transformer is an electrical device used to convert high voltage or high current into low voltage or low current for the purpose of measurement and protection of power systems. Transformers typically consist of a core and coils, with the coils wound around the core. When the current or voltage passing through the transformer changes, the current or voltage in the coils also changes accordingly. This change can be measured and recorded to monitor the status and performance of the power system.

The main function of a transformer is to convert high voltage or high current into low voltage or low current for measurement and protection of power systems. In power systems, high voltage and high current can pose risks to equipment and personnel, so it is necessary to convert them into low voltage and low current for measurement and monitoring. Transformers can also be used for the protection of power systems. For example, when a fault occurs in a power system, transformers can detect abnormal changes in current or voltage and trigger protective devices to ensure the safety and stable operation of the power system.

There are many types of transformers, including current transformers, voltage transformers, and combination transformers. Different types of transformers are suitable for different power systems and application scenarios. For example, current transformers are typically used to measure current in power systems, while voltage transformers are used to measure voltage. Combination transformers can measure both current and voltage simultaneously, enabling comprehensive monitoring and protection of power systems.

In summary, transformers are essential devices in power systems. They convert high voltage or high current into low voltage or low current for measurement and protection of power systems. Different types of transformers are suitable for different power systems and application scenarios, helping to achieve comprehensive monitoring and protection of power systems.

Single-phase indoor high-voltage transformer is a kind of power transformer which is mainly used in the high-voltage side of single-phase power system. Here are some information about the technical parameters and applications of single-phase indoor high-voltage transformers:

Technical Parameters:

GGAj02 series single-phase full-wave high-voltage silicon rectifier transformer: this transformer has two impedance forms for users to choose, medium resistance and high resistance. Medium resistance rectifier transformer combines the advantages of domestic high and low resistance rectifier transformer, suitable for the electric field working conditions of poor and large load changes; high resistance transformer design circuit total resistance of 35-40%, the use of the main circuit total resistance of the integral characteristics of the rectified output voltage waveform coefficient, in order to get a lower peak-to-average value ratio of
.
DC-50KVA/27.5KV/0.23KV single-phase dry-type transformer: design life of more than 30 years, impedance voltage of 6.5%, the use of energy-saving transformers, in line with national energy-saving related regulations
...
Fully self-protected single-phase column-mounted transformer: product models include DH15-M or D11-M, rated voltage of 10kV/(0.22~0.24)kV or 2×(0.22~0.24)kV (or voltage proposed by the user), with tapping ranges of ±5%; ±2×2.5%, frequency of 50Hz, and coupling group labeling of II0 or II6, applicable to outdoor environment.

Applications:

Single-phase distribution transformer installation location selection: the installation location of single-phase distribution transformer is less restricted by geographical factors, and more constrained by the load nature factors. In the three-phase distribution transformer power supply radius is too large, the load is too heavy or there is no three-phase electricity users, the installation of single-phase distribution transformer can solve the problem of low voltage, capacity increase, reduce losses, and save investment.
Application Example: In Suqian City, the installation of single-phase distribution transformer can solve the problem of low voltage and capacity increase and save investment.

Application examples: in Suqian city, the widespread installation of single-phase distribution transformers has brought significant social and economic benefits. For example, a 4 houses 16 units of 160 residents of the city south resettlement district, by 1 S7-315/10 three-phase distribution transformer power supply, changed to 8 sets of 50kVA suspended single-phase distribution transformer power supply, the average low-voltage power supply radius from 280m reduced to 12m, significantly improving the voltage qualification rate and the user power supply reliability rate.

The average low voltage power supply radius was reduced from 280m to 12m, which significantly improved the voltage compliance rate and the reliability of power supply to users.
This information provides some basic technical parameters and application scenarios of single-phase indoor high-voltage transformers, which helps to understand their role and advantages in the power system.
