What is a Solar Lantern ?

AC load banks are electrical devices used to simulate real-world loads and are widely applied in power systems, communication systems, automation control systems, and other fields. To ensure personal and equipment safety during use, the following safety precautions and guidelines must be observed:Select an appropriate AC load bank: Choose an AC load bank that meets actual requirements, ensuring its capacity, voltage rating, and other parameters satisfy the intended application. Additionally, sel

Installation precautions for Type K thermocouples are critical to ensuring measurement accuracy and extending service life. Below is an introduction to the installation guidelines for Type K thermocouples, compiled from highly authoritative sources:1.Selection and Inspection Select the appropriate thermocouple type: Choose the right thermocouple based on the temperature range, medium properties, and required accuracy of the measurement environment. Type K thermocouples are suitable for temperatu

Causes of Fire and Explosion in Oil Circuit Breakers When the oil level in an oil circuit breaker is too low, the oil layer covering the contacts becomes too thin. Under the effect of the electric arc, the oil decomposes and releases flammable gases. These gases accumulate in the space beneath the top cover, mixing with air to form an explosive mixture, which can ignite or explode under high temperature. If the oil level inside the tank is too high, the released gases have limited space to expan
