Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, and more specifically, to a core structure of a surge protector. Background Technology

[0002] Surge protectors, also known as lightning arresters, are electronic devices that provide safety protection for various electronic equipment, instruments, and communication lines. When a surge current or voltage spike suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing damage to other equipment in the circuit. Graphite gap surge protectors are surge protectors that use graphite material as the discharge gap. They are mainly used to protect electronic equipment from damage caused by lightning or transient overvoltage. Through the conduction and shunt of current under high voltage conditions using graphite electrodes, lightning or abnormal current is introduced to the ground, preventing equipment from being damaged by high current / voltage surges. However, existing surge protector core structures are not compact enough and have poor reliability. Therefore, we propose a new surge protector core structure. Utility Model Content
