[0023] like Figure 1-2 It is a structural schematic diagram of a reactive power automatic compensation controller of a preferred embodiment of the utility model. In this embodiment, a reactive power automatic compensation controller includes a base 1 and an upper cover 11. A connecting seat 2 is fixedly connected to both sides of the rear end face of the base 1, and a first fixed seat 3 is fixedly connected to both sides of the front end face of the base 1. At the same time, a rotating seat 4 is fixedly connected to the rear end face of the upper cover 11 at a relative position to the connecting seat 2, and a second fixed seat 5 is fixedly connected to the front end face of the upper cover 11 at a relative position to the first fixed seat 3. The rotating seat 4 is rotatably connected to the connecting seat 2, so that the upper cover 11 can be flipped on the base 1, and the first fixed seat 3 and the second fixed seat 5 are locked with each other through a locking device 8. Combined with the above-mentioned structural design, the problems raised in the background technology are effectively solved.
