1. Product overview
The ring network cabinet body is riveted and formed by 2mm thick aluminum zinc plate (or cold-rolled steel plate spraying), and there are two pressure relief holes behind the cabinet to release the gas pressure generated by arc accidents inside the busbar, load switch and cable chamber; This product has the characteristics of small size, light weight, beautiful appearance, simple operation, long life, less maintenance and high protection level.
Inside the cabinet is a three-phase common box type sulfur hexasulfide load switch, which is modeled FLN36-12 or FLRN36-12D.
2. Product use
XGN15-12 unit AC metal ring network switchgear is suitable for AC 50HZ, 12KV power system, as the reception and distribution of electric energy.
3. Environmental conditions of product use
(1) Ambient temperature: the upper limit is +40°, the lower limit is -25°.
(2) The altitude does not exceed 1000m.
(3) The daily average of relative humidity is not more than 95%, and the monthly average is not more than 90%.
(4) There is no risk of fire and explosion, no severe vibration and chemical corrosion and other serious pollution places.
XGN15-12 metal-enclosed box ring network high-voltage switchgear is suitable for three-phase AC power distribution systems with a rated voltage of 12KV and a rated frequency of 50Hz in industrial and mining enterprises, high-rise buildings, residential areas, hospitals, schools, parks, etc., as a purpose for receiving and distributing electric energy. They can be used for ring and terminal power supply, as well as for installation into box-type substations.
The ring network cabinet body is riveted and formed by 2mm thick aluminum zinc plate (or cold-rolled plate spraying), and there are two pressure relief holes behind the cabinet, one for the cable room and the other for the load switch/busbar room. The substructure ensures maximum personal safety and reliability of operating equipment. The busbar room is located on top of the cabinet and connects the adjacent switch cabinets. The load switch is a self-contained unit filled with SF6 gas. Approximately 75% of the space is used for cable connections, fuses, grounding switches and CT and PT installations.
Structural features:
1. Appearance: the shell is stamped and formed by aluminum zinc plate; Beautiful appearance, strong corrosion resistance, compact and reasonable structure, small size, very convenient combination. There are four mutually insulated compartments within the frame, with a pressure relief at the back.
2. Easy installation: can be arbitrarily combined, expanded, flattened, fast and simple according to various design requirements, installation is very simple and convenient, small land occupation, no special requirements for installation size.
3. Maintenance-free: the switch has good sealing, SF6 insulating gas pressure meets the relevant provisions of IEC60298 standard, safe and reliable operation, maintenance-free.
Design Advantages:
1. Pressure release: The busbar room and cable room are provided with pressure relief ports to ensure pressure discharge under extreme conditions and ensure personal safety.
Three-station/double-station: The switch is naturally interlocked and can only be used in one of three positions: "closed", "grounded" or "interlocked".
2. Interlock position: the switch is interlocked with the operating mechanism, which prevents the occurrence of human misoperation. The operating mechanism is interlocked with the high-voltage cable room to prevent the switch from opening the installation cabinet door when it is not grounded to ensure the safety of personnel.
3. Panel display: the panel simulates a primary loop, the indication is clear and clear, and the live display flashes to indicate the live part.
4. Independent interval: Four rooms are set up separately to prevent the expansion and spread of sudden accidents.
