Surge voltage protection apparatus

A surge voltage protection apparatus comprising:

• a surge voltage absorbing component electrically connected to a voltage input side of a power supply apparatus;
• a ground component electrically connected to the surge voltage absorbing component;
• an electrical status sensing circuit electrically connected to the surge voltage absorbing component and the ground component;
• and
• a control unit electrically connected to the electrical status sensing circuit and the power supply apparatus,
• wherein the surge voltage absorbing component receives a surge voltage, so that the electrical status sensing circuit senses an electrical status between the surge voltage absorbing component and the ground component to obtain an electrical data;
• the electrical status sensing circuit sends the electrical data to the control unit;
• after the control unit receives the electrical data, the control unit determines the electrical data;
• when the electrical data is greater than an electrical data predetermined value, the control unit informs the power supply apparatus that the electrical data is greater than the electrical data predetermined value, so that the power supply apparatus is turned off to protect the power supply apparatus.
