Product introduction
The SZ13 on-load voltage regulating transformer is a new product independently developed by our company. This product is a new technology and energy-saving distribution transformer. It has two rated capacities, large and small, and the two rated capacity operating modes can be automatically switched. It solves the problem of The seasonal load changes of the 10kV distribution network are relatively large, resulting in large transformer losses. It overcomes the operation and maintenance problems caused by manual capacity adjustment of unloaded capacity transformers after power outages. The use of SZ13 type on-load voltage regulation is compared with two SZ13 type primary and secondary transformers. First of all, the cost of equipment purchase and installation is reduced, and the floor space is reduced, and the operation and maintenance workload of the short-circuit switch during construction is significantly reduced. At the same time, compared with the SZ13 ordinary transformer, the no-load loss of the SZ13 type on-load voltage regulating transformer is reduced by more than 50%. In addition to being suitable for rural power grids with relatively large seasonal load changes, it is also suitable for some urban commercial areas, development zones, industrial areas, radio stations, oil fields, etc. that have significant day and night load changes.

◆Use oxygen-free copper wire with lower resistivity, and after a series of additional surface treatments, it is smoother and has no burrs or sharp corners, which makes the load loss of the transformer lower and the electrical performance more reliable:
◆Use high-quality silicon steel sheets. With the improvement of performance level, use silicon steel sheets with lower unit loss to make the transformer no-load loss lower.
◆Use high-quality laminated wood insulation, which will never crack, and will not move even under the action of short-circuit current.
◆Use transformer oil that has been deeply filtered, with lower water, gas and impurity levels, and the transformer will work more reliably.
◆Use high-quality rubber sealing materials to effectively prevent aging and prevent leakage.
◆All raw material factories have been strictly reviewed in accordance with the national standard IS09000.Good technical and economic performance
◆This product can significantly reduce the transformer no-load loss by 50-60%
◆Reduce the reactive power loss of the power grid by 20-30%
◆If this technology is fully applied to rural power grids, 10 billion kWh of electricity can be saved each year;
◆Save 3 million tons of standard coal each year, equivalent to reducing CO2 emissions by 5 million tons.
◆This project has been highly valued by the State Grid, included in the National Ten-Five Power Saving Plan undertaken by the National Electric Power Science Research, and included in the power construction specifications in the new rural construction.Fully sealed
◆The M in S11M)R indicates that the oil tank adopts a fully sealed structure. Compared with ordinary oil-immersed transformers, the fully sealed distribution transformer has eliminated the oil storage cabinet. The corrugated fins of the oil tank replace the oil pipe as a cooling and heat dissipation element. The corrugated oil tank is made of high-quality cold-rolled thin plates on a dedicated production line. The corrugated fins can expand and contract the transformer oil, thereby isolating the transformer from the atmosphere, preventing and slowing down oil degradation and insulation moisture, enhancing operational reliability, and normal operation without maintenance.
◆The surface of the corrugated oil tank is degreased, derusted, and phosphated before being coated with three-proof paint, which is suitable for use in metallurgy, petrochemical, mining and other environments.Reliable structure
◆ Based on the traditional structure and mature technology, our company has made many improvements, such as:
◆ Spiral coil with longitudinal oil channel, better internal heat dissipation;
◆ Improved effective support of coil end face, stronger short-circuit current resistance;
◆ Adopted new lifting structure and body positioning structure to ensure more reliability in long-distance transportation and operation;
◆ We also have many unique and reliable structures to serve you;
◆ Selecting a transformer with higher performance level will have a higher level of technical content.Technical parameters of S11-M-ZT on-load voltage regulating transformer
