Description

technical field [0001] The invention relates to the technical field of fault control equipment, in particular to a simulated fault device with temperature control. Background technique [0002] In the actual distribution network, due to the requirement of safe and stable operation, it is generally difficult to conduct fault experiments to study the performance of protection equipment. Building a power supply line of a simulated distribution network for fault simulation experiments is an effective way to conduct distribution network protection research and protection equipment testing. .

[0003] The faults of the distribution network are random and uncontrollable. Therefore, the research on the protection of the distribution network often requires a large number of researches on different types of faults in different locations to better grasp the fault characteristics of the distribution network. Important parameters, the impact of different fault phase angles on electrical equipment is different, but because it is difficult to simulate distribution network faults under different fault phase angles, the existing research on distribution network fault simulation is all in the future Considering the fault phase angle, it leads to some defects in the research of distribution network protection and the test of protection equipment; on the other hand, short circuit, open circuit and ground fault are common faults in distribution network. In the fault simulation experiment The simulation of these faults is essential, and for ground faults, different grounding positions will cause different types of ground faults, among which arc ground faults are more serious faults, the design can integrate multiple faults into one, and according to the needs in the design It is difficult to simulate the corresponding fault devices under a certain fault phase angle
