- the limit plate is arranged between the first baffle and the second baffle; one end of the locking piece penetrates the first baffle, and the other end is connected with the limit plate to drive the limit
- the plate moves relative to the second baffle to change the gap between it and the second baffle.
- the base is provided with a through hole communicating with the groove, and the through hole is provided with an internal thread;
- the limiting member is a screw rod and is arranged in the through hole on the base.
- the limiting member includes a plurality of support rods, one end of the support rod is hinged with the arrester, and the other end is movably connected with the base.
- the support rods are arranged at equal intervals along the circumferential direction of the arrester.
- the connecting plate is provided with a sliding groove
- the bottom of the base is provided with a sliding block
- the sliding block is located in the sliding groove
- the connecting plate is provided with a weight reduction hole.
- first baffle, the second baffle, and the limiting plate are parallel to each other, and the radial cross-sectional size of the limiting plate is smaller than the radial cross-sectional size of the first baffle and the second baffle.
- the lightning protection device applied to power equipment of the present application has a simple structure, is easy to install, can adjust the orientation of the arrester according to actual needs, and realize the fixed position of the arrester, and is designed to be suitable for various sizes of connectors, so that the application
- the lightning protection device can be installed on the cabinets of various types and sizes of power equipment, which greatly improves the applicability of the lightning protection device.
- Fig. 1 is a schematic structural diagram of a lightning protection device applied to power equipment in Embodiment 1.
- a lightning protection device applied to power equipment including:
- the ball head 2 is connected to the bottom of the arrester 1;
- the base 3 is provided with a groove with a circular cross section
- the limiting member 4 is provided between the ball head 2 and the base 3, and is used to fix the ball head 2 in the groove of the base 3; specifically, on the base 3 A through hole communicating with the groove is provided, and the through hole is provided with an internal thread; the limiting member 4 is a screw rod, and is provided in the through hole on the base 3;
- a connecting piece includes a connecting plate 5, a first baffle 6, a second baffle 7, a limiting plate 8 and a locking piece 9;
- the connecting plate 5 is connected to the base 3;
- the first stop The plate 6 and the second baffle 7 are arranged oppositely, one end of both is connected to the connecting plate 5, and the other end is in a free state;
- the limiting plate 8 is provided on the first baffle 6 and the second baffle 7; one end of the locking member 9 penetrates the first baffle 6, and the other end is connected to the limiting plate 8, which drives the limiting plate 8 to move relative to the second baffle 7, changing The gap between it and the second baffle 7.
- a sliding groove (not shown in the figure) is provided on the connecting plate 5, and a slider (not shown in the figure) is provided on the bottom of the base 3 (Shown), the slider is located in the chute.
