Weighing-type transformer oil conservator

Abstract

The invention provides a weighing-type transformer oil conservator, which is technically characterized in that four supports are arranged between a transformer oil conservator and a transformer oil tank, four four-bar hinge mechanisms are arranged at the middle parts of the supports, and four weighing sensors in two groups or two weighing sensors in a group are respectively connected into the four four-bar hinge mechanisms; and digital oil level gages for displaying oil weight are installed at the two ends of the transformer oil conservator. The weighing-type transformer oil conservator has the advantages that since four pressure sensors in two groups are arranged in hinges to weigh the oil conservator at the upper part of the sensors and the quantity of oil in the oil conservator, the accurate quantity of the oil in the oil conservator is determined, the digital display of the quantity of the oil in the oil conservator is realized and the long-term stable operation of a transformer and the oil conservator is ensured; and since a solar panel and a battery power supply are installed on the transformer oil conservator, the weighing-type transformer oil conservator is especially suitable for oil-cooled large-size and medium-size transformers.

Description

Technical field [0001] The present invention involves a large and medium -sized oil immersion transformer, especially a weighed transformer oil storage cabinet. Background technique [0002] At present, the inside of the oil storage cabinet of large and medium -sized oil immersion transformers is a stainless steel swelling method, a capsule method, a diaphragm method, and so on.In order to display the oil volume in the oil storage cabinet, it is mostly transmitted to various fuel levels to display the oil level by mechanical swing rods, zippers, etc. The technical problems are: 1. Mechanical swing rods, zippers and other institutions are prone to failure.Make the oil level instruction errors and cause an accident.2. Internal swelling, capsules, and diaphragm Once the error runs, the fuel level will be mistakenly indicated. Invention content [0003] The purpose of the present invention is to provide a weighing transformer oil storage cabinet for the shortcomings in the above tec...

Problems solved by technology

In order to display the amount of oil in the oil conservator, various oil level gauges are used to display the oil level through mechanical swing rods and zippers. The technical problems are: 1. Mechanisms such as mechanical swing rods and zippers are prone to failure. Make the oil level gauge indication wrong, causing accidents

2. Once the internal expansion and contraction joints, capsules, and diaphragms operate incorrectly, the oil level gauge will give false indications
