantages of meeting the requirements of the main remote switch of the fog cannon to ensure the safety of the operator while avoiding rust and scaling of the main transformer.
