Embodiment
[0050] The embodiment of the present application discloses an auxiliary protection device for a busbar of a power distribution cabinet. refer to figure 1 , including box 1, box 1 is composed of transformer cabinet 2 and multiple cabinets, the cabinet includes incoming line cabinet 3, capacitor cabinet 4 and outgoing line cabinet 5, transformer cabinet 2 is used to connect the high-voltage bus, and the high-voltage bus passes through After the step-down device in the transformer cabinet 2 is depressurized, the high voltage becomes a low voltage. Then the low voltage passes through the conversion of the incoming line cabinet 3, the capacitor cabinet 4, and the outgoing line cabinet 5 to deliver the voltage. Therefore, what the incoming line cabinet 3 , the capacitor cabinet 4 , and the outgoing line cabinet 5 are connected to is the voltage after the transformer cabinet 2 has stepped down. The transformer cabinet 2 is provided with a main line inlet 6 for the high-voltage busb...

The transformer cabinet is provided with a general inlet for the busbar to pass through, and the cabinet is provided with a wire inlet hole connected to the wire cabinet; The box body is also provided with a detection device and a heat dissipation device, and the detection device includes a data processing module, a detection module, a display module and an alarm module; the application has the technical effect of quickly realizing the protection function for the high-voltage bus.
Description
technical field [0001] The present application relates to the technical field of power system busbar protection, in particular to an auxiliary busbar protection device for a power distribution cabinet. Background technique [0002] The main function of the substation power distribution cabinet is to open and close, control and protect the electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The incoming terminal of the cabinet. [0003] In recent years, with the continuous acceleration of power grid construction, the number of new substations is increasing year by year, and the number of various types of busbars is also increasing. Therefore, the pressure on the maintenance of busbars in substation distribution cabinets is also increasing year by year. As the main current channel of the substation, the busbar's operation status will have an important impact on the safe and stable operation of the p...
