Description
Technical field
The invention belongs to spacecraft process measurement frock, specifically, relate to the insulation measurement frock that solar array drive unit on a kind of spacecraft (SADA, solar array drive assembly) support is used.
Background technology
For realizing the floating ground requirement of SADA, avoid SADA to contact conducting with SADA support installed surface, adopt and on SADA support, paste polyimide insulative film, thereby realize the isolation between SADA and support.Conventionally, make the polyimide film of material selection 100m, the dielectric film of cutting can not have crackle and breach.Conventionally, the structure of SADA support polyimide (PI) film as shown in Figure 1, wherein, polyimide film on SADA support circumference has 11 holes, and wherein, on second circumference, 7 holes are every 30 degree settings, on upper semicircumference, 4 holes are symmetrical arranged, and two holes of below become respectively 30 degree with two holes of horizontal diameter circumferential position, and two holes of top become respectively 20 degree with perpendicular diameter circumferential position.
In spacecraft process, need measure the insulation resistance value between SADA support polyimide (PI) film and SADA support, require 20 above measurement point resistances to be not less than 1M, generally take the original-pack standard model test pencil making with common multimeter to measure, but former measuring method is in following drawback:
1) because SADA installs, be face contact, the method that adopts reconnaissance to measure cannot check whole installed surface, there is the poor feature of spreadability, cannot guarantee the installation quality of SADA dielectric film, because floating ground of SADA resistance has strict demand, if this insulation effect does not meet the demands, in the time of can directly causing follow-up SADA to install, floating ground resistance is discontented with sufficient requirement, causes the risk of SADA repeated disassembled and assembled;
2) while measuring, adopt pen meter of universal meter directly to contact dielectric film and measure, in the repeated measurement process of metal test pencil more than 20 time, easily dielectric film is caused to damage, thereby increase the risk of follow-up SADA installment work;
3) measure between pen meter of universal meter and tactile dielectric film and have acting force, test pencil in measuring process in take measurement of an angle and can not be quantized control with measurement dynamics, may cause dielectric film and SADA support to produce relative displacement, cause the risk of dielectric film repeated disassembled and assembled;
4) reviewer need carry out to dielectric film the measurement of more than 20 times, and repeated surveying work has also increased the risk of operation in the time of time-consuming.
Summary of the invention
For the deficiency of measuring method in prior art, develop one and measure resistance detection frock between SADA support and dielectric film, all standing inspection that has solved SADA support polyimide (PI) film 100%.
The technical solution used in the present invention is as follows:
Polyimide film insulation on spacecraft solar array drive unit support checks frock, comprise for being pressed together on the measurement annulus on polyimide film, electric rubber ring, handle, locating device and test pencil seat, polyimide film on described support circumference has 11 holes, wherein on second circumference, 7 holes are every 30 degree settings, on upper semicircumference, 4 holes are symmetrical arranged, two holes of below become respectively 30 degree with two holes of horizontal diameter circumferential position, and two holes of top become respectively 20 degree with perpendicular diameter circumferential position; Wherein, electricity rubber ring sticks on a side of measuring annulus pressing polyimide film, measuring annulus opposite side is provided with by three core one of grabbing bar in conjunction with the handle forming, three grab bar respectively machinery be fixedly connected on and measure on annulus, three fixed positions of grabbing one of bar are corresponding to perpendicular diameter circumferential position on the upper semicircumference of described film, the fixed position that another two symmetries are grabbed bar corresponds respectively to the position that becomes 20 degree with the diametrical position of second circumference level, is provided with for the test pencil seat that plugs one of digital multimeter leukorrhea test pencil on arbitrary position of second circumference.
Further, locating device is for measuring annulus for outstanding limited post in pressing polyimide film one side;
Further, grab bar and be fixedly attached to and measure on annulus by screw for three.
Further, between screw and measurement annulus, be provided with interior spacing auricle.
Wherein, measuring annulus and handle makes by aluminium alloy;
Wherein, electric rubber ring comprises that conductive tape and coated its thick rubber blanket of 2mm make.
Wherein, test pencil seat is connected and conducting by the mode of being spirally connected with measurement annulus, the interface as this frock with one of pen meter of universal meter.
Wherein, the shell ground, cabin of another test pencil of multimeter and spacecraft is connected.
The present invention compared with prior art, has the following advantages:
With adopted conventional digital multimeter leukorrhea test pencil on dielectric film, to measure resistance to judge in the past, the inspection method of utilizing test pencil to choose more than 20 measurement point measurement insulation resistance values on dielectric film is compared, after using this frock, for the quality safety of spacecraft has played guaranteeing role.Make reviewer check that the work of dielectric film resistance becomes simple to operation, and reliable and stable, not only improved detection efficiency, also to stop original measuring method and had drawback, advantage is as follows:
1) by SADA support polyimide (PI) film insulation test mode, from a way of contact, be improved to the face way of contact, can check whole installed surface, realize 100% all standing of SADA support polyimide (PI) film, stopped the installation quality that former method cannot guarantee SADA dielectric film, while avoiding follow-up SADA to install, floating ground resistance is discontented with sufficient requirement, causes the risk of SADA repeated disassembled and assembled;
2) the measurement face adhesive material of measurement frock, for conduction is good and flexible material, has been stopped former method rigid metal test pencil and dielectric film has been caused to the possibility of damage in more than 20 inferior repeated measurement processes;
3) measure frock and touch dielectric film in parallel relation with SADA when measuring, and measure frock and directly vertically act on SADA and touch dielectric film, thereby avoided the possibility of dielectric film and SADA support generation relative displacement, reduced the risk of dielectric film repeated disassembled and assembled;
4) measure frock can disposable all standing SADA dielectric film is checked, reviewer, without the measurements of dielectric film being carried out to more than 20 times, reduces surveying work time-consuming, improves the checking efficiency of SADA dielectric film.
