Description

Technical Field

[0001] The invention relates to the field of transformers, in particular to a graded processing energy-saving transformer. Background Art

[0002] At present, transformers have been widely used in the power field. The transformers currently used generally use two cooling methods: air cooling and water cooling. However, when using them, the cooling of the transformer is often controlled only by changing the intensity of air cooling or water cooling. In this way, there is a situation where the transformer still cannot be cooled under the maximum cooling method, resulting in a waste of energy. In addition, for the water cooling of the transformer, the water cooling group is generally cooled by wind, which also causes a large amount of energy consumption. Summary of the invention

[0003] The object of the present invention is to provide a hierarchical processing energy-saving transformer to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hierarchical processing energy-saving transformer, comprising a transformer box, a transformer chamber is provided in the transformer box, a transformer body is detachably fixedly connected to the lower end wall of the transformer chamber, the transformer body can perform transformer work, two fans symmetrical up and down are fixedly provided at the rear end of the transformer chamber, the fans can be started to cool the transformer body, a liquid inlet pipe and a liquid outlet pipe are connected at the right end of the transformer body, the liquid outlet pipe can discharge the cooling water after absorbing heat in the transformer box, and the liquid inlet pipe can input the cooled cooling water into the transformer box, thereby dissipating heat in the transformer box;

[0005] A filter and a first one-way valve are fixedly provided on the right end wall of the transformer chamber, the liquid inlet pipe is connected to the filter, the liquid outlet pipe is connected to the first one-way valve, a mounting plate is fixedly connected to the right end face of the transformer box, an intermediate plate is fixedly connected to the front end wall of the mounting plate, a support plate is fixedly connected to the front end face of the intermediate plate, a temperature monitor and a first water pump are fixedly provided on the right end of the support plate, the temperature monitor is connected to the filter through a second connecting pipe, the first water pump is connected to the first one-way valve through a first connecting pipe, a short heat dissipation pipe is connected between the temperature monitor and the first water pump, a long heat dissipation pipe is connected to the right end of the temperature monitor and the first water pump, the two long heat dissipation pipes can be connected to the elbow pipes through two mounting rings, thereby realizing the connection between the two long heat dissipation pipes, and the long elbow pipe can be selected when the transformer needs to be strongly cooled, so that the cooling time of the coolant in the outside world is prolonged, and the first water pump can control the discharge of cooling water from the short heat dissipation pipe or the long heat dissipation pipe, thereby corresponding to different transformer cooling temperatures, saving energy.

[0006] The two long heat dissipation tubes are both fixedly connected with cooling tubes, and the two cooling tubes can be connected to the same intermediate tube through a connecting ring, thereby realizing the replacement of the length of the intermediate tube.

[0007] A second water pump is fixedly provided on the mounting plate, and an inflow pipe is provided in communication with the second water pump and the rear end of the second water pump is provided with an access pipe, through which external cold water can be drawn through the access pipe and discharged into the cooling pipe on the upper side through the inflow pipe, so as to cool the cooling water in the long heat dissipation pipe, and the energy for cooling the cooling water through ventilation is saved by cooling with cold water.

[0008] The mounting plate is fixedly provided with a second one-way valve, the second one-way valve is connected to the cooling pipe at the lower side and is provided with an outflow pipe, the rear end of the second one-way valve is connected to a discharge pipe, the second one-way valve limits water from moving only from the outflow pipe to the discharge pipe, and the cold water that absorbs heat in the cooling pipe at the lower side can be discharged through the outflow pipe, the second one-way valve and the discharge pipe.

[0009] The first one-way valve restricts the liquid from moving only from the pressure transformer to the first water pump.

[0010] The filter can filter the cooling water discharged from the second connecting pipe, thereby preventing the cooling water from containing impurities that affect the cooling function.

[0011] After the bent pipe is disassembled, the cooling water can be replaced through the upper and lower cooling pipes.

[0012] A cabinet door capable of shielding the transformer body is hingedly connected to the front end of the transformer chamber, and a plurality of through holes for wiring are arranged on the rear end wall of the transformer chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention can cool the transformer in the transformer cavity by air by starting the fan device, thereby avoiding the potential safety hazard caused by heat accumulation in the transformer. The present invention can also extract cooling water from the transformer when the temperature of the transformer is high by arranging a liquid outlet pipe, a first one-way valve, a first connecting pipe and a first water pump, and inject the cooling water back into the transformer through the liquid inlet pipe after natural cooling through the short heat dissipation pipe, thereby taking away the heat in the transformer through the cooling water.

[0015] The filter can filter the cooling water to prevent the impurities in the cooling water from affecting the heat dissipation. The temperature monitor can monitor the temperature of the cooling water before it is injected into the transformer. When the cooling water temperature is too high and the short heat dissipation pipe cannot dissipate the heat completely, the first water pump is started to dissipate the heat over a long distance through the long heat dissipation pipe and the elbow. The installation ring can replace a longer elbow to meet different heat dissipation requirements.

[0016] In addition, when the temperature of the transformer is too high and the natural heat dissipation of the cooling water cannot achieve the desired effect, the second water pump injects external cold water into the cooling pipe, exchanges heat with the cooling water passing through the long heat dissipation pipe and the curved pipe, and uses the cold water to dissipate the heat of the cooling water, thereby avoiding the energy consumption caused by using a fan to dissipate the heat of the cooling water. After the cold water receives the heat, it can be used, which also saves energy. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1-6 The present invention provides a technical solution: a hierarchical processing energy-saving transformer, comprising a transformer box 101, wherein a transformer chamber 102 is provided in the transformer box 101, and a transformer body 103 is detachably fixedly connected to the lower end wall of the transformer chamber 102, and the transformer body 103 can perform a transformer operation, and two fans 131 symmetrical up and down are fixedly provided at the rear end of the transformer chamber 102, and the fans 131 can be started to cool the transformer body 103, and a liquid inlet pipe 117 and a liquid outlet pipe 104 are connected at the right end of the transformer body 103, and the liquid outlet pipe 104 can discharge the cooling water after absorbing heat in the transformer box 101, and the liquid inlet pipe 117 can input the cooled cooling water into the transformer box 101, thereby dissipating heat in the transformer box 101;

[0027] The right end wall of the transformer chamber 102 is fixedly provided with a filter 116 and a first one-way valve 105, the liquid inlet pipe 117 is connected to the filter 116, the liquid outlet pipe 104 is connected to the first one-way valve 105, the right end face of the transformer box 101 is fixedly connected with a mounting plate 118, the front end wall of the mounting plate 118 is fixedly connected with an intermediate plate 119, the front end face of the intermediate plate 119 is fixedly connected with a support plate 121, the right end of the support plate 121 is fixedly provided with a temperature monitor 113 and a first water pump 107, the temperature monitor 113 is connected to the filter 116 through a second connecting pipe 115, the first water pump 107 is connected to the first one-way valve 105 through a first connecting pipe 106. A short heat dissipation pipe 114 is provided between the temperature monitor 113 and the first water pump 107, and a long heat dissipation pipe 112 is provided between the temperature monitor 113 and the right end of the first water pump 107. The two long heat dissipation pipes 112 can be connected to each other through two mounting rings 125 and an elbow 126, thereby realizing the connection between the two long heat dissipation pipes 112. When the transformer needs to be strongly cooled, the long elbow 126 can be selected to extend the cooling time of the coolant in the outside world. The first water pump 107 can control the discharge of cooling water from the short heat dissipation pipe 114 or the long heat dissipation pipe 112, thereby corresponding to different transformer cooling temperatures and saving energy.

[0028] The two long heat dissipation tubes 112 are both fixedly connected with a cooling tube 108 . The two cooling tubes 108 can be connected to the same intermediate tube 111 via a connecting ring 109 , thereby realizing the replacement of the length of the intermediate tube 111 .

[0029] The mounting plate 118 is fixedly provided with a second water pump 123, and the second water pump 123 is connected to the upper cooling pipe 108 by an inflow pipe 122. The rear end of the second water pump 123 is connected by an access pipe 124. External cold water can be drawn through the access pipe 124 through the inflow pipe 122 and discharged into the upper cooling pipe 108 through the inflow pipe 122, so as to cool the cooling water in the long heat dissipation pipe 112. The cooling of the cold water saves the energy for cooling the cooling water through ventilation.

[0030] The mounting plate 118 is fixedly provided with a second one-way valve 127, and the second one-way valve 127 is connected to the lower cooling pipe 108 and is provided with an outflow pipe 129. The rear end of the second one-way valve 127 is connected with a discharge pipe 128. The second one-way valve 127 limits water to move only from the outflow pipe 129 to the discharge pipe 128. The cold water that absorbs heat in the lower cooling pipe 108 can be discharged through the outflow pipe 129, the second one-way valve 127 and the discharge pipe 128.

[0031] The first one-way valve 105 limits the liquid to move only from the pressure transformer 103 to the first water pump 107 .

[0032] The filter 116 can filter the cooling water discharged from the second connecting pipe 115 to prevent the cooling water from containing impurities that affect the cooling function.

[0033] After the bent pipe 126 is disassembled, the cooling water can be replaced through the upper and lower cooling pipes 108 .

[0034] A cabinet door capable of shielding the transformer body 103 is hingedly connected to the front end of the transformer chamber 102 , and a plurality of through holes for wiring are arranged on the rear end wall of the transformer chamber 102 .

[0035] Working principle:

[0036] When in use, the transformer box 101 is moved to the plane where it needs to work, and then the external line is connected through the through hole on the rear side of the transformer chamber 102 and connected to the transformer 103. At this time, the transformer 103 can perform the transformer work, and the heat generated by the transformer 103 during the transformer operation is started and taken away by the fan 131.

[0037] If the temperature of the transformer 103 rises due to work or other reasons, and the fan 131 alone cannot dissipate heat, the first water pump 107 is started to extract cooling water from the transformer 103 through the first connecting pipe 106, the first non-return valve 105 and the liquid outlet pipe 104, and the cooling water is discharged to the temperature monitor 113 through the short heat dissipation pipe 114. After the temperature is detected by the temperature monitor 113, the cooling water enters the filter 116 through the second connecting pipe 115. The filter 116 filters the cooling water and then discharges it to the transformer 103 through the liquid inlet pipe 117. Through this cycle, the cooling water is externally cooled, and the heat in the transformer 103 is taken away by the circulation of the cooling water to complete the heat dissipation.

[0038] If the temperature of the cooling water detected by the temperature monitor 113 is still high after the heat is dissipated by the short heat dissipation pipe 114, the temperature monitor 113 starts the first water pump 107, so that the first water pump 107 discharges liquid to the temperature monitor 113 through the long heat dissipation pipe 112 and the elbow 126, thereby making the cooling water travel a longer distance in the outside world, which can dissipate more heat, and the length of the intermediate pipe 111 and the elbow 126 can be lengthened through the connecting ring 109 and the mounting ring 125, which can dissipate more heat;

[0039] If the cooling water temperature cannot be lowered at the temperature monitor 113 by natural heat dissipation, the second water pump 123 is started to connect the pipe 124 to inject external cold water into the cooling pipe 108 through the inlet pipe 122, and the water is discharged through the outlet pipe 129, the second one-way valve 127 and the outlet pipe 128. The heat dissipation of the cooling water is completed by the temperature exchange between the cold water and the cooling water, thus saving energy for heat dissipation by wind power, and the hot water generated after the cold water absorbs heat can also be used.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
