Recently, varelen Easy to independently developed a mine flameproof dry transformer with active heating pipe, the company's full wave mining explosionproof dry type transformer products were upgraded again, creating a new era of flameproof heat dissipation. Varelen Electric enables product innovation with science and technology, helps the industry technology climb the peak, and promotes new changes in the flameproof transformer industry.
Innovation and upgrading to new heights
On the basis of the company's second generation patent bellow shell, KBSG series of mine flast-proof dry transformer innovatively adopts an active heat dissipation tube and a zonal efficient heat dissipation design, which improves the heat dissipation performance of the transformer, delays the aging speed of insulating materials, and enhances the reliability and stability of the product. Power flameproof changes in the heat dissipation capacity, insulation capacity, safety and reliability performance to a higher level.
Core advantage Performance increases dimension
Improve heat dissipation and prolong service life
Through the design concept of zoning heat dissipation, the top of the box adopts a curved corrugated plate, and the side is a rectangular corrugated component with an active heating pipe. The outside of the active heat pipe is the high-temperature gas in the box, and the inside is the external circulating air, which greatly improves the heat exchange area of the inner and outer air. There is a high temperature difference between the upper and lower parts of the heat dissipation pipe, which forms an active convection heat dissipation based on the aerodynamic principle and improves the heat dissipation efficiency. Based on the above unique innovative heat dissipation structure, the temperature rise of the internal transformer can be effectively reduced, delaying the aging of the transformer core insulation, and effectively improving the service life of the product.
Top curved ripple for enhanced security
The corrugated plate at the top adopts arc structure, the side is not closed, and it is not easy to accumulate coal dust. Avoid the risk of high temperature ignition and accumulation of coal seam at the top of the shell, and enhance product safety.
The tap adjusting hand hole is set vertically for more convenient operation
Compared with the top plate, the operator can operate by standing without climbing and avoid metal parts falling into the transformer body due to careless operation, which is more convenient and safe.
Frame chassis, small size, easy to expand
The bottom of the shell adopts the medium thick steel plate and the tractor as a whole welded frame structure to make full use of the bottom space and reduce the height of the whole machine. For power center products, chassis expansion is more convenient. The wheels can be mounted under or at both ends of the housing, with an easy choice of wheelbase or center of gravity adjustable modes.
Intelligent terminal monitoring, more efficient operation and maintenance
The intelligent monitoring terminal is equipped with standard communication interface, which can easily access the coal mine monitoring system to realize remote monitoring and transformer life cycle management.
KBSG series of mining flameproof dry transformers manufactured by varelen Easy to select high quality materials to enhance operation reliability, normal operation maintenance-free, in line with the latest national standards. It is applicable not only to the underground mine with gas, coal dust and explosion risk, but also to the tunnel mining with gas, the mobile working face of non-coal mine mountains and other environments.
Since the advent of KBSG series flameproof dry transformers for mining, it has provided tens of thousands of flameproof transformers to more than 1000 customers across the country, which are widely used in coal, steel, petrochemical, metallurgy and other special industries. After years of operation and use, the safety and stability performance of the product has been repeatedly tested by the market and is well recognized by customers.
