Abstract

The invention provides a detection method of a box-type transformer and the transformer. The detection method comprises the following steps of: ST1, starting a detection program; ST2, judging whetheran oil level state of a transformer chamber meets a preset state or not, if so, performing ST3 detection, and if not, judging that the box-type transformer fails; ST3, detecting environmental parameters of the box-type transformer, and judging whether a triggering condition for starting the fault detection module is met or not; ST4, carrying out detection according to the fault detection module, and judging whether the transformer has a fault or not; and ST5, executing transformer fault protection operation. According to the detection method of the box-type transformer, by setting a multi-level detection program, on one hand, the reliability of operation detection of the box-type transformer is ensured, and secondary damage to normal operation of the transformer due to the fact that a wrong operation instruction is given by misjudgment is avoided; and meanwhile, resource waste caused by continuous operation of a fault detection program is avoided.

Description

technical field

[0001] The invention relates to the technical field of power equipment, in particular to a detection method for a box-type transformer and the transformer. Background technique

[0002] With the increasing scale and complexity of the power grid, the substantial increase in transmission capacity and the increase in voltage levels, the efficiency of power transmission is getting higher and higher, the investment in power grid equipment is getting higher and higher, and the direct and indirect losses caused by sudden failures are also increasing. The bigger it is, how to avoid and reduce losses becomes a very prominent issue. For this reason, the maintenance of power grid equipment has gradually developed from accident maintenance to regular maintenance, and then to condition-based maintenance based on reliability.

[0003] The box transformer is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. According to ...
