Abstract
The utility model discloses a water-cooled ceramic vacuum capacitor which is composed of a mover assembly, a stator assembly, a vacuum chamber, a corrugated pipe, and a ceramic casing. A waterstop ring is arranged between a pull rod and a guide sleeve, the top of the pull rod is provided with a water inlet, a water outlet is arranged below the water inlet, the bottom of the pull rod is provided with a through hole, and thus a cooling water path is formed. A plurality of screw rods are uniformly distributed and installed around an axle center at the inner side near the corrugated pipe, or a screening cylinder is coaxially arranged at the inner side near the corrugated pipe, and positioning electrode collars are respectively concentrically arranged on a mover disk and a stator disk. The utility model has the characteristics of high voltage resistance, large radio-frequency current, large reactive power, etc. When the utility model is produced and processed, the positioning is easy, the utility model can be used for the field of broadcast communication equipment, medical devices, and military, etc., and the utility model can also be used for equipment of high frequency dielectric heating and high-voltage testing, etc. The utility model is especially suitable for an oscillating circuit and an amplifying circuit, by using the capacitor of the utility model, a transmitter which has a smaller size, stabler and superior performance, and larger unit power can be produced.
Description
Technical field
The utility model relates to a kind of ceramic vacuum capacitor, relates in particular to a kind of water-cooled ceramic vacuum capacitor.
Background technology
General ceramic vacuum capacitor is withstand voltage be 2KV-50KV, and radio-frequency current is below the 400A, and the temperature rise of product is by the solution of radiating modes such as cross-ventilation, radiation, thereby its withstand voltage and radio-frequency current is subjected to certain limitation.And when production and processing, what adopt usually is the concentricity that lathe centering locate mode guarantees two arrays of electrodes, but exists with a defective: 1, the requirement on machining accuracy to part (particularly mover dish, stator discs) is very high; 2, the competency profiling to the product assembler is very high.Because the consistency of the clamping precision of product is difficult to guarantee in the process of lathe clamping.For guaranteeing assembly precision, also need a high-precision lathe.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of prior art, a kind of withstand voltage height, water-cooled ceramic vacuum capacitor that radio-frequency current is big are provided.
The utility model is realized by following scheme: be made up of mover group, stator pack, vacuum chamber, bellows and ceramic package, be provided with waterstop ring between pull bar and guide pin bushing, the top is provided with water inlet, and the water inlet below is provided with delivery port, the pull bar bottom is provided with through hole, thereby forms cooling-water duct.
The utility model is because the easiest eddy generation in ripple place of bellows, thus near the bellows inboard around uniform some screw rods or the coaxial shielding cylinder that is provided with installed in axle center, to reduce the eddy current generation.
The utility model is guaranteed the concentricity of two arrays of electrodes during for ease of general assembly, reduction is to the requirement of part processing precision, on mover dish and stator discs, be provided with the keeper electrode ring respectively with one heart, needing only during general assembly increases the consistency that one pair of positioning fixture just can guarantee the product precision, alleviate assembler's labour intensity, also can save a high precision machine tool.
The utility model is the supporting critical component of high power broadcast transmitter, compare with other conventional ceramic vacuum capacitor, have characteristics such as withstand voltage height, radio-frequency current is big, reactive power is big, during production and processing, locate easily, good concentricity is widely used in fields such as broadcast communication equipment, medical device and military affairs, also can be used in the equipment such as high-frequency dielectric heating and Hi-pot test.By the application of capacitor of the present utility model, it is littler to make volume, and performance is more stable, the transmitter more superior, that single-machine capacity is bigger.
