Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage test machine, in particular to a box-type outer cover of a high-voltage test machine. Background Art

[0002] Motor type test is an important motor operation and safety performance test. It is a method to check the characteristics of the motor under various operating conditions to determine whether it meets the technical and quality requirements. It mainly detects the motor's power, efficiency, temperature, load, acceleration, under-excitation and other parameters to determine the motor's operating performance.

[0003] Motor type tests usually use a test machine, which drives the tested machine to run and detects various parameters of the tested machine through various detection sensors. For safety reasons, the test machine is mostly placed in a protective cover during motor type tests. Since high-voltage motor type tests take a long time, the temperature around the test machine will be very high when the test machine works for a long time, which is particularly serious in summer. Therefore, it is necessary to dissipate heat and cool the environment of the test machine and the protective cover. The commonly used method is to install shutter fans on the side walls of the protective cover to cool down. However, in actual application, it is found that the shutter fans are not very effective. The ventilation effect of the blade fan is limited, and it is difficult to achieve an ideal heat dissipation effect; in addition, since the test machine and the accompanying test machine work close to each other, the heat emitted by the accompanying test machine on the side close to the test machine will also enter the test machine, thereby affecting the temperature rise test results of the test machine and causing deviations in the experimental data; in addition, due to the limitation of the site space, the protective cover is generally not designed to be too large, and the space between the protective cover and the accompanying test machine is relatively small. When repairing and maintaining the accompanying test machine, working in the narrow space inside the protective cover is not conducive to the physical and mental health of the staff, and at the same time, it also affects the staff's work efficiency.
