Using SVR Line Automatic Pressure regulator to Solve the Low Voltage Problem of 10kV Line

The current measures taken to address the issue of "low voltage" in rural power grid lines mainly include the following: the cross-sectional area of newly constructed wires; Adjust the main transformer tap of the substation to change the system voltage; Reasonably distribute reactive power compensation equipment in the system to improve the distribution of reactive power flow in the power grid; Transform the line and increase the load of the pump station; Increase the number of outgoing lines in the substation to share the load of the original line. The above measures have the following issues.

Three Major Trends in the Development of Intelligent Terminal Distribution Industry and Technology

In recent years, the distribution industry in China has developed rapidly. In addition to strictly adhering to engineering standards, designers also need to continuously deepen their understanding and mastery of new trends in intelligent equipment and technology in order to ensure that they can provide high-quality products while meeting the increasingly strict needs of customers to a large extent. Based on my over 20 years of professional design experience in the distribution industry, intelligent terminal distribution systems can only become a benchmark product in the industry and lead the development direction of the future distribution industry by making breakthroughs in safety, diversity, and innovation.

Thoroughly dissect and decompose the detailed structure of three-phase asynchronous motors

A three-phase asynchronous motor consists of two basic parts: a fixed stator and a rotating rotor. The rotor is installed in the stator cavity and supported on two end covers by bearings. In order to ensure that the rotor can rotate freely within the stator, there must be a gap between the stator and the rotor, called an air gap. The air gap of an electric motor is a very important parameter, and its size and symmetry have a significant impact on the performance of the motor.
