Background technology
Due in the power lightning protection technology of transformer station secondary system, the failure state of tradition lightning protection device shows or indicating means mostly is the machine or locally displayed, the running status of thunder resisting equipment, life situations, degradation mode all cannot be assessed and early warning, greatly increase accident rate and maintenance difficulties；Due to domestic lightning protection device research and development, produce, test, the technique such as installation is compared external lightning protection device and be there is quality inferior position and technological deficiency, makes lightning protection device become a potential potential faults in transformer station secondary system.
At present after transformer station secondary system power supply TMOV lightning-protection module installation the most no matter, also cannot the duty of early warning TMOV lightning-protection module and protection level, until after lightning protection device damages or causes the system failure, just finding lightning protection device damage.Data cannot be gathered, it is impossible to the determination for the Lightning Strike Risk Evaluation of transformer station and the Lighting protection level of transformer station secondary system equipment provides foundation.Due to without lightning protection device state on_line monitoring function, it is impossible to anticipation accident and assessment lightning protection device duty, it is impossible to ensure the safe operation of equipment.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of transformer station secondary system TMOV lightning protection device mainboard monitor and alarm system, on-line monitoring function is not had with the TMOV lightning-protection module of solution prior art, cannot anticipation accident and assessment lightning protection device duty, it is impossible to ensure the technical problem such as safe operation of equipment.
Technical solution of the present invention:
A kind of transformer station secondary system TMOV lightning protection device mainboard monitor and alarm system, it includes TMOV lightning protection device mainboard, TMOV lightning protection device mainboard is connected with TMOV Condition Monitoring Unit, lightning current monitoring means and temperature monitoring unit wire, TMOV Condition Monitoring Unit, lightning current monitoring means and temperature monitoring unit are connected with micro-control unit wire, and micro-control unit is connected with LCD and buzzer wire.
Micro-control unit is connected with RS485 interface, LED and button wire.
TMOV Condition Monitoring Unit is provided on-off model by an overtemperature protection Thermal Cutoffs, and the Thermal Cutoffs serial or parallel connection of each TMOV lightning-protection module is formed an on-off model dry contact.
The integrating circuit that the current transformer without magnetic core that lightning current monitoring means is made up of polyamide skeleton and enamel wire coil, spacing piezoresistor, rectification, electric capacity, resistance form forms.
Beneficial effects of the present invention:
Feature of the present invention:
The status monitoring signal of TMOV lightning-protection module output and temperature monitoring signal and lightning current signals can be acquired and process by the present invention, and intensity of lightning, thunder and lightning number of times, thunder and lightning time of origin, security protection number of days, TMOV malfunction are recorded, monitored；
Condition Monitoring Unit of the present invention is provided on-off model by an overtemperature protection Thermal Cutoffs; the Thermal Cutoffs serial or parallel connection of each TMOV lightning-protection module is formed an on-off model dry contact; when TMOV major loop Temperature protection disconnects and losing efficacy; this Thermal Cutoffs can synchronize to disconnect and provide alarm signal to be detected break-make by MCU; during disconnection, function links this on-off model of the red sudden strain of a muscle of LED with voice guard, remote signalling relay, ECU, LCD show etc., and protection number of days stops；If change occurs in this switching signal, related circuit and function will change, indicate, and sends fault message by RS-485 interface to backstage；
The integrating circuit that the current transformer without magnetic core that lightning current monitoring means of the present invention is made up of polyamide skeleton and enamel wire coil, spacing piezoresistor, rectification, electric capacity, resistance etc. form is sampled, comprise the circuit such as Anti-surging, rectification, dividing potential drop sampling, electric discharge.The current signal collected by current transformer by the size of current transformer detection thunder and lightning is converted into voltage signal supply ECU to carry out processing and computing, and is shown in exercisable LCD screen.
The present invention has the functions such as real-time monitoring warning, and the TMOV lightning-protection module solving prior art does not has on-line monitoring function, it is impossible to anticipation accident and assessment lightning protection device duty, it is impossible to the technical problems such as the safe operation of guarantee equipment.
