Description
技术领域technical field
本发明涉及电力安全防护技术领域，具体而言，涉及一种可穿戴跨步电压报警装置。The invention relates to the technical field of electric power safety protection, in particular to a wearable step voltage alarm device.
背景技术Background technique
目前，《国家电网公司电力安全工作规程》(变电部分)5.2.4条规定：高压设备发生接地时，室内人员应距离故障点4米以外，室外工作人员应距离故障点8米以外。之所以这样规定，是因为当电气设备发生碰壳故障、导线断裂落地或线路绝缘击穿而导致单相接地故障时，电流便经接地体或导线落地点呈半球形向大地流散。类似将一块石头投入水中，会出现很多圆圈，离圆心越近的地方，电位越高，离圆心越远的地方，电位越低，同一圆圈的电位则是相同的。如果有人走进这些形成不同电位的圆圈，两只脚承受的电位差就形成了跨步电压。当人接触到跨步电压时，电流将通过人体，虽然电流没有通过人体的重要器官，仅沿着下半身流过，但当跨步电压较高时，就会发生双脚抽筋，跌倒在地上的情况，由于头脚之间的距离大，故作用于人身体上的电压增高，电流相应增大，并且有可能使电流通过人体的重要器官，引起人身触电死亡事故。At present, Article 5.2.4 of the "State Grid Corporation Electric Power Safety Work Regulations" (substation part) stipulates that when high-voltage equipment is grounded, indoor personnel should be 4 meters away from the fault point, and outdoor workers should be 8 meters away from the fault point. The reason for this regulation is that when a single-phase grounding fault occurs due to a shell failure of electrical equipment, a wire breaks to the ground, or a line insulation breakdown, the current will flow to the earth in a hemispherical shape through the grounding body or the grounding point of the wire. Similar to throwing a stone into water, many circles will appear. The closer to the center of the circle, the higher the potential, and the farther away from the center, the lower the potential. The potential of the same circle is the same. If someone walks into these circles forming different potentials, the difference in potential experienced by the two feet creates the step voltage. When a person is exposed to the step voltage, the current will pass through the human body. Although the current does not pass through the vital organs of the human body and only flows along the lower body, when the step voltage is high, the feet will cramp and fall to the ground. Due to the large distance between the head and feet, the voltage acting on the human body increases, and the current increases accordingly, and the current may pass through the vital organs of the human body, causing personal electric shock death accidents.
输配电线路和变电设备的定期巡视、恶劣天气前后的特巡和故障巡视是电力设备运维人员的日常工作。变、配电运维人员和线路运维人员带电巡视故障高压设备或线路时，需要运维人员具备较强的专业素质，特别是在输配电线路发生接地故障时，由于无法提前预知故障设备或线路接地故障点，运维人员误入故障设备或线路接地点8米以内，导致跨步电压伤害的事故时有发生，对运维人员造成人身伤害。Regular inspections of transmission and distribution lines and substation equipment, special inspections before and after severe weather and fault inspections are the daily work of power equipment operation and maintenance personnel. Substation and distribution operation and maintenance personnel and line operation and maintenance personnel need to have strong professional quality when patrolling faulty high-voltage equipment or lines with electricity, especially when a ground fault occurs on the transmission and distribution line, because the faulty equipment cannot be predicted in advance Or the line grounding fault point, the operation and maintenance personnel strayed into the faulty equipment or line grounding point within 8 meters, resulting in step voltage damage accidents occurred from time to time, causing personal injury to the operation and maintenance personnel.
常规的避免跨步电压触电事故的方法是穿绝缘靴或双脚并紧跳跃前行，穿绝缘靴可以避免发生触电事故，但是不易及时发现接地故障点；双脚并紧跳跃前行的方法也不利于运维人员长时间巡视，因此，如何使运维人员及时发现故障设备或线路接地点，避免跨步电压导致人身触电伤害是迫在眉睫的。The conventional method for avoiding step voltage electric shock accidents is to wear insulated boots or jump forward with both feet tightly. Wearing insulating boots can avoid electric shock accidents, but it is difficult to find the ground fault point in time; It is not conducive to the operation and maintenance personnel to patrol for a long time. Therefore, how to make the operation and maintenance personnel find the faulty equipment or the grounding point of the line in time to avoid personal electric shock injury caused by step voltage is imminent.

目前，变、配电运维人员和线路运维人员带电巡视故障高压设备或线路时，由于无法提前预知故障设备或线路接地故障点，运维人员误入故障设备或线路接地点8米以内，导致跨步电压伤害的事故时有发生，对运维人员造成人身伤害，基于此，本发明实施例提供的一种可穿戴跨步电压报警装置，可以使运维人员及时发现故障设备或线路接地点，避免跨步电压导致人身触电伤害。At present, when substation and distribution operation and maintenance personnel and line operation and maintenance personnel patrol faulty high-voltage equipment or lines with electricity, because they cannot predict the grounding fault point of the faulty equipment or line in advance, the operation and maintenance personnel stray into the grounding point of the faulty equipment or line within 8 meters. Accidents that lead to step voltage damage occur from time to time, causing personal injury to operation and maintenance personnel. Based on this, a wearable step voltage alarm device provided by the embodiment of the present invention can enable operation and maintenance personnel to find faulty equipment or line connections in time. location, to avoid personal electric shock caused by step voltage.
实施例一：Embodiment one:
如图1所示，本发明实施例提供了一种可穿戴跨步电压报警装置，包括电压传感器1、计算器2、控制器3和报警器4。该可穿戴跨步电压报警装置穿戴在变、配电运维人员和线路运维人员双脚上，其中，电压传感器1用于感知当前脚步的电压，将获得的电压发送到计算器2，计算器2接收电压传感器1发来的电压，计算出跨步电压值，控制器3用于在跨步电压值超过阈值时，向报警器4发出预警信号，报警器4接收到预警信号后，发出警报，提醒巡视中的运维人员有跨步电压，需要注意安全，且接地故障点就在附近。As shown in FIG. 1 , an embodiment of the present invention provides a wearable step voltage alarm device, including a voltage sensor 1 , a calculator 2 , a controller 3 and an alarm 4 . The wearable step voltage alarm device is worn on the feet of substation and distribution operation and maintenance personnel and line operation and maintenance personnel, wherein the voltage sensor 1 is used to sense the voltage of the current step, and the obtained voltage is sent to the calculator 2 for calculation The controller 2 receives the voltage sent by the voltage sensor 1, and calculates the step voltage value, and the controller 3 is used to send an early warning signal to the alarm 4 when the step voltage value exceeds the threshold, and the alarm 4 sends out an alarm after receiving the early warning signal. The alarm reminds the operation and maintenance personnel on patrol that there is a step voltage, and they need to pay attention to safety, and the ground fault point is nearby.
具体的，报警器4包括声音模块和光模块。声音模块用于发出语音提示，包括跨步电压值超过阈值时的报警语音、处于故障地点附近的可穿戴跨步电压报警装置编号和位置信息等内容，光模块用于光电转换，将电信号转换成光信号。报警器4接收控制器3发送的预警信号，启动声音模块和光模块，发出报警语音和光信号。Specifically, the alarm 4 includes a sound module and a light module. The sound module is used to issue voice prompts, including the alarm voice when the step voltage value exceeds the threshold, the number and location information of the wearable step voltage alarm device near the fault location, etc. The optical module is used for photoelectric conversion to convert electrical signals into an optical signal. The alarm 4 receives the early warning signal sent by the controller 3, activates the sound module and the light module, and sends out the alarm voice and light signal.
进一步的是，本实施例中，还包括互感器5，用于降低经过人体的跨步电压。当报警器4发出警报的同时，互感器5用于降低经过人体的跨步电压，隔绝跨步高电压，将高电压变成低电压，可以在第一时间内最大限度的降低人身伤害，保障运维人员的人身安全。Furthermore, in this embodiment, a transformer 5 is also included for reducing the step voltage passing through the human body. When the alarm 4 gives an alarm, the transformer 5 is used to reduce the step voltage passing through the human body, isolate the high step voltage, and turn the high voltage into a low voltage, which can minimize personal injury in the first time and guarantee Personal safety of operation and maintenance personnel.
本实施例中，具体的，如图2所示，控制器3包括输入模块31和比较模块32。输入模块31用于输入有可能对人体造成伤害的跨步电压的阈值和当前可穿戴跨步电压报警装置的编号。《国家电网公司电力安全工作规程》规定，当高压设备发生接地时，室外工作人员的安全距离是8米以外，理论上，跨步电压不允许超过40V。为了保护变、配电运维人员和线路运维人员的人身安全，实际应用中，可以根据运维人员的身体情况以及巡视场地的情况，将阈值设置为大于10V且小于40V的某一数值，使运维人员既可以发现故障设备或线路接地点，又不会造成人身损害。当多个运维人员带电巡视故障高压设备或线路时，每人穿戴的跨步电压报警装置都设置有一个编号，总部监控和整体控制各个可穿戴跨步电压报警装置时不易混乱，各个运维人员之间的联系也可以更加方便。比较模块32用于将计算器2计算的当前脚步的跨步电压值与阈值进行比较，当前跨步电压值小于阈值时，比较模块32不作响应，继续工作，当前跨步电压值大于阈值时，比较模块32响应，控制器3向报警器4发出预警信号。In this embodiment, specifically, as shown in FIG. 2 , the controller 3 includes an input module 31 and a comparison module 32 . The input module 31 is used for inputting the threshold value of the step voltage that may cause harm to the human body and the serial number of the current wearable step voltage alarm device. The "State Grid Corporation Electric Power Safety Work Regulations" stipulates that when the high-voltage equipment is grounded, the safety distance of outdoor workers is 8 meters. In theory, the step voltage is not allowed to exceed 40V. In order to protect the personal safety of substation and distribution operation and maintenance personnel and line operation and maintenance personnel, in practical applications, the threshold can be set to a certain value greater than 10V and less than 40V according to the physical condition of the operation and maintenance personnel and the situation of the inspection site. So that the operation and maintenance personnel can find the faulty equipment or the grounding point of the line without causing personal injury. When multiple operation and maintenance personnel patrol the faulty high-voltage equipment or lines with electricity, the step voltage alarm devices worn by each person are equipped with a number, so that it is not easy to be confused when the headquarters monitors and controls each wearable step voltage alarm device as a whole. Connections between personnel can also be made easier. Comparison module 32 is used to compare the step voltage value of the current step calculated by calculator 2 with the threshold value, when the current step voltage value is less than the threshold value, the comparison module 32 does not respond, and continues to work, when the current step voltage value is greater than the threshold value, The comparison module 32 responds, and the controller 3 sends an early warning signal to the alarm 4 .
优选的是，如图2所示，控制器还包括计时器33，用于计算警报持续的时间。Preferably, as shown in FIG. 2 , the controller further includes a timer 33 for counting the duration of the alarm.
本实施例中，控制器还包括呼救模块34，呼救模块34在警报持续的时间超过预设值时，向总部发出呼救信号，使总部能够及时发现异常情况。报警持续的时间过长，说明运维人员长时间处于跨步电压过高的环境中，极有可能造成身体损害，总部人员发现此异常情况后，可以及时联系该运维人员或者现场的其他运维人员，确认该运维人员的身体状况，及时参与救援，将损害降至最低。预设值可以依据巡视环境的实际情况设定。In this embodiment, the controller also includes a distress call module 34, which sends a distress call signal to the headquarters when the duration of the alarm exceeds a preset value, so that the headquarters can find abnormal situations in time. If the alarm lasts too long, it means that the operation and maintenance personnel have been in the environment with too high step voltage for a long time, which is very likely to cause physical damage. After the headquarters personnel find this abnormal situation, they can contact the operation and maintenance personnel or other operators on site in time. Maintenance personnel, confirm the physical condition of the operation and maintenance personnel, participate in the rescue in time, and minimize the damage. The preset value can be set according to the actual situation of the inspection environment.
此外，控制器3还包括定位模块35，定位模块35用于定位呼救信号发出的准确位置和故障地点的准确位置。当呼救模块34发出呼救信号后，总部可以根据定位模块35显示的定位信息，确认现场运维人员的准确位置。当巡视中的运维人员发现故障设备或线路接地点时，定位模块35可以准确地定位该位置。In addition, the controller 3 also includes a positioning module 35, which is used for locating the exact location of the distress signal and the location of the fault. After the distress call module 34 sends out a distress call signal, the headquarters can confirm the exact location of the on-site operation and maintenance personnel according to the positioning information displayed by the positioning module 35 . When the patrolling operation and maintenance personnel find a faulty device or a line grounding point, the location module 35 can accurately locate the location.
进一步的是，如图1所示，本发明实施例提供的可穿戴跨步电压报警装置中，还包括通信模块6，用于将装置编号和位置信息发送至其他可穿戴跨步电压报警装置。并且，通信模块6还用于接收其他可穿戴跨步电压报警装置发送的装置编号和位置信息。该通信模块用于运维人员发现故障地点后，发出信号通知其他运维人员。Further, as shown in FIG. 1 , the wearable step voltage alarm device provided by the embodiment of the present invention also includes a communication module 6 for sending the device number and location information to other wearable step voltage alarm devices. Moreover, the communication module 6 is also used to receive device numbers and location information sent by other wearable step voltage alarm devices.
