Abstract
The invention discloses poly- self-checking device at the beginning of a kind of line, including circular insulating base and conducting rod, the insulating base along its axis is provided with through hole, the conducting rod passes through the through hole, the side of the insulating base, which is provided with annular groove, the groove, is in series with multiple resistance, and the upper surface of the insulating base is provided with the contact consistent with the resistance quantity, and each contact correspondence one resistance of connection, the upper end of the conducting rod is connected with the contact pin that can be connected with the contact.By by after multiple resistant series according in the annular groove of insulating base, the rotation of contact pin is driven using conducting rod, form a special toroidal rheostat, pass through the rotational angle of step motor control conducting rod, the size of control access resistance, it is achieved thereby that the regulation of the access resistance focused on to line head.
Description
Technical field
The present invention relates to poly- self-checking device at the beginning of a kind of line, belong to accelerator line lead-out process field.
Background technology
The line of current accelerator draws the primary focus voltage in head and uses fixed partial pressure mode mostly, i.e., by accelerating
Pipe magnet ring two ends simultaneously connect the focus voltage needed for pressure divider resistance partial pressure is obtained.Which meets general energy working range and become
Change little, the occasion that primary focusing need not be adjusted.
With broadening for accelerator energy job requirement scope, line draws the primary focus voltage in head as fixed always not
Become, be just difficult to meet each energy section line primary and focus on to meet the requirements.It will certainly so be brought necessarily to the application of accelerator
Limitation.
The content of the invention
The technical problems to be solved by the invention are to provide poly- self-checking device at the beginning of a kind of line, using stepper motor outside
Plus the special transmission mechanism of self-control and slide rheostat structure are combined, and devise a kind of primary focus voltage adjustable apparatus.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
Poly- self-checking device at the beginning of a kind of line, including circular insulating base and conducting rod, the insulating base along its axle
Line is provided with through hole, and the conducting rod passes through the through hole, and the side of the insulating base is provided with annular groove, the groove
Multiple resistance are in series with, the upper surface of the insulating base is provided with the contact consistent with the resistance quantity, and each contact pair
A resistance should be connected, the upper end of the conducting rod is connected with the contact pin that can be connected with the contact.
Poly- self-checking device at the beginning of a kind of foregoing line, it is characterised in that：The conducting rod passes through drive link and stepping
Motor is connected.
Poly- self-checking device at the beginning of a kind of foregoing line, it is characterised in that：The drive link by shaft coupling with it is described
Stepper motor is connected, and the stepper motor is connected with controller.
Poly- self-checking device at the beginning of a kind of foregoing line, it is characterised in that：The resistance is set in qually spaced in described exhausted
In the annular groove of the side of edge seat.
The beneficial effects of the invention are as follows：By, according in the annular groove of insulating base, will be utilized after multiple resistant series
