Description
Technical field
The utility model relates to a kind of supersonic sounding device, particularly a kind of inside transformer Solid Insulator Breakdown of Electric supersonic sounding device.
Background technology
Along with the development of electric power conveying technology, the operation maintenance of power equipment has become the important process ensureing electrical network reliability service.In the face of complicated power equipment, how in equipment runs, can understand its internal operation state at any time, be the groundwork that status of electric power is safeguarded.In the transformer run at the scene; often can there is the Solid Insulator Breakdown of Electric such as inner winding deformation and correcting wedge displacement; existing supersonic sounding device be transformer has been occurred electric discharge, overheating fault sound wave detect and analyze; when the solid structure generation subtle change of inside transformer; can not judge with accurate by Timeliness coverage; just can detect when only having subtle change to develop into comparatively serious fault, the best delaying equipment safeguards opportunity, causes great economic loss.
Summary of the invention
The utility model provides a kind of inside transformer Solid Insulator Breakdown of Electric supersonic sounding device, can not Timeliness coverage and the technical matters that accurately judges when solving the solid structure generation subtle change of inside transformer.
The utility model solves above technical matters by the following technical programs:
A kind of inside transformer Solid Insulator Breakdown of Electric supersonic sounding device, comprises transformer body and ultrasonic probe, is connected with wave form analysis processor, in ultrasonic probe, is provided with ultrasonic transmit circuit at ultrasonic probe.
The anode of the direct supply of ultrasonic transmit circuit is connected by current-limiting resistance one end with the electric capacity in oscillatory circuit, adjustable resistance links together with the other end mating the one end after inductance in parallel and electric capacity, adjustable resistance links together with the negative terminal mating the other end after inductance in parallel and direct supply, be parallel with ultrasonic generator at the two ends of coupling inductance, between the negative terminal and one end of electric capacity of direct supply, be connected with thyristor D.
The utility model structure is simple, realizes easily, to detect the generation of inside transformer Solid Insulator Breakdown of Electric timely and accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of ultrasonic transmit circuit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of inside transformer Solid Insulator Breakdown of Electric supersonic sounding device, comprises transformer body 1 and ultrasonic probe 3, ultrasonic probe 3 is connected with wave form analysis processor 4, be provided with ultrasonic transmit circuit 2 in ultrasonic probe 3.
The anode of the direct supply 5 of ultrasonic transmit circuit is connected with the one end of the electric capacity C in oscillatory circuit by current-limiting resistance R, adjustable resistance R
xwith mate inductance L parallel connection after one end and the other end of electric capacity C link together, adjustable resistance R
xwith mate inductance L parallel connection after the other end and the negative terminal of direct supply 5 link together, be parallel with ultrasonic generator 6 at the two ends of coupling inductance L, between the negative terminal and one end of electric capacity C of direct supply 5, be connected with thyristor D.
When current-limiting resistance R is less than 5f reciprocal (f is the frequency that ultrasonic probe 3 sends, and is generally 50 hertz), electric capacity C, before thyristor triggers, can be full of electricity, by regulating controllable tube D and adjustable resistance R
x, can control power and damping, the remained shock after signal launched by minimizing radiating circuit, is conducive to proximity detection and the process to echo, realizes the ultrasonic listening of inside transformer Solid Insulator Breakdown of Electric.
