Relay protection secondary operation isolation device

Abstract

The invention relates to a relay protection secondary operation isolation device. At present, in order to prevent a worker from mistakenly contacting and mistakenly touching the wiring terminal of anoperation terminal strip and mistakenly touching and mistakenly operating the operation terminal in operating, the operating terminals and devices in the working protection screen cabinet strip need to be obviously isolated, striking warning signs need to be arranged, and operation safety is guaranteed. The relay protection secondary operation isolation device comprises a stretchable red warning strip cloth (1) and a cylindrical warning strip cloth storage box (2). The stretchable red warning strip cloth is connected with the cylindrical warning strip cloth storage box, the cylindrical warningstrip cloth storage box is made of PVC materials, the reel spring is fixed in the cylindrical warning strip cloth storage box, free stretching and retracting of the warning strip cloth are guaranteedthrough the reel spring, and white characters of operation equipment are printed on the stretchable red warning strip cloth. The relay protection secondary operation isolation device is applied to the relay protection device.

Description

Technical field: [0001] The invention relates to a secondary operation isolating device for relay protection. Background technique: [0002] At present, when working in the substation protection device screen cabinet, in order to prevent the staff from accidentally touching and accidentally touching the terminals of the running terminal block, as well as the protection device running by mistake, it is necessary to connect the terminals running in the working protection screen cabinet and The device is clearly isolated, and eye-catching warning signs are set up to ensure safe operation. However, at present, the isolation warning devices used by operation and maintenance personnel are various in style and inconsistent in size, which do not correspond to the actual specifications of the on-site equipment. The arrangement of safety measures for the operation and maintenance personnel will bring great inconvenience to the on-site construction work of the staff, and often hinder t...

Problems solved by technology

However, at present, the isolation warning devices used by operation and maintenance personnel are various in style and inconsistent in size, which do not correspond to the actual specifications of the on-site equipment. The arrangement of safety measures for the operation and maintenance personnel will bring great inconvenience to the on-site construction work of the staff, and often hinder the work. The personnel work normally, and even for the convenience of work, the staff removes the safety measures at will, which brings great safety hazards and operation risks to the work.
