Description
Technical field
The invention belongs to spacecraft process measurement frock, it particularly relates to solar array drives on a kind of spacecraft
The insulation measurement frock of dynamic device (SADA, solar array drive assembly) support.
Background technology
For realizing the floating ground requirement of SADA, it is to avoid SADA with SADA bracket mounting face contacts conducting, uses at SADA support
Upper stickup polyimide insulative film, thus realize the isolation between SADA and support.Generally, the polyamides of material selection 100m is made
Imines film, the dielectric film of cutting can not have crackle and breach.Generally, the structure of SADA support polyimide (PI) film such as Fig. 1 institute
Showing, wherein, the polyimide film on SADA support circumference has 11 holes, and wherein on lower half circumference, 7 holes set every 30 degree
Putting, on upper semicircumference, 4 holes are symmetrical arranged, and two holes of lower section become 30 respectively with two holes of horizontal diameter circumferential position
Degree, two holes of top become 20 degree respectively with perpendicular diameter circumferential position.
During spacecraft, the insulation resistance value between SADA support polyimide (PI) film and SADA support need to be entered
Row is measured, it is desirable to the measurement point resistance of more than 20 is not less than 1M, typically takes the original-pack standard type made with common circuit tester
Number test pencil measures, but, former measuring method is in following drawback:
1) due to SADA install be face contact, use reconnaissance measure method whole installed surface cannot be checked, deposit
Feature in spreadability difference, it is impossible to ensure the installation quality of SADA dielectric film, owing to SADA floating ground resistance has strict demand, if
This insulation effect is unsatisfactory for requirement, can directly result in floating ground resistance when follow-up SADA installs and be unsatisfactory for requirement, cause SADA repeatedly
The risk of dismounting；
2) using pen meter of universal meter directly to contact dielectric film when measuring to measure, metal test pencil is in more than 20 secondary repeated measurements
Dielectric film is easily caused damage by journey, thus increases the risk of follow-up SADA installment work；
3) measure between pen meter of universal meter and tactile dielectric film and there is active force, test pencil during measuring in measurement angle
Control can not be quantized with measurement dynamics, be likely to result in dielectric film and produce relative displacement with SADA support, cause dielectric film anti-
The risk of multiple dismounting；
4) reviewer need to carry out the measurements of more than 20 times to dielectric film, during the measurement working expenditure of repeatability while also increase
The risk of operation.
Summary of the invention
For the deficiency of measuring method in prior art, develop one and measure resistance detection between SADA support and dielectric film
Frock, solves all standing inspection of SADA support polyimide (PI) film 100%.
The technical solution used in the present invention is as follows:
Polyimide film insulation inspection tool on spacecraft solar array driving means support, including poly-for being pressed together on
Measurement annulus, electricity rubber ring, handle, positioner and test pencil seat, the polyimides on described support circumference on acid imide film
Film has 11 holes, and wherein on lower half circumference, 7 holes are every 30 degree of settings, and on upper semicircumference, 4 holes are symmetrical arranged, under
Two holes of side become 30 degree respectively with two holes of horizontal diameter circumferential position, two holes of top and perpendicular diameter circumferential position
Become 20 degree respectively；Wherein, electricity rubber ring is pasted onto the side measuring annulus pressing polyimide film, measures annulus opposite side and arranges
Have by three core handles formed joined integrally grabbing bar, three grab bar be mechanically fixed respectively be connected to measure annulus
On, three fixed positions grabbing one of bar are corresponding to perpendicular diameter circumferential position on the upper semicircumference of described film, and another two is symmetrical
The fixed position grabbing bar corresponds respectively to become the position of 20 degree, any bit of lower half circumference with the diametrical position of lower half circumferential level
Put the test pencil seat being provided with for plugging one of digital multimeter leucorrhea test pencil.
Further, positioner is to measure the limited post that annulus is prominent on pressing polyimide film side；
Further, grab bar and be fixedly attached to measure on annulus by screw for three.
Further, it is provided with interior spacing auricle between screw and measurement annulus.
Wherein, measure annulus and handle is made by aluminium alloy；
Wherein, electricity rubber ring includes that conductive tape and the 2mm thickness rubber blanket being coated with it are made.
Wherein, test pencil seat is connected by screw connection manner with measuring annulus and turns on, as this frock and pen meter of universal meter it
The interface of one.
Wherein, another test pencil of circuit tester is connected with the shell ground, cabin of spacecraft.
The present invention compared with prior art, has the advantage that
Judged with using conventional numerical circuit tester leucorrhea test pencil to measure resistance on dielectric film in the past, and utilized test pencil absolutely
The inspection method measuring some measurement insulation resistance value choosing more than 20 on velum is compared, after using this frock, for spacecraft
Quality safety serve guaranteeing role.The work of dielectric film resistance becomes simple to operation to make reviewer check, and stable
Reliably, not only increasing detection efficiency, also stopped original measuring method and there is drawback, advantage is as follows:
1) insulate test mode by SADA support polyimide (PI) film, is improved to the face way of contact from point cantact mode, can
Whole installed surface is checked, it is achieved SADA support polyimide (PI) film 100% all standing, stopped former method and cannot protect
The installation quality of card SADA dielectric film, it is to avoid when follow-up SADA installs, floating ground resistance is unsatisfactory for requirement, causes SADA repeated disassembled and assembled
Risk；
2) the measuring surface adhesive material measuring frock is well conducting and flexible material, has stopped former method rigid metal table
Dielectric film is caused the possibility of damage by pen in more than 20 secondary repeated measurement processes；
3) measure frock to touch dielectric film when measuring be in parallel relation with SADA, and measure the direct perpendicular acting of frock
Touch dielectric film in SADA, thus avoid the possibility of dielectric film and the generation relative displacement of SADA support, reduce dielectric film repeatedly
The risk of dismounting；
4) measure frock can disposable all standing SADA dielectric film is checked, reviewer is without entering dielectric film
The measurement that row is more than 20 times, when reducing measurement working expenditure, improves the inspection efficiency of SADA dielectric film.
