The high voltage capacitor protects and observes and controls the device function:





The high voltage capacitor protects the protection function of observing and controlling the device
Protect and dispose more than 20 kinds to protect in the storehouse dailily, satisfy users to different electric equipment or protection requirements of the circuit
The protection that users can be according to the needs of actual motion with corresponding apolegamy, really realize for users " Make to measure "
Self-defining to protect function, can realize special protection that does not offer in the storehouse, maximum to satisfied with user's requirement
Combine the programmable function of the ladder-diagram, can realize that protect dynamic current-linited and export reorientation, improve and protect the application flexibility
It is relatively independent to each protect the function, protect definite value, time limit, occlude the condition and very independent setting of current-linited and dispose
Protect realization of function, depend on communication network, meet electric the intersection of system pair and protective card depend on the intersection of and requirement
Can meet users to protective selectivity even more compared with regular electrical relay, promptness, sensibility and authenticity requirement.
Support multiple protecting definite value manually and auto-switch, is suitable for the place where the electric run mode often changes.
And the logging, trouble waveform, the communication network function cooperates closely, it is the electrical relay that protects technical application and reaches a new level
The high voltage capacitor protects and observes and controls the device to protect the protection supported in storehouse
Quick-break protection of the electric current (take the direction to occlude and undervoltage is occluded)
Prescribe a time limit the intersection of electric current and quick-break protection (lead the direction occlude and undervoltage is occluded)
Regular currentlimiting protection (take the direction to occlude and undervoltage is occluded)
Currentlimiting protection (IEC standard is against the characteristic curves of time limit) when instead
After acceleration is protected
The excess load is protected
Current protection of negative sequence
Circuit protection of zero sequence
Single phase earthing is routed (available quintuple harmonics criterion)
Excess voltage protection
Low voltage protection
The pressure loss is protected
Voltage protection of negative sequence
Voltage protection of zero sequence
Overcurrent protection of composite voltage
It has been low for week lightening is protected (take undervoltage to be occluded, slip difference is occluded, the electric current is occluded)
The release of parallel operation of undervoltage is protected (take slip difference to be occluded, the electric current is occluded)
Reclosure (examine pressurelessly, examine in the same term)
Haul oneself willingly into fully
Overheat protective
Reverse power protection
Starting time overlength is protected
Fixed time lag lx overcurrent protection
Against the time limit lx overcurrent protection (IEC standard is against the characteristic curves of time limit)
The non electrical quantity is protected
Self-defining

The high voltage capacitor protects and observes and controls the device to measure the function


The high voltage capacitor protects and observes and controls the applicable scope of device:

? ? The incoming line is protected and observed and controlled
Coil out and protect observing and controlling
The bus section is protected and observed and controlled
Enter the wired and mother to divide into insuring and protecting and observing and controlling by oneself fully
The factory protects and observes and controls with the voltage transformer
The high tension motor is protected and observed and controlled
The high voltage capacitor is protected and observed and controlled
The high-pressure reactor is protected and observed and controlled
Back up protection of the generator and observing and controlling
The intersection of voltage transformer and back up protection and observe and control

The high voltage capacitor protects and observes and controls the device products to sum up:

? ? ? ? The high voltage capacitor protects and observes and controls the integrated trickle of the device to earth and route the function, apply to non-groundedly or is connected the earth electricity by the resistance? ? ? When, adopt fundamental component and power direction of the zero sequence current and voltage of zero sequence as the criterion; Apply it to harmonic component five times and power direction of adopting the zero sequence current and voltage of zero sequence while earthing the electric wire netting by the arc coil as the criterion.
The high voltage capacitor protects and observes and controls the device integrated back up supply to invest the function automatically, adopt the flexible and simple and convenient one distributedly and prepare against and haul oneself willingly into the scheme, haul oneself willingly into and demand to satisfy various, if the incoming line prepares and hauls oneself willingly into (main fact one of two incoming lines one of normal operation fully) Mother divides and prepares against and hauls oneself willingly into (two incoming lines of normal operation are each brought segment generatrix) And multi-channel the incoming line prepares against hauling oneself willingly into fully of special requirement of hauling oneself willingly into etc..
The high voltage capacitor protects and observes and controls the integrated fixed time lag of the device to assist the electric current (Ix) Protect and totally accord with IEC255 canonially and assist the electric current (Ix) against the time limit Protect, so the low tension side zero sequence current protection used for using the voltage transformer in the factory, the unbalance current or neutral point difference stream of the Y-Y connection capacitor is protected.
It totally accords with IEC255 canonial against the current protection of the looks of the time limitly that it is integrated that the high voltage capacitor protected and observed and controlled the device, overheat protective, reverse power protection and starting time overlength is protected, quick-breaking, and the automatic backout function of regular currentlimiting protection that the quick-breaking protection definite value of prescribing a time limit is automatic, suitable for 35KV and following high tension motor protect mainly and stator side of synchro motor mainly protect.
