Description

Technical Field

[0001] The utility model relates to the technical field of filament power supplies, in particular to a filament power supply for an electron accelerator. Background Art

[0002] The filament power supply uses advanced switching power supply circuit and adaptive technology. It can automatically determine the internal resistance of high-power electron tubes to smooth the voltage and make the high-power electron tubes work in a high-precision state. It solves various faults caused by the small cold resistance of high-power electron tube filaments that are easily affected by current shocks, thereby extending the service life of the electron tubes.

[0003] The filament power supply is an alternating, regulated current source. To improve the transmitter's ground interference rejection ratio, the RF signal must be temporally nested within the beam pulse. Therefore, the filament voltage and current provided by the filament power supply are alternating pulses synchronized with the radar transmit pulses. The filament voltage output by the filament power supply is fed through a filament intermediate transformer to the low-voltage terminals of the dual secondary windings of a high-voltage pulse transformer. This voltage is then fed through the pulse transformer's secondary windings and, at the high-voltage terminals, to the primary of the filament transformer. The secondary of the filament transformer is then connected to the klystron filaments in the radar transmitter, powering the filaments.

[0004] Prior Art: CN220475977U A filament power supply for an electron accelerator. During installation, a handle is operated to control a driving gear to rotate a chain, which in turn drives two driven wheels to rotate, thereby achieving synchronous rotation of two opposing screws. Next, the pulling blocks and push-pull arms on the two opposing screws also operate synchronously, thereby achieving synchronous movement of the left and right clamping plates to clamp the filament power supply. Bolts are then inserted into the threaded grooves to firmly secure the short plates and prevent them from sliding. This ensures stable fixation of the filament power supply and a fixing effect comparable to that of traditional screw fixing methods. However, the above patent still has shortcomings: when fixing the filament power supply, manual labor is required to turn the handle and control the chain rotation. Only after a series of steps are completed can the filament power supply be fixed. This method is not only time-consuming and labor-intensive, but also the manual operation cannot control the force, which can easily damage or cause injury to the operator. Traditional filament power supplies are not equipped with a shock-absorbing device during installation, and are easily damaged by vibration during special use. Therefore, a filament power supply for an electron accelerator is needed to improve the above problems. Utility Model Content

The fixing component 2 includes a base 201, and a telescopic rod 202 is installed on the side of the base 201. The output end of the telescopic rod 202 is fixedly connected to an L-shaped card plate 203. The telescopic rod 202 is pushed out to drive the L-shaped card plate 203 to clamp and fix the filament power supply body 109. This method is simple and convenient, and has high efficiency. It saves the time of manual twisting and increases the efficiency of installation.

By fixing the telescopic rod 202, it can be retracted when not needed, thereby saving space.

[0029] Among them, there are four bases 201, telescopic rods 202 and L-shaped card plates 203. The interior of the inner box 102 is fixedly connected to a temperature sensor 103.
