Abstract

The invention relates to a switching experiment device for an on-load tap changer. The switching experiment device comprises a power supply, a synchronous driving mechanism, an accompanied on-load tapchanger, an electric reactor and a capacitor, wherein a tested on-load tap changer and the accompanied on-load tap changer are connected with the power supply and are respectively independently connected to one of the electric reactor and the capacitor, and the electric reactor and the capacitor are connected with the power supply; and the synchronous driving mechanism is connected with the accompanied on-load tap changer and the tested on-load tap changer and is used for driving the accompanied on-load tap changer and the tested on-load tap changer to be synchronously switched. According tothe switching experiment device for the on-load tap changer, the switching action of the tested on-load tap changer can be realized under a load condition, the actual operation state is effectively simulated, and the switching experiment equivalence of each performance of the on-load tap changer can be improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment detection, in particular to a switching test device for an on-load tap changer. Background technique [0002] The on-load tap changer is a movable part in the on-load tap changer. Relying on the accurate and timely action of the on-load tap changer, it can not only reduce and avoid large fluctuations in voltage, but also forcefully distribute the load current to ensure the safety of the power system. Reliable operation, increasing the flexibility of power grid dispatching. In order to ensure the safe and reliable operation of the on-load tap changer, it is usually necessary to conduct a switching test on the on-load tap changer. [0003] Due to the complexity of the mechanical mechanism of the on-load tap changer and the variety of mechanical faults, it is very difficult to simulate the common mechanical faults in the actual operating state on a real on-load tap changer. Most of the...
