Description

Technical Field

[0001] This utility model relates to the technical field of generator testing devices, specifically a high-power mud turbine generator testing device. Background Technology

[0002] A high-power mud turbine generator is a device that uses downhole mud circulation to drive a turbine to rotate, converting mechanical energy into electrical energy. It is mainly used for power supply of drilling systems. When the generator is being tested for performance, a special generator testing device is required to assist in the operation.

[0003] For example, announcement number CN206209076U (titled "A Turbine Generator Testing Device") includes a testing platform. On the top of the testing platform are mounted a generator rotor support, a speed measuring disc, a power switch, a speed control knob, a generator test terminal, a tachometer, a voltmeter, and an ammeter. The tachometer, voltmeter, and ammeter are electrically connected to the generator test terminal. At the bottom of the testing platform are mounted a DC speed-regulating motor and a control box. The control box is electrically connected to the DC speed-regulating motor, and the power switch, speed measuring disc, and speed control knob are electrically connected to the control box. A generator rotor is supported on the generator rotor support. The generator rotor is connected to the output shaft of the DC speed-regulating motor via a large and small pulley assembly. No actual testing in a fluid environment is required. The DC speed-regulating motor drives the generator rotor to rotate, simulating rotor rotation driven by a fluid. The speed of the DC speed-regulating motor is adjustable, and the change in speed simulates the scouring effect of different fluid flow velocities on the generator rotor. Power generation is achieved simply by connecting a magnet assembly to the end of the generator rotor and setting up a corresponding set of magnetic induction coils. Testing is convenient. The entire structure requires only a DC speed-regulating motor and pulley assembly to drive the generator rotor, making it simple and easy to operate.

[0004] The aforementioned turbine generator testing device lacks an effective clamping mechanism during the generator testing process, resulting in poor generator stability and affecting the accuracy of generator testing. Therefore, we provide a high-power mud turbine generator testing device. Utility Model Content
