The utility model is to realize through following technical scheme:
A kind of transformer gear binary-coded decimal output flash chamber comprises guide rail, is provided with a relay that is used to carry transformer gear binary-coded decimal signal on the guide rail at least, and this relay is by the A tie point and be used to control A tie point coil closed or that break off and form.
Further; Guide rail is provided with and is used for the power module that changing voltage supplies relay coil work use power supply; Article one power supply of this power module output is connected with the relay coil input, and the second power supply of power module output is connected with transformer gear binary-coded decimal output device B tie point.
Further, be provided with one on the guide rail at least and be used for terminal board that electric wire is introduced or drawn.
Further, an end of relay A tie point is connected with terminal board, and the other end is connected with the comprehensive automation device.
Further; The terminal board that above-mentioned guide rail is provided with a relay that is used to carry signal at least and can power supply is introduced or draw; Actual can increase more relay and terminal board as required in the newly-built or transformation process, bigger usage space effectively is provided in transformer station.
The utility model compared with prior art has following advantage:
Because the utility model adopts said structure; Solved transformer gear binary-coded decimal output device B tie point voltage effectively; With the inconsistent problem of comprehensive automation device switching value incoming junction voltage; Thereby make the transformer gear can reach the comprehensive automation device in real time, transfer to master-control room background computer and remote dispatching center by the comprehensive automation device again, realized the remote signalling function.It is simple in structure, and is convenient and practical, is suitable for using in the newly-built or transformation process of transformer station.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
