【摘要】：煤礦井下惡劣的環(huán)境,正是由于井下有著大量的爆炸性氣體和煤塵,這就要求煤礦井下所有電氣設(shè)備都必須具有防爆性能。本文研制的組合開(kāi)關(guān)就是根據(jù)GB3836-2010標(biāo)準(zhǔn)設(shè)計(jì)、開(kāi)發(fā)、研制出來(lái)的。 本課題的研究主要分為四部分,第一部分是組合開(kāi)關(guān)標(biāo)準(zhǔn)的確立和問(wèn)題的提出,第二部分是組合開(kāi)關(guān)防爆外殼的設(shè)計(jì),第三部分是電氣設(shè)計(jì)和PLC程序的編寫(xiě),第四部分是各項(xiàng)性能的試驗(yàn)。 在防爆外殼的設(shè)計(jì)中,運(yùn)用了Solidworks軟件以及其中的simulation模塊,并且進(jìn)行了模型簡(jiǎn)化,運(yùn)用了網(wǎng)格控制和網(wǎng)格劃分,最后進(jìn)行了仿真分析,得出了防爆外殼的應(yīng)力分布圖和位移圖。給組合開(kāi)關(guān)外殼的設(shè)計(jì)提供了參考依據(jù)。 在電氣原理設(shè)計(jì)和PLC程序的編寫(xiě)中,首先在總體上提出了控制方案,并以此為據(jù)設(shè)計(jì)出了電氣原理圖。根據(jù)“煤礦安全規(guī)程”規(guī)定：組合開(kāi)關(guān)所具有的保護(hù)功能主要包括：漏電保護(hù),過(guò)載保護(hù)、短路保護(hù)、斷相保護(hù)、欠壓保護(hù)和過(guò)壓保護(hù)。根據(jù)各種不同保護(hù)的具體要求,進(jìn)行梯形圖程序的編寫(xiě)。核心的中央控制單元選用了KC02-MD礦用本安模塊化可編程控制器。 在試驗(yàn)部分,主要是依據(jù)標(biāo)準(zhǔn)要求,完成了組合開(kāi)關(guān)的各項(xiàng)性能試驗(yàn),包括各種試驗(yàn)數(shù)據(jù)、圖表、界面等。 本文研發(fā)的組合開(kāi)關(guān)是根據(jù)GB3836.2-2010標(biāo)準(zhǔn)設(shè)計(jì)的,經(jīng)試驗(yàn),符合國(guó)家標(biāo)準(zhǔn)要求。
[Abstract]:It is precisely because there are a lot of explosive gas and coal dust in the coal mine that all electrical equipments must have explosion-proof performance. The combined switch developed in this paper is designed and developed according to GB3836-2010 standard. Developed. The research of this subject is mainly divided into four parts. The first part is the establishment of the standard and the problem of the combination switch, the second part is the design of the explosion-proof shell of the combination switch, the third part is the electrical design and the writing of the PLC program. The fourth part is the performance test. In the design of explosion-proof shell, Solidworks software and simulation module are used, and the model is simplified, grid control and grid division are used. Finally, the simulation analysis is carried out. The stress distribution and displacement diagram of the explosion-proof shell are obtained, which provides a reference for the design of the combined switch shell. In the design of electrical principle and the programming of PLC program, the control scheme is put forward as a whole. According to the regulations of Coal Mine Safety Code, the protective functions of the combined switch mainly include: leakage protection, overload protection, short circuit protection, phase break protection, Undervoltage protection and overvoltage protection. According to the specific requirements of various kinds of protection, the trapezoidal diagram program is compiled. The central control unit of the core adopts KC02-MD modular programmable controller for mine safety. In the test part, according to the standard requirements, the performance tests of the combined switch are completed, including all kinds of test data, charts, interfaces and so on. The combined switch developed in this paper is designed according to GB3836.2-2010 standard.
