技术领域technical field

At present, many scientific research institutes have developed a variety of single-phase ground fault line selection devices, fault indication and positioning devices, fault isolation devices and other distribution network line fault diagnosis equipment, and have been widely used in distribution network. However, before these devices leave the factory, how to effectively test the functions and reliability of the devices is a problem faced by the device developers and users. At present, the factory inspection of distribution network line fault diagnosis equipment is usually carried out on small, low-voltage model devices, that is, through the cooperation of small low-voltage transformers, relays and electronic components to simulate the operation of the real distribution network or However, due to the limitation of withstand voltage (<400V) and current capacity (<1A) of the low-voltage simulation device, it is difficult to truly simulate the actual equipment conditions and line operation of the 10kV distribution network (the rated operation of the 10kV distribution network The voltage is 12kV, the current is generally >30A), and it is difficult to realize the effective inspection and testing of the function and reliability of the distribution network line fault diagnosis equipment.
