signal transformer

Measuring point line extended through the train transformer box under the train connected to the test system, not only the interference signal will introduce into the test system, lower signal-to-noise ratio, and in seriously condition the interference signal will be effective signal.

车下测量点的线路经由列车变电箱延长至车厢内测试系统，不仅会将干扰信号引入测试系统，降低信号的信噪比，严重时干扰信号会将有效信号淹没。

The utility model relates to a railway signal device, in particular a railway signal transformer box, including a box body, a box cover, a lock and an ear handle.

本实用新型涉及铁路信号设施，尤其是一种铁路信号变压器箱。
