XGN2B-12 box fixed AC metal enclosed switchgear


XGN2B-12(Z) box-type AC metal closed switchgear is a three-phase AC 50Hz high voltage switchgear set. It is used for 10kV system to receive and distribute electric energy and realize circuit control and protection. It is the characteristic product of "Zhengchao" in Guangdong. Widely used in large and medium-sized power plants, 110kV ~ 500kV substations, distribution areas and high-rise buildings and other power users, has won the "; Guangdong Province Excellent New Product Award" . The new generation of products meet the latest requirements of users, with the characteristics of metal spacer switchgear. The equipment cabinet is equipped with VS1 and other vacuum circuit breakers, and has passed a full set of type tests according to the new standard, the most stringent requirements. Through the internal fault arc test of 31.5kA/0.5s, through the temperature rise test of 1.1 times rated current under the premise of the same size of the cabinet, the important technical innovation of low temperature rise, high strength, arc resistance, high altitude and intelligence has been realized. Product quality safety, stability, by the majority of users trust and praise.



◇ Structure, performance and characteristics of switchgear ◇


Cabinet body for metal closed assembly fixed structure, structural strength to meet the use of IAC class requirements. In typical scheme, the cabinet is equipped with relatively independent circuit breaker room, bus room, cable room and instrument room. Between rooms and between cabinets are separated by grounded metal plates, which can ensure safe operation. The circuit breaker room and the bus room are provided with independent pressure relief channels. When the fault arc occurs in the cabinet, the arc gas will be discharged from the top of the cabinet. Switchgear has perfect and reliable, unique anti-error mechanical interlocking device: "prevent misdivision, misoperation circuit breaker", "prevent with load disconnecting isolation switch", "prevent with grounding switch (or grounding wire) power transmission", "prevent live grounding switch (or hanging grounding wire)", "prevent stray live interval" etc. The "five defenses"; Function; According to the specific requirements of users, mechanical and electrical double locking and interlocking function can be realized to prevent the occurrence of electrical misoperation accidents. Cable room construction and maintenance is convenient, can connect a number of cables. The switchgear is equipped with a perfect and reliable grounding system. The metal frame of all primary electrical appliances is connected to the grounding bus with copper bar, which can ensure the continuity of grounding and the safety of operation and maintenance.
