무엇 아르 검출 방법 인덕터

인덕터 검출 방식

(1) The 발현 of 인덕터 손상 include 단락 회로, 개방 회로, etc.

(2) 사용 a 멀티미터 to 결정 품질 의 인덕터.

Method of using a pointer multimeter to detect an inductor: First, set the multimeter to the "R" position in the Ohm range × 1 "gear, with two probes connected to the two pins of the inductor, a fixed resistance value can be measured under normal circumstances. If the needle does not move, it indicates an internal open circuit in the inductor. If the needle indicates a trend towards 0 Ω, it indicates a short circuit inside the inductor; Next, place the multimeter in "R × 10K "gear, detect the insulation condition of the inductor, measure the resistance between the coil lead and the iron core or metal shield, all of which should be infinite, otherwise the insulation of the inductor is poor; Finally, check the structure of the inductor. The coil winding of a good inductor should not be loose or deformed, and the lead out end should be firmly fixed. The magnetic core can rotate flexibly without loosening, otherwise the inductor may be damaged.

방법 for detecting 인덕터 with a digital 멀티미터: 회전 the 범위 스위치 of the 디지털 멀티미터 to the 적절한 인덕턴스 위치; Then connect two 핀 of the 인덕터 with two 프로브 to display 인덕턴스 의 인덕터 on the 디스플레이 화면. If the 표시 인덕턴스 is 유사 to 공칭 인덕턴스, it indicates that the 인덕터 is normal; If the 표시 인덕턴스 differs significantly from the 공칭 value, it indicates that there is a problem with the 인덕터.

(3) Generally, damaged inductors should be replaced with inductors with the same nominal inductance and current.
