1. Ua ntej kev sim, sim cov cable thiab tso tawm hauv av tag nrho; Tshem tawm cov khoom siv txuas nrog rau ob qho kawg ntawm lub cable, thiab tsis muaj lwm yam khoom siv txuas nrog thaum lub sijhawm kuaj; ntxuav lub insulating nto ntawm lub taub hau cable ntawm ob qho kawg kom txo tau cov xau tam sim no los ntawm qhov chaw. Yog tias tsim nyog, insulating baffles yuav tsum tau ntxiv ntawm cov theem ntawm lub taub hau cable.
2. Kev ntsuas kev nyab xeeb yuav tsum raug coj mus rau hauv qhov chaw sim, xws li laj kab, thiab lwm yam. tshwj xeeb, yuav tsum tau muab lub cim ceeb toom rau ntawm lwm qhov kawg ntawm lub cable thiab yuav tsum tau xa ib tus neeg tshwj xeeb los saib xyuas kom tsis txhob muaj cov neeg sab nrauv tuaj txog, thiab xyuas seb cov xaim hauv av thiab cov pas dej tawm puas txuas nrog zoo.
3. Thaum lub zog siab, qhov voltage yuav tsum tau maj mam nce ntxiv kom tsis txhob muaj qhov hluav taws xob tam sim no loj dhau, thiab cov nqi xau tam sim no yuav tsum tau nyeem tom qab nyob ntawm 0.25, 0.5, { {5}}.75, thiab 1.0 zaus qhov ntsuas hluav taws xob rau 1 feeb; Ua qhov ntsuas qhov ntsuas hluav taws xob nyob rau lub sijhawm teev tseg, thiab nyeem tus nqi xau tam sim no tom qab ntsuas qhov ntsuas hluav taws xob ua ntej kawg ntawm qhov ntsuas qhov ntsuas hluav taws xob.
4. Nyob ntawm seb hom cable, lub microammeter muaj cov txheej txheem sib txawv. Feem ntau, lub microammeter txuas nrog rau sab hluav taws xob siab, thiab lub zog hluav taws xob siab thiab lub microammeter yog shielded. Rau cov hluav taws xob cables nrog tooj liab hlau mesh shielding txheej thiab hauv av rwb thaiv tsev, lub microammeter kuj tseem tuaj yeem txuas nrog hauv cov voj voog hauv av ntawm cov kab hauv qab kev sim, thiab kev hloov pauv tau txuas nrog rau qhov sib npaug ntawm ob kawg ntawm microammeter, thiab qhov hloov pauv yog qhib thaum ntsuas. , kaw qhov hloov ua ntej tso tawm tom qab ntsuas kom tsis txhob muaj kev puas tsuaj rau lub microammeter vim qhov cuam tshuam ntawm cov pa tawm tam sim no.
5. Qhov ntsuas hluav taws xob yuav tsum ntsuas ncaj qha rau ntawm qhov hluav taws xob siab. Vim hais tias thaum ib nrab -wave rectification los yog voltage doubler rectification yog siv, yog hais tias tus txheej txheem ntawm converting lub ntsuas voltage nyob rau hauv qis -voltage sab rau voltage ntawm lub siab -voltage sab yog saws , vim yog qhov cuam tshuam ntawm qhov hluav taws xob waveform thiab kev hloov pauv qhov yuam kev thiab qhov tsis txaus ntseeg tam sim no, qhov amplitude ntawm qhov siab -voltage test voltage kuj yuav siab heev. Muaj qhov yuam kev loj, yog li qhov ntsuas hluav taws xob yuav tsum ntsuas ncaj qha rau ntawm qhov siab -voltage sab.
6. After each withstand voltage test is completed, the voltage should be reduced first and the power supply should be cut off. Then, use a current limiting resistor of about 80 kΩ per kV to discharge the cable to the ground several times, and then directly discharge it to the ground. The discharge time should not be less than 5 minutes to ensure full discharge.
