21.2标准条款:
固体绝缘的易触及部件,应有足够的强度防止锋利工具的刺穿。
对绝缘进行下述试验,以确定其是否合格。如果附加绝缘厚度不少于1mm,并且加强绝缘厚度不少于2 mm,则不进行该试验。
绝缘温度上升到在第11章测得的温升。然后,使用坚硬的钢针对绝缘表面进行刮蹭,其针头端部为400的圆锥形,尖端圆周半径为0. 25 mm±0. 02 mm。针头保持在与水平面80°~85°,施加10 N±0.5 N 的轴向力。针头沿绝缘表面以大约20 mm/s的速度滑行,进行刮蹭。要求进行两行平行的刮蹭,其间要保证留有足够的空间不致互相影响。其覆盖长度约达到绝缘总长度的25%。转90°再进行两行与之相似的刮蹭,但它们与前两行刮蹭不可相交。
用图7所示的试验指甲以大约10N 的力于已被刮蹭的表面进行试验,不出现如材料分离之类的进一步损坏。试验后,绝缘应经受住16.3的电气强度试验。
然后,使用坚硬钢针施加一个30N±0.5 N 的垂直力于绝缘表面的一个未刮蹭部位。以该钢针为一个电极对绝缘进行16. 3的电气强度试验。
Accessible parts of solid insulation shall have sufficient strength to prevent penetration by sharp implements.
Compliance is checked by subjecting the insulation to the following test, unless the thickness of supplementary insulation is at least 1 mm and that of reinforced insulation is at least 2 mm.
The insulation is raised to the temperature measured during the test of Clause 11. The surface of the insulation is then scratched by means of a hardened steel pin, the end of which has the form of a cone with an angle of 40°. Its tip is rounded with a radius of 0, 25 mm ± 0, 02 mm. The pin is held at any angle from 80° to 85° to the horizontal and loaded so that the force exerted along its axis is 10 N ± 0, 5 N. The scratches are made by drawing
the pin along the surface of the insulation at a speed of approximately 20 mm/s. Two parallel scratches are made. They are spaced sufficiently apart so that they are not affected by each other, their length covering approximately 25 % of the length of the insulation. Two similar scratches are made at 90° to the first pair without crossing them.
The test fingernail of Figure 7 is then applied to the scratched surface with a force of approximately 10 N. No further damage, such as separation of the material, shall occur. The insulation shall then withstand the electric strength test of 16.3.
The hardened steel pin is then applied perpendicularly with a force of 30 N ± 0,5 N to an unscratched part of the surface. The insulation shall then withstand the electric strength test of 16.3 with the pin still applied and used as one of the electrodes.
