Because there are characteristics such as dispersiveness, uncontrollability in the on-the-spot corona discharge phenomenon of electric system, if carry out on-the-spot ultraviolet training, can expend great amount of manpower and material resources, financial resources, and also result of training is general.
The utility model content
Advantages such as the utility model is for solving the problems of the technologies described above, and provides a kind of analog electrical corona ultraviolet to detect test unit, and it has conveniently, directly perceived, accurate.
To achieve these goals, the utility model adopts following technical scheme.
A kind of analog electrical corona ultraviolet detects test unit, comprises control desk, ultraviolet voltage generator, ultraviolet fault simulation test unit, ultraviolet imagery instrument; Described ultraviolet voltage generator is fixed on the control desk, and the ultraviolet voltage generator is connected with ultraviolet fault simulation test unit, is provided with a trouble spot at least on the described ultraviolet fault simulation test unit, and described ultraviolet imagery instrument is aimed at the trouble spot.
As further improvement of the utility model, described ultraviolet fault simulation test unit is the 110kV insulator chain.
Described trouble spot can be four.
The utility model is a kind of test unit that can simulate generation corona discharge phenomenon, effectively realize the corona discharge phenomenon that electrical equipment causes because of insulation defect reasons such as loose contact, crackle, pollution flashover, the disconnected thighs of lead in the real training chamber, and utilize Ultraviolet Detector to carry out ultraviolet and detect training, for the training of electrical equipment repair based on condition of component provides powerful technical support, filled up domestic repair based on condition of component training in the blank in this field.
The beneficial effects of the utility model: just can effectively realize the corona discharge phenomenon that electrical equipment causes because of insulation defect reasons such as loose contact, crackle, pollution flashover, the disconnected thighs of lead in the real training chamber.Make the training of ultraviolet detection technique not be subjected to the restriction in time, place, what be conducive to train carries out comprehensively.In addition, ultraviolet detector can intuitively show operational outfit discharge position, discharge form.Antijamming capability is strong, and the discharge accurate positioning is highly sensitive, and the advantages such as influence that are not subjected to sunshine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1, control desk; 2, ultraviolet voltage generator; 3,110kV insulator chain; 4, ultraviolet imagery instrument.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, this device mainly is made up of control desk 1, ultraviolet voltage generator 2,110kV insulator chain 3 three parts.By regulating the control device on the control desk 1, make the certain high voltage of ultraviolet voltage generator 2 outputs, action of high voltage is on 110kV insulator chain 3, be provided with four trouble spots on the 110kV insulator chain 3, be respectively: loose contact, insulator surface have disconnected strand of crackle, insulator surface lead dirty, that connect insulator.
The insulator that breaks down will produce the corona discharge phenomenon under high-tension effect.The student can use ultraviolet imagery instrument 4 to observe the corona discharge phenomenon, finds out the trouble spot.
Though above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
