The comprehensive experimental system of power automation and relay protection is a highly automated multi -functional test platform. It can use teaching experiments to open multiple electrical engineering courses. Multiple sets of tr--ning systems can also form a complex power network system for comprehensive experiments. The tr--ning, which is a comprehensive monitoring of the power network by the power automation monitoring system, can also form any digital intelligent substation structure.

The device entrance is equipped with a leakage protector.

The entire experimental system control power supply (including relay auxiliary voltage) uses a DC 24V power supply within a safe voltage. The experimental signal requirements are required to output in accordance with the second standard of the power system, and the output power is strictly controlled to prevent hidden dangers of electric shock.

1. Function and characteristics:

The bolt group connects the experimental device to perform experiments such as bolt static stress, deformation, stiffness, axial load, pre -tightening tightening, and other experiments.

Special test analysis software can perform related detection of bolt static and dynamic, and can compare the measured and simulation curve, and the curve can be printed.

All tested elements adopt a full bridge test circuit, and each str--n testing structure is stable, repetitive, and high accuracy.

A single -phase AC motor (220V power supply) is used to start the motor for a dynamic bolt experiment.

Dedicated test analysis software has multimedia teaching functions. Students can expl--n the experiments by experiments in the software and edit the test report through the software.

2. Experimental purpose

1. Understand the stress situation of the bolt connection during the tightening process.

2. Calculate the relative rigidity of the bolt and draw the stress deformation diagram of the bolt connection.

3. When verifying the load of the axial direction, the deformed rule of the pre -tightening bolt is connected, and the impact on the total pull force of the bolt.

4. Through the dynamic carrier experiment of the bolt, change the relative stiffness of the bolt connection, observe the changes in the amplitude of the bolt, to verify the measures that increase the intensity of the bolt connection.

3. Experimental project

1. Basic bolts connect to quiet dynamic experiments.

2. Increase the static and dynamic experiments of the bolt rigidity.

3. Increase the static and dynamic experiments of the rigidity of the connection.

4. Use the static and dynamic experiment of elastic pads.
