Siemens Resin Cast (Dry) Switch Transformer
Since 1965, Siemens resin cast transformers have been successfully operated. More than 80,000 Siemens resin cast transformers worldwide have proven their quality through safe operation in power distribution or rectification systems.
High voltage winding
The high-voltage winding is made of aluminum foil and high-quality insulating foil. The wire cake is placed in a heating mold and poured with a specially formulated resin in a vacuum tank. Vacuum casting evacuates the gas in the winding to ensure low partial discharge of the transformer. Because the thermal expansion coefficients of aluminum foil and cast resin are very similar, the thermal stress caused by load changes is kept to a minimum to improve the crack resistance of the winding.
Foil windings combine simple technology with a high degree of electrical safety. Compared with other types of windings, insulation withstands less electrical stress. In traditional round wire windings, the inter-turn voltage can reach twice the inter-layer voltage. One layer of the foil winding has only one turn, so the electrical stress remains constant, and the winding can withstand high power frequency voltage and impulse voltage.
Low voltage winding
The dielectric stress of the low-voltage winding is very small. This kind of winding is made of a single piece of aluminum foil or copper foil and insulated with resin impregnated glass fiber cloth in the middle.
Use flame retardant and self-extinguishing materials, no additional materials. Internal arcs and external fires caused by electrical faults will not cause the transformer to explode or burn. After extinguishing the fire source, the transformer will self-extinguish. This design structure has been approved by fire protection agencies in many countries and can be used in residential buildings and other types of buildings. After several tests, it has been proved that the burning residue of the transformer is not harmful to the environment.
Resin cast dry-type transformers meet the highest protection level requirements currently stipulated:
Environment class E2
Climate class C2
Fire rating F1
After installing the radial cooling fan, the transformer can be permanently overloaded by 50%. As long as the maximum temperature of the coil is not exceeded within the overload time, short-term overload is negligible.
Each transformer is equipped with a temperature indicator, and three temperature sensors are installed in the low-voltage winding. The temperature indicator can output fault, alarm and trip signals to protect the transformer. The sensor is used to detect the maximum temperature of the winding.
Shandong shun kai electrical equipment co., LTD. Was established in April 2014, the registered capital of 50 million yuan, mainly engaged in electrical equipment manufacturing, sales, mechanical and electrical equipment installation and sales, etc., is a collection of r &d, manufacturing, sales, service as one of the at the same time with perfect design and production capacity of the industrialization of the integrated high-tech enterprises.
It has modern workshop, advanced automatic production line, perfect product quality testing system and a series of advanced test equipment.
Under the production, technology, quality inspection, sales, service and other departments, there are 157 employees, including 26 engineers and 5 senior engineers.
Since its establishment two years ago, the company has begun to take shape. It has established a complete sales and service system in shandong province and even in the whole country. Its business has expanded rapidly and it has shown its influence in the industry.
In the process of equipment manufacturing and sales, the company adheres to the enterprise service concept of "quality first, customer first, technology leading, truth-seeking and innovation". With high-quality products, good corporate reputation, affordable product price and prompt and thoughtful after-sales service, the company has quickly won the praise of users and gradually established a good brand image.
Give full play to industrial advantages, take the road of diversified, brand, group development
Technology is the key to the development of enterprises, and the group development is the only way for enterprises.
The company takes technology, equipment, site and talents as its advantages, and closely links r&d, procurement, manufacturing, sales and management, so as to form a "triangle" enterprise group development model through coordinated operation, cost reduction and complementary advantages.
Take the road of technological development, drive enterprises with technological advantages, promote technological development with enterprise foundation, and form new technology-oriented enterprise groups.
A coordinated and integrated group development model of production, supply and marketing has been basically formed, and the scale effect of collectivized operation has initially emerged, laying a solid foundation for sustainable development in the future.
