In consideration of portability, the portable tension tester is designed on the aspect of portability, so that the tension tester is more portable.
The technical scheme of the utility model as follows: a tension tester for once inserting of a power distribution drawer comprises a microcomputer and a clamping force probe, wherein the microcomputer is connected with the clamping force probe, the clamping force probe transmits measured clamping force data signals to the microcomputer for data processing and analysis, and measured values are displayed through a display screen connected with the microcomputer.
The microcomputer is connected with a man-machine key, the man-machine key comprises an on/off button, a setting button and an upper, lower, left and right buttons, wherein the on/off button is a multiplexing button, the equipment is powered on after the on/off button is pressed for a short time, the equipment is powered off after the on/off button is pressed for a long time, the setting button is matched with the upper, lower, left and right buttons for use, a display screen of the equipment enters a qualified threshold setting page after the setting button is pressed, and the size of the qualified threshold is adjusted through the matching of the upper, lower, left and right.
The microcomputer is connected with a battery module, the battery module is composed of a polymer lithium battery pack with 5V voltage and 1000mAh capacity, and a working power supply can be provided for the whole tension tester.
The microcomputer is connected with an acousto-optic alarm which can carry out acousto-optic alarm on low electric quantity and unqualified one-time insertion.
The microcomputer adopts an Atmega128 singlechip to carry out logic control on the whole system.
The tensile tester default threshold is greater than 33 Nm.
This tension tester possesses electric quantity self-checking function.
The tension tester has an automatic shutdown function, and if the display screen of the tester changes countless values in more than 5 minutes, the tester is judged to be not used any more and is automatically shut down.
The utility model discloses a show the effect and lie in: a distribution drawer once inserts tension tester, can realize once inserting tensile test to the distribution drawer to carry out audible and visual alarm when the test value is less than the threshold value, with suggestion operating personnel
