Product Detail

Description

The ring main unit switchgear uses SF6 gas as arc extinguishing and insulating medium.

The switchgear is a fully sealed and fully insulated structure. Busbars, switches and live parts are completely enclosed in stainless steel housings.

The protection level reaches IP67.

Switchgear has a complete "five protection" interlocking device to prevent personnel and equipment malfunctions that may be caused by human misoperation.

All switchgears have reliable safety relief channels to ensure operator safety even in extreme situations.

The switchgear is divided into two types: fixed unit combination and expandable unit combination.

The switchgear usually enters and exits the cable from the front, and can also realize the side exit or side expansion according to different installation positions.

The size of the cabinet is easy to install, and it can be suitable for places with small space and poor environmental conditions.Electric, remote control and monitoring devices can be configured according to the different needs of users.

Feature

24kV-class high-efficiency insulation: Utilizes SF₆ gas as the insulating medium, with insulation strength adapted to the 24kV voltage level and excellent arc-extinguishing performance. It can stably block current leakage in high-voltage environments, significantly reducing the risks of short circuits and flashovers, and ensuring the reliable operation of medium-voltage power grids.
Compact space adaptation: Boasts a small and compact structural design with a small footprint, making it particularly suitable for space-constrained scenarios such as urban distribution stations and industrial parks. It simplifies installation layouts while improving site utilization.
Multiple safety guarantees: Equipped with complete mechanical and electrical interlocking devices to prevent misoperations and incorrect switching; features a built-in SF₆ gas leakage monitoring system that provides real-time warnings of leakage risks. It complies with international medium-voltage equipment safety standards to ensure safety during operation and maintenance.
Low maintenance and long service life: The fully sealed gas chamber design effectively isolates dust, moisture, and corrosive substances, reducing erosion of internal components by the external environment. It enables long-term maintenance-free operation with a service life of over 20 years, significantly lowering the whole-life-cycle cost.
Flexible power distribution compatibility: Supports multiple wiring methods such as ring network and radial types, and can be quickly connected with 24kV-class transformers, cables, and other equipment. It adapts to the topological requirements of different medium-voltage distribution networks, meeting diverse power supply scenarios including urban power grids and large industrial plants.
Balance of environmental protection and economy: SF₆ gas is recyclable and reusable, reducing resource waste; the equipment has low operating energy consumption, and long-term usage costs are controllable, balancing environmental protection requirements and project economic benefits.

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

Cable Fault Detection, Testing, Location and Repair

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. Under normal circums

Transformer Detection, Testing, Maintenance and Servicing

Transformer testing, inspection, and maintenance are essential tasks to ensure normal operation and extend the service life of transformers. Below are some recommended steps:Visual Inspection: Regularly inspect the transformer's exterior, including the enclosure, cooling system, and oil tank. Ensure the enclosure is intact, free from corrosion, damage, or leakage.Insulation Resistance Testing: Use an insulation resistance tester to check the transformer's insulation system. Verify that the insul
