Each parts annexation: current collecting device is connected with CBU-2 expansion interface plate with the CBU-1 master control borad respectively; BUS-4U-37T connects backboard and is connected with the POWER power panel with CBU-2 expansion interface plate with the CBU-1 master control borad respectively; The CBU-1 master control borad is connected with two 100,000,000 fiber optic Ethernets.
Advantage of the present utility model:
1. compact conformation.Although the function of integrated monitoring three-phase data, the phase monitoring device on its physical dimension, size and the market is compared, and is basically identical.
2. realize the monitoring of three-phase synchronism.One table apparatus (master control borad) is finished the collection of three-phase, and the system clock, the data sampling clock that gather the three-phase data are consistent, guarantees the Complete Synchronization of three-phase image data.And sample separately A, B, C three-phase data of three table apparatus on the market can not be accomplished synchronously.
3. automatically record the divide-shut brake coil current information of isolating switch action;
4. clock and timing are carried out clock alignment with GPS, guarantee the accuracy of clock;
5.20KHz sampling rate sampling divide-shut brake coil current information, namely the resolution of 0.05ms catches divide-shut brake coil, energy storage motor current information in the whole course of action of isolating switch, complete documentation action data.
