Description
Technical field
The present invention relates to a kind of multi-joint self-lock switch, in particular to a kind of Solid Rocket Motor Ground Test it is multi-joint from
Lock-switch.
Background technique
Solid Rocket Motor Ground Test is a kind of priming system operation process, is carrying out field operation such as engine ignition
In device installation process, it is necessary to ensure that live ignition circuit short-circuit condition is carrying out ignition circuit inspection to ensure personal safety as well as the property safety
During survey, ensure ignition circuit normal ON, no short circuit phenomenon again, and guarantee working condition can accurate delivery to test
Supervisory control desk.
Currently, remaining in when carrying out hot work, artificial craft hot wire cable is simultaneously disconnected and test master control
The plug-in strip of platform processed, it is artificial to disconnect short dot and connect the plug-in strip with test supervisory control desk when carrying out the measurement of firing cable circuit,
Indicator light also can not correctly reflect current working condition.Therefore, Solid Rocket Motor Ground Test installation and debugging are being carried out
During fire trial, there are security risks.
Summary of the invention
The technical problem to be solved by the present invention is to a kind of multi-joint self-lock switch of Solid Rocket Motor Ground Test, with solution
Solid-rocket determine during engine test installation and debugging 100% short circuit of igniter and in ignition circuit resistance measurement again
The problem of data can accurately, reliable be obtained.
To solve, the technical solution adopted by the present invention are as follows: interview to a kind of solid propellant rocket
The multi-joint self-lock switch tested, including power supply, quadruple switch, indicator light, the quadruple switch are divided into K1, K2, K3 and K4 tetra- and open
It closes, K1 switch is connected in parallel on the igniting both ends cable Xia Kou with igniter；K2 and K3 switch be separately mounted to connection ignition controller and
On two igniting cables of igniter；K4 is connected to form pilot lamp loop with power supply, indicator light；Quadruple switch is mounted on work
Scene, indicator light and ignition controller are mounted on test supervisory control desk.
The present invention proposes multi-joint self-locking open according to the application demand of the multi-joint self-lock switch of Solid Rocket Motor Ground Test
The design requirement of pass designs multi-joint self-lock switch structure, selects suitable electronic device, and is installed, experimental test and tested
It is in kind to form the multi-joint self-lock switch of Solid Rocket Motor Ground Test to meet test demand for card.
The present invention carries out dependence test verifying, and meets following index:
1) it is divided into field operation and igniting two states of operation；
2) when being in field operation state, ignition circuit and test supervisory control desk are disconnected, and the igniting cable at scene is in
Short-circuit condition；
3) when in igniting job state, ignition circuit and test supervisory control desk are connected, and the igniting cable short circuit at scene
State is eliminated；
4) job state can be transmitted to test supervisory control desk automatically；
Meet Solid Rocket Motor Ground Test fire trial requirement.
Beneficial effect
The multi-joint self-lock switch of a kind of Solid Rocket Motor Ground Test of the invention, realizes engine test installation and debugging
It 100% short circuit of igniter and can accurately, reliable be tested again in ignition circuit resistance measurement and real-time display is worked as in journey
The effect of state ensures going on smoothly for Solid Rocket Motor Ground Test.Solid Rocket Engine Test is multi-joint self-locking to be opened
Pass also can be applied to that defense military industrial circle is other similar self-locking and status display problem.
Detailed description of the invention:
The multi-joint self-locking switch circuit figure of Fig. 1 Solid Rocket Motor Ground Test.
Specific embodiment:
The present invention is further elaborated on combined with specific embodiments below.
The multi-joint self-locking switch circuit structure of Solid Rocket Motor Ground Test of the invention, is mainly opened by power supply, tetrad
Close (wherein three be open-circuit condition, remaining one be closed state), indicator light, the composition such as connecting cable, structure such as Fig. 1 institute
Show.
K1 switch is in parallel with the igniting both ends cable Xia Kou, and K2, K3 switch are connected with every single line of igniting cable respectively,
K4 access pilot lamp loop is connected with power supply, indicator light.When quadruple switch is in current state, igniter both ends due to
K1 switch in parallel, K1 switch are short-circuit condition, i.e., igniter is also short-circuit condition, and K2, K3 switch are in open-circuit condition, therefore light a fire
Cable and test supervisory control desk are detached from, and K4 switch is open-circuit condition, therefore pilot lamp power access failure, indicator light do not work, at this time
It is shown as field adjustable state；When quadruple switch is in rollover states, igniter both ends due to K1 switch in parallel, K1 switch
For open-circuit condition, igniter insurance is opened, and K2, K3 switch are in closed state, therefore cable of lighting a fire is connected with test supervisory control desk
It connects, test supervisory control desk can carry out fire-working article test and ignition control to igniter, and K4 switch is closed state, therefore indicator light
Power supply is connected, and indicator light works normally, and is shown as test carry out state at this time.
Mode is applied in combination using quadruple switch in the present invention.Switch K1 realizes short to the execute-in-place of priming system (igniter)
Road, experiment work cut-out function.Switch K2, K3 are realized to the open circuit of igniting cable execute-in-place, experiment work turn-on power loss.Switch
K4 realizes that trystate indicates function, and indicator light, which is connected, indicates experiment work state, and indicator light does not work and is shown as execute-in-place
State.
Verification experimental verification test is carried out with the multi-joint self-lock switch of Solid Rocket Motor Ground Test, and to device indicator light
State is examined, and result phase is as shown in Table 1:
1 test result analysis of table
Available by table 1, the present invention is in carrying out verification experimental verification test, and quadruple switch state action is normal, LED status
Normally.Therefore, design result is feasible, meets test requirements document.
Current successful application during Solid Rocket Motor Ground Test realizes engine test installation
100% short circuit of igniter, can accurately, reliable obtain data in ignition circuit resistance measurement again, disappear in debugging process
In addition to live priming system operation safety hidden danger, meet Solid Rocket Motor Ground Test requirement, starts in current solid-rocket
It is indispensable in machine ground firing.
