Problems faced by temporary power management in construction sites

Management neglect, chaos：Layers of subcontracting, uneven power management level, chaotic scene; Due to the neglect of management, the power supply of the construction site is not standardized; Cross operation is very random, the line is confused, resulting in increased risk of electric shock.

No equipotential bonding：The construction site is a place without equipotential connection, and the risk of death by electric shock is greater under the same fault conditions.

The insulation level decreases in harsh environments：The construction site is a place with bad environment, wind, rain, sun and other bad weather conditions make the electrical insulation level decrease; The operation of many transport vehicles and construction machinery causes mechanical damage to electrical equipment and wire Louis crushed by impact.

Frequent site changes cause mechanical damage：The distribution box, socket, wire and cable and other equipment lines for construction need to be replaced frequently, and the entire construction site is a temporary electrical device; Frequent moving and transportation is very easy to cause mechanical damage to equipment and lines, leaving hidden dangers of accidents.

Power inspection and monitoring rely on manual, limited means：Line damage ignition, overheating without timely alarm and monitoring; Failure to warn of aging of facilities, unlimited power and current; Single leakage protection switch, failure without detection; There is no technical protection for closing and closing, and there is no hierarchical control.

The moisture resistance of workers' skin decreased：The construction personnel working in the construction site are often splashed by water and rain during the operation, which makes the skin wet and the human impedance decrease; Hand-held and mobile electric construction tools that are hard to get rid of.

Temporary power management solution for Manton site

（一）Overview of the Manton scheme

The construction site electricity can be implemented by relying on scientific and technical specifications, and the supervision and inspection previously carried out by manual, can be directly supervised online through Manton's intelligent air switch and the cloud platform supported behind.

High power management efficiency, no dead corners, fine, platform and APP can directly see each device's various power data, leakage, ignition, overload and so on.

It can flexibly adjust the power consumption plan at any time according to the needs, and it can be easily retracted and released, which changes the previously rigid power consumption management mode.

For the Group construction Group, the headquarters can directly monitor all construction sites, and the top level can directly obtain first-hand electricity information.

（三）Manton program highlights

Automatic check, power planning can be adjusted at any time：Daily, weekly, monthly, start, resume the inspection of automatic timing, seconds to complete, form a standard report; The power consumption plan can be adjusted at any time, the management is simple and effective, and the work of management and electricians is simplified, reducing people and increasing efficiency.

The leakage protection threshold can be adjusted automatically：The threshold of leakage protection can be configured according to the weather and humidity changes, for example, the manual operation of the motor on rainy days, the leakage threshold is configured to 15mA or less

Exclusive permission to switch on and off：During the work or maintenance process, the operating electrician has the sole authority, and other people can not switch on and off manually or remotely; The distribution box and switch box do not need to be locked for an hour, and the Manton scheme can set the on-duty electrician as the only management authority to open the switch, and others can not use the electrical equipment manually or remotely.

Automatic judgment of closing conditions：The switch at all levels in the process of opening and closing, forcing the lower switch does not open, the upper switch can not open, the upper switch does not close, the lower switch can not close.

Alarms such as ignition, overload, and overcurrent：Ignition, overload, overtemperature, overcurrent and other alarms and automatic power off; You can set the power and current thresholds of a switch, generate an overload alarm and power off, prevent multiple electrical devices from being connected, multiple electrical devices from being connected, or use overpower devices.
