Description

Technical Field

[0001] The utility model relates to the field of ring network cabinets, and in particular to a ring network cabinet used for electrical automation. Background Art

[0002] Ring main unit is a group of electrical equipment (high voltage switchgear) installed in a metal or non-metallic insulated cabinet or made into an assembled interval ring main unit. Its core part uses load switches and fuses, which have the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises and other load centers.

[0003] At present, most ring network cabinets are equipped with multiple equally distributed voltage regulators. The voltage regulators will generate a certain amount of heat during actual operation. Therefore, most of them are equipped with corresponding heat dissipation components to blow air to dissipate heat inside the voltage regulator. However, in the actual heat dissipation process of traditional voltage regulators, since the heat dissipation position of the heat dissipation components installed on them is relatively fixed, the heat dissipation effect is better for the space close to the heat dissipation components in the voltage regulator, while the heat dissipation effect for the local space far away from the heat dissipation components in the voltage regulator will be correspondingly poor. Therefore, we make improvements on this and propose a ring network cabinet for electrical automation. Utility Model Content

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] In the solution of the utility model:

[0025] By setting up the swing component and the diverter pipe, the air drawn into the heat dissipation component is diverted and blown in different directions through the diverter pipe, so that it can fully contact the internal space of the voltage regulator to achieve a fast and uniform blowing and heat dissipation effect.

[0044] See also Figures 1 to 6 The utility model provides a technical solution: a ring network cabinet for electrical automation, comprising a cabinet body 1 and a voltage regulator 2 installed in the cabinet body 1, a plurality of voltage regulators 2 are arranged in the cabinet body 1 at equal intervals, a fixing plate 3 is installed on the front of the voltage regulator 2, and further comprising: a drainage pipe 4 connected to the interior of the voltage regulator 2 and connected to the fixing plate 3, a heat dissipation component 5 arranged on the outside of the voltage regulator 2 and connected to the fixing plate 3 for conveying air in the drainage pipe 4, a shunt pipe 6 connected to one end of the drainage pipe 4 away from the heat dissipation component 5, and a swing component 7 connected to the drainage pipe 4 for driving a plurality of shunt pipes 6 to swing back and forth to form a change in the heat dissipation air duct;

[0045] The heat dissipation assembly 5 includes a heat dissipation fan 51 and a support frame 52. The support frame 52 is fixed to the outside of the voltage regulator 2 for supporting and installing the heat dissipation fan 51 therein;

[0046] The swing assembly 7 includes a transmission shaft 71 rotatably connected to the end of the drainage tube 4 and a driving wheel 73 fixed to the surface of the transmission shaft 71 and meshed with the outer transmission wheel 72 thereof, wherein a plurality of driving wheels 73 are equidistantly distributed along the circumferential direction of the transmission wheel 72 and are rotatably connected to a swing arm 1 74, and one end of the swing arm 1 74 is hingedly connected to a swing arm 2 75 connected to the shunt tube 6, and a stabilizing plate 76 is movably connected to the inner side of the swing arm 2 75, and a slide seat 77 for the stabilizing plate 76 to slide is also connected to the shunt tube 6;

[0047] The drainage tube 4 includes a Y-shaped pipeline 41, a filter pipeline 42 and an output pipeline 43, which are connected end to end in sequence to form a drainage channel.

[0048] A drive motor 79 connected to a meshing wheel 78 is fixedly provided on the inner side of the output pipeline 43, and the meshing wheel 78 meshes with the transmission shaft 71 extending into the output pipeline 43. The drive motor 79 is a servo motor, which can control the speed and has a very accurate position accuracy. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque, thereby satisfying the bidirectional rotation of the drive motor 79;

[0049] The shunt pipe 6 includes a corrugated hose 61 connected to the output pipeline 43 and a shunt end 62 connected to one side of the corrugated hose 61. A plurality of corrugated hoses 61 are distributed in an annular manner on the outside of the output pipeline 43 and communicate with the inside thereof, and one end of the second swing arm 75 is hinged to the outside of the corresponding shunt end 62.

[0050] When the heat dissipation fan 51 in the heat dissipation component is started to transport external air into the voltage regulator 2, the air passes through the Y-shaped pipeline 41, the filter pipeline 42 and the output pipeline 43 and is finally discharged through the diversion end 62 on the corrugated hose 61. By setting a plurality of diversion ends 62, the air output from the heat dissipation component 5 can be dispersed at different positions, so that it can be better dispersed in the space inside the voltage regulator to form a better heat dissipation effect;

[0051] During the above-mentioned process of blowing and cooling, the driving motor 79 is started, so that the transmission shaft 71 at its output end drives the transmission wheel 72 and multiple driving wheels 73 meshing on its outer side to rotate. When the driving wheel 73 rotates in a circle, the swing arm 1 74 connected thereto will also rotate with it, and the swing arm 2 75 is guided by the stabilizing plate 76 on the slide 77, so the swing arm 75 will drive the diverter end 62 to swing back and forth. Through the reciprocating movement of the diverter end 62, the air can be diffused in different directions during the heat dissipation process, further improving the heat dissipation effect of the air inside the voltage regulator 2.

[0052] As a further optimization of this embodiment: the filter pipeline 42 includes a connecting pipe 420 and filter screens 421 arranged on both sides of the connecting pipe 420, and a cleaning brush 422 is also arranged in the connecting pipe 420 and is attached to the inner side of the filter screen 421. When air passes through the filter pipeline 42, the filter screen 421 arranged therein can block particulate matter in the air, thereby improving the quality of air entering the voltage regulator during heat dissipation, reducing the input of dust, and facilitating the clean and stable operation of the voltage regulator. The surfaces of the two cleaning brushes 422 are commonly connected with a drive shaft 423 for transmission connection with one end of the transmission shaft 71, and a dust collecting groove 424 is formed on the inner side of the connecting pipe 420 between the two filter screens 421;

[0053] When the driving motor 79 starts to drive the transmission shaft 71 to rotate, the transmission shaft 71 synchronously drives the cleaning brush 422 on the driving shaft 423 to rotate on the surface of the filter 421 , and the dust on the surface of the filter 421 can be cleaned by the rotation of the cleaning brush 422 .

[0054] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
