The SCBH15 amorphous alloy dry - type transformer features an ultra - low loss design, excellent noise reduction performance, high - temperature resistance, and good harmonic resistance ability.

The KBSG Mine Flameproof Dry Type Transformer, a masterpiece developed by Jiangsu Yawei, stands as a beacon of reliability and safety in the challenging realm of coal mine power distribution. Engineered with meticulous attention to detail and a deep understanding of the unique demands of mining environments, this transformer is a crucial asset for ensuring the seamless operation of comprehensive mechanized mining equipment amidst the presence of methane mixed gas, coal dust, and potential explosion hazards.
In the harsh and unforgiving conditions of coal mines, a stable and secure power supply is the lifeblood of mining operations. The KBSG Mine Flameproof Dry Type Transformer rises to this challenge with its exceptional capabilities. It serves as the vital link that powers a diverse array of mining machinery, enabling the efficient extraction and processing of coal. Without a reliable source of electricity, the entire mining process would grind to a halt, making this transformer an indispensable component in the mining ecosystem.
One of the most remarkable features of this transformer is its outstanding adaptability to challenging environmental conditions. It is designed to operate continuously for extended durations under specific service conditions that mimic the rigors of coal mine environments. With an altitude limit of no more than 2000m, it can be deployed in a wide variety of mining locations across different terrains. The ability to withstand an ambient temperature of up to +40℃ and a relative air humidity of not exceeding 95% (at +25℃) showcases its resilience in harsh climates. Moreover, its resistance to strong turbulence, vibration, and a vertical plane inclination of no more than 15 degrees makes it a reliable choice for the dynamic and rugged conditions typically found in coal mines. This adaptability ensures that the transformer can maintain its performance and functionality, even in the most adverse circumstances.
The structure of the KBSG Mine Flameproof Dry Type Transformer is a testament to its durability and safety. The box shell, ingeniously designed as an explosion-proof structure with a top open cover, provides a robust shield against potential explosions, safeguarding the internal components and the surrounding environment. The use of corrugated steel plates on the sides and thick steel plates at the bottom not only enhances its structural strength but also contributes to its overall sturdiness. The high and low voltage sides are equipped with connecting flanges, facilitating easy and secure connection to the electrical system, ensuring a stable power transfer. The hoisting mixers on the box cover and shell offer convenience during installation and maintenance, allowing for effortless handling of the transformer. The grounding bolts and marks are essential safety features that ensure proper grounding, minimizing the risk of electrical accidents and enhancing the safety of the mining operation.
The core assembly of the transformer is a result of careful engineering and material selection. The utilization of high-quality cold-rolled oriented silicon steel sheets in a multi-stage stepping full-slope three-seam amination structure is a strategic choice that significantly reduces no-load loss and no-load current, thereby improving the energy efficiency of the transformer. The application of high-temperature anti-rust and moisture-proof paint not only protects the core from corrosion but also safeguards it from degradation caused by environmental factors, ensuring its long-term reliability. The clamp, constructed from channel steel with a pull screw structure for tensioning, effectively prevents relative displacement between the core and the clamp, maintaining the integrity and quality of the product.
The insulation assembly of the KBSG Mine Flameproof Dry Type Transformer is a critical component that ensures electrical safety and performance. The main longitudinal insulation, made from top-notch insulating materials, provides an effective barrier against electrical leakage, ensuring the proper functioning of the transformer. The tight winding technology employed for the high and low voltage coils not only enhances their mechanical strength but also contributes to their electrical stability. The use of C-grade insulating paper wrapped around oxygen-free copper conductors creates a uniform electric field, reducing the risk of partial discharge and ensuring a reliable electrical connection. The careful arrangement of coil pressing with pressing nails and porcelain pressing blocks prevents looseness, guaranteeing stable operation even under varying load conditions.
The design of the high and low voltage leads is another aspect that emphasizes safety. The cable-led high-voltage lead and the option of using either a cable or copper bus for the low-voltage lead ensure a proper and secure electrical connection. With creepage distances and air gaps that exceed the relevant provisions in GB3836.3-2000, the risk of electrical breakdown and the occurrence of sparks, arcs, or dangerous temperatures is significantly reduced, ensuring the safe and reliable operation of the transformer.
The trolley, fixed at the bottom of the box with bolts and featuring a gauge of 900/600mm, adds to the versatility of the transformer. It provides mobility, allowing for easy installation and relocation as per the requirements of different mining scenarios. The ability to disassemble the trolley as needed further enhances the flexibility of using the transformer in various settings.
In conclusion, the KBSG Mine Flameproof Dry Type Transformer from Jiangsu Yawei is a cutting-edge power distribution solution that combines advanced technology, robust construction, and stringent safety standards. Its ability to operate in harsh environments, its durable structure, and its reliable performance make it an essential component for ensuring the smooth and secure operation of coal mine activities, contributing significantly to the efficiency and safety of the mining industry.
