Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dry-type transformers, in particular to a one-machine multi-purpose intelligent dry-type transformer. BACKGROUND

[0002] In the process of operation of the dry-type transformer, the heat generated by the dry-type transformer is mainly from two aspects. One is the heat generated by the winding and the core loss. The inherent impedance of the winding generates electrical energy loss when the current passes through. This part of the loss is mainly released to the surrounding environment in the form of heat. The reasons for the overheating of the winding may include oil channel blockage, poor oil flow leading to ineffective cooling of turn insulation, and turn-to-turn (segment-to-segment) short circuit caused by insulation shedding and partial copper exposure. The magnetic resistance of the core generates hysteresis loss and eddy current loss when the magnetic field changes. These losses are also released in the form of heat. The temperature of the core is usually lower than that of the winding, but it is still one of the important heat sources of the dry-type transformer. The other is the heat generated by the insulation medium loss. When the insulation medium is subjected to an electric field, heat is generated due to the insulation medium loss, causing the temperature of the insulation medium to continuously rise. The insulation resistance of the insulation medium decreases with the rise in temperature, further exacerbating the generation of heat.

[0003] However, the heat sources described above need to be cooled by equipping a cooling mechanism to maintain the normal operation of the dry-type transformer. The dry-type transformer is mainly cooled by air cooling and air cooling. In some large power consumption places such as rail transit, factories, hospitals, and new energy power plants, a large number of dry-type transformers are equipped to form a transformer module, which needs to be accommodated in a professional power distribution room for operation. However, the heat generated by multiple groups of transformers cannot be converted and utilized, resulting in waste of this part of energy. In addition, in hot areas or during the summer high temperature period, the transformer module cannot meet its cooling demand by relying solely on air cooling and air cooling, and the transformer is prone to damage. Therefore, we propose a one-machine multi-purpose intelligent dry-type transformer that can fully utilize and efficiently cool the operating heat. SUMMARY

[0004] The present application aims to provide a one-machine multi-purpose intelligent dry-type transformer to solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a one-machine multi-purpose intelligent dry-type transformer, comprising a dry-type transformer main body, a fixed seat fixedly connected to the bottom side of the dry-type transformer main body, a plurality of evenly distributed cooling fans fixedly installed on the fixed seat, and three groups of electromagnetic windings provided on the dry-type transformer main body, wherein the cooling fans correspond to each group of electromagnetic windings.

[0006] The heat dissipation fan is symmetrically arranged on both sides of the dry-type transformer body, and a multifunctional pipeline module is communicated with one side of the heat dissipation fan away from the dry-type transformer body, wherein the multifunctional pipeline module comprises a main pipeline for outputting heat of the dry-type transformer body or inputting cold air. The multifunctional pipeline module is used for multi-stage output of heat or input of cold air of the dry-type transformer body, and can freely switch the output of heat and the input of cold air of the dry-type transformer body.

[0007] Further, the heat dissipation fan comprises a motor, an impeller, a shell, an air outlet shell and an air inlet shell, the uniformly distributed shells are fixedly installed on the fixing seat, the motor is fixedly installed on one side of the shell, the output end of the motor is fixedly connected with the impeller, the impeller is arranged on the inner side of the shell, the other end of the shell is rotationally connected with the inner wall of the shell through a rotating shaft, two air inlets are arranged on the shell, the air outlet shell is communicated with the upper side of the air inlet close to the electromagnetic winding, and the air inlet close to the main pipeline is communicated with the air inlet shell. Further, two notches are formed in the air outlet shell, one notch corresponds to the inner side of the dry-type transformer body, and the other notch corresponds to the outer side of the dry-type transformer body.

[0008] Further, the multifunctional pipeline module comprises an output heat module, the output heat module comprises a communication structure and a branch assembly, the communication structure is communicated with the main pipeline, and the branch assembly is communicated with the communication structure.

[0009] When it is in the hot season or in a high-temperature area, cold air can be input through the main pipeline or the branch pipeline, at the same time, the motor is started in reverse, so that the air force from the air inlet shell to the air outlet shell is generated, the cold air is guided by the air force, and can directly act on the inner side and the outer side of the dry-type transformer body to perform efficient cooling, thereby solving the problem that the external temperature is high, the dry-type transformer body has poor heat dissipation effect and affects the operation. Further, the communication structure comprises a connecting pipe, a communication shell, an electromagnetic valve one and a through pipe, the communication shell is communicated with one side of the air inlet shell away from the shell, the connecting pipe is communicated with one side of the communication shell away from the air inlet shell, the through pipe is arranged on the upper side of the connecting pipe, the lower end of the through pipe is communicated with the three connecting pipes, the electromagnetic valve one is communicated with the through pipe, and the electromagnetic valve one corresponds to the connecting pipe.

[0010] When the dry-type transformer main body is in normal operation, the motor is started, and the motor output end drives the impeller fixedly connected thereto to rotate, thereby generating air flow from the air outlet shell to the air inlet shell. Since the air outlet shell is provided with two notches corresponding to the inner side and the outer side of the electromagnetic winding, the heat of the electromagnetic winding is partitioned and extracted, and the air flow with heat enters the communication shell through the air inlet shell, and then enters the connecting pipe; Further, the branch assembly includes two branch pipes and electromagnetic valves, and the connecting pipe is communicated with the branch pipe away from the communication shell, and the branch pipe is communicated with the second electromagnetic valve.

[0011] One end of the branch pipe is communicated with an external flow channel, which can be connected to equipment and scenes that need heat (for example, equipment needs to be preheated, and processing equipment needs heat). By controlling the opening and closing of the first electromagnetic valve, the second electromagnetic valve and the third electromagnetic valve, heat can be introduced into the branch pipe.

[0012] Further, the main pipe is fixedly installed with uniformly distributed third electromagnetic valves, the third electromagnetic valves correspond to adjacent connecting pipes, and the third electromagnetic valves are used to control the opening or closing of the passages between the connecting pipes.

[0013] Further, the connecting pipe is also fixedly installed with a temperature detection assembly, the temperature detection assembly includes a branch pipe and a temperature sensor, the upper side of the connecting pipe is communicated with the branch pipe, and the temperature sensor is fixedly installed on the branch pipe.

[0014] The temperature sensor can detect the temperature of the heat flow in each connecting pipe. Through the detection data, the temperature of the heat flow in each connecting pipe can be obtained. According to the corresponding temperature requirement, the heat is circulated to another connecting pipe through the serial pipe, the temperature is superimposed, and then the heat flow after temperature superposition is supplied to the external flow channel through the branch pipe, for use, thereby realizing the purpose of multi-stage output of heat. Further, the multifunctional module further includes an input cold air module, the input cold air module includes a condensing assembly, the condensing assembly includes a pipe joint, an air guide shell and a condensing pipe, the air inlet shell is communicated with the air guide shell away from the shell, the air guide shell is provided with uniformly distributed condensing pipes on one side, the air guide shell corresponds to the condensing pipe, and the two ends of the condensing pipe are communicated with the main pipe through the pipe joint.

[0015] When greater heat dissipation is required, the connecting structure and branch components are replaced with condensing components, and then refrigerant is introduced into the main pipeline through an external refrigeration device and circulated, so that the refrigerant circulating in the condenser tube quickly reduces the ambient temperature. At this time, the motor is started to reverse, so that wind force is generated from the air inlet shell to the air outlet shell, and then the cold air around the air guide shell flows through the condenser tube to the inner and outer sides of the dry-type transformer body, achieving high-intensity heat dissipation.

[0016] Compared with the prior art, the present invention provides a multi-purpose intelligent dry-type transformer with the following advantages: 1. This multi-purpose intelligent dry-type transformer, through the cooperation between the heat dissipation fan, main pipeline, branch components, and temperature detection components, can convert the heat generated by the dry-type transformer during operation in cold seasons for indoor heating. At the same time, it can also output heat according to the temperature requirements of the equipment and scenarios that require heat, realizing multi-level heat output, solving the problem that the heat generated by the existing dry-type transformer cannot be converted and utilized, resulting in the waste of this part of energy. Moreover, in hot seasons and high-temperature areas, the mode can be changed to input cold air to improve the heat dissipation effect, ensure the normal operation of the dry-type transformer, and achieve the effect of multi-purpose of one machine.

[0017] 2. This multi-purpose intelligent dry-type transformer, through the coordinated action of the cooling fan, main pipeline, and condensing assembly, can circulate the refrigerant to achieve high-intensity heat dissipation. This solves the problem of poor heat dissipation effect and short service life of the transformer in some special ultra-high temperature scenarios. In hot areas or high temperature periods in summer, the transformer module relies solely on air cooling and wind cooling, which cannot meet its heat dissipation needs and is prone to transformer damage.

[0018] 3. This multi-purpose intelligent dry-type transformer builds a pipeline network for heat output and cold air input below the dry-type transformer module and can freely switch the heat output and cold air input of the dry-type transformer body. At the same time, the pipeline network can be placed underground and will not occupy the ground space. The heat output and cold air input of each group of dry-type transformers are connected through the pipeline network, which can be used to uniformly manage the dry-type transformers and achieve the purpose of multi-group synchronous frequency management.
