Description

Oil-immersed transformer structure

Technical Field

The invention mainly relates to the technical field of transformer structures, in particular to an oil-immersed transformer structure.

Background

The transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and main components are a primary coil (4), a secondary coil (4) and an iron core (magnetic core). The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, and the like. According to the application, the method can be divided into: power transformers and special transformers. The circuit symbols are usually T as the beginning of the numbering, e.g., T01, T201, etc. Oil-immersed transformer is generally multi-purpose in the open air, long-time the erosion that receives rainwater and air, transformer tank's surface can be because the damaged phenomenon of rusty production, on the one hand when transformer tank damage is serious, transformer oil flows out very fast, make lack insulating medium between the component in the transformer, danger can take place, the convenient damaged department of transformer tank of another party is less, the staff is difficult to the discovery, the damaged department of transformer is not convenient for staff's the searching simultaneously, it is not handled for a long time, also can make transformer oil flow to the greatest extent, make the transformer take place danger.

Disclosure of Invention

The invention mainly provides an oil-immersed transformer structure which is used for solving the technical problems in the background technology.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides an oil-immersed transformer structure, includes oil tank box and transformer body, the transformer body sets up in the oil tank box, the oil tank box comprises bottom plate, curb plate and apron, the curb plate is sealed fixed with bottom plate, apron respectively, the curb plate encloses into one and holds the chamber, be fixed with the reflector panel on the curb plate outer wall, fixedly connected with air cushion between reflector panel and the curb plate, be fixed with the fin on the curb plate, just be located to be equipped with the mounting groove between two adjacent fins on the curb plate, be equipped with white easily-dyed piece in the mounting groove, oil tank box lower extreme is fixed with the base, be equipped with pressure sensor in the base, the base lower extreme is fixed with the supporting leg.

Further, the oil tank body is made of stainless steel or alloy steel.

Further, the reflector is obliquely arranged.

Furthermore, more than two mounting grooves are formed between every two adjacent cooling fins.

Further, the white easy-dyeing piece is white high-temperature-resistant fabric.

Further, still include controller and alarm, the controller respectively with alarm and pressure sensor electric connection.

Compared with the prior art, the invention has the beneficial effects that:

the oil tank is provided with the pressure sensor, when the pressure sensor senses that the weight change of oil in the oil tank body is abnormal, a signal can be sent to the controller in time, the controller can command the alarm to work, so that a worker can process the oil as soon as possible, and after the oil leaks, the oil can firstly pollute a white easily-dyed piece nearby the oil, so that the worker can find the leaking position as soon as possible.
