Overview

Oil immersed series distribution transformers have the characteristics of low loss, low noise, and high efficiency, which can achieve good energy-saving effects and reduce pollution. Compared with ordinary oil immersed transformers, fully sealed transformers eliminate oil storage tanks, and the change in oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheets in the corrugated oil tank. The transformer is isolated from air to prevent and slow down oil degradation and insulation aging, enhance operational reliability, and achieve normal operation without maintenance.

Product Details

Oil immersed series distribution transformerThe components include the body (iron core, winding, insulation, leads), transformer oil, oil tank and cooling device, pressure regulating device, protective device (moisture absorber, safety airway, etc.)gas relayOil storage tanks and temperature measuring devices, as well as outlet sleeves. Specific composition and functions(1) Iron coreThe iron core is the main magnetic circuit part in transformers. It is usually made by stacking hot-rolled or cold-rolled silicon steel sheets with high silicon content, thicknesses of 0.35mm, 0.3mm, and 0.27mm, and coated with insulating paint on the surface. The iron core is divided into two parts: the iron core column and the transverse piece. The iron core column is covered with windings; Horizontal plates are used for closed magnetic circuits.

(2) WindingThe winding is the circuit part of a transformer, which is wound with double insulated flat wire or enameled round wire. The basic principle of a transformer is the principle of electromagnetic induction. Taking a single-phase double winding transformer as an example, its basic working principle is explained: when a voltage U1 is applied to the primary winding, a current I1 flows through it, and an alternating magnetic flux O1 is generated in the iron core. These magnetic fluxes are called the main magnetic flux. Under its action, the two windings induce electric potential respectively, and finally drive the transformer control device.

Power transformers are one of the main equipment in power plants and substations. The function of a transformer is multifaceted, not only can it increase the voltage to deliver electrical energy to the electricity consuming area, but it can also reduce the voltage to various levels of usage voltage to meet the needs of electricity consumption. In short, both voltage boosting and voltage lowering must be accomplished by transformers. In the process of transmitting electrical energy in the power system, there will inevitably be two parts of loss: voltage and power. When transmitting the same power, voltage loss is inversely proportional to voltage, and power loss is inversely proportional to the square of voltage. utilizetransformerIncreasing voltage reduces power transmission losses.

Oil immersed series distribution transformerIt is composed of two or more coil windings wound around the same iron core, and the windings are connected by an alternating magnetic field and work according to the principle of electromagnetic induction. The installation location of transformers should be considered for ease of operation, maintenance, and transportation, and a safe and reliable place should be selected. The rated capacity of the transformer must be selected reasonably when using it. When the transformer operates without load, a large amount of reactive power is required. These reactive powers need to be supplied by the power supply system. If the capacity of the transformer is chosen to be too large, it not only increases the initial investment, but also causes the transformer to operate under no-load or light load for a long time, resulting in an increase in the proportion of no-load losses, a decrease in power factor, and an increase in network losses. Such operation is neither economical nor reasonable. Choosing a transformer capacity that is too small can cause long-term overload of the transformer and easily damage the equipment. Therefore, the rated capacity of the transformer should be selected according to the needs of the electrical load, and should not be too large or too small.
