Description
Technical field
The present invention relates to electric operation technical field, and in particular to a kind of dress for preventing from being strayed into transformer room in the case of being powered
Put and method.
Background technology
In metallurgical engineering work progress, transformer is frequently accompanied by debugging process as important electric powerplant
The situation of power failure and transmission operation, but transformer room is different from switchgear house, and transformer does not have five anti-devices of power distribution cabinet, constructs
Personnel judge whether transformer runs at the scene, and in addition to contacting the electric personnel of master control room, ear can only be relied on by rule of thumb
Transformer whether there is the sound under running status, once and occur confusing communication or AC fault between field personnel
The problem of when, staff very likely transformer be powered operation in the case of be strayed into transformer room, serious conditions can also be made
Into the generation of personal electric shock casualty accident.
The content of the invention
The purpose of the present invention prevents from being strayed into transformer room in the case of being powered for the defect that prior art is present there is provided one kind
Method.
To achieve the above objectives, the present invention is adopted the technical scheme that：
A kind of device for preventing from being strayed into transformer room in the case of being powered, it is characterised in that including：In transformer body and height
After low voltage side cable installation, the power taking of low-pressure side two-phase is connected to input rectifier out of transformer room, is provided by rectifier
24V DC voltages are to warning lamp and infrared emission alarm, and doorway both sides set infrared emission to alarm respectively in transformer room
The light projector and light-receiving device of device, the light projector and light-receiving device of infrared emission alarm are connected with controller simultaneously, the controller
Inside it is additionally provided with an alarm bell；
The operation once transformer is powered, step down side is powered, then the warning lamp on transformer doorway obtains electroluminescence, table
Show that transformer is in running status, if now still thering is external staff to swarm into transformer room, the red of projector transmitting will be sheltered from
Outside line, light-receiving device can not receive infrared-ray, and the alarm bell set in controller, controller control transformer room is fed back to immediately
Alarm is opened, prompting is strayed into personnel's transformer and is in operation electriferous state, should recess in time.
It is above-mentioned it is a kind of prevent from being powered in the case of be strayed into the device of transformer room, warning lamp is light emitting diode, is set
In the big outer side of door in transformer room, alarm bell is arranged on transformer room's interior wall.
It is above-mentioned it is a kind of prevent from being powered in the case of be strayed into the device of transformer room, system is set among alarm host machine
Put, this main frame can also therefrom draw a signal node and the working condition of infrared emission alarm is reacted directly into master control
Room.Here the not direct control main frame of master control room, simply feeds back to master control room by signal, and master control room is able to know that with the presence or absence of outside
Personnel are strayed into the transformer room of power transmission, convenient that other measures can be taken to prevent the generation of accident, measure bag the very first time
Include and go to observe conditions using before intercommunication contact scene inspection personnel.
It is above-mentioned it is a kind of prevent from being powered in the case of be strayed into the equipment of arrangement and change in the device of transformer room, transformer room
Depressor high-pressure side and high-tension cable all should keep more than 1.5m safe distances.
It is a kind of using prevent be powered in the case of be strayed into transformer room device operating method, it is characterised in that including with
Lower step：
Step 1：In the case where transformer is powered off, device and equipment, ZKS part signals are connect needed for arranging at the scene
Enter among master control chamber system.
Step, 2：Close control button SB1, close transformer room gate.
Step 3：When transformer, which is sent, a little to put into operation, the warning lamp D on transformer room gate is in illuminating state.
Step 4：Under Transformer Operation Status, when someone is strayed into transformer room, alarm host machine ZJ actions, alarm bell JL will be triggered
Send alarm and remind and be strayed into personnel and leave as early as possible.
Step 5：When someone is strayed into transformer room, master control room will receive signal, and contact scene inspection personnel rush for transformation
Device room is observed conditions, and after situation is excluded, ann reset button SB is pressed by patrolman2Alarm can be released and revert to normal shape
State.
Beneficial effect of the present invention include it is following some：1st, this method is made by directly drawing two phase lines from step down side
For power supply, the problem of not only solving installation's power source, and directly can effectively detect whether transformer is in electriferous state,
It other people need not control in addition, use manpower and material resources sparingly, make up and be currently in construction stage transformer indoor transformer and lack five anti-dresses
The problem of putting；2nd, multiple protection measure is this method provide, the transformer room of external staff's mistakenly entering into charged is effectively prevented.This method
First by setting warning lamp on gate on the outside of transformer room, once warning lamp is lit, then it represents that and transformer is in powered
Running status.2nd, infrared emission warning device is set in transformer room doorway both sides, if workmen is ignoring warning lamp
In the case of, transformer room is strayed into, indoor alarm bell alarm will be triggered to be reminded.3rd, a signal node is drawn from alarm host machine
Master control room is connected to, the working condition of infrared emission warning device is fed back to master control room by the signal node, once someone is strayed into change
Staff can notify neighbouring patrolman to rush for transformer room the very first time in depressor room, master control room, go and find out what's going on, resistance
The only generation of accident.3rd, the device employed in this method repeats usability height, is only configured in the construction stage, debugging fortune
It is to be used among recoverable input next item after the completion of row.
