DXG-12 Indoor AC HV Gas Insulation Switchgear (hereafter referred to as "GIS") is a new generation of switchgear. The main switchgear can adopt vacuum circuit breaker of permanent magnet mechanism or vacuum circuit breaker of spring mechanism. It adopts air insulation and SF6 compartments, which makes the space inside the GIS is not only compact, but enough to enlarge. It is suitable for power distribution automation. The GIS is featured by compact structure, flexible operation and reliable interlock etc. It is suitable for varieties of places (especially for bad condition) and it provides different request of customers with different technical scheme. It satisfies the customer's requirement with sensor technical performance, the latest protection relay in addition to advanced technical performance and flexible and light assembly scheme. It is widely used in miniature secondary substation, switching station, combined substation, residential area, industrial and mining business and malls, especially suitable for airport, underground and railway and other places where electricity power is in need largely.
Service ambient conditions:
A. Air temperature: Max: +40º C, Min: -25 º C(average value<= 35 º C within 24 hours)
B. Altitude: <= 3000m (if exceed 3000m, please negotiate with the manufacturer)
C. Air humidity: Daily average relative humidity <= 95%, monthly average relative humidity <= 90%;
D. The range of induction electromagnetic interference in secondary system <=1.6kV.
The compartments of GIS use 3-5mm corrosion resistance plates, which are firstly processed by digit-controlled lathe and then welded by welding robot, with the advantage of less amount of deformation, good seal. Other compartments are made of high quality cold rolled sheets, which firstly bent and then welded, with the characteristics of high accuracy and intensity. The functional units are separate module, so it is convenient for assembly. Besides the sealed compartments in the GIS have separate pressure release passages, which ensure the safety of the personnel and equipments.
The universal technical requirements of GB11022-1999 HV Switchgear and control equipment standards GB/3906-1991 3-35 kV AC Metal-clad Switchgear.
C. Protection degree:
IP 67 of gas insulating compartments, IP4X of LV switchgear.
Please provide the following materials while ordering:
A. Primary wiring scheme and single busbar system diagram
B. Secondary control principle diagram or wiring diagram terminal pareto diagram
C Layout plan of switchgear.
D. Detailed type, specification, quantity of electric components inside the switchgear.
E. If without any request for the material and specification of busbar from customers, they will come up with manufacturer'requirement.
F. If the switchgear is used in special environmental condition, it should be marked while ordering.
G. Wiring scheme of major loop.
H. The principle diagram of auxiliary circuit and control circuit of GIS and other written materials requested.
