Compared with the prior art, the resistor has the advantages of simplicity in structure, light weight, small volume, wide application range and the like.
Description
Technical field
The utility model relates to a kind of current-limiting resistor, especially relates to a kind of bushing type electrion loop current-limiting resistor.
Background technology
Current-limiting resistor generally is applied to the high-tension apparatus protective circuit, gives the electrical outdoor discharge capacitor, guarantees continuous 2 discharges fast.Existing pellet resistance, mesh grid resistance, wire resistor, porcelain tube resistance, the small product size that ZnO resistors constant resistance Technology design is produced is too huge, and floor space is big, therefore be inconvenient to install, and cost is high.In addition, for some high power AC resistors, because current-limiting protection is realized by inductance in its inside, can not be applied to direct current system.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple in structure, in light weight, volume is little, widely used bushing type electrion loop current-limiting resistor.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of bushing type electrion loop current-limiting resistor comprises resistance body and insulating barrier, and described resistance body is encapsulated in the insulating barrier, and the two ends of insulating barrier are provided with two leading-out terminals that are connected with the resistance body.
Described resistance body comprises porcelain tube metalfilmresistor and glass reinforced plastic pipe, and described glass reinforced plastic pipe is set in outside the porcelain tube metalfilmresistor, and two leading-out terminals are connected with the two ends of porcelain tube metalfilmresistor respectively.
Described insulating barrier is silicone rubber insulation layer, and this silicone rubber insulation layer is encapsulated in its inside with the sulfuration of resistance body.
The surface of described insulating barrier is provided with a plurality of full skirts along its length, and described full skirt and insulating barrier are one-body molded.
Compared with prior art, the utlity model has following advantage:
(1) compare with other high voltage resistors, high value, high withstand voltage, small size.
(2) compare with the high power AC resistor, inductance is not contained in its inside, can be applicable in interchange and the direct current system.
(3) in light weight, volume is little, is convenient to transportation and on-the-spot the installation.
(4) symmetric design structure is not distinguished end of incoming cables and leading-out terminal, the situation of setup error can not occur.
(5) leading-out terminal both can be used as mounting terminal, can be used as binding post again, and both unite two into one, simple structure.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is Facad structure schematic diagram of the present utility model;
Fig. 3 is side structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As Fig. 1～shown in Figure 3, a kind of bushing type electrion loop current-limiting resistor, comprise resistance body 1 and insulating barrier 2, resistance body 1 is encapsulated in the insulating barrier 2, the two ends of insulating barrier 2 are provided with two leading-out terminals 3 that are connected with resistance body 1, as mounting terminal and the binding post of resistor, namely can strengthen the structural strength of resistor, the lead-out wire that can be used as resistor is arranged.
Insulating barrier 2 adopts silicon rubber, adopts the sulfuration packaging technology that resistance body 1 is encapsulated in its inside, guarantees the insulating properties of resistance, and the surface of insulating barrier 2 is provided with a plurality of full skirts 21 along its length, and this full skirt and insulating barrier are one-body molded, its outer appearnce liny road insulator.
Compare with other high voltage resistors, the utility model uses the porcelain tube metalfilmresistor, high value, and high withstand voltage, small size does not contain inductance in the resistor, go for the AC and DC system, and in light weight, volume is little, is convenient to transportation and on-the-spot the installation.Because two leading-out terminals of resistor all can be used as end of incoming cables or leading-out terminal, the situation of setup error can not occur.
