Technical Field

[0001] The utility model belongs to the technical field of relay protection, and in particular relates to a wireless remote control device for resetting relay protection. Background Art

[0002] Functional verification of relay protection devices is an important part of the maintenance of secondary devices in substations. During the operation, multiple reset operations are required. If the staff walks to the machine to press the reset button, they need to walk repeatedly, wasting time. The reset button is often wirelessly controlled by a wireless remote control device. The wireless remote control device requires a remote controller, but the current wireless remote control device is prone to accidental touch, causing it to emit an erroneous control signal, resulting in accidental reset of the relay protection, affecting the normal operation of the power system. Utility Model Content

The anti-mistaken touch slide cover 3 and the long-press slide cover 4 can slide along the remote control body 1, and there is a gap between the anti-mistaken touch slide cover 3 and the reset button 2. A top button 11 is arranged on the side of the long-press slide cover 4 close to the reset button 2, and the top button 11 can press the reset button 2 when the long-press slide cover 4 slides to above the reset button 2;

[0025] It should be noted that when the secondary device of the substation is being repaired, the staff needs to walk back and forth to the machine to press the reset button 2. The use of a wireless remote control device can effectively reduce the labor intensity of the staff. The conventional wireless remote control device is triggered when the staff presses it and is closed when it is released. It is also easy to cause accidental touches and affect the normal operation of the power system.
