适用范围Application Range

XGTZ7-12系列户内环保气体绝缘金属封闭开关设备(以下简称“环网柜”)是将各主回路开关密封在一个金属壳体内,以N2或干燥空气作为绝缘介质的一种成套电器,具有负荷开关柜(C柜)、真空断路器(V柜)二种基本功能单元柜,适用于12kV供电线路的环网供电或双辐射供电,特别适用于供电负荷密度大,用电缆馈电网络的工业商业区或农村乡镇,同时环网柜使用安全、无SF6气体,不受气候影响、安装容易、维修少,节省地方(占地小),很适合装于箱式变电站内。环网柜课通过扩展母线灵活组合。

XG2T7-12 Indoor environmental protection gas insulated metal-enclosed switchgear (hereinafter referred to as RMU) is a kind of complete equipment which seals all the main circuit switches in a metal enclosure using N2 gas or dry air as its insulating medium. It has two basic functional units, one is load switch cabinet (C compartment), the other unit is vacuum circuit breaker cabinet (V compartment). It is applied in the ring network power supply of 12kV power supply line or dual radiation power supply. Especially suitable for industrial and commercial area or rural area where required for high-density power supply load and cable feeder power grid. In addition, RMU is safe SF6-free, not affected by climate, easy installation, less maintenance and spate saving. It is perfectly suitable to install in a compact substation and can be flexibly combined by the busbar extension.

产品特点Product Features

绿色环保:采用N2或干燥空气作为主绝缘介质,无温室气体排放,产品生命周期后材料可回收90%以上。

环境适应性强:所有高压元件密封在充气的金属壳体内,因而绝缘性能稳定,特别适用于高海拔、严寒、潮湿、污秽等恶劣环境。

安全可靠:采用微正压力气体绝缘,防止水分渗入;在零表压下仍能安全可靠使用,设有和接地开关状态三工位开关观察窗,可直接地观察到隔离开关;高可靠的电气连接。

免维护:采用高寿命、免维护的真空灭弧室;高压绝缘件不受外界环境影响,不易老化。

经济性好:保留了SF6开关设备尺寸上的优势,减少对占地面积的需求,最大限度降低运行成本。

模块化设计:断路器(或负荷开关)+三工位隔离开关一体化设计;断路器机构与三工位隔离开关机构模块化、集成化设计;采用模块化插接技术实现各功能隔室或气箱间的电气连接,因而现场拼接安装方便,可灵活实现各种电气接线方案。

智能化:除基本的微机综合保护功能外,还可提供对气体的压力、温度、微水及电流、电压等数据的采集与检测功能,具有友好的操作界面。

小型化:产品外形尺寸(宽高深):400(500)mm*1640mm*860mm

易用性:具有上隔离和下隔离两种方案供用户选择,可实现电缆侧接地刀闸直接关合,符合电力部门“五防”操作规程,符合用户的使用习惯。

高电气参数:断路器柜额定电流可达1250A,开断31.5kA,海拔高度3000米以下。

Green and environment-friendly: It uses N2 gas or dry air as the main insulating medium, no greenhouse gas emission. The product material can be recycled more than 90% after the end of its life cycle.

Strong environmental adaptability: A11 high-pressure components are sealed in the inflatable metal enclosure, thus it has the stable insulation performance, especially for high altitude, cold, humid, dirty and other harsh environment.

Safe and reliable: It adopts the micro-positive pressure gas insulation to prevent moisture infiltration; It can sti11 be safe and reliable under the zero gauge pressure; Equipped with three-position switch observation window. The status of disconnector and earthing switch can be observed directly; High reliability electrical components.

Maintenance-free: The vacuum interrupter has a long service life and maintenance-free; The high voltage insulating parts are not affected by the external environment, and aging-resistant.

Economic: It retains the size-advantage of SF6 switchgear to reduce the space requirement and minimize the operating cost.

Modular Design: Circuit breaker (or load switch) and three-position disconnector are designed integrally; Circuit breaker mechanism and three-position disconnector mechanism are modular and intergrated design; It adopts modular plug-in technology to realize the electrical connection between each functional compartments or air boxes,thus it is very convenient for the on-site installation, and very flexible to realize different types of electrical wiring diagrams;

Intelligentize: besides the basic microcomputer integrated protection function, lt also can provide data collection and detection functions for gas pressure, temperature, micro-water and current, voltage etc., and has a friendly interface.

Miniaturize: Product Overall Dimension (width*height*depth):400(500)mm*1640mm*860mm.

Availability: It offers two options of upper isolating and lower isolating for users to choose. It can realize cable-side earthing switch directly to close, It complies with the "five-prevention" operating procedures put forward by Ministry of Power, also in line with the user's operating habits.

High electrical parameter: circuit breaker cabinet with rated current up to 1250A, breaking current 31.5kA and altitude lower than 3000 meters.
