Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described. Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
The present invention relates to a kind of high-voltage generator circuit, including the input voltage module being sequentially connected with, rectification circuit module, smothing filtering module, detection module and output module. The device is mainly used for the transmitting of X ray, what output module was corresponding is exactly the device for the X ray after filtering is applied to correspondence.
As it is shown in figure 1, in the present embodiment, input voltage module adopts three-phase alternating-current supply.
Smothing filtering module adopts the filter capacitor that two or more is in parallel, and the branch road of each filter capacitor is provided with current sensor, and current sensor is arranged between filter capacitor and the detection module of correspondence. The electric capacity of each filter capacitor is equal. Embodiment adopts three filter capacitors.
Smothing filtering module couples with detection module. Detection module includes current transformer, resistive module and alarm module, and the armature winding of current transformer couples with filter capacitor, and the secondary windings of current transformer couples with resistive module, one end ground connection of resistive module.
Alarm module and each current sensor are all in parallel, and alarm module includes buzzer and LED.
This device converts three-phase alternating current to unidirectional current by rectification circuit module, in order to ensure the quality of X ray, by filter capacitor, unidirectional current is removed ripple. Owing to being all in parallel between each filter capacitor, once one of them damages, circuit module over loading below can be made, be chronically under such environment it is possible to equipment is produced damage, cause that medical cost increases. Therefore, here by adding current sensor on the circuit of each filter capacitor, being carried out monitoring, once the electric capacity of correspondence is breakdown, corresponding current sensor will detect have electric current to produce on this circuit, thus triggering the alarm device of correspondence. So can remind its internal damaged condition of user in time, can rapidly targetedly position when also can be easy to follow-up maintenance simultaneously.
In this configuration, current sensor can also change voltage sensor into, and now voltage sensor is the two ends of the filter capacitor being connected on correspondence, once filter capacitor punctures, voltage sensor will measure the change of voltage, thus triggering alarm. As in figure 2 it is shown, be the partial circuit schematic diagram adopting current sensor, including detection module and filtration module, wherein, A represents that current sensor, B represent alarm module, and input voltage module, rectification circuit module are all adopt common circuit.
In this device, the buzzer in alarm module and LED can individually adopt and can also adopt simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
