Transformer Substation includes several HV cabinets and LV switchgears with the built-in devices, instruments, relays, alarm and controls, as well as power transformers. Transformer Substation can be built in the existing facility.
Special Options of Transformer Substation:
- Tailored solutions (a wide choice of equipment to satisfy any need);
- Installation within two weeks (the modules of transformer substations are delivered in high operational readiness to facilitate their installation on-site);
- Robust design (using bolt joints and minimum welds, powder and aluminum-zinc coating, seismic strength up to 9);
- Controlled assembly (to ensure all connection dimensions of power transformers and switchgears, check and adjust equipment at manufacturer’s site witnessed by client);
- Comprehensive approach (equipment compatibility, in-house power transformers of own production, avoid risks and additional costs on fitting of various equipment);
- Mounting Transformer Substation into E-House (any configuration upon customer’s request, possible outdoor location of Transformer Substation);
- Optimal Configuration, free from any excessive elements (own energy efficient dry-type cast resin transformers ensure saving on possible loss and make it totally unnecessary to keep and oil facility);
- Reference to the existing facilities of customer (installation on any type of foundation);
- Extended 5 Years warranty;
- Uninterruptable power supply (automatic circuit breaker based on smart relay).
Main Features of Transformer Substation:
- State-of-industry high-quality components and materials (secondary circuits devices by Schneider Electric, busbar systems by ABB, switching circuit busbars by Valjaonica Bakra Sevojno, Serbia), to ensure quality and reliability of Transformer Substation;
- Frame and all internal bearing elements made of high-quality thin steel sheets with anti-corrosion aluminum-zinc coating that securely preserve the equipment within the whole life cycle;
- Doors and external panels are made of high-quality steel sheets with powder polyester exterior-type coating. The coating is applied by electrostatic spraying to ensure reliable even coating maintaining their protective properties within the whole service life.
- Modular design of Transformer Substation to make equipment of various configurations;
- Easy mounting of additional outgoing sections (subject to availability of space), or replacing switches on other rated current, with minimal costs, material and time;
- Equip automatic circuit breaker with any microprocessor protection units at any level of complexity, including integration into SCADA;
- Standard configuration of Transformer Substation contains Zelio Logic Smart Relay to allow customer adjust the logic of automatic circuit breaker independently or with support of our experts;
- Automatic circuit breaker can be made upon customer’s request.
- Quality assurance at each operation of assembling to eliminate additional expanses;
- State-of-industry automated disconnectors and microprocessor protection units.
- Design solutions ensure the requested internal partitioning of all functional elements. The partitioning meets the requirements of GOST Р 51321.1-2000, form 3а or 3b (4b – optional, upon customer’s request);
- Such separation ensure safe maintenance and ability to locate possible failures within an affected compartment;
- Switching control and monitoring devices are mounted on the front panels of cabinets. Switches are operated even with the door closed;
- Drawout switches allow their maintenance with the busbars (of the transformer substation) energized.
Advantages of Transformer Substation:
- Pre-fabricated elements;
- Minimum welds; galvanized steel sheets;
- Flexible design and fast replacement;
- Optional configuration: one-type modules can be easily combined into multi-module substations;
- Integrated delivery;
- Max level of operational readiness;
- Min dimensions;
- Applicable for outdoor use, if mounted into E-House;
- Compatible with Dry-Type Cast Resin Transformers, which relieves from the need to establish and maintain an oil facility;
- Meet the shipment dimensions;
- Fit for any type of foundation;
- Seismic Strength up to 9 (MSK-64).
