Technical Field

The invention relates to the technical field of equipment detection, in particular to a function detection device of an electric energy measuring instrument.

Background

In the electric control system, the system calculates the grid-connected power of the converter by measuring current and voltage values through a PLC (programmable logic controller), and the self-power consumption of the control system is not detected. In order to further improve the economic benefit of wind power generation, improve the efficiency of a wind turbine and reduce unnecessary electric energy loss of the wind turbine, the power consumption of each system of the wind turbine needs to be analyzed, and an electric energy measuring instrument is added to measure the self-consumption of the wind turbine, so that a self-consumption database is established, and the generating efficiency of the wind turbine is optimized, so that the performance requirement on the electric energy measuring instrument is strict, and the performance test on the electric energy measuring instrument is particularly important. Because of the difference of parameters such as wiring type, function, degree of accuracy grade of the electric energy measuring instrument, need frequently set up the test circuit and change test condition in the testing process, can greatly reduced the degree of accuracy and the efficiency of test.

The common test has the following defects:

1) the test tool is complicated to build and replace, and the test efficiency is low

During testing, the construction of a test loop needs to be adjusted according to the difference of a wiring mode, an input voltage grade and an input current, and wiring is performed again; when a plurality of electric energy measuring instruments need to be tested simultaneously, the built loops are multiple, errors are easy to occur, and the testing efficiency is low.

2) The test environment condition is single, and the performance of the test environment cannot be fully verified

The performance of the electric energy measuring instrument is influenced by the ambient temperature, the operating temperature of the electric control cabinet is generally-40 ℃ to. +50 ℃, but the electric energy measuring instrument is tested at room temperature, the performance of the electric energy measuring instrument cannot be tested at low temperature, the difference exists between the performance of the electric energy measuring instrument and the environment when the electric energy measuring instrument is used on site, and the tested data has no reference significance;

3) the real-time data of the test is inconvenient to look up, and the judgment on the performance of the test is influenced

In the testing process, testing personnel are required to record testing data in time, and if various electric energy measuring instruments are tested at the same time, a plurality of testing personnel are required to test and record the testing data together, so that errors and deviations are easily generated, and the performance evaluation of the electric energy measuring instruments is influenced.

In summary, in the prior art, the function detection device of the power measuring instrument has the disadvantages of complicated detection and installation procedures, single test environment and inconvenient detection.
