Power system secondary small line wiring strength test tool

Abstract

The invention discloses a power system secondary small wire wiring strength testing tool. The tool comprises a spring elastic piece and a handle, and the spring elastic piece is provided with a clamping part for clamping the secondary small wire; the handle is internally connected to a tension sensor of the spring elastic piece and a single chip microcomputer connected to the tension sensor, and the single chip microcomputer is connected with a buzzer and an alarm lamp; the single chip microcomputer compares a tension force value measured by the tension sensor with a tension force threshold, when the tension force value measured by the tension sensor is greater than the tension force threshold, the alarm lamp is blinked, and the buzzer sends out warning tone. The system has the advantagesof being capable of achieving the standardization of the secondary small line wiring strength test, overcoming the difference of the magnitude of individual force, preventing the case that the wiringwhich does not meet the requirements is not detected due to too small force, and preventing excessive force from causing the misjudgment that the wiring does not meet the requirements.

Description

technical field [0001] The invention relates to a tool for testing the connection strength of secondary small wires in a power system. Background technique [0002] In recent years, with the rapid development of the real estate industry, a large number of newly built residential quarters and commercial centers will be completed every year, and the supporting distribution substations will also be put into use accordingly. From design, construction to operation, the construction time of new substations Short, the degree of automation is high, and the quality of construction directly affects the stability and safety of power supply. In order to ensure the safe operation of the substation, each substation has tens of thousands of secondary small wires used for remote control, telemetry, remote signaling or communication to connect to the relay protection equipment and the substation monitoring system. The wiring of these secondary small wires The quality will directly affect th...
