5、标准JB/T巧74一92工业自动化仪表盘用接线座代替JB1574一75本标准参照采用国际IEC947-7-1《低压开关与控制设备辅助设备铜导线接线座》(1989年版)。I主题内容与适用范围本标准规定了工业自动化仪表盘用接线座(以下简称接线座)的一般规则和基本要求。接线座主要用于工业自动化仪表盘内外仪表和信号系统以及电保护装置的导线连接。本标准适用于额定电压不超过500V,连接圆铜导线截面不大于2-5mm'的各种型式接线座。接地型接线座的连接圆铜导线截面为6mm',在制订各类接线座的产品标准时,除需符合本标准的要求外,还应对产品本
6、身所具有的特殊要求作出具体的规定。2引用标准GB1497低压电器基本标准GB5169.4电工电子产品着火危险试验灼热丝试骏方法和导则GB4207固体绝缘材料在潮湿条件下相比漏电起痕指数和耐漏电指数的侧定方法GB2423电工电子产品基本环境试骏规程GB2828逐批检查计数抽样程序及抽样表(适用于连续批的检查)GB2829周期检查计数抽样程序及抽样表(适用于生产过程稳定性的检查)ZBY003仪器仪表包装技术条件3术语31〔接线)端子terminal用来与外部电路进行电连接的导电部件。32绝缘件insulator为保持端子的位置或为保
7、护端子绝缘的部件。33端子组件terminalassembly二个或多个组成同一导电部件的端子。34接线座terminalblock由一个或多个相互绝缘的端子或端子组件所组成的接线器件。35安装轨mountingtrack用于对接线座作固定、移动或重新排列的部件。4产品分类接线座技其用途可分为a.基型;卜联络型;机械电子工业部1992-05一27批准1993-04一01实施JB/T1574一92a试验型:d.试验联络型;e.固定电阻型;f·可调电阻器型;S-开关型;h-熔断器型;f.接地型;J-零线或中性线型;k-特殊型。5正常
8、工作条件5.1环境温度a.环境温度上限为551C.b-环境温度下限为一25'C接线座预期用于环境温度上限超过55℃的条件时,用户应向制造厂申明。5.2相对湿度:69096,5-3污染等级:对接线座推荐采用GB1497中4-5-3条规定的污染等级305-4大气压力
