Problems solved by technology
In order to prevent misoperation, the staff must protect the electrode of the pressure plate on the live side, but there is no good protection method at present
The commonly used method of winding tape has many disadvantages: dust and oil on the electrodes of the pressing plate make the wrapped tape easy to loosen and slip off, resulting in the loss of protection against electricity; it takes a long time to wind the tape, and it takes about 20 seconds to complete a pressing plate terminal. Low; when the power is restored, it is troublesome to untie the tape, which may cause electric shock accidents for the staff; the on-site operation methods and procedures are relatively random, not standardized and not beautiful; the wrapped tape cannot be reused, which wastes a lot of resources and is not environmentally friendly ;The isolation effect is limited by the performance of the adhesive tape, and the adhesive tape is easily cut through by tools, test leads, and instrument pen tips, and may cause DC grounding or malfunction when accidentally touched

Embodiment Construction
[0025] Embodiments of the present invention are described in detail below:
[0026] Such as Figure 1 to Figure 9 As shown, in the debugging and maintenance work of the relay protection, it is necessary to cut off the power of the preset circuit and disconnect the contact switch of the pressure plate electrode. In order to prevent misoperation, the staff must carry out protective treatment on the pressure plate electrode on the live side. The present invention provides a rubber sleeve 10 for relay protection and automatic pressure plate error prevention, which includes an insulating rubber sleeve 100 with an open end matched with the electrode of the pressure plate, and an insulating cap 200 installed in cooperation with the open end of the rubber sleeve 100. The cap 200 has a The cap extension 220 at the other end inside the sleeve 100 has a permanent magnet installed in the cap extension 220 .
[0027] By fitting the insulating rubber sleeve 100 on the electrode of the pres...

The invention discloses a relay protection and automated pressing plate mistake prevention rubber sleeve, comprising an insulating rubber sleeve which is matched with a pressing plate electrode and is provided with an opening end, and an insulating cap which is matched with the opening end of the rubber sleeve for mounting, wherein the cap is provided with a cap extension part extending to the other end of the interior of the rubber sleeve, and a permanent magnet is arranged in the cap extension part. The relay protection and automated pressing plate mistake prevention rubber sleeve provided by the invention has the advantages that the safety performance of relay protection debugging and maintaining work is improved, the working efficiency is improved, reuse is realized, the performance is reliable, the operation is convenient, and the rubber sleeve is safe, environment-friendly and practical.
Description
technical field [0001] The invention relates to a relay protection device, in particular to a relay protection and automatic pressing plate anti-mistake rubber sleeve. Background technique [0002] In the relay protection debugging and maintenance work of the power substation, it is necessary to cut off the power of the preset circuit and disconnect the contact switch of the pressure plate electrode. In order to prevent misoperation, the staff must protect the electrode of the pressing plate on the live side, but there is no good protection method at present. The commonly used method of winding tape has many disadvantages: dust and oil on the electrodes of the pressing plate make the wrapped tape easy to loosen and slip off, resulting in the loss of protection against electricity; it takes a long time to wind the tape, and it takes about 20 seconds to complete a pressing plate terminal. Low; when the power is restored, it is troublesome to untie the tape, which may cause el...
