The following is a summary of Hengfengyou Electric MARTIN experience in serving oil-immersed and dry-type transformers in Nigeria for many years
Nigeria is the largest economy in Africa and a major producer and user of electricity. However, the country's power industry faces many challenges, including imbalanced electricity demand and supply, aging equipment, poor management, and corruption.
Firstly, the imbalance between electricity demand and supply in Nigeria is a major issue. Although the country has abundant natural resources such as coal, natural gas, and hydropower, the electricity supply is still insufficient. This has led to frequent power outages and shortages, which have had a significant impact on industry, commerce, and households.
Secondly, the aging of power equipment in Nigeria is also a problem. Due to a lack of investment and maintenance, many equipment has become outdated or damaged, resulting in a decrease in power production capacity. In addition, due to the aging of the power transmission network and distribution system, the power loss rate is also high, which further weakens the reliability of power supply.
Thirdly, poor management and corruption in the Nigerian power industry are also major challenges. In the past few years, the media has reported multiple corruption cases involving senior officials and management personnel in the power industry. This corrupt behavior has led to unreasonable allocation of resources, inefficient investment decisions, and corrupt transactions, thereby damaging the healthy development of the power industry.
In order to address these issues, the Nigerian government has taken a series of measures to improve the situation in the power industry. For example, large-scale power projects have been implemented, including the construction of new power plants and the upgrading of transmission networks. In addition, the government has launched a series of policy measures aimed at strengthening regulation, combating corruption, improving energy efficiency, and improving service quality.
However, the implementation of these measures requires investment of time and resources. The power industry in Nigeria still faces many challenges that require the joint efforts of the government, the private sector, and international partners to address.
Nigeria mainly uses three-phase oil-immersed transformers for the following reasons:
High demand for electricity: Nigeria has a very high demand for electricity, requiring a large amount of electricity supply, therefore requiring the use of large transformers to meet the demand.
Rapid economic development: Nigeria is one of the economically developed countries in Africa, with a high degree of industrialization and a need for a large amount of electricity support, thus requiring the use of large transformers.
The main technical advantages of three-phase oil-immersed transformers include the following:
Low noise due to environmental protection and energy saving: the use of lossless Ferrite core, stepped iron core interface and foil coil structure reduces the noise level and makes it more environmentally friendly and energy-saving.
High reliability: the stability of the transformer has been improved by carrying out basic scientific research in the fields of electromagnetic field theory, casting and manufacturing process, real-time hot spot temperature raising, basic principles of partial discharge, warranty period management mode, reliability theory, and certification of Factor of safety.
Certification of ecological and environmental protection characteristics: Based on the European standard HD464, in-depth research and certification have been conducted on the climate resistance, ecological resistance, and fire safety characteristics of oil immersed transformers.
Large capacity: Three-phase oil immersed transformers have a large capacity and can meet the power consumption needs of large cities. They are suitable for various load critical locations, such as urban network regional distribution stations, residential communities, and large and small industrial and mining enterprises.
Multipurpose composition and intelligent system: Transformers have multiple uses, such as mandatory air cooling, maintenance of the casing, power measurement and detection, computer interface, enclosed busbar, various low-voltage side group outgoing lines, etc. The TTU intelligent system socket has been introduced, which has functions such as data analysis methods, condition control, and condition description, making it a portable intelligent system.
Multi industry development prospects: Three-phase oil-immersed transformers are not only used for distribution transformers, but also for special transformers such as excitation regulator transformers in power plants, auxiliary transformers, traction rope electronic rectifier transformers in urban rail transit, high current value heat treatment
furnace transformers, nuclear power plants, ships, and comprehensive service platforms in oil extraction plants, as well as for various purposes and industries. They have broad development prospects.
Hengfengyou Electric has exported multiple 11kv50kva dry-type transformers and oil-immersed transformers this year, and the equipment is currently in good use.
Nigeria's requirements for three-phase oil-immersed transformers mainly include the following aspects:
Voltage ratio and connection group: Nigeria's power system adopts high-voltage transmission and low-voltage distribution, so oil immersed transformers need to meet the corresponding voltage ratio and connection group requirements to ensure safe operation in the power system.
Capacity and load capacity: Oil immersed transformers in Nigeria need to meet local load requirements and have a certain overload capacity. Select appropriate capacity and load capacity based on local electricity demand and transformer capacity requirements.
Insulation level and withstand voltage level: Oil immersed transformers need to meet the insulation level and withstand voltage level requirements of the Nigerian power system to ensure safe operation under high voltage conditions. Select the appropriate insulation level and withstand voltage level according to the requirements of the local power system.
Protection level: Oil immersed transformers in Nigeria need to have a certain level of protection to prevent the external environment from affecting the operation of the transformer. Choose an appropriate level of protection based on local climate and environmental conditions.
Energy efficiency level: With increasing global attention to energy efficiency, Nigeria is gradually promoting oil immersed transformers with higher energy efficiency levels. When selecting oil immersed transformers, their energy efficiency level should be considered and comply with local energy efficiency requirements.
Environmental requirements: Nigeria has high requirements for environmental protection, so when choosing oil-immersed transformers, attention should be paid to their environmental performance, such as compliance with local regulations and standards in terms of noise, emissions, waste disposal, etc.
