Introduction Of Surge Protector-click To View Details
Surge protectors are commonly known as surge protective device, also known as surges. As the name suggests, they are pulses or instantaneous overvoltages with steep rising edges that exceed the normal working voltage. Possible causes of surges include: direct lightning, induced lightning (introduced into the power supply and use system), heavy equipment start-up and stop, short circuit, power switching (transient overvoltage or overcurrent occurs due to the low impedance effect at the moment of start-up and stop), and other surge sources include incorrect wiring, power supply, company equipment problems, and aging of power lines. Its hazards are mainly: accelerating equipment aging, shortening equipment life, and even damaging equipment; endangering production safety and stability; interfering with and damaging sensitive circuits, communications and other equipment.
surge protection device must start with assessing potential risks and identifying the objects to be protected, adopting a comprehensive and systematic protection concept, and paying attention to the protection of all power supply, data, and communication interfaces. This is the only way to provide comprehensive and effective protection for power supply systems, data networks, factory equipment, building electrical systems, etc. High-quality products and efficient solutions to effectively protect against surge hazards.
Surge protectors are mainly used to prevent and prevent the damage caused by surges to equipment. In addition to external lightning protection measures such as lightning rods, down conductors and grounding devices, the protected objects also need to be equipped with surge protectors. This is because external lightning protection facilities cannot prevent lightning-induced surges from being conducted along wires, pipes, etc. and ground potential counterattacks. Especially when there are high-value information electronic equipment and power electronic equipment in the building that have a greater impact after a failure, since these devices use large-scale integrated circuit chips and have a high degree of integration, their ability to withstand lightning surges is much lower than that of traditional electrical equipment, and surge protectors are even more necessary.
