Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a power transformer maintenance abnormality and defect simulation device. Background Art

[0002] Power transformers are one of the core equipment in the power system. They are mainly used for voltage conversion, that is, to increase or decrease voltage to meet the needs of power transmission and distribution. They are widely used in power stations, substations and user terminals. During long-term operation, power transformers may fail due to various reasons, such as insulation aging, loose joints, internal short circuits, etc. If these problems are not discovered and handled in time, they may cause serious accidents such as power outages, fires and even explosions. Traditional transformer maintenance methods mainly include regular inspections, preventive tests and post-maintenance. However, these methods have the following shortcomings: although periodic inspections can find some obvious problems, it is difficult to find hidden faults in time; the transformer needs to be disconnected from the power grid and a series of electrical tests need to be carried out, which is not only time-consuming and labor-intensive, but also frequently disassembled and assembled, which may cause equipment damage; often, action is taken only after the fault has occurred, at which time it may have caused great economic losses and safety hazards.

[0003] With the development of the power industry and the advancement of technology, traditional maintenance methods alone can no longer meet the requirements of modern power systems. It is particularly important to develop a device that can simulate the operating status of power transformers under different working conditions.

[0004] To this end, the present invention proposes a power transformer maintenance abnormality and defect simulation device to solve the above-mentioned problems. Summary of the invention

[0011] Preferably, an emergency stop button is provided at a corner of one side of the base, and a power interface is provided at the other corner of the base.

[0012] Preferably, a control seat is fixed to the outer end of the defect simulation base, and a plurality of control keys are arranged at the bottom of the control seat.

[0013] Preferably, the defect simulation base is connected to a plurality of the transformer bodies via a wire, and the transformer bodies are arranged in parallel with each other.

[0014] Preferably, a sensor module is provided on the edge of the transformer body, and the sensor module includes a temperature sensor, a voltage sensor and a current sensor.
