That is, 1. When the mechanism is in the closed state, use the interlock mechanism to lock the door of the ring network cabinet, so that the operator or maintenance personnel cannot open the cabinet; 2. Only in the open state or the ground state, the interlock mechanism will not work will lock the door

Embodiment Construction

[0018] The grounding hard interlock on the load switch mechanism of the medium-voltage AC power distribution ring network cabinet of the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] refer to figure 1 , the present invention provides a grounding hard interlock on the load switch mechanism of the medium-voltage AC power distribution ring network cabinet, including an interlock bracket 1 fixedly arranged on the power distribution ring network cabinet, and the interlock bracket can be set on the power distribution ring network The switch of the cabinet can also be fixed on the door beam. A plurality of door pin sliding sleeves 9 are integrally arranged on the interlocking bracket 1 , and door pins 6 are slidably arranged in the door pin sliding sleeves 9 . The door pin 6 may include a long door pin and a short door pin. The upper part of the door pin 6 is connected with a door pin br...

Abstract

The invention discloses a grounding hard interlocking member on a load switch mechanism of a medium voltage AC power distribution ring network cabinet. The grounding hard interlocking member comprisesan interlocking bracket fixedly arranged on the power distribution ring network cabinet, a plurality of door pins slidingly arranged on the interlocking bracket, a door pin bracket disposed above thedoor pins and fixedly connected with the door pins; a door pin pushing rod driven by a switch main shaft of the power distribution ring network cabinet is arranged above the door pin bracket; and a door lock spring is arranged between the door pin pushing rod and the door pin bracket. The invention is an inserting rod type grounding hard interlocking member, which has stable performance, safety and reliability, simple structure and life testing performance of more than 10,000 times. The grounding hard interlocking member can stably and effectively realize that the door is in a locked state when the switch mechanism is closed, and the door cannot be opened at this time, thereby reducing the life risk of the operator or maintenance personnel during operation or maintenance.

Description

technical field [0001] The invention relates to the field of power distribution ring network cabinets, in particular to a grounding hard interlock on a load switch mechanism of a medium-voltage AC power distribution ring network cabinet. Background technique [0002] Because once the medium and high voltage AC power distribution is misoperated, it will cause life danger to the operators or maintenance personnel, so the load switch mechanism and the ring main unit will be equipped with an interlock mechanism, which locks the cabinet door when the switch is closed, to prevent operators or maintenance personnel from operating. Operation error by maintenance personnel. That is, 1. When the mechanism is in the closed state, use the interlock mechanism to lock the door of the ring network cabinet, so that the operator or maintenance personnel cannot open the cabinet; 2. Only in the open state or the ground state, the interlock mechanism will not work The cabinet door will be lock...
