Abstract
A kind of post insulator vibration acoustic pick-up unit with printing function, comprise the shell (2) of rectangular parallelepiped, be located at a pair taper detection contact (1) of cover top portion and the insulating bar (3) of bottom, be positioned at the acoustical signal launching and receiving shift knob (4) on insulating bar; The module group being positioned at enclosure interior be connected with detection contact is is sequentially connected and composed by acoustical signal launching and receiving module (5), data memory module (6), data processing module (7), intensity judge module (8), power module (12); Wherein intensity judge module (8) is connected with the normal pilot lamp of the intensity being positioned at outer casing bottom (9), the abnormal pilot lamp (10) of intensity and print module (11) respectively.The utility model can by testing result real time print out, more intuitively, intelligent, can significantly improve the accuracy of support insulator Site Detection and efficiency.
Description
Technical field
The utility model relates to post insulator vibration acoustic pick-up unit technical field, particularly a kind of post insulator vibration acoustic pick-up unit with printing function, and the post insulator vibration acoustic being applicable to each electric pressure detects.
Background technology
Support insulator in power equipment is as structural support, the impact be in operation due to environmental baseline and condition of work, constantly be subject to the effect of electric field, cyclic thermal stres, physical shock and environmental attack, its mechanical property can decline gradually with working time, occurs to lose efficacy to cause the risk of accident constantly to rise.It is the key ensureing its safe operation that support insulator has enough physical strengths.Only there is the environment sensitive of crack defect for support insulator privileged site in support insulator detection means conventional at present, belong to the detection method towards specified defect, the defect that support insulator may occur can not be characterized comprehensively, more can not characterize the physical strength of support insulator.
At present, the domestic method developed for support insulator intensity detection, and develop post insulator vibration acoustic pick-up unit.Utilize this device to detect the post insulator period of the day from 11 p.m. to 1 a.m, detection contact be against bottom insulator flange, the acoustic signal that contact sends is at interior insulator through reflection, and reflected signal passes to computing machine and carries out software analysis process.Technician, according to reflected signal characteristic, analyzes intensity and the inherent vice of support insulator.
But existing post insulator vibration acoustic pick-up unit detects the data obtained and is stored in equipment, can not show in time and consult, and at Computer display, can only delay testing staff and judge testing result in time.
Summary of the invention
The purpose of this utility model is just in order to overcome the defect that above-mentioned prior art exists, detecting for existing post insulator vibration acoustic can not visual display detecting result in time, can not the intuitive judgment contact whether problem such as good, provide a kind of can by the post insulator vibration acoustic pick-up unit of testing result real time print band printing function out.
The purpose of this utility model is achieved by the following technical solution.
With a post insulator vibration acoustic pick-up unit for printing function, comprise the shell of rectangular parallelepiped, be located at a pair taper detection contact of cover top portion and the insulating bar of bottom, be positioned at the acoustical signal launching and receiving shift knob on insulating bar; The module group being positioned at enclosure interior be connected with detection contact is is sequentially connected and composed by acoustical signal launching and receiving module, data memory module, data processing module, intensity judge module, power module; Wherein intensity judge module is connected with the normal pilot lamp of the intensity being positioned at outer casing bottom, the abnormal pilot lamp of intensity and print module respectively.
The testing result that the utility model can be printed by print module judges the concrete testing result of support insulator intuitively, and testing result can manifest in time consults.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As Fig. 1, a kind of post insulator vibration acoustic pick-up unit with printing function, comprise the shell 2 of rectangular parallelepiped, be located at a pair taper detection contact 1 at shell 2 top and the insulating bar 3 of bottom, be positioned at the acoustical signal launching and receiving shift knob 4 on insulating bar, with detection contact, the 1 module group being positioned at enclosure interior connected, described module group is is sequentially connected and composed by acoustical signal launching and receiving module 5, data memory module 6, data processing module 7, intensity judge module 8, power module 12; Wherein pilot lamp 9 normal with the intensity be positioned at bottom shell 2, the abnormal pilot lamp 10 of intensity and print module 11 are connected intensity judge module 8 respectively.
Concrete operation step of the present utility model is, is arranged on device housings 2 by insulating bar 3 by screw thread.According to support insulator height to be detected, select the insulating bar of appropriate length; Power-on, power module 12 is started working, and detection contact 1 is propped up post insulator metal flange, presses acoustical signal launching and receiving button 4, and acoustical signal launching and receiving module 5 is started working; Data return data processing module 7, and be stored in data memory module 6; Intensity judge module 8 is started working, and judge that whether testing result (insulator strength) is normal, if intensity is abnormal, pilot lamp 9 is lighted, if testing result is normal, the normal pilot lamp 8 of intensity is lighted; This detects end, and testing result prints by print module 11.
