Electrostatic Field Detection System
1.Background:
During the construction of infrastructure and real estate, engineering truck may often meet with high voltage overhead line system, which leads to personal injury and property damage, and sometimes even power cutoff accident. AUTOSTAR has developed Electrostatic Field Detection System to solve this problem. When engineering truck installed with this system moves close to overhead transmission line, this system will give out audible warning to remind the operator.
2.Standard Configuration and Specification
Standard Configuration consists of control box, shielded cable, unshielded cable. This system adopts advanced digital DSP processing technology, which can accurately detect power line and electrical radiation. When field density exceeds a set value, the system will alarm. It has good anti-interference ability, and can work in all bad weather conditions.
| Rated Voltage | DC 24V |
| Working Voltage | DC 18V~36V |
| Power | <120mA |
| Working Temperature | -40°C~85°C |
| Sensitivity | -100dB |
| Detection Range | 0~200m |
3.Detection Range
The system can detect various voltage of transmission power line of 220KV, 110KV, 10KV, 380V, 220V, etc. Detection range depends on system trigger adjusting and field density. When set at the lowest , 220kV power line alarm distance can reach 200m, 220V alarm distance can reach 0.5-1m. Therefore, system alarm trigger threshold level needs to be adjusted depending on construction site environment to reach a reasonable alarming distance.Operation Step: (1)Control the engineering truck bar to be close to overhead line till the safe distance and then keep the bar still. (2)Observe the field density indicator light, adjust the knob until it is at the edge of beginning to alarm (3) After adjusting, make sure the knob is not changed.After adjusting trigger and thresholds, engineering truck can work normally. During the process of work, if the bar of the truck gets close to overhead line, control box of this system will give out warning. If the bar gets closer, then the audible waning will be faster.
