Abstract
The utility model discloses a capacitive voltage divider. The capacitive voltage divider is characterized in that an upper high voltage polar plate is arranged within an outer cylinder, connected with an adjusting rod and fixed at the top end of the outer cylinder; a lower high voltage polar plate is arranged at the bottom of the outer cylinder and corresponds to the upper high voltage polar plate in position; and the lower high voltage polar plate is connected with a circuit unit; because the structure is adopted, the capacitive voltage divider disclosed by the utility model has the advantages of simple structure, low production cost and convenience for mounting; the voltage division ratio can be flexibly adjusted to adapt to different occasions; and through being filled with transformer oil, the layout of the whole voltage divider is more flexible.
Description
Technical field
The utility model relates to the high voltage pulse modulator field, particularly a kind of capacitive divider.
Background technology
High voltage pulse modulator has been widely used on the microwave source with equipment such as the electron accelerator of pulse mode work, radar transmitter and safety check, flaw detections.
The overwhelming majority need use capacitive divider on highpowerpulse equipment at present; But all need integral body to be placed in the transformer oil could to guarantee its requirement of withstand voltage though these voltage divider measuring accuracy are higher; And the voltage divider arrangement relative fixed, its intrinsic standoff ratio can't be regulated.
A kind of novel capacitive divider is provided, and making its intrinsic standoff ratio can flexible be the problem that the prior art needs solve with the demand that adapts to different occasions.
The utility model content
The utility model technical matters to be solved is, a kind of capacitive divider is provided, make its intrinsic standoff ratio can flexible to adapt to the demand of different occasions.
For achieving the above object, the technical scheme of the utility model is that a kind of capacitive divider is characterized in that: described voltage divider is that the inside of urceolus is provided with high-pressure polar plate and is connected with the top that adjuster bar is fixed to urceolus; The bottom of urceolus is provided with down high-pressure polar plate, and the position is corresponding with the position of last high-pressure polar plate; Following high-pressure polar plate is connected to circuit unit, thereby goes up between high-pressure polar plate and the following high-pressure polar plate apart from the intrinsic standoff ratio of realizing regulating voltage divider through the adjuster bar adjusting.
For being threaded, the junction is the interlocking structure of two nuts between described adjuster bar and the urceolus, thereby realizes fixing to the adjuster bar height.
Described urceolus is the sealing barrel-like structure, and the top of urceolus is provided with oil hole, and oil hole is provided with the screw shutoff, thereby convenient to urceolus inside injection transformer oil.
Be provided with O-ring seal between described screw and the oil hole, guaranteed that transformer oil does not leak.
The described two sides of high-pressure polar plate down is equipped with supporting plate, is filled with methenyl choloride between the supporting plate.
Described circuit unit inserts BNC connector after high-pressure polar plate is connected with capacitor C 1, resistance R 1 down; Capacitor C 1 is through capacitor C 2 ground connection.
A kind of capacitive divider owing to adopt said structure, this voltage divider has the following advantages: 1, its intrinsic standoff ratio can flexible to adapt to different occasions; 2, transformer oil is filled by portion within it, makes that the layout of whole voltage divider is more flexible; 3, simple in structure, production cost is low, and it is convenient to install.

Embodiment
As shown in Figure 1, the utility model is that the inside of urceolus 1 is provided with high-pressure polar plate 2 and is connected with the top that adjuster bar 4 is fixed to urceolus 1; The bottom of urceolus 1 is provided with down high-pressure polar plate 3, and the position is corresponding with the position of last high-pressure polar plate 2; Following high-pressure polar plate 3 is connected to circuit unit 5, thereby goes up between high-pressure polar plate 2 and the following high-pressure polar plate 3 apart from the intrinsic standoff ratio of realizing regulating voltage divider through adjuster bar 4 adjustings.For being threaded, the junction is the interlocking structure of two nuts 9 between adjuster bar 4 and the urceolus 1, thereby realizes fixing to the adjuster bar height.
Urceolus 1 is the sealing barrel-like structure, and the top of urceolus 1 is provided with oil hole, and oil hole is provided with screw 7 shutoff, thereby convenient to urceolus inside injection transformer oil.Be provided with O-ring seal 8 between screw 7 and the oil hole, guaranteed that transformer oil do not reveal.
The two sides of following high-pressure polar plate 3 is equipped with supporting plate 6, is filled with methenyl choloride between supporting plate 6 and the urceolus 1.
The utility model is through regulating the distance that goes up high-pressure polar plate 2 and urceolus 1 top and using nut lock; Because urceolus 1 top center hole is a threaded hole; When regulating externally the screw thread place of wiring with the mode of double nut interlocking will go up high-pressure polar plate 2 upwards with adjusting downwards, can effectively guarantee to be regulated apart from match operation person requirement.
Last high-pressure polar plate 2, high-pressure polar plate 3 adopts the copper coin manufacturings and the surface smoothness of material is had relatively high expectations to reach and is advisable more than 0.8 down; Supporting plate 6 adopts the higher organic glass manufacturing of transparency; Assembling is glued together with methenyl choloride between each organic glass, guarantees that gummed is fine and close non-leakage.Use is gone in urceolus 1 chamber and to be injected withstand voltage transformer oil at ~ 35kv/mm, screw on screw 7 and O-ring seal 8.
The intrinsic standoff ratio of the capacitive divider that the utility model can be regulated, thus and can improve usable range greatly with oil immersed type with what voltage divider was made dry type according to the requirement of use occasion.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the utility model technical scheme to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
