Factory Direct Oil-immersed Transformer Tap Changer Switch WST II 125/10-8X7

Overview of Factory Direct Oil-immersed Transformer Tap Changer Switch WST II 125/10-8X7

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of Factory Direct Oil-immersed Transformer Tap Changer Switch WST II 125/10-8X7

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

Applications of Factory Direct Oil-immersed Transformer Tap Changer Switch WST II 125/10-8X7

This WST II 125/10-8X7 oil-immersed transformer tap changer switch is built for demanding factory settings. It handles heavy power loads reliably. Its main job is adjusting the transformer’s voltage ratio. This is vital for keeping voltage stable. Voltage fluctuations happen often in industrial environments. Machines starting or stopping causes them. Production lines changing speed causes them too. The tap changer switch makes corrections automatically. It prevents voltage dips or surges. This protects sensitive equipment. Motors and control systems need steady voltage. Process stability depends on it.

Power plants use this switch. It helps maintain consistent output voltage. Grid stability relies on this. Large factories depend on it too. Facilities like steel mills or chemical plants have huge power demands. Their transformers need robust tap changers. The WST II 125/10-8X7 fits this need. It works directly immersed in transformer oil. The oil cools the switch effectively. The oil also insulates the contacts. This design ensures long service life. It handles high currents safely.

Renewable energy sites benefit greatly. Wind farms and solar installations see variable power generation. Wind speeds change constantly. Sunlight intensity shifts throughout the day. This causes fluctuating voltage levels. The tap changer switch compensates for these changes. It keeps the voltage feeding into the grid stable. This is critical for grid code compliance. Power quality must meet standards.

Water treatment plants need reliable power. Pumping stations use large motors. Voltage stability is essential for motor performance. The tap changer ensures smooth operation. Mining operations face similar challenges. Heavy machinery creates significant load variations. Consistent voltage prevents downtime. It protects expensive extraction equipment.

5 FAQs of Factory Direct Oil-immersed Transformer Tap Changer Switch WST II 125/10-8X7

Here are 5 FAQs for the Factory Direct Oil-immersed Transformer Tap Changer Switch WST II 125/10-8X7:

What is the WST II 125/10-8X7 tap changer switch?
This switch adjusts the transformer voltage. It changes the winding connection points. It is designed for oil-filled transformers. The switch operates submerged in insulating oil. The oil cools the switch. The oil also insulates the electrical parts.

How does this tap changer work?
The switch has a selector mechanism. This mechanism moves between fixed contacts. The contacts link to different transformer winding taps. Moving the selector changes the effective turns ratio. Changing the turns ratio adjusts the output voltage. The switch offers 8 positions. The switch has 7 steps for fine voltage adjustment. It handles 125 amps maximum current. It is rated for 10kV systems.

How is the switch installed?
Install the switch directly on the transformer tank. Mount it securely. Connect the leads to the correct transformer winding taps. Make the connections carefully. Ensure the switch is fully submerged in clean transformer oil. The oil quality is critical. Good oil prevents electrical breakdown. Follow the manufacturer’s wiring diagram exactly. Improper wiring causes failure.

What safety features does it have?
The switch operates inside the sealed transformer tank. The oil environment provides inherent safety. The oil quenches any switching arcs. The robust mechanical design prevents accidental movement. The switch housing is durable. It withstands the oil pressure. It also withstands normal transformer vibrations. Only qualified personnel should service the transformer. The transformer must be de-energized first. Opening a live transformer is extremely dangerous.

What maintenance is required?
Check the transformer oil condition regularly. Test the oil’s dielectric strength. Test the oil for moisture. Test the oil for acidity. Replace degraded oil promptly. Bad oil damages the switch contacts. Inspect the switch contacts during major transformer maintenance. Look for signs of wear. Look for signs of arcing. Look for signs of overheating. Clean the contacts if necessary. Ensure the selector mechanism moves smoothly. Lubricate the mechanism as specified by the factory.
