Transformer station storage battery voltage measuring device

The invention relates to a transformer substation storage battery voltage measuring device, which comprises an operation frame and a detector, when the transformer substation storage battery voltage measuring device is used, a rotating handle drives a rotating rod to rotate, two bayonet sockets are driven to be close to or far away from each other at the same time, the distance between the bayonet sockets is made to be the same as the distance between poles, a handheld rod is held tightly to drive a transverse rod to move, and the bayonet sockets are clamped with the poles of the storage battery. The pole is inserted into the cover cylinder, good contact with the pole can be guaranteed under the dual action of the elastic piece and the probe, the measurement result is more accurate, the measurer measures the voltage of the storage battery through the wire under the action of the single-chip microcomputer module, measurement data are displayed on the display screen and automatically stored in the memory card,
