The output terminal of the isolation transformer is connected with an automatic controller and can be connected with other to-be-tested loads. The advantages of the device are that the structure is simple and practical; the generated adjustable alternating voltage signal can be connected with a device sample to carry out the device calibration and the functional test; an output loop and an input loop are completely isolated via the isolation transformer, so the personnel safety and the low voltage electric appliance safety are fully guaranteed.

Description

A kind of generation ac voltage signal device
Technical field
The utility model relates to the device that adopts three-phase transtat principle design to produce the scalable alternating voltage.
Background technology
The line voltage of electrical equipment detects at present; Can only judge whether voltage is normal through section breaker; The civil power that can not effectively simulate line voltage decline or rise when exceeding normal operating range is failed; Often when the equipment debugging performance, self-actuated controller can occur and break down, and can only when equipment work, could find, this just wastes resource and the work difficulty that increases the commissioning staff to a great extent.
Summary of the invention
The utility model provides a kind of generation ac voltage signal device; It is the device of the generation AC signal a kind of simple in structure and practical that designs in order to solve above-mentioned staff's debug difficulties, can be connected in the sampling of equipment and goes to carry out Equipment Alignment and functional test producing the scalable ac voltage signal.
The technical scheme that the utility model adopts is to comprise three-phase alternating-current supply, three-phase transtat, isolating transformer and self-actuated controller; The utility model particularly three-phase alternating-current supply is connected with the input end of three-phase transtat; The output terminal of three-phase transtat is connected to the input end of isolating transformer; The output terminal of isolating transformer is connected to self-actuated controller, also can be connected to other loads to be tested.
The input and output turn ratio of the iron core that isolating transformer adopts is 100:10, incoming line footpath: 0.6mm, output line footpath: 1mm.
The principle of work of the utility model is to exchange the input of 380V power supply; Through regulating the output voltage of three-phase transtat; The former limit of isolating transformer flows into alternating voltage, in iron core, produces the magnetic flux of alternation, induction electromotive force of secondary output; Secondary is connected to self-actuated controller forms a closed-loop path, promptly produce loop voltage.The former limit input voltage of regulating isolating transformer through the three-phase transtat can obtain corresponding secondary output voltage, and the size that scalable like this obtains output voltage is that 0-450V uses to satisfy equipment debugging and calibrating indicating instrument.
The utility model has the advantages that the device of generation AC signal simple in structure and practical; Can be connected in the sampling of equipment and go to carry out Equipment Alignment and functional test producing the scalable ac voltage signal; And output loop and input circuit isolate through isolating transformation fully, fully guaranteed the safety that the person and low-voltage electrical apparatus use.
