Sinopak 35kV Outdoor Air Cooled STATCOM for Electric Smelting Furnace
STATCOM
(Static Synchronous Compensator), also known as SVG (Static Var Generator)
The dust filter can not be cleaned regularly, the dust and water will be inhaled into power modules, and then, the mud will be attached to power boards.
Cooling air will change direction after they come through basement louvre, then go up to enter the container through dust filter at the bottom of STATCOM. After heat exchange, hot air will be forced to go out from container back. The gravity of sands will sink after changing direction from basement louvre. This solution is very suitable for sands area.
Hot air reflux design optimization：
1. The Moist air will enter power room during wet weather, cold weather, raining and snowing weather.
2. Hot air reflux design will avoid sands going into power room, but hot air also can be exhausted to atmosphere directly during dry and hot weather.

Our Advantage
1. Most effective high voltage active harmonic equipment in the industry
Sinopak TSVG successfully realize high voltage active harmonic filtering function from 3kV~35kV according to many years experiences. It can eliminate harmonics from 2nd to 13th completely. Compared with traditional SVC, SVG adopted active components. TSVG is not only used for dynamic reactive power compensation equipment, but also used for high voltage active harmonic filtering equipment directly.
Sinopak TSVG adopts cascade topology, with lower output harmonic content and very good filtering effect.
High Quality Power Units Design for moisture-proof and dust-proof.
Fully closed design of power unit control panel ensures operation stability in humid, windy and dusty environment, Control drive board on power unit adopts silicone material with good performance for potting. The silicone can stay resilient and stable within -55°C~+180°C, and has better thermal conductivity and insulativity, ensuring stable operation of SVG in salt-spray environment.
2. Control Cabinet Design Advantage
Fully closed design of control cabinet ensures use reliability in sand-dust or humid environment.
Fully closed design of control cabinet prevents external dust or soot from entering control cabinet. After being closed, it needs to receive heat dissipation; to ensure internal temperature within a reasonable range, upper and lower parts of control cabinet interior are respectively equipped with one fan for up-down and right-left circular flow of air in it so as to decrease the temperature.
Whole control system components are comprehensively screened, with low power consumption and high reliability, to improve whole system stability. Thermal simulation of FlOWTHREM software is used to control 67°C average internal temperature when external ambient temperature is 45°C so as to meet component temperature in service environment. It fundamentally solve dust prevention and pollution prevention problems.
3. Service Advantage
Power Module Tester
SVG mainly consists of many power modules, in order to help customers find module fault in time, Sinopak designed power Module tester, it is very easy and very fast to find the module faults.
By the way, Sinopak also install GPS module in SVG control room in order to help customer analyze SVG faults.
