The invention provides a piece of protection equipment for 6-35kV power grid voltage transformers, comprising voltage transformers. A measurement and control protection device is arranged beside the voltage transformers. Each voltage transformer is internally equipped with a temperature sensor. Current transformers are arranged between the voltage transformers and a power grid bus. High-voltage load switches are arranged between the current transformers and the power grid bus. By adopting the protection equipment for voltage transformers, the real-time working condition of the voltage transformers can be judged comprehensively. By tripping the load switches of the voltage transformers, abnormal bus voltage can be cut off, and damage to the voltage transformers is prevented.
