Industrial High Voltage Gas Insulated Ring Main Unit

The FYG-12 type SF6 metal-sealed and fully insulated series ring network switchgear has passed the type test of the National Occlusion Electrical Testing Center. Widely used in 10KV/6K power distribution system, it is the first choice switch product for various users in urban and rural areas.

The switch cabinet is a modular unit model, which can be combined according to different purposes. Through the combination of fixed units and expandable units, the substation can meet the flexible use of compact switch cabinets.

Inflatable ring cabinet FYG-12 is divided into non-extended standard configuration and extended standard configuration. Due to the combination of full modules and half modules and its own scalability, it has extremely special flexibility. FYG-12 inflatable ring cabinet implements GB standard. The design life of operation under indoor conditions (20℃) exceeds 30 years.

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
