IEC60335-2-64正常温升问题
一个商用榨汁机，就是柑橘果柠檬那种榨汁机，做IEC60335-2-64.按照第3章的说法，要做到过载保护动作。
我这台机器的保护器只有电机上的一个自复位的thermal cut-out。
那是不是要做到这个热保护器动作呢？？那温升岂不是很高？？
第3章的哪个说法？第三章应该是只有定义一节，没有测试要求。 lucky 发表于 2012-9-2 21:50 static/image/common/back.gif

60335-2-64cl.3.1.9
是这个吧：
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions
The appliance is operated without load at rated voltage and with controls intended to be
adjusted by the user set at maximum until steady conditions are established. The appliance is
then loaded in appropriate steps, the supply voltage being maintained at its original value. For
each step, steady conditions have to be established before increasing the load. This operation
is repeated until just before an overload release operates, or until the steady condition with
the highest temperature has been attained.
NOTE 101 The load may be achieved by using an electrical or mechanical brake.
Where it is not possible or is impractical to apply effectively an electrical or mechanical brake,
the load is 115 % of the input measured when the appliance is operated without load at rated
voltage and normal operating temperature, and with controls intended to be adjusted by the
user set at maximum.
NOTE 102 Examples of such appliances are
– liquid blenders;
– slicers;
– peelers;
– coffee grinders;
– machines used for washing and/or drying food;
– portioning machines. lucky 发表于 2012-9-9 19:57 static/image/common/back.gif
