The invention discloses a mutual inductor with a waterproof casing and aims at solving the technical problem that an existing conventional current transformer cannot be applied to a damp or soggy environment and other severe environments for a long period of time due to poor waterproof performance. The specific technical scheme is that the mutual inductor with the waterproof casing comprises a first mutual inductor seat, a second mutual inductor seat, two semi-circular magnet cores wound with enameled coils, two concave sealing boards, two convex sealing boards, two sealing rings and fastening bolts. Two concave sealing boards, two convex sealing boards and two sealing rings form two sealing units. Each sealing unit comprises a concave sealing board, a convex sealing board and a sealing ring. The first mutual inductor seat and the second mutual inductor seat are identical in structure, of symmetrical structures and provided with magnet core installing grooves. The end face of the first mutual inductor seat is symmetrically provided with two sealing board installing grooves.
Description
technical field [0001] The invention relates to a transformer structure for detecting state parameters of a high-voltage cable, in particular to a transformer with a waterproof shell for detecting current for a high-voltage cable. Background technique [0002] With the rapid development of large and medium-sized cities in my country and the requirements of urban planning, the scale of power transmission and transformation networks in power systems is also increasing, especially the high-voltage transmission and transformation networks of 110kV and above. High-voltage cables have been widely used in high-voltage power transmission and transformation networks due to their advantages such as less land occupation, convenient laying, personal safety guarantee, high power supply reliability, and less maintenance workload. Most of this type of high-voltage cables are installed by direct burial, tunnel or bridge. The traditional manual inspection and maintenance method is time-consu...
