Problems solved by technology

The manufacturing process of traditional wave-tuning resistors has the following disadvantages: 1. It needs to be painted, which is not environmentally friendly, and the working environment is harmful. Affects product thickness, poor product consistency, too much dependence on manual operation, and relatively high requirements for employee experience; in addition, processes such as puttying and polishing are very time-consuming, labor-intensive for employees, and production efficiency is low; 3. Operating procedures Many, further reduce production efficiency, labor consumption is large, and production cost is high

Embodiment 1

[0067] This embodiment includes a base part and a packaging case for encapsulating the base part; the base part includes an epoxy board frame 1, a conductive plate 2 fixed to both ends of the epoxy board frame 1, wound around the epoxy board frame 1, and connected to the conductive plate 2 resistance wire 3 forming a good electrical connection; the package housing includes a hollow body 4 and an end cap that covers the hollow body 4, the base part is hidden in the package housing, and its two conductive plates 2 protrude from both ends of the cover. The electronic potting glue that integrates the base part, the hollow body 4 and the cover is potted in the packaging shell, and the electronic potting glue is an electronic potting glue that is in a hard state after curing. In this embodiment, a position-limiting structure is provided in the hollow body 4 to limit the position of the epoxy board frame 1 , and the position-limiting structure is the position-limiting protrusion 9 . ...

Embodiment 2

[0079] In this embodiment, on the basis of Embodiment 1, a contact protrusion 14 is designed on the inner side of the airtight end cap 7 and the sealing end cap 8 to facilitate the contact between the end cap and the electronic potting glue, that is, the contact protrusion can be completely immersed in the electronic potting. Inside the sealant. The electronic potting glue in this embodiment is hard epoxy resin glue at room temperature. After curing, the hard epoxy resin glue at room temperature has very high mechanical strength, which can effectively ensure the structural strength of the product and the durability of the product.

[0080] In addition, a groove 13 is provided on the inner wall of the hollow body 4 to facilitate the flow of the electronic encapsulant. When the resistance value of the wave tuning resistor is relatively high, the thickness of the enameled wire wound will increase, and the increase in thickness will inevitably affect the space in the hollow body 4...

Description

technical field [0001] The invention belongs to the technical field of high-voltage test equipment, and in particular relates to a device with ingenious design, stable structure, high product reliability, healthy, environmentally friendly and pollution-free manufacturing process, greatly simplified production process, fewer manufacturing process steps, and high production efficiency. A wave-tuning resistor with improved amplitude, low manufacturing cost, and wide application, and a manufacturing process thereof. Background technique [0002] The high-voltage electrical equipment in the power system will inevitably be subjected to lightning impulses, so it is necessary to use an impulse voltage generator to conduct lightning impulse tests during type tests or factory tests. IEC60060-1 stipulates the standard lightning impulse waveform as follows: the wave front time Tf is 1.2us, the half peak time Tt is 50us, and the allowable deviation is ±30% and ±20% respectively. However...
