Description
技术领域technical field
本发明涉及电气工程设备技术领域,具体是一种户外用散热JP柜。The invention relates to the technical field of electrical engineering equipment, in particular to an outdoor cooling JP cabinet.
背景技术Background technique
JP柜是指用于低压配电系统的补偿配电柜,一般安装在变压器的下方。JP柜是为适应农村低压配电装置标准化、小型化、户外式的要求而设计的,它集配电、计量、保护(过载、短路、漏电、防雪)、电容无功补偿于一体。JP柜内部安装了大量的电器元件,随着电流的作用,电器元件在工作的过程中会产生热量;在用电高峰期的时候,众多的电气元件同时工作会导致柜内部的温度快速升高,进而增加柜内过热起火的风险。当处于用电低峰期的时候,各电器元件工作功率降低,此时柜体内部的温度较低,对电气元件没有干扰。JP cabinet refers to the compensation distribution cabinet used for low-voltage power distribution system, which is generally installed under the transformer. JP cabinet is designed to meet the standardization, miniaturization and outdoor requirements of rural low-voltage power distribution equipment. It integrates power distribution, measurement, protection (overload, short circuit, leakage, snow prevention), and capacitor reactive power compensation. A large number of electrical components are installed inside the JP cabinet. With the action of current, the electrical components will generate heat during the working process; during the peak period of power consumption, many electrical components work at the same time, which will cause the temperature inside the cabinet to rise rapidly. , thereby increasing the risk of overheating and fire in the cabinet. When it is in the low peak period of electricity consumption, the working power of each electrical component is reduced. At this time, the temperature inside the cabinet is low, and there is no interference to the electrical components.
为了降低柜体内部的温度,一般在JP柜的两侧开设散热窗,进而使柜体的内部形成气流回路,通过空气的流动带走柜体内部产生的热量。但是柜体两侧开设的散热窗较小,导致气流量也偏小,进而无法快速将处于用电高峰期的柜体内的温度降低到安全范围之内。有的JP柜上开设有较大的散热窗,能够进行快速的散热,但是当用电量正常的时候,无法缩小窗口,这样会导致一些垃圾容易进入柜体内部,进而破坏内部电气元件。In order to reduce the temperature inside the cabinet, heat dissipation windows are generally set up on both sides of the JP cabinet, so that an airflow loop is formed inside the cabinet, and the heat generated inside the cabinet is taken away by the flow of air. However, the heat dissipation windows on both sides of the cabinet are small, resulting in a relatively small air flow, which makes it impossible to quickly reduce the temperature in the cabinet during the peak period of power consumption to a safe range. Some JP cabinets have larger heat dissipation windows, which can quickly dissipate heat, but when the power consumption is normal, the windows cannot be reduced, which will cause some garbage to easily enter the cabinet and damage the internal electrical components.
面对上述技术问题,亟需一种可以克服上述技术问题的散热JP柜。Facing the above-mentioned technical problems, there is an urgent need for a heat-dissipating JP cabinet that can overcome the above-mentioned technical problems.

与现有技术相比,本发明的有益效果是:Compared with prior art, the beneficial effect of the present invention is:
1、本发明在柜体的两侧开始有总面积占比较大的进气孔,从而加大柜体内部的进气量,进而提高柜体内部温度的下降速率。侧板能够在驱动部的作用下转动,从而控制进气孔的开合,进而在柜体内部温度较高的时候开启进气孔进行散热,以及在外界雨量较大的时候关闭进气孔避免雨水进入柜体内部。在柜体顶部设置的排气孔,能够与进气孔形成气流回路,加快柜体内部的散热效率。顶棚的设计,能够避免雨水进入排气孔,从而在散热的同时确保柜体内部不会侵入雨水。1. In the present invention, there are air intake holes with a larger total area on both sides of the cabinet body, thereby increasing the air intake inside the cabinet body, and further increasing the temperature drop rate inside the cabinet body. The side plate can be rotated under the action of the driving part, so as to control the opening and closing of the air intake hole, and then open the air intake hole for heat dissipation when the internal temperature of the cabinet is high, and close the air intake hole when the external rainfall is large to avoid Rainwater enters the interior of the cabinet. The exhaust hole set on the top of the cabinet can form an airflow circuit with the air intake hole to speed up the heat dissipation efficiency inside the cabinet. The design of the ceiling can prevent rainwater from entering the vent hole, so as to dissipate heat while ensuring that rainwater will not intrude into the cabinet.
2、本发明的两块侧板布置在柜体的两侧,并且铰接轴位于柜体的同一条对角线上,这样在驱动电机的作用下,能够沿同一时针方向同步打开或者同步关闭,这样两块侧板与对应侧面之间形成的V型槽的槽口方向相反,进而可以吸入不同方向的风。当柜体的前面或者是后面有风时,风会从槽口与风向向对的侧板处进入柜体内,再由另一侧的进气孔和或顶部的排气孔排出,这样柜体内部可以进入多个方向的风,从而提高柜体的散热效率。2. The two side plates of the present invention are arranged on both sides of the cabinet body, and the hinge shafts are located on the same diagonal line of the cabinet body, so that under the action of the drive motor, they can be opened or closed synchronously in the same clockwise direction, In this way, the notches of the V-shaped grooves formed between the two side panels and the corresponding side surfaces have opposite directions, so that wind from different directions can be sucked in. When there is wind at the front or back of the cabinet, the wind will enter the cabinet from the side plate opposite the slot and the wind direction, and then be discharged from the air inlet on the other side and the exhaust hole on the top, so that the cabinet Wind from multiple directions can enter the interior, thereby improving the heat dissipation efficiency of the cabinet.
3、本发明使用的喇叭状的进气孔,能够压缩空气,调高空气的吸热效率,加快柜体内部的降温速度。并且向上倾斜设置的进气孔具有一定的防水功能,当雨量较小的时候,雨水会沿着柜体的侧面流下,不会进入柜体内部。在雨量较大的时候侧板关闭,一方面能够避免雨水进入柜体内,另一方面也可以避免过多的湿气进入柜体内,确保柜体内部电气元件的稳定工作。3. The trumpet-shaped air intake hole used in the present invention can compress air, increase the heat absorption efficiency of the air, and accelerate the cooling speed inside the cabinet. In addition, the air intake hole arranged upwards has a certain waterproof function. When the rainfall is small, the rainwater will flow down the side of the cabinet and will not enter the inside of the cabinet. When the rainfall is heavy, the side panels are closed. On the one hand, it can prevent rainwater from entering the cabinet, and on the other hand, it can also prevent excessive moisture from entering the cabinet, ensuring the stable operation of the electrical components inside the cabinet.
4、本发明使用带有导气孔的支撑板,能够使柜体内部的热量穿过导气孔进而上升到柜体顶部,并由排气孔排出。导气孔减少了对柜体内部空气流动的干扰,提高了柜体内部的热交换速率,进一步加快了降温的效率。4. The present invention uses a support plate with air guide holes, so that the heat inside the cabinet can pass through the air guide holes and then rise to the top of the cabinet body, and be discharged through the exhaust holes. The air guide holes reduce the interference to the air flow inside the cabinet, improve the heat exchange rate inside the cabinet, and further accelerate the cooling efficiency.
