Abstract
The utility model relates to a resistor, particularly an inductive reactance free nickel-chromium resistor. The utility model is composed of a bracket, one to two ceramic tubes which are arranged on the bracket, and an insulated cushion which is arranged between the ceramic tube and the bracket; the ceramic tube is respectively provided with thread grooves, which are reverse in direction, from the center to the both sides, nickel-chromium wires are wound in the thread grooves, and the midst of the ceramic tube is provided with a parting line frame; the thickness of the insulated cushion is at least 40 mm. When the resistor is provided with two ceramic tubes, the nickel-chromium wires of the two ceramic tubes are connected in series. The utility model solves the problems of large volume, easy rustiness, low voltage resistance and inductive reactance existing in the existing resistors.
Description
The utility model relates to a kind of resistor, particularly the nickel chromium triangle noninductive resistor.
At present, be ZX series resistance device with the resistor of transporting in the intelligent ground compensation pressure limiting device of 6-66KV ZTID series.This resistor adopts the siderochrome aluminum, and it easily gets rusty, volume big, induction reactance is arranged, contact is many, easily open a way, poor reliability.And this resistance in the intelligent ground compensation pressure limiting device of 6-66KVZTID series, use control circuit in the resonance point influence bigger, also it is withstand voltage low.
The purpose of this utility model is to provide a kind of nickel chromium triangle not have the induction reactance resistor, its solved existing resistor volume greatly, easily get rusty, withstand voltage low, problem that induction reactance is arranged.
The purpose of this utility model is achieved through the following technical solutions.Nickel chromium triangle does not have the induction reactance resistor, this resistor by support and be fitted in one to two earthenware on the support and be located at earthenware and support between insulation cushion constitute, earthenware offers reverse each other thread groove from the center respectively to both sides, coiling nichrome wire in the thread groove, the earthenware center is provided with the branch coil holder, and distance is at least 40mm between lead-out tablet on the resistor and the support.When earthenware was made as two in the above-mentioned resistor, two pipes were gone up nichrome wire and are series connection.
After the utility model adopts said structure owing on earthenware, establish positive and negative rib-loop groove, form when making nichrome wire enough become on this pipe coiling just rewind to, constituted noninductive resistor, induction reactance is to the influence of resistor.Be lined with insulating barrier between earthenware and support, distance is at least 40mm between lead-out tablet and the support, makes it withstand voltage and can satisfy circuit requirement, withstand voltage 1-2 ten thousand volts with creepage distance.And having adopted special nichrome resistance wire, its resistivity height, overload are good, make this resistor more a lot of than former resistor volume-diminished.This resistor interface is few in addition, and lead-out wire adopts brazing, reliability height.
In conjunction with the embodiments the utility model is elaborated with accompanying drawing below.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of another embodiment of the utility model.
As shown in Figure 1 is the utility model embodiment one, and this nickel chromium triangle noninductive resistor is by support 1 and be fitted in the earthenware 2 on the support 1 and be located between earthenware 2 and support 1 insulation cushion 3 and constitute.Earthenware 2 offers reverse each other thread groove 4 from the center respectively to both sides, coiling nichrome resistance wire 5 in the thread groove 4, and earthenware 2 centers are provided with branch coil holder 6, and lead-out tablet is 7, and distance is at least 30-40mm between lead-out tablet 7 and the support 1.
As shown in Figure 2 is another embodiment two of the utility model, is provided with two earthenwares 2 on the support 1 of this nickel chromium triangle noninductive resistor side by side.All offer with the center on two earthenwares 2 be the boundary to the reverse each other thread groove 4 in both sides, coiling nichrome resistance wires 5, two pipes are gone up resistive conductor and are series connection in the thread groove 4.
