背景技术Background technique
新型高压环网柜内部空间十分紧凑，为保证其在高湿地区内部绝缘水平，保证其可靠工作，对柜内防潮、防凝露提出了更高的要求。The internal space of the new high-voltage ring network cabinet is very compact. In order to ensure its internal insulation level in high-humidity areas and ensure its reliable operation, higher requirements are put forward for moisture-proof and anti-condensation in the cabinet.
电气元件受潮，会存在问题包括：When electrical components are damp, there will be problems including:
1、电器设备生锈，导至转动部分在执行工作时失灵；1. The electrical equipment is rusted, causing the rotating parts to fail when performing work;
2、电器设备严重受潮后，容易造成电气击穿或绝缘下降，产生安全隐患；2. After the electrical equipment is severely damp, it is easy to cause electrical breakdown or insulation drop, resulting in potential safety hazards;
3、电器设备长期严重受潮，会使设备的电气连接处接触不良，在执行电气传动时发生设备拒动或乱动。3. The electrical equipment is seriously damp for a long time, which will cause the electrical connection of the equipment to be in poor contact, and the equipment will refuse to move or move indiscriminately during the implementation of electrical transmission.
因此，解决高压环网柜凝露问题，是保证电气元件设备正常运行必然条件。Therefore, solving the condensation problem of the high-voltage ring network cabinet is a necessary condition to ensure the normal operation of electrical components and equipment.
我国在开关柜中采用自动加热除湿控制器防止凝露已有十几年历史，这种加热除湿控制器在抗潮湿、防凝露保证高压设备可靠运行起到了积极作用，但在有的地区应用中也出现了一些问题。例如：在南方的梅雨季节，有时开关柜内部的空气湿度较高，甚至开关柜内局部已有结露现象，由于安装在柜体内部的凝露传感器位置并没有到达凝露的程度，或者凝露传感器长期受空气中灰尘和气体侵蚀，使传感器的灵敏度受到影响，凝露控制器不能及时地启动加热器，致使凝露控制的作用失灵，设备不能够正常运行，给开关设备的安全运行带来威胁。my country has used automatic heating and dehumidification controllers to prevent condensation in switch cabinets for more than ten years. This heating and dehumidification controller has played an active role in anti-humidity and anti-condensation to ensure the reliable operation of high-voltage equipment, but it is used in some areas. There were also some problems. For example: in the rainy season in the south, sometimes the air humidity inside the switch cabinet is high, and there is even condensation in the switch cabinet, because the position of the condensation sensor installed inside the cabinet does not reach the level of condensation, or the condensation The dew sensor has been eroded by dust and gas in the air for a long time, which affects the sensitivity of the sensor. The dew controller cannot start the heater in time, resulting in the failure of the dew control function and the normal operation of the equipment. to threaten.

具体实施方式detailed description
下面结合附图所示的实施例对本发明作进一步描述。The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
实施例一：如附图1所示，由于环网柜1底部与窨井相连，窨井内的潮湿水汽容易经缝隙进入环网柜1内部，从而在气温剧烈变化时容易造成凝露，故而本环网柜防凝露系统，采用半导体露点除湿器2和通风除湿装置两部分相结合的方案。半导体露点除湿器2设置于放置环网柜1的空间内，在该空间内，可以均布多个半导体露点除湿器2，各个半导体露点除湿器2可以与设置于控制箱3中的同一控制系统相连接，从而实现统一控制。Embodiment 1: As shown in Figure 1, since the bottom of the ring network cabinet 1 is connected to the inspection well, the moist water vapor in the inspection shaft can easily enter the interior of the ring network cabinet 1 through the gap, so that it is easy to cause condensation when the temperature changes sharply. The anti-condensation system of the network cabinet adopts the scheme of combining the semiconductor dew point dehumidifier 2 and the ventilation and dehumidification device. The semiconductor dew point dehumidifier 2 is set in the space where the ring network cabinet 1 is placed. In this space, a plurality of semiconductor dew point dehumidifiers 2 can be evenly distributed, and each semiconductor dew point dehumidifier 2 can be connected with the same control system set in the control box 3. connected for unified control.
通风除湿装置包括在环网柜1的封闭的底部与设置电缆12的电缆窨井7之间形成的风道4、设置于风道4中的风扇5、控制风扇5运转的控制器以及检测风道4内的湿度并与控制器相信号连接的湿度测量传感器。具体的，环网柜1的密封的底部设置有槽钢托架6将其架空，从而在其与电缆窨井7之间有一定距离而形成风道4。风道4具有相对的进风口10和出风口11，进风口10设置有进风百叶8，出风口11设置有出风百叶9，且进风口10内和出风口11内分别设置有一台风扇5。The ventilation and dehumidification device includes an air duct 4 formed between the closed bottom of the ring network cabinet 1 and the cable inspection shaft 7 where the cable 12 is arranged, a fan 5 arranged in the air duct 4, a controller for controlling the operation of the fan 5, and a detection air duct Humidity in 4 and the humidity measurement sensor connected with the controller phase signal. Specifically, the sealed bottom of the ring network cabinet 1 is provided with a channel steel bracket 6 to make it overhead, so that there is a certain distance between it and the cable inspection shaft 7 to form an air duct 4 . The air duct 4 has a relative air inlet 10 and an air outlet 11, the air inlet 10 is provided with an air inlet louver 8, the air outlet 11 is provided with an air outlet louver 9, and the air inlet 10 and the air outlet 11 are respectively provided with a fan 5 .
上述半导体露点除湿器2的控制系统与通风除湿装置的控制器可以整合为同一控制装置并放置于控制箱3内。The above-mentioned control system of the semiconductor dew point dehumidifier 2 and the controller of the ventilation and dehumidification device can be integrated into the same control device and placed in the control box 3 .
上述环网柜防凝露系统，在风道4内设置的湿度测量传感器检测到风道4内湿度较大（如湿度高于50%）时开启风扇5进行抽风；当湿度较低（如湿度低于40%）时，停止抽风，从而防止窨井内潮湿气体上串到环网柜1内，保证潮湿水汽不会进入环网柜1内部。在设置环网柜1的空间内设置半导体露点除湿器2进行除湿，当环网柜1空间内湿度较大（如湿度高于50%）时，开启除湿，当湿度较低（如湿度低于40%）时，停止除湿，以保证环网柜1内部湿度稳定在40%至50%之间。In the anti-condensation system of the above-mentioned ring network cabinet, the humidity measurement sensor installed in the air duct 4 detects that the humidity in the air duct 4 is relatively high (such as humidity higher than 50%), and the fan 5 is turned on for ventilation; when the humidity is low (such as humidity When it is lower than 40%), stop the ventilation, so as to prevent the humid gas in the inspection shaft from being strung up into the ring main unit 1, and ensure that the damp water vapor will not enter the ring main unit 1. A semiconductor dew point dehumidifier 2 is installed in the space where the ring network cabinet 1 is installed for dehumidification. When the humidity in the space of the ring network cabinet 1 is high (such as the humidity is higher than 50%), the dehumidification is turned on. When the humidity is low (such as the humidity is lower than 40%), stop the dehumidification to ensure that the internal humidity of the ring main unit 1 is stable between 40% and 50%.
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention shall fall within the protection scope of the present invention.
