Ɔkwan bɛn so na wobebu sɛnea aburow a wɔde noa aduan no mu yɛ hyew no sɛe no ho atɛn?
Akwan a wɔfa so bu atɛn wɔ sɛnea aburow a wɔde noa aduan no sɛe no sɛe no ho titiriw ne nea edidi so yi:
1. Fa multimeter susuw resistance value no:
1.1 Fa multimeter no si 200 ohm resistance gyinabea, fa test pen abien ka ɔhyew tube no ano abien no ho, na susuw ne resistance value. mpɛn pii no, dodow a ɔhyew tube no tumi yɛ kɛse no, dodow no ara na ne resistance bo no sua, mpɛn pii no wɔ range of duns of ohms to hundreds of ohms{{4} THE THE UNITER THE THE THE HEATING .
1.2 Nea ɛka ho no, wobetumi abu anyinam ahoɔden a ɛwɔ anyinam ahoɔden afiri no mu no ho atɛn denam susuw a wɔsusuw resistance bo. bere a wɔayɛ anyinam ahoɔden ɔhyew afiri no akyi no, ne bo a ɛko tia no yɛ nea wɔahyɛ da ayɛ, enti wobetumi asusuw anyinam ahoɔden a ɛwɔ ɔhyew afiri no mu no ho denam susuw a wɔsusuw resistance bo no so. .
2. susuw insulation resistance no:
2.1 Fa multimeter no si 2 megohm gyinabea, fa sɔhwɛ kyerɛwdua biako si anyinam ahoɔden ɔhyew afiri no ano biako so, na fa sɔhwɛ kyerɛwdua foforo no ka akyi akorade no ho na fa susuw insulation resistance. sɛ multimeter no kyerɛ megohms bɛboro 2 a, insulation adwumayɛ no ye Sɛ ɛkyerɛ sɛ ennu 0.5 megohms a, ebia ɔhaw bi bɛba wɔ leakage ho .
2.2 Fa insulation resistance measuring susudua di dwuma, fa ewiem baako bata electric heating tube no akyi abon no ho, na ɛde base a ɛwɔ cable anaa terminal no ano baako no susu insulation resistance value. sɛ value no yɛ kɛseɛ a, ɛkyerɛ sɛ insulation performance no ye; Sɛ bo no sua a, ebia insulation no bɛsɛe.
3. Hwɛ sɛnea aburow a wɔde noa aduan no yɛ adwuma:
3.1 Sɛ aburow a wɔde noa aduan no ɔhyew afiri no sɛe a, ebetumi ama ɔhyew no antumi ankɔ adwumayɛ hyew, nsu a ɛnyɛ pɛpɛɛpɛ, plasticization a ɛnyɛ pɛpɛɛpɛ, ɔfasu a ɛyɛ kusuu, nneɛma a enni hɔ bere a wɔde injection no gu mu, ne nea ɛkeka ho.
3.2 Ɔhyew a ɛnteɛ nso yɛ ade titiriw a ɛkyerɛ sɛ ɛyɛ ade a ɛho hia. Fa ɔhyew kyerɛwtohɔ anaa infrared thermometer susuw ɔhyew a ɛwɔ anyinam ahoɔden afiri a ɛma ɔhyew no ani. no ani so sɛ ɔhyew no nyɛ nea ɛfata a, ebetumi akyerɛ sɛ anyinam ahoɔden ɔhyew afiri no yɛ mfomso anaasɛ ɔhaw bi wɔ ɔhyew a wɔhwɛ so no ho.
