a 10 mva 33 11kv electric power transformer plays an essential role in power transmission and distribution. Conso Electrical Technology and Science Co., Ltd focuses on assemble a high quality 33kv electric power transformer. Since the well development from 2006, Conso Electrical has built a Well-structured quality management system as a power transformer manufacturer. The Engineer will inspect each production procedure after designing the 33kv power transformer. Factory test is necessary to each 10 mva 33 11kv electric power transformer, especially to shipping to oversea area, the leak testing will have multiple times.
1. Parallel Operation of Distribution Transformers
One of the reasons for overloading in power distribution transformers is the presence of significant load within a single circuit. To address this, implementing parallel operation allows for the independent operation of multiple circuits, thereby avoiding the problem of high load within a single circuit. When operating distribution transformers in parallel, it is crucial to ensure that the rated voltage ratios are equivalent, phase sequences match, voltages are comparable, and the capacity of transformers in parallel is not significantly different. In general, it is advisable for the maximum power distribution transformer capacity not to exceed three times the minimum power distribution transformer capacity.
2. power distribution transformer Capacity Expansion
Expanding the capacity of power distribution transformers is a common approach to addressing overloading issues. This method requires conducting a comprehensive analysis and investigation of existing power supply operations in various locations. It involves understanding electricity consumption patterns at different times, during different years, seasons, and months, particularly focusing on peak electricity usage. By establishing a mean model based on regular data and an outlier model based on peak consumption, with the maximum values of current transformer operating parameters as linear constraints, several parameter charts are created. These parameter charts are analyzed comprehensively to determine the power supply standard value and maximum power supply. Matching these values with the existing power distribution transformer operating parameters, the power supply standard value serves as the minimum, and the maximum power supply value as the upper limit, establishing the fundamental requirements for capacity expansion.
3. Application of High Overload power distribution transformers
To enhance the prevention of overloading in distribution transformers, the application of high overload transformers deserves special attention. High overload transformers are capable of continuous operation at 1.5 times the rated capacity for 6 hours, 1.75 times the rated capacity for 3 hours, and 2.0 times the rated capacity for 1 hour. This capability provides substantial support for preventing overloading in distribution transformers. Upon closer analysis, it becomes evident that high overload distribution transformers must handle current levels exceeding their rated current, and they use insulation materials meeting Class B or higher insulation heat resistance standards.
