Equipment Overview
Test purpose: The remote control high-current short-circuit device is designed based on the requirements of various battery short-circuit test standards. The short-circuit device must meet the internal resistance range of <5mΩ, so as to obtain the maximum short-circuit current required by the test.
Design overview: The circuit design of the short-circuit device must also be able to withstand the impact of large currents, so we will choose industrial-grade DC electromagnetic contactors, all-copper terminals and internal copper plate diversion, and the built-in active ball axial flow fan provides effective heat dissipation protection, which will make the high-current short-circuit device is safer, effectively reduces the loss of the test equipment, and ensures the accuracy of the test data.

| Features | PLC has high operability. It has the characteristics of simple programming, convenient operation, easy maintenance, etc., and is generally not prone to operating errors. The operation of PLC includes the operation of program input and program change. The input of the program can be directly displayed, and the operation of changing the program can also directly follow the required address number or contact number to search or search for the program, and then make changes. PLCs are available in a variety of programming languages. Used for ladder diagram and electrical schematic diagram is closer. The PLC has a self-diagnostic function, which reduces the requirements for maintenance skills of maintenance personnel. When the system fails, maintenance personnel can quickly find the fault location through hardware and software self-diagnosis. |

| Exhaust system | Independent control, when the test sample produces smoke, the equipment can automatically detect and discharge the smoke through the pipeline
|
| Automatic explosion-proof pressure relief system | It has an exhaust function, that is, a large amount of exhaust gas generated in the test is discharged to the outside; it has an explosion-proof pressure relief function, that is, there is a magnet adsorption pressure relief door (specification: 300*300mm) at the rear of the protective box. When the strong airflow impacts, the pressure relief The door opens automatically, reducing the impact of the explosion. |
| Around the explosion-proof box | Equipped with a pressure relief hole, the pressure can be released in time |
| Door of box | It is fixed by high-strength hinges, and at least 3 sets of explosion-proof locks can be installed on the door to be fixed. |
| Principle of explosion-proof box | The double-layer explosion-proof pressure relief structure is adopted, and the pressure relief holes of the inner layer and the outer layer are dislocated and separated, which plays a buffering effect and avoids the ejection of explosive fragments, which plays a role in safety protection. |
| Fire extinguishing device | The explosion-proof box is equipped with a fire extinguishing device. Once the battery explodes, the fire can be extinguished by remote control, and the fire extinguishing device and system can be opened by remote control. |

| Explosion-proof door design | The front door of the test box adopts a reinforced design, which can effectively isolate the damage caused by fire and explosion during the test. The door panel adopts a double-layer design with a mezzanine, and the hinge and door lock adopt reinforced equipment-specific standard parts. The window on the door adopts a double-layer explosion-proof design (the inner layer of anti-projectile mesh). The explosion-proof door is equipped with an explosion-proof lock, and an explosion-proof chain is installed on the explosion-proof door for double protection. |
