In recent years, along with the continuous expansion of electrical network scale, transmission voltage grade also improves constantly, and damage, the fault of the various types of high-tension apparatuses used in electric system also constantly increase, and the frequency that insulation fault occurs also improves constantly.Substation Electric Equipment works under physical environment, in some cases, along with the reduction of insulating property, the appearance of fault of construction, can produce electric discharge and local, surface pollution flashover electric discharge phenomena.Arcing electric discharge and pollution flashover detection are carried out to electrical equipment, the deterioration condition insulating and may occur can be grasped on the one hand in time, before major accident occurs, just can determine the unsafe condition insulated, thus avoid the generation of accident; On the other hand, realization that is intelligent for fault diagnosis and Electrical Equipment Maintenance Based on State has great importance.
At present, the arcing electric discharge of substation equipment and pollution flashover detection method are mainly and utilize infrared thermography method and ultraviolet imager method to carry out off-line monitoring.
Infrared thermography method is a kind of wavelength conversion technology, namely infrared radiation images is converted to the technology of visual image, it utilizes in measurement target the feature having larger thermograde or background and target to have larger hot contrast, and low visual object is easily seen in infrared imaging.Because the target of electric discharge is little, intensity is weak, simultaneously in sunshine containing very strong infrared ray, be affected by the external environment large, it is slow that infrared thermal imaging technique has response speed, the fatal weakness such as accuracy is low.When monitoring arcing electric discharge and pollution flashover electric discharge with infrared thermoviewer, electrical equipment electric discharge is very serious.
Utility model content
The purpose of this utility model is to solve current substation equipment arcing electric discharge and pollution flashover on-line monitoring employing infrared thermography method, there is the defect of response speed slowly, at the bottom of accuracy, the full-time blind substation equipment arcing electric discharge of a kind of scan-type and pollution flashover On-line Discharge monitoring device are provided, it adopts ultraviolet imager method, there is fast response time, when equipment under test and ultraviolet imagery detector make versus high motion, still can complete high-quality detection, compared with the infrared thermal imaging technique generally adopted at present, can the early stage hidden danger of discovering device.
The utility model is achieved by the following technical solution:
The i.e. full-time blind substation equipment arcing electric discharge of a kind of scan-type and pollution flashover On-line Discharge monitoring device, it is characterized in that comprising image acquisition front end, picture signal transmission link and supervisory control comuter, described image acquisition front end comprises ultraviolet imager and electric platform, ultraviolet imager is at least 1, the bottom of ultraviolet imager is arranged on electric platform, and ultraviolet imager, electric platform are connected with supervisory control comuter by picture signal transmission link.
Picture signal transmission link is wireless and/or wire signal transmission link.
Wire signal transmission link is optical cable.
Ultraviolet imager of the present utility model adopts the optical filtering technique of full-time blind type, can disturb, can work by day from sunshine.
Electric platform of the present utility model leaps the FY-SP50E type intelligent speed changing The Cloud Terrace that Electromechanical Technology Co., Ltd produces for Jinan.
The image acquisition front end that the utility model is made up of the ultraviolet imager being mounted on comprehensive electric platform one or several, the picture signal transmission link formed based on wireless or wired or optical cable, run on the formation such as Monitoring and Controlling program or expert diagnosis software on background monitoring computing machine.
Image acquisition front end of the present utility model is made up of or several ultraviolet imagers installing, be fixed on comprehensive electric platform.Two of electric platform perform electronic acceptance and accurately run location from the control signal of the watchdog routine on background computer, drive ultraviolet imager on The Cloud Terrace up and down or left rotation and right rotation, ultraviolet imager on The Cloud Terrace achieves and automatically carries out scanning monitoring on a large scale to transformer station, autoscan monitors porcelain insulator or the equipment corona discharge situation of the setting regions of transformer station, also can realize under the manipulation of supervisory control of substation center operator on duty, trace and monitor object arcing electric discharge and pollution flashover situation.
The picture signal of image acquisition front-end collection of the present utility model transfers to background monitoring computing machine via wired, wireless or optical cable media.
Special monitoring software on supervisory control comuter of the present utility model shows the picture signal of front end ultraviolet imager collection automatically, analytical calculation, the corona discharge situation of monitoring key equipment, and capable of automatic alarm.Also analyze by the picture signal of manual type to front end ultraviolet imager collection, to monitor the corona discharge situation of key equipment.
Ultraviolet imager method is exactly the ultraviolet signal utilizing ultraviolet imager to receive electric discharge generation, and imaging after treatment superposes with visible images, reaches the object determining discharge position and intensity.Ultraviolet imager method can be accomplished not have a power failure, do not change the running status of system, thus equipment time of day information under operation detected.Can in the form of images, rapid, vivid, to demonstrate equipment intuitively running status and failure condition.
The fast response time that ultraviolet image method detects, when equipment under test and ultraviolet imagery detector make versus high motion, still can complete high-quality detection.Compared with the technology such as the infrared thermal imaging generally adopted at present, ultraviolet imagery technology can the early stage hidden danger of discovering device, and infrared thermal imaging technique often etc. hidden danger develop into and to a certain degree just can detect.
The utility model has the advantage that automaticity is high, easy to use, fast response time, detection efficiency are high.Ultraviolet imager method is applied in the on-line monitoring of substation equipment by the utility model, achieve the round-the-clock automatic monitoring of substation equipment, can detection efficiency be substantially increased, and reduce labour intensity, and can the initial failure of Timeliness coverage equipment, avoid the generation of industrial accident.
