Further describing, when being placed with current monitor in monitoring groove, after described current monitor plug-in mounting enters described monitoring groove, the two fits.
Having the beneficial effect that between monitoring groove and current monitor of this programme leaves no gaps, improve transformer and extraneous insulation effect, reduce the use error of transformer, it is to avoid the impact that impact and the transformer of transformer are caused by external environment to external world.
Further describing, described current monitor includes insulation shell, coil and the ammeter with coils connected in series, when current monitor is placed into monitoring groove, for monitoring the creepage current within transformer.
This programme have the beneficial effect that the coil by current monitor, the creepage current between transformer first and second coil can be monitored in real time, and shown by electric current, creepage current according to current monitor monitoring, judge the quality of insulating materials in transformer, in the service life of estimation transformer, it is judged that transformer is the most qualified, improve the reliability of transformer.
Further describing, the described coil winding inserting end at described current monitor insulation shell and the bottom land near described monitoring groove, described ammeter is arranged on the end face of external end of described insulation shell.
The beneficial effect of this programme, can more be accurately detected the creepage current of transformer, and can be shown by this electric current, and user or quality inspection personnel can be visually observed that the current value of transformer, the accuracy of detection of the current monitor of raising and the detection efficiency of transformer.
Further describing, for the ease of reading the size of current value, described ammeter is digital electronic ammeter.
Further describe, described current monitor is provided with handle.
This programme have the beneficial effect that when transformer is carried out quality testing, handle can be passed through, mount and dismount current monitor quickly and easily, be effectively increased the efficiency of transformer quality inspection.
Further describe, described collar is provided with waterproof apron.
This programme have the beneficial effect that current monitor can be made to be isolated from the outside by collar and waterproof apron comes, can be with water proof and dust proof, it is to avoid the destruction that current monitor is caused by water, dust, extend the service life of current monitor.
Further describing, described insulation shell is epoxide resin material.
