Nā koi hana uila pale Surge 1. Kāohi i ka pilina pololei Ke ʻoi aku ka kiʻekiʻe o ka volta hana hoʻomau Uc o ka mea hoʻopale kiʻekiʻe hiki ke loaʻa ma mua o ka waiwai ac rms o 50V, e hoʻokō kēia i kēia mau koi. No ka pale ʻana i ka hoʻopili pololei ʻana (nā ʻāpana conductive hiki ʻole ke komo), e hoʻolālā ʻia ka pale pale i hiki ʻole ke hoʻopā ʻia kona mau ʻāpana ola ke kau ʻia ma lalo o nā kūlana maʻamau o ka hoʻohana. Ma waho aʻe o ka hoʻokaʻawale ʻana i ka pale pale i hiki ʻole ke loaʻa, e hoʻolālā ʻia ka mea pale pale i ka wā i hoʻokomo ʻia a hoʻopaʻa ʻia no ka hoʻohana maʻamau, ʻaʻole hiki ke loaʻa nā ʻāpana ola, ʻoiai ma hope o ka wehe ʻana i nā ʻāpana hiki ke wehe ʻia me ka ʻole o nā mea hana. ʻO ka pilina ma waena o ka pahu lepo a me nā ʻāpana āpau e pili ana iā ia he impedance haʻahaʻa. Nānā ʻia ka hoʻokō e nā hoʻokolohua. 2. Ke au i koe (koe ke au) I_PE No nā mea hoʻomalu hoʻoluhi a pau me nā pahu PE, ʻo ka I_PE e ana ʻia me nā pauku a pau o ka mea pale pale i hoʻopili ʻia i ka lako mana o ka reference test voltage (UREF) e like me nā ʻōlelo a ka mea hana. Nānā ʻia ka hoʻokō ʻana e kahi hoʻāʻo, ʻaʻole pili i nā SPD i pili wale iā N-PE. 3. Kiekie pale Voltage i luna ʻO ka volt palena o ka pale pale ʻana should not exceed the voltage protection level specified by the manufacturer. Compliance is checked by tests. 4. Action load test When the maximum continuous working voltage Uc is applied, the pale pale ʻana shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type pale pale ʻana or combined pale pale ʻana shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_SCCR. Nānā ʻia ka hoʻokō e nā hoʻokolohua.
