摘要：本次畢業(yè)設(shè)計(jì)的主要內(nèi)容是對(duì)煤礦礦井供電系統(tǒng)移動(dòng)變電站、輸電線路的初步設(shè)計(jì)，根據(jù)煤礦供電系統(tǒng)相關(guān)要求規(guī)范進(jìn)行設(shè)計(jì)。 移動(dòng)變電站是煤礦礦井電力系統(tǒng)的重要組成部分，擔(dān)負(fù)著改變電能和分配電能的重要任務(wù)。移動(dòng)變電站的優(yōu)點(diǎn)在于它的移動(dòng)性，它能隨著井下煤礦開采而深入，及時(shí)有效的為井下采煤作業(yè)提供所需電能，減小損耗和壓降，保障了煤礦生產(chǎn)的安全性與有效性。 輸電線路是煤礦礦井電力系統(tǒng)的重要組成部分，擔(dān)負(fù)著輸送和分配電能的重要任務(wù)。輸電線路能否穩(wěn)定運(yùn)行決定了整個(gè)電力系統(tǒng)的穩(wěn)定運(yùn)行。改進(jìn)供電質(zhì)量，力求供電最為安全、可靠、方便、靈活、經(jīng)濟(jì)，變配電治理更為有效，從而改善供電質(zhì)量，使該電力系統(tǒng)更安全、可靠的運(yùn)行。 設(shè)計(jì)首先根據(jù)任務(wù)書所給參數(shù)及任務(wù)：①給定條件：進(jìn)入該煤礦的地面電壓為35kV；井下高壓電纜的長(zhǎng)度為：1km ；以及煤礦現(xiàn)有的設(shè)備分布圖及類型；②設(shè)計(jì)任務(wù)：電氣主接線設(shè)計(jì)、電纜的選擇、保護(hù)設(shè)計(jì)、各設(shè)計(jì)圖紙的繪制。在設(shè)計(jì)可行的條件下，按照任務(wù)書依次完成各項(xiàng)設(shè)計(jì)任務(wù)。 關(guān)鍵詞：移動(dòng)變電站；防塵防爆 ；防火
ABSTRACT:The main content of this graduation paper is the designs of movable transformer pack, transmission line as well as protective system of power-supply of coal mine, according to the request and standard of power-supply of coal mine. Movable transformer is an important part of power-supply of coal mine, which bears the important task of electricity transmission and distribution. Its advantage is that it is removable and it along with an in-depth shift of coalmine exploitation. Provide timely and effective support electricity needed by coalmine exploitation to decrease power loss and voltage drop. It ensure it is safe and availability production in coal mine. Transmission line is an important part of the electricity system, which bears the important task of electricity transmission and distribution. The stability of the entire power system operation depends on the stable operation of transmission lines. Trying to make the supply most secure, reliable, convenient, flexible, economic, and make the power distribution management more effective in order to improve power quality and reduce operating costs. The design is made in accordance with the parameters and tasks of the letter. First, entering to surface power voltage is 35kV, the length of inside high-voltage cable is 1km and it offer a existing distribution map of facilities as well as device type; Second, the design tasks are electric main wiring design, short circuit current calculations, electrical equipment selection, cable selection, relay protection design, the design drawings of the drawing, control system design. Then, analyzing its feasibility and finishing all tasks on the condition that the design is feasible. Keywords: Movable transformer pack; dustproof explosion-proofing;fire
