Transformer Substation 10(6)kV

Description

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:

1. Tailored solutions (a wide choice of equipment to satisfy any need);
2. Installation within two weeks (the modules of transformer substations are delivered in high operational readiness to facilitate their installation on-site);
3. Robust design (using bolt joints and minimum welds, powder and aluminum-zinc coating, seismic strength up to 9);
4. Controlled assembly (to ensure all connection dimensions of power transformers and switchgears, check and adjust equipment at manufacturer’s site witnessed by client);
5. Comprehensive approach (equipment compatibility, in-house power transformers of own production, avoid risks and additional costs on fitting of various equipment);
6. Mounting Transformer Substation into E-House (any configuration upon customer’s request, possible outdoor location of Transformer Substation);
7. 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);
8. Reference to the existing facilities of customer (installation on any type of foundation);
9. Extended 5 Years warranty;
10. Uninterruptable power supply (automatic circuit breaker based on smart relay).

Main Features of Transformer Substation:

Quality

• 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.

Convenience

• 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.

Reliability

• Quality assurance at each operation of assembling to eliminate additional expanses;
• State-of-industry automated disconnectors and microprocessor protection units.

Safety

• 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.
