JLSW3-10 Outdoor Oil-Immersed Combined Transformer, metering tank

Overview of JLSW3-10 Outdoor Oil-Immersed Combined Transformer, metering tank

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 JLSW3-10 Outdoor Oil-Immersed Combined Transformer, metering tank

• 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.

Specifications of JLSW3-10 Outdoor Oil-Immersed Combined Transformer, metering tank

This unit combines a transformer and metering tank in one outdoor oil-filled design. It handles 10kV systems. The metering tank sits separately. This improves safety and simplifies checking electricity use.

The tank holds transformer oil. Total oil volume is 25kg minimum. This ensures good cooling and insulation for the transformer parts inside. The tank body uses thick steel plate. The steel is strong. It resists weather and corrosion well. The whole structure is welded tight. This prevents oil leaks. It keeps the internal parts safe.

The tank has a specific shape. Its design follows standard electrical requirements. The overall size is compact. This saves space at the installation site. The tank includes necessary fittings. These allow for easy filling and checking of the oil level. Oil level is visible clearly. This helps with regular maintenance checks.

Pressure testing is done rigorously. The tank withstands high internal pressure. This proves its strength and leak-proof seal. The unit meets strict national standards. Key standards include GB/T 16927.1 for insulation and GB 1094.1 for transformers. These certifications guarantee reliable operation.

Installation is straightforward. The unit mounts securely on poles or platforms. It connects directly to the 10kV power lines. The separate metering compartment simplifies wiring for electricity meters. Technicians can access meters safely. They do not need to work near high-voltage transformer parts.

The oil provides essential insulation. It also cools the transformer core and windings. The oil quality is high. It maintains stable performance over time. Regular oil checks are part of maintenance. This ensures long service life. The design handles typical outdoor conditions. It works fine in rain, sun, and varying temperatures. The robust construction offers dependable service for power distribution networks.

Applications of JLSW3-10 Outdoor Oil-Immersed Combined Transformer, metering tank

The JLSW3-10 Outdoor Oil-Immersed Combined Transformer Metering Tank is a key piece of equipment for managing electricity distribution outside. It puts several vital functions into one strong unit. This unit handles high voltage switching, electricity measurement, and voltage transformation. Its main job is stepping down 10kV high voltage to safer, usable 400V low voltage levels. It also accurately measures how much electricity flows through the system.

You see this combined unit often in outdoor electrical substations. It works well feeding power to factories, workshops, and large commercial buildings needing their own transformers. It’s also common in smaller town substations and rural power supply networks. Places needing reliable power distribution find it very useful. Its compact design saves significant space compared to separate devices.

The transformer core sits inside a tough steel tank filled with special insulating oil. This oil cools the transformer and prevents electrical breakdown. The tank is sealed tight to keep the oil clean and dry. This design withstands harsh weather conditions year-round. The integrated metering tank houses the electricity meters. It protects them from the environment and potential tampering.

This combination offers big advantages. It simplifies installation. You only need to set up one unit instead of several separate pieces. This cuts down installation time and labor costs. It also reduces the land area needed for the equipment. The design improves safety. The high-voltage parts are securely enclosed and immersed in oil. Maintenance is easier too. Technicians deal with just one integrated system. The metering tank provides clear access for reading consumption data. It helps utilities manage power supply efficiently.

5 FAQs of JLSW3-10 Outdoor Oil-Immersed Combined Transformer, metering tank

JLSW3-10 Outdoor Oil-Immersed Combined Transformer, Metering Tank: Top 5 Questions

1. What exactly is this JLSW3-10 unit?
This unit combines two things. It is a transformer. It steps down high voltage electricity to safer, usable levels for homes or businesses. It also has a built-in metering tank. This tank measures exactly how much electricity passes through it. You see this unit mounted on poles outdoors. It connects power lines to buildings.

2. Why is the transformer filled with oil?
The oil does two important jobs. It cools the transformer. Transformers get hot working. The oil also insulates the internal parts. This insulation stops dangerous electrical shorts. The oil helps the transformer last long.

3. What keeps the metering tank safe?
The metering tank sits inside a strong steel compartment. This compartment is locked. It protects the meter from weather. It protects the meter from tampering. Only authorized people can open it. This ensures accurate billing.

4. Does this unit need much maintenance?
It needs regular checks. Workers look at the oil level. They check for leaks. They clean the outside surfaces sometimes. They inspect the connections. They test the meter accuracy. Proper maintenance keeps it reliable.

5. How do you install this transformer?
Installation requires trained utility workers. They mount it securely on a sturdy pole or platform. They connect the high-voltage power lines correctly.
