Description
Technical field
The utility model relates to a kind of aluminum-housed resistor, is applicable to high voltage environment, belongs to resistor field.
Background technology
Existing conventional aluminum casing resistor be by resistance wire on porcelain tube, then put it into and be filled with in magnesian aluminum hull, it is withstand voltage can only reach about 4000V, cannot meet the requirement of high voltage (8000V left and right).And traditional aluminum-housed resistor weak heat-dissipating, when high voltage occasion is used, need to adopt the device of additional bulky dielectric mode, to improve voltage withstand class, its complex structure, install loaded down with trivial details, dangerous high.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of voltage withstand class aluminum-housed resistor high, simple in structure, easy for installation, solved traditional aluminum-housed resistor when high voltage occasion is used, adopt supplementary insulation mode, thereby cause loaded down with trivial details, the dangerous high problem of its installation.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of aluminum-housed resistor, it is characterized in that, comprise electrothermal tube, in electrothermal tube, be provided with resistance wire and magnesium oxide packed layer, electrothermal tube is located in the die cavity of aluminum hull, between electrothermal tube and aluminum hull, is filled with magnesium oxide, the two ends, left and right of aluminum hull are respectively equipped with backboard and front apron, and one end of electrothermal tube is provided with the binding post through front apron.
A kind of manufacture method of aluminum-housed resistor, it is characterized in that, comprise the following steps: resistance wire is put into stainless steel tube, fill after magnesium oxide, shrink caliber, make it be configured as electrothermal tube resistance, then put it in the cavity die cavity of aluminum hull, again fill magnesium oxide, by its compacting, two ends form aluminum-housed resistor after sealing by backboard and front apron.
The utility model has been cancelled original porcelain tube that is wound with resistance wire, changed into the electrothermal tube that is embedded with resistance wire, the characteristic of utilizing electrothermal tube itself to shrink, electrothermal tube is combined with aluminum hull, make electric clearance and creepage distance have corresponding increase, due to magnesian tight filling, resistive element is sealed in magnesium oxide, both guaranteed the increase of resistance hot melt, guaranteed again the distance of insulation, improved withstand voltage grade, and it is simple in structure, easy for installation, dangerous low, its applied range.
Accompanying drawing explanation
Fig. 1 is a kind of overall structure schematic diagram of aluminum-housed resistor;
Fig. 2 is a kind of internal structure schematic diagram of aluminum-housed resistor.
Wherein: 1 is binding post, 2 is aluminum hull, and 3 is electrothermal tube, and 4 is die cavity, and 5 is backboard, and 6 is front apron.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
A kind of aluminum-housed resistor, as shown in Figure 1 and Figure 2, it comprises electrothermal tube 3, in electrothermal tube 3, there are resistance wire and magnesium oxide packed layer, electrothermal tube 3 is arranged in the die cavity 4 of aluminum hull 2, between electrothermal tube 3 and aluminum hull 2, be filled with magnesium oxide, the two ends, left and right of aluminum hull 2 are separately installed with backboard 5 and front apron 6, and one end of electrothermal tube 3 is provided with the binding post 1 through front apron 6.By by 1 liang of terminated line of binding post in circuit, can use.
The manufacture method of aluminum-housed resistor is: resistance wire is put into a stainless steel tube, fill after magnesium oxide, shrink caliber, make it be configured as electrothermal tube resistance, then put it in aluminum hull cavity, again fill magnesium oxide, by its compacting, after sealing two ends, form new resistor.
Aluminum-housed resistor of the present utility model is to have carried out internal modifications on former traditional aluminum-housed resistor basis, and its profile, installation dimension and use effect are the same with traditional aluminum-housed resistor.But the proof voltage of a kind of aluminum-housed resistor of the present utility model is significantly increased, by original 4000V, be increased to 10000V, its range of application is greatly expanded.
Because traditional aluminum-housed resistor is when high voltage occasion is used, need to adopt supplementary insulation mode, to improve voltage withstand class, complexity is installed, and dangerous high.And adopting resistor of the present utility model this product directly can be applied and any system below 10000V, structure is greatly simple.
