Embodiment Construction

[0040] The present invention will be further described below with the mode of embodiment.

[0041] Such as figure 1 shown. The switch cabinet cable chamber door interlocking device is composed of a front door assembly 100 and a rear door assembly 200, and a state rope 10 and an opening and closing rope 20 are arranged between the front door assembly 100 and the rear door assembly 200; the front door assembly 100 includes a front door frame 110, a front door latch 120, Front door buckle 130, front door button 140, slider latch 150, ground knife slider 160, door latch seat 170, rear door assembly 200 includes rear door frame 210, rear door latch 220, rear door buckle 230, rear door button 240.

[0042] Such as figure 2 As shown, the front door frame 110 and the door latch seat 170 are fixed on the switch cabinet, the front door buckle 130 is fixed on the front door, the front door button 140 protrudes from the front door frame 110 and abuts against the front door buckle 130, ...

Abstract

The invention relates to a switch cabinet cable chamber door interlocking device, which consists of a front door assembly and a rear door assembly, wherein a state rope and an opening and closing rope are arranged between the front door assembly and the rear door assembly, wherein the state rope is connected with a slider latch, a front door press key and a rear door press key, the opening and closing rope is connected with a front door latch and a rear door latch, the front door press key is connected with the slider latch and drives the slider latch to move, the rear door assembly is connected with the slider latch and drives the slider latch to move, the stroke of the front door press key driving the slider latch or the stroke of the rear door press key driving the slider latch is not enough to enable the slider latch to relieve the locking for an earthing knife-switch, and the stroke of the front door press key driving the slider latch and the stroke of the rear door press key driving the slider latch are enough to enable the slider latch to relieve the locking for the earthing knife-switch. According to the technical scheme, opening and closing of interlocking of the front door assembly and the rear door assembly are realized by the opening and closing rope, and interlocking of a front door and a rear door for the slider latch is realized by the state rope, so that the front door assembly and the rear door assembly are connected by a simple and effective method, and the goal of interlocking is achieved.

Description

technical field [0001] The invention relates to an interlock mechanism for a switch cabinet door, in particular to an interlock device for a switch cabinet cable chamber door. Background technique [0002] The medium and low voltage switchgear is equipped with high-voltage and high-voltage power equipment such as circuit breakers and separators. The voltage transmitted by it is measured in kilovolts, and the power transmitted by it is tens of thousands, which shows the huge amount of electric energy it transmits. Therefore, in order to avoid unnecessary consequences and serious losses caused by electric shock injury or accidental power-on when installation, maintenance, maintenance, etc. involve the actual operation that needs to be close to the switchgear, the industry puts forward five prevention requirements for the switchgear. The specific requirements are as follows: [0003] 1. Prevent mis-opening and closing of circuit breakers. [0004] 2. Prevent load opening and...
