Description
Technical field:
The utility model relates to the electronic component technology field, refers in particular to a kind of steel pipe cement resistor that is applicable in the power-supply system burn-in test.
Background technology:
In power-supply system (AC/DC POWER SYSTER) field, demand load carries out burn-in test to power-supply system, existing load product is mainly cement resistor, load resistance can generate heat and produce high temperature during owing to energized, therefore when the large power supply system testing, existing this class cement resistor has the following disadvantages: (1) overload capacity is limited, and impulse current is excessive very easily to burn inefficacy; (2) radiating effect is not good, non-refractory; (3) insulation is not enough, can't use for a long time at hot and humid environment.Therefore have much room for improvement.
The utility model content:
The purpose of this utility model is to provide a kind of steel pipe cement resistor at the above-mentioned weak point of existing cement resistor device.
The utility model realizes that the technical scheme that its purpose adopts is: a kind of steel pipe cement resistor, comprise at least one group of resistive element and lead-in wire thereof, described resistive element places in the steel pipe, lead-in wire is piercing in described steel pipe, the periphery, two ends of described resistive element is arranged with high temperature resistant cushion rubber respectively, and described resistive element, high temperature resistant cushion rubber are encapsulated in the described steel pipe by cement slurry.
Described resistive element is to be formed by connecting by several resistors, and each junction is equipped with lead-in wire.
Described lead-in wire is high temperature resistant lead-in wire.
After the utility model adopted technique scheme, the sealing of steel pipe cement resistor, insulating properties and resistance to elevated temperatures were increased dramatically, and can be used for the load of hot and humid environment, and can bear bigger rush of current.In addition, therefore the utility model also can use very convenient as required by changing the resistance that the lead-in wire that connects changes resistance output.
Description of drawings:
Fig. 1 is the structural representation of the noninductive cement resistor device of the utility model.
Embodiment:
As shown in Figure 1, steel pipe cement resistor described in the utility model comprises at least one group of resistive element 1 and goes between 2, resistive element 1 is to be formed by two resistors, 11 serial connections in the present embodiment, and also is provided with lead-in wire 2 in its junction, and described lead-in wire 2 is high temperature resistant lead-in wire. Described resistive element 1 integral body places in the steel pipe 3, article three, lead-in wire 2 all is piercing in described steel pipe 3, the periphery, two ends of described resistive element 1 is arranged with high temperature resistant cushion rubber 4 respectively, and described resistive element 1, high temperature resistant cushion rubber 4 are encapsulated in the described steel pipe 3 by cement slurry 5.With resistive element 1 and 3 built on stilts isolation of steel pipe, avoid resistive element 1 directly to contact by high temperature resistant cushion rubber 4, make the space that has filling concrete slurry 5 required between resistive element 1 and the steel pipe 3 with steel pipe 3.
In use, can be as required by changing the resistance that the lead-in wire 2 that connects changes resistance output, for example with lead-in wire 2 places in circuit at two ends, promptly two resistors 11 are connected, and then exporting resistance is the 11 resistance additions of two resistors; Three lead-in wires are all connected for another example, and then two resistors 11 form parallel connection, and therefore the resistance the when resistance of its output also becomes parallel connection use very convenient.
After the utility model adopted technique scheme, the sealing of steel pipe cement resistor, insulating properties and resistance to elevated temperatures were increased dramatically, and can be used for the load of hot and humid environment, and can bear bigger rush of current.
