35kV Fully Insulated Gas-Filled Circuit Breaker Cabinet
XGN40-.5/V
Customized according to drawings, suitable for 35kV power lines, spring energy storage operating mechanism (integrated with circuit breaker), 630A vacuum switch for transformer/line protection.
The gas-filled cabinet is a complete set of power distribution equipment that seals high-voltage switchgear, busbars, transformers and other high-voltage electrical components in a metal shell filled with insulating gas (such as sulfur hexafluoride SF₆). The following is its description and application introduction:
Structure and principle
- Structure: It is mainly composed of cabinet, gas-filled compartment, operating mechanism, control and protection device and other parts. The cabinet is made of metal and has good mechanical strength and protection performance. The gas-filled compartment is the core part, which is filled with insulating gas to provide a stable insulation environment for high-voltage electrical components.
- Principle: The high insulation strength and good arc extinguishing performance of the insulating gas enable the equipment to reliably distribute and control electric energy. When the switchgear is opened and closed, the insulating gas can quickly extinguish the arc, prevent the arc from reigniting, and ensure the safe operation of the equipment.
Features
- Good insulation performance: The insulating gas has high insulation strength, which can effectively avoid phase-to-phase and ground short circuits and reduce the size of the equipment.
- Strong sealing: It adopts a sealed structure, which is not affected by external environmental factors such as humidity and dust, and has high operating reliability.
- Strong arc extinguishing ability: can quickly extinguish arcs, reduce the wear of switch contacts, and extend the service life of equipment.
- Low maintenance: internal components are sealed in the air-filled compartment, no frequent maintenance is required, and maintenance costs are reduced.
Application
- Industrial field: widely used in power supply and distribution systems in factories, mines, metallurgy and other places, providing stable power supply for various industrial equipment. It can adapt to harsh industrial environments and ensure reliable operation of equipment under conditions such as high dust and high humidity.
- Commercial field: in the distribution rooms of commercial buildings such as shopping malls, office buildings, and hotels, it can realize the reasonable distribution and control of electric energy, meet the large power demand of commercial facilities, and ensure the safety and reliability of power supply.
- Power system: as an important distribution equipment in power systems such as substations and switchgear, it is used for the transmission and distribution of electricity. It can be used in conjunction with other power equipment to achieve flexible control and protection of the power system.
- Residential areas: Provide reliable power distribution support for the power supply system of residential areas, convert high-voltage electricity into low-voltage electricity suitable for residents, and ensure residents' daily electricity consumption.
