Crane, excavator, dump trucks and other large engineering vehicles with a huge operating radius and large volume, can be quickly completed in various projects in the material lifting, building construction and other tasks, however, these large-scale engineering vehicles in the convenience of the same time, but also hides a huge security risks, which with the high-voltage lines "contact"! The electrocution accident, as if hanging over the head of the Sword of Damocles", always threatening the safety of people's lives and property.
The fatal mechanism of high-voltage electrocution accidents lies in the high-voltage lines (especially more than 10kV) around the existence of a strong electric field, such as the metal arm of the vehicle such as the "conductor" across the safety distance, even if not in direct contact with the air may also be due to air breakdown leading to a discharge. Different voltage levels of the safety distance is different, for example, 220kV need to be away from 10 meters away, once the breakthrough of such "invisible red line", the current is likely to be conducted through the vehicle, triggering an arc, fire, electric shock.
Carriages are too high, poor visibility at night construction, misjudging the distance, busy construction without observing the surrounding environment ... These are common factors that lead to electrocution of vehicles near high-voltage lines.
In order to effectively prevent the vehicle touching the high voltage line electrocution accident, the construction unit in addition to strengthening the driver's safety education and training, set up obvious high voltage line warning signs in the construction site, there is also a need to increase the technical level of protection, such as the installation of our company DX Wisdom Technology Real-time Distance Measuring Alarm for Near-Electricity Operation VehiclesDX-JDS100, when the vehicle is close to the high-voltage line to reach a certain distance, the device will send out an alarm in a timely manner, to remind the driver to take measures to avoid danger.
The real-time distance measuring alarm for near-electricity operation vehicles is also called high-voltage anti-electrocution alarm system, which is easy to install and disassemble as you go. The whole machine mainly includes a transmitting module installed on the side of the vehicle arm to detect the strong electric signal in real time, and a receiving end installed in the driver's cab to receive the returned signal in real time and carry out the early warning reminder. This equipment is mainly used for detecting outdoor overhead lines, the detection voltage and distance can be adjusted according to the site conditions; power supply mode, support for local power supply or battery power supply, can work continuously throughout the day, but also can expand the outdoor warning light linkage, in order to provide a wider range of early warning reminders.
