Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage pulse equipment, and more specifically, it relates to a high-adaptability fractional ratio pulse transformer structure. Background Art

[0002] Whether it is a radar transmitter or a radio frequency power amplifier in an accelerator, a high-voltage pulse modulator is required to provide high-voltage pulses that meet the requirements. The fractional ratio pulse transformer uses a single-turn primary winding and multiple secondary magnetic cores in combination, which can ensure that the primary unit circuit has advantages such as lower working voltage, modular components, and unit grounding, while also achieving low leakage inductance, low distributed capacitance of the secondary winding, low inductance of the discharge unit and transmission loop, making the fractional ratio pulse transformer a core competitive product in the high-voltage pulse modulator industry. However, due to different technical parameters and different klystrons that need to be installed, different klystrons require different pulse transformers to be adapted, which greatly increases the production cost. At the same time, since this type of pulse transformer is generally large in size, compared with general small transformers, its disassembly and installation are more complex, and the repair is more complex when some protective components are damaged. Therefore, there is an improvement need in the existing technology.

[0003] There is a technology with the name "pulse transformer" and the publication number "CN109119228A" in the existing technology. This technology includes a drum core (20), windings (W1 to W4) wound around the winding part (23) of the drum core, and a plate-shaped core (30) fixed to the drum core in a manner that faces the surface (21t) of the first flange part (21) and the surface (22t) of the second flange part (22) of the drum core. When the area of the yz cross-section of the winding part is S1 and the relative area of the plate-shaped core and the surface (21t) or (22t) of the flange part is S2, the value of S1 / S2 is 0.19 or more and less than 0.47. Since the value of S1 / S2 is set to be less than 0.47, the insertion loss can be reduced compared with a general pulse transformer by using the effect of shortening the winding length. Moreover, since the value of S1 / S2 is set to be 0.19 or more, the reduction of inductance can be suppressed to, for example, 20% or less.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is: aiming at the deficiencies of the existing technology, to provide a high-adaptability fractional ratio pulse transformer structure with a simple structure, which realizes the switching of the number of turns of the secondary coil according to requirements when different technical parameters are involved through the gear adjustment design of the main transformer, and conducts the adapter design for the klystron base, so as to adapt to the installation requirements of different klystrons.

[0012] The cathode copper plate includes a first cathode copper plate and a second cathode copper plate. The anode copper plate includes a first anode copper plate and a second anode copper plate. The first cathode copper plate is connected to the second cathode copper plate through a klystron base support rod; the cathode tube pins include a first cathode tube pin and a second cathode tube pin, and the anode tube pins include a first anode tube pin and a second anode tube pin.

[0013] The bottom of the filament assembly is connected to the first cathode copper plate through the first cathode tube pin, and the bottom of the filament assembly is connected to the first anode copper plate through the first anode tube pin. A second cathode tube pin is arranged on the second cathode copper plate, and a second anode tube pin is arranged on the second anode copper plate.
