10kV環(huán)網柜部件測繪重構及組件制造工藝設計

摘要：為提高供電可靠性，使用戶可以從兩個方向獲得電源，通常將供電網連接成環(huán)形。這種供電方式簡稱為環(huán)網供電。在工礦企業(yè)、住宅小區(qū)、港口和高層建筑等交流10KV配電系統(tǒng)中，因負載容不大，其高壓回路通常采用負荷開關或真空接觸器控制，并配有高壓熔斷器保護。該系統(tǒng)通常采用環(huán)形網供電，所使用高壓開關柜一般習慣上稱為環(huán)網柜。環(huán)網柜除了向本配電所供電外，其高壓母線還要通過環(huán)形供電網的穿越電流（即經本配電所母線向相鄰配電所供電的電流），因此環(huán)網柜的高壓母線截面要根據本配電所的負荷電流于環(huán)網穿越電流之和選擇，以保證運行中高壓母線不過負荷運行。目前環(huán)形柜產品種類很多，如HK-10、MKH-10、8DH-10、XGN-15和SM6系列。
環(huán)網柜出現(xiàn)的時間不算長，但近年以來卻得到了廣泛的使用，這主要是由于新發(fā)展起來的工業(yè)企業(yè)和事業(yè)單位的建筑物，從供配電的角度來看，以中，小型容量為大多數其配電變壓器一般不超過1250KVA，長期穩(wěn)定供電，高壓開關不頻繁操作。對于這類用戶，環(huán)網柜的性能雖不是最完美的，但卻是足夠的，可以勝任的。隨著大規(guī)模的城市建設，大量大型高層建筑物拔地而起，變配電所往往就設在樓下，根據消防要求，變配電設備必須“無油化”，根據建設面積的合理使用，變 配電設備應該“小型化”，于是環(huán)網柜或真空斷路器，干式變壓器，干式互感器就進入了幢幢大樓。環(huán)網柜結構簡單，運行可靠且安全，維修量很小，運行費用低，比起裝有斷路器的開關柜，優(yōu)勢很突出。環(huán)網柜要求負荷開關具有更高的性能和更小的體積，新型的負荷開關應運而生，這又反過來帶動了環(huán)網柜的技術進步，當今 的環(huán)網柜不但性能優(yōu)良而且系列化了，這更擴展了環(huán)網柜的使用范圍。

Abstract：To improve the reliability of power supply, so that users can get the power from two directions, usually for grid connected in a ring. This power supply power for short ring. In the mining industry, residential areas, ports and high-rise buildings such as AC 10KV distribution system, the load capacity is not due to its high voltage circuit usually load switch or vacuum contactor control, and is equipped with high-voltage fuse protection. The system typically uses a ring network power supply, known as the High Voltage Switchgear RMU general habit to use. RMU In addition to the distribution of the power supply, but also through its high-voltage bus through the ring for the current grid (ie, the distribution of the bus by the current supplied to the substation adjacent), so high-voltage bus RMU according to the cross-sectional distribution of the load current in the ring currents chosen to ensure that the operation of the high voltage bus-load operation, however. Currently many types of ring counter products, such as HK-10, MKH-10, 8DH-10, XGN-15 and SM6 series.
It is not long that the RMU appeared .but in recent years has been widely used, mainly due to the newly developed industrial enterprises and institutions of the building, from the perspective of supply and distribution to small and medium sized most of its distribution transformer capacity is generally not more than 1250KVA, long-term stable supply, high voltage switch infrequent operation. For such users, RMU performance, while not perfect, but it is enough, you can do it well.With large-scale urban construction, a number of large high-rise buildings going up, and substation is located downstairs, according to the fire safety requirements, power distribution equipment must be "non-oil", according to the construction area of fair use , power distribution equipment should be "downsized", so RMU or vacuum circuit breakers, dry-type transformers, dry type transformers entered the building blocks. RMU simple structure, reliable operation and safety, a small amount of maintenance, low operating costs, compared to the circuit breaker switchgear equipped advantage very prominent. RMU load switch requires a higher performance and smaller size, the new load switch came into being, which in turn led to the technological advances RMU, RMU today not only excellent performance but also a series it also extends the range of use RMU.
