Abstract

The invention discloses an automatic safety warning device of a live-line switch bin. The device comprises a busbar, a switch, a switch normally-closed connection point, a switch normally-open connection point and a switch bin body of a load cable wiring terminal and also comprises a detection module, a warning module and a bin door control module, wherein the detection module is used for acquiring voltage signals of the busbar and the load cable wiring terminal, the voltage signals are processed by an analog-digital conversion unit, the warning module is used for displaying the voltage signals and enabling a corresponding indication lamp to be turned on according to a signal of the analog-digital conversion unit and the states of the switch normally-closed connection point and the switchnormally-open connection point, and the bin door control module is used for controlling on / off of a magnetic door lock by a control unit according to signals of an unlocking button and the analog-digital conversion unit. By the device, the defect of safety protection of an existing switch bin is overcome, a warning can be timely reminded during misoperation of maintenance, so that an electric shock accident is prevented, and a potential risk is prevented.

Description

technical field [0001] The invention relates to an automatic safety warning device for a live switch compartment. Background technique [0002] The switch compartment is a commonly used breaking device for supplying power to electric loads such as motors in the power system. When the switch is closed, the load is energized; when the switch is opened, the load is de-energized. Therefore, the performance of the switch compartment directly affects the reliability and safety of the power supply. Therefore, both the switch compartment body and the control, measurement and protection devices of the switch have been continuously improved through research, making the switch compartment increasingly miniaturized, lightweight, intelligent, more convenient to use, and more powerful in function. [0003] However, the safety protection of the live parts of the switch compartment, especially the safety protection of the live busbars and live load cables in the rear door of the switch com...
