Hooking type instrument element mounting plate

Abstract

The invention provides a hooking type instrument element mounting plate. The mounting plate is arranged in an instrument room of a switch cabinet; an upper bent beam is mounted on a top plate of the instrument room; a long square hole for hooking is formed in the front side of the upper bent beam; a lower bent beam is mounted at the lower part of a sealing plate mounted on the rear side of the instrument room; the upper part of the element mounting plate is provided with a folded bent hook; the bent hook is hung on the long square hole in the upper bent beam; and the lower part of the element mounting plate is fastened on the lower bent beam of the instrument room through bolts. The hooking type instrument element mounting plate provided by the invention has the benefits as follows: during element mounting, the mounting plate provided by the invention can be taken down quickly to be separated from a cabinet body, then an element is mounted on the mounting plate, and after mounting is completed, the mounting plate is mounted on the cabinet body; and the structure is simple. Since assembled parts are fewer, the mounting is simpler; in addition, unhooking and hooking are convenient since a hooking manner is adopted. The conventional element mounting plate fixing manner is that the element mounting plate is hung on a side plate on one side, but the hooking type element mounting plate provided by the invention adopts top hooking, so that balance stress and stable fastening are realized.

Description

technical field [0001] The invention relates to the field of electrical switchgear, in particular to a hook-type instrument component mounting plate of an armored metal-enclosed switchgear. Background technique [0002] With the large-scale construction of electrified railways in my country and the continuous deepening of railway system reform, higher requirements are put forward for the safety of traction power supply equipment. Therefore, the demand for high-performance, high-quality, and low-cost integrated equipment on domestic ordinary-speed electrified railways is becoming stronger and stronger. [0003] At present, the installation of the component mounting plate installed in the instrument room of the armored metal closed cabinet is complicated, and it needs to be fixed with four hinge connections and two handle screws, and the force is poor, especially in the case of a large cabinet width. The one-sided column makes the mounting plate sag seriously, which affects t...

[0003] At present, the installation of the component mounting plate installed in the instrument room of the armored metal closed cabinet is complicated, and it needs to be fixed with four hinge connections and two handle screws, and the force is poor, especially in the case of a large cabinet width. The one-sided column makes the mounting plate sag seriously, which affects the performance of electrical components and makes the overall visual sense of the instrument room messy
