Description
Technical field
The utility model relates to Intelligent switch cabinet monitoring system field, specifically a kind of partial discharge of switchgear intelligent online monitoring system.
Background technology
High-tension switch cabinet is one of very important electrical equipment in electric system.Along with the enforcement of country " 12 " planning and the development of national economy, society has higher requirement to power supply reliability.State Council is in the < < National Program for Medium-to Long-term Scientific and Technological Development > > of in February, 2006 issue, and ultra-large power transmission and distribution and power grid security guarantee are listed in the preferential theme in these major fields of the energy.
High-tension switch cabinet is as a kind of power equipment of extensive utilization, and its safe reliability also thereby be subject to paying close attention to widely.According to incompletely statistics, all there is high voltage switch cabinet fault in various degree in domestic many gencos, Utilities Electric Co., and cause sizable economic loss.These faults, some is from the quality problems of switch cubicle itself, and prior reason is to lack the effective monitoring means for switch cubicle, as avoids a switch cubicle accident and retrieve direct or indirect economic loss all at Renminbi more than 1,000,000 yuan.
Switch cubicle failure reason analysis is as follows:
(1), the running environment of high-tension switch cabinet is poor, is often subject to the invasion and attack such as dust, smog, steam etc., and surface of insulating layer is corroded, and generates conducting objects, form insulation defect, thereby cause fault.
(2), the loose contact of high-tension switch cabinet inside contact, that the eccentric undesired reason of pegging graft causes is overheated, so that causes bad equipment of arcing.
(3), switch cubicle a large amount of arclight failure accident of being in operation and occurring, be mostly the impact due to environmental baseline, insulating material is made moist, apparatus insulated surface produces condensation and adheres to dirt, because apparatus insulated level declines, causes the accident.
Therefore, to the detection of switch cubicle electric discharge, synthetic fault diagnosis, early warning in early stage, and arclight monitoring, protection personnel and device security have very important significance.
The maximum application of switch cubicle on-Line Monitor Device both domestic and external is temperature survey, is mainly high-voltage switch gear to be refused to electrical contact temperature to measure with isolating, does not consider the status information such as load, environment parameter of switch cubicle.Therefore, these devices cannot be diagnosed the duty of electrical contact, can only make warning to abnormal temperature, and when there is abnormal temperature switch cubicle in or close to malfunction.
Present intelligent switchboard, is mainly confined to the action of monitoring switch cabinet, detects one or two temperature spots, does not possess the ability that switch cubicle is combined station information judgement.Its main deficiency is that to lack detection and the temperature detection position of switch cubicle electric discharge very few, does not detect the situation that every phase contact temperature changes.
High-tension switch cabinet is just towards transformation and the intelligent development of existing equipment; Intelligent High-voltage Switch Cabinet has protection, control and monitoring and fault diagnosis; and numeral shows, high-voltage switch gear state shows, external functions such as bidirectional data communication; realize its inner and with host computer between communicate by letter, meet to greatest extent the requirement of information sharing and the system integration.
