A stepping voltage somatosensory device is a device that can simulate the stepping voltage experienced by the human body when walking on the ground. This device helps workers better understand and master the principle and application of step voltage.
Step voltage refers to the damage to the human body caused by the current generated by the voltage difference between the two feet between two different potential points on the ground, when the human body steps from one potential point to another. This injury is mainly caused by thermal, chemical, and mechanical effects when an electric current passes through the human body. The degree of injury to the human body by step voltage is related to factors such as voltage difference, current intensity, area and time of human contact with the ground.
The step voltage somatometric device is mainly composed of the following parts:
1.Power module: provides stable voltage and current for the entire unit. The power module can be AC or DC and can be adjusted according to actual needs.
2.Electrode module: includes ground electrode and high-voltage electrode. The ground electrode is used to simulate one potential point on the ground, and the high-voltage electrode is used to simulate another potential point on the ground. The electrode module can be made of sheet metal, conductive rubber, or other conductive materials for easy human access.
3.Current measurement module: used to monitor the magnitude of the current flowing through the human body in real time. Current measurement modules can employ Hall sensors, electromagnetic sensors, or other current sensing devices.
4.Control system: responsible for controlling the working state of the whole device, including the opening and closing of the power module, the high-voltage output and grounding output of the electrode module, etc. The control system can be a microcontroller, programmable logic controller (PLC), or other control devices.
5.Display module: used to display current, voltage and other parameters, convenient for users to observe and analyze. The display module can use a liquid crystal display, a digital tube or other display devices.
When using a stepping voltage somatosensory device, the user needs to put one foot on the ground electrode and the other foot on the high-voltage electrode, and then slowly move the foot to feel the impact of the stepping voltage on the human body. In this way, the experiencer can better understand the principle and application of step voltage, and provide strong support for safety precautions in practical work.
