European-type Prefabricated Substation

European-type Prefabricated Substation is an integrated power distribution solution that combines high voltage switchgear, distribution transformer, low voltage switchgear, protection, control, and monitoring systems inside a factory-assembled enclosure.

The Prefabricated Substation typically adopts a three-compartment structure consisting of a high voltage room, transformer room, and low voltage room. This design provides independent functional separation for medium voltage switching, voltage transformation, and low voltage distribution, improving safety, maintenance convenience, and system integration.

As a complete Substation solution, it can be configured with oil immersed transformers, dry type transformers, or amorphous alloy transformers, together with RMU, vacuum circuit breakers, protection relays, power compensation, PLC, and SCADA communication interfaces according to project requirements.

(2) Construction quality for works related to box‑type transformer installation shall comply with current national codes for construction and acceptance of building works. (3) Positions of embedded parts and pre‑buried cable conduits shall satisfy design requirements, and all embedded parts shall be securely fixed. 2. Construction Preparation 2.1 Transformer Foundation Inspection (1) Inspect the construction quality of the transformer foundation and fill in the inspection record sheet. The record shall be signed and confirmed by all relevant parties. Any defects found shall be reported and rectified promptly. (2) Carefully verify the horizontal and longitudinal axis dimensions of the transformer foundation as well as the positions of pre‑buried conduits, and cross‑check against drawing dimensions. Proceed with subsequent work only after all dimensions are confirmed correct. 2.2 Transformer Unpacking Inspection (1) Upon arrival, the transformer shall be unpacked and inspected jointly by representatives of the owner, supervisor and manufacturer. (2) Measure and record the reading of the shock recorder before unloading; the impact value shall be less than 3G. (3) Inspect the transformer exterior for damage and confirm complete paint finish, and keep relevant records. (4) Check internal components of the transformer for displacement, contamination and other abnormalities. 3. Transformer Positioning & Installation (1) Mount the channel‑steel foundation onto embedded parts. Perform levelling and alignment. Weld the channel‑steel foundation firmly to embedded parts. Remove welding slag from welds and apply anti‑corrosive paint. (2) After hoisting the fan unit, hoist the transformer directly onto the foundation, then use jacks for levelling and alignment. (3) Connect the transformer to the foundation following the fixing method (bolted connection or welding) specified by the manufacturer. (4) In case of split delivery, install the enclosure after the transformer is positioned and oriented. (5) Affix nameplates and clean the interior of the transformer cabinet. (6) Implement finished‑product protection prior to commencing subsequent procedures.

    Do Dry‑Type Transformers Need to Be De‑energized?

    Dry‑type transformers are widely applied for local lighting, high‑rise buildings, airports, wharves, CNC machinery and other facilities. Simply put, a dry‑type transformer is a transformer whose core and windings are not immersed in insulating oil. Under what conditions shall a dry‑type transformer be immediately de‑energized? Fire occurs on the dry‑type transformer; the unit must be shut down immediately. Severe damage or discharge phenomena are observed on the transformer bushing. Stop operation immediately and arrange inspection by qualified professionals. Heavy smoke is emitted from the transformer. Abnormal, loud internal noise accompanied by explosion‑like sounds inside the transformer. Immediate shutdown is mandatory to prevent hazardous accidents. Abnormally high and continuously rising temperature under normal load and cooling conditions. When any of the above‑mentioned symptoms appear, the dry‑type transformer must be de‑energized right away. Continuing operation under such faults may cause personal injury as well as permanent damage to the transformer. These issues shall be addressed promptly. Exercise great caution when encountering any of the above‑mentioned conditions to avoid hazards. Yizheng Hongxin Transformer Co., Ltd. specializes in transformers, including dry‑type transformers, power transformers and oil‑immersed transformers. As a transformer manufacturer based in Jiangsu Province, our plant produces dry‑type transformers, power transformers and oil‑immersed transformers.
