Product description:

The XGNC-12 type high voltage SF6 gas insulated metal clad switchgear adopts a modular design, and is perfectly unified with its fixed and flexible expansion to suit the requirements of end users or network nodes. It also meets the requirements of various power distribution switching stations, The needs of box-type substations and cable branch boxes have the characteristics of compact structure, safety and reliability, long life, and maintenance-free

XGNC-12 includes a gas box welded with 3.0mm stainless steel, in which all live parts and switch functions are placed.

Air insulated ring network cabinet is a term corresponding to compact gas insulated ring network cabinet. In the early days, air insulated ring network cabinets used VEI vacuum or compressed air load switches, gas producing load switches, and other ring network cabinets. Later, with the widespread use of SM6, it became the main stream of air insulated ring network cabinets. Like other air ring network cabinets, the load switch has been replaced with an SF6 air bag type, which means that the load and grounding three-position switch is installed inside an epoxy resin cast insulation shell. SF6 as arc extinguishing and insulation medium

Air insulated ring network cabinet - expandable SF6 ring network cabinet, can be freely combined, has a small size, is safe and reliable, and does not require maintenance.

SF6 gas is used as insulation and arc extinguishing medium, and the constant magnetic field arc rotation method ensures strong arc extinguishing ability, good breaking performance, low overvoltage, long electrical life, and maintenance free arc extinguishing chamber.

The load switch - fuse combination electrical appliance has a three position function, perfect sealing, reliable operating mechanism and locking.

The grounding switch has a short-circuit closing function.

The cabinet body is formed by stamping and bending with aluminum coated zinc sheet, which is sturdy and reliable.

96 hour salt spray test conducted by the institution.

The insulated busbar of the main busbar shall be separated by metal partitions between cabinets and shall not generate eddy currents. Both ends of the busbar shall be sealed with insulation sealing.

Measures to prevent electric field concentration and partial discharge shall be taken at the junction of main bus.

The fuse grading cover ensures the insulation performance of the switch cabinet, without electric field concentration and partial discharge.

The ring network cabinet includes the following intervals: switch interval, bus interval, cable interval, mechanism interval, and control protection interval

1) Load switch

Load switches have a certain on-load breaking capacity, which means they can be energized to open and close under light loads, but they cannot be operated frequently. Generally, load switches are equipped with fuses and have stronger arc extinguishing ability than isolation switches.

2) Isolation switch

When the circuit breaker disconnects the circuit, the disconnection of the isolation switch allows for a clear separation of the live and dead parts, serving as an auxiliary switch.

Due to the lack of intuitive external indicators for the contact position of circuit breakers, and in some cases, it cannot be guaranteed that its indication is consistent with the position of the contact, it is necessary to use isolation switches to clearly separate the energized and non energized parts.

In addition, the isolation switch has a certain natural arc extinguishing ability, which is commonly used for the input and disconnection of low current equipment such as voltage transformers and lightning arresters, as well as the connection between a circuit breaker and several devices, making the switching of the circuit breaker through the isolation switch more flexible and convenient.

3) Circuit breaker

A switching device that can close, carry, and disconnect the current under normal circuit conditions, and can close, carry, and disconnect the current under abnormal circuit conditions within a specified time.

4) Grounding switch

Mainly used for equipment maintenance, in order to prevent sudden power calls during the maintenance process, both ends of the maintenance equipment must be grounded.

The grounding switch of the high-voltage distribution cabinet is generally grounded on the output load side. When repairing the load side of the high-voltage distribution cabinet (such as tightening bolts, disassembling cables, etc.), we need to disconnect the switch and close the grounding switch of the distribution cabinet at the same time. This can prevent sudden power calls from causing electric shock accidents, and also discharge the remaining charge, which is beneficial for maintenance safety

Product advantages

1. Not affected by the environment

All the high-voltage live parts are located in the stainless steel box, the box shell is stainless steel sealed and welded, filled with SF6 gas with a working pressure of 1.4har, and the protection level is IP67. It can be installed in damp, sandy, dusty, salty, mine, box-type substation and any place where air pollution is prone to surface pollution flashover without special precautions. There is no need to clean the busbar and prevent small animals from cleaning up. Even the fuse compartment has an IP67 degree of protection. The extension bus is fully insulated and shielded

To ensure that it is not affected by changes in the external environment and maintenance-free

2. Highly reliable personal safety

All live parts are enclosed in the SF6 gas chamber, the switch has a reliable pressure relief channel, and has passed the internal arc test of 20kA/1s. The load and grounding switches are three-position switches, which simplifies the mutual interlock; cable compartment cover There is a reliable mechanical interlock between the board and the load switch, and the incoming unit can be installed with an arc extinguisher. This function can meet the needs of internal arc suppression. At this time, the switch does not need to be equipped with SF6 pressure relief channels.

3. Two options are provided for transformer protection

Load switch fuse combination electric appliance and circuit breaker with relay protection. Load switch fuse combination electrical appliances are used for transformers of 1600kVA and below, while circuit breakers with relays can be used for transformer protection of various capacities.

4. Environmental protection

Our company has passed the quality, environment and occupational health and safety management system certification of the China Quality Association. The research and development, manufacturing, operation and service of all products of the company strictly follow the system management documents and relevant laws and regulations, and continue to improve the quality, environment and Occupational health and safety management system;

The product uses environmentally friendly materials and adopts a zero-leakage cleaning process, and the product is sealed for life.
