Abstract
The invention relates to a sleeve type high-voltage discharge circuit current-limiting resistor. The resistor comprises a resistor body and an insulation layer, wherein the resistor body is encapsulated in the insulation layer; and two leading-out terminals are arranged on the two ends of the insulation layer and are connected with the resistor body. 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 present invention relates to a kind of current-limiting resistor, especially relate to a kind of bushing type resistor for electrion loop.
Background technology
Current-limiting resistor is generally applied to high-tension apparatus protective circuit, gives electrical outdoor discharge capacitor, guarantees continuous 2 electric 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 large, be therefore 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.
Summary of the invention
Object of the present invention be exactly provide in order to overcome the defect that above-mentioned prior art exists a kind of simple in structure, lightweight, volume is little, the widely used bushing type resistor for electrion loop.
Object of the present invention can be achieved through the following technical solutions:
For the bushing type resistor in electrion loop, comprise resistance body and insulating barrier, described resistance body is encapsulated in insulating barrier, and the two ends of insulating barrier are provided with two leading-out terminals that are connected with resistance body.
Described resistance body comprises porcelain tube metalfilmresistor and glass reinforced plastic pipe, and described glass reinforced plastic pipe is set in outside 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 by resistance body sulfuration encapsulation therein.
The surface of described insulating barrier is provided with multiple full skirts along its length, and described full skirt and insulating barrier are one-body molded.
Compared with prior art, the present invention has the following advantages:
(1) compared with other high voltage resistors, high value, high withstand voltage, small size.
(2) compared with high power AC resistor, inductance is not contained in its inside, can be applicable in interchange and direct current system.
(3) lightweight, volume is little, is convenient to transport and on-the-spot installation.
(4) symmetric design structure, does not distinguish end of incoming cables and leading-out terminal, there will not be the situation of setup error.
(5) leading-out terminal both can be used as mounting terminal, can be used as again binding post, and both unite two into one, simple structure.
Brief description of the drawings
Fig. 1 is perspective view of the present invention;
Fig. 2 is Facad structure schematic diagram of the present invention;
Fig. 3 is side structure schematic diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in FIG. 1 to 3, a kind of bushing type resistor for electrion loop, comprise resistance body 1 and insulating barrier 2, resistance body 1 is encapsulated in 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, can strengthen the structural strength of resistor, there is the lead-out wire that can be used as resistor.
Insulating barrier 2 adopts silicon rubber, adopts sulfuration packaging technology that resistance body 1 is encapsulated therein, ensures the insulating properties of resistance, and the surface of insulating barrier 2 is provided with multiple full skirts 21 along its length, and this full skirt and insulating barrier are one-body molded, and its outer appearnce is like line insulator.
Compared with other high voltage resistors, the present invention uses porcelain tube metalfilmresistor, and high value is high withstand voltage, and small size not containing inductance, goes for AC and DC system in resistor, and lightweight, volume is little, is convenient to transport and on-the-spot installation.Because two leading-out terminals of resistor all can be used as end of incoming cables or leading-out terminal, there will not be the situation of setup error.
