Description

Technical Field

[0001] The invention relates to a hanging wire type electromagnetic resonance deicing device, which is specifically suitable for deicing overhead high-voltage cables, overhead ground wires or OPGW optical cables. Background Art

[0002] Transmission line ice disasters can cause power outages, disconnections, and other accidents. To solve this problem, existing solutions mainly use thermal deicing methods and mechanical deicing methods.

[0003] Chinese patent application No. 202110968894.3 discloses a transmission line drone thermal deicing device. The core goal of this technology is to generate heat energy through a heating device to melt snow or ice, thereby maintaining the normal operation of the line.

[0004] Although this method shows high efficiency in removing snow or ice, it also has the following disadvantages: 1) This technology requires a lot of energy to provide enough heat to melt snow or ice. This will lead to a significant increase in energy costs, increase the economic burden of line operations, and may have a negative impact on the environment. 2) A sensitive monitoring system is required to promptly detect snow or ice on the line surface. If the monitoring system is not sensitive enough or fails, the deicing operation will not be started in time, which may cause line damage or service interruption. 3) Thermal stress may be generated on the surface of the heated cable during thermal deicing, and long-term use may have a negative impact on the structure and performance of the cable. 4) The application of thermal deicing technology is particularly difficult in mountainous and hilly areas. Due to the complex terrain and inconvenient transportation in these areas, it is very difficult to carry and install deicing equipment; it is difficult to effectively cover and process all ice points in complex terrain, which greatly reduces the deicing efficiency.

[0005] Mechanical deicing uses mechanical devices, such as rotating brushes, scrapers or vibrating devices, to remove snow or ice from the cable surface by physical friction. This method is simple and direct and is suitable for different types of cables and environmental conditions. However, it also has the following disadvantages: 1) Mechanical deicing needs to be operated when weather conditions permit. Under extremely severe weather conditions, such as strong winds and low temperatures, the mechanical device may not operate properly, which may affect the deicing effect and may even pose a threat to the safety of the operator. 2) Mechanical deicing may cause a certain degree of damage to the cable surface. Especially when using hard devices such as scrapers, excessive friction may cause wear or scratches on the cable surface, thereby reducing the service life of the cable and increasing maintenance costs. 3) Mechanical deicing requires frequent maintenance and cleaning. Since the mechanical device may be hindered by snow or ice during operation, it needs to be cleaned and maintained regularly to ensure the normal operation of the device. This increases the complexity and cost of deicing operations, especially in large-scale line applications, which is extremely costly. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] As shown in the figure, the hanging wire type electromagnetic resonance deicing device of the present invention comprises:

[0059] Piston rod 4;

[0060] A cable clamp 1 is provided at the upper end of the piston rod, and the cable clamp is used to fix the piston rod on the cable;

[0061] A secondary coil 16 is provided at the lower end of the piston rod;

[0062] Conductive slides 18 are provided on opposite sides of the secondary coil;

[0063] The two lead-out ends of the secondary coil are electrically connected to the conductive sliding piece;

[0064] The driving device comprises a housing 13 and a piston cylinder 3 arranged on the housing;

[0065] The piston cylinder 3 is sleeved on the outside of the piston rod 4; a cylinder cover is arranged on the upper end of the piston cylinder, and a sliding hole matching the piston rod is arranged on the cylinder cover; the piston rod is slidably arranged in the sliding hole; a return spring 2 is sleeved on the piston rod in the piston cylinder; the lower end of the return spring 2 is arranged on the lower section of the piston rod 4;

[0066] The annular primary coil 14 is arranged in the upper layer of the shell, corresponding to the secondary coil at the lower end of the piston rod; the secondary coil at the lower end of the piston rod extends into the primary coil; a conductive slide rail is arranged in the primary coil corresponding to the conductive slide outside the secondary coil, and the conductive slide rail is electrically connected with the conductive slide rail;

[0067] The annular primary coil and the secondary coil are connected in series via a conductive slide and a conductive slide rail; after power is turned on, the magnetic properties generated by the annular primary coil and the secondary coil are opposite;

[0068] The power supply and control device are arranged at the lower layer of the shell and are used to discharge the power supply to the annular primary coil and the secondary coil according to a predetermined program or receiving a control signal.

[0069] Working process: Before the arrival of winter, the cable clamp on the piston rod is used to fix the device on the cable; when de-icing is required, a control signal is sent to the control device, and after receiving the de-icing signal, the control device causes the power supply to discharge to the annular primary coil and the secondary coil; the series-connected annular primary coil and the secondary coil will generate a magnetic field at the same time, because the magnetic properties generated by the annular primary coil and the secondary coil are opposite; so the shell where the annular primary coil is located and the piston rod where the secondary coil is located will move relative to each other (generally 20-40mm) to generate vibration, and the piston rod will transfer the vibration to the cable using the cable clamp to make the cable vibrate, and the vibration is used to achieve the purpose of de-icing.

[0070] As shown in the figure, the power supply of the present invention includes: a battery, a boost unit, a pulse energy storage unit, and an energy discharge unit.

[0071] The battery can be selected according to the needs, such as a rechargeable energy storage battery, etc.; the working voltage of the battery can be designed according to the needs, such as 24V, 48V, etc.

[0072] A boost unit, used to boost the battery voltage to a predetermined voltage, generally above 1000 volts;

[0073] Pulse energy storage unit: a high-voltage pulse capacitor used to store and release large amounts of electrical energy.

[0074] The energy dissipation unit uses a controlled switch; the controlled switch in the present invention can be selected from various solid-state switches as needed; for example, semiconductor devices (such as thyristors, bipolar transistors, insulated gate bipolar transistors (IGBTs), field effect transistors (MOSFETs), etc.) are used to control the opening and closing of the current. These semiconductor devices can adjust their conduction state through control signals, thereby realizing circuit control.

[0075] The control device mainly includes a host, a remote controller, a voltage collector and a current collector. The remote controller can be various wireless communication devices, such as a remote control device, a 3G, 4G, 5G communication device, etc.; it mainly completes the reception of instructions issued by the remote control, and the host can be various single-chip microcomputers, PLCs, etc., which are used to decompose the instructions and control the controlled switches, etc. The voltage collector is composed of two series resistors R3 and R4, which are connected in parallel at both ends of the capacitor. The voltage at both ends of R4 can be measured in real time to know the voltage at both ends of the capacitor; the current collector is a coil set in the discharge circuit, and the size of the magnetic field generated by the discharge circuit during the discharge process is used to confirm its discharge current.

[0076] Specifically, one end of the annular primary coil is connected to the high-voltage return bus 1, one end of the secondary coil is connected to the sliding electrical contact connection device 1 and is slidably connected to the high-voltage bus 1, and the other end of the secondary coil is connected to the sliding electrical contact connection device 2 and is slidably connected to the high-voltage return bus 2. During operation, the primary coil and the secondary coil are connected in series, and the current passes through the primary coil input end, the primary coil output end, the high-voltage bus 1, the sliding electrical contact connection device 1, the secondary coil input end, the secondary coil output end, the sliding electrical contact connection device 2 and the high-voltage bus 2 in sequence. Under the impetus of the electromagnetic force, the secondary coil is pushed forward.

[0077] The mechanical vibration device includes a cable fixing clamp, a vibration spring, a piston cylinder, and a piston rod. One end of the piston rod is connected to the secondary coil of the propulsion device, and the other end is connected to the cable fixing clamp, and cooperates with the piston cylinder through the vibration spring. The piston cylinder is fixed to the primary coil of the propulsion device. Under the impact of the propulsion device, in conjunction with the device's own gravity, the piston rod of the mechanical vibration device is repeatedly moved, which produces periodic impacts on the overhead cables and achieves the effect of deicing.

[0078] The piston cylinder is composed of a plurality of columns, which may be two, four or more columns, and this shape has the effect of reducing weight.

[0079] The shell mainly adopts a high-strength metal frame, and an epoxy resin plate is used inside the frame to achieve the fixation of high-voltage equipment and the insulation between each other, and the settings inside the fixed frame can be designed according to needs; for example: it is divided into four layers from bottom to top; the first layer (the lowest layer) mainly includes a charging power supply; the second layer includes a measurement and control host, an energy discharge unit, and a vacuum switch; the third layer includes a pulse energy storage unit and a current collector; the fourth layer (upper layer) includes a solid-state switch, a primary coil, and a voltage collector.

[0080] The fixing frame is hollowed out, which has the effects of strong stability and light weight.

[0081] The method for using the hanging wire type electromagnetic resonance deicing device comprises the following steps in sequence:

[0082] Step 1: Turn on the measurement and control system switch of the equipment to put the equipment into working state.

[0083] Step 2: Fix the cable clamp to the cable to ensure that the ice-breaking device is perpendicular to the cable.

[0084] Step 3: The staff uses the remote control to send a working signal to the equipment. The hanging wire electromagnetic resonance deicing device works, and the working steps include the following parts:

[0085] 1. Charge the pulse energy storage unit. After receiving the signal, the host controls the vacuum switch to close and sends a working instruction to the charging power supply to complete the charging of the pulse energy storage unit. In this working state, the host of the measurement and control system collects the voltage of the pulse energy storage unit in real time through the voltage collector. When the voltage reaches the charging target voltage value, the charging power supply is stopped and the high-voltage vacuum switch is disconnected to complete the charging process of the pulse energy storage unit.

[0086] 2. The pulse energy storage unit discharges the propulsion system. In this step, the measurement and control system sends a trigger signal to the solid-state switch, and the pulse energy storage unit completes the discharge of the propulsion system. Driven by the electromagnetic force, the secondary coil accelerates, thereby driving the piston rod to move upward rapidly, thereby driving the entire device to move upward, thereby driving the cable to move upward to achieve the de-icing effect; in this process, the current collector will collect the discharge current and transmit it to the remote control for data recording and analysis.

[0087] 3. After the secondary coil completes the acceleration movement, under the action of the spring and its own gravity, it will vibrate repeatedly in a decaying manner to achieve a further de-icing effect.

[0088] 4. After the de-icing is completed (repeated vibration), the high-voltage switch is closed to complete the discharge process of the pulse energy storage unit, ensuring that the pulse energy storage unit is always in a discharged state when not in operation, thereby ensuring the safety of staff and equipment.

[0089] Step 4: After deicing is completed, multiple deicing cycles can be performed at regular intervals, or the equipment can be moved to another location to complete the next deicing.

[0090] Charging and discharging process:

[0091] 1. Charging circuit: vacuum switch K1 is closed, vacuum switch 2 is disconnected, charging power supply BT1 charges pulse energy storage unit C1, and vacuum switch K1 is disconnected when charging is completed.

[0092] 2. Discharge circuit: vacuum switch K1 is disconnected, vacuum switch 2 is disconnected, and pulse energy storage unit C1 discharges primary coil L1 and secondary coil L2 through solid-state switch K3.

[0093] 3. Energy dissipation circuit: vacuum switch K1 is disconnected, vacuum switch 2 is closed, and pulse energy storage unit C1 discharges electricity to the energy dissipation device.

[0094] 4. During the charging process, the voltage collector detects the voltage of the pulse energy storage unit through the voltage collection point A1

[0095] 5. During the discharge process, the discharge circuit current is collected through the current collection point.
