插入式二元差动继电器
产品简介:
Ø 产品主要功能:
用于交流50Hz电气化区段和非电气化区段站内不对称高压脉冲轨道电路中,在轨道电路接收端作为轨道继电器使用,能够可靠地反映轨道区段的占用和出清。
插入式二元差动继电器由电磁系统(铁心、极掌、轭铁、衔铁、支板、线圈等)和接点系统(静接点、动接点等)、底座、外罩等主要部件组成。
Ø 产品主要特点:
结构为双闭磁路且具有磁分路结构的拍合式二元直流电磁继电器,继电器有四个铁心柱、八个线圈,构成差动继电器头部圈和尾部圈。
继电器为直流电磁继电器,采用重力恒定原理,在线圈断电时,强制动合接点断开,符合故障导向安全原则。
继电器对工频和对称的其它波形都具有很强的抗干扰能力。
Ø 产品外型尺寸:继电器尺寸:197mm×115mm×166mm (长×宽×高);
继电器插座尺寸:166mm×115mm×22mm (长×宽×高)。
Ø 产品安装方式:
应安装于配套插座上, 继电器插座安装在组合柜(架)上,将继电器水平插入插座,并用自带的锁紧螺杆与插座锁紧。
