Box type substation installation: 7 suggestions to prevent problems with box type substations!

In some large construction sites, temporary electricity usually requires the installation of box type substations to meet the electricity load. However, the temporary power supply site has a simple environment, which often leads to various quality problems during the use of the transformer due to negligence during the installation phase. Next, the editor will summarize several suggestions for preventing problems with box transformers:

1. Strictly control the quality of box type substations, cables and wires, starting from the source, and strengthen the design depth and review efforts. Regarding equipment technology issues, specific allowable values should be specified in the ordering agreement to reduce disputes over inconsistent standards during acceptance.

2. The manufacturer of the designed transformer should attach great importance to the isolation of the terminal block. During product design, it is necessary to implement isolation of AC/DC terminals, positive and negative power terminals, and different control circuits to avoid such faults from the source.

3. Strengthen process control during the installation of transformer boxes, enhance the quality awareness of installation personnel, familiarize them with electrical specifications, and strictly follow the specifications during construction.

4. Improve cable laying, organization, and secondary line work, promote competition management among colleagues, strengthen the responsibility system, and fully mobilize the enthusiasm and innovation of construction personnel. Strict process control is required for cable signage, binding, and cable sealing.

5. Strengthen debugging during the installation process to ensure the normal use of the equipment.

6. Strengthen on-site supervision, ensure installation quality through inspections, spot checks, etc., constrain installation companies' construction, and standardize construction quality.

7. Strengthen the internal acceptance system of the installation company, timely discover and eliminate defects, and eliminate engineering quality problems before equipment is put into operation.

Summary: Temporary power installation should also choose appropriate protective measures based on the complexity of the on-site situation to avoid dust, corrosive substances, water vapor, etc. from entering the interior of the box type substation and causing unnecessary losses. If there is a moisture problem inside the transformer box, an anti condensation device can be installed inside the box for dehumidification.
