Product Detail

Description :

The circuit breakers are all equipped with pure spring operating mechanisms which makes structure simple and highly reliable. The mechanical endurance for the operating mechanism is over 10000 times, and it is convenient for maintenance and meets mechanism’s  requirements for oil free and air free. It uses self-energy arc extinguishing principle, and reduces operation power of the mechanism and enhance operational reliability of product. The flanges adopt dual-seal structural design, the outer seal ring is water-proof and inner seal ring is gas proof. Therefore, it can reduce the leakage of the product greatly and makes the product more suitable for outdoor operation.

Main function introduction:

  • High breaking current: Self-energy principle

  • Low breaking current: Puff type principle

  • Basic research ability

Q:What is the difference between SF6 live tank and dead tank?

A:In an SF6 live tank circuit breaker, the tank is at the line potential and energized during operation. It's usually lighter and more compact. In contrast, the tank of an SF6 dead tank circuit breaker is grounded, isolating the high - voltage parts. Dead tank types often have better insulation and are suitable for higher voltages, but they tend to be larger and heavier.

Q:What is a dead tank circuit breaker?

A:A dead tank circuit breaker is an electrical device for interrupting current in power systems. Its tank is grounded, isolating it from high - voltage parts. Filled with SF6 gas for insulation and arc - quenching, it's well - suited for high - voltage applications, offering good electrical performance and safety.

What is the difference between a dielectric and an insulator?
What is the difference between a dielectric and an insulator?
Dielectrics and insulators are distinguished primarily by their applications. One of the main differences is that a dielectric can store electrical energy by becoming polarized in an electric field, whereas an insulator resists the flow of electrons to prevent current conduction. Other key differences between them are outlined in the comparison chart below.Definition of DielectricA dielectric material is a type of insulator that contains few or no free electrons. When subjected to an electric fi

Fault Analysis and Treatment of Oil-Immersed Transformers
Fault Analysis and Treatment of Oil-Immersed Transformers
Oil Leakage at Welded JointsOil leakage at welded joints primarily stems from poor welding quality, such as incomplete or detached welds, and defects like pinholes and gas pores. Although oil-immersed transformers are initially coated with solder and paint during manufacturing, potentially masking these issues temporarily, the defects tend to surface during operation. Additionally, electromagnetic vibration can cause weld cracks, leading to oil leakage.To resolve such leaks, the first critical s

What losses occur during operation of the transformer? How to reduce losses?
What losses occur during operation of the transformer? How to reduce losses?
Transformers experience various types of losses during operation, primarily categorized into two main types: copper losses and iron losses.Copper LossesCopper losses, also known as I²R losses, are caused by the electrical resistance of the transformer windings—typically made of copper. As current flows through the windings, energy is dissipated in the form of heat. These losses are proportional to the square of the load current (I²R), meaning they increase significantly with high

I. Methods for Cable Testing and Inspection:Insulation Resistance Test: Use an insulation resistance tester to measure the insulation resistance value of the cable. A high insulation resistance value indicates good insulation, while a low value may suggest insulation problems requiring further investigation.Voltage Withstand Test: Apply a high-voltage test using a high-voltage tester to verify whether the cable can withstand high voltage under its rated operating conditions.
