Description

Technical Field

[0001] The utility model belongs to the technical field of safety warning signs, in particular to a safety warning sign for a protection screen of a transformer substation protection device used in an electric power system. Background Art

[0002] The protection screen of the substation protection device is an important device used to monitor, operate and control the substation protection device. It is a very important part of the substation protection system and can effectively ensure the safe operation of the substation and the integrity of the equipment.

[0003] According to the "Electric Power System Safety Operation Regulations", when relevant maintenance work is carried out on the secondary circuit, the maintenance equipment and operating equipment should be distinguished by obvious signs on the protection screen of the substation protection device.

[0004] At present, the method used to distinguish and warn maintenance equipment and operating equipment is to stick a warning sign with glue in front of the protective screen of the protective device, or to use tape to fix a red banner with warning words on the front end of the protective screen of the protective device. Firstly, this method will cause pollution to the protective screen of the protective device, and the residual adhesion is difficult to remove. Secondly, it is difficult to clean the warning sign after it is contaminated, so that the warning sign cannot be used again, which in turn causes a waste of cost. Utility Model Content

[0029] The front end of the main plate 101 and the front end of the auxiliary plate 102 are both made of stainless steel.

[0030] As can be seen from the above, by setting the safety warning words 105 of the protection screen of the substation protection device on the main plate 101 and the auxiliary plate 102, when in use, according to the state of the substation protection device, the corresponding safety warning words 105 are selected, the main plate 101 and the auxiliary plate 102 are unfolded, and fixed by the installation mechanism 200, and the warning line 104 is painted with a striking color such as red, which can attract the attention of the crowd and further improve the safety warning effect.

[0031] After use, the main plate 101 and the auxiliary plate 102 are folded by the hinge 103, so as to reduce the volume of the safety warning sign for easy storage. The main plate 101 and the auxiliary plate 102 are made of stainless steel, so that the safety warning sign is waterproof, not easy to damage, easy to clean, reusable and has a long service life.

[0032] Embodiment 2: This is the second embodiment of the utility model, including a mounting mechanism 200 , which includes a substation protection screen 201 . A limiting component is provided at the front end of the substation protection screen 201 , and the limiting component is used to limit the position of the main plate 101 and the auxiliary plate 102 .

[0033] The limiting assembly includes two limiting grooves 202 relatively fixedly installed at the front end of the substation protection screen 201. Two bottom grooves 203 are relatively fixedly installed at the front end of the substation protection screen 201. The limiting grooves 202 are located above the bottom grooves 203. Bottom plates 204 are fixedly installed at the lower ends of the two bottom grooves 203. Snap-in plates 205 are slidably inserted inside the two limiting grooves 202. The two snap-in plates 205 are movably connected to the two bottom grooves 203 respectively. The lower ends of the two snap-in plates 205 are respectively in contact with the upper ends of the two bottom plates 204. Connecting plates 206 are fixedly installed at the front ends of the two snap-in plates 205, and the connecting plate 206 arranged on the left side of the substation protection screen 201 is fixedly connected to one side of the main plate 101.

[0034] The limiting assembly also includes a plurality of guide grooves 207 fixedly installed inside the auxiliary plate 102, and L-shaped connecting plates 208 are slidably installed inside the plurality of guide grooves 207, and the front ends of the plurality of L-shaped connecting plates 208 are fixedly connected to the connecting plate 206 arranged on the right side of the substation protection screen 201.

[0035] A limiting plate 209 is fixedly installed at the front end of each of the guide grooves 207 , and the limiting plate 209 limits the position of the vertical plate of the L-shaped connecting plate 208 .

[0036] As can be seen from the above, by welding the limit groove 202 and the bottom groove 203 at the door frame of the substation protection screen 201, when the substation protection screen 201 is needed to warn, by unfolding the main plate 101 and the auxiliary plate 102, the clamping plates 205 set on both sides of the main plate 101 and the auxiliary plate 102 are respectively inserted from the upper ends of the two limit grooves 202 into the bottom groove 203, and the bottom plate 204 further restricts the clamping plates 205, so that the two clamping plates 205 are clamped and fixed, that is, the main plate 101 and the auxiliary plate 102 are installed at the front end of the substation protection screen 201 to play a safety role. The function of warning is that when the warning is not needed, the main plate 101 and the auxiliary plate 102 are pulled upwards, and the snap-in plate 205 is pulled out of the limit groove 202 and the bottom groove 203 to disassemble the main plate 101 and the auxiliary plate 102, thereby making the installation and disassembly of the safety warning sign convenient and quick. Secondly, there is no need to install the warning sign by gluing, thereby avoiding sticky substances remaining on the substation protection screen 201 and being difficult to remove, causing the substation protection screen 201 to be contaminated. Finally, it can avoid the situation where the safety warning sign is very easy to fall off and fails to serve as a warning.

[0037] By pulling the clip plate 205 on one side of the auxiliary plate 102 to the side, the L-shaped connecting plate 208 slides inside the guide groove 207 and is gradually pulled out, so that the distance between the clip plate 205 and the auxiliary plate 102 can be adjusted, and then the distance between the two clip plates 205 can be adjusted to adapt to the installation of safety warning signs on substation protection screens 201 of different widths, thereby improving the practicality of the safety warning signs.
