Working principle:
when the high-voltage resistance of the energy storage wire harness is measured, the high-voltage test wire is pulled out to drive the spring to stretch, the radiator fan is triggered to start, the test clamps on the two sides are respectively clamped on the wire harness, and the display is responsible for displaying readings; when the low-voltage resistance of the energy storage wire harness is measured, the low-voltage test wire is pulled out, the spring is stretched, the test clamps on the two sides are respectively clamped on the wire harness, and the display is responsible for displaying the reading; the heat radiation fan is electrically connected with the internal power supply; the heat dissipation fan dissipates heat inside; after the resistance below the wire harness is measured, the resistance above the wire harness is measured, the wire harness measured by the wire harness above is higher in height, at the moment, the control switch is turned on, and the internal power supply supplies power for the hydraulic rod; the hydraulic rod moves upwards, so that the standing plate is lifted to conveniently measure higher resistance; such that the first high voltage conductor location is replaced by the second high voltage conductor; because the energy storage wire harness is large in volume, more in circuits and longer in measurement time, the first high-voltage conductor is increased in heat quantity after long-time working and is reduced in stability, the second high-voltage conductor is used for replacement work, and the protection device is facilitated; then the rolling curtain moves upwards to provide a rising space for the standing board; the suction plate is made of silica gel, has certain elasticity and is hemispherical with a downward opening; the edge of the suction plate is pulled by the suction plate through the pulling of the first elastic rope and the second elastic rope, the opening is enlarged, and the suction force to the ground is enhanced; the suction plate is pulled down to the ground and is sucked tightly with the ground, so that injury accidents caused by slipping of universal wheels due to unstable gravity center of the device after a user stands on the suction plate are prevented, and the lifting of the suction plate is linked with the fixation of the suction cup and the replacement of the high-voltage conductor, so that the measurement of the resistor with higher position is further facilitated.
Specifically, in the invention, as shown in fig. 3, the problem that the first high-voltage conductor can overheat when measuring the lower high-voltage wire bundle for a long time is solved by linking the replacement of the first high-voltage conductor and the second high-voltage conductor with the upward displacement of the station board, and the high-voltage wire bundle resistance with higher height can be measured immediately, so that the measurement is convenient, the overheat of the internal temperature of the device is prevented, and the protection device is realized.
By raising the standing board, the tension of the elastic rope is larger, the opening of the suction board is larger, and the suction force on the ground is larger, so that the stress of the whole device is balanced when a person stands on the standing board; the technical problem of how to ensure the stability of the device when a user measures the high-area resistance when the standing board rises is solved.
