What is air cooling?

The basic principle of air cooling technology is to take away the heat generated by battery cells through flowing air, thus keeping the battery temperature within a reasonable range. As a heat transfer medium, air can achieve heat exchange through natural convection or forced convection.

  • Natural convection:Natural convection refers to the phenomenon in which air flows by itself due to the difference in air density caused by temperature differences.In some cases, natural convection can be used to achieve simple thermal management, but this is usually not sufficient to meet high-intensity or high-density energy storage requirements.

  • Forced convection:Forced convection is to accelerate air flow through fans or other mechanical devices, thereby improving heat exchange efficiency.In container energy storage systems, forced convection is usually used to achieve effective thermal management.

What are the troubleshooting methods for current transformers?
What are the troubleshooting methods for current transformers?
As a front - line fault maintenance worker, I deal with current transformers (CTs) daily. A CT’s secondary winding in operation must never open - circuit! Once open - circuited, the secondary current and demagnetizing potential vanish. All primary - side magnetic potential then becomes the iron core’s exciting potential, sharply increasing its magnetic flux density. High voltage on the secondary side will endanger safety anytime.Despite strict power operation regulations, user electr

What are the causes of current transformer faults and the countermeasures for faults?
As a front - line maintenance technician, I deal with current transformers (CTs) daily. CTs convert high - magnitude primary current to low - magnitude secondary current for substation/line protection and measurement, operating in series long - term. However, they face faults from external (unbalanced loads, wrong wiring, etc.) and internal (insulation defects) issues. These faults, like secondary open - circuits or insulation breakdown, harm measurement accuracy, protection operation, and grid

With the development of modern economy and science and technology, photoelectric current transformers (PECTs) have fully transitioned from the trial operation stage to practical application. As a front - line testing personnel, I deeply feel their importance in the power system during daily work. I also realize the necessity of conducting in - depth research on their testing systems and calibration methods. This not only promotes the engineering application of PECTs but also enables the accurate

Impact Analysis of Voltage Transformer Installation on Line Side vs. Load Side of Power Inlet Circuit Breaker for (ATS)
Automatic backup switching (ABTS) devices are core components ensuring the safe, reliable, and stable operation of factory power grids. Their startup logic strictly follows the dual criteria of "loss of voltage in the working power supply + no - current detection", effectively avoiding misjudgments caused by secondary disconnection of voltage transformers (VTs) or maloperations of ABTS due to secondary circuit faults of current transformers (CTs). The activation condition requires both "no volta
