五、CS33V01 VFD按例分析

1.蜂鸣器嘀、嘀、嘀…急促鸣叫: ? 上电延时保护电路故障:

该机型有两处上电延时保护,以右炉QF-450板为例,首先将万用表黑表笔接地IC2(12),另一端置于板IC2(2)脚,再给线路板通电,此时表值显示应为:由15V降至0.1V为时约2秒。若一直为15V,常见为C301、C302、C303、C304等电容漏电或R301、R302、R609大电阻变质或15V电源已损坏。同样步骤测量D601正端压降,电压参数应为1.30V降至0V,为时约2秒,常见故障原因为C602不良或电源15V(C601端压降)部分故障;

? 上述电路正常,可检查耦合电容C801(涤纶2A103J)或微分电容C104(涤纶2A103J)及C102、C103等是否已损坏; ? 电源回路故障:高压主回路(300V)常见故障为滤波器L001、C001、C002、C003虚焊。低压16V供电回路常见故障为Q901不良或低压5V供电回路常见故障为Q202不良。(注:工作数分钟后出现此故障,上述检查步骤同样适用) 3456728R001100K2WSR002100K2WSR003QF-20FR100K2WR004100K2WR005100K2WR006R106100K2W+16V2K2FD101IN4148+5V+16VR807A01C0040.3uF/1K2VDCA02方案一 IGBTRG1.210RJ/0.5WQ803S8050R60722RJ/0.5WC101102R1015K1F8DV2BY459C0033.3uF/400VDCX2BR001GBJ2506RE0210kJR8082K2/0.5WR8022KFC802301JR80410KD8011N4148ZD9055V1/1WQ804S8550R80110KC005+5V12R806100JQ801S9014CC8012A103J149IC2CLM3391032.2K/0.5WR80510KC102101ZC103102C105104ZR1072KC1042A471ZR10982KD102C1071uF/50VR11110KC106100uF/25V1N414811IC2DLM33913R10212KFD3031N4148R1125K6Q802S9014CR60515KR1083K3103+16VL001+20VC803104C80410uFQ601S8050DQ602S8050DZD6015.1V/0.5WC6014.7UF/16VR80310KR104+5VR10310KF3KF10KF+5VR5055K612R50610KC505104Z+5V1234567891011121314CN503IGBT10K6 R602330KR60347KR60415KC602104ZR105R301820K/1W17R110470JC301102K/1KVR302330K/1WR60622KD601IN4148R609510KR61016KC108104Z+5VIC2ALM339D302IN4148D301IN4148R30547KC30310uF/16VIC2BLM339425+16VR30818K+16VAVCC-26VVFF1VFF214R3064K7R30722KQ301S9014C C0022uF/250VAC122T0023D201--204R2013K3IN4148X4D701IN4007C201C103KR20215KJC2024.7uF/50VR30314KC302102JR7051M5R304220KC3041uF/50VT00134R20410KR205R206KKC203104ZR703R20351KJVR1103KBR20743KJ*ZNR110D561K D702IN4007方案二 N2VFF1470K/1WR701R7029K1FC70110uF/16VD905IN4001C908100uF35VQ903A708YR9042K2JC90910uF/50VD903ZD90327V/0.5W-27V47KFR704140KFC702104ZR402Q901D882+16VC91010uF50V24VC0012uF/250VAC15J/2WQ202S8050C+5V21 CN401FAN18VR4012KJQ401S8050DC906100uF16VC907104ZN14.3VACVFF2R902150/1WR9031KZD9025V6/0.5W24V顾客服务部 AC 800-8571477 第 21 页 共 62 页 C902D901R90110uF/25VC904104ZC903470uF/25VC90547uF/16V20VACD902T1FS115A250VD906IN4001N3R90710R/1WD904IN4001X4S8050CC91210uF/50V510J/1W+20VAC901470uF35VZD90116V/1WQ904R905200J/1W右炉234567 浙江苏泊尔家电制造有限公司 方案三 R001100K2WSR003R002R004100K2WSR005100K2WR006R106100K2W+16VQF-20FR100K2W2K2FD101IN4148+5V+16V100K2WR807Q803S8050A01C0040.3uF/1K2VDCDV2BY459C0033.3uF/400VDCX2BR001GBJ2506RE0210kJR8082K2/0.5WC803104A02R60722RJ/0.5WRG1.210RJ/0.5WZD9055V1/1WQ804S85502.2K/0.5WR80510KC101102R1015K1F8IGBTR8022KFC802301JR80410KD8011N4148R80110KC005+5V12R806100JQ801S9014CC8012A103J149IC2CLM339103C102101ZC103102C105104ZR1072KC1042A471ZR10982KC106100uF/25VD1021N414811C1071uF/50VR11110K13IC2DLM339R10212KFD3031N4148R1125K6Q802S9014CR60515KR1083K3103+16VL001+20VC80410uFQ601S8050DQ602S8050DZD6015.1V/0.5WC6014.7UF/16VR80310KR104+5VR10310KF3KF10KF+5VR5055K612R50610KC505104ZE2 +5V1234567891011121314CN503IGBT10K6 R602330KR60347KR60415KC602104ZR105R301820K/1W17R110470JC301102K/1KVR302330K/1WR60622KD601IN4148R609510KR61016KC108104Z+5VIC2ALM339D302IN4148D301IN4148R30547KC30310uF/16VIC2BLM339425+16VR30818K+16VAVCC-26VVFF1VFF214R3064K7R30722KQ301S9014CC0022uF/250VAC122T0023D201--204R2013K3IN4148X4D701IN4007C201C103KR20215KJC2024.7uF/50VR30314KC302102JR7051M5R304220KC3041uF/50VT00134R20410KR205R206KKC203104ZR703R20351KJVR1103KBR20743KJ*ZNR110D561K D702IN4007470K/1WR701R7029K1FN2VFF1C70110uF/16VD905IN4001C908100uF35VQ903A708YR9042K2JC90910uF/50VD903D904IN4001X4S8050CC91210uF/50VC913ZD90327V/0.5W-27V47KFR704140KFC702104ZR402Q901D882+16VC91010uF50V24VC0012uF/250VAC15J/2WQ202S8050C+5V21N14.3VACVFF2R902150/1WR9031KC904104ZZD9025V6/0.5W24VAC20VACD901R901510J/1W+20VAC90210uF/25VC90547uF/16VC906100uF16VCN401FAN18VR4012KJQ401S8050DD902T1FS115A250VD906IN4001N3C911470uF35V220VinLNR90710R/1WC901470uF35VZD90116V/1WQ904R905200J/1WC903470uF/25VC907104ZZD90420V/0.5W470uF/25VC914104ZR9066.8KJ右炉 顾客服务部 800-8571477 第 22 页 共 62 页 234567 浙江苏泊尔家电制造有限公司
