Fuses are devices designed to protect electrical circuits, equipment and people from damage caused by an overload of electrical current, or from short-circuits. The BK/ATM-5 is a type of fuse designed for use in high-voltage electrical systems. It is designed to operate automatically when a current higher than the normal level is encountered.The BK/ATM-5 is a dual-element fuse, meaning it has two elements within its design. One element is known as the primary element, which is designed to open when a current greater than the normal level is attempted to pass through the circuit, thus interrupting the circuit. The other element is called the back up element, which is designed to provide additional protection in the event that the primary element fails.The BK/ATM-5 is a high-powered fuse, with a rated voltage of up to 120 kilovolts (kV). It is ideal for use in high-voltage electric power transmission systems, such as power grids, substations, and power distribution systems. It is also suitable for use in industrial equipment, such as transformers and inverters.The BK/ATM-5 combines two features in its design that make it ideal for these applications. First, it is designed to interrupt the current quickly and reliably, ensuring that the circuit is not damaged in case of an overload or short-circuit. Second, it has a high melting point, meaning that it can handle higher temperatures than other types of fuses, making it suitable for use in hotter environments.The BK/ATM-5’s design features a ceramic body that is filled with a metal alloy. This metal alloy contains tiny particles of silver and copper, which act as the conducting medium for the current. The alloy also contains tungsten, which has a higher melting point than other metals. This enables the fuse to handle higher currents without melting or becoming damaged.When the current passes through the BK/ATM-5, the current is conducted through the metal alloy. The tungsten particles become hotter and start to melt, and the current is interrupted. At the same time, the metal alloy can also absorb some of the heat, cooling down the circuit and preventing it from becoming damaged. The fuse then resets itself, and the circuit is restored.The BK/ATM-5 is an important safety device in a variety of electrical systems, providing overcurrent protection and fault protection. Its dual-element design ensures quick interruption of high currents, while its high melting point ensures it can handle high temperatures. Its ceramic body is also designed to absorb heat and prevent circuit damage. With all these features combined, the BK/ATM-5 is a reliable and effective choice in the application field of high voltage transmission and industrial power systems.
