The construction site is arranged by electricity, the construction site is relatively large, and how

Summary. The horizontal distance between the switch box and the fixed electrical equipment controlled by it should not exceed 3m.

The main distribution box should be located close to the power supply, and the distribution box should be installed in the area where the electrical equipment or load is relatively concentrated, and the distance between the distribution box and the switch box shall not exceed 30m, and the horizontal distance between the switch box and the fixed electrical equipment controlled by it shall not exceed 3m.

The installation of the distribution box and switch box should be upright, firm and mobile, and the mobile box should be located on a solid support. The vertical distance between the lower skin of the fixed distribution box and the switch box and the ground should not be greater than or less than. The mobile distribution box and switch box are made of iron plate or high-quality insulating materials.

The thickness of the iron plate should be greater than.

The construction site is relatively large, how to arrange the electricity.

Hello, I have seen your question and am sorting out the answer, please wait for a while The horizontal distance between the switch box and the fixed electrical equipment controlled by it should not exceed 3m, etc. The total distribution box should be located close to the power supply, and the distribution box should be installed in the area where the electrical equipment is located or the load is relatively concentrated, and the distance between the distribution box and the switch box shall not exceed 30m, and the distance between the switch box and the level of the power equipment controlled by the solid spring orange shall not exceed 3m. The installation of the distribution box and switch box should be upright, firm and mobile, and the mobile box should be located on a solid support.

The vertical distance between the lower skin of the fixed distribution box and the switch box and the ground should not be greater than or less than. The mobile distribution box and switch box are made of iron plate or high-quality insulating materials. The thickness of the iron plate should be greater than.

1. Reasonable arrangement: the purpose of the on-site investigation is to make a reasonable layout for electricity, to first understand the local power situation, whether it can meet the needs of construction, whether there are frequent power outages, power outage time, whether the voltage is stable, such as the construction unit has been connected to the power supply, check whether the transformer capacity meets the requirements, whether the location of the power supply and the line hinders the construction, and the impact of the terrain of the construction site on the layout of electricity.

2. Electricity planning: have a comprehensive understanding of the situation of the entire construction site, grasp a large number of design data, conform to the trend of the construction site of the electricity plane planning, layout, determine the power supply line, substation, distribution room, general distribution box, distribution box and other locations and line direction, if the self-provided generator set, to determine the location of the power generation room and the direction of the transmission line.

3. Equipment layout: the location of the power supply line, transformer, distribution room, and generator room should be selected in a place that does not hinder construction, does not accumulate water, ventilates, has no dust, no vibration, and has higher terrain, and the main distribution room should be located near the power supply, and the distribution box should be installed in the place where the electrical equipment or load is concentrated.

4. Line mode: For the construction site without transformer, a leading line can be arranged along the perimeter of the site, or along the place where electricity is concentrated, and the power consumption is led out with a branch line. The construction site with transformers can provide power supply for multiple trunk lines, which is generally suitable for large and medium-sized projects and cluster projects, such as the construction site is particularly large, and can be subdivided into regional power supply, and the layout of the line is radial, trunk, chain, etc., which is selected according to the actual situation.

The erection of the main line of power supply should be standardized and firm. When the line crosses highways, railways, and traffic arteries, it should be erected in accordance with the requirements of the code to ensure safety.

How to arrange the construction site line.

Temporary electricity scheme on the construction site:

1. The construction electricity is implemented by itself, and after the on-site investigation of our company, the construction electricity of our unit is introduced into the distribution box in the high-voltage distribution cabinet that the owner has introduced into the site. In accordance with the "Technical Specifications for Temporary Electricity Consumption on the Construction Site", the three-phase five-wire system is adopted for the power lines, and the electrical equipment at the construction site implements the principle of "one machine, one box, one gate, one lock, and one leakage protection".

2. Reasonable configuration, setting, replacement and maintenance of various protectors, feasible protection for overload and short circuit faults of circuits and equipment.

3. All distribution boxes must be fully locked, there are warning signs on the door, the box is cleaned, the wiring and switches should be arranged neatly, the fuse and wire should be matched, it is forbidden to replace the fuse with other metals, and the machine must be protected from zero; When replacing machinery and equipment, the distribution box should be supervised by a special person, and the equipment must be operated and managed.

4. Establish the mechanical and electrical safety management regulations and various inspection systems of the project, and there should be mechanical and electrical workers on duty day and night during the construction period to deal with mechanical and electrical accidents, and non-full-time personnel shall not touch the electrical equipment.

Organizational design is:ProgrammaticYes, the scheme isGuidance on how to do itTarget.

If there are 5 or more temporary electrical equipment on the construction site or the total capacity of the equipment is 50kw or above, it shallPreparation of electricity consumption organization design

If the temporary electrical equipment on the construction site is less than 5 and the total capacity of the equipment is less than 50kw, it should be formulatedSafe use of electricity and electrical fire prevention measures.
