Description
Technical field
This utility model is related to electronic devices and components field, specifically a kind of ceramic package high voltage-resistant resistor.
Background technology
The high insulation of ceramic package is pressure, and resistor is used primarily in high-voltage electric power system.Typically require that power is big, high pressure can
By property is good, good stability, resistive dissipation is good.Then common wirewound resistor is being closed due to outer around B alloy wire using porcelain body frame
The structure of high-temperature-resistant insulating paint is coated outside spun gold, but high-temperature-resistant insulating paint is pressure not high, typically also with regard to several hectovolts, and
And resistor using when to also bear the impact of alternating hot and cold for a long time, will be produced using coatings surface after the regular hour
Raw crackle, the insulation for more reducing insulating barrier is pressure.Therefore, common wirewound resistor can not meet power system high pressure height
The requirement of insulation.
Utility model content
The purpose of this utility model is to provide a kind of ceramic package high voltage-resistant resistor, solves Power Resistor in height
The problem of the casing insulation protection under voltage service condition.
The technical solution of the utility model is as follows：
A kind of ceramic package high voltage-resistant resistor, includes ceramic package and porcelain tube, it is characterised in that：Described porcelain tube position

Inserts are filled between pipe and the ceramic package and thermal insulation layer is formed, and are pacified on the outer wall of porcelain tube two end electrodes cap respectively
Equipped with porcelain plug, described porcelain plug is respectively fixedly connected with the two ends of the ceramic package.
Described ceramic package high voltage-resistant resistor, it is characterised in that：The electrode cap composition institute at the porcelain tube and its two ends
State the skeleton of electric resistance alloy silk.
Described ceramic package high voltage-resistant resistor, it is characterised in that：The two ends of the ceramic package and the porcelain plug
Inner side be respectively equipped with the external screw thread and female thread being engaged.
Described ceramic package high voltage-resistant resistor, it is characterised in that：Wave is provided with the middle part of the ceramic package outer wall
The radiating groove of shape.
The beneficial effects of the utility model：
This utility model utilizes high insulation, high withstand voltage and the heat resistance of aluminium oxide ceramics, has reached resistor with the external world
Insulation resistance energy, using the preferable aluminium oxide ceramics of heat conduction and wavy surface, improve heat exchange area, heat transfer effect
More preferably.
Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
Referring to Fig. 1, a kind of ceramic package high voltage-resistant resistor includes ceramic package 3 and porcelain tube 6, and porcelain tube 6 is located at ceramics
The inside of shell 3, the two ends of porcelain tube 6 are separately installed with electrode cap 1, are wound with electric resistance alloy silk 5 on the outer wall of porcelain tube 6, porcelain tube 6 with
Inserts are filled between ceramic package 3 and thermal insulation layer 4 is formed, and are separately installed with the outer wall of 6 two end electrodes cap 1 of porcelain tube
Porcelain plug 2, porcelain plug 2 are respectively fixedly connected with the two ends of ceramic package 3.
In this utility model, the electrode cap 1 at porcelain tube 6 and its two ends constitutes the skeleton of electric resistance alloy silk.
The inner side of the two ends of ceramic package 3 and porcelain plug 2 is respectively equipped with the external screw thread and female thread being engaged, can be tightly
Pinning resistor core.
Wavy radiating groove 7 is provided with the middle part of 3 outer wall of ceramic package.
This utility model is outer around electric resistance alloy silk using porcelain body frame, then together loads porcelain body frame together with electric resistance alloy silk
Thickness fills resistant to elevated temperatures heat conduction exhausted between porcelain body frame and ceramic insulation shell more than in the aluminium oxide ceramics insulation crust of 4mm
Edge inserts, are made electric resistance alloy silk and the external world be separated by Insulation stopping and ceramic package, and it are close to install porcelain plug additional at two ends
Envelope, reaches the pressure requirement of high insulation.As the yield pressure of aluminium oxide ceramics can reach 18kV/mm（The 95% of present manufacturer production
The breakdown voltage of aluminium oxide ceramics is substantially all and can reach more than 30kV-40kV/mm）, therefore, it is of the present utility model pressure non-
Chang Gao, meets the requirement of the high insulation of power industry high voltage.
