Sinopak 35kV Outdoor Water Cooled STATCOM for Mining Hoist
(Static Synchronous Compensator), also known as SVG (Static Var Generator)
SVG is a chain-type static synchronous compensator (STATCOM/DSTATCOM, also knows as SVG) —active dynamic reactive and harmonic compensation device at different compensation ranges.
Water cooled SVG adopts high degree of protection(IP55), Power valve tower are placed in a sealed space, heat is took away through water cooling system, there is no interaction with outer environment.
More higher reliability
The working condition of power module in water cooled SVG is more better compared with air cooled SVG. Power module in water cooled SVG has good heat dissipation conditions, working shell temperature and junction temperature more less compared with air cooled SVG, which increased IGBT reliability and life.
Normal Environment
Under normal circumstances, due to water-cooled SVG needs a set of water cooling system, its initial investment cost will be higher than the air-cooled SVG.
Badly Environment
In the harsh environment, the air-cooled SVG needs dehumidification or air-conditioning scheme to compensate for its defects, which not only increase the initial investment but also increase the area of installation, and the effect is not as good as water-cooled SVG.
Maintenance cost
Air cooled needs regular cleaning and replacement of dust filter, its maintenance costs will be higher than the water-cooled SVG in future.

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.
