IS/ IEC 60947 (Part 2) compliant ACB Test Bench

ACB (Air Circuit Breaker) Test Bench is a PC based Test Bench having lot of facilities like Unique Barcode, Data Logging, Graph and much more.

ACB Test Bench is a one stop solution for various important parameters of ACB (Air Circuit Breaker).

ACB Test Bench consists of following

Continuity Test on Main poles and Auxilliary poles for set number of operations (charging, closing, tripping)
Coil currents of Motor, Closing coil, Tripping, coil, Under voltage coil
Motor charging time
ACB Force Stroke Testing/ Plotter
ACB Lay Shaft Speed Measurement and Testing/ Plotter
ACB Energy Margin Test of mechanism

Salient Features -

PC Based Test Bench
Unique Barcode to each ACB
Data Logging i.e. Test Results are stored in PC against unique barcode
IS/ IEC 60947 (Part 2) compliant ACB Test Bench

Continuity Test -

ACB is operated (charged, closed, tripped) for set number of operations and its continuity on Main poles and Auxilliary poles is taken as feedback to ensure correct functionning of ACB.

Motor Charging Current and Time -

ACB Motor charging current and VA rating is measured along with its charging time. These parameters are logged in Test Bench and also compared with set band to decide pass/ fail.

ACB Force Stroke Measurement/ ACB Force Stroke Plotter -

ACB Test Bench Manufacturer Exporter Force Stroke Tool

ACB Test Bench Manufacturer Exporter Force Stroke Graph

These are Force Stroke tools which are to be mounted on ACB Top plate. It consists of Force sensor with a robotic pusher at constant speed.

System shows distance from Top plate to button, Button travel, Button Over travel, Total travel from Top plate, Peak force of required to press the button and more...

System plots the graph of Force (Y axis) vs. Stroke (X axis). User can export this graph and its related data in excel file.

ACB Lay Shaft Speed Measurement/ Characteristic Plotter -

ACB Test Bench Manufacturer Exporter Lay Shaft Tool

ACB Test Bench Manufacturer Exporter Lay Shaft Speed Graph

The tool is connected to ACB Lay Shaft. It consists of transducers which convert angular speed to digital value.

System shows the Speed of Lay shaft in degrees/ mS and also plots the graph of Shaft Position (Y axis) vs. Time (X axis). User can export this graph and its related data in excel file.

Many times, Moving contact bounces but those bounces are not reflected in electrical continuity but they are certainly caught here and shows the ACB functionality in a totally different perspective.

Energy Margin -

ACB is having a mechanism with motor and spring. When this mechanism is charged, it is supposed to have enough energy stored in order to trip the breaker.

But what is the actual energy required to trip the breaker ? and how much is the energy stored in the mechanism ? Is it sufficiently high ? or just marginal ?

If the energy stored in the ACB is just marginally higher than the actual required, then on the fiield situation may arise that mechanism is not capable to trip the breaker. To analyze such issues, knowing Energy Margin in ACB Mechanism is important.

And our ACB Test Bench is the solution for it.
