如何理解 SAA 插座 高压测试要求
有没有哪位清楚SAA 插座 高压测试要求，对地线脚的高压测试是多少伏？The socket-outlet shall withstand, without failure, an a.c. voltage of the value indicated in Table 3.3 applied between the parts set out in Items (a) and (c) of Clause 3.14.2 for 1 min in each case. The socket-outlet shall further withstand, without failure, a voltage of 3500 V a.c. applied between the parts set out in Items (b) and (d) of Clause 3.14.2 for 1 min in each case. The socket-outlet shall be fitted with an appropriate plug during the test.
TABLE3.3 TEST VOLTAGES FOR HIGH VOLTAGE TEST
Working voltage (r.m.s.) between parts (See Note) Testing voltage
≤ 32 V 500 V
> 32 V ≤250 V 1 000 V
>250 V ≤650 V 1 000 V + (2 ×working voltage) with a maximum of 2000 V
NOTE: For example, a socket-outlet for connection to a system operating at 415 V between phases and 240 V to earth, would require a test of 1000 + (2 × 415) V between live terminals but a test of only 1000 V between live parts and earth.
3.14.2
d,Between live terminals of the socket-outlet and the earthing terminal (if any), with the live terminals of the plug being connected together. 1000V啊!
with the live terminals of the plug being connected together. d,Between live terminals of the socket-outlet and the earthing terminal (if any), with the live terminals of the plug being connected together. --如何理解？ 火零相联对地打耐压 >>>>Between live terminals of the socket-outlet and the earthing terminal (if any), with the live terminals of the plug being connected together.--测试电压3500VAC
a test of only 1000 V between live parts and earth. -----
测试电压3500VAC
什么意思？？ 引用第1楼小鸭的天空于2009-04-03 12:33发表的:
1000V啊!
with the live terminals of the plug being connected together.
之前的有误, 应是:
1) 对额定电压为250V的: 火零线端子与地端子之间: 3500V
2) 对额定电压为415V的: 火线端子与零线端子之间: 1000+(415x2)V; 火零线端子与地端子之间: 1000V.
