A water-cooled inverter ultra-pure coolant filling storage filling device and filling method

Abstract

The invention relates to the field of charging liquid in a sealing mode, and particularly relates to a filling, storing and charging device and a charging method of ultrapure cooling liquid of a water-cooled frequency converter. According to the filling, storing and charging device and the charging method, a gas path pipe is connected with a second two-way air valve so as to be arranged on the top of a pressure bearing container liquid tank, a liquid path pipe is connected with a two-way liquid valve so as to pass through the top of the pressure bearing container liquid tank to the bottom, the other end of the two-way liquid valve is connected with a liquid path flowmeter, quick change connection are formed on both ends of the liquid path flowmeter, the pressure bearing container liquid tank is made of pressure resistant stainless steel materials, the pressure bearing container liquid tank is integrally sealed, and a safety relief valve is installed on the top of the pressure bearing container liquid tank. The device is sealed in a charging process, so that safety accidents caused by charged elements in a high-voltage environment are avoided; additionally, the charging process is carried out in a sealing state, so that the cooling liquid does not make contact with air, and the quality of the cooling liquid is not changed.

Description

technical field [0001] The invention relates to the field of sealed liquid filling, in particular to a water-cooled frequency converter ultra-pure coolant filling storage filling device and filling method. Background technique [0002] The high-voltage inverter generates a lot of heat during use, and needs to be cooled by cooling liquid circulation. The cooling liquid is lost during the process and often needs to be replenished. The coolant in the prior art is filled manually, which has the following problems: [0003] 1. When filling, you need to open the coolant container. Once the container is opened, the coolant will come into contact with the air, which will deteriorate the effective components in the coolant, reduce the resistance and insulation of the coolant, and degrade the quality of the coolant or even make it unusable and scrapped. , the consumption cost of production consumables increases; [0004] 2. The high-voltage frequency converter is in a high-pressure ...

AI Technical Summary

Problems solved by technology

[0003] 1. When filling, you need to open the coolant container. Once the container is opened, the coolant will come into contact with the air, which will deteriorate the effective components in the coolant, reduce the resistance and insulation of the coolant, and degrade the quality of the coolant or even make it unusable and scrapped. , the consumption cost of production consumables increases;

[0004] 2. The high-voltage frequency converter is in a high-pressure environment, and the existing manual filling, whether it is pumped with a bucket pump or manually poured out of a small container for sub-package and transfer, has poor safety and high labor intensity;

[0005] 3. The existing packaging container is 200L or 1000L, the packaging is too large, not only it is inconvenient to move during storage and use, but also once the coolant deteriorates, it cannot be used, causing a lot of waste (coolant is expensive);

[0006] 4. The container cannot be recycled and reused, and needs special disposal

However, this patent also has technical problems such as the conductivity of the medium and the inability to ensure that the cooling water will not be polluted by the air. It is not suitable for liquid filling in special industries such as high-voltage inverters.
