冲击式内燃螺栓扳手电源电路研究与设计

Research and design of power circuit for impact bolt wrench

为实现冲击式内燃螺栓扳手控制器的稳定工作,通过测试发现在汽油发电机和控制器之间会有浪涌出现。并且在实际应用中,电路浪涌干扰会导致控制装置频繁进入保护状态,这严重影响了内燃螺栓扳手的使用。针对以上问题,利用二极管、功率电阻和TVS管等非线性元器件设计了两种电源浪涌软启动抑制电路。通过电路仿真和结合冲击式内燃螺栓扳手做松紧螺栓实验,结果表明,该电路能有效抑制浪涌,而且能够为内燃螺栓扳手提供稳定工作电源。

In order to achieve the stability of the internal combustion bolt wrench controller, this paper found that there was a surge between the gasoline generator and the controller. And in practical applications, the circuit surge interference will lead to frequent access control device into the protection state, which seriously affected the use of internal combustion bolt wrench. In view of the above problems, this paper designs two kinds of power surge soft start suppression circuits by using non-linear components such as diodes, power resistors and TVS tubes. The simulation results show that the circuit can effectively suppress the surge and provide a stable working power for the internal combustion bolt wrench by circuit simulation and the combination of the internal combustion bolt wrench.
