The testing device comprises a generator output analogue circuit, a voltage regulator output checking circuit and a test power supply circuit, wherein the test power supply circuit is respectively connected with the generator output analogue circuit and the voltage regulator output checking circuit, and the generator output analogue circuit and the voltage regulator output checking circuit are connected with a voltage regulator through cables. In the utility model, the generator output analogue circuit and the voltage regulator output checking circuit are adopted to simulate the normal generating state, the starting state and the fault state of a starter generator and to replace the starter generator to conduct coordinative tests with the voltage regulator, and the test device is adopted to replace a drive motor and the starter generator, so that the tests of regulation function (voltage regulation in the generating state and current regulation in the starting state), control function and protection function of the voltage regulator in the open-loop state can be achieved, thereby lowering the test cost, reducing the required testing field, and relieving the labor intensity for operators.
Description
Technical field
The utility model belongs to detection technique, relates to a kind of pressure regulator open loop test unit that is used to detect the aircraft pressure regulator.
Background technology
The aircraft pressure regulator is matching used with starter-generator, and its major function is at generating state regulator generator output voltage, shields at starting state regulator generator armature supply and when the aircraft electrical network breaks down.Pressure regulator is when testing, and the project that needs to check has: the generator voltage regulatory function checks that starting current keeps functional check and generator failure protection and reset function inspection.
The test method of existing pressure regulator is the closed test method, uses promptly that starter-generator and pressure regulator are supporting to be tested.When testing, needing to use dragging motor to drag starter-generator makes it be operated in the nominal operation state, reexamine data such as the output voltage, exciting curent of generator this moment, check and generator failure protection and reset function inspection with the generator voltage regulatory function that realizes pressure regulator; Use the moment testing table to apply rated moment starts the generator of pressure regulator with realization electric current maintenance functional check to starter-generator.
The shortcoming of this closed test method is must use dragging motor and starter-generator when testing, so the experimentation cost height, and required place is big, and operator's labour intensity is also bigger when testing.
Summary of the invention
The purpose of this utility model is that a kind of experimentation cost of proposition is low, the pressure regulator open loop test unit that required place is little.Technical solution of the present utility model is, test unit comprises generator output mimic channel, pressure regulator outgoing inspection circuit and test feed circuit, the test feed circuit join with generator output mimic channel and pressure regulator outgoing inspection circuit respectively, and output mimic channel and pressure regulator outgoing inspection circuit join by cable and pressure regulator.Advantage that the utlity model has and beneficial effect; the utility model adopts the normal power generation state of generator output mimic channel and pressure regulator outgoing inspection breadboardin starter-generator; starting state and malfunction; substitute starter-generator and pressure regulator and carry out coordinative experiments; substitute dragging motor and starter-generator with test unit; realized under open loop situations, pressure regulator being carried out regulatory function (generating state regulation voltage; starting state is regulated electric current); the test of control function and defencive function; reduced experimentation cost; reduce the required place of test, alleviated operator's labour intensity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.Test unit 2 comprises generator output mimic channel 3, pressure regulator outgoing inspection circuit 4 and test feed circuit 5, test feed circuit 5 join with output mimic channel 3 and pressure regulator outgoing inspection circuit 4 respectively, and output mimic channel 3 and pressure regulator outgoing inspection circuit 4 join by cable 6 and pressure regulator 1.
Test unit also should comprise power circuit and pressure regulator outgoing inspection circuit, for test unit power supply and check pressure regulator for the laboratory technician whether function is normal.
