Electrical transformer is a static electrical device. That is used to convert a certain value of AC voltage (current) into another or several voltages (current) of the same frequency with different values. ZMS electrical transformer company produces and wholesales a wide range of cable accessories (electrical transformer products).
Electrical Transformer Product Typs
Products include: dry-type transformers, 10kV, 20kV, 35kV oil-immersed power transformers, energy-saving power transformers, special transformers, amorphous alloy transformers, box-type substations, combined substations, complete sets of high and low voltage power transmission and distribution equipment, etc.
Electrical Transformer Product Typs
The dry-type transformer simply refers to a transformer in which the core and windings are not immersed in insulating oil.
Dry Type Transformer
It is mainly composed of an iron core composed of silicon steel sheets and a coil casted with epoxy resin. An insulating tube is placed between the high and low voltage coils to increase electrical insulation, and the coils are supported and constrained by spacer blocks. The fasteners that overlap the parts have anti-loosening properties. This product is widely used in local lighting, high-rise buildings, airports, terminal CNC machinery equipment and other places.
Distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings.
Oil Immersed Transformer
It reduces the 10(6)kV or 35kV network voltage to the 230/400V bus voltage used by the user. Transformer oil is a petroleum-based liquid, which has the possibility of burning and has disadvantages in environmental protection. But because transformer oil has the characteristics of excellent performance and low price. Most electrical transformers still use transformer oil as insulation and cooling medium.
Amorphous alloy transformer is a low-loss, high-energy-efficiency power transformer with iron-based amorphous metal as the core.
Sealed Amorphous Alloy Power Transformer
The no-load loss of amorphous alloy transformers is 70-80% lower than that of traditional transformers that generally use silicon steel as the core. It is a very ideal low-loss energy-saving transformer at present. Due to the low loss, the amorphous alloy transformer has less heat, low temperature rise, and very stable operating performance. It can be widely used in high-rise buildings, subways, machinery, industrial and mining, mining, petroleum, etc. It is especially suitable for use in places with high anti-inflammatory requirements and harsh environments such as flammable and explosive.
About the Role of Electrical Transformers
ZMS manufacturer transformer is a static electrical equipment used to transform AC voltage and current to transmit AC power. It realizes electric energy transfer based on the principle of electromagnetic induction. Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multi-faceted not only to increase the voltage to send electrical energy to the electricity-consuming area, but also to reduce the voltage to the voltage used at all levels to meet the needs of electricity. In short, both step-up and step-down must be completed by a transformer. 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 delivered, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. The transformer is used to increase the voltage, and the power transmission loss is reduced.
The transformer is composed of two or more coil windings wound on the same iron core. The windings are connected by an alternating magnetic field and work according to the principle of electromagnetic induction. The location of the transformer installation should be considered for ease of operation, maintenance and transportation, and a safe and reliable place should be selected. When using a transformer, the rated capacity of the transformer must be selected reasonably. When the transformer is running at no load, a larger reactive power is required. These reactive power must be supplied by the power supply system. If the transformer capacity is selected too large, it will not only increase the initial investment, but also keep the transformer in no-load or light-load operation for a long time, which will increase the proportion of no-load loss, reduce the power factor, and increase the network loss. This operation is neither economical nor uneconomical. 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 electrical load, and should not be too large or too small.
