空气压缩机站监控预警装置
摘要：
一种空气压缩机站监控预警装置，其特征在于：在空压机供气管路上端分别安装数显型压力开关，预警箱上的声光报警灯(XD1、XD2、XD3)通过导线与测试箱上的测试按钮(SB1、SB2、SB3)的常开触点和自锁按钮(S1、S2、S3)的常闭触点分别串联联接；断路器(QF)的出线(1)、出线(2)分别并联联接电源指示灯(HL)自锁按钮(S1、S2、S3)的常闭触点、测试按钮(SB1、SB2、SB3)的常开触点；数显压力开关(YK1、YK2、YK3)和测试按钮(SB1、SB2、SB3)内继电器常开触点分别并联联接。
摘要（英）：

The invention discloses a monitoring early-warning device for an air compressor station, which is characterized in that the air supply lines of an air compressor are respectively provided with numeric display pressure switches; acousto-optic alarm lamps (XD1, XD2, XD3) arranged on an early-warning box are respectively connected with normally open contacts of test buttons (SB1, SB2, SB3) and normally closed contacts of locking-press buttons (S1, S2, S3) in series, and the test buttons and the locking-press buttons are arranged on a test box; the outgoing line (1) and the outgoing line (2) of a breaker (QF) are respectively in parallel connection with the normally closed contacts of the locking-press buttons (S1, S2, S3) of a power indicator (HL) and the normally open contacts of the test buttons (SB1, SB2, SB3) of a power indicator (HL); and the numeric display pressure switches (YK1, YK2, YK3) are respectively in parallel connection with the normally open contacts of relays in the test buttons (SB1, SB2, SB3).
