[0002] The brake of a hydro-turbine generator set is involved in the protection of the safe and stable operation of the generator set in the power system. The brake design must have efficient braking performance and reliability to ensure that the speed can be quickly reduced in an emergency to prevent equipment damage or accidents, thereby improving overall safety and operating efficiency.

[0003] The hydro-turbine generator set has a complete grounding system. When the brake leaks current, good grounding can introduce the leakage current into the earth to ensure the safety of the staff. Among them, bolt connection is the most common connection method for grounding the motor brake. On the grounding terminal reserved in the metal shell of the brake, the soft copper stranded wire with a copper terminal nose is tightly connected to the grounding terminal through bolts. When connecting, clean the contact surface, place flat washers and spring washers, and tighten the bolts with appropriate torque.

[0004] The ground wire and its terminals are in a complex working environment for a long time and are easily affected by external forces such as vibration and tension, which may cause the ground terminal to loosen and reduce the grounding reliability. Especially for the ground terminal connected by bolts, loose bolts or inappropriate torque may easily lead to poor contact, thus affecting the normal operation of the grounding system.

[0021] Preferably, the right terminal of the ground wire is set on the receiving terminal of the brake body by a bolt.

[0022] Working principle: First, use the fixing screw at the bottom of the brake body to fix it to the mounting shell. Then, install the ground wire on the brake through the hexagonal screw to ensure that it is consistent with the working state. Then start the vibration motor and adjust the vibration frequency of the vibration motor to simulate the vibration of the equipment caused by motor operation, water flow impact, etc. These vibrations will be transmitted to the ground wire and its terminal. After the vibration, observe the condition of the ground wire and its terminal, and then install the other end of the ground wire on the receiving end of the tensile tester. The motor drives the screw rod to move the slider on the slide rail, and then the mounting plate drives the bottom plate to move. In this way, the tensile tester can move in the Y-axis direction. The second motor on the second bottom plate drives the second lead screw to move the second slide block on the second slide rail, so that the tension tester on the second mounting plate is gradually stretched according to the preset distance on the horizontal X-axis. By adjusting the displacement of the X-axis moving mechanism, different degrees of stretching conditions can be simulated, and the performance of the ground wire and its terminal at different stretching distances can be accurately measured, such as observing the changes in related parameters such as the connection firmness of the terminal and the strain of the material during the stretching process, so as to evaluate the ground terminal. The tensile force bearing capacity provides key data support. The travel switch can set the limit travel of the tensile force. When the tensile action of the tensile tester causes the displacement of the grounding terminal to reach the preset limit travel, the travel switch will be triggered to stop the tensile tester from stretching, preventing excessive tensile force from causing excessive stretching, damage or even breakage of the grounding terminal. For example, if the material of the grounding terminal has a certain tensile limit, the travel switch can ensure that the tensile force does not exceed this limit, protect the integrity of the terminal, and control the test range and accuracy. By reasonably setting the trigger position of the travel switch, the range of the tensile test can be controlled. For grounding terminals of different specifications and requirements, the expected tensile force can be set according to their The bearing range is set by the travel switch. During the test, when the travel switch is triggered, it indicates that the tension has reached the preset important test point. The tension and displacement data recorded at this time are critical for evaluating the performance of the terminal, which helps to improve the accuracy and repeatability of the test, so that each test can be carried out within the specified range. In addition, the vibration mechanism and the tension tester can be carried out at the same time, which can truly simulate the actual working environment of the ground wire and its terminal, and test its stability and connection firmness under the joint action of vibration and tension, and evaluate extreme situations, so as to provide data for product optimization design and quality control, and ensure that the ground wire and its terminal are safely and reliably grounded.

[0023] The present invention provides a hydraulic generator set generator brake withstand pressure test device.

[0024] Beneficial effects:

[0025] 1. The present invention simulates the vibration environment in actual working conditions through a vibration mechanism to test the stability and vibration resistance of the ground wire and its terminal under complex dynamic conditions. At the same time, the support mechanism can isolate the impact of vibration on the ground when in use, reduce noise pollution, and the height can be adjusted by turning the nut, creating a more suitable working environment for testing the ground wire and its terminal, and improving the adaptability and flexibility of the test system to testing different ground wires and their terminals.

[0026] 2. The present invention controls the stretching distance between the ground wire and its terminal on the X-axis, simulates stretching conditions of different degrees, and accurately measures parameters such as the connection firmness and material strain of the ground wire and its terminal. The travel switch protects the ground wire, its terminal and the test equipment during the tension test, and is triggered when the displacement of the ground wire and its terminal reaches a preset limit stroke to prevent damage to the ground wire, its terminal and the equipment due to excessive tension. At the same time, the test range and accuracy can be controlled to ensure that each test is carried out within the specified range, thereby improving the accuracy and repeatability of the performance test of the ground wire and its terminal.

[0027] 3.
