Full-automatic oil-pumping liquid adding and draining device

Abstract

The invention discloses a full-automatic oil-pumping liquid adding and draining device. The full-automatic oil-pumping liquid adding and draining device comprises a tank body, an electrolyte bottle and a waste liquid bottle which are arranged side by side on the tank body, a liquid adding and draining opening, an oil draining opening, a liquid adding opening, a draining opening B, a waste oil liquid opening and a draining opening A which are sequentially arrayed on the tank body and a titration cell which is communicated with the liquid adding and draining opening through a distribution pipe, wherein the electrolyte bottle is separately communicated with the liquid adding opening and the draining opening B through a distribution pipe; the waste liquid bottle is separately communicated with the draining opening A and the waste oil liquid opening through a distribution pipe; and the titration cell is communicated with the oil draining opening through a distribution pipe. By adopting the full-automatic oil-pumping liquid adding and draining device disclosed by the invention, oil draining, electrolyte adding and electrolyte draining can be realized manually or automatically; tedious steps of changing electrolyte manually in the prior art are omitted; and experiment personnel are protected from damage of harmful gas. Therefore, new electrolyte changing and waste electrolyte draining can be realized by an operator without touching the electrolyte; the operator is protected from damage of chemical agents and gas; and environment pollution is avoided.

Description

technical field [0001] The invention relates to a fully automatic oil pumping and draining device, which is used in a transformer oil micro-water tester. Background technique [0002] The transformer oil micro-water tester is a set of relatively sophisticated analytical instruments, and specific chemical reagents need to be added during use. If the operation is not careful, it will not only affect the test effect of the test instrument, but also affect the health of the operator. [0003] The transformer oil micro-water tester injects the oil sample into the electrolyte, and electrolyzes the water in the oil by applying a voltage drop. The amount of water in the oil is proportional to the amount of electricity, and the water content in the oil is calculated through the electrolysis of electricity. After a certain number of tests, the amount of oil in the electrolyte increases, and the oil needs to be removed; the efficiency of the electrolyte decreases, and the electrolyte n...

AI Technical Summary

Problems solved by technology

After a certain number of tests, the amount of oil in the electrolyte increases, and the oil needs to be removed; the efficiency of the electrolyte decreases, and the electrolyte needs to be replaced

However, the electrolyte contains sulfur dioxide, which is very harmful to the body. The traditional method of draining oil and replacing the electrolyte inevitably exposes the electrolyte to the air. Even if the replacement time is shortened as much as possible, it will inevitably affect the The content of the components, and it is very harmful to the human body
