概述Overview
适用于三相交流50Hz额定电压为35kV最高工作电压40.5kV的户内电力系统中，作为发电厂，变电所等工矿企业配电室接收分配电能用，并对电路具有控制保护和测量等功能，还可使用于具有频繁操作的电力线路中。该 产品根据CB3906-91《3-35kV交流金属封闭开关设备》和DL404-91的标准，并参照EC-289国际标准的要求 研制的其主要特点:是体按金属封你式结构设计，其外防护等级为IP2X柜内配有性能优息的真空断路器，即ZN12-35,它采用引进西门子公司技术制。Cl-0合金头材料加工，生产工艺独特，开新短路电流能力强截流值小，耐电腐蚀，电场分布均匀。由于断路器可靠性高，可以大大减少停电检修时间和次数。
Suitable for indor three-hase 50-2 AC power system with 35kV n rated vo tage and 40 5kV in maximum operating votage. it appies to power distribution rooms of power plants,subsiations and industrial and minind enterprises o receive and distribute electic eneray, Wth contro, protection and monitoring functions, t alo appiles to pover crcuits with frequentoperation. The product is researched and developed based on recuirements of AC Meta-endlosed Switchgear for ated Votages of 3-35kV (CB3906-91), DL404-91 and lEC-289ntematona sandard. And ts ma characterstics incude that its cabine s desianed dased on meta-encosed voe structure. protecion orade of ts encosure is ip2x, and vacuucircut breaker with god performace is provided in the cabinet, ie.ZN12-35. Adopting technology of Siemens and processing of Cu-Cr aloy contact materal, itfeatures uniqueproducion process. strono canabilivy of breakin shor-circuit curent, smal cu-of value. electrocorosion resisance and even distribution of electic ield. Due to hich relabity oicircuit breaker, power outage and maintenance duration and freauency can be reduced areatly.
并且该柜运行方案齐全，有单母线运行方式及旁路母线运行方式，能实现不间断供电。该柜采用空气绝缘，其五防性能齐全是当今固定式开关柜的首选柜型之一。
Besides, the switchgear has complete operaton proposals as wel as single and bypass bustbar operation modes, capable of realizing uninterupted power supply, With ar insuiationand five-prevention performance.the switchaearone of preferred tvpies of stationary tvpe switchaear currently.
