A device for measuring electrical variables of mining machinery motors

Abstract

The invention provides a device for measuring electrical variables of mining machinery motors, which relates to the technical field of electrical variable measurement. , the bottom of the top plate is fixedly provided with two groups of pressing blocks, and the front side corners of the bottom of the pressing blocks are rounded structures; the air control device is fixedly arranged on the right end of the rear side of the rear plate; the air control device includes a lead screw The top of the air control device is fixedly provided with a lead screw frame, and the middle of the lead screw frame is rotatably provided with a lifting screw; the gas control device of each embodiment of the present invention can adjust the air pressure measurement variable, and rotate the lifting screw to drive the square piston to rise and fall To adjust the internal air pressure of the housing by air control, that is, to measure the electrical variables of the motor when the air pressure is affected. The technical solution of the present invention is used to solve the problem that it is difficult for the currently used measuring device to simultaneously measure a plurality of factors that cause changes in the power consumption of the motor.

Description

technical field [0001] The invention relates to the technical field of electrical variable measurement, in particular to a device for measuring electrical variables of a mining machinery motor. Background technique [0002] The working principle of the motor is that the energized coil is forced to rotate in the magnetic field to drive the rotor of the starter to rotate. When using it in a mine, it is necessary to consider the temperature of the motor, the air pressure change of the working place, the magnetic field interference of the place of use and the influence of the load degree on the motor. The aforementioned influencing factors may cause changes in the power consumption of the motor. [0003] However, the currently used measuring devices are difficult to measure the above problems at the same time, do not have the function of directly adjusting the air pressure to measure electrical variables, do not have the function of adjusting the magnetic field to interfere with...

Problems solved by technology

[0003] However, the measuring devices currently used are difficult to measure the above problems at the same time. They do not have the function of directly adjusting the air pressure to measure electrical variables, do not have the function of adjusting the magnetic field to interfere with the operation of the motor to measure electrical variables, and do not have the ability to flexibly test different loads to achieve electrical variables.
