1. 测试方法:

Test procedure:

1) 应选择接线端子上有可能导致最高温度的位置进行温度测量。测试应该持续4个小时即使温度在短时间内达到稳定。达到稳定状态是指三个连续5分钟时间间隔,温度没有进一步上升。

Temperatures shall be measured on the wiring terminals of the pole location judged most likely to result in the

highest temperatures. The test is to continue for 4 hours even if stabilized temperatures are attained in a shorter

period of time. A temperature is considered to be stabilized when three consecutive readings, taken at 5 minute

intervals, indicate no further rise above the ambient temperature.

2) 所有触点应串联使得通过相同电流,电流为 DC2.0A 。

All contacts are to be connected in series so as to carry the same test current, the input is DC2.0A .

3) 测试应该在无空气对流环境温度范围为25 ±5°C (77 ±9°F)的条件下进行。测试在25°C以外的环境温度下得到的结果,应通过增加测试的环境温度与25°C之间的偏差,调整到环境温度为25°C。

This test is to be made in a draft-free area having an ambient temperature of 25 ±5°C (77 ±9°F).

Tests conducted at an ambient temperature other than 25°C are to have the test results adjusted to an ambient

temperature of 25°C by adding the appropriate variation between 25°C and the ambient.

4) 样品每个触点的温升不能超过规定的30℃。

5)

Each contact of the specimen must not exceed the specified temperature rise of 30 ℃.
