Abstract
The invention discloses an electrical equipment overheating fault previewing apparatus which comprises a short time heavy current generator and an infrared thermal imager. The short time heavy current generator comprises a power supply, a pulse capacitor and a triggered vacuum switch, wherein, one end of the pulse capacitor is in series connection with one end of the triggered vacuum switch and then connects with the power supply, the other end of the pulse capacitor is in grounding, the other end of the triggered vacuum switch connects with electrical equipment to be checked and then is in grounding, and the infrared thermal imager is provided beside the electrical equipment. The electrical equipment overheating fault preview apparatus can conveniently and rapidly preview possibly existed defects of the electrical equipment to be put into operation, thus hidden trouble is eliminated before the electric power equipment is put into operation, production efficiency is substantially raised, the electrical equipment overheating fault preview apparatus has the characteristics of being simple, practical, convenient and fast, enforcement is easy, and security of power network operation is guaranteed.
Description
One, technical field: the present invention relates to a kind of device of overheating of electrical failure detector, particularly relate to a kind of electrical equipment overheating fault previewing apparatus.
Two. background technology: device of overheating of electrical is modal phenomenon in the distribution system, in decades, China power supply department adopts is that the operator on duty of transformer station makes an inspection tour range estimation electrical equipment major flow and partly whether generates heat, whether generate heat between later stage some areas or with the warm instrument measuring equipment of point, this traditional manual detection method labour intensity is large, high to the requirement of personnel's sense of responsibility, and detection efficiency is low, accuracy is low.Progress along with technology, to implement by the infrared thermal imaging detection technique again after a period of time at putting equipment in service to the detection of device of overheating of electrical fault at present, high and the robotization of efficient control, but, above-mentioned detection is all carried out in electric equipment operation, and the early stage heating hidden danger of electrical equipment major flow can't detect or occur erroneous judgement, and this affects the normal operation of equipment, cause the electric system paralysis when serious, lose huge.
Three. summary of the invention:
Technical matters to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, detect electrical equipment overheating fault previewing apparatus accurate, convenient and swift, easy enforcement.
Technical scheme of the present invention is: a kind of electrical equipment overheating fault previewing apparatus, contain in short-term strong current generator and infrared thermography, described in short-term strong current generator contains power supply, impulse capacitor and Triggered Vacuum Switch, wherein, one end of described impulse capacitor is connected with described power supply after the end serial connection of Triggered Vacuum Switch with being connected, the other end ground connection of described impulse capacitor, ground connection after the other end of described Triggered Vacuum Switch is connected with electrical equipment to be checked, described infrared thermography are arranged on described electrical equipment next door.
Described Triggered Vacuum Switch is provided with trigger controller.
The invention has the beneficial effects as follows:
1, the detection before the present invention can on-the-spotly put into operation to electrical equipment, effectively detect the hot defective of mistake of electrical equipment major flow, realize the in advance discovery, advanced processing of device of overheating of electrical defective, avoid equipment failure in advance, and then ensure the security of operation of power networks.
2, the present invention adopts the TVS Triggered Vacuum Switch, has that leakage current large (can reach more than the 100kA), withstand voltage height, controllability are good, high reliability.
3, easily and quickly preliminary examination of the present invention equipment the to be put into operation defective that may exist, thus before really putting into operation, equipment removes a hidden danger, greatly to enhance productivity, its simple and practical, convenient and swift, easy enforcement has good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 is the structural representation of electrical equipment overheating fault previewing apparatus.
Five. embodiment:
Embodiment: among the figure, 1-power supply, 2-Triggered Vacuum Switch (TVS), 3-trigger controller, 4-infrared thermography, 5-electrical equipment, 6-impulse capacitor.
Electrical equipment overheating fault previewing apparatus contains in short-term strong current generator and infrared thermography 4, strong current generator contains power supply 1, impulse capacitor 6 and Triggered Vacuum Switch (TVS) 2 in short-term, wherein, one end of impulse capacitor 6 is connected TVS with Triggered Vacuum Switch) be connected with power supply 1 after 2 the end serial connection, the other end ground connection of impulse capacitor 6, ground connection after the other end of Triggered Vacuum Switch (TVS) 2 is connected with electrical equipment 5 to be checked, infrared thermography 4 is arranged on electrical equipment 5 next doors.Triggered Vacuum Switch (TVS) 2 is provided with trigger controller 3.
Before electrical equipment 5 puts into operation, plugged 1, make two central electrode fast conductings of Triggered Vacuum Switch (TVS) 2 by trigger controller 3, the electric current of output 2000A-5000A is applied on the electrical equipment to be measured 5 within 5 seconds, 10 seconds, 15 seconds time period, infrared thermography 4 is surveyed the temperature variation of electrical equipment 5, and export the progressive image of 30 frames/seconds 320 * 240 dot matrix, according to image, judge whether electrical equipment 5 exists the overheating defect situations such as loose contact.
