AC Drive Fusing TECHNICAL BULLETIN
■描述
●MCE注意到，一些装置没有适当尺寸的主线断开保险丝。为了保护下游的电梯控制设备，干线断开保险丝的适当尺寸至关重要。当隔离变压器与电梯控制器一起使用时，干线断开保险丝的适当尺寸变得更加重要。当使用隔离变压器时，它会提供额外的阻抗，从而限制由于故障而产生的可用短路电流，从而导致超大保险丝无法打开和中断故障电流。
●MCE未就干线断开熔断器的尺寸提供任何建议。然而，MCE确实为控制器提供了满载电流（FLA）。电梯承包商或电气承包商有责任根据MCE提供的FLA确定主线断开保险丝的尺寸。
●此外，MCE建议在所有AC驱动牵引力控制装置内使用高速J级二次保险丝。二次熔断器位于电梯控制器内部，并连接在主线和驱动器之间，或隔离变压器的二次和驱动器之间。

What are ESS DC Energy Storage Fuses？
The DC energy storage fuse is a critical component in ensuring the safety and reliability of modern energy storage systems. By providing fast-acting protection against overcurrents and short circuits, these fuses help maintain the integrity of energy storage systems in various applications, from residential solar setups to large-scale industrial energy solutions.
Essential Knowledge for Selecting Automotive Fuses
When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase； When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circuit.
Self Recovery Performance and Working Process of Self Recovery Fuses
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
What is the importance of fuses in charging pile safety and reliability?
As a safety mechanism, fuses in charging pile help prevent potential damage to the internal components of the charging station, ensuring safe and reliable charging operations. It is very important to choose an appropriate fuse for a charging pile. Factors such as rated voltage, rated current, breaking capacity and compliance with relevant safety standards should be considered.
Common Sense for Fuses
A fuse refers to a self destructing fuse that experiences significant surges or other current exceeding limits in a circuit； In order to protect the components of other parts of the circuit where the fuse is located and the equipment is normal, the cost of replacing the fuse can be ignored compared to replacing the entire circuit that may be damaged. Due to the fact that fuses are a common element that needs to be replaced, we will introduce two basic concepts and provide a more in-depth introduction to fusion applications and testing and diagnostic methods.
Why Do Fuses Have High Resistivity
A fuse is a wire made of lead antimony alloy with a lower melting point and a lower resistivity. The more voltage constant resistance can be compared, the more it can detect micro current resistance that exceeds the working range. A high current is required to fuse the resistance, which can burn out the electrical appliance and prevent it from melting. Some principles use the current thermal effect fuse to control the current flow and allow the current to flow.
Encapsulation Forms of Current Fuses
The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.
The Installation Precautions for Current Fuses
The installation of current fuses is crucial for ensuring the safety and proper functioning of electrical circuits. Here are some important installation precautions to keep in mind.
Principle of Resettable Current Fuses
Resettable current fuses offer a unique solution for protecting electrical circuits while providing the convenience of being reusable. Here‘s how they work.
GRL Provides Fuses, and Fuse Switches in GW155 Wind Turbines
GRL participated in Goldwind‘s 3 million kW wind power poverty alleviation project in Inner Mongolia, China, providing fuses and fuse switches for the GW155-4.5MW wind turbines. The wind power system includes wind turbines, overhead lines, transformers, and grid boxes, with GRL‘s 160A fuse switch disconnector applied to ensure reliable protection. The GW155-4.5MW wind turbine has maintained an availability rate above 99.7%.
Discussion on the Testing Method of Chip Fuses
We know that there are many series of fuses in the electronic component market, including patch fuses. This series of fuses is commonly used in factories, with few being used by individual users. But what should we pay attention to when testing patch fuses? Today, editor Dai Liang, let‘s take a look together. Firstly,The detection method for patch fuses is recommended to be based on the following aspects: normal current, fusing current, open circuit voltage, short circuit current, impulse current, and ambient temperature.
