Issues with the high-end version
Thread Content
Why do factories opt for higher-spec models? What are the advantages of higher specifications?
Hehe, the question is way too concise: lol. Try to add some context to it; P. By \"high-end configuration,\" it refers to a configuration of high quality – characteristics such as quality assurance, long service life, no need for maintenance, and energy savings. Is that what is meant?
It refers to high-voltage power distribution, \ud83d\ude2c
It refers to high-voltage power distribution. Why is it necessary to use high-voltage distribution? Can’t low-voltage distribution be used instead?
If money is no object, it’s best to go for a high-end model – one that is safe, durable, and operates stably; these are the qualities of a high-end product. Take high-voltage arc extinguishing switchgear as an example: originally, they were oil-immersed types that could not be started more than three times in a row, but later on vacuum arc extinguishing types were used, which offered significant improvements in terms of size, safety, and the ability to operate continuously; as a result, the oil-immersed types were inevitably phased out. There are also supporting facilities such as water rental cabinets. Cost-performance is something to consider, but for electrical appliances, it’s better to go with a higher-end model.
The power supply lines for factories of a certain scale are usually high-voltage lines; without high-voltage power, how can it be converted to low voltage? There are also very few motors with a power rating of 355 kW or higher that come in low-voltage versions; even if such cables do exist, it is difficult to install them.
For smaller capacities, a lower-specification version is used; for larger capacities, a higher-specification version is necessary. Operating with low-voltage power distribution at large capacities is not economical as it results in high losses.
By \"high-specification,\" it is meant that a high-voltage incoming circuit is used as the power source, with a corresponding step-down substation installed. This setting is directly related to the conveying capacity, investment, and power supply radius, as well as to the voltage level of the electrical load. Currently, it is used as the power supply and distribution voltage for factories at 220kV, 110kV, and 35kV, which are the standard voltage levels for high-voltage systems
With high voltage, the current is lower; accordingly, the costs of cables and motors also decrease
