摘要:礦用隔爆型低壓饋電開關(guān)是煤礦配電系統(tǒng)的關(guān)鍵環(huán)節(jié),其好壞直接影響著煤礦井下生產(chǎn)安全和生產(chǎn)效率。而低壓饋電開關(guān)的智能化程度主要取決于保護(hù)系統(tǒng)的可靠性和靈敏性。本設(shè)計(jì)研制的井下低爆綜合保護(hù)器,依據(jù)MT871-2000《礦用隔爆型低壓交流真空饋電開關(guān)》標(biāo)準(zhǔn),能對低壓電網(wǎng)中出現(xiàn)的短路、過載、過壓、欠壓、漏電等故障進(jìn)行實(shí)時檢測,并有方便的兩鍵參數(shù)設(shè)定和全中文液晶顯示功能。通過對井下低壓供電不同方式的深入研究,本設(shè)計(jì)較好地解決了功率方向型漏電的誤動作和拒動作問題,以及短路、漏電等故障的越級跳閘的問題。關(guān)鍵詞:漏電;低壓電網(wǎng);綜合保護(hù)器;單片機(jī)

設(shè)置復(fù)位標(biāo)志位便于區(qū)分不同原因引發(fā)的復(fù)位，作為一種新技術(shù)被越來越多的新型單片機(jī)所采納。例如Philips公司的P87LPC700和 P89LPC900系列、Freescale公司（原Motorola半導(dǎo)體部）的MC68HC05系列和MC68HC08系列、Sunplus公司的 SPMC65系列、Microchip公司的PIC系列等，內(nèi)部都設(shè)計(jì)了專門用于記錄各種復(fù)位標(biāo)志的狀態(tài)寄存器。MC68HC08系列有一個復(fù)位狀態(tài)寄存器，負(fù)責(zé)記錄6種復(fù)位標(biāo)志位：上電復(fù)位、引腳復(fù)位、看門狗復(fù)位、非法指令復(fù)位、非法地址復(fù)位和欠壓復(fù)位。SPMC65系列有一個系統(tǒng)控制寄存器，負(fù)責(zé)記錄5種復(fù)位標(biāo)志位：上電復(fù)位、外部復(fù)位、看門狗復(fù)位、非法地址復(fù)位和欠壓復(fù)位。51兼容的P89LPC900系列有一個復(fù)位源寄存器，負(fù)責(zé)記錄6種復(fù)位標(biāo)志位：欠壓復(fù)位、上電復(fù)位、外部復(fù)位、看門狗復(fù)位、軟件復(fù)位和UART收到間隔字符復(fù)位（主要作為進(jìn)入ISP監(jiān)控程序的途徑之一）。就連初學(xué)者很常用的 AT89S51/52和P89C52X2，也在其電源控制寄存器PCON中增設(shè)了一個上電標(biāo)志位POF。1、 復(fù)位標(biāo)志位的設(shè)置方法傳統(tǒng)的80C51單片機(jī)沒有設(shè)計(jì)復(fù)位標(biāo)志位的記錄功能，這應(yīng)該說是一種遺憾，那么能否通過一定的技術(shù)手段來彌補(bǔ)這個缺憾呢？這里給廣大80C51單片機(jī)用戶提供一種啟示和引導(dǎo)。實(shí)現(xiàn)復(fù)位標(biāo)志位的記錄肯定需要一定的硬件電路支持，而這種電路的設(shè)計(jì)不存在固定模式。筆者利用一片MAX813L設(shè)計(jì)了一種支撐電路，如圖1所示，僅供讀者參考。
