Embodiment one
Seeing Fig. 1, this figure is the structured flowchart of a kind of power supply unit that the embodiment of the present invention one provides.
The power supply unit that the present embodiment provides includes: for introducing the leading-in end 11 of the first power supply and being used for
The exit 12 that described first power supply is discharged.Described leading-in end 11 has conducting connecting part 110,
Described exit 12 has conducting connecting part 120.
In the present embodiment, described first power supply can be high-tension electricity, industrially, described high-tension electricity
Generally referring to alternating voltage is more than 1000V, or the voltage of more than DC voltage 1500V.Described
Target device is powered by one power supply by accessing described leading-in end 11, and described target device is permissible
It is the equipment needing high-tension electricity to be powered as electron linear accelerator is this,
In the present embodiment, in order to realize the safe and reliable high-tension electricity that utilizes, target device is powered,
And under powering-off state, described high-tension electricity is discharged, described power supply unit also includes conduction motion
Parts 13 and drive mechanism 14.
Described drive mechanism 14, under discharge mode, drives described conduction moving component 13 respectively
Enter with the conducting connecting part 110 of described leading-in end 11 and the conducting connecting part 120 of described exit 12
Row contact, to be constituted discharge loop with described leading-in end 11 and described exit 12.Described first electricity
Being discharged by described discharge loop in source, the electric current of the most described first power supply successively flows through described introducing

The microwave system (i.e. target device) of accelerator, carries out linear accelerating to electronics, produces X-ray.
If the pressurized equipment being used for pressurizeing described electron linear accelerator is suddenly because power-off occurs in fault,
Described microwave system cannot be continued as and continue power supply, but the most described microwave system still carries high pressure
Electricity, if discharging not in time, then may be because of equipment itself and human body being caused threat greatly.Or
Person, when described electron linear accelerator after hours, it is also desirable to described microwave system is carried out safety
Electric discharge.
In order to overcome above-mentioned technical problem, described the present embodiment is being put by utilizing described drive mechanism 14
Drive under power mode described conduction moving component 13 respectively with the conducting connecting part 110 of described leading-in end 11
Contact with the conducting connecting part 120 of described exit 12, occur suddenly breaking at described target device
In the case of electricity or needs discharge, it is possible to realize described first power supply is carried out the mesh of safe-discharge
's.
It addition, for the sake of security, when described target device not being powered on, described conduction motion portion
Part 13 respectively with the conducting connecting part 110 of described leading-in end 11 and being conductively connected of described exit 12
Part 120 contacts, and when target device is powered on by needs, the present embodiment is by utilizing described driving
Mechanism 14 drives described conduction moving component 13 to connect with the conduction of described leading-in end 11 in the electric mode
The conducting connecting part 120 of fitting 110 and/or described exit 12 separates, to utilize described first electricity
Source is to described target device safe power supply.
The conducting connecting part 110 of described leading-in end 11, the conduction of described exit 12 are not connected by the present invention
The structure of fitting 120 and described conduction moving component 13 is defined, as long as it is capable of contact
?.In the present embodiment, in order to make described conducting connecting part 110 and described conducting connecting part
120 are fully contacted with described conduction moving component 13, see Fig. 1, described conducting connecting part 110 He
Described conducting connecting part 120 is cylinder, and described conduction moving component 13 has can be with described cylinder
Show consideration for the U-lag closed, the radius of described U-lag cross section and the radius phase of described cylindrical cross section

With the limit switch 16 of contact as described first detection part, when described conduction moving component 13
When moving to a certain degree towards the direction of described electric magnet 140 along with described armature 141, trigger institute
The connecting rod stating limit switch 16 drives switch motion so that described connecting rod drives switch Guan Bi or disconnects,
Thus produce signal, i.e. a power supply signal.The generation of this power supply signal i.e. represents described conduction motion
Parts 13 are to separate with described conducting connecting part 110 and/or described conducting connecting part 120.In order to protect
Card detection reliability, described first detection part could be arranged to two or more (Fig. 2 and
Fig. 3 is provided with two limit switches 16), the most described first processor all have received these
The power supply signal that one detection part produces, just controls described first power supply according to described power supply signal and passes through
Described leading-in end 11 is powered to described target device.
In actual applications, described first detection part can also is that microswitch or sensor etc..Institute
Stating microswitch, also known as sensitive switch, its operation principle is similar to the limit switch of described contact,
Power is acted on action spring by actuated element (push-piece, button, lever, roller etc.) by outer mechanical force
On sheet, produce snap action when action reed is displaced to critical point, make the dynamic of action reed end touch
Point and fixed contact quick-make or disconnection.Described sensor can be displacement transducer, laser sensor
Deng, institute's displacement sensors is used for detecting the distance that described conduction moving component 13 moves, if movement
Distance reaches predeterminable range, then produce signal, represents that described conduction moving component 13 is and described conduction
Connector 110 and/or described conducting connecting part 120 separate；Described laser sensor can be arranged on pre-
If position, with generating laser with the use of, when described conduction moving component 13 moves to predeterminated position
Time, shelter from the laser that described generating laser sends, now laser sensing to described laser sensor
Device just can produce signal, represent described conduction moving component 13 be with described conducting connecting part 110 and
/ or described conducting connecting part 120 separate.
In actual applications, when entering after powering mode, need for the lasting offer high pressure of target device
Electricity, to enable a device to normally work.But, if continue during described high-tension electricity, time and disconnect,
Then target device possibly cannot normally work, it is possible that cause fire or other are right under serious conditions
People and equipment cause the situation of security threat, it is therefore desirable to further ensure that high-tension electricity in the electric mode
Power supply be safe and reliable.In order to realize this target, described power supply unit can also include the second inspection
Survey parts and the second processor (not shown in Fig. 2 and Fig. 3).Described second detection part is in institute
State under powering mode, detect described drive mechanism 14 whether drive described conduction moving component 13 from
Open the conducting connecting part 110 of described leading-in end 11 and/or the conducting connecting part 120 of described exit 12
After be maintained at predeterminated position, the most then be considered in safe power supply；If not, then it is assumed that power supply is not
Safety, now needs to send power-off signal to described second processor.Described second processor, is used for
Control described drive mechanism 14 according to described power-off signal and entered described electric discharge mould by described powering mode
Formula, i.e. described drive mechanism 14 drives described conduction moving component 13 to be conductively connected with described respectively
