Automatic water supplementing device for water-air cooler of rectifier cabinet

Abstract

The invention relates to an automatic water supplementing device, in particular to an automatic-control water supplementing device for the water-air cooler of a rectifier cabinet. The automatic water supplementing device comprises the water-air cooler which is connected with a water supplying pipeline through an electric controllable valve; the water supplying pipeline is connected with a water tank; and the electric controllable valve is connected with an automatic control box. The automatic water supplementing device has the beneficial effects that: according to the automatic water supplementing device disclosed by the invention, the problem that rectifier elements in the rectifier cabinet are overheat to trip because the water-air cooler cannot normally work due to water insufficiency in the water-air cooler is solved; the problems that the manual water supplementation is not timely and requires high labor intensity are also solved; the power supply reliability of an electrolytic series is improved; the requirement of safe continuous production of the electrolytic series is met; and the labor intensity of operators is also reduced.

Description

technical field [0001] The invention relates to an automatic water supply device, in particular to an automatically controlled automatic water supply device for a water-air cooler of a rectifier cabinet. Background technique [0002] The cooling of the rectifier components of the rectifier cabinet in the electrolytic aluminum plant basically adopts water cooling. With the increase of the rectified voltage and the increase of the electrolysis current, the requirements for the cooling water system are getting higher and higher. In addition to the requirements for water pressure, water temperature and flow rate, the requirements for the quality of water supply are also more stringent. Due to the large current, large power loss, and large heat generation of high-current silicon rectifiers, cooling is a very important issue. Water-air cooling is commonly used in high-current silicon rectifiers for electrolysis. During the working process, part of the water is lost by evaporatio...

AI Technical Summary

Problems solved by technology

The existing water-air cooler does not have the function of automatic replenishment of water. During operation, regular manual replenishment of water is required, which is labor-intensive

If the water is not replenished in time, the water-air cooler cannot work normally due to lack of water, which will directly cause the rectifier components in the rectifier cabinet to overheat and trip, affecting the normal production of the electrolytic series
