Putian Electric Industry Bureau, Fujian Electric Power Co., Ltd., Putian 351100, Fujian, China Abstract：The inductive live show interlock device now widely used in the domestic markets has no automatic intelligent control function of the reference threshold, and it needs service men to go to the scene to uncover and readjust the reference threshold, which wastes great amount of manpower and material resources. In view of this problem, this paper developed an intelligent inductive HV interlock device with live show, which could simply and conveniently use the remote control to switch the inductive value to the reference value without the trouble of uncovering the equipment. Another more prominent characteristic of this equipment is its ability to intelligently adjust the reference value, which can automatically output an adjusted reference threshold value by detecting the inductive value. It was proved in practical uses that this equipment could be applied to the electrical equipment of the transformer substitution，and its operation would be convenient and easy.
