Description

Technical Field

[0001] The invention relates to the technical field of transformer substations, in particular to an anti-foaming cabinet type transformer substation with an automatic protection function. Background Art

[0002] The power industry is a pillar industry related to the national economy and people's livelihood. Substations are the most critical link in the power system. Ensuring the safety of substation auxiliary equipment and environment is one of the key points of power operation. In order to transmit the electricity generated by the power plant to a distant place, the voltage must be increased and converted into high voltage electricity. When it reaches the user, the voltage must be reduced as needed. This work of raising and lowering voltage is completed by substations. The main equipment of substations is switches and transformers.

[0003] Cabinet substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device, which are prefabricated indoor and outdoor compact distribution equipment arranged in one according to a certain wiring scheme, that is, the functions of transformer step-down and low-voltage distribution are organically combined.

[0004] When the cabinet-type substation is in use, heat dissipation holes are generally opened on the surface of the cabinet shell for the heat dissipation effect of the cabinet-type substation. In emergency situations such as heavy rain or water accumulation, external water enters the cabinet through the heat dissipation holes, and water accumulates in the inner cavity of the cabinet-type substation. When there is too much water accumulation, the cabinet-type substation is soaked, which affects the normal use of the cabinet-type substation after the cabinet-type substation is restored. At present, some cabinet-type substations do not have drainage devices inside, or the drainage devices are connected to the outside world and have a certain moisture return phenomenon, which also affects the normal use of the cabinet-type substation.

Since the substation body 6 is bolted to the surface of the lifting plate 94, the substation body 6 can be moved upward.

[0049] It is worth noting that since a plurality of threaded rods 93 and threaded sleeves 92 work together to raise the lifting plate 94, the thread directions and specifications of the threaded rods 93 on both sides should meet the working requirements.

[0050] Support seats 14 are rotatably provided on both sides of the surface of the first transmission rod 91, and the other end of the support seat 14 is fixed to the inner cavity of the cabinet shell 1.

In this embodiment, through the arrangement of the belt body 111, the driving pulley 112, the driven pulley 113, the second transmission rod 114 and the third transmission rod 115, when the threaded sleeve 92 rotates, the driving pulley 112 fixed on the surface of the threaded sleeve 92 can drive the driven pulley 113 and the second transmission rod 114 to rotate through the belt body 111, and then under the action of the bevel teeth on the other side of the second transmission rod 114, the third transmission rod 115 rotates.

[0053] The moisture-proof mechanism 12 includes a cam 121 fixed to the surface of the third transmission rod 115, and a plug plate 122 is slidably fitted on the surface of the cam 121. Telescopic rods 123 are arranged on both sides of the surface of the plug plate 122. The other end of the telescopic rod 123 is fixed to the surface of the placement plate 102. A spring 124 is sleeved on the surface of the telescopic rod 123. One end of the spring 124 is fixed to the surface of the placement plate 102, and the other end of the spring 124 is fixed to the surface of the placement plate 102. The surface of the spring 124 is fixed to the surface of the placement plate 102. In this embodiment, through the arrangement of the cam 121, the plug plate 122, the telescopic rod 123 and the spring 124, when the third transmission rod 115 rotates, the cam 121 fixed on the surface of the third transmission rod 115 can rotate. Under the action of the shape of the cam 121, the plug plate 122 can be squeezed and moved downward, and the plug plate 122 can be fitted to the part where water flows in the water trough 101. Under the action of the telescopic rod 123 and the spring 124, the plug plate 122 moves toward the placement plate 102.

[0054] The waterproof mechanism 13 includes connecting rods 131 fixed on both sides of the surface of the plug plate 122, and the surface of the connecting rods 131 is fixed with blocking plates 132, which slide in the grooves on the surface of the cabinet shell 1. In this embodiment, through the arrangement of the connecting rods 131 and the blocking plates 132, when the plug plate 122 moves upward, the blocking plates 132 are lifted up under the action of the connecting rods 131.

[0055] The blocking plate 132 slides on the surface of the cabinet door 5, and the material of the blocking plate 132 is rubber. In this embodiment, through this arrangement, under the action of the blocking plate 132, the splicing parts of the cabinet doors 5 on both sides can be sealed, thereby improving the waterproof effect of the cabinet doors 5 on both sides.

[0056] Working principle: When in use, under the action of the control unit shell 2 and the solar panel 3, energy is stored for emergencies after power failure of the substation body 6. In daily work, under the action of the heat exchange fan 15, the air in the inner cavity of the cabinet shell 1 can be discharged to the outside through the exhaust hole 16 to achieve the purpose of moisture-proof.

[0057] When heavy rain or water accumulation occurs, if the substation body 6 stops working, the motor 71 can be operated under the action of the control module inside the control unit shell 2, and then the rotating rod 72 and the winding drum 73 are rotated under the action of the motor 71. When the winding drum 73 rotates, the connecting block 75 can drive the sealing plate 85 to move under the action of the connecting line 74 and the fixed pulley 76, and then with the assistance of the track bar 81, the ball 82, the driving shaft 83 and the rotating block 84, several sealing plates 85 are tightly fitted to the inner cavity of the cabinet shell 1, so as to achieve the purpose of blocking the exhaust hole 16 and prevent heavy rain or water accumulation from entering the inner cavity of the cabinet shell 1. After the waterproof work is completed, the sealing mechanism 8 is reset under the action of the motor 71, so that the exhaust hole 16 can work normally.

[0058] When the motor 71 drives the sealing mechanism 8 to work, the first transmission rod 91 can also start working under the action of the rotating rod 72. Under the action of the first transmission rod 91, the threaded sleeve 92 and the threaded rod 93, the lifting plate 94 drives the substation body 6 to be lifted, so that the height of the substation body 6 changes, reducing the possibility of the substation body 6 contacting the water on the lower side. After the waterproofing work is completed, under the action of the motor 71, the lifting mechanism 9 is reset, and then the height of the substation body 6 is lowered, so as to facilitate the maintenance of the substation body 6 or lower the center of gravity of the substation body 6.

[0059] When water enters the cabinet shell 1 and the lifting mechanism 9 is working, the cam 121 rotates under the action of the belt body 111, the active pulley 112, the driven pulley 113 and the second transmission rod 114, and then the plug plate 122 is moved away from the water outlet of the water trough 101 under the action of the telescopic rod 123 and the spring 124, so that the water flow can enter the water trough 101 under the leakage setting of the placement plate 102 and the lifting plate 94, and the water is discharged to the outside under the action of the drain pipe 103. After the waterproof work is completed, under the action of the motor 71, the moisture-proof mechanism 12 is reset, thereby blocking the water trough 101 to prevent external water vapor from returning to the cabinet shell 1 through the drain pipe 103.

[0060] When the cam 121 drives the plug plate 122 to move upward, the connecting rod 131 fixed on the surface of the plug plate 122 can drive the plug plate 132 to rise, and one side of the plug plate 132 slides against the surface of the cabinet door 5, thereby improving the waterproof effect of the cabinet door 5.
