Electrical Transformer
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.
Structural Features
- It is safe, fireproof, pollution-free, and can run directly in the load center.
- Using domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.
- Low loss, low noise, obvious energy saving effect, and maintenance-free.
- Good heat dissipation performance, strong overload capacity, and capacity operation can be increased when forced air cooling.
- Good moisture-proof performance, adapt to high humidity and other harsh environments.
- Dry-type transformers can be equipped with a complete temperature detection and protection system. Adopt intelligent signal temperature control system. It can automatically detect and cyclically display the respective operating temperatures of the three-phase windings.
- Small size, light weight, less space and low installation cost.
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.
Structural Features
- It is used in conjunction with fiber materials, and its insulation performance is good, which can reduce the insulation distance and reduce the cost.
- Transformer oil has low viscosity and good heat transfer performance.
- It can well protect the core and windings to avoid being affected by moisture in the air.
- Protect insulating paper and insulating cardboard from the action of oxygen, reduce the aging of insulating materials, and extend the life of the transformer.
- Except for some special-purpose small and medium-sized transformers and gas transformers, most large and medium-sized transformers still use transformer oil as a cooling and insulating 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.
Structural Features
- Safe, non-flammable, and fireproof can be installed directly in the load center.
- Maintenance-free, easy to install, economical and low operating cost.
- Good moisture resistance, can operate normally under 100% humidity.
- Low loss, good insulation, small partial discharge, no pollution, and the loss is usually about 75% lower than that of a traditional transformer.
- Good heat dissipation, strong overload capacity, 50% overload capacity under air-cooled conditions.
- Reliable operation, with a complete temperature protection control system, which can ensure the safe operation of the transformer.
- Small size, light weight, stable structure, strong lightning resistance and high mechanical strength
- Strong resistance to temperature changes and sudden short circuit.
- There is no need to change the oil under normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life.
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.
