transformers can be divided into dry-type transformers and oil immersed transformers

for the convenience of heat dissipation of oil immersed transformer, that is, for the flow and heat dissipation of internal insulating oil, a radiator is designed outside, just like a heat sink, while the dry-type transformer does not have this radiator. The heat dissipation depends on the fan under the transformer coil, which is a bit like the indoor unit of household air conditioner; Due to the need of fire prevention, oil immersed transformers are generally installed indoors or outdoors, while dry-type transformers must be installed indoors. Generally, they are installed in the low-voltage distribution room side by side with the low-voltage distribution cabinet. According to different manufacturing processes, dry-type transformers can be mainly divided into two types: impregnated type and epoxy resin type. Among them, epoxy resin type is also divided into epoxy resin pouring type and epoxy resin wrapping type

at present, there are still many oil immersed transformers in terms of consumption. However, due to the environmental protection, flame retardancy, impact resistance and other advantages of dry transformation, it is often used in indoor power supply and distribution stations with high requirements, such as hotels, office buildings, high-rise buildings and so on. If you are just a transformer user, it should be enough to understand these. Each has its own advantages and disadvantages. The oil transformer has low cost and convenient maintenance, but it is flammable and explosive. Due to its good fire resistance, the dry transformer can be installed in the load center area to reduce voltage loss and power loss. However, the dry transformer is expensive, large in size, poor in moisture and dust resistance, and noisy. The oil transformer is gradually withdrawn, and the dry transformer is used. The dry transformer can be disassembled for transportation and defecation, which is clean and easy to maintain. The machine base is not required for installation, and there is no oil seepage pool 3. The capacity and voltage are different. Dry type transformers are generally suitable for power distribution. Most of them have a capacity of less than 1600KVA and a voltage of less than 10kV, and some of them have a voltage level of 35kV; But the oil transformer can achieve all the capacity from small to large, and the voltage level can also achieve all the voltages; The UHV 1000kV test line under construction in China must be oil type transformer. 4. Insulation and heat dissipation are different. Dry type transformers are generally insulated with resin, which is cooled by natural air, and large capacity is cooled by fans. Oil type transformers are insulated by insulating oil, which circulates inside the transformer to transfer the heat produced by the coil to the radiator (fin) of the transformer for heat dissipation. 5. Applicable places: dry-type transformers are mostly used in places where the size of the experimental operation space and the size of the rack depend on the size. They are generally easy to be used in large-scale buildings and high-rise buildings; Oil type transformers, which may cause fires due to oil spray or leakage after accidents, are mostly used outdoors, and there are places where accident oil pools are dug. 6. The load bearing capacity is different. Generally, dry-type transformers should operate under the rated capacity, while oil type transformers have better overload capacity. 7. The cost is different. For transformers with the same capacity, the purchase price of dry-type transformers is much higher than that of oil transformers

transformers are easy to distinguish from each other in appearance; The biggest difference between oil immersed transformer and dry-type transformer is whether there is oil. Because oil is liquid and has fluidity, oil immersed transformer must have a shell. The inside of the shell is transformer oil, and the coil of the transformer is soaked in the oil, and the coil of the transformer cannot be seen from the outside; The dry-type transformer has no oil, so the shell is not needed, and the coil of the transformer can be seen directly; Another feature is that there is an oil conservator on the oil immersed transformer, and the transformer oil is stored inside, but now the new oil immersed transformer is also produced without an oil conservator; For the convenience of heat dissipation, the oil immersed transformer will make some simple changes. The steps are to facilitate the flow and heat dissipation of internal insulating oil. The radiator is designed outside, just like the heat sink, while the dry-type transformer does not have this radiator. The heat dissipation depends on the fan under the transformer coil, which is a little like the indoor unit of household air conditioner; Due to the need of fire prevention, oil immersed transformers are generally installed indoors or outdoors, while dry-type transformers must be installed indoors. Generally, they are installed in the low-voltage distribution room side by side with the low-voltage distribution cabinet

low voltage complete sets of equipment are widely used in power plant low-voltage system power distribution, electrical transmission and automatic control equipment. As we all know, power generation itself consumes a lot of energy. According to statistics, the power consumption of low-voltage electrical appliances accounts for more than half of the total energy consumption of power plants. In recent years, with the large and low-voltage complete sets of equipment widely used in power plant low-voltage system distribution, electrical transmission and automatic control equipment. As we all know, power generation itself consumes a lot of energy. According to statistics, the power consumption of low-voltage electrical appliances accounts for more than half of the total energy consumption of power plants

canceling the corresponding output is to interrupt the hammer positioning transformer, which is easy to distinguish from the outside; The biggest difference between oil immersed transformer and dry-type transformer is whether there is oil.

transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). However, according to a deputy chief engineer of Beijing New Building Materials Co., Ltd
