Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a discharge device for surge arresters. Background Technology

[0002] A surge arrester is connected between the cable and the ground, usually in parallel with the protected equipment. Surge arresters effectively protect communication equipment; they activate in the event of abnormal voltage to provide protection. When the communication cable or equipment is operating under normal operating voltage, the surge arrester does not function and is considered an open circuit to the ground. However, if a high voltage occurs that threatens the insulation of the protected equipment, the surge arrester immediately activates, diverting the high-voltage surge current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. Once the overvoltage dissipates, the surge arrester quickly returns to its original state, allowing the communication line to operate normally.

[0003] However, existing surge arrester discharge devices are expensive. Utility Model Content
