Background technology
Power system need to be assembled various detection means and tester during live high-voltage test；It is but existing
Test platform typically all use container body formula or vehicular, the control of its platform building needs separate operations, and control unit
It is more dispersed, independently of each other；This requires that operating personnel are very familiar to platform building step, and personnel are needed in build process
In operation, whether viewing test instrument is installed in place, and whether Pass Test requires platform building, operates very inconvenient,
Therefore, we have developed a kind of high-voltage test platform builds control system automatically, cumbersome group between various equipment is avoided
Dress, eliminates potential safety hazard, and building for test platform is realized that programme-control is safe and efficient, simple and convenient.
The content of the invention
A kind of high-voltage test platform is provided the invention aims to overcome the deficiencies in the prior art and builds control automatically
System processed, cumbersome assembling between various equipment is avoided, eliminates potential safety hazard, and building for test platform is realized program
Control it is safe and efficient, it is simple and convenient.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of high-voltage test platform builds control automatically
System, include sensing detection circuit, power drive circuitry, protection circuit and the man machine operation interface being connected respectively with controller；
The safety signal and human-machine operation that position detection signal that the controller transmits according to sensing detection circuit, protection circuit transmit
The switching signal control power drive circuitry work that interface is transmitted, so that power drive circuitry motor and hydraulic system work
Make to complete building for test platform energy.
Preferably, the sensing detection circuit includes position sensor, pressure sensor and horizontal check instrument, wherein position
Sensor is used for detecting the position of each moving component in test platform build process, and pressure sensor and horizontal check instrument are used for protecting
Demonstrate,prove the horizontality in working platform face.
Preferably, the position sensor includes travel switch and proximity switch.
Preferably, the protection circuit provides personnel and swarms into protection, overload protection and ground protection.
Preferably, control menu, running status menu, annunciator menu and failure are provided with the man machine operation interface to look into
Ask menu.
Preferably, the controller is controlled using PLC or single-chip microcomputer.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
High-voltage test platform of the present invention builds control system and avoids cumbersome group between various equipment automatically
Dress, makes building for test platform more simple and convenient, carries out only selecting by man-machine interface when test platform is built at the scene
Test type, platform will quickly be built automatically.
