How to protect the system of the SSE technology platform 2022? It is important to maintain power failures as low as possible, which is why the design should have low thermal opposition. The article also discusses the importance of using control and protection devices.
Protecting the System of SSE Technology Platform 2022
The most important part of a power transformer is the winding. It does not matter whether you are protecting the transformer from overcurrent and overvoltage conditions or whether you are providing a controlled output current or voltage level.
If you are feeding the transformer with reactive energy, then the winding must be properly connected to the source. Often, it is difficult to assess whether such a connection will ensure proper operation of the power transformer in terms of losses and operating temperature.
Overcurrent Protection Devices
A power transformer is to have a certain current level flowing through it. It is also essential that this current level does not change suddenly. These two requirements can be met by using overcurrent protection devices on the transformer.
Overcurrent Protection Devices are to protect the power transformer from overcurrent. There are two types of overcurrent protection devices: fuses and relays.
Fuses
Fuses are low-cost, fast-acting, and simple to use overcurrent protection devices. They are extensively when it is necessary to protect power transformers from single-phase faults, such as phase-to-ground faults or phase-to-phase faults.
The most important characteristic of a fuse is its current level (A). This current level must be higher than the maximum allowable short circuit current of the transformer.
For example, if the maximum available short circuit current is 10 kA, then the fuse should have a current rating of at least 10 kA. The fuse must have a current rating that is higher than the maximum available short circuit current.
Relays
Relays are for more complex applications, such as when it is necessary to protect the transformer from three-phase faults. In addition to overcurrent protection, the relay must also have other protection functions, such as control and protection functions.
The relays used in power transformers are fuses. Depending on the particular application, they provide voltage or current limiting.
Challenges
Among the challenges faced when protecting the system of the SSE technology platform, 2022 is the need to protect voltage or current overcurrent.
The system must also be from short circuit currents, which may lead to high temperatures in various parts of the system. There is a need to protect the transformer from overloads, surges, dips, and voltage sags.
The protection system must provide operation in hard conditions. This may include operating in an environment with high temperatures or a low-temperature environment with extreme humidity.
In such an environment, it is necessary to protect the transformers from thermal overloads and electric overloads that may cause a fire in a transformer. In addition, there is a need to control the output voltage and current to ensure proper operation.
Conclusion
To protect the system of SSE technology platform 2022, we need overcurrent protection devices designed to protect the transformer and other components.
These devices are to protect against overloads, surges, dips, voltage sags, and short circuit currents. In addition to overcurrent protection, they must also have control and protection functions.
