Affiliated technical field
The utility model belongs to power-supply device test load resistive technologies field, is specifically related to a kind of high-power liquid ohmic load device, is applicable to high-power generator or high-power power supply kind equipment electric performance test.
Background technology
As everyone knows, when being carried out electric performance test, high-power generator or other high-power power supply kind equipments need provide fictitious load.At present, the form of fictitious load mainly contains two kinds: a kind of fictitious load that is to use solid resistor and so on, this fictitious load is because the restriction of radiating mode, power is generally less, and general employing of this type of load equipment has level to regulate, therefore, incompatibility high-power generator or the requirement of high-power power supply kind equipment electric performance test; Another kind is to adopt transformer that high pressure is become low pressure, uses low hydraulic fluid ohmic load to test at low pressure end, this load rapid heat dissipation, and power can be accomplished very big, but owing to need the additional configuration transformer, cost of investment is higher.At present, need seek a kind of high-power load device simple and reliable, with low cost, to satisfy the electric performance test needs of high-power generator or high-power power supply kind equipment.
Summary of the invention
The purpose of this utility model is exactly in the past when high-power generator or other high-power power supply kind equipments carry out electric performance test, the problem and shortage part that the fictitious load that is provided exists, and a kind of high-power liquid ohmic load device simple and reliable, with low cost is provided.
Technical solution of the present utility model is: a kind of high-power liquid ohmic load device, comprise the liquid resistance box, the moving electrode plate, the fixed electrode plate, position transducer, dragging motor, drive lead screw, slide block, controller, the moving electrode plate is connected with drive lead screw by slide block, position transducer is installed on the slide block, drive lead screw is connected with dragging motor by gear, controller and dragging motor, position transducer is connected by electric wire, its principal character is: the moving electrode plate, all insert in the interior resistor fluid of liquid resistance box the lower end of fixed electrode plate, the fixed installation of fixed electrode plate, but moving electrode plate move left and right.
Liquid resistance box described in the technical solution of the present utility model is the casing of open topped, and memory box has resistor fluid.The fixing assembling of one end of resistor fluid case fixed electrode plate, the other end is provided with the moving electrode plate, and drive lead screw, slide block are installed at an upper portion thereof.
Fixed electrode plate described in the technical solution of the present utility model is a metal material, is fixed on a end in the resistor fluid case by insulating material, and insert in the resistor fluid in the resistor fluid case lower end of fixed electrode plate.
Moving electrode plate described in the technical solution of the present utility model is a metal material, be installed on the slide block by insulating material, insert in the resistor fluid lower end, and the slide block move left and right can change the distance between moving electrode plate and the fixed electrode plate, thus change move, the resistance value between the fixed electrode plate.
Drive lead screw described in the technical solution of the present utility model is a metal material, is connected with dragging motor by gear, and drive lead screw drives by dragging motor and rotates, thereby drives suit slide block move left and right thereon.
Position transducer described in the technical solution of the present utility model is one moving electrode Board position variable can be converted to the device of electric signal, and its effect is to be moving electrode Board position signal transition that electric signal is delivered to controller.
Controller described in the technical solution of the present utility model links to each other with position transducer with dragging motor by electric wire, according to the signal of position transducer with data are set compare the rotary state of control dragging motor.
The beneficial effects of the utility model are: adopt simple gear train, under the control of position transducer and controller, change the distance of moving electrode plate and fixed electrode plate, variation by moving electrode plate and fixed electrode plate distance, regulate the resistance of liquid resistance easily, satisfy the needs that high-power generator or other high-power power supply kind equipments carry out electric performance test, both improved the continuity that high-power generator or other high-power power supply kind equipments carry out electric performance test, homogeneity, reliability, the while has been reduced the cost of investment of high-power generator or the employed pull-up resistor device of high-power power supply kind equipment electric performance test again.
Below in conjunction with accompanying drawing the utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, controller; 2, position transducer; 3, moving electrode plate; 4, drive lead screw; 5, fixed electrode plate; 6, liquid resistance box; 7, dragging motor; 8, slide block.
Embodiment
As shown in Figure 1, controller (1) control dragging motor (7) rotates, and dragging motor (7) drives drive lead screw (4) and rotates, and drive lead screw (4) is by the screw thread transmission, drive slide block (8) move left and right, make moving electrode plate (3) move left and right in the liquid resistance box (6).Controller (1) by position transducer (2) signal and setting value relatively after, judge whether moving electrode plate (3) position suitable.When deflection fixed electrode plate (5) direction of moving electrode plate (3) position, controller (1) control dragging motor (7) is rotated in the forward, and makes moving electrode plate (3) to moving away from fixed electrode plate (5) direction; When moving electrode plate (3) position was partial to away from fixed electrode plate (5) direction, the reverse rotation of controller (1) control dragging motor (7) made moving electrode plate (3) to moving near fixed electrode plate (5) direction; Stop to move after moving electrode plate (3) position reaches setting value, it is stable that the spacing between moving electrode plate (3) and the fixed electrode plate (5) keeps.Device is by changing the spacing between moving electrode plate (3) and the fixed electrode plate (5), change moving electrode plate (3), fixed electrode plate (5) two interelectrode resistance values satisfy the high-power generator or other high-power power supply kind equipments carry out the requirement of electric performance test.
