背景技术 Background technique

本实用新型中所述的材料均为市场上能买到的公知的材料，但是本实用新型并不限于上述材料。 The materials described in the utility model are known materials available on the market, but the utility model is not limited to the above materials.
本实用新型的工作原理是： The working principle of the utility model is:
首先，在横担、降压变压器T、绝缘子表面敷设电伴热带3。若电伴热带3的长度不够时，可通过电伴热带中间接线盒12进行延伸。并在电伴热带3的末端安装电伴热带终端接线盒13，使电伴热带3的端口与外界可靠隔绝。其次，将电伴热带电源接线盒4和温度传感器5与降压变压器T连接，降压变压器T为两者提供电源。融冰雪装置的电伴热带3工作与否是由温度传感器5检测的信号决定，自动开关的动作是通过融冰雪装置开关控制电路来控制。 Firstly, electric heating cable 3 is laid on the surface of cross arm, step-down transformer T and insulator. If the length of the electric heating cable 3 is not enough, it can be extended through the intermediate junction box 12 of the electric heating cable. And install the electric heating cable terminal junction box 13 at the end of the electric heating cable 3, so that the port of the electric heating cable 3 is reliably isolated from the outside world. Secondly, connect the electric heating cable power junction box 4 and the temperature sensor 5 with the step-down transformer T, and the step-down transformer T provides power for both. Whether the electric heating cable 3 of the ice and snow melting device works or not is determined by the signal detected by the temperature sensor 5, and the action of the automatic switch is controlled by the switch control circuit of the ice and snow melting device.
如图4所示，起始时，继电器K2的常闭触点均为闭合状态。当温度传感器5检测到环境温度低于-3℃时，融冰雪装置开关控制电路中的开关K2不动作，即处于闭合状态。此时，电伴热带3通电而工作，从而使得塔架、横担、绝缘子及降压变压器T表面的冰雪被融化。当温度传感器5检测到环境温度高于-3℃时，融冰雪装置开关控制电路中的开关K2动作，即处于断开状态。此时，融冰雪装置的电伴热带3因断电而停止工作，杆塔9上也可以装上电伴热带3用来融化其上的冰雪，输送电缆8架设在杆塔9之间的绝缘子7上。 As shown in Figure 4, at the beginning, the normally closed contacts of the relay K2 are all closed. When the temperature sensor 5 detects that the ambient temperature is lower than -3°C, the switch K2 in the switch control circuit of the ice and snow melting device does not act, that is, it is in a closed state. At this time, the electric heating cable 3 is energized to work, so that the ice and snow on the surface of the tower, the cross arm, the insulator and the step-down transformer T are melted. When the temperature sensor 5 detects that the ambient temperature is higher than -3°C, the switch K2 in the switch control circuit of the ice and snow melting device acts, that is, it is in an off state. At this time, the electric heating cable 3 of the ice and snow melting device stops working due to a power outage, and the electric heating cable 3 can also be installed on the pole tower 9 to melt the ice and snow thereon, and the transmission cable 8 is erected on the insulator 7 between the pole towers 9 .
所述融冰雪装置开关控制电路的工作原理如下：如图4所示，220V电压通过降压变压器T降压、VD1-VD4整流、C滤波和IC1稳压后得到12V的直流电压为融冰雪装置开关控制电路供电，LED1为电源工作指示灯，由电子开关集成电路IC2和VD5构成温度检测电路（即温度传感器5及其构成的电路），当温度低于RP的设定值（如-3℃）时，VD5的阻值较大，IC2的5脚电位低于触发电压，IC2的2、3脚之间的电子开关截止，继电器K2（也就是自动开关10）都不动作，融冰雪装置通过其常闭触点通电而工作，电伴热带3工作除去输电系统的横担、降压变压器和绝缘子表面的冰雪。当温度达到设定值（如-3℃）时，随着VD5阻值的不断减小，IC2的5脚电位不断升高，超过其触发电压，从而使IC2的2、3脚之间的电子开关导通，继电器K2吸合，其常闭触点断开，从而使融冰雪装置停止工作，电伴热带3不工作，同时LED2亮。当温度降低到设定值以下时，融冰雪装置又工作，如此周而复始，就可以自动除去输电系统的横担、降压变压器和绝缘子表面的冰雪。 The operating principle of the switch control circuit of the ice and snow melting device is as follows: as shown in Figure 4, the 220V voltage is stepped down by the step-down transformer T, rectified by VD1-VD4, C is filtered and stabilized by IC1 to obtain a DC voltage of 12V as the ice and snow melting device The switch control circuit supplies power, LED1 is the power supply indicator light, and the temperature detection circuit is composed of the electronic switch integrated circuit IC2 and VD5 (that is, the temperature sensor 5 and its circuit). When the temperature is lower than the set value of RP (such as -3°C ), the resistance of VD5 is large, the potential of pin 5 of IC2 is lower than the trigger voltage, the electronic switch between pin 2 and pin 3 of IC2 is cut off, the relay K2 (that is, the automatic switch 10) does not act, and the ice and snow melting device passes through Its normally closed contact works when it is energized, and the electric heating cable 3 works to remove ice and snow on the surface of the cross arm, step-down transformer and insulator of the power transmission system. When the temperature reaches the set value (such as -3°C), as the resistance of VD5 continues to decrease, the potential of pin 5 of IC2 continues to rise, exceeding its trigger voltage, so that the electrons between pins 2 and 3 of IC2 The switch is turned on, the relay K2 is pulled in, and its normally closed contact is disconnected, so that the ice and snow melting device stops working, the electric heating cable 3 does not work, and the LED2 is on at the same time. When the temperature drops below the set value, the ice and snow melting device will work again, and the ice and snow on the surface of the crossarm, step-down transformer and insulator of the power transmission system will be automatically removed.
本实用新型的有益效果是：此装置通过温度传感器来监测环境的温度，再利用融冰雪装置开关控制电路来控制电伴热带的工作与否，进而融化横担、绝缘子及降压变压器等表面的冰雪，从而保证了山区等特殊地理和气候环境下的输电系统上的冰雪能被及时、有效地清除，进而避免由于大雪而造成的灾害，减少了经济损失，该装置具有结构简单、运行可靠、成本低、便于控制等优点。 The beneficial effects of the utility model are: the device monitors the temperature of the environment through a temperature sensor, and then uses the switch control circuit of the ice and snow melting device to control whether the electric heating belt is working or not, and then melts the surface of the cross arm, insulator and step-down transformer. Ice and snow, thus ensuring that the ice and snow on the power transmission system in mountainous areas and other special geographical and climatic environments can be removed in a timely and effective manner, thereby avoiding disasters caused by heavy snow and reducing economic losses. The device has simple structure, reliable operation, Low cost, easy to control and other advantages.
