IEC 60335-2-9 cl 19.103:
) F6 j+ w8 H9 T! CInduction hotplates are supplied at ratedvoltage and operated with a steel disk placed on the centre of thecooking zone. The disk has a thickness of 6mm and the smallestdiameter, rounded up to the nearest centimetre, which allows theappliance to operate.

做这块钢盘不容易做啊,要选择很多次才对。你们是怎么做的呢。/ T+ B1 W9 P* P# L+ g. i9 N
这个很容易调的,就按照标准做,一般都有准备了好几个看盘的,电磁炉没有钢锅是不会运行的,这个试验的目的就是用最小的钢盘产生涡流使得电磁炉运行,这个情况应该比较恶劣吧 B& @( V' U, M1 i7 J4 c

电磁炉如果标额定功率2000W,实测1600W可以吗?

cl 3.1.9.108
! t# M0 b" y9 h: KInductionhotplates are operated with vessels, as specified in Figure 104,containing cooking oil. Controls are adjusted to their highest settinguntil the oil temperature reaches 180 oC +-4 oC and are then adjustedso that this temperature is maintained. The oil temperature ismeasured  1cm above the centre of the bottom of the vessel.

问题是:0 h0 o- D! O5 l7 [' J% F, A
做正常温升时,如果油温度只有160多度时电磁炉的温度保护了,油温达不到180 oC +-4 oC ,
7 k3 X- O1 n2 E这条怎么判断?
" I. \# \7 X0 c7 o& L6 j9 H" ?油放少一点,如果确实是这中情况,通知客户,如果客户不肯改,就在报告中注明这个情况,一般是客户为了通过试验,调低了温度,出货的时候就不一样了,用来烧菜的锅不可能只有160度的,否者卖不出去的。% N' F0 O! M; f1 M
再检查一下说明书,看看是不是就是用来烧水的,温度这么低 |
