Hemm ġeneralment tlieta raġunijiet għaliex an arja swiċċ vjaġġi. Short circuit, tagħbija żejda u malfunzjonament.
Hemm le ħtieġa biex miżura il qasir ċirkwit , u hemm se be ovvju jew anke enormi acousto-optical phenomena. Għal tripping ikkawżat minn dan raġuni , just eliminat il - kawża il qasir ċirkwit u imbagħad iċċekkja jekk il- kuntatti ta ' l- ... arja swiċċ ġew maħruqa minn iċ-ċirkwit qasir kurrenti. Skonnettja il - superjuri qawwa provvista hekk li l-arja swiċċ hija fi an assolutament mhux enerġizzat stat. Agħlaq l-arja swiċċ u użu l-ohm range of a multimeter to measure the 3fażi il miżura it it tliet fażijiet deħlin u ħerġin wajer terminals ta' l-iswiċċ. Jekk il kontinwità is tajjeb, tista' power on and try it out. If the phase is missing, needless to say, replace the air switch.
Jekk a short circuit occurs in the air switch, the terminals may be broken down. You can use a megger to measure the insulation resistance between the terminals (you can also use a multimeter with a range of 20K or above to measure it. Remove the insulators on sides of the air switch. wires and out wires). If il pointer of the rocker quickly deflects to the right as soon as you start shaking the watch, it means that the phase insulation of the air switch been broken down and cannot be used. If the insulation resistance is very large, several megohms or more, can power on and try it out.
The power-on trial procedure is as mentioned above. Disconnect the front-end power supply, close the repaired air switch, and then close the front-end power switch. If the power supply is normal and there are no abnormal sounds or smells, the air switch can continue to be used. .
tagħbija żejda. Tagħbija żejda hija waħda ta ' ir-raġunijiet għal frekwenti arja swiċċ tripping. Jekk int tmiss it-tagħbija żejda tripped arja swiċċ bi tiegħek id , int se normalment tħoss li il-qoxra hija sħun % 2c anke sħun għal it-touch Dan se jikkawża l-element termali ġewwa l- arja swiċċ għal ħu protettiv azzjoni.
Malfunzjonament. Meta il-bokka u ħruġ wajers ta' l-arja swiċċ huma aluminju wajers, huma huma suxxettibbli għal ossidazzjoni reazzjonijiet ma ir-ram terminals ta' l-arja swiċċ, causing heat at the terminals. The terminals. The thermal protection device inside the air switch is deformed by heat, causing protective action. This is a tipical malfunction. This problem can be solved by pressing copper-aluminum terminals on the aluminum wires and tightly combining them bi l - arja swiċċ terminals.
