Difference between high voltage power supply and low voltage power supply

In our daily life, we need the power supply system to provide us with continuous power, but in the whole power supply system industry, there is a problem that is very confusing and fuzzy. Because the answer to this question has always been that there is no standard or boundary to measure it, and also because different people, different fields and different occasions produce different ideas. However, there are some different opinions. So people are more and more vague about their concepts and differences. This problem is the difference between high-voltage power supply and low-voltage power supply. At the same time, strong electricity and weak electricity are the same reason.

We don’t need to pursue the answer to this question. First, let’s find out what causes people to be confused about their differences. This is about some regulations of the state and power supply enterprises. I think it’s because of these rules that people don’t understand their differences. Let’s learn about it together! Let’s talk about what the state’s regulations are for the “power” industry. If the voltage of electrical equipment is more than 250V, it can be called high-voltage power supply. If it is lower than this number, it will naturally belong to low-voltage power supply. Then the State Grid Enterprise’s regulations are that the voltage of electrical equipment is more than 1000V, which can be called high-voltage power supply. If it is lower than this number, it can be called high-voltage power supply Numbers also belong to low-voltage power supply. From these two regulations, it is not hard to find that the data gap between them is quite large, but people with confidence can find that the former is electrical equipment and the latter is electrical work. Electrical equipment refers to the phase voltage, and electrical work refers to the line voltage. Although the data is different, it seems to be the same in the industry

High voltage:

According to definition 2.1 in GB / T 2900.50-2008, high [electric] voltage usually refers to the voltage level higher than 1000V (excluding); it refers to the distribution line with AC voltage above 1000V or DC voltage above 1500V.

Low voltage:According to the 2013 edition of the State Grid Corporation of China’s code of electric power safety, low voltage refers to the voltage level of 1000V and below. For power generation and power supply of power plant, it is about 6000V ~ 7000v. The above is high-voltage power, and the below is low-voltage power.

Shandong Hhuarui’s high voltage power supply is safe and reliable, and the price is low. Welcome to consult with interested friends
