Socket Outlet Maximum and Minimum Withdrawal Force Testing Equipment

Maximum and minimum withdrawal force testing equipment is designed according to IEC60884 figure 18/19 and VDE0620, it is applied to evaluate the maximum and minimum pull-out force of the socket. The apparatus is suitable for plugs and sockets with rated voltage not exceeding 250V and rated current less than 16A. The test plugs made of hardened steel with roughness not exceeding 0.8mm.

This device is composed of the clamping device under the mounting plate A, the principal weight F, the supplementary weight G and the test plug C.

Maximum withdrawal force: apply the maximum withdrawal force specified in the standard (the total force of the principal weight, the supplementary weight, the hook (clamping device), and the test plug) to the test plug(multi-pin gauge), and the plug should come out of the socket.

Minimum withdrawal force: insert the gauge (single pin gauge) of the minimum withdrawal force specified in the standard ( the total mass of the pin should be equal to the value specified in the standard) into each individual hole in the socket, in this case, the gauge shall not come out of the socket within 30 seconds.

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...
