IEC60947-1 2 Rpm 500mm IEC Test Equipment

10 Rpm ± 2 Rpm IEC Test Equipment Flexion Test Apparatus For Conductors Height 250~500mm Bushing Within 15mm

Standard:
IEC 60947-1 ' Low-voltage switchgear and controlgear –Part 1: General rules ' clause 8.2.4.3, figure 1

Standard description:

The test is to be carried out with suitable test equipment. The specified number of conductors shall be connected to the terminal. The length of the test conductors should be 75 mm longer than the height H specified in Table 5. The clamping screws shall be tightened with a torque in accordance with Table 4 or with the torque specified by the manufacturer. The device tested shall be secured as shown in Figure 1 .

Each conductor is subjected to circular motions according to the following procedure:

The end of the conductor under test shall be passed through an appropriate size bushing in a platen positioned at a height H below the equipment terminal, as given in Table 5. The other conductors shall be bent in order not to influence the result of the test. The bushing shall be positioned in the horizontal platen concentric with the conductor. The bushing shall be moved so that its centreline describes a circle of 75 mm diameter about its centre in the horizontal plane at 1 0 rpm ± 2 rpm. The distance between the mouth of the terminal and the upper surface of the bushing shall be within 1 5 mm of the height H in Table 5. The bushing is to be lubricated to prevent binding, twisting or rotation of the insulated conductor. A mass as specified in Table 5 is to be suspended from the end of the conductor. The test shall consist of 135 continuous revolutions.

During the test, the conductor shall neither slip out of the terminal nor break near the clamping unit.

Application:
It is used for judging whether the design and the structure of the clamping screw terminal is correspondent with the requirement of non over-damage to the wire. Besides, it is also used to check whether the clamping screw terminal can bear the stress during the process of normal usage.
