Embodiment Construction
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] Such as figure 1 As shown, the power control cabinet of the present invention includes a cabinet body 1, a working room, and an installation hole, and a hanging point is arranged on the top plate of the cabinet body 1. The point is a suspender 2 welded with the cabinet body 1 or connected with a plurality of screws, and a suspension hole 3 is arranged on the suspender 2 . Since the suspender 2 is welded to the top plate, or multiple screws are used to connect it to the top plate, the hoisting stress points increase. Since the weight of the power control cabinet is constant, the suspender 2 is more stressed than one of the lifting points. The point is firm and durable, and it is not easy to deform when hoisting.
[0014] The suspender 2 of the power control cabinet of the present invention can be made of some metal materials with strong mechanical str...

The invention discloses an electric control cabinet which comprises a cabinet body, a working chamber and a mounting hole. A suspension point is arranged on a top plate at the upper part of the cabinet body; the suspension point arranged on the top plate at the upper part of the cabinet body adopts a suspension rod which is welded with the cabinet body or connected with the cabinet body through a plurality of screws; and lifting holes are arranged on the suspension rod. Two lifting holes can be arranged in the suspension rod. The suspension rod is made of angle iron. The electric control cabinet adopting the structure has the advantages that as the suspension rod is welded with the top plate or connected with the top plate through the screws, the quantity of the hoisting stress points is increased, compared with a common electric control cabinet with one stress point, the electric control cabinet is firm and durable, the suspension rod is not easy to fall off during hoisting and not easy to become deformed when a heavy electric control cabinet is hoisted, the installation and the maintenance are convenient, the safety of operating personnel and a console cabinet can be ensured, and the occurrence probability of safety violations is reduced. Two lifting holes are arranged on the suspension rod, which are beneficial to the stability of the electric control cabinet during hoisting, stable hoisting can be performed, and large swinging cannot occur.
Description
technical field [0001] The invention relates to a power control cabinet, in particular to a power control cabinet with firm hanging points, and belongs to the technical field of power control cabinets. Background technique [0002] Power control cabinets are widely used in power systems, and there are certain requirements for their safety and other specifications, such as IEC60439-1 (low-voltage switchgear and control equipment), GB7251 (low-voltage switchgear) and ZBK36001 (low-voltage withdrawable Switchgear) have made normative requirements for it. At present, for the control cabinets widely used in the market, for the convenience of transportation and installation, suspension rings are mostly installed on the upper part of the control cabinets. The lifting ring is installed on the top plate of the control cabinet body by screws or spot welding. Due to the weight of the power control cabinet and the weight of the internal components, the lifting ring is easy to fall off ...
