插头电源线组件工厂例行测试要求详解

带插头和尾插或连接器的插头电源线，习惯叫延长线，电源线组件等，专业术语叫Cord Set（电线组件）。作为电气连接安全产品，必须要有电气强度测试（耐压测试），几个样品我们可以放到实验室依插头或连接器标准测试。但是，批量生产如何进行例行测试，打多少高压，测试时间有标准依据吗，如果一次测试时间为60S(1分钟)的时间等不起。这个问题一直有厂家，购买商在咨询这些问题，今天，安规仪器网工程师就电线组件的例行测试作详细地解释.特别说明。

注意：此标准要求仅适用于采用IEC标准之国家。不适用于北美，台湾，日本标准等电源线。

依据标准

IEC/EN 60799-1998, GB15934-2008

ELECTRICAL ACCESSORIES--CORD SETS AND INTERCONNECTION CORD SETS.

Annex A：Routine tests for factory-wired cord sets and interconnection cord sets related to safety (protection against electric shock and correct polarity)

GB15934-2008 电气附件. 电线组件和互联电线组件(等同采用IEC/EN 60799)

附录A：工厂接线的电线组件和互连电线组件安全性例行试验（防触电保护和正确极性）

适用类型:

A.1 General

All factory-wired cord sets and interconnection cord sets shall be subjected to the following tests, as appropriate.

Table at the Annex A for the IEC/EN 60799-1998

A.1 附录1

适用时，所有工厂接线的电线组件和互连电线组件应经受下列试验。

两极或三极的电线组件和互连电线组件，也就是两个插销的和三个插销的电源线组件（头+尾）的都要测试。

A.2 Polarized systems; phase (L) and neutral (N) – Correct connection

A.2 极性系统；L极/相线和N极/中线---正确连接

For polarized systems the test shall be made using safety extra-low voltage SELV applied for a period of not less than 2 s between the L and N pin or contact and the corresponding L and N pin or contact at each end of the cord set or interconnection cord set.

NOTE – The period of 2 s may be reduced to not less than 1 s on test equipment with automatic timing.

Other suitable tests may be used.

Polarity shall be correct.

A.3 Earth (E) continuity

A.3 E极/接地连续性

The test shall be made using SELV applied for a period of not less than 2 s between the corresponding E pin or contact of the accessory at each end of the cord set or interconnection

cord set.

NOTE – The period of 2 s may be reduced to not less than 1 s on test equipment with automatic timing.

Other suitable tests may be used.

Continuity shall be present.

A.4 Short circuit/wrong connection and reduction in creepage distance and clearance L or N to E

A.4 短路/错接和L极或N极与E极的爬电距离和间隙的减少

The test shall be made between the L and N conductors and the E conductor

– by applying at the supply end, i.e. plug, an a.c. voltage of 2 000 V ± 200 V, 50 Hz or 60 Hz

for a period of not less than 2 s,

NOTE – The period of 2 s may be reduced to not less than 1 s on test equipment with automatic timing.

or

– by an impulse voltage test using 1,2/50 µs wave form, 4 kV peak value, three impulses for

each pole, with intervals of not less than 1 s, the test voltage being applied at the supply

end, i.e. plug or plug connector.

The L and N conductors may be connected together for this test.

No flashover shall occur.
