The application should arouse and positioner, had overcome not enough that conventional overproof fault locating is complicated, the time cycle is long. Exert the environmental load who easily excites insulation resistance overproof through the stand alone device to the sensor, can improve the overproof fault locating of sensor insulation resistance greatly, showing the leadtime that improves the sensor.
Description
Technical field
This utility model relates to a kind of sensor detection equipment, particularly relates to a kind of equipment for sensor fast and accurately carries out insulation resistance localization of fault, flaw detection.
Background technology
Insulation resistance is the very important technical performance of aero-engine sensor, and whether qualified insulation resistance is directly determines that can sensor function normally realize. But because the factor affecting insulation resistance performance is various, the overproof fault that insulate is difficult to position, and the fault location cycle is long, causes very big difficulty to airborne sensor development and production.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of overproof fault of sensor insulation resistance quickly to excite and positioner, solves quickly exciting and orientation problem of the overproof fault of sensor insulation resistance.
The purpose of this utility model, to be achieved by the following technical programs: a kind of overproof fault of sensor insulation resistance quickly excites and positioner, it is characterized in that described device has a seal case, it is provided with in described seal case and each independent add warm spot, pressure point and add wet point, and seal case side offers uncovered; Described device is provided with the mounting seat of more than one specifications that corresponding insulation resistance multistage form fit to be measured is planted, and mounting seat is replaceable is secured to uncovered middle sealing.
Further, the junction of described mounting seat and insulation resistance to be measured is filled out and is provided with silicone rubber seal.
Further, described seal case is the casing of Open-close sealing with cover, and described mounting seat is rigid block movement, described mounting seat be spirally connected seal be assemblied in seal case uncovered in.
Remarkable result after technical solutions of the utility model application implementation is: this device overcomes the deficiency of conventional overproof fault location complexity, time cycle length. By self-contained unit, sensor is applied the environmental load being prone to excite insulation resistance overproof, it is possible to be greatly improved the fault location that sensor insulation resistance is overproof, significantly improve the lead time of sensor.

Detailed description of the invention
Hereinafter just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are more readily understood, grasp.
Being drawn by theory analysis, the topmost influence factor of insulation resistance is damp and hot and temperature. When ambient humidity is bigger, dielectric adsorbing moisture, form moisture film or water crystallization, cause insulation resistance to significantly reduce; After ambient temperature raises, the polarization aggravation in dielectric, conductance increases, and causes insulation resistance to reduce.
This utility model is in view of the prior art deficiency to the overproof fault detect of insulation resistance, location aspect, principles above based on insulation resistance, for quickly exciting insulation resistance overproof, first sensor is heated, after sensor bulk temperature is stable, pressurize rapidly after cooling and improve ambient humidity, enabling the sensor insulator moisture absorption rapidly. Innovation proposes a kind of overproof fault of sensor insulation resistance and quickly excites and positioner.
As shown in Figure 1 to Figure 3, this overproof fault of sensor insulation resistance quickly excites and positioner has a seal case 4, and is provided with in this seal case 4 and each independent add warm spot 1, pressure point 2 and add wet point 3, and seal case 4 side offers uncovered 41. This device is provided with the mounting seat 6 of more than one specifications that corresponding insulation resistance to be measured 7 multistage form fit is planted simultaneously, and mounting seat 6 is replaceable is secured in uncovered 41 and seals.
Meanwhile, the junction of this mounting seat 6 visible and insulation resistance 7 to be measured is filled out and is provided with silicone rubber 5 enforcement sealing as shown in the figure. Reach the environment constant control in seal case.
For easy to operate, above-mentioned seal case 4 can be set to the casing of Open-close sealing with cover, and mounting seat is rigid block movement, be spirally connected mounting seat from-inner-to-outer seal be assemblied in seal case uncovered in. Can conscientiously improve the thorough sealing property in mounting seat assembling back sealed box body.
The embodiment of Fig. 1 to Fig. 3 is visible, for an insulation resistance, it is possible to implements segmentation detection according to its profile, excites and position overproof influence factor. It it is the insulation resistance first half section installment state that stretches into seal case shown in Fig. 1; It it is the installment state insulation resistance second half section stretching into seal case shown in Fig. 2; Mounting seat used under these two kinds of installment states in figure all mates corresponding insulation resistance stage casing external diameter. Being the installment state that seal case is goed deep in insulation resistance end, main body exposes shown in Fig. 3, mounting seat used under this kind of installment state then mates the external diameter of corresponding insulation resistance end. But no matter adopt which kind of mounting seat, must fill out after insulation resistance with mounting seat assembling and set silicone rubber enforcement sealing.
In specific implementation process, said apparatus can operate as follows:
A), according to the contour structures of sensor and size, choose suitable mounting seat, by after mounting seat and sensor matching, by realizing sealing at junction coating silicon rubber, then mounting seat is installed on seal case.
B), by firing equipment to being heated (heating-up temperature is determined according to the actual maximum temperature born of sensor) in seal case, after heating 1 hour, it is possible to make sensor insulation resistance recover normal.
C), then by humidifying and seal case is humidified and pressurizes by pressurized equipment, humidity is not less than 95%, and pressure is not less than 57kPa, cancels heating, is maintained at high pressure and high humidity environment certain time.
D), seal case is recovered standard atmosphere condition, take out sensor, after the moisture volatilization of sensor surface attachment, carry out insulation resistance detection, if insulation resistance is overproof, trouble point completes location, as fruit product insulation resistance is good, then the mounting means of sequential transformations insulation resistance to be measured, repeats above step and carries out fault location.
To sum up the detailed description for this device and detection process thereof is visible, compares to conventional detection devices, which overcomes the deficiency of conventional overproof fault location complexity, time cycle length. By self-contained unit, sensor is applied the environmental load being prone to excite insulation resistance overproof, it is possible to be greatly improved the fault location that sensor insulation resistance is overproof, significantly improve the lead time of sensor.
In addition to the implementation, this utility model can also have other embodiment. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within this utility model scope required for protection.
