被试外壳置于支撑台上，被试外壳在四个倾斜的固定位置各试验2.5min，

The housing is again placed on the support table, each of the test subjects of the housing in four fixed positions 2.5min inclined, the four positions in a plane perpendicular to the vertical of each inclined 15 °, the entire test device in the housing surface generating a uniform flow, the water flow rate of 3.00 + 0.05mm / min. The total test duration 10min. <br>Check whether the housing inlet after the trial, if the water, water does not accumulate in the lead may cause creepage distances along the insulating member is tracking; water is not accumulated in the vicinity of the head or the cable into the cable; water enters the charging member, or into the winding operation in a wet state is not allowed; the amount of water is insufficient to affect normal operation of the device and the security breach.

被试外壳置于支撑台上，被试外壳在四个倾斜的固定位置各试验2.5min，这四个位置在相互垂直的平面上与垂线各倾斜15°，试验用设备在外壳整个面上产生均匀水流，水流量为3.00+0.05mm/min。试验总持续时间为10min。<br>试后应检查外壳是否进水，如果进水，水不积聚在可能导致沿爬电距离引起漏电起痕的绝缘部件上；水不积聚在电缆头附近或进入电缆；水不进入带电部件，或进入不允许在潮湿状态下运行的绕组；进水量不足以影响设备的正常操作以及破坏安全性。

The test shell is placed on the support platform, and the test shell is tested for 2.5min at four inclined fixed positions, each of which is inclined to the vertical line by 15 ° on the mutually perpendicular plane. The test equipment produces uniform water flow on the whole surface of the shell, and the water flow is 3.00 + 0.05mm/min. The total duration of the test was 10min.<br>After the test, check whether there is water in the shell. If there is water, the water will not accumulate on the insulated parts which may cause leakage and trace along the creepage distance; the water will not accumulate near the cable head or enter the cable; the water will not enter the live parts or the winding which is not allowed to operate in the wet state; the water inflow is not enough to affect the normal operation of the equipment and damage the safety.
