Description

technical field [0001] The invention relates to the technical field of transformer devices, in particular to a skid-mounted transformer device. Background technique [0002] The power transformer is one of the main equipments of power plants and substations. The function of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. In short, both step-up and step-down must be completed by transformers. In the process of transmitting electric energy in the power system, two parts of voltage and power will inevitably be lost. When the same power is transmitted, the voltage loss is inversely proportional to the voltage, and the power loss It is inversely proportional to the square of the voltage. The transformer is used to increase the voltage and reduce the power transmission loss. The transformer is composed of...

[0002] The power transformer is one of the main equipments of power plants and substations. The function of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. In short, both step-up and step-down must be completed by transformers. In the process of transmitting electric energy in the power system, two parts of voltage and power will inevitably be lost. When the same power is transmitted, the voltage loss is inversely proportional to the voltage, and the power loss It is inversely proportional to the square of the voltage. The transformer is used to increase the voltage and reduce the power transmission loss. The transformer is composed of two or more coil windings wound on 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 position of the transformer should be considered to be convenient for operation, maintenance and transportation. At the same time, a safe and reliable place should be selected. When using the transformer, the rated capacity of the transformer must be selected reasonably. These reactive powers must be supplied by the power supply system. If the capacity of the transformer is too large, it will not only increase the initial investment, but also make the transformer run at no-load or light-load for a long time, which will increase the proportion of no-load loss. The power factor decreases and the network loss increases, so the operation is neither economical nor reasonable

If the transformer capacity is too small, the transformer will be overloaded for a long time and the equipment will be easily damaged. Therefore, the rated capacity of the transformer should be selected according to the needs of the power load, and it should not be too large or too small;

[0003] At present, the skid-mounted power transformers used in various power system substations in metallurgy, petroleum, chemical industry, coal, steel, electric power and other industries are mostly placed in the outdoor open-air environment, with poor protection effect, and the transformer device does not have shock absorption in bad weather. function, device replacement, and transfer, the internal parts are likely to interfere with each other, and the existing device is greatly affected by the harsh outdoor environment. The temperature is too high and cannot be evacuated, resulting in damage to the device, heavy maintenance and repair workload, high failure rate of transformer operation, relatively fast aging speed of insulating oil, and relatively short service life of transformer. Most of the existing devices are fixed and disassembled It is inconvenient, prolongs the replacement time, and affects the normal operation of the lower-level power distribution equipment
