Description
Technical field
The utility model relates to the discharge test device, is the simulation discharge test device that power department is used to diagnose the insulation of electrical installation situation specifically.
Background technology
High voltage electric equipment is because of long-time running, and load impact etc. can make insulation course bubble gap, high temperature impurity etc. occur, under the highfield effect, shelf depreciation possibly take place.The charged protons of discharge can be clashed into the metal surface, forms electric charge and shifts, and produces luminescence phenomenon; Also can cause heat, sound, ozone etc. simultaneously, insulating material is further corroded, form vicious cycle; Finally make insulating material major injury and even puncture, cause serious potential safety hazard to electric system.
The shelf depreciation device monitoring mainly to as if photoelectricity and spectrum signal; Utilize photodetector and high frequency detecting head to convert optical radiation signal into electric signal; The power that reflects shelf depreciation through analyzing and processing to electric signal; Thereby detect the seriousness of failure judgement, send communication to production management system.
Whether in proper working order for detecting the shelf depreciation device, should adopt the shelf depreciation analogue means.
Existing shelf depreciation analogue means is as shown in Figure 1, on high-voltage boards such as 35Kv, 110Kv 1, places two metalworks as sparking electrode 2 (as fastening at the disconnecting link exposed part); Select the optimum position of detector 3 acquired signal, give circuit disconnecting link etc. through the trial voltage that test cable 4 is regulated the tens thousand of volts that raise with buck control desk 6, the electrode 2 on bolt ties up to will discharge, and sends electric spark.Because this is to do the test of impacting with high pressure property, have quite danger, thus must install fence 5,7 additional on every side and special messenger's monitoring etc. is set, very serious nervous.
In site test, the master worker of cooperation adds voltage very highly such as us, and strength of discharge is very big, and the naked eyes visible light width of cloth reach more than one centimetre.Detectable device is not reaction unexpectedly, and pressure build-up test situation twice or thrice is identical, obviously is that detector is out of joint, is out of order but analyze several times to regulate all not mediate, and haves no alternative but, and have to withdraw the scene.Get back to self unit, it is that the photoelectricity sampling pipe has been broken that final inspection goes out.After the replacing, do experiment in the scene that return to, just so uneasy, because application again again, contact is again waited for and being rearranged etc., and is very passive and inconvenient.
The advantage of this site test mode is to meet operating condition, near measured result, can select the optimum position of detector storing etc.; Shortcoming is that action is big, and grand style is big, and is dangerous big, and once boosts and often in a few minutes, accomplish, so if occur detector install not to or device failure phenomenon etc., under the emergency circumstance, be difficult to judgement and mediate fault, cause test failure.
The utility model content
The purpose of the utility model provides a kind of easy to operate, safe and reliable electric power photo-generator.
This novel purpose is achieved in that a kind of electric power photo-generator, comprises the shelf depreciation sampling processor that contains the photoelectricity sampling pipe, and said photoelectricity sampling pipe is installed in the casing upper surface of shelf depreciation sampling processor; Two input ends of autotransformer B are introduced the 220V civil power; After being connected in series capacitor C, CS K in order, the output terminal of autotransformer B is connected to the upper electrode ball; Another output terminal of autotransformer B is connected to the lower electrode ball; The upper electrode ball is fixed on position under the top board, and the lower electrode ball is fixed on the lower platen upper part, and between upper electrode ball and the lower electrode ball discharging gap is arranged; Above-mentioned photoelectricity sampling pipe is positioned at the acquisition range of upper and lower part ball electrode discharge spark.
Above-mentioned capacitor C is 0.33 μ f, withstand voltage metal film electric capacity greater than 400V.
Discharging gap between above-mentioned upper electrode ball and the lower electrode ball is not more than 1mm.
This photo-generator adopts autotransformer that the energy both was provided, again to the control of discharge magnitude.When K switch was connected, the electric signal that comes from autotransformer sent the ball electrode that the gap arranges to through the withstand voltage coupling capacitance of height, produced the signal power, frequency has other electric spark; For shelf depreciation, spectral analysis and high-frequency test appearance provide information channel; Whether normal in order to detect judgment task, whether function realizes, to laboratory debugging and on-the-spot preliminary detection; Reduce tens thousand of volt high voltages the blindness of electrical equipment is applied, cause additional injuries etc.Ball discharge is designed to replaceablely in addition, has strengthened the dirigibility of structure, more the warranty test effect.
Under autotransformer up-down voltage-regulation; The photosignal that ball electrode discharges is not only strong and weak different; And the light wave pulse that produces also is not quite similar, and this will provide wideer more metrical information to being provided with the shelf depreciation device and the pertinent instruments of light belt spectrum analysis and high-frequency test function.
Compared with prior art, the beneficial effect of the utility model is:
1, this photo-generator small volume and less weight is carried easily, and handled easily not only can use in the laboratory, in working site and manufacturer's test, still has special role.Such as; Before the large-scale pressurization discharge of implementing like Fig. 1; Can use this instrument to connect the 220V power supply earlier, do the preparation property discharge test, after confirmation signal collection, electrooptical device etc. are in proper working order; Connect power frequency high voltage test instrument (or withstand voltage appearance) again, do real, up to the discharge test of tens thousand of volts.Like this, both can guarantee success ratio, and can reduce high voltage again and be added in the destroying infection in the transmission facility, so this photo-generator highly significant acts on.
2, safe and reliable.Can connect the 220V civil power generally speaking and simulate discharge test as the autotransformer input voltage, thus comparatively safe reliable.
This device can be used for diagnosing the insulation of electrical installation situation, discovery accident focus, and early prevention is handled, with support equipment and power grid security.
