Abstract
The utility model discloses an overheat defect detection device for electric equipment to be commissioned in a substation. The overheat defect detection device comprises a short-time large current generator and an infrared thermography; the short-time large current generator comprises a power supply, a pulse capacitor and a vacuum trigger switch, wherein one end of the pulse capacitor is connected with one end of the vacuum trigger switch in series and then is connected with the power supply; the other end of the pulse capacitor is grounded; the other end of the vacuum trigger switch is connected with electric equipment to be detected and then is grounded; and the infrared thermography is arranged beside the electric equipment. The overheat defect detection device for the electric equipment to be commissioned in the substation is capable of conveniently and rapidly detecting the possible defects of the electric equipment to be commissioned so as to eliminate the hidden dangers before the real commission of the electric equipment and greatly increase the production efficiency; and the overheat defect detection device has the advantages of simplicity, practicability, convenience, quickness and easiness in implementation and can be used for ensuring the running safety of grids.
Description
One, technical field: the utility model relates to a kind of device of overheating of electrical failure detector, particularly relates to a kind of transformer station wait to put into operation overheating defect pick-up unit of electrical equipment.
Two. background technology: device of overheating of electrical is a 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 appearance measuring equipment of point, this conventional artificial detection method labour intensity is big, high to the requirement of personnel's sense of responsibility, and detection efficiency is low, accuracy is low.Along with development of technology, the detection to the device of overheating of electrical fault is after equipment puts into operation a period of time, to implement through the infrared thermal imaging detection technique more at present, efficient height and robotization 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 influences the normal operation of equipment; Cause the electric system paralysis when serious, lose huge.
Three. the utility model content:
The utility model technical matters to be solved is: overcome the deficiency of prior art, provide a kind of reasonable in design, detect transformer station accurate, convenient and swift, easy enforcement wait the to put into operation overheating defect pick-up unit of electrical equipment.
The technical scheme of the utility model is: a kind of transformer station wait to put into operation overheating defect pick-up unit of electrical equipment; Contain strong current generator and infrared thermography in short-term; Said strong current generator in short-term contains power supply, impulse capacitor and vacuum trigger switch; Wherein, an end of said impulse capacitor is connected the other end ground connection of said impulse capacitor with an end of said vacuum trigger switch serial connection back with said power supply; The other end of said vacuum trigger switch is connected back ground connection with power equipment to be checked, said infrared thermography is arranged on said power equipment next door.
Said vacuum trigger switch is provided with the triggering controller.
The beneficial effect of the utility model is:
1, the detection before the utility model can on-the-spotly put into operation to electrical equipment; Detect the hot defective of mistake of electrical equipment major flow effectively; Realize the discovery in advance, advanced processing of device of overheating of electrical property defective, avoid equipment failure in advance, and then ensure the security of operation of power networks.
2, the utility model adopts TVS vacuum trigger switch, has leakage current big (can reach more than the 100kA), withstand voltage height, good, the reliability advantages of higher of controllability.
3, the utility model preliminary examination easily and quickly equipment to be put into operation defective that possibly exist; Thereby, equipment removes a hidden danger before really putting into operation; Enhance productivity greatly, its simple and practical, convenient and swift, easy enforcement has good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 is transformer station's wait to put into operation structural representation of overheating defect pick-up unit of electrical equipment.
Five. embodiment:
Embodiment: among the figure, the 1-power supply, 2-vacuum trigger switch (TVS), 3-triggers controller, 4-infrared thermography, 5-electrical equipment, 6-impulse capacitor.
Transformer station's wait to put into operation overheating defect pick-up unit of electrical equipment contains strong current generator and infrared thermography 4 in short-term; Strong current generator contains power supply 1, impulse capacitor 6 and vacuum trigger switch (TVS) 2 in short-term; Wherein, The one end serial connection back of one end of impulse capacitor 6 and vacuum trigger switch (TVS) 2 is connected with power supply 1; The other end ground connection of impulse capacitor 6, the other end of vacuum trigger switch (TVS) 2 are connected back ground connection with power equipment 5 to be checked, infrared thermography 4 is arranged on power equipment 5 next doors.Vacuum trigger switch (TVS) 2 is provided with and triggers controller 3.
Before electrical equipment 5 puts into operation; Energized 1, through triggering two quick conductings of central electrode that controller 3 makes vacuum trigger switch (TVS) 2, the electric current of output 2000A-5000A is applied on the electrical equipment to be measured 5 in 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 overheating defect situation such as loose contact.
Claims (2)
1. the transformer station overheating defect pick-up unit of electrical equipment of waiting to put into operation; Contain strong current generator and infrared thermography in short-term; It is characterized in that: said strong current generator in short-term contains power supply, impulse capacitor and vacuum trigger switch; Wherein, an end of said impulse capacitor is connected the other end ground connection of said impulse capacitor with an end of said vacuum trigger switch serial connection back with said power supply; The other end of said vacuum trigger switch is connected back ground connection with power equipment to be checked, said infrared thermography is arranged on said power equipment next door.
