Abstract
Description
Technical Field
[0001] This utility model belongs to the field of energy storage equipment technology, and in particular relates to a heat dissipation structure for the transformer chamber of an energy storage substation. Background Technology
[0002] Prefabricated energy storage substations, as compact power supply devices that combine high-voltage switchgear, transformers, and low-voltage switchgear, are widely used in modern power systems. The transformer room is a key component of the prefabricated energy storage substation, housing the core equipment: the transformer. During operation, the transformer plays a crucial role in converting the input high voltage into a low voltage suitable for the energy storage system and low-voltage loads. Its stable operation is essential for ensuring the effective conversion, transmission, and distribution of electrical energy throughout the entire prefabricated energy storage substation system.
[0003] When a transformer is operating, energy losses, such as core losses and winding resistance losses, are converted into heat. If this heat cannot be dissipated effectively and promptly, the transformer oil temperature will rise. Excessively high oil temperatures accelerate the aging of insulation materials, reduce insulation performance, and in severe cases, may cause insulation breakdown, affecting the transformer's lifespan and operational reliability. Furthermore, excessively high temperatures can reduce the transformer's load capacity, affecting its normal voltage transformation and energy transmission functions, thus adversely impacting the entire energy storage system and its connected loads. Therefore, ensuring the transformer operates within a suitable temperature range, i.e., ensuring good heat dissipation, is a key consideration in the design, operation, and maintenance of transformer rooms.
[0004] Existing heat dissipation solutions for transformer rooms in energy storage substations include natural ventilation, which is unsuitable for high-temperature and high-humidity environments, and forced ventilation. While forced ventilation can improve heat dissipation, it also increases energy consumption and introduces dust and other pollutants, affecting the long-term stability of the equipment. Therefore, an economical and environmentally friendly heat dissipation method is needed to improve the heat dissipation effect of transformer rooms in energy storage substations. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a heat dissipation structure for the transformer chamber of an energy storage transformer substation, so as to solve the problem of poor heat dissipation effect for the transformer chamber of an energy storage transformer substation in the prior art.
[0006] The basic solution provided by this utility model is: a heat dissipation structure for a transformer room of an energy storage box-type substation, including a box body, a detection device, a control device and a heat dissipation device. A baffle plate is provided along the box wall inside the box body. The baffle plate divides the inside of the box body into upper and lower connected areas in the middle. An air inlet is provided in the area below the baffle plate inside the box body, and an air outlet is provided in the area above the baffle plate inside the box body.
[0007] The detection device includes a temperature detection module and a humidity detection module; the control device includes a controller; and the heat dissipation device includes an air inlet module and an air outlet module, with the air inlet module located at the air inlet and the air outlet module located at the air outlet.
[0008] The temperature detection module, humidity detection module, air inlet module, and air outlet module are all electrically connected to the controller. The temperature detection module and humidity detection module are used to detect the temperature and humidity values inside the chamber and generate temperature and humidity signals, which are transmitted to the controller. The controller is used to control the operating status of the air inlet module and the air outlet module based on the temperature and humidity signals.
[0009] Furthermore, the wind baffle is provided in four pieces, which are fixed to the inner wall of the box by reinforcing plates. The area enclosed by the four wind baffles is a connected area in the middle, and the transformer room equipment is arranged directly below the connected area.
[0010] Furthermore, the control device also includes a timing module, which is electrically connected to the controller. The controller is also used to control the timing module to perform timing processing when controlling the operating status of the air inlet module and the air outlet module. The controller is also used to control the operating status of the air inlet module and the air outlet module according to the temperature signal and humidity signal after the timing processing is completed.
[0011] Furthermore, it also includes a warning device, which is electrically connected to the controller. The controller is also used to control the warning device to issue a warning signal based on temperature and humidity signals.
[0012] Furthermore, the warning device includes either a warning light or a buzzer.
[0013] The principle and advantages of this utility model are as follows: In this solution, a baffle plate is first installed in the box of the energy storage transformer room. The baffle plate is installed along the inner wall of the box, thereby dividing the inner part of the box into an upper area and a lower area. An air outlet is installed in the upper area of the box, and an air inlet is installed in the lower area of the box. An air outlet module is arranged at the air outlet, and an air inlet module is arranged at the air inlet. At the same time, the upper area and the lower area are connected, so that the airflow between the upper area and the lower area can flow.
[0014] After setup, the equipment components inside the transformer room are arranged directly below the connecting area. Therefore, due to the baffle plate and the heat generated by the equipment components during operation, the cold air blown into the box from the air inlet module at the air inlet circulates in the lower area of the box due to the baffle plate, then moves from the connecting area to the upper area, and finally exits from the air outlet. In this way, the cold air blown into the box from the air inlet module can carry away more of the heat generated by the equipment components, thereby improving the heat dissipation effect inside the box.
[0015] Furthermore, in order to improve the intelligence of the heat dissipation function, this application implements real-time monitoring and prompting functions for indoor heat dissipation of the energy storage transformer by setting up detection devices, control devices, and warning devices.

[0019] The following detailed description illustrates the specific implementation method:
[0020] The markings in the accompanying drawings of the instruction manual include: 1. Box body, 2. Baffle plate, 3. Air inlet, and 4. Air outlet.
[0021] The basic implementation examples are as follows: Figure 1 and Figure 2 The diagram shows a heat dissipation structure for the transformer chamber of an energy storage transformer substation, comprising a housing 1, a detection device, a control device, and a warning device. The energy storage transformer substation is composed of an energy storage chamber, a transformer chamber, a measurement and control chamber, and a high-voltage chamber. In this application, the housing 1 refers to the housing 1 of the transformer chamber of the energy storage transformer substation. Inside the housing 1, wind baffles 2 are provided along the housing wall. Specifically, the wind baffles 2 are set in different shapes according to the shape of the housing 1. For example, if the housing 1 is a rectangular housing 1, then in this embodiment, four wind baffles 2 are set and sequentially spliced along the inner wall of the rectangular housing 1. Thus, the wind baffles 2 divide the inner wall of the housing 1 into upper and lower regions. At the same time, the middle of the area enclosed by the wind baffles 2 is in a connected state, allowing air to circulate between the upper and lower regions.
[0022] To improve ventilation and heat dissipation within the enclosure 1, an existing intelligent ventilation system is utilized. Specifically, the heat dissipation device includes an air inlet module and an air outlet module, the control device includes a controller, and the detection device includes a temperature detection module and a humidity detection module. First, an air outlet is opened in the upper area of the baffle plate 2, and an air inlet is opened in the lower area. The air inlet module is located at the air inlet, and the air outlet module is located at the air outlet. Temperature and humidity detection modules are installed inside the enclosure 1. These modules, along with the air inlet and air outlet modules, are electrically connected to the controller. When the temperature and humidity values detected by the temperature and humidity detection modules are converted into electrical signals and transmitted to the controller, the controller determines the high or low level of the electrical signals and adjusts the air inlet and air outlet modules accordingly. For example, if the controller receives the temperature and humidity signals and outputs a high-level signal, it indicates that the temperature or humidity value is too high and dehumidification is required. Therefore, the power of the air inlet module and the air outlet module are increased to quickly lower the temperature inside the enclosure 1.
[0023] However, existing intelligent ventilation systems have the problem that, although forced ventilation is effective, it consumes a lot of energy, which is not conducive to cost reduction and efficiency improvement for enterprises. In this regard, the baffle 2 set in this application, when the airflow for cooling, such as cold air, is blown in from the air inlet module of the lower area, according to the existing box 1, the cold air is immediately driven by the air outlet module and discharged from the box 1. This makes it impossible for the cold air generated by the air inlet module to carry away more heat, so that the air inlet module can only continuously generate cold air. However, the baffle 2 set in the box 1 in this application, when the cold air generated by the air inlet module flows to the upper area of the box 1, is blocked by the baffle 2 and circulates again in the lower area of the box 1. Since the heat dissipation parts of the equipment in the box 1 are all located in the lower area, the cold air generated by the air inlet module can circulate several times at the equipment to carry away more heat, resulting in better heat dissipation. Moreover, there is no need to add additional electrical control equipment, making it more economical and environmentally friendly.
[0024] In addition to the existing intelligent ventilation system, the control device in this application also includes a timer module and an alarm device. The timer module is electrically connected to the controller. Its function is to perform timed processing when the controller increases the power of the air inlet module and the air outlet module. If the temperature signal and humidity signal received by the controller are still high-level signals after the timed processing is completed, the controller will continue to control the operation of the air inlet module and the air outlet module. Otherwise, the control of increasing the power of the air inlet module and the air outlet module will be stopped, and the control will switch to stable control.
[0025] The warning device is also electrically connected to the controller to remind the user that the temperature or humidity value inside the cabinet 1 is too high. In this embodiment, the warning device is an alarm.
[0026] In addition, in this embodiment, the controller uses a microcontroller, the temperature detection module is a temperature sensor, the humidity detection module is a humidity sensor, the timing module is a timer built into the microcontroller, the air intake module is a cooler, and the air outlet module is an exhaust fan.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
