Summarize
STZ and car type automatic device and synchronization instructions, automatic adjustment and automatic frequency offset and instructions
in the integration of instrumentation.
When the generator start-up success, need for parallel operation, can be put into the device.It can identify generator frequency relative to
the size of the power grid
frequency, and generator frequency regulation, when the generator to the grid frequency offset is less than the setting value, the generator
in the power grid voltage phase difference is equal to 0 ° before a moment, a main acousto-optic closing instructions.The device, improves the accuracy of the generator and car operation, reliability, and security, the device adopts
digital control technology, is the most novel design, compact structure, small volume, light weight, technical performance meet the
requirements of CCS specification, is a design, the manufacture, the unit using the ideal choice.Technical performance
1.Device power supply:AC400V or AC100V 50/60Hz
2.Speed control part of the device can work normally when absolute value is less than 3 hz frequency.
3.Speed control of pulse width is 0.1 to 0.5 seconds, adjustable points 0-9 block.0 for test.
4.Frequency offset locking can be within the scope of 0.12 to 0.5 Hz setting.Factory set to 0.3 Hz.
5.Closing order lead time: within 80-400 ms setting.Factory set to 200 ms.
6.Device consumed power:〈5VA
7.The output contact load capacity: AC 380V 3A,DC28V 10A(Resistive load)
8.Environmental conditions: ambient temperature of 0~50°C, relative humidity 95%, with vibration in operation of the ship, oil mist, salt fog.
