Description
技术领域 technical field
本实用新型涉及电力系统设备的防潮、除湿装置，尤其是涉及一种用于变电站户外端子箱除湿加热装置。 The utility model relates to a moisture-proof and dehumidifying device for power system equipment, in particular to a dehumidifying and heating device for an outdoor terminal box of a substation.

变电站中户外端子箱是一个不可或缺的设备，是变压器、断路器等室外电气设备和保护装置、测量控制、通信装置联系的中接点。一般就地安装在设备旁。在空气潮湿时，尤其是在雨季，潮气和湿气容易从端子箱底部的用于走线的通孔进入端子箱，造成端子箱内潮湿凝露积水。如果端子箱内长期存在凝露积水现象，会大大缩短端子箱的使用寿命，端子箱内潮湿容易导致箱内端子排连接片或者螺丝腐蚀生锈，使其二次端子接触不良，使电流回路因局部电阻增大而产生发热现象，严重者甚至会导致回路开路，还易导致直流二次回路对地绝缘电阻下降，引起直流保险熔断，保护拒动或误动，甚至损坏设备，严重威胁电网的安全运行。 The outdoor terminal box in the substation is an indispensable equipment, and it is the contact point for the connection between outdoor electrical equipment such as transformers and circuit breakers, protection devices, measurement control and communication devices. It is generally installed next to the equipment on site. When the air is humid, especially in the rainy season, moisture and humidity can easily enter the terminal box from the through holes at the bottom of the terminal box for wiring, causing moisture condensation and water accumulation in the terminal box. If there is condensation and water accumulation in the terminal box for a long time, the service life of the terminal box will be greatly shortened. The humidity in the terminal box will easily lead to the corrosion and rust of the terminal strips or screws in the box, making the secondary terminals in poor contact and causing the current loop Heating occurs due to the increase of local resistance. In severe cases, it may even lead to an open circuit, and it may also easily lead to a decrease in the insulation resistance of the DC secondary circuit to the ground, causing the DC fuse to blow, the protection refuses to operate or malfunctions, and even damages the equipment, seriously threatening the power grid. safe operation.
目前，端子箱防潮措施主要是在端子箱底部加装加热器和在端子箱上侧开通风口，但是经过长时间运行发现底部加热器对端子箱内空气加热不均匀，造成端子箱底部温度过高，易使得箱内的电缆发脆，加速电缆的老化。同时由于温度过高容易使得端子箱底部与电缆沟相连部分的的封堵材料变质，破坏端子箱与电缆沟的密封，为电缆沟的潮气入侵留下隐患。 At present, the moisture-proof measures for the terminal box are mainly to install a heater at the bottom of the terminal box and open a vent on the upper side of the terminal box. However, after a long period of operation, it was found that the heater at the bottom heated the air in the terminal box unevenly, resulting in excessive temperature at the bottom of the terminal box. , it is easy to make the cables in the box brittle and accelerate the aging of the cables. At the same time, because the temperature is too high, the sealing material at the bottom of the terminal box and the cable trench will deteriorate, destroying the seal between the terminal box and the cable trench, leaving hidden dangers for the moisture intrusion in the cable trench.
