Description

Voice alarm device for accidentally opening the door of live cabinet

technical field

The utility model relates to an anti-misoperation device in the electric power industry, in particular to a voice alarm device for preventing misoperation of a charged cabinet door from being opened by mistake on a high-voltage switch cabinet.

Background technique

The high-voltage switch cabinets in the existing power industry are generally installed indoors, especially the primary equipment of 35KV and 10KV systems mostly use indoor high-voltage switch cabinets. During the operation of the switchgear, regular safety inspections are required. However, with the increase of switch cabinets, due to the misoperation of the maintenance personnel in the system, the door of the live equipment cabinet is opened, so that the maintenance personnel touch the live equipment by mistake, causing casualties and accidents to occur from time to time. In order to avoid misoperation and prevent personnel injury accidents caused by equipment misoperation, it is necessary to develop an anti-misoperation alarm device to improve the reliability of power grid operation.

Contents of the invention

The purpose of this utility model is to provide a kind of voice alarm device installed on the high-voltage switchgear with real-time live display and sound and light alarm.

The technical feature of the utility model is: on the basis of considering safety and reliability, it is designed to be a voice alarm device for the false opening of the cabinet door of the charged cabinet, which is composed of a charged display device, an audible and visual alarm, a controller, and a contact switch. It is connected with the induction coil at the input current end and the induction coil at the output current end which are set in the high-voltage switch cabinet; the charged display device and the sound and light alarm are respectively set on the cabinet body of the high-voltage switch cabinet and connected with the controller; the contact switch is set at on the switch cabinet and connected to the controller.

The live display device is a control device for the live display of a high-voltage switch cabinet.

The sound and light alarm is a device that can automatically emit light after a cabinet door is accidentally opened, and at the same time give a voice alarm.

The controller is a control device that has current at the input and output ends of the electrified cabinet, and can automatically emit light and give a voice alarm when the contact switch is opened by mistake.

The contact switch is a multi-contact line control device.

During installation, the controller of the voice alarm device for the false opening of the live cabinet door of the utility model is connected with the input current end induction coil and the output current end induction coil in the high-voltage switch cabinet respectively, and is connected with the charged display device, sound and light through wires. The alarm device and the contact switch are connected. When the switchgear is in the normal working state, the controller is used to control the charging display device to be in the working state, and at the same time, the light is used to indicate the charging; when the switchgear needs to be overhauled, the line must be powered off first before relevant operations can be performed. overhaul. When the high-voltage cabinet is still in the charged state, at this time, the electrical signal generated by the induction coil at the input current end and the induction coil at the output current end of the switch cabinet is input to the controller. At this time, if the door of the high-voltage switch cabinet is opened by mistake, the contact switch will open , under the action of the controller, the sound and light alarm will issue voice prompts and light-emitting alarms; when there is current at the input end of the high-voltage switch cabinet circuit, and there is no current signal at the output end when components fail, if a misoperation occurs to open the switch cabinet, At this time, under the action of the controller, the sound and light alarm is used to prompt that the input end of the circuit is charged, and the output end circuit has no current, so as to achieve the purpose of prompting maintenance personnel. The contact switch is designed as a multi-contact line control device, and its purpose is to prevent the deformation of the switch cabinet door.

The utility model has the advantages that: since the contact switch is designed in the form of multiple contact points, the occurrence of false signals caused when the contact switch breaks down or the cabinet door is deformed is avoided; It can automatically alarm when the door of the high-voltage cabinet is opened by mistake; since the controller is installed and the circuit input and circuit output of the switch cabinet are detected separately, when the input terminal of the switch cabinet is charged and the output terminal is de-energized, the alarm can still be activated. Function; due to reasonable structure, convenient use, safety and reliability, it has great practical and popularization value. the
