HXGN15-12(SF6）type single unit ac metal closed ring network switch equipment (hereinafter referred to as ring network cabinet) is a new generation of high-voltage electrical products that we have successfully designed and developed by ourselves in accordance with the requirements of domestic agricultural electricity and urban network transformation by introducing foreign advanced technology.All the technical performance indicators meet iec62271-2003:2003 and GB3906 standards.
Main switch, operating mechanism and components of ring network cabinet adopt original parts of ABB or fl-12/24 switch equipment assembled and produced domestically with imported parts. It can also be equipped with original HAD/US SF6a circuit breaker of ABB or vd4-s vacuum circuit breaker according to user needs. The operation mode can be divided into manual and electric.
The cabinet is made by numerical control machine after machining, the protection grade reaches IP3X, and it has reliable mechanical interlock and anti-misoperation function.This product has the characteristics of small size, light weight, beautiful appearance, easy operation, long life, high parameters, no pollution, little maintenance and so on.
Hxgn15-12 (SF6) single unit ac metal closed ring network switching equipment, suitable for the ac 50Hz, 12kV power network, as the acceptance and distribution of electrical energy.
HXGN15-12(SF6）型单元式交流金属封闭环网开关设备（以下简称环网柜）是我们在引进国外先进技术并按照国内农电及城网改造之要求而自行设计、 研制成功的新 代高压电器产品。各项技术性能指标全部达到IEC62271-200:2003和GB3906标准。
环网柜的主开关、操作机构及元器件采用ABB公司原装件或采用进口部件国内组装生产的SFL-12/24型开关设备， 也可根据用户需要配装ABB公司原装HAD/US型SF6a 断路器或VD4-S型真空断路器， 其操作方式分为手动、电动两种。
柜体经数控机床加工后柳接而成，防护等级达到IP3X，并有可靠的机械联锁和防误操作功能。本产品具有体积小、重量轻、外形美观、操作简便、长寿命、高参数、无污染、少维护等极具显著的特点。
HXGN15-12(SF6）型单元式交流金属封闭环网开关设备， 适用于交流50Hz、12kV的电力网络中， 作为电能的接受和分配之用。

Cabinet structure
The cabinet body of ring network adopts 2 "nm thick aluminum coating board (or cold-rolled plate sprayed with plastic) to form, and there are two pressure release holes behind the cabinet, one for the cable room and the other for the load switch/bus room. This structure can maximize the safety of people and the reliability of operation equipment.
Delta compartments
Bus room bus room is located at the top of the cabinet and connected with adjacent switch cabinets.
The load switch is an independent unit, filled with SF6 gas.
3. About 75% of the cable room space is used for cable connection, fuse, grounding switch and CT and PT installation.
4. Mechanism compartment and interlock
The cell contains operator mechanism and mechanism interlocks as well as position indication, auxiliary contact, trip coil, live display and interlocks.
5 relay box
The relay box is on top of the cabinet and is optional.Chambers are used to install special devices such as meters, relays, and motor units.
A circuit breaker (SD6 or vacuum) can be placed under the load switch.
Stress release
1. Top pressure release
The above is used to release the gas pressure caused by arc accidents in bus and load switch rooms.
2 pressure release at the bottom
The following is used to release the gas pressure caused by the arc accident in the cable cubicle.
