According to the invention, the automatic control and the alarm protection of an electrical circuit can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of electric line equipment, in particular to a long-distance cable carrying electric control lines and electric signal detection. Background technique [0002] The rapid increase in electricity demand has put forward higher standards and requirements for the stable operation of electrical equipment. And as a huge power project at present, once there is a problem with the electrical equipment, the maintenance cost will be relatively high, resulting in direct economic losses. At the same time, the safe operation of production machinery requires complete protection of electrical control circuits in order to eliminate the adverse effects caused by abnormal work or misoperation and avoid accidents. It can be seen that it is very important to ensure the stable operation of electrical equipment. Contents of the invention [0003] In view of the above problems, the present invention provides a long-distance cabl...
