Description
Technical field
The present invention relates to lightning arrester, particularly to a kind of intelligent lightning protection system being arranged on power circuit, can be real-time
Monitoring surge arrester failure, and auto-alarming.
Background technology
Atmosphere produces negative thundercloud during flowing, along with the accumulation of negative charge in negative thundercloud, its electric field intensity by
Cumulative add, when reaching to a certain degree, i.e. start ladder-type downwards and jump electric discharge, referred to as descending leader electric discharge.When under this
When row guide moves closer to ground object and reaches certain distance, ground object produces point discharge under highfield effect, and
Forming upward leader, and develop towards descending leader direction, both i.e. define lightning channel after joining, and are the formation of thunder therewith
Electricity.It is generally believed that when thunder and lightning descending leader develops downwards from thundercloud, its ladder-type jumps only to be affected by ambient atmosphere,
The target that neither one determines.Only when completing last ladder-type and jumping, it just must select one and be hit object.Cause
This, can install arrester on protected object, makes upward leader and descending leader join, to avoid thunderbolt.
Arrester is exactly the metal object being specifically used to accept thunder and lightning.The metallic rod connecing sudden strain of a muscle is referred to as discharging rod, connects the gold of sudden strain of a muscle
Belong to line and be referred to as lightning conducter, connect the metal tape of sudden strain of a muscle, wire netting is referred to as lighting proof strip, lightning conduction.Discharging rod exceeds protected object, again and greatly
Be joined directly together, when lightning leader close to time, between it and thundercloud, electric field intensity is maximum, thus can be inhaled by the passage of thundercloud discharge
Guide to discharging rod itself, and with grounding device, lightning current is released in the earth safely through downlead, make protected object body
From direct stroke.
Owing to outdoor transmission line of electricity generally sets up in high-altitude, easily become the object that hit of thunder and lightning, thus built on stilts defeated
Generally equipped with overlapping lightning arrester in electric line more.But, after lightning arrester damages, lightning-arrest effect can be lost, as can not be timely
Find the lightning arrester of fault, easily make circuit be struck by lightning, cause large-area power-cuts.
Summary of the invention
For defect of the prior art, the present invention provides the intelligent lightning protection system of a kind of auto-alarming, and monitoring in real time keeps away
The duty of thunder device, when damaging, sends alarm in time, it is to avoid the lightning strike accident that lightning arrester inefficacy causes.
The intelligent lightning protection system of a kind of auto-alarming that the present invention provides, including: it is arranged on keeping away on described power circuit
Thunder device, failure detector, fault message auto-alarming terminal and remote console, described failure detector is used for detecting
The fault message of described lightning arrester, and described fault message is sent to described fault message auto-alarming terminal, described event
Fault message described in barrier information auto-alarming terminal storage, and by described fault message by wireless network be sent to described remotely
Control station, described remote console alerts according to the described fault message received；
Described lightning arrester includes: locating rack and the spark gap being arranged on described locating rack；

Transmitting element, described breakdown judge unit is connected with described ammeter, if current value exceedes setting threshold value, then keeps away described in judgement
Thunder plant failure, and be sent to remotely control by described fault message and fault location information by fault information generation unit
Platform, alerts, and stores described fault message in described fault message memory element simultaneously；
Described remote console receives described fault message and fault location information, alerts.
The intelligent lightning protection system of the auto-alarming that the present invention provides, utilizes current transformer to detect lightning arrester ground path
Current value, judge whether described lightning arrester damages according to size of current, and by fault message auto-alarming terminal by event
Barrier information and fault location information are sent to remote console, carry out fault warning.By native system, it is positioned at remote console
Operator can obtain fault message and abort situation in the very first time, arranges maintainer quickly to keep in repair, it is to avoid due to
The power system that lightning arrester inefficacy causes damages, and causes heavy losses.
Further, described lightning arrester is multiple, and each described lightning arrester is correspondingly arranged on a fault detect dress
Put.
Further, the current value that described breakdown judge unit obtains exceedes current threshold, and persistent period overtime
During threshold value, just judge described lightning arrester fault.
Further, described fault information generation unit is wireless base station apparatus.
Further, described fault message auto-alarming terminal is additionally provided with audible and visual alarm device.
Further, described fault message auto-alarming terminal is additionally provided with positioner.
Further, described fault message auto-alarming terminal includes housing and pcb board, first peace of described pcb board
Equipped with electronic component, second be provided above cooling line, this cooling line connects with cooling gas generating unit, electricity
Movable valve is arranged on described cooling line, and the opening of electrically operated valve is towards described electronic component and makes the cooling air-flow sprayed
Just to electronic component；The opening part of electrically operated valve is additionally provided with the valve plate being perpendicular to cool down air-flow, and valve plate one end is resisted against on spring,
The other end is connected on the opening of electrically operated valve；Described spring housing is located on sliding axle, and sliding axle one end is fixing with valve plate to be connected,

When using gas produced by the cooling gas or cooling gas generating unit introduced from the external world, pass through pipeline
The electronic component 22 importing to heating is other, it is possible to use temperature lower, the most heated by other electronic component 22
These electronic components 22 are cooled down by cooling gas, and cooling effect is more preferable, and rate of cooling faster, is beneficial to realize electricity
The temperature of sub-element 22 maintains in lower level.And, by coil 17 being connected in series to circuit board in order to connect electronics unit
In the circuit of part 22, when electronic component 22 more needs to dispel the heat, and all thermal powers produced by it, derive from electrical power, and
Electrical power is the biggest, and its electric current is the biggest, so coil 17 can produce bigger active force, band moving winding fixing body 21 and valve
The plate 15 right side in figure is moved, to resist elastic force produced by spring 23.When bigger elastic force can be produced, its elastic shape
Becoming the biggest so that the opening of electrically operated valve is the biggest, the flow of the cooling gas that it can pass through is the biggest, and cooling capacity is more
By force.It is achieved thereby that the different cooling effects of the electronic component 22 for different operating temperature, or for same electronic component 22,
Different cooling effects when different temperatures, thus improve cooling gas input device or cooling gas generating unit exists
Import work efficiency during equal number cooling gas, improve cooling capacity.
