Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-4, the utility model provides a technical solution: the utility model provides a safety guard for power transformer terminal, includes the ware body 1, and square groove 11 has been seted up to ware body 1 up the up end, is provided with the terminal in the ware body 1, stretch into and swing joint has safety guard 12 on the square groove 11, be provided with safety mechanism 2 between safety guard 12 and the ware body 1, terminal and 2 electric connection of safety mechanism.
When the safety cover 12 is completely buckled, the first conducting strip 24 and the second conducting strip 25 at the bottom of the Z-shaped block 22 are contacted, so that the conducting wires 26 on the first conducting strip 24 and the second conducting strip 25 are communicated, so that the power line connected with the conducting wires 26 can normally supply power to the power transformer, when the safety cover 12 is not completely buckled, the first conducting strip 24 on the Z-shaped block 22 is not contacted with the second conducting strip 25 due to the elasticity of the supporting spring 23, so that the power transformer is difficult to normally work, namely, the power transformer can normally work only when the safety cover 12 is completely buckled, so that whether the safety cover 12 is well installed or not can be checked according to the method, and the safety is higher.
The Z-shaped block 22 is fixedly connected with an elastic telescopic pad 3.
The bottom of the safety cover 12 is fixedly provided with a notch corresponding to the safety mechanism 2.
The square groove 11 is adjacently provided with a heat insulation cavity 41, the heat insulation cavity 41 is arranged in the device body 1, the heat insulation cavity 41 is connected with an insulation block 4 in a penetrating and sliding manner, a strong spring 42 is fixedly connected to the insulation block 4, a hot fuse 43 is fixedly connected to one side of the insulation block 4, the hot fuse 43 penetrates and extends out of the heat insulation cavity 41 in a sliding manner, and one end of the hot fuse 43 penetrating and extending out of the heat insulation cavity 41 is fixedly connected to the inner wall of the device body 1.
The during operation, when the inside short circuit of power transformer, the power transformer short circuit produces a large amount of heats, thereby fusing hot melt 43, thereby insulating block 4 removes left and separates first conducting strip 24 and second conducting strip 25 under strong spring 42's effect owing to lose the spacing of hot melt 43, thereby cut off the power supply to this power transformer, prevent that short circuit harm from further expanding, thereby the design of elastic expansion pad 3 makes insulating block 4 can be easier when removing left squeeze Z word piece 22 and first conducting strip 24 rebound and second conducting strip 25 separation on it.
Annular 52 has been seted up in the safety guard 12, a plurality of groups of fixedly connected with water ring 5 that stop in the annular 52, run through in the annular 52 and stretch out and a plurality of groups of water swelling seal ring 51 of fixedly connected with, and a plurality of groups two liang of crisscrossings of water ring 5 and a plurality of groups of water swelling seal ring 51 are the labyrinth design.
During operation, when power transformer intake, water at first gets into in the annular 52, thereby water can stop more time owing to meet water inflation seal ring 51 and the labyrinth design between the water ring 5 of stopping water, makes meet water inflation seal ring 51 fully expand when in the annular 52 to plug the clearance between safety cover 12 and the square groove 11 and seal it, prevent that rivers from going into to make its inside short circuit in the power transformer.
The working principle is as follows: the safety cover 12 is inserted into the square groove 11 where the body 1 is located, when the safety cover 12 moves downwards, the Z-shaped block 22 at the bottom of the square groove 11 is pressed and driven to move downwards, when the safety cover 12 is completely buckled, the first conducting strip 24 and the second conducting strip 25 at the bottom of the Z-shaped block 22 are contacted, so that the conducting wires 26 on the first conducting strip 24 and the second conducting strip 25 are communicated, so that a power line connected with the conducting wires 26 can normally supply power to the power transformer, when the safety cover 12 is not completely buckled, the first conducting strip 24 on the Z-shaped block 22 is not contacted with the second conducting strip 25 due to the elasticity of the supporting spring 23, so that the power transformer is difficult to normally work, namely, the power transformer can normally work only when the safety cover 12 is completely buckled, and whether the safety cover 12 is well installed or not can be checked according to the method, and the safety is higher;
when water enters the power transformer, water firstly enters the annular groove 52, and the water can stay for more time due to the labyrinth design between the water swelling water stop ring 51 and the water insulation ring 5 when passing through the annular groove 52, so that the water swelling water stop ring 51 is fully swelled, a gap between the safety cover 12 and the square groove 11 is plugged, and the water is sealed, so that the water is prevented from flowing into the power transformer to cause the internal short circuit of the power transformer;
when the inside short circuit of power transformer, power transformer short circuit produces a large amount of heats, thereby fusing hot melt silk 43, insulating block 4 is thereby because the spacing of losing hot melt silk 43 removes left under strong spring 42's effect and separates first conducting strip 24 and second conducting strip 25, thereby carry out the outage to this power transformer, prevent that the short circuit harm from further expanding, thereby the design of flexible pad 3 makes insulating block 4 can be more easy when removing left squeeze move Z word piece 22 and first conducting strip 24 rebound and second conducting strip 25 separation on it.
