Description

Technical Field

[0001] This invention relates to pulse power technology, specifically to a cantilever support fixture and a method for installing the inner and outer cylinders of a coaxial pulse forming line using the cantilever support fixture. Background Technology

[0002] The Tesla transformer-type pulse power source mainly consists of a coaxial pulse forming line, a gas switch, a transmission line, and a diode load. The coaxial pulse forming line is mainly composed of an outer forming line cylinder and an inner forming line cylinder. The inner forming line cylinder is mostly insulated and supported by materials such as plexiglass and nylon in both radial and axial directions, and is coaxial with the outer forming line cylinder.

[0003] Figure 1 A coaxial pulse forming line includes an outer forming line cylinder 01, a tail cap 02, a tail end cap 03, a switch outer cylinder 04, an inner forming line cylinder 05, a tail end insulator 06, an insulating support plate 07, a switch cathode base 08, a switch cathode 09, and a support wheel 010. The front end of the inner forming line cylinder 05 is connected to the switch cathode base 08, and the switch cathode 09 is mounted on the switch cathode base 08. The tail end of the inner forming line cylinder 05 is fixedly connected to one end of the tail end insulator 06, and the other end of the tail end insulator 06 is disposed inside the tail cap 02. The tail end cap 03 is pressed onto the other end face of the tail end insulator 06 and fixed to the outer surface of the tail end cap 02; the tail end cap 02 is connected to the flange of the forming line outer cylinder 01, and the bottom of the flange connection part is provided with a support wheel 010; the insulating support plate 07 is set at the front end of the forming line inner cylinder 05, and its outer circle is installed in the flange of the forming line outer cylinder 01 and the switch outer cylinder 04; the forming line outer cylinder 01 is connected to the flange of the switch outer cylinder 04 and the outer circle of the insulating support plate 07 is pressed and fixed, and the bottom of the flange connection part is provided with a support wheel 010.

[0004] Due to the need for further insulation, the installation of the inner cylinder assembly becomes more difficult when a horizontal cantilever connection is used at the tail end of the inner cylinder 05. For example... Figure 1 As shown, the tail insulator 06 can only be assembled with the inner cylinder 05 of the forming line after the tail cover 02 is installed. If the conventional two-end support method is used for assembly, the tail end (i.e., the cantilever end) of the inner cylinder 05 will lack a support point when installing the tail insulator, making coaxial installation impossible. Therefore, a special tooling is required to complete the integration of the inner and outer cylinders of the forming line. However, the diameter of the opening at the tail end of the inner cylinder 05 is small, while the diameter at the straight section is relatively large, making the tooling design and leveling coaxial installation of the inner cylinder 05 directly insertable into it quite difficult. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem that when the inner cylinder of the forming line is installed using a horizontal cantilever connection, the cantilever end has no support point and cannot be coaxially assembled with the outer cylinder of the forming line.

[0075] The advantages of this invention compared to the prior art are:

[0076] 1. The present invention provides a method for installing inner and outer cylinders of a coaxial pulse forming line using a cantilever support fixture. The cantilever support rod of the cantilever support fixture is inserted into the inner cylinder of the forming line, and the height and horizontal direction of both ends of the inner cylinder of the forming line can be adjusted respectively. This solves the problem that the inner cylinder of the forming line, which is cantilevered at one end, has no support point at the cantilever end and cannot be coaxially assembled with the outer cylinder of the forming line during installation.

[0077] 2. The present invention provides a method for installing the inner and outer cylinders of a coaxial pulse forming line using a cantilever support fixture. The method adopts a step-by-step coaxial installation approach. First, the inner cylinder of the forming line is coaxially installed with the tail insulator and tail cover by adjusting with the cantilever support fixture. Then, the inner cylinder of the forming line is installed with the insulating support plate and the outer cylinder of the forming line by adjusting with the cantilever support fixture. This solves the problem that the two ends are not easy to be leveled simultaneously for coaxial installation due to the unequal inner diameter of the inner cylinder of the forming line.

[0078] 3. The cantilever support fixture provided by this invention, through the combined operation of its main support component and tail-end pressing component, enables adjustment of the height, level, pitch, and horizontal rotation of the cantilever support rod, thereby achieving adjustment of the inner cylinder of the forming line in any orientation, greatly reducing the difficulty of coaxial installation. Furthermore, the main support component, placed on a counterweight platform, acts as a counterweight, increasing the safety factor of the counterweight.

[0079] 4. The cantilever support fixture provided by the present invention has a fan-shaped support head at the front end, which can reduce the unevenness of the cantilever support rod after it is inserted into the inner cylinder of the forming line for support. The fan shape is chosen instead of a circle, which can maximize the diameter of the fan shape while making it easy to enter from the small opening at the front end of the forming line, thereby improving the support level of the inner cylinder of the forming line.
