High Vacuum Oil Purifier & Transformer Dry-out System
Model BA-HV Series
Purification of Electrical Insulating Liquids
Today's electrical equipment requires the need for a high degree of insulating fluid purification. Such requirements call for the removal of moisture, gases, solid particulate matter and traces of chemical contamination from the insulating fluid.
Moisture content is recognized as one of the main causes of variation in the electrical properties of insulating materials, both from a chemical and physical point of view. Even in small amounts, moisture can accelerate the aging process.
It is important to start initially at the factory with a dry insulation system and pure, dry and degasified dielectric liquid during transformer impregnation and the qualification tests.
Later, the same care must be taken during installation in the field and after every maintenance check, requiring exposure of the insulating system to the environment.
The BA process, developed by Baron USA, upgrades new insulating liquids and reclaims used dielectric oils through filtration, vacuum dehydration, degasification and clay treatment (when necessary).
BA Systems include filters with a 0.5-1.0 micron nominal filtration rating for the removal of particulate. If excessive free water is present in oil, a Baron type VCS free water trap is used prior to vacuum dehydration. The BA High Vacuum Process then removes dissolved water, free and absorbed air and other gases.
BA Fuller's Earth Filters provide corrective treatment for removal of the products of oxidation, dissolved varnish and gums and other traces of chemical contaminants.
BA Systems with High Vacuum Pumps provide fast and complete transformer dry-out and fill with clean, dry and hot oil under vacuum conditions.
BA Interstage Oil Condensers provide a continuous system for removal of light-end oils for vacuum system protection during transformer dry-out processes.
A compact Programmable Logic Controller (PLC) and an Operator Interface Terminal (OIT) are supplied to allow ease of operation and a clean installation.
Operation of the system is as simple as pressing one single key on the OIT.
The system undergoes a controlled startup fully automatically. The OIT gives a display of the description of any alarm with the time and date of occurrence. In the event of an abnormal condition, the PLC attempts to correct the problem automatically. If the condition does not self-correct, the PLC executes a controlled shutdown of the equipment and alerts the operator of the problem. Manual shutdown is also a single-button function. Manual overrides are available on the OIT for the purpose of troubleshooting or final draining of the unit for transport or maintenance.
Baron Purifiers utilize rotary tri-screw pumps, which give you a long field life. The pumps are direct-driven so that belts, pulleys or gear reducers are not required. The purifier is constructed with butt-welded fittings installed by certified welders wherever possible. This minimizes oil leakage, which is especially important on portable equipment.
Baron uses low watt-density aluminum finned-tube heaters that are sand-packed to provide excellent heat transfer and provide full element support. This is essential for long heater life in mobile equipment. We also use only full flow hydraulic relief valves and do not use the pop-off type that can subject the system to hydraulic shock, reducing component life and causing leakage.
Baron systems are designed with the operator in mind. They are designed for ease of use and require only minimal monitoring when in operation. Maintenance for all Baron purifiers is simple, and we use only superior quality components for their design. In fact, we maintain a supply of commonly used replacement parts and can ship worldwide to meet our customer's needs. Our friendly and knowledgeable staff can handle calls for assistance, and can also provide on-site assistance in troubleshooting or for operator training.
Our systems employ internally bypassed vacuum booster pumps so that the booster can be started at atmosphere with the backing pump. This eliminates the need for unreliable vacuum switches for starting and helps reduce apparatus evacuation time.
