我的amplifier和fmreceiver,当我去开或关的时候,我一直被电到哦,是不是静电来得啊?
要如何解决啊?
很怕给它电傻掉噢,
哪位大大可以帮我啊?
感恩! |

很多时候amplifier都有电的..
如果你觉得身体很多静电....那么你需要睡多一点...或者早睡....喝多一点水.... |

用一条电线,贴在/绑在/粘在 amp上有铁的部分(或者用机壳上面的螺丝绑住),然后进ground,应该就没有问题了。 |

满好笑的。。。。
所有Audio / Video home entertainment system (metal 的外壳)。。 2pin plug 的都会有这个问题。。。leagake current 大或者小。。有spec 的。。。
discharge 那静电就没事了。。。
下一轮有机会及时间。。会进一步解释。。。
[size=-1]Leakage current is the current that flows from the unit through the grounding conductor into a household ground. Leakage current could shock an individual if the household grounding is not sufficient or there is an intentional or unintentional interruption of grounding connection.
[size=-1]Leakage current of 3 milliamps through the heart would create a mild shock and some pain ; 8 milliamps would cause an interruption in heart function (cardiac arrhythmia) which could eventually kill a healthy person in seconds.
[size=-1]Note: the requirement for medical equipment however is more stringent; a fatal shock could result if the patient is in a weak or unconscious condition.
[size=-1][size=-1]CLASS I EQUIPMENT[size=-1]: Equipment where protection against electric shock is achieved with the combination of basic insulation and protective earth ground connect to case.
[size=-1][size=-1]CLASS II EQUIPMENT[size=-1]: Due to the fact that there is no protective earth ground in the equipment, the protection against electric shock relies on double insulation or reinforced insulation.
[size=-1][size=-1]CLASS III EQUIPMENT[size=-1]: Equipment in which protection relies upon supply source from SELV circuits and in which hazardous voltages are not generated.
[size=-1][size=-1]PATIENT AUXILIARY CURRENT[size=-1]: Current flowing in the patient in normal use between parts of the applied part and not intended to produce a physiological effect; for example, bias current of an amplifier or current used in impedance plethysmography.
[size=-1][size=-1]PATIENT LEAKAGE CURRENT[size=-1]: Current flowing from the applied part via the patient to the ground or flowing from the patient via an F-type applied partially to the ground, originating for the unintended appearance of a voltage from an external source on the patient.
[size=-1]Requirement
[size=-1]For Information Technology Equipment ([size=-1]I.T.E[size=-1].[size=-1])
[size=-1][size=-1][size=-2]Classification
| [size=-1][size=-2]Maximum Leakage Current
| [size=-1][size=-2]Class I
| [size=-1][size=-2]0.75mA (Hand held equipment)
| [size=-1][size=-2]3.5mA (All others)
| [size=-1][size=-2]Class II
| [size=-1][size=-2]0.25mA
| [size=-1][size=-1]For [size=-1]Medical[size=-1] Equipment
[size=-1][size=-1][size=-2]Current
| [size=-1][size=-2]Normal Condition
| [size=-1][size=-2]Single Fault Condition
| [size=-1][size=-2]Earth Leakage Current
| [size=-1][size=-2]0.5mA
| [size=-1][size=-2]1mA
| [size=-1][size=-1]Other than the medical leakage current requirement mentioned above, there are other leakage current requirements in [size=-1]IEC 601-1[size=-1](Medical), such as patient leakage current, patient auxiliary current and enclosure leakage current. (We will not discuss these topics as they do not apply to our power supplies.)
[size=-1]For [size=-1]Class 2[size=-1] Equipment
[size=-1][size=-1][size=-2]Type of Equipment
| [size=-1][size=-2]Maximum Leakage Current
| [size=-1][size=-2]Portable Unit
| [size=-1][size=-2]0.5mA
| [size=-1][size=-2]Stationary Unit
| [size=-1][size=-2]0.75mA

看过很多报道~说amplifier从interconnect去ground声音会更好听。。。有没有资料。 |

回复 6# needforsleep 的帖子
等我整理一下我的资料。。then 大家再来研究一下。。。。
刚回到家。。因为最近比较忙。。。起码都要到下个礼拜才得空。。。
这个礼拜有很多问题需要solve。。especially ESD issue。。。
被老板tekan 到很够力。。。 |

哦,意思就是讲,拿一条电线,连在 amplifier 或其他的电器上面,然后接到底线上哦,
不会有事的吧?我的 fm receiver 是用 2pin cable 的。
我怕被电到飞起来耶,明天上头条,“安装电器被电到飞起”, 呵呵 |

另外用一个新插头只接地线。。。其他的两个线不要接,fuse没有用到,拿出来。
给vvazn说到我也怕你出事。 |

小心有些接了反而会炸毁你心爱的电器,我之前买了一支焊接器,2pin plug,会电人的哦!接了地线后, 当我开电时,啪!一声,喷火花,就这样坏了。 |
