Description
Technical field
The present invention relates to transformer safeguard procedures, and in particular to distribution transformer protection against electric shock active alarm system.
Background technique
With the managerial promotion of Guo Wang company, power supply company's power grid scale is with fixed assets investment, asset purchase, recombination
Etc. means be rapidly progressed.But part power supply enterprise donor site is located in minority area, and local resident's schooling is universal
The factors such as not high, power grid construction low SI limitation, cause 10kV rural power grids distribution line level of security low, when have personal electric shock
Accident occurs.The distribution transformer in especially some places is console mode mounting means, is particularly easy to generation minor and is strayed into
The event of charging zone occurs.
For site safety, there is an urgent need to it is proposed that the development work of 10kV distribution transformer protection against electric shock active alarm system
Make.10kV distribution transformer protection against electric shock active alarm system energy adaptation to local conditions is adopted for power distribution station charging equipment progress data
Sample judgement is made whether the detection and prompt work of electrification.And mobiles are invaded within the scope of 10 meters of detecting real-time power supply unit
Detection, when discovery has foreign matter to be moved to monitoring region, system can actively issue light prompt.If mobiles do not stop still
Only, then system issues phonic warning prompt.The system is installed on related distribution transformer, can effectively improve rural power grids line powering
Reliability reduces accident rate.
This programme is " actively to utilize existing controller switching equipment, be invested with minimum and realize equipment safety stable operation；Adaptation to local conditions
Associated safety alarming device is selected, prompts electric power netting safe running horizontal comprehensively；The a variety of security alarm devices of flexible utilization, support to match
Electric equipment active safety protection prompt " is general thought, by stages, year is divided to carry out safe distribution of electric power active alarm system Construction, gradually
Promote level of security, the automatization level of power distribution network.
Summary of the invention
The present invention is in order to solve the defects of prior art and insufficient and existing Detection Techniques are mostly infrared acquisition, high temperature

S3, light, sound alarm receive the electric field induction device with door and ultrasonic detector is persistently sent when described
When the high level signal come, described sent from output end immediately with door lasting enable signals to the light alarm module and prolongs
When device, start the light alarm module start flashing alarm；Delayer receive the enabling signal it is for 5 seconds after, by this
Enabling signal is forwarded to sound alarm module, and starting sound alarm module issues the sound alarm of low decibel；If delayer receives
Continue to 10 seconds to the enabling signal, then stop forwarding the enabling signal, and retransmits an electric signal to sound alarm mould
Block, sound alarm module is when receiving the electric signal, starting high-decibel acoustic vocal alarm, if delayer does not receive institute
When stating enabling signal, then stop sending all signals.
Compared with prior art, the present invention having the following advantages and benefits:
1, distribution transformer protection against electric shock active alarm system of the present invention is by obtaining power supply from step down side
Very accurately judge whether equipment is charged；It is filled using the induction that mature microwave Doppler sensor judges as foreign body intrusion
It sets, which is not influenced by factors such as environment temperature, sunshines, can be whether there is motive objects in accurate judgement reconnaissance range
Body, accuracy rate are up to 99%；
2, the low cost of distribution transformer protection against electric shock active alarm system of the present invention is promoted convenient for a wide range of；Due to device
It is traditional material using component, the cost of device can be greatly reduced；Its structure is simple and convenient to operate, flexibly, safely may be used
It leans on.
3, distribution transformer protection against electric shock active alarm system of the present invention is easy for installation, and device only consists of three parts；It is suitble to
Different mounting means can be adapted for double rod frame height, single mast height, base station console mode, floor box etc. since structure is simple
Multiple mounting modes.
