【摘要】：隨著社會的發(fā)展,人們對生活的需求逐步提高,對供電可靠性的要求亦逐步提升,提升供電可靠性,減少用戶停電時間、停電次數(shù),降低線路及設(shè)備跳閘率已成為電網(wǎng)企業(yè)新的主題。電網(wǎng)設(shè)備檢修目前推行狀態(tài)檢修,但是狀態(tài)檢修獲取設(shè)備狀態(tài)量仍需對設(shè)備進行停電,不符合當前社會對電網(wǎng)企業(yè)的新要求,因此,不停電檢測技術(shù)獲取設(shè)備狀態(tài)量的研究就迫在眉睫。變電站內(nèi)直接對用戶供電產(chǎn)生影響的是各用戶出線間隔的設(shè)備檢修,這些出線間隔設(shè)備目前基本為開關(guān)柜設(shè)備,因此,推行不停電檢測技術(shù)的設(shè)備狀態(tài)檢修,首先應(yīng)完成開關(guān)柜設(shè)備的不停電檢測狀態(tài)檢修研究。本文研討了變電站開關(guān)柜設(shè)備的不停電檢測的狀態(tài)檢修技術(shù),制定了不停電檢測的開關(guān)柜狀態(tài)檢修的實現(xiàn)策略、實現(xiàn)方式,目前,開關(guān)柜不停電檢測的狀態(tài)檢修已在國家電網(wǎng)公司內(nèi)實施,有效的提升了開關(guān)柜設(shè)備檢修的效率。結(jié)合國內(nèi)不停電技術(shù)的發(fā)展現(xiàn)狀,本文分析了開關(guān)柜設(shè)備不停電技術(shù)的原理,根據(jù)不停電技術(shù)的應(yīng)用效果,分析了不停電檢測手段獲取設(shè)備狀態(tài)量的方式等,并結(jié)合安徽省宿州供電公司應(yīng)用實例,針對電網(wǎng)企業(yè)現(xiàn)行開關(guān)柜普遍運行條件,對不停電檢測開關(guān)柜狀態(tài)檢修技術(shù)進行了詳細介紹,對不同開關(guān)柜隱患、缺陷的分析、處理進行了全面對分析,進一步指導(dǎo)基于不停電檢測開關(guān)柜狀態(tài)檢修工作開展。實踐結(jié)果證明,本文所研究的開關(guān)柜不停電檢測的狀態(tài)檢修能有效的提高設(shè)備檢修效率,大大降低了用戶設(shè)備的停電次數(shù),同時還提升了開關(guān)柜設(shè)備的運維水平,降低了開關(guān)柜設(shè)備的故障率。
[Abstract]:With the development of society, people's demand for daily life has been gradually raised, and the demand for power supply reliability has also been raised step by step. The reliability of power supply has been improved, and the time and times of power outages have been reduced. Reducing line and equipment tripping rate has become a new topic for power grid enterprises. Power network equipment maintenance is being implemented at present, but the equipment condition quantity still needs to be cut off, which is not in line with the new requirements of the current society to the power grid enterprises, therefore, it is necessary to obtain the condition quantity of the equipment. It is urgent to obtain the equipment state quantity by non-blackout detection technology. The direct influence on the power supply to the users in the substation is the maintenance of the equipment between the lines of each user, which is basically the switchgear equipment at present. Therefore, the equipment condition maintenance of the non-blackout detection technology is carried out. First of all, should complete the switchgear equipment non-blackout detection condition maintenance research. This paper discusses the condition based maintenance technology of substation switchgear equipment without blackout detection, and formulates the realization strategy and realization mode of condition maintenance of switchgear without blackout detection. The condition maintenance of switchgear without outage detection has been implemented in State Grid Company, which effectively improves the efficiency of switchgear equipment maintenance. Combined with the development of non-blackout technology in China, this paper analyzes the principle of no-blackout technology for switchgear equipment, and analyzes the ways of obtaining the state quantity of equipment by means of non-blackout detection according to the application effect of no-blackout technology. Combined with the application example of Suzhou Power supply Company in Anhui Province, aiming at the prevailing operating conditions of switchgear in power grid enterprises, this paper introduces in detail the condition maintenance technology of non-blackout detection switchgear, and analyzes the hidden dangers and defects of different switchgear cabinets. The comprehensive analysis is carried out to further guide the condition maintenance of switchgear based on non-blackout detection. The practical results show that the condition based maintenance of the switchgear studied in this paper can effectively improve the efficiency of equipment maintenance, greatly reduce the number of outages of user equipment, and at the same time improve the level of operation and maintenance of switchgear equipment. The failure rate of switchgear is reduced.
