The input signal of journey measure and control device, when detecting cabinet door opening without permission, using sound and light signal as output of reporting to the police
Signal；Concentrator station receives remote monitor device output signal by network by stipulations with concentrator station front end processor, is taken by concentrator station
Business device is transmitted in concentrator station monitor workstation, corresponding output sound and light alarm signal in concentrator station monitor workstation.
This utility model can be avoided because opening the security incident that wrong cabinet door occurs, but staff be not turned off cabinet door and from
In the case of opening working site, but can not play alarm function, in cabinet, secondary connection, equipment the most easily aoxidize corrosion of making moist.This
Outward, this electric equipment cabinet door opening-and-closing alarm system needs protocol conversion device could realize signal transmission, and equipment requirements is the most multiple
Miscellaneous, high cost, it is unfavorable for popularizing.
In sum, existing transformer station cabinet door easily passes out of mind closedown, causes the oxidation of secondary connection, equipment to be made moist corrosion,
Require further improvement.
Summary of the invention
The problem closed that easily passes out of mind for existing transformer station cabinet door of the present utility model, it is provided that one can be reported automatically
Digital transformer substation door control system alert, remotely monitoring.
Digital transformer substation cabinet accelerator control system of the present utility model includes limit switch, circuit, communication dress
Putting, control backstage, described limit switch is arranged on circuit and transformer station's cabinet door binding, and cabinet door is opened, and connects report
Alert signal circuit, on the contrary cabinet door is closed and is then disconnected circuit；Described circuit connects optical fiber by cable to be protected
Protection unit, optical fiber protecting equipment connects Field Communicator by optical-fibre channel；Field Communicator divides two bars branch roads defeated
Going out, an on-scene communication branch road directly connects backstage, station by optical-fibre channel, and another telecommunication branch road is led to by optical fiber
Road first connects remote communication devices and connects monitoring backstage again.
Principle of the present utility model is: by equipment such as combination limit switch, communicator, control backstages, it is achieved power transformation
Stand cabinet door long-distance monitoring and alarming function, notify that staff closes transformer station's cabinet door in time, it is to avoid secondary connection, equipment oxygen in cabinet
Change corrosion of making moist.
Between described limit switch and optical fiber protecting equipment, timing module is installed；Mounting terminal row on timing module, end
Son row connected with optical fiber protecting equipment by optical cable；After limit switch Guan Bi, timing module starts timing, if beyond the scheduled time
Then send alarm signal to optical fiber protecting equipment.The Main Function of timing module is normally to open cabinet door to distinguish and forget to close
Closing two kinds of situations of cabinet door, in i.e. surpassing the scheduled time, cabinet door is not closed, then be defaulted as operator and forget to close cabinet door, start and report to the police
Pattern.
Described timing module is also connected the control circuit of audible alarm machine, and after limit switch Guan Bi, timing module starts meter
Time, if beyond the scheduled time, the control circuit of timing module turn on automatically audible alarm machine, audible alarm machine sends sound.Sound
Sound alarming machine can notify that staff at the scene closes cabinet door.
Described timing module is integrated with SR, and SR associates with the control circuit of audible alarm machine, presses multiple
Position button, timing module reclocking, the control circuit of audible alarm machine disconnects.SR can give operator more fully
Transformer station's maintenance time, when preventing operator from safeguarding, system sends the alarm signal of mistake.
This utility model solves the shortcoming and defect of prior art, compared with prior art has a following progress:
1, possess auto-alarm function by this utility model, can effectively remind staff to close cabinet door in time, and then
Avoid device damage.
2, this utility model combined communication device, optical-fibre channel realize telecommunication, can supervise at remote back-office implementing monitoring
Control process is convenient.
3, this utility model uses limit switch and timing module co-controlling alarm signal, both can remind staff and
Time close cabinet door, again can give staff enough open cabinet maintenance time.
