Transformer iron core current data instrument

Abstract

The invention provides a transformer iron core current data instrument. The transformer iron core current data instrument comprises a controller, a 4G module, a warning lamp, a display screen, a current transformer, a solar charging panel, a battery and an alternating current charging module. The transformer iron core current data instrument can regularly collect grounding current data of a transformer iron core, an inspector can directly read the reading in the display screen to obtain the data, and a 4G module of the device can send an alarm short message to a mobile phone of an operator on duty. The charging system is provided with double power supply modes and a battery capable of storing electricity. Measured data are visual and accurate, and the working efficiency can be improved; the alarm function timely eliminates potential safety hazards and ensures safe and stable operation of electric power; flexible power supply can be realized according to different application scenes, and reliable operation of the device system is ensured.

Description

technical field [0001] The invention belongs to the technical field of transformer detection instruments, in particular to a transformer iron core current data instrument. Background technique [0002] The iron core of the substation transformer is normally grounded, and only one point is grounded. If the grounding current is too large, it will cause local overheating of the iron core and damage the insulation. The power transformer is an important electrical equipment in the power system. Once a fault occurs during operation, it will cause serious consequences to the power system. Therefore, inspectors should regularly measure the grounding current of the transformer. [0003] However, the current measurement of the transformer iron core current in the substation still relies on manual work. The operator on duty holds the current clamp meter to measure the calculated value of the transformer iron core flat iron. The grounding down-conductor of the core cannot achieve the f...

Problems solved by technology

[0003] However, the current measurement of the transformer iron core current in the substation still relies on manual work. The operator on duty holds the current clamp meter to measure the calculated value of the transformer iron core flat iron. The grounding down-conductor of the core cannot achieve the functions of real-time measurement data and punctual alarm. It is impossible to know whether the transformer is damaged in time and eliminate potential safety hazards.
