35kV armored removable switchgear KYN61 series

产品结构
Product Structure

KYN61-40.5开关柜结构按其组成可分为柜体、断路器手车两大部分。柜体内配用新型全绝缘真空断路器或进口六氟化硫断路器。柜体采用组装结构,提高了手车与柜体的配合精度,产品外形美观,能迅速组织生产、装配,能及时交货。柜体采用进口敷铝锌板经数控钣金设备加工折弯成型,通过高强度螺栓、螺母(8.8级)或拉铆螺母组装成型。

典型方案按功能特征可分为继电器仪表室、手车室、电缆室和母线室四部分,各部分按接地的金属板分隔,因此可阻止电弧延伸,从而使可能产生的故障限制在很小的范围内。除继电器仪表室外,其它隔室均有独立的泄压通道。当某一部分需要换元件或维修时,不需要全柜停电,只需要切断元件两端的电源,维修人员即可安全进入该室。其外壳保护等级为IP4X;断路器手车室门打开,断路器手车处于断开/试验位置时防护等级为IP2X。可实现闭门操作。开关柜的各项正常操作,包括断路器分合闸,断路器手车推到工作位置和退出到断开/试验位置以及接地的分合闸都能在高压隔室门关闭条件下进行。

开关柜具有电缆进出线、架空进出线母线联络、隔离、避雷器等其它一次方案。本开关柜采用复合绝缘,材料工艺完全立足于国内。


The Switchgear KYN61-40.5kV, according to the composition of its structure, can be divided into cabinets and the hand cart of the circuit breakers. Equipped in the cabinets are the novel fully insulated vacuum circuit breakers or imported sulfur hexafluoride circuit breakers. The switchgear is of assembly structure, which improves the apprearance quality and the fit precision of the hand cart and the cabinet. The product is beautiful in appearance and could be organized into rapid production, assembling and timely delivery. The Body of the switchgear adopts the imported aluminium and zinc coated plates manufactured and bended into form with CNC sheet metal equipment and assembled with high strength bolts and nuts (8.8 grade) or rivet nuts.

The typical program, according to functions, can be divided into the cabinets of relays and meters, hand cart, cables and buses. The four parts are separated according to the grounded metal plates so as to prevent the electric arc from extending and limit the possible faults in a small scope. The separated cabinets, except the relay and meter cabinet, are all equipped witn independent voltage relief channels. When some part needs replacement of components or maintenance, it is not necessary to shut down the power of whole cabinet. The only thing to do is to turn off the power at both ends of the component. The maintenance personnel can enter the cabinet safely. The protection level of the shell is IP4X. When the door of the hand cart is open and the hand cart is in the positions of breaking and test, the protection level is IP2X. A closed -door operation can be realized. Its normal operation, including the circuit breaker switch, the positions of the circuit breaker hand cart for working, test and isolation, the switch for grounding, can be carried out under the closed condition of the door for high-voltage circuit breakers cabinet. The switchgear has cables in and out, overhead lines, buses, insulations and lightning arrests. The composite insulation is adopted. The materials are entirely based on domestic technology.
