[0003] The arc extinguishing grids are independent sheet structures. In order to achieve the arc extinguishing effect of the arc extinguishing grids, in most cases, multiple arc extinguishing grids are installed in parallel. , it is necessary to fix and assemble the arc extinguishing grids one by one, which is time-consuming and laborious, and the efficiency of assembly is also low

Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] see Figure 1-2 As shown, a new type of assembly tool for the arc extinguishing grid includes a body support 1 and an upper hopper 11 fixed on the top of the body support 1 through the installation bracket 14, and the arc extinguishing grid is vertically put into the upper hopper 11 to realize loading. The inner cavity of the body support 1 is surrounded by an arc extinguishing grid installation cavity 101. During the process of assembling the arc extin...

The invention discloses a novel assembling tool for arc chutes. The novel assembling tool comprises a machine body support, an arc chute mounting cavity, an assembling clamp, a clamping electric pushrod, a clamping rod, moving clamp plates, fixed clamp plates, a transposition motor, a station rotating shaft, lifting electric push rods, lifting rods, a limiting push plate, feed hoppers, feeding guide plates, feeding cavities and a mounting support. The novel assembling tool is reasonable in structural design, automatic feed can be achieved through the feed hopper, the arc chutes do not need tobe fixedly mounted one by one, a large quantity of manpower and material resources are saved, and the mounting complex degree of the multiple arc chutes is reduced; and in the assembling process, themultiple arc chutes are clamped in a unified manner, the mounting efficiency of the whole arc chutes is further improved, and one-man operation can be achieved.
Description
technical field [0001] The invention relates to an installation tool for arc extinguishing grids, in particular to a new type assembly tool for arc extinguishing grids, and belongs to the technical field of application of electric safety protection equipment. Background technique [0002] The arc extinguishing grid is one of the basic methods to extinguish the arc. The arc extinguishing grid is generally made of steel sheet. In the AC low-voltage switchgear, when the arc is generated between the contacts, the arc is pulled into the extinguishing arc under the contraction force of the magnetic force line. Arc grid, a long arc is divided into multiple short arcs, when the AC current crosses zero, all the short arcs are extinguished at the same time, due to the near-cathode effect, the initial dielectric strength of 150-250V immediately appears near the cathode of each short arc , as long as the sum of the initial dielectric strengths of all series short arcs is greater than th...
