Abstract

The invention discloses a unit efficiency tester. The unit efficiency tester comprises a wiring board, a signal conditioning board, a power transmitter, a frequency transmitter and a power module, wherein the wiring board, the signal conditioning board, the power transmitter, the frequency transmitter and the power module are mutually and electrically connected. The unit efficiency tester is characterized by further comprising a data collecting module electrically connected with the components, and the data collecting module is connected with a testing computer through a serial port and communicates with the testing computer. As the data collecting module is arranged, on one hand, the capacity for collecting and managing testing data is improved, on the other hand, the data collecting module can be connected with the computer and used for data transmission, and compared with a testing instrument in the past, the unit efficiency tester is more convenient to use.

Description

A unit efficiency tester

technical field

The invention relates to an instrument for testing the performance of a hydroelectric generator set in a hydropower station, in particular to a unit efficiency tester.

Background technique

At present, most of the instruments used for efficiency testing of hydropower stations and hydroelectric generating units are relatively simple in performance. For example, they cannot connect to the Internet and can only display the data of a single test, which makes it inconvenient to use in the actual test process.

Contents of the invention

The present invention aims at the above problems and proposes a unit efficiency tester that is easy to use and can be connected to the Internet.

In order to achieve the above-mentioned technical purpose, the present invention adopts a unit efficiency tester, which includes a wiring board, a signal conditioning board, a power transmitter, a frequency transmitter and a power module electrically connected to each other, and is characterized in that it also includes A data acquisition module electrically connected to the above components, the data acquisition module is connected and communicated with the test computer through a serial port.

By setting the data acquisition module, the present invention increases the ability of test data collection and management on the one hand, and can be connected to a computer for data transmission on the other hand, which is more convenient to use than the previous test instruments.

Description of drawings

Shown in Fig. 1 is the appearance structure drawing of the present invention;

Among them, 1. Wiring board; 2. Signal conditioning board; 3. Power transmitter; 4. Frequency transmitter; 5. Power module; 6. Data acquisition module; 7. Serial port; 8. Test computer.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

It can be seen from Fig. 1 that a unit efficiency tester includes a wiring board 1 electrically connected to each other, a signal conditioning board 2, a power transmitter 3, a frequency transmitter 4 and a power module 5, and also includes one and the above-mentioned The data collection module 6 that parts are connected electrically, this data collection module 6 is connected and communicated with test computer 8 through serial port 7; Computer connection is used for data transmission, which is more convenient to use than previous test instruments.
