摘要:工廠供電，就是指工廠所需電能的供應和分配，亦稱工廠配電。電能是工廠的主要能源和動力，做好工廠供電對于實現(xiàn)生產(chǎn)過程自動化，增加產(chǎn)量，提高產(chǎn)品質(zhì)量，提高勞動生產(chǎn)效率，降低生產(chǎn)成本有著極其重要的意義。 針對我校目前情況，工學院學生每年都要外出實習，不僅要耗費大量資金而且給學校和學生造成許多麻煩，因此工學院應該建設自己的實習工廠。工廠實習的意義在于，使學生掌握供配電系統(tǒng)的管理和運行技能，為學生今后從事供配電技術(shù)工作奠定基礎。 結(jié)合本專業(yè)相關知識，如《工廠供電》、《電力系統(tǒng)繼電保護》等，能進行設計的為該實習工廠的供配電系統(tǒng)的電氣設計。初步的設計思路是：首先是對實習工廠的負荷進行計算并且設計功率補償裝置；根據(jù)計算的負荷再選取合適的變壓器，并確定主接線方案；其次再進行短路電流的計算進行一次設備的選型；然后對變壓器和線路進行了繼電保護的整定和計算；最后對變配電所接地電氣裝置進行了簡單的設計。 關鍵詞：工廠配電，繼電保護，負荷計算，短路電流，一次設備
Abstract:The factory power supply, is refers to the factory for electricity supply and distribution, also known as the factory distribution. Electric energy is the main plant energy and power, to power plant for the realization of the production process automation, increase production, improve product quality, improve labor productivity, reduce the production cost is very important. According to our current situation, college student every year to go practice, not only to spend a considerable amount of money but also for schools and students to cause a lot of trouble, the institute should build their own internship factory. Factory practice significance lies in, to enable students to master the distribution system for management and operation skills, for the students engaged in technical work laid the foundation for distribution. Combined with the professional knowledge, such as" power plant"," electric power system relay protection", can be designed as the practice facility for distribution of the electrical system design. Preliminary design train of thought is: first is to practice factory load was calculated and the design of power compensation device; based on the calculation of the load to choose an appropriate transformers, and to determine the main wiring scheme; and secondly to short-circuit current calculation for a selection of the equipment; and then on the transformer and the circuit of relay protection and calculating; at the end of the substation grounding of electrical apparatus are a simple design. Key words: power distribution, relay protection, load calculation, short circuit currentan equipment |
