Detailed Description

In order to provide a convenient temporary fixation, not destroy the wall, and fix effectual transmission line fault detection device scheme, the following description is combined with the description drawings to explain the utility model discloses a preferred embodiment.

Referring to fig. 1 to 5, an embodiment of the present invention provides a power transmission line fault detection apparatus, including: a fixed plate 1, a housing 4 and an operation panel 3; the front surface of the fixed plate 1 is fixedly connected with a machine shell 4, and an operation panel 3 is arranged on the machine shell 4; the four corners of the fixing plate 1 are respectively provided with a mounting hole 8. The bolt is used for permanently fixing the power monitoring instrument. Display lamps 6 are installed on the upper side and the lower side of the machine shell 4, a display screen 2 is installed on one side of the operation panel 3, and a key 5 is installed on the other side of the operation panel. The rear surface of the fixing plate 1 is provided with a mounting groove 9, a horizontal fixing rod 10 is arranged in the mounting groove 9, and two fixing clamps 11 are arranged on the fixing rod 10; the fixing jig 11 includes: a movable clamp plate 111, a fixed clamp plate 112 and a rotating handle 113; one end of the fixed clamp plate 112 is hinged to the fixing rod 10, the position of the hinge point of the fixed clamp plate 112 and the fixing rod 10 is fixed, one end of the movable clamp plate 111 is hinged to the fixing rod 10 and can slide back and forth on the fixing rod 10, and the rotating handle 113 penetrates through the middle parts of the movable clamp plate 111 and the fixed clamp plate 112 and is fixedly connected with the movable clamp plate 111 and in threaded connection with the fixed clamp plate 112.
