How to arrange the electrical assembly process of the control cabinet?

There is no process for air-open contactors for thermal protection.

What is the specific content of the installation and construction process of the complete set of power distribution cabinet and power switch cabinet, the following Zhongda Consulting will answer for you.

Chapter 1 Construction Preparation.

1.Equipment and material requirements: The equipment and materials are in line with the current technical standards issued by the state or the ministry, meet the design requirements, and have a factory certificate. The equipment should have a nameplate, and indicate the name of the manufacturer, accessories, and complete equipment.

Materials used for installation: The section steel should have no obvious reputation and corrosion, and there should be material proof. The secondary wiring wire shall have a certificate with the "Great Wall" mark. All fixed connection bolts must be galvanized products, flat and elastic pads.

2.Main machine installation tools: bench drills, hand drills, electric hammers, grinding wheels, electric welding machines, gas welding tools, etc.

Testing and inspection tools: megohmmeters, multimeters, levels, electric pens, steel tape measures, feeler gauges, line pendants, etc.

3.Working conditions: civil engineering construction is quiet and sensitive conditions: the construction of the indoor ground, wall and roof of civil engineering is completed, the doors, windows and glass are installed perfectly, and the doors are locked.

The construction drawings and technical data are complete. Technical, safety and fire protection measures are implemented.

The equipment and materials are complete and transported to the on-site warehouse.

Chapter 2 Operation Process.

Chapter 3 After the finished protective equipment is transported to the site, it should be covered with a tarpaulin in time and tied firmly to prevent the equipment from wind, sun or rain. During the handling of the equipment, it is not allowed to stand upside down to prevent damage to the paint and electrical components of the equipment. After the equipment is installed, it cannot be operated temporarily, and the doors and windows of the substation and distribution room should be closed and guarded.

Do not disassemble equipment parts and instruments without permission to prevent damage or loss.

The processing process of the electrical cabinet is as follows:

1. For the processing of the cabinet, if the advanced automatic flexible production line is adopted, and the drawings are input into the computer, the board required by the cabinet will be automatically cut and welded. If there is no fully automatic production line, a CNC cutting machine is used to cut piece by piece according to the drawing, and then weld.

2. Assembling the cabinet.

3. Spray or color the countertop.

4. Installation and cable of the devices in the cabinet.

5. Commissioning, factory acceptance.

Ningbo Yitong Electric is a manufacturer specializing in the production of automated control cabinets, low-voltage distribution cabinets, low-voltage distribution boxes, terminal combination boxes, power distribution boxes, electricity metering boxes, and construction site boxes.

After continuous development, pioneering, innovation and hard work, we have advanced equipment, perfect testing methods, professional design, and superb assembly technology team. In China, a certain market scale and sales network have been formed.

Generally, the customer provides the drawings, the manufacturer carries out the **, it is best to determine**, sign the contract, the manufacturer produces according to the contract, and finally the delivery and receipt.

Shanghai Huasheng Electric, a more professional electrical equipment manufacturer in Shanghai, provides equipment and electrical engineering installation.

Design drawings according to the requirements and issue a material table. Purchase components and other auxiliary materials according to the bill of materials, including cables, wire caps, trunking, etc., and of course the housing must also be determined. According to the reasonable design layout of the shell space, and then the components are fixed on the cabinet installation backplate according to the layout, and the control cabinet panel is also opened according to the size of the indicator light and button, and the indicator light and button are installed.

All that's left is to connect, first the main line, then the control line. After powering on, try to see if it can start and stop normally, and whether there is smoke.

Building electrical construction and installation technology-92Substation and distribution equipment installation process.

The installation of complete sets of distribution cabinets, control cabinets (screens, tables) and power and lighting distribution boxes (panels) should be carried out according to the following procedures:

1. Only after the buried basic steel and cabinets, screens, cable trenches and other related buildings under the platform are inspected and qualified, only then can the cabinets, screens and platforms be installed;

2. The foundation acceptance of the indoor and outdoor floor-to-ceiling power distribution box is qualified, and the wire conduit and cable conduit that are incorporated into the foundation are inspected before the box can be installed;

3. The embedded parts (metal embedded parts and bolts) of the power and lighting distribution box (plate) installed on the wall shall be reserved and embedded before plastering; The concealed power, the reserved hole and power of the lighting distribution box, the wiring box and the wire conduit of the lighting wiring, etc., can be installed only after inspection and confirmation that they are in place;
