Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for controlling electric shock protection according to an embodiment of the present invention, where the method is applicable to a case where electric shock protection control is performed on an electric power device, and the method may be executed by an electric shock protection control apparatus, and the apparatus may be implemented in a software and/or hardware manner. The device can be configured in the control equipment for electric shock protection. As shown in fig. 1, the method includes:
step S110, acquiring monitoring data of an emergency protection device in the power equipment; the emergency protection device is used for monitoring the working environment and the electric leakage condition of the power equipment.
The power device may be a device having a power generation function and/or a power supply function. For example, the electrical device may be a switchgear, a power distribution facility in a power distribution room, a generator, a contactor, or the like. Because outdoor cubical switchboard and distribution facility are located the lower places of relief such as roadside in the city, receive the rainwater invasion easily, in case take place the condition that outdoor cubical switchboard and distribution facility water invaded, will have serious electric shock risk, influence resident's life power consumption. And because the faults of the power grid are frequent when the flood disaster happens, which area can not be expected to have dangerous situations, the emergency personnel can not take the rain day and night to rush to repair, and therefore, the electric power operation and maintenance rush-repair personnel also have serious risks of wading and electric shock.
The emergency protection device can be a device arranged in the power equipment and used for monitoring the working environment and the electric leakage condition of the power equipment and sending monitoring data to the control device for electric shock protection provided by the embodiment of the invention. For example, the emergency protection device may include a monitoring module, a communication module, an early warning module, and the like. The monitoring module can be used for monitoring the working environment and the electric leakage condition of the power equipment. The communication module can be used for sending monitoring data to the electric shock protection control device provided by the embodiment of the invention, receiving a control instruction sent by the electric shock protection control device and sending the control instruction to the early warning module. The communication module can also send the monitoring data to the user terminal and receive the control instruction sent by the user terminal. The early warning module can be used for receiving the control command sent by the communication module and sending out an alarm signal and/or executing power-off operation according to the control command.
Illustratively, the working environment and the leakage condition of the electrical equipment are monitored through a monitoring module in the emergency protection device, and the monitoring data sent by the monitoring module is received through a communication module in the emergency protection device, so that the monitoring data of the communication module in the emergency protection device is obtained.
Fig. 2 is a schematic structural diagram of a shock protection control system according to an embodiment of the present invention. As shown in fig. 2, an emergency protection device may be provided in each power equipment. The control device for electric shock protection provided by the embodiment of the invention can be in communication connection with a plurality of emergency protection devices and is used for carrying out the control method for electric shock protection provided by the embodiment of the invention on the emergency protection devices in each power equipment.
And step S120, analyzing the set safety interval to which the monitoring data belongs, and determining the safety level of the power equipment according to the analysis result.
The set safety interval may be a plurality of preset data ranges, and is used to determine the safety level corresponding to the monitoring data. For example, the set safety interval may be set by a user according to the actual situation of the location of the power equipment.
The safety level of the electrical equipment may be a safety risk level set by a user according to a set safety interval, and the safety level is used for grading the safety risk of the electrical equipment. For example, the safety level of the power equipment may include a low level, an early warning level, a sub-emergency level, an emergency level, and the like. Wherein a low level indicates that the power device is in a safe state. The early warning level indicates that the power equipment is in a light leakage state and an alarm needs to be given out to remind nearby people. The sub-emergency level represents a moderate leakage condition, a need to sound an alarm to alert nearby personnel, and a need for user control of whether an emergency power outage is required to avoid electrocution of nearby personnel. The power equipment being in an emergency level indicates that the power equipment is in a heavily leaky state, an alarm needs to be issued to alert nearby personnel, and an emergency power off is needed to prevent nearby personnel from getting an electric shock. The safety level of the power equipment may be further divided by a first level, a second level, and a third level. Wherein the first level is a highest level indicating that the power equipment needs to be immediately emergently powered off. The level of the second level is lower than the first level, which indicates that the power equipment does not need to be powered off but needs to send out an alarm signal. The third level is lower than the second level, and indicates that the power equipment is in a safe state without power failure and without sending an alarm signal. The division of the safety level of the power equipment may also be implemented in other feasible manners, which is not specifically limited by the present invention.
The safety levels of the power equipment correspond to the set safety intervals one by one. For example, the set safety interval may include a first interval, a second interval, a third interval, and a fourth interval. The lowest value of the second interval is greater than the maximum value of the first interval, the lowest value of the third interval is greater than the maximum value of the second interval, and the lowest value of the fourth interval is greater than the maximum value of the third interval. The first section corresponds to a low level, the second section corresponds to an early warning level, the third section corresponds to a secondary emergency level, and the fourth section corresponds to an emergency level.
If the monitoring data comprises one type of data, analyzing a set safety interval to which the monitoring data belongs, and determining the safety level of the power equipment according to the set safety interval. And when the monitored data is analyzed to belong to the first interval, determining that the safety level of the power equipment is a low level. And when the monitored data is analyzed to belong to the second interval, determining that the safety level of the power equipment is the early warning level. And when the monitored data belong to the third interval, determining that the safety level of the power equipment is a secondary emergency level. And when the monitored data belong to the fourth interval, determining that the safety level of the power equipment is an emergency level.
If the monitoring data comprises at least two types of data, respectively analyzing set safety intervals to which the at least two types of data belong, respectively determining corresponding safety levels according to the analyzed set safety intervals, and taking the highest level of all the safety levels as the safety level of the power equipment. For example, the monitoring data may include water level data and step voltage data, wherein the water level data belongs to a set second water level interval, and the corresponding safety level is determined to be an early warning level according to the second water level interval. And the step voltage data belongs to a set third voltage interval, and the corresponding safety level is determined to be a secondary emergency level according to the third voltage interval. The safety level of the power equipment is determined to be the sub-emergency level since the sub-emergency level is higher than the pre-warning level.
And S130, if the safety level belongs to a preset early warning level, sending an early warning control instruction to the emergency protection device so as to control the emergency protection device to send out an alarm signal and/or execute power-off operation according to the early warning control instruction.
The preset early warning level can be a level interval determined according to the electric shock risk of each safety level. For example, if the safety levels of the power equipment include a low level, an early warning level, a sub-emergency level and an emergency level, wherein the early warning level, the sub-emergency level and the emergency level may cause electric shock hazard to people near the power equipment, the early warning level, the sub-emergency level and the emergency level may be set as preset early warning levels by a user. If the safety level of the power equipment determined in step S120 belongs to one of the preset early warning levels, it indicates that the power equipment has an electric shock risk, and an electric shock protection control needs to be performed on an emergency protection device in the power equipment.
The early warning control command can be used for controlling the emergency protection device to send out an alarm signal and/or execute power-off operation. For example, if the safety level is one of the early warning level, the sub-emergency level and the emergency level, an early warning control command is sent to the emergency protection device to control the emergency protection device to send out an alarm signal according to the early warning control command. And if the safety level is the emergency level, sending an early warning control instruction to the emergency protection device so as to control the emergency protection device to execute power-off operation according to the early warning control instruction.
According to the embodiment of the invention, the monitoring data of the emergency protection device in the power equipment is acquired, the set safety interval to which the monitoring data belong is analyzed, the safety level of the power equipment is determined according to the analysis result, and if the safety level belongs to the preset early warning level, the early warning control instruction is sent to the emergency protection device so as to control the emergency protection device to send out the warning signal and/or execute the power-off operation according to the early warning control instruction. According to the embodiment of the invention, the safety level of the power equipment is judged by analyzing the acquired monitoring data, and the emergency protection device in the power equipment is remotely controlled to send out an alarm signal and/or execute power-off operation when the power equipment has a leakage risk, so that the risk of hurting people due to large-area leakage in a severe environment is reduced, and the safety of the power equipment is improved.

For example, the Data transmission Unit may be a Data Transfer Unit (DTU) including a Central Processing Unit (CPU) control sub-Unit, a wireless communication sub-Unit, and a power supply sub-Unit. The data transmission unit can send the water level data and/or the step voltage data to the control device for electric shock protection.
The sound and light alarm unit can be an alarm capable of simultaneously emitting sound and light alarm signals and is used for reminding people nearby the power equipment that the power equipment has a leakage risk.
The emergency execution unit may be a unit supporting an emergency power-off function for emergency power-off when the safety level of the power equipment reaches a certain level.
Optionally, the monitoring data comprises water level data and/or step voltage data. As shown in fig. 4, the emergency protection device may monitor water level data near the power equipment through the water intrusion early warning monitoring unit, and send the water level data to the control device for electric shock protection provided in the embodiment of the present invention through the data transmission unit, and the control device for electric shock protection may obtain the water level data sent by the emergency protection device through the data acquisition module 3. The emergency protection device can also detect the step voltage data near the power equipment through the grounding detection unit and send the step voltage data to the control device for electric shock protection provided by the embodiment of the invention through the data transmission unit, and the control device for electric shock protection can obtain the step voltage data sent by the emergency protection device through the data acquisition module 3.
For example, as shown in fig. 4, the control device for electric shock protection according to the embodiment of the present invention may include a data acquisition module, a data analysis module, and an early warning control module. The early warning control module can comprise an alarm control unit and an emergency control unit. The control device for electric shock protection can acquire monitoring data of the emergency protection device in the power equipment through the data acquisition module.

For example, as shown in fig. 4, the control device for electric shock protection may analyze a set safety interval to which the monitoring data belongs by the data analysis module 3, and determine the safety level of the power equipment according to the analysis result.
Optionally, analyzing the set safety interval to which the monitoring data belongs, and determining the safety level of the power equipment according to the analysis result may include:
comparing the water level data with a first water level threshold and a second water level threshold;

Specifically, if the monitoring data includes one of water level data or step voltage data, whether the water level data exceeds a set normal value or not is judged by comparing the water level data with a water level threshold, or whether the step voltage data exceeds a set normal value or not is judged by comparing the step voltage data with a voltage threshold, so that whether electric leakage of the power equipment can occur to cause electric shock hazard or not is judged. And meanwhile, the power equipment is judged to be in the dangerous state grade according to the difference between the water level data or the step voltage data and the set normal value. If the monitoring data comprise water level data and step voltage data, the safety level corresponding to the water level data and the safety level corresponding to the step voltage data are respectively determined, the safety level of the power equipment is determined by comprehensively analyzing the two safety levels, and the electric shock risk of the power equipment can be accurately evaluated.
