Specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, the present invention is described in detail.
A kind of resistor with good insulating performance of the present embodiment, as shown in Figures 1 to 5, including base plate 1, Muscovitum
Boom 21, insulator 22, conducting ring 23 and the multi-disc resistor disc 3 being arranged above and below, the two ends of resistor disc 3 offer connecting hole 33, and two
Bar Muscovitum boom 21 strings together through 33 multi-disc resistor discs 3 of connecting hole, and insulator 22 and conducting ring 23 are all located in Muscovitum boom
21, insulator 22 is used for making insulation between adjacent two panels resistor disc 3, and conducting ring 23 makes in series or in parallel between multi-disc resistor disc 3
To meet different resistance demands, one end of Muscovitum boom 21 is bolted to connection with base plate 1.Conducting ring 23 adopts aluminium
Matter, has good electric conductivity and heat conductivity；Insulator 22 adopts 95 porcelain materials, and hardness is high, high temperature resistant, good insulation preformance.Resistor disc 3
For stainless steel 304 material, as shown in figure 3, resistor disc 3 punch forming has several grooves of the length direction arrangement along resistor disc 3
Mouth 31, so that the cross section of resistor disc 3 is curved in s shape Curved Continuous, the distance between two neighboring notch 31 is 2 millimeters.This electricity
Resistance device also includes soft phlogopite bar 5 and the mica clamping bar 4 being laid on the sidepiece upper and lower of resistor disc 3, and soft phlogopite bar 5 spreads
It is located between mica clamping bar 4 and resistor disc 3, that is, mica clamping bar 4, resistor disc 3 and soft phlogopite bar 5 are layered on top of each other.Soft gold
Mica strip 5 is passed down through several notches 31 successively upwards, and is spaced the upper and lower surface being laid on resistor disc 3, prevents
Under high current, electric power generation heat leads to adhesive, the stability of impact resistance.Soft phlogopite bar 5 is good insulation material
Material, and for an overall mica strip, relatively thin and have elasticity, laying is very convenient.Mica clamping bar 4 material is hard white clouds
Mother, insulation effect is good, and intensity is unlikely to deform enough.
Mica clamping bar 4, resistor disc 3 and soft phlogopite bar 5 a great problem being fixed as the invention each other,
Applicant has innovated following several fixed forms in practice:
One way in which is: as shown in Figure 1 to Figure 3, offers coaxial through-hole 32 in resistor disc 3 and mica clamping bar 4, using chicken
Eye rivet 6 passes through this through hole 32 and soft phlogopite bar 5 as fixture, thus resistor disc 3, soft phlogopite bar 5 and cloud
Female clamp bar 4 fixedly secures.The material of clavuss rivet 6 is h62 pyrite, and h62 brass conductive is good, has higher intensity, can protect
Card resistor disc 3 and the tightness of mica clamping bar 4, prevent loosening and driving notch and groove of mica clamping bar 4 and soft phlogopite bar 5
Slip between mouthful.Importantly, clavuss rivet 6 is substantially flush with the surface of mica clamping bar 4, will not be from mica clamping bar 4
Surface is substantially protruded, and the part of protrusion is extremely thin, will not reduce creep age distance, therefore neighbouring two panels resistor disc 3 logical
Need not deliberately stagger or align in hole 32, when processing the through hole 32 of resistor disc 3, can reduce the positional precision of through hole 32；In electricity
Without considered whether staggering of upper and lower resistor disc 3 through hole 32 during resistance device assembling, assembled from the arrangement of any resistor disc 3,
Processing and manufacturing is very convenient, greatly improves production efficiency.Most preferably this embodiment in practice.
Mica clamping bar 4 is insulator it is impossible to use the mode of welding；Resistor disc 3 can produce substantial amounts of heat in using, thus
Also cannot be using the mode of bonding it is necessary to assist fixing mica clamping bar 4 with other parts.Applicant also attempts using steel band bag
The mode on side, in figure does not illustrate, the mode using very thin steel band, mica clamping bar being encased, but this mode is only
Compress mica clamping bar, or the mode of steel band and resistor disc clamping by the pressure of steel band, pressure size is all difficult to meet want
Ask, the vibrations of resistor disc in use easily make steel band come off.And steel band belongs to conductor, resistor can be substantially reduced on the contrary
Creep age distance.Do not reduce creep age distance in the middle of reality and fixing both mica clamping bars difficulty be entirely beautiful together, this mode defect is more,
Not preferred this mode, preferably the first can not reduce creep age distance using the mode of clavuss rivet and also can play fixing work
With.
Finally it should be noted that above example is only in order to illustrating technical scheme, rather than the present invention is protected
The restriction of shield scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
