October 16, 2020 Slide 11. Introduction to GIS (Gas Insulated Switchgear) Medium voltage (5-38 kV) gas insulated switchgear (GIS) differs greatly from the medium voltage AIS – Air insulated switchgear commonly used in North America Instead of using air and solid insulation materials, GIS switchgear has the vacuum interrupter and bare bus conductors in a sealed housing filled with an insulating gas. There is an interlock system between the switch disconnector (circuit breaker, disconnector) and the grounding switch, and between the grounding switch and the masking covers, which prevents incorrect switching procedures. the manufacturer can recycle used switchgears and safely remove the SF6 gas from the tanks. Eaton’s Power Xpert XGIS gas insulated switchgear is constructed with the majority of the medium-voltage parts fixed-mounted and contained in a laser-welded stainless steel SF6-filled tank suitable for withstanding harsh, corrosive environments. high protection rate, including arc protection – confirmed with appropriate certificates. GMA gas-insulated switchgear and controlgear with vacuum circuit-breaker has been designed for the various operating requirements in public and industrial medium-voltage distribution systems. About 15 years experience in Field Service catagory, I was been in many international projects for lead the site team and guide for Project Management and Clients about Gas Insulated Switchgear Systems. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas. GIS – Gas insulated switchgear (RMU) RING MAIN UNIT DR-6/DT-6.

Field of application Power supply companies • Transformer substations • Switching substations • Consumer substations • Distributed power generation Metering cubicle is not needed Sensors are small and weigh less than current instrument transformers (CT) and voltage transformers (VT) CTs and VTs weigh 18 -27 kg and sensors only 0.5 -2 kg I'm ready for your Medium Voltage GIS Installation Project. plastic sleeve, for example: YHAKXS, YHKX, XUHAKXS, XRUHKS. Figures 1-3 present the optional cable trays performance. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Isolator bushings are equipped with capacitive voltage dividers, which are connected to neon voltage indicators located on the front panel of the switchgear cubicles. SGC offers medium voltage switchgear up to 36kV, built to last. possibility to adjust the switchgear in order to cooperate with remote control and metering systems (for example, with SmartGrid networks). In the event of the fuse-link being burnt, the striker mounted on the link triggers the switching-off of the circuit breaker in the transformer bay. High-Voltage GIS (Gas Insulated Switchgear) Features Since the first operation of the phase segregated type GIS in 1970, Fuji has successfully developed as a standard series of phase segregated type or three phase encapsulated type GIS which realized a quite compact and very reliable construction.

On a deep level comparison, you need to weigh the upfront expenses of GIS an AIS against the needed lifelong maintenance. Closing of the switch disconnector in the transformer bay is possible only when the switch-fuse compartment door is closed. Tests have been carried out to confirm that insulation performance can withstand system voltage even if the gas pressure drops to atmospheric pressure *2. The IEEE C37.20.9 standard for gas-insulated switchgear was released in the summer of 2019, prior to this GIS … Medium Voltage Cable sealing end installation. It is a very economical solution for investors. The advantages of gas-insulated switchgear are: 1. Reduced switchgear weight. Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. Switch-fuse unit compartment High voltage thermally protected fuse-links (according to DIN 43625 standard) are installed in the switchgear switch-fuse unit compartment (in special isolating tubes). possibility to configure the switchgear from a range of different purpose bays: feeder, transformer, circuit breaker, metering, cable bays, easy switchgear expansion with other cubicles (this should be taken into account when the order is placed).
