XGN15 Metal-Enclosed Switchgear

HXGN15-12 series products are composed of standard functional units processed by the factory, using advanced FLN36 load switches and SF6 gas as arc extinguishing insulation medium with superior performance. The cabinet has a small size, reasonable and compact size, convenient installation, simple operation, and safe and stable operation, and is widely recognized in 10 kV power supply and distribution systems

Product model and meaning

Easy installation

1. The cabinet has a small size and light weight, making it easier for users to transport and install. The device can be connected according to user requirements to form a complete connection plan, and intelligent control is also optional

2. Unit, realizing intelligent control unit, standardized design makes this product the most ideal choice for users when modifying and expanding substation schemes

Simple operation method

Each type of cabinet is equipped with a single line diagram of the circuit and an analog display that can display the internal components of the switch. The operating mechanism has a interlocking board that can ensure the rotation direction of the handle and correctly operate the equipment. Prevent misoperation, and provide step-by-step instructions on the cabinet door to ensure simple and safe operation

Structural characteristics

The cabinet body, door, and upper compartment are all treated with spray molding, and all cabinets are equipped with a main grounding busbar that can be connected to adjacent cabinets. All metal components, such as grounding switches and interlocking components, are connected to the grounding busbar. To ensure continuity, the components connected by screws are connected with copper braided tape. The rear of the cabinet is equipped with a pressure relief door to ensure that gas is discharged to the rear of the cabinet in case of internal combustion. The upper cover plate of the cabinet is fixed by screws and can be removed from the outside for busbar connection, The auxiliary device compartment on the upper part of the cabinet can be equipped with terminal boards and other small components, and relay protection can be achieved by raising the compartment.

The load switch and grounding switch adopt obstacle type interlocking, and the grounding switch and cabinet door adopt forced interlocking. Automatic interlocking can be achieved by following the following steps: closing the cabinet door, opening the grounding switch, closing the load switch, and separating each other, effectively avoiding misoperation

Operation safety of HXGN15-12 series switchgear

The professional structural design of the HXGN15-12 series switchgear ensures the safety of its operation

Divide the entire cabinet into 5 mutually insulated compartments

The interlocking mechanism is direct, reliable, simple, and easy to operate

Structural characteristics

1. Appearance

The shell is molded using cold-rolled steel plate or aluminum zinc coated sheet; Beautiful appearance, strong corrosion resistance, compact and reasonable structure, small size, and very convenient combination. There are five mutually insulated intervals within the frame, and two pressure relief ports are set at the back.

2. Easy installation

It can be freely combined, expanded, assembled, fast and simple according to various design requirements, with very simple installation and small footprint, and no special requirements for installation size.

3. Maintenance free

The switch has good sealing performance, and the SF6 insulation gas pressure meets the relevant regulations of IEC60298 standard. It operates safely and reliably, and is maintenance free.
