Power photoelectric signal generator

Abstract

The invention provides a power photoelectric signal generator, belonging to a discharge simulating test device used for diagnosing insulating property of electrical equipment in a power department. The power photoelectric signal generator comprises a local discharge sampling processor containing a photoelectric sampling pipe, wherein the photoelectric sampling pipe is arranged on the upper surface of a box body of the local discharge sampling processor; 220V electric supply is introduced to two input terminals of an autotransformer B, one output terminal of the autotransformer B is sequentially connected with a capacitor C and a control switch K in series and then is connected with an upper electrode sphere, the other output terminal of the autotransformer B is connected with a lower electrode sphere, the upper electrode sphere is fixed on the lower part of an upper pressure plate, the lower electrode sphere is fixed on the upper part of a lower pressure plate, and a discharge gap is reserved between the upper electrode sphere and the lower electrode sphere; and the photoelectric sampling pipe is arranged in the collection range of discharge spark of the upper electrode sphere and the lower electrode sphere. The power photoelectric signal generator disclosed by the invention is smart and light, easy to operate and safe and reliable.

Description

technical field [0001] The invention relates to a discharge test device, in particular to a simulated discharge test device for diagnosing the insulation status of electrical equipment in the electric power sector. Background technique [0002] Due to long-term operation and load impact of high-voltage electrical equipment, bubble gaps and high-temperature impurities will appear in the insulating layer, and partial discharge may occur under the action of a strong electric field. The charged protons of the discharge will hit the metal surface, form charge transfer, and produce luminescence. At the same time, it will also cause heat, sound, ozone, etc., which will further corrode the insulating material and form a vicious circle. The power system poses a serious safety hazard. [0003] The main object of partial discharge device monitoring is photoelectric and spectrum signals. Photoelectric detectors and high-frequency detection heads are used to convert optical radiation si...

Problems solved by technology

After the replacement, it is not so easy to return to the site for testing, because you have to re-apply, re-contact, wait for rescheduling, etc., which is very passive and inconvenient

[0007] The advantage of this on-site test method is that it conforms to the operating conditions, is close to the actual measurement effect, and can choose the best position for detector placement, etc.; the disadvantage is that the action is large, the ostentation is large, the danger is great, and a boost is often completed within a few minutes. , so if the detector is installed incorrectly or the device is damaged, etc., it is difficult to judge and troubleshoot the fault in an emergency state, resulting in the failure of the test
