Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
The high voltage withstanding water-cooled resistor of one kind of the present embodiment, as depicted in figs. 1 and 2, including alumina ceramic tube 1, porcelain
1 outer surface of pipe is wound with resistance wire not shown in the figure, and the outside of porcelain tube 1 and resistance wire is successively cased with the quartz sand bed of material 2 and (fills out
The bed of material), mica casing 3 (i.e. insulating sleeve) and metal tube 4, so then completely cut off between resistance wire and atmosphere, in high-voltage case
Under will not puncture, meet the use environment demand of high voltage, and resistance wire is not easy to be oxidized, and improves service life.Metal
The both ends of pipe 4 are provided with outlet hole 41, and mica casing 3 is provided with the transitional pore 31 being aligned with outlet hole 41, the both ends of resistance wire
It is pierced by respectively from the transitional pore of corresponding end 31 and outlet hole 41.Stone is equipped between the end of porcelain tube 1 and the end of mica casing 3
English slurry ring 5 (i.e. insulation encapsulated ring), for the quartz sand bed of material 2 to be encapsulated between porcelain tube 1 and mica casing 3.In resistance wire
Both ends be pierced by from outlet hole 41 after, pour into quartz slurry ring 5 and be just aligned and block transitional pore 31 and outlet hole 41, and
It can be with the end of fixed resistance silk, multi-purpose content.In practice, 3 end of mica casing is readily modified as resisting quartz slurry ring 5, this
Sample is just not necessarily to out transitional pore 31.
The both ends of porcelain tube 1 are designed with sealed rubber ring 6 and ring end cap 7, and ring end cap 7 is threaded with the inside with porcelain tube 1
The logical liquid connector of connection, the logical liquid connector at both ends is respectively as water inlet 8 and water outlet 9, so that it is logical to form water flow in porcelain tube 1
Road.Sealed rubber ring 6 coats the end of porcelain tube 1, and the inner wall of metal tube 4 resists the lateral surface of sealed rubber ring 6, and ring end cap 7 resists close
The medial surface of sealing ring 6, ring end cap 7 is threadedly coupled the outer surface of metal tube 4, thus by sealed rubber ring 6, metal tube 4 and porcelain tube 1
It clamps, it is ensured that loosening will not be worn between all parts, sealing stability is good.By upper structure it is found that the liquid in porcelain tube 1 reaches
The path of resistance wire is hindered by sealed rubber ring 6, quartz slurry ring 5 and this triple seal of packing layer, realizes good sealing effect
Fruit.Sealed rubber ring 6 also acts as the effect of buffering, when resistor is shaken, porcelain tube 1 is protected not rupture.
When manufacturing above-mentioned resistor, manufacturing process is comprised the steps of:
Spooling step: resistance tube is made in the helically coiling resistance wire on porcelain tube 1；
Precession step: resistance tube is screwed in into mica casing 3 and then by the end of resistance wire from the outlet hole 41 of corresponding end
It draws；
Encapsulating step: pouring into quartzy slurry between the lower end of porcelain tube 1 and the lower end of mica casing 3 in Fig. 1, Gu
Change the quartz slurry ring 5 for forming lower end, and the end of resistance wire is coated and fixed quartz slurry ring 5；
It fills sand step: pouring into quartz sand from the upper end of porcelain tube 1 toward between porcelain tube 1 and mica casing 3, until filling up to form stone
The sand bed of material 2；
Secondary encapsulating step: pouring into quartzy slurry between the front end of porcelain tube 1 and the front end of mica casing 3, solidifies shape
At the quartz slurry ring 5 of upper end；
Socket step: by 6 sets of sealed rubber ring in 1 end of porcelain tube, ring end cap 7 is then screwed in again, is finally loaded onto ring end cap 7
Logical liquid connector is the assembling for completing entire resistor.
In practice, mica casing 3 could alternatively be gold film, can also have preferable pressure-resistant insulation performance.Quartz sand
The bed of material 2 could alternatively be the high insulating materials such as epoxy resin or layer of silica gel.In general, insulating materials insulation performance is better,
Heat resistance is poorer, and the present embodiment is poor for high insulating materials, the heat resistance such as insulate and select quartz sand, it is therefore necessary to
Heat is taken away by water cooling, the heat overwhelming majority that resistance wire generates is taken away by water, realizes water cooling and height insulation is high voltage bearing
It organically combines.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
