Lightning Damage to Electronics
-- 閃電對電氣用品造成的傷害
文/曾郁青

Lightning typically damages electronics in one of two ways.(雷擊通常以下列兩種方式之一損壞電氣用品。)

The first is a direct lightning strike to the home, which is an infrequent occurrence. A direct lightning strike will cause significant damage to electrical and nonelectrical items in the home.(第1種是閃電直接雷擊於建築物,此種情形較不常發生,此種直接雷擊會對家中電氣和非電氣用品造成巨大的的損害。)


In many instances, this will start a fire, often in the wiring within the walls or the attic.(在許多例子中,此種直接雷擊會造成火災,通常發生在牆壁內或頂樓的室內配線。)

It can also cause structural damage to the roof, chimney, or sometimes the windows or foundation.(它也能造成建築物屋頂、煙囪的損壞,有時也會造成窗戶或地基的損毀。)

Moreover, electronics plugged into an electrical system that receives a direct lightning strike typically cannot be protected by a surge protector.(此外,電氣用品中有插電者,在接收到直接雷擊時通常無法被突波保護裝置所保護。)

The more common scenario is for a nearby lightning strike to enter the home through wires or pipes that extend outside the home.(更常見的情形是閃電擊中建築物周圍的間接雷擊,藉由暴露在外的電纜或管線侵入建築物內。)

The energy from a nearby lightning strike can travel through communication wires, directly from a utility pole into the home’s electrical panel, or through conductive metal.(間接雷擊產生的能量,可以藉由通訊纜線、電線桿與家中配電盤間的線路或可導電的金屬傳遞。)

Damage from this type of event is generally less severe than that of a direct strike.(此類事件造成的傷害通常不如直接雷擊造成的傷害嚴重。)

The electrical system of a home or business is one of the most frequent points of entry of increased voltage from a lightning or surge event.(家庭或企業的電氣系統是閃電或突波事件對建築物內增加電壓最頻繁的進入點之一。)

When lightning strikes a nearby power line, it travels the path of least resistance from the power line to the meter and then into the home’s electrical panel.(當閃電擊中建築物附近的電力線時,它會從電力線到電錶間的最小電阻路徑行進,然後再進入家用配電盤。)

If the electrical panel is equipped with a whole-house surge protection device, the surge will stop there.(如果配電盤配備了全屋突波保護裝置,則突波將會停止在那裡。)

If the surge is not stopped at the electrical panel, it can then travel over the surface of the wiring to the home, burning the insulation and fusing the wires together.(如果在配電盤處沒有停止突破,則它可以藉由電線的表面傳遞到家中,燃燒電線上的絕緣材料並造成電線接觸融熔在一起。)

Moreover, it can travel through the wiring to the outlets and damage electronics not plugged into a surge protector.(此外,它可以透過電線線路到達插座並損壞未插入突破保護器的電氣物品。)

Because the wiring is within the walls of the property, it can be difficult and costly to determine the extent of the damage.(由於電線線路位於房屋的牆內,因此評估損壞的程度將會很困難且成本高昂。)
