Abstract
A voice alarm device for preventing mistaken entering into an electric transformer room consists of a travel switch and a voice alarm module, and is mounted inside a box-type substation transformer room, wherein the travel switch is mounted at the top of the inner side of a transformer room door; a 220V power supply is led out of a low-voltage side of the transformer to the travel switch; the travel switch is connected with the voice alarm module; when the transformer room door is in an open state, the travel switch is in a normally-closed state; when the transformer room door is in a closed state, the travel switch is in a normally-open state. The voice alarm device is simple in structure, relatively small in volume and easy to manufacture; the voice alarm device is easy and convenient to mount, the travel switch is mounted only by drilling a small hole in the door, and the voice alarm module is mounted on the wall of the transformer room through screws; the voice alarm device can conveniently play a role of alarming working staff in the daily running and maintaining processes so as to prevent the working staff from entering the electric transformer room to cause personal electric shock casualty accidents.
Description
Technical field
The present invention relates to a kind of voice siren device, specifically a kind of voice siren device that can be applicable to box-type substation transformer room.
Background technology
At present, in overhead transmission line underground retrofit area, switchgear building cannot extending capacity reformation and power supply for construction, temporary electricity place box-type substation more and more general.Box-type substation height room switch cubicle is typically equipped with " five prevent " device, but transformer room lacks " five prevent " device, and space is less.In day-to-day operation tour, maintenance process, after opening chamber door, staff is easy in charged situation, enter transformer room and touches high-low pressure bus by mistake, causes personal electric shock casualty accident.
Summary of the invention
The technical problem to be solved in the present invention is: design a kind of phonetic alarm device, this device is arranged in box-type substation transformer room, in operations staff's day-to-day operation, maintenance process, effectively can prevent from entering transformer room in the charged situation of transformer, personal electric shock casualty accident occurs.
Solving the technical scheme that problem of the present invention takes is: it is made up of a travel switch and a voice alarm module, voice alarm module comprises power module, voice module and loudspeaker, be arranged in box-type substation transformer room, travel switch is arranged on and becomes electric apparatus room door inside top, draw 220 volts of power supplys from step down side and connect travel switch, travel switch connects voice alarm module; Under transformer room door open mode, travel switch is in normally off, and under transformer room's door closure state, travel switch is in normally open.
Good effect of the present invention is: this apparatus structure is simple, and small volume, easily makes; Simple installation, only need make a call to an aperture and install travel switch, be arranged on by voice alarm module screw on transformer room's body of wall on door; It can easily realize in day-to-day operation, maintenance process, and to staff's warning function, can effectively prevent in the charged situation of transformer, operation maintenance personnel enter transformer room, and personal electric shock casualty accident occurs.
Accompanying drawing explanation
Accompanying drawing 1 is schematic diagram of the present invention.
Embodiment
As shown in Figure 1, it is made up of a travel switch 1 and a voice alarm module 2, voice alarm module comprises power module, voice module and loudspeaker, be arranged in box-type substation transformer room, travel switch 1 is arranged on and becomes electric apparatus room door inside top, drawing 220 volts of power supplys from step down side is connected to travel switch 1, and travel switch 1 connects voice alarm module 2; By transformer room door Push And Release, control travel switch 1 change in location.Under transformer room door open mode, travel switch is in normally off, if transformer is charged, voice alarm module 2 forms loop, and loudspeaker can be play as phonetic warnings such as " high-low voltage electrification please note safety " by automatic cycle; If transformer is not charged, voice alarm module 2 non-transformer, does not report to the police; Under transformer room's door closure state, travel switch is in normally open, voice alarm module 2 control loop template, the not sounding of the loudspeaker in voice alarm module 2.
Claims (1)
1. one kind prevents mistakenly entering into charged transformer room phonetic alarm device, it is characterized in that: it is made up of a travel switch and a voice alarm module, voice alarm module comprises power module, voice module and loudspeaker, be arranged in box-type substation transformer room, travel switch is arranged on and becomes electric apparatus room door inside top, draw 220 volts of power supplys from step down side and connect travel switch, travel switch connects voice alarm module; Under transformer room door open mode, travel switch is in normally off, and under transformer room's door closure state, travel switch is in normally open.
