1. Product Overview
This manual introduces the 1000 Kva Distribution Transformer Substation and 4000kva Three Phase 1000 Kva Oil Immersed Transformer Hermetically Sea series products, which are high-efficiency, low-loss three-phase power distribution equipment designed for industrial and municipal power supply systems. Adopting fully sealed oil-immersed structure design, the product covers 1000KVA to 4000KVA capacity grades, strictly complying with IEC 60076 international power transformer standards and global power distribution industry specifications.
The series of hermetically sealed oil immersed transformers integrates advanced electromagnetic design and high-quality insulating materials, effectively solving the problems of heat dissipation, insulation aging and external environmental interference of traditional distribution transformers. With stable three-phase power output performance, it can adapt to long-term continuous operation in complex power supply environments, and is the core key equipment for medium and low voltage power conversion in distribution substations.
Different from ordinary open-type transformers, this hermetically sealed oil immersed transformer adopts a fully closed internal structure, which completely isolates the internal insulating oil and winding components from the external air, avoiding moisture absorption, dust pollution and oxidation deterioration of insulating oil. It realizes maintenance-free operation in conventional service environment and greatly extends the overall service life of the equipment.
2. Core Product Characteristics
2.1 Hermetically Sealed Oil Immersed Structure
The core advantage of the 1000 Kva Oil Immersed Transformer Hermetically Sea is the fully hermetic sealing technology. The whole transformer body adopts welded integral sealing structure without breathing hole, which prevents external humid air, dust and corrosive gas from entering the interior. The internal insulating oil is completely isolated from the outside world, maintaining stable insulation performance and chemical properties for a long time. This design eliminates the hidden dangers of insulation reduction and equipment failure caused by oil emulsification and deterioration, and is especially suitable for humid, coastal and dusty harsh working conditions.
2.2 High Efficiency and Low Loss Performance
Thisthree-phase distribution transformer uses high-permeability cold-rolled silicon steel sheets and optimized three-phase symmetrical core structure, which greatly reduces no-load loss, load loss and excitation current. Compared with traditional ordinary transformers of the same capacity, the no-load loss is reduced by more than 20%, and the operating energy consumption is significantly optimized. The three-phase winding layout is uniform, ensuring balanced voltage and current output, effectively avoiding power loss and equipment heating caused by three-phase imbalance, and meeting the energy-saving and low-carbon operation requirements of modern power substations.
2.3 Excellent Heat Dissipation and Thermal Stability
Equipped with enhanced radiating fin structure and natural oil circulation heat dissipation system, the insulating oil with excellent thermal conductivity can quickly transfer the heat generated by core and winding operation to the external radiator for heat dissipation. The efficient oil circulation heat dissipation mode makes the 4000kva three-phase oil immersed transformer maintain stable temperature rise under full-load and long-term overload operation, avoiding equipment aging and performance degradation caused by overheating. The heat dissipation system is fully adaptive to continuous high-load operation of large-capacity 4000KVA equipment and intermittent peak load operation of 1000KVA conventional equipment.
2.4 High Safety and Strong Environmental Adaptability
The product has superior high-voltage insulation performance, with the insulating oil breakdown field strength far higher than air insulation medium, effectively resisting instantaneous voltage fluctuation and surge impact in power grid. The fully sealed structure has good waterproof, moisture-proof, dust-proof and corrosion-resistant capabilities, without regular oil detection, oil replacement and internal cleaning maintenance. The whole machine has low operation noise, stable mechanical performance, strong seismic resistance, and can operate stably in high temperature, low temperature, high humidity and other complex environments for a long time.
2.5 Standardized and Reliable Configuration
The series of distribution transformers adopts standard three-phase power design, with mainstream voltage level matching (10kV/0.4kV conventional voltage ratio), and supports ±2×2.5% voltage tap adjustment to adapt to different grid voltage fluctuation ranges. The vector group adopts Dyn11 standard configuration, which has good zero-sequence current resistance and unbalanced load adaptability, effectively improving the safety and stability of low-voltage power distribution system operation.
3. Core Product Purposes
As core power conversion equipment for power grid terminal distribution, the 1000 Kva Distribution Transformer Substation and 4000KVA high-capacity models are mainly used for voltage conversion and power transmission of medium and low voltage power systems. Its core purpose is to convert 10kV medium voltage industrial power into 400V low voltage civil and industrial power, realizing safe, stable and efficient power distribution and meeting the power demand of terminal electrical equipment.
In power substation systems, this hermetically sealed oil immersed transformer undertakes the key task of grid power distribution and voltage stabilization. It can balance grid load, suppress voltage fluctuation, ensure the continuity and stability of power supply, and avoid power supply interruption and equipment damage caused by grid voltage instability. For different capacity scenarios, the 1000KVA model is oriented to conventional medium-power power distribution demand, while the 4000KVA high-capacity model is dedicated to high-load and large-scale centralized power supply scenarios, realizing hierarchical and precise power distribution.
In addition, the equipment also has the function of isolating high and low voltage circuits, effectively isolating grid high voltage from terminal low-voltage electrical equipment, reducing the risk of high voltage leakage and electrical equipment burnout, and providing safe voltage guarantee for industrial production, commercial operation and residential power consumption.
