Abstract

The invention discloses a capacity-regulating power distribution transformation auxiliary device and a capacity-regulating method. The device comprises a high-voltage side capacity-regulating auxiliary switch arranged on one side of a high-voltage side winding of a distribution transformer and a low-voltage side capacity-regulating auxiliary switch arranged on a low-voltage side winding of the distribution transformer, wherein a plurality of interfaces of the high-voltage side capacity-regulating auxiliary switch are connected with a group of high-voltage side windings; the low-voltage side ofthe distribution transformer comprises a first low-voltage side winding and a second low-voltage side winding connected with the first low-voltage side winding, one end of the first low-voltage sidewinding is further connected with a first switch interface of the low-voltage side capacity-regulating auxiliary switch, and one end of the second low-voltage side winding is further connected with asecond switch interface of the low-voltage side capacity-regulating auxiliary switch. Capacity regulation can be achieved only through one-time operation, arc discharge and other situations caused byinternal operation of the transformer are reduced, meanwhile, loss of the transformer is reduced through capacity regulation, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to an auxiliary device, in particular to an auxiliary device for capacity adjustment, distribution and transformation, and also relates to a capacity adjustment method, which belongs to the technical field of distribution transformer capacity adjustment. Background technique [0002] The distribution transformer is an important equipment in the distribution network system, which completes the final distribution task of power supply. The number of distribution transformers is large and the locations are scattered, and the types of power supply loads are diverse, and there will be loads with large seasonal changes, such as flue-cured tobacco, irrigation, and workshop processing. If the capacity of the configured distribution transformer is fixed, the capacity of the transformer can meet the operating requirements when it is running under light load; when the load increases, the distribution transformer will be overloaded, and the lo...
