The fixed groove or fixation hole is the surface that integral hollow ceramic insulation pipe end is arranged in, and is one or two
Head setting fixed groove or fixation hole；The quantity of fixed groove or fixation hole is 1-3, is uniformly arranged.
Above-mentioned listed embodiment, only carries out clear, complete description to technical solution of the present invention in conjunction with attached drawing；It is aobvious
So, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, all other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
Description through the foregoing embodiment, it is known that the invention further relates to a kind of for the whole exhausted of chip resistor
The application of edge pipe, integral insulation pipe can be widely applied in various chip resistors between the resistance band or resistor disc of resistance unit
Isolated insulation and positioning, as shown in Fig. 13, isolated insulation and positioning use between the resistance band or resistor disc 404 of resistance unit
Whole insulation tube 401 carries out isolated insulation and positioning between resistance band or resistor disc.
Further, the integral insulation pipe is used in the chip braking resistor of electric locomotive, for resistance unit
Isolated insulation and positioning between resistance band or resistor disc.
The present invention has the advantages that
The present invention changes into the existing mode for carrying out isolated insulation to resistance band or resistor disc with porcelain piece or insulator respectively
Resistance band or resistor disc are dielectrically separated from using integral insulation pipe, the mode of isolation is not only simplified, also improves electricity
The integral insulation performance of unit is hindered, effectively there are be easy in rain spraying environment for the isolated insulation between solution resistance band or resistor disc
The problem of existing creepage distance shortens, effectively improves insulation performance of the resistance unit in rain spraying environment, meet resistance unit
High pressure resistant requirement in rain spraying environment.
By using integral insulation pipe, completely eliminate between original porcelain piece and resistance band and between porcelain piece and porcelain piece
Gap so that being not in since rain spraying environment makes between porcelain piece and resistance band and porcelain between resistance band and support rod
Gap infiltration between part and porcelain piece, leads to conduction, so that the creepage distance between resistance band and support rod is substantially reduced
The phenomenon that occur, test proves that the pressure-resistant performance using integral insulation pipe will not be influenced by rain spraying environment again, Er Qienai
Pressure performance has large increase, is as follows: with traditional porcelain piece isolation method contrast test effect
| Serial number | Title | Pressure voltage under drying condition | Pressure voltage under the conditions of drenching with rain |
| 1 | Insulate pipe unit | 20000 VAC | 7000 VAC |
| 2 | Conventional elements | 12000 VAC | 3000 VAC |
By above-mentioned test result it is clear that improved pressure resistance performance is improved significantly, height can satisfy completely
The performance requirement of the various environment such as iron, motor-car.
