Switches Intended for Self-ballasted Lamp Loads Automatic Breaking Capacity Test System

Automatic Breaking Capacity Test System for Switches Intended for Self-ballasted Lamp Loads

Standards & Clauses:

This system is designed and manufactured according to the standard of IEC 60669-1:2017 clause 19.3 and IEC 60669-2-1:2015 clause 19.109. It is a fully automatic test system based on the test readability of a switch with a rated voltage of 250V, including an intelligent industrial control system (built-in oscilloscope), a switch endurance test machine, and a self-ballasted lamp load cabinet. (The switch with rated voltage of 130V needs to be separately configured with self-ballasted lamp load box).

Samples and Restrictions:

Switches intended for self ballasted lamp loads

Application:

This device is suitable for breaking capacity and normal operation life test of switches intended for self ballasted lamp loads. Switches intended for self ballasted lamp (SBL) loads shall withstand, without excessive wear or other harmful effect, the electrical and thermal stresses occurring when controlling self ballasted lamp circuits. To verify whether the switch has sustained arcing nor welding of the contacts occur, any contacts adhesion phenomenon or long term closure or disconnection phenomenon, to test whether excessive wear or other harmful consequences.

Test Principle:

IEC60669-1:2017 and IEC60669-2-1:2015, only for switches with a rated voltage of 250V.

The load box circuit shall be in accordance with Figure 12b and clause19.3, with rectifier bridge and capacitor.

The value of R2 and C in load B shall be chosen in order reach the values (±5%) for I peak and I2t as given in the Table 19 when the switching contact closes at 90°±5° phase-angle. The value of R4 shall be chosen to reach current in amperes to reach the corresponding SBL power as given in Table 19.

The value of R2 and C in load B shall be chosen’ mean that the resistance R3 and the capacitor C is adjustable;
Values (±5%) for I peak and I2t as given in the Table 19 when the switching contact closes at 90°±5° phase-angle’ mean that the integral of the calibration I peak and I2t is obtained at the 90 ° closing, and the equipment must have a 90 ° closing control. The 90 ° closing control does not work during normal testing, and the on/off of the switch is turned on at a random phase angle as in daily operation;
‘The value of R4 shall be chosen to reach current in amperes to reach the corresponding SBL power’ mean that this rated current is not the rated current of the switch, but the corresponding power of Table 2.
