The SCR Elektroniks 3 station Socket Endurance Test Bench is designed to verify the endurance testing of sockets as per IEC 60884, IS 1293 and BS 1363. Typical sockets ratings covered are for the entire range (typically 6 – 32 A) for both 3 phase and single phase loads. The tests included (that can be customized) are as follows:
1. Normal Operation (Referred to as Cl 21 in IEC 60884, Cl 21 in IS 1293 and Cl 18 in BS 1363) 2. Making and Breaking Capacity (Referred to as Cl 20 in IEC 60884, Cl 20 in IS 1293 and Cl 17 in BS 1363) 2. Making and Breaking Capacity (Referred to as Cl 20 in IEC 60884, Cl 20 in IS 1293 and Cl 17 in BS 1363)Stand-alone unit after initial configuration of test parameters: The panel is capable to generate accurate test results even after days of continuous operation with no loss of data.
Single / Three Phase operation possible
Servo controlled mechanism to control current (+/- 1%) against incoming fluctuations
CT range selection for current measurement accuracy
Load selection is selector switch based: Quick and easy
PLC based timer unit (Siemens Logo) for quick and easy user interface and automated operation: Easy setting of parameters such as on time, off time, no. of cycles and threshold consecutive contact weld, contact open cycles
Accurately designed iron core inductors (Optional air core inductors as per customer specifications) for circuit parameter accuracy
Specially designed fixture for safe operation with operator safety in view
Cooling shall be provided by means of optimally placed Exhaust fans distributed all over to remove the hot air generated inside the panel cabinet.
This avoids change in circuit parameters as a result of over heating of loads
Ceramic core wire wound resistors with enamel coating: This ensures best quality of resistors that have a favourable resistance v/s temperature rise graph enabling operation for an elongated duration with accuracy
Temperature rise test can be integrated with the main endurance test
PC based option available: Complete PC data logging and control plus online plotting of temperature rise graphs
Total Voltage and current range of the source: 200-270 V , 6-40 A AC (Depending upon the socket ratings selected)
Load Current options: 6, 10, 13, 15 16, 20, 25, 32Amp for Normal Operation and 1.25 times 6, 10, 13, 15 16, 20, 25, 32Amp for Making-Breaking Rated Voltage Options: 220 V, 230 V, 240 V and 250 V (As per user specifications)
Rated Voltage Options: 220 V, 230 V, 240 V and 250 V (As per user specifications)
Power Factor: 0.3 for Breaking Capacity and 0.6 for Normal Operation
User Specified Number of Phases: 3 phase or 1 Phase
For temperature rise test: k type Cr / Al thermocouples with upto 12 temperature channels (customizable) per phase
50 / 60 Hz operation as per incoming line frequency
Pneumatic Pressure: approximately 8 bar
Class 1 Accuracy (for current and voltage display)
The number of stations, discrete current ratingd, PLC / microcontroller / PC based, tests as per BIS, IEC, BS, etc. can be customized. The system can also be clubbed with switch endurance bench wherein the source and load are common, thus giving a economical solution. The fixtures are designed exactly as per the customer samples.
The product is used to test the endurance of sockets when subjected to repititive strokes with an inductive load at the output. The product also identifies the number of cycles it withstands before 'contact open' or 'contact weld' condition is detected thus giving an exact quality assesment of the switch under test. The customer can even test its own and competitor's product and compare the performance
