Description
Technical field
The present invention relates to a kind of leak water detdction and positioning systems, more particularly to valve cooling system valve tower internal pipeline leak water detdction
And positioning system.
Background technology
In D.C. high voltage transmission, converter valve is the core equipment of current conversion station, and when normal operation, high current is produced by converter valve
Raw amount of heat, causes the components temperature such as thyristor, reactor to steeply rise, to prevent these components due to temperature is excessively high
Damage, need to configure valve cooling system and be cooled down to change of current valve components.The junction temperature of thyristor can be made to be maintained at by water cooling
Within the scope of safety, thus reliability is enhanced, and improves power delivery capabilities.
Since change of current valve tower generally uses the serial layer distributed structure of assembly type, valve cooling system pipeline complex distribution, pipeline
Model differs and pipe joint is numerous, is susceptible to leakage situation.The leakage of cooling water can bring the safe operation of converter valve
Harm influences the cooling capacity to converter valve, while the water leaked can cause the electric property of lower layer's component to be affected.When
When leakage scenarios occurs in valve cooling system, converter valve normal operation can be influenced, or even burn valve body, jeopardize D.C. high voltage transmission system
System stable operation.Therefore, in high voltage direct current transmission project, it is necessary to carry out online inspection in real time to the valve tower water leakage situation of converter valve
It surveys.
The valve leakage inspector that country's current conversion station generally uses at present is the OSI-301 devices of OSI companies of U.S. production,
The device utilize optical principle, using the fiber laser arrays valve tower bottom inside valve tower whether with the presence of leakage cooling water.Work as valve
There are when ponding, optical fiber blocks tower bottom after being reflected by water, and device is i.e. to DC control and protection system output alarm signal.So
And the equipment failure rate is higher, the more problem of long-term existence device calibration difficulties, false alarm, while can not quick positioning leakage
Point, is not easy to Quick overhaul.
Invention content
In order to solve the problem above-mentioned, a kind of converter valve valve tower leak water detdction of present invention offer and positioning system can be fast
Fast, accurate positioning leakage position, is safeguarded rapidly convenient for maintenance staff.
A kind of leak water detdction and positioning system, if including leak water detdction host, monitoring system, audible-visual annunciator, lead-out wire,
Dry leak water detdction unit, wire jumper, alarm positioning device and splitter；

Each leak water detdction unit includes several leakage inductive lines, wire jumper and clearing end, and several leakage inductive lines pass through jump
Line connects and clearing end terminates.
In order to preferably realize that the present invention, the leak water detdction host are connected by communications protocol and phone, mailbox, mobile phone
It connects, water leakage is converted into alarm signal and sends maintenance staff to, including call voice is reminded, reminding e-mail and short
Letter is reminded.
The leakage inductive line is fixed on by fixing on the pipeline inside converter valve valve tower, when leakage inductive line is examined
It when measuring leakage, transfers signals in alarm positioning device, alarm positioning device starts audible-visual annunciator and sends out alarm, together
When data are uploaded in leak water detdction host, sent out by leak water detdction host.
The principle of the present invention：
Leakage inductive line is made of 4 different types of conducting wires, wherein two are process by conducting polymer, unit
Length resistance value is precisely machined and is definite value, and in No leakage, current value is normal between wherein two conducting wires, when leakage occurs
When, leakage inductive line is compromised object immersion, then is shorted between two conducting polymers, and surveyed current value is made to change,
To send out water leakage alarm.
Position control device carries out the relationship between measuring and calculating resistance and length according to Ohm's law, can be broken down
The position of leakage point, and be intuitively shown in the monitoring system of leak water detdction host, it is quickly found out leak convenient for maintenance staff
It puts and is pocessed.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
