Standardized Foundation Construction: Technical Guidelines For The Construction Of Constant Voltage Transformer Projects

In the planning of industrial power systems, the installation and foundation construction of constant voltage transformers are the cornerstone determining the quality of later operation. From design drawings to equipment delivery, every step verifies a mandatory requirement: the basic infrastructure of 3 phase constant voltage transformer must comply with relevant standards.

Following the Technical Framework of National Standards

The special characteristic of constant voltage transformers lies in their ferroresonant structure, making them highly sensitive to the installation environment and electrical parameters. Currently, the national standard GB/T 19212.13-2019, "Safety of Transformers, Reactors, Power Supply Units and Combinations Thereof - Part 13: constant voltage transformer for home and Particular Requirements and Tests for Power Supply Units," has defined the technical requirements for such equipment in detail. This standard not only replaces the earlier 2005 version but also clearly specifies the specific indicators for rated output, insulation performance, and electrical clearances. The foundation construction phase of the project must strictly adhere to these current specifications.

Compliance of Grounding System and Physical Space

The levelness of the embedded parts in the equipment foundation, the grounding resistance value, and the ventilation and heat dissipation channels are all covered by the specifications. Constant voltage transformers achieve voltage stabilization through magnetic saturation, generating vibration and heat during operation. The foundation construction must adhere to specifications, providing sufficient maintenance access and employing seismic-resistant fixing methods. The construction quality of the grounding system directly affects the equipment's ability to suppress common-mode interference; the construction team must lay the grounding grid according to the design drawings.

During the construction drawing review phase, the project team thoroughly understands these specification details to avoid cost waste from later modifications. This respect for specifications is a prerequisite for the long-term stable operation of industrial power systems.
