Multimeter mezi metòd pou detekte fused rezistans
Fusing rezistans se yon espesyal konpozan ak dual fonksyon resistor ak fuse. Li reprezante pa lèt yo 22RF" oswa "R"R" nan sikwi a .
Selection of Fusing Rezistans
Lè chwazi, dual pèfòmans ta dwe konsidere kòm, ak paramèt tankou rezistans chwazi dapre espesifik kondisyon a sikwi a Li is nesesite asire ke li ka byen vit fuse lè Twò chaje ak, asire ke jo travay stably tan anba nòmal kondisyon. Twòp rezistans oswa pa ka bay pwoteksyon.
Multimeter mezi metòd pou detekte fused rezistans
In a circuit, when the fuse is open, judgment can be made based on experience: if the surface of the fuse resistor is found to be black or burnt, it can be concluded that its load is too heavy, and the current passing through it exceeds the rated value many times; If there are no traces on its surface and there is an open circuit, it indicates that the current flowing is just equal to or slightly greater than its rated fuse value. For the judgment of the quality of a fused resistor without any trace on the surface, a multimeter can be used × To ensure accurate measurement, one end of the fuse resistor should be soldered off the circuit in gear 1. If the measured resistance value is infinite, it indicates that the fused resistor has failed and is open circuit. If the measured resistance value differs significantly from the nominal value, it indicates that the resistance has changed and should not be used again. In maintenance practice, it has been found that there are also a few fuse resistors that are broken down and short circuited in the circuit, and attention should also be paid during testing.
Classification of Fusing Rezistans
Fusing rezistans divize nan de de kalite: rekiperasyon fuse resistors ak dispoze fuse rezistans.
（1） Recoverable Fusing Resistor
Rekiperasyon fuse rezistans yo òdinè rezistans (oswa rezistans fil) ke yo soude nan seri ak low fonn point solder ak prentan type metal rapò (oswa elastik metal metal fèy)"2c ak Lè sa a, sele a silendrik oswa kare Gen gen plizyè kalite nan kokiy, ki gen ladan metal ak transparan plastik.
（2） Disposable fuse resistor
A jetab fuse rezistans 2c li te ye kòm yon ireparab fuse resistor, acts a fix rezistans pandan nòmal sikwi operasyon. Lè li yo opere li yo depase rated rated aktyèl la rated 2c 2c fuse rezistans pral fuse yon fuse pwoteje sikwi a yon dispoze fuse rezistans rezistans li repare repare nan alè manner ka ranplase ranplase fuse rezistans rezistans. Disposable fuse rezistans be divize fil blesi fuse rezistans ak manbrrane fuse rezistans ki baze sou materyèl yo itilize rezistans kò.
1. Fil Wire fuse rezistans yo type type glaz rezistans ak ti rezistans valè ak yo tipikman itilize nan sikwi opere opere aktyèl.
Pandan pwodiksyon pwosesis la pouvwa glaz rezistans bund wire wire oswa ekspoze (san enamel pwoteksyon kouch). evènman an nan evènman evènman fòt nan pwoteje sikwi thin wire oswa ekspoze (san yo pa glaze rezistans burn off overheating, bay pwoteksyon pou sikwi a sikwi a sikwi a sikwi a.
2. Membrane fuse resistors are currently the most commonly used fuse resistors, which are divided into various types such as carbon film fuse resistors, metal film fuse resistors, and metal oxide film fuse resistors.
