3 Pin 2.8mm 23A Straight HVIL Socket High Voltage Interlock Connector Plastic Shell A Key

High-voltage interlock (hvil for short), a safe design method that uses low-voltage signals to manage high-voltage circuits. In the high-voltage system design, in order to avoid the arcing caused by the high-voltage connector being opened and closed during the actual operation, the high-voltage connector should generally have the “high-voltage interlock” function.

High-voltage interlocks are often used in high-voltage electrical circuits, such as high-voltage connectors, msds, and high-voltage power distribution boxes.

The connector with high-voltage interlock can be disconnected by the logic sequence of the high-voltage interlock when it is unlocked when the power is on. the disconnection time is related to the difference in the effective contact length between the high-voltage interlock terminal and the power terminal. it is related to the speed when disconnected.

Under normal circumstances, the response time of the system to the interlock terminal circuit is between 10 and 100ms. when the disconnection (unplugging) time of the connected system is less than the system response time, there will be a safety risk of live plugging and unplugging, and the second unlocking is in order to solve this disconnection time problem, under normal circumstances, the secondary unlocking can effectively control the disconnection time above 1s to ensure safe operation.
