Description

Technical Field

[0001] The utility model relates to the field of dry-type transformer electric boxes, in particular to a boom-type dry-type transformer electric box suitable for basements. Background Art

[0002] The cooling methods of dry-type transformers are divided into natural air cooling (AN) and forced air cooling (AF). In natural air cooling, under normal use conditions, the transformer can operate continuously at rated capacity for a long time. In forced air cooling, under normal use conditions, the transformer output capacity can be increased by 50%, which is suitable for intermittent overload operation or emergency overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be in long-term continuous overload operation.

[0003] Dry-type transformers are widely used. Dry-type transformers in underground substations or basements often have problems with poor ventilation and high humidity. When a boom-type installation method is adopted, the contact between the electric box and the ground can be reduced, and the impact of ground moisture on the electric box can be further reduced. However, the boom-type installation method will result in the electric box being located too high in the east wind, which is not convenient for manual maintenance. Therefore, an electric box is needed that can reduce the humidity and temperature in the electric box and is convenient for daily manual maintenance. Utility Model Content

[0004] The main purpose of the utility model is to provide a boom-type dry-type transformer electric box suitable for a basement, which solves the problem that the temperature and humidity inside the transformer box in the basement are too high and the boom-type electric box is located too high and is inconvenient for maintenance.

[0009] In the preferred embodiment, a plurality of upper air holes are provided between the upper part of the box body and the heat dissipation ceiling, and an upper air conditioning filter is provided above the upper air holes to prevent the backflow of moisture in the heat dissipation ceiling;

[0027] In a preferred embodiment, a temperature sensor 116 and a humidity sensor 117 are provided inside the box 101 .

[0028] In a preferred embodiment, a bottom plate is provided between the box body 101 and the heating wire 114 , a plurality of penetrating lower air holes 115 are provided on the bottom plate, and a fan 122 is arranged below the heating wire 114 .

[0029] In a preferred embodiment, a lower air conditioning filter is provided below the fan 122 for filtering moisture and dust in the air entering the interior of the box body 101 .

[0030] In the preferred embodiment, a plurality of upper air holes 118 are provided between the upper portion of the box body 101 and the heat dissipation ceiling 102, and an upper air conditioning filter 119 is provided above the upper air holes 118 to prevent the moisture in the heat dissipation ceiling 102 from flowing back;

[0031] In the preferred embodiment, the interior of the heat dissipation ceiling 102 is a hollow structure, and a plurality of ceiling air inlet holes 120 are provided between the heat dissipation ceiling 102 and the upper air conditioning filter element 119;

[0032] The heat dissipation ceiling 102 is arranged in an inverted V shape on the top of the box body 101 , and a ceiling air outlet 121 is provided at the lower outer side of the heat dissipation ceiling 102 .

[0033] In the preferred embodiment, a box base 113 is further provided below the box 101;

[0034] A hanger support rod 104 is provided below the hanger 103 . The hanger support rod 104 penetrates the heat dissipation ceiling 102 and the box body 101 and is connected to the box body base 113 through threads.

[0035] In a preferred embodiment, a door 105 is provided on one side of the box body 101 , and a rotatable ladder hook 112 is provided on the other side. The ladder hook 112 is used to hang a telescopic ladder 124 .

[0036] In the preferred embodiment, a flip bracket 106 is further provided at the bottom of the box 101, and a telescopic ladder 124 is arranged between the flip brackets 106;

[0037] In the preferred embodiment, the telescopic ladder 124 includes a telescopic guide rod 107, one end of which is rotatably connected to the flip bracket 106, and a support frame 108 is provided below the other end;

[0039] The working principle of a boom-type dry-type transformer electric box suitable for a basement is as follows: the hanger 103 above the box 101 is connected to the top wall by expansion bolts to complete the installation. The electric box is provided with a temperature sensor 116 and a humidity sensor 117. When the temperature sensor 116 and the humidity sensor 117 sense that the temperature and humidity inside the box 101 exceed the threshold, the information processing module can be used to upload the information to the control system to alert the monitoring personnel. In the automatic mode, the fan under the box 101 will be started to cool down. When the humidity exceeds the standard, the wind generated by the fan is slightly heated by the electric heating wire 114, and the inside of the box 101 is properly dried to reduce the humidity inside the box 101.

[0040] The heat dissipation ceiling 102 on the top can prevent water droplets from the top of the wall from dripping onto the top of the electric box 101.

[0041] When manual maintenance is required on the electric box 101, it is not convenient for maintenance personnel to perform maintenance at a high place because the overall position of the electric box is a certain distance from the ground. If the hanging height is not high, the telescopic ladder 124 can be removed. When it is not convenient for maintenance, the ladder hook 112 needs to be opened, and the telescopic ladder 124 needs to be opened and extended to support on the ground. The maintenance personnel step on the ladder board to the front of the electric box to perform maintenance on the internal dry-type transformer.
