▒   概述 SUMMARY

KYN61-40.5 型铠装移开式交流金属封闭开关设备系三相交流 50Hz、额定电压 24kV 的户内成套配电装置。作为发电厂、 变电站及工矿企业接受和分配电能之用，对电路起到控制、保护和监测等功能。

KYN61-40.5 armoured removable AC metal enclosed switchgear is a complete set of indoor distribution equipment with three-phase AC 50Hz and rated voltage of 24kV. As a power plant, substation and industrial and mining enterprises, it can receive and distribute electric energy and control,protect and monitor circuits.

▒   结构说明 STRUCTURE DESCRIPTION

开关柜按 GB3906 和 IEC62271-200:2003 要求进行设计。整体由柜体和可抽出部分（手车）两部分组成，柜体结构均采用敷铝锌板用螺栓栓接组装成型，用金属隔板将开关柜内部分隔为断路器室、主母线室、电缆室和继电器仪表室，并且金属构件均可靠接地，主回路系统的各隔室均有独立的压力释放通道，在电缆室内可设置 10x60mm 的接地母线。

The switchgear is designed according to the requirements of GB3906 and IEC62271-200:2003. The whole cabinet consists of two parts: cabinet and extractable part (handcart). The cabinet structure is formed by bolting and assembling aluminum-coated zinc plates. The interior of the switch cabinet is divided into circuit breaker room, main bus room, cable room and relay instrument room by metal partition boards, and all metal components are reliably grounded. Each compartment of the main circuit system has independent pressure release channels, and a 10x60mm grounding bus can be set in the cable room.
