Abstract

The invention discloses an electricity-approaching alarm drum comprising a main control chip and a buzzer SPK1. The main control chip is provided with an LED Key interface, a Test Key interface, an AN1 interface, an AN2 interface, an Ac DetON interface, an Ac DET interface, a Det 1kV interface, a Det 10kV interface, and a Det 110kV interface. The LED Key interface is grounded through a key K1, and the Test Key interface is grounded through a key K2. The AN1 interface is connected with the negative electrode of the buzzer SPK1 through a resistor. The AN2 interface is connected with the gate of an NMOS tube Q1 through a resistor. The drain of the NMOS tube Q1 and the positive electrode of the buzzer SPK1 are connected with a power end of a battery. The source of the NMOS tube Q1 is connected with an LED constant-voltage circuit. The Det 1kV interface, the Det 10kV interface and the Det 110kV interface are respectively connected with a grounded LED lamp through a resistor. The Ac DetON interface is connected with a booster circuit. The Ac Det interface is connected with a signal amplifying circuit.

Description

technical field [0001] The invention relates to a near-electrical warning cylinder in the field of electric power maintenance. Background technique [0002] With the in-depth development of microcomputer monitoring in power systems, the integrated automation technology of substations is more and more used in substations. Substation integrated automation creates favorable technical conditions for substations to prevent personal electric shock and misoperation. However, how to improve the safety management of the substation and ensure that the substation will not cause accidents due to misoperation is indeed a problem that every substation worker needs to think about seriously. [0003] The main task of substation operation is the operation and maintenance management of power equipment. In the substation operation, one of the major characteristics is that there are many equipments, and the chances of dangerous points or hidden dangers are large and concealed. However, in th...
