Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering safety auxiliary tools, in particular to a wire clamp anti-freezing device. BACKGROUND

[0002] At present, in order to improve the transmission capacity, transmission economic benefit and transmission reliability of the line, and limit the corona, the split conductor is usually adopted, that is, each phase conductor is composed of several small-diameter sub-conductors, the sub-conductors are arranged at the vertices of a regular polygon at a certain distance and in a symmetrical polygonal shape, and a spacer rod is used to ensure the spacing between the split conductor bundles, prevent the whipping of the conductors, and suppress the wind vibration and sub-span oscillation.

[0003] According to the working characteristics of the spacer rod, it can be divided into two types, namely, a damping type spacer rod and a non-damping type spacer rod. The damping type spacer rod has the following characteristics: at the movable joint of the spacer rod, that is, at the clamp, a rubber damping material is used to consume the vibration energy of the conductor, and a damping effect is generated on the conductor vibration. Therefore, this type of spacer rod is suitable for various regions. However, considering the economy of the transmission line, this type of spacer rod is mainly used for lines in regions where the conductor is prone to vibration. The non-damping spacer rod has poor shock absorption, and can be used for lines in regions where vibration is not prone to occur or as a jumper spacer rod.

[0004] In winter, when the temperature is low and the humidity is high, the damping pad of the clamp is prone to freeze at the contact with the conductor, thereby greatly reducing the effect of the damping pad made of rubber and other damping materials on consuming the vibration energy of the conductor, and when the conductor is vibrated by external factors, it will bear greater tension, and there is a possibility of ice flash, which may cause a short circuit accident, which is not conducive to the safe operation of the transmission line.

[0005] At present, there is a direct current ice melting technology for transmission lines. The direct current ice melting technology mainly applies a direct current voltage to the transmission line and performs a short circuit at the end of the transmission line to heat the conductor and melt the ice on the transmission line. This technology is suitable for large-scale snow and ice weather to clean the ice on the line in time. If this technology is used to prevent the freezing of the clamp in general winter weather, it is a waste of resources, which is troublesome and uneconomical. Therefore, the existing technology lacks a better and more economical solution to prevent the freezing of the clamp. SUMMARY

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] This invention provides an auxiliary heating and anti-freezing device for wire clamps. This invention directly measures data such as ambient temperature and humidity and wire current to monitor whether the conditions for freezing of the clamp have been met under the current conditions. It compares the current conditions with the set heating conditions and determines whether to activate the auxiliary heating device. By increasing the internal temperature of the clamp damping pad, the temperature near the clamp damping pad reaches above the freezing temperature, thereby achieving the goal of preventing wire clamps from freezing in winter.

[0039] Figure 1 This is a first schematic diagram of the wire clamp antifreeze device according to an embodiment of the present invention, as shown below. Figure 1 As shown, in one embodiment of the present invention, the wire clamp antifreeze device of the present invention includes: a measuring device 8 for measuring ambient temperature and humidity, clamp temperature and wire current, a heating circuit 9, a processor 5, and an energy harvesting device 1 for supplying power to the heating circuit and the processor.

[0040] The measuring device is used to send the detected measuring signal to the processor. The processor is used to determine whether a preset heating condition is met based on the measuring signal; if the heating condition is met, it controls the heating circuit to be energized to enable heating; and if the heating condition is not met, it controls the heating circuit to be de-energized.

[0041] This invention utilizes an energy harvesting device to supply power to the control circuit (including a processor) and the heating line. It acquires signals such as temperature, humidity, and current from measuring devices installed in the environment and on the line. These signals are then filtered, amplified, and attenuated by a signal conditioning circuit to become suitable for the processor. The signals are then transmitted to the processor, compared with set conditions, to determine whether to start or stop heating. The corresponding data is stored and uploaded to a server, allowing users to promptly check the heating device's operating status. This prevents conductor clamps from freezing in winter, thereby improving the stability, reliability, and economy of power transmission line operation during winter.

[0042] like Figure 1 and 2 As shown, in one embodiment of the present invention, the processor 5, the first voltage regulator module 2, the second voltage regulator module 4, the energy storage device 3, the first switch, the second switch, and the third switch are all housed in a sealed waterproof housing.

[0043] like Figure 1 As shown, the sealed and waterproof housing is equipped with an energy harvesting device 1, a measuring device 8, and a heating circuit 9. Inside the sealed and waterproof housing are a control circuit board, a first voltage regulator module, and an energy storage device. The connections between the components inside and outside the sealed and waterproof housing must be fully sealed and waterproof. The control circuit board integrates a processor, switching devices, a second voltage regulator module, and signal conditioning devices.

[0044] The processor is used to collect and store the data measured by the measuring device, compare it with the set data, execute corresponding program instructions, and control the working state of the switching device.

[0045] The switching device receives control instructions from the processor to turn the corresponding circuit on and off, thus completing the intended function.

[0046] The power supply regulator (first voltage regulator module and second voltage regulator module) is used to perform voltage conversion, AC to DC and DC to DC. The converted voltage should meet the operating voltage of the corresponding circuit and drive the circuit to work.

[0047] The signal conditioning device is used to process the data measured by the measuring device and transform it into data suitable for the processor to process, so as to avoid the signal directly impacting the processor and causing damage to the processor.

[0048] The energy storage device is used to store electrical energy for backup. When the energy harvesting device is unable to supply power to the circuit, the energy storage device supplies power to the circuit to operate, thus preventing the wire clamps from freezing due to the power failure of the heating device.

[0049] The energy harvesting device can obtain electrical energy from the outside, including direct and indirect acquisition, to supply power to the heating device for operation.

[0050] The measuring device can measure and collect signal data such as ambient temperature and humidity and wire current, which are used as criteria for determining whether the heating device should be started.

[0051] The heating circuit is placed inside the clamp damping pad. The heating wire itself is a resistor; when current and voltage are applied, Joule heat is generated and transferred to the damping pad, raising the internal temperature and preventing freezing. The sealed waterproof housing protects the internal control circuit from operating normally and shields it from electromagnetic interference and various external disturbances.

[0052] The energy harvesting device is connected to the input terminal of the power supply regulator module inside the casing via a waterproof wire. The power supply regulator module outputs a stable DC voltage to power the control circuit board and the energy storage device.

[0053] The measuring device is connected to the circuit board inside the housing via a waterproof wire, and then connected to the processor.

[0054] The circuit board voltage regulator is connected to the internal power supply voltage regulator module, which outputs stable DC power to the processor and other devices that meet the operating voltage requirements.

[0055] The energy storage device is connected to the power supply regulator of the control circuit board to supply power to the control circuit, and is also connected to the heating circuit to supply power to it.

[0056] In an optional embodiment of the present invention, the energy harvesting device includes at least one of: a CT power harvesting device (i.e., a power harvesting CT), a solar power generation device, and a wind power generation device.

[0057] In one specific embodiment of the present invention, the energy harvesting device adopts a CT power harvesting device. The CT power harvesting device can be a switchable CT, which obtains power from any one of the split conductors. Its secondary output is connected to the first voltage regulator input terminal, ensuring a reliable connection and avoiding open circuits. For power supply changes, the first voltage regulator module outputs a stable DC voltage. Multiple CT power harvesting devices can be connected in parallel to increase the output power of the first voltage regulator module. For detailed CT power harvesting principles, please refer to [reference needed]. Figure 3 .

[0058] In one embodiment of the present invention, the measurement signals specifically include: an ambient temperature signal, an ambient humidity signal, a clamp temperature signal, and a conductor current signal. The heating conditions specifically include: an ambient temperature lower than a first preset value, an ambient humidity higher than a second preset value, a clamp temperature lower than a third preset value, and a conductor current lower than a fourth preset value.

[0059] The wire clamp auxiliary heating and anti-freezing scheme of the present invention adopts a combination of feedback-based and direct measurement methods.

[0060] The feedback is based on the measurement device set on the conductor measuring the current of the conductor and comparing it with a threshold (fourth preset value). If the current is large, the conductor itself is a resistor and will generate heat, causing the damping material to heat up and preventing it from freezing. If the current is small, less heat will be generated, which is insufficient to raise the temperature, and heating is required.

[0061] The direct measurement method involves directly measuring the ambient temperature and humidity, comparing them with set conditions (i.e., ambient temperature below a first preset value and ambient humidity above a second preset value), and starting heating when heating conditions are met; and stopping heating when heating conditions are met.

[0062] The direct measurement method involves the processor cyclically monitoring the internal temperature of several line clamp damping pads and cyclically controlling the operation of several heating lines. When the temperature of a certain line clamp damping pad meets the condition of stopping heating (i.e., the clamp temperature is lower than the third preset value), a command is issued to drive the switching device of that line to disconnect, and that heating circuit exits the cyclic heating queue, while the other lines cycle through heating. When all lines have exited the heating queue, a certain period of time must be waited before the heating cycle can be triggered again.

[0063] This invention can prevent the heating circuit from working continuously, which is a form of temperature protection, because every time the switching device is turned on and off, it means a reduction in the life of the switch and an increase in power consumption.

[0064] like Figure 1 and 2 As shown, in one embodiment of the present invention, the wire clamp antifreeze device of the present invention further includes: a first voltage stabilizing module and a second voltage stabilizing module.

[0065] The first voltage regulator module is connected to the energy harvesting device and is used to output DC voltage. The first voltage regulator module is also connected to the heating circuit to supply the output DC voltage to the heating circuit. The second voltage regulator module is connected to the first voltage regulator module and is used to output voltage for the processor to operate.

[0066] like Figure 2 As shown, in one embodiment of the present invention, the output terminals of both the first voltage regulator module and the second voltage regulator module are connected to a forward conducting device. In a specific embodiment of the present invention, the forward conducting device can be a diode.

[0067] The first voltage regulator module can be any AC to DC conversion device. Its output terminal is connected to a forward-conducting device, such as a diode, to prevent the circuit from being reverse-connected and causing irreversible damage to devices with polarity requirements.

[0068] The second voltage regulator module can be any voltage regulator chip. Its input terminal is connected to the output of the first voltage regulator, and its output terminal is connected to the processor power supply terminal via a diode to supply power to it. The diode is also used to prevent reverse connection.

[0069] like Figure 1 and 2 As shown, in one embodiment of the present invention, the wire clamp antifreeze device of the present invention further includes an energy storage device.

[0070] The input terminal of the energy storage device is connected to the output terminal of the first voltage regulator module, and the first voltage regulator module outputs a DC voltage to charge the energy storage device; the output terminal of the energy storage device is connected to the heating circuit and the second voltage regulator module respectively.

[0071] like Figure 2 As shown, in one embodiment of the present invention, the wire clamp antifreeze device of the present invention further includes: a first switch and a second switch; the processor is connected to the first switch and the second switch respectively, and the processor is used to control the opening and closing states of the first switch and the second switch.

[0072] The first switch is located at the output end of the energy storage device and is used to control whether the energy storage device discharges; when the energy harvesting device normally obtains electrical energy, the processor controls the first switch to open; when the energy harvesting device cannot normally obtain electrical energy, the processor controls the first switch to close.

[0073] The second switch is located at the input end of the heating circuit and is used to control the power supply to the heating circuit. When the heating conditions are met, the processor controls the second switch to close; when the heating conditions are not met, the processor controls the second switch to open.

[0074] In this embodiment of the invention, the processor issues an instruction to control the first switch to turn on, thereby charging and storing energy in the energy storage module. After the power to the wire is cut off, the heating circuit and control circuit are provided as backup, thus avoiding freezing of the wire clamp due to the power failure of the wire.

[0075] In this embodiment of the invention, the measuring device 8 specifically includes: a first sensor, a second sensor, and a third sensor.

[0076] The first sensor is a current sensor that monitors the current signal of the conductor. After the signal is conditioned, it is transmitted to the processor. When the conductor current is large, according to the thermal energy formula, the heat energy of the conductor increases, the clamp will not freeze, and the heating device does not need to be started. When the conductor current is very small and approaches zero, the conductor is de-energized, and the current collector (CT) cannot draw power from the conductor to supply the circuit. At this time, the energy storage device supplies power to the heating circuit and the control circuit board to prevent the heating circuit from being de-energized. When the conductor current is within the normal range, the current collector (CT) draws power from the conductor, and the heating circuit works normally.

[0077] The second sensor is a temperature and humidity sensor that measures the ambient temperature and humidity. After second signal conditioning, the temperature and humidity data are transmitted to the processor and compared with the set heating conditions. When the temperature is below a certain degree and the humidity is above a certain percentage, it is determined to start heating.

[0078] The third sensor is a temperature sensor that measures the internal temperature of the clamp damping material. The third switch, which can be an analog switch, turns the small signal of temperature on and off. After the signal is conditioned, it is transmitted to the processor and compared with the set stop heating condition. When the internal temperature is higher than a certain degree, it is determined to stop heating. The processor then issues a command to shut down the heating circuit relay, and the heating circuit exits the cyclic heating queue.

[0079] When the processor determines that heating needs to be activated, it sends a command to trigger the second switch to turn on. This switch can be a magnetic latching relay. The heating circuit then operates, and the third switch turns on. The third sensor works in conjunction with the heating circuit; that is, the sensor and the heating wire are simultaneously placed inside the wire clamp damping pad. (See reference...) Figure 4 and Figure 5 The placement method involves a sensor measuring the temperature of the damping pad of the wire clamp after the heating wire is heated, with several measurement circuits and heating circuits circulating and heating in a loop.

[0080] In one embodiment of the present invention, after all heating circuits are deactivated, a certain period of time needs to be waited before the heating cycle can be restarted.

[0081] In one embodiment of the present invention, the processor can upload data to a server so that users can query the working status of the heating line.

[0082] In one embodiment of the present invention, the measuring device includes: a wire clamp temperature detection sensor (i.e., the aforementioned third sensor). For example...Figure 2 As shown, in one embodiment of the present invention, the wire clamp antifreeze device of the present invention further includes: a third switch for controlling the power supply to and from the wire clamp temperature detection sensor; the processor is connected to the third switch, and the processor is used to control the opening and closing state of the third switch; when the heating circuit is energized, the processor controls the third switch to close; when the heating circuit is not energized, the processor controls the third switch to open.

[0083] See Figure 3 This is a schematic diagram of the power supply for a CT (Cross-Cross Detector). The secondary side of the current transformer is connected to a rectifier bridge. The rectifier bridge outputs DC power, which charges the capacitor via a diode. Once the capacitor has stored energy, it will generate a voltage. This voltage, in conjunction with a Zener diode, will cause the Zener diode to break down and conduct. The current transformer secondary side, the rectifier bridge, and the diode form a circuit, preventing further charging of the capacitor. The voltage signal generated across the capacitor is the voltage produced by the current supply, which powers the subsequent circuits.

[0084] In one embodiment of the present invention, the metal temperature probe of the wire clamp temperature detection sensor and the heating circuit are both disposed inside the wire clamp damping pad.

[0085] See Figure 4 and Figure 5 This diagram illustrates the placement of the heating circuit and the temperature sensor. Holes are drilled in the rubber damping material, and the heating circuit is wound around it. The heating circuit generates heat, which is transferred to the damping material, raising its temperature above freezing point. The metal temperature probe of the temperature sensor is placed inside the rubber to measure the internal temperature of the rubber material. It communicates with the processor and works in conjunction with the heating circuit to perform the heating.

[0086] See Figure 6 A schematic diagram of the placement of the heating circuit and the outer casing is shown. In one embodiment of the invention, the heating circuit is fixed in the middle of the clamp, but the invention is not limited to this and multiple placement schemes can be considered.

[0087] See Figure 7 The heating process diagram is a... Figure 2The specific process is described below. The implementation process of this embodiment is described. Initially, the CT is powered on, the device is started, and the temperature and humidity sensors collect ambient temperature and humidity data. If the temperature is below a certain degree and the humidity is above a certain value, and the conditions are met, the relays of several heating circuits are triggered to cyclically conduct for a certain period of time, and the heating circuit begins to cyclically conduct. If the conditions are not met, the ambient temperature and humidity are collected again. A temperature sensor placed inside the rubber ring collects the temperature inside the rubber ring. If the temperature is above a certain set temperature, and the conditions are met, the processor issues a command to disconnect the relay of that heating circuit and directly switch to the next heating circuit. If the conditions are not met, the measurement is repeated. After all heating is stopped, a certain period of time is waited before the heating cycle is triggered again. This is to prevent continuous heating from wasting energy and affecting the lifespan of the switches.

[0088] As can be seen from the above embodiments, the advantages and effects of the present invention are as follows:

[0089] This invention employs self-powered operation and multiple power extraction methods, including direct power extraction via a CT power extraction device, as well as indirect power extraction methods such as solar panels and wind turbines that convert other forms of energy into electrical energy; it can be any one of these methods or a combination of several, ensuring the continuity and stability of the power supply.

[0090] The present invention includes an energy storage module, which controls the switching devices to be connected to the circuit through the processor, stores electrical energy for backup, and supplies the heating circuit and processor to prevent the device from stopping due to a sudden power outage.

[0091] This invention employs individual temperature measurement and heating for each wire clamp, cyclically, to avoid unlimited heating that would cause switch lifespan loss and power consumption.

[0092] This invention integrates Internet of Things (IoT) technology to feed measurement data back to the user via a server, thereby monitoring the working status of the heating device.

[0093] It should be noted that the specific hardware selection in the embodiments of this disclosure is not limited to one type. The CT power supply device can be designed with specific models and specifications based on the wire diameter and required output power. The type, power, and quantity of heating wires also need to be determined according to the heating object and heating requirements. The housing of the control circuit needs to fully consider its airtightness and waterproofness. It is best to use a spherical plastic housing, but it is not limited to this. Various moisture-resistant and wind-erosion-resistant materials, such as fibers and alloys, can be used. The shape can be designed according to environmental conditions, placement location, and fluid dynamics. The selection of specific circuit components and the layout and wiring of the control circuit board need to consider electromagnetic compatibility (EMC) and have good shielding and anti-interference design to ensure the accurate and stable function of the control circuit. Sensors can be selected from various aspects, such as economy and sensitivity. There are various voltage regulator chips to choose from for the voltage regulator module. Switching modules include ordinary relays, magnetic latching relays, and analog switches. The selection should be based on reducing energy consumption and control stability. The material and model of aviation terminals are not limited to one type. The energy storage module can be a battery or a supercapacitor to supply power to the circuit in a timely manner. There is a switch between the voltage regulator module and the processor to control the switching on and off.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
