Description

Technical Field

[0001] The present invention relates to a monitoring device for low-voltage overhead power lines, and in particular to an integrated outdoor low-voltage overhead power line monitoring terminal comprising a current sensor, a voltage power-taking device, an electronic device, a housing structure, and an installation mechanism. Background Art

[0002] Low-voltage power lines are connected to thousands of households and bear the important responsibility of direct power supply. Low-voltage power lines include low-voltage cable power lines and low-voltage overhead power lines. Low-voltage cable lines are located in sheltered places such as cable trenches, electrical wells, and wire troughs, are not easily damaged by external forces, are less affected by environmental factors, and are convenient for construction. There are already many low-voltage electrical devices connected to low-voltage cable lines. Relying on existing low-voltage electrical devices or installing low-cost indoor low-voltage monitoring devices, it is relatively easy to carry out line monitoring work.

[0003] Low-voltage overhead lines are located outdoors, are easily affected by the external environment, and are difficult to construct. There are fewer outdoor low-voltage electrical devices connected to low-voltage overhead lines. At the same time, outdoor low-voltage electrical devices need to have waterproof capabilities, so the cost is relatively high. Low-voltage overhead lines have few faults, long lines, and large coverage areas. Deploying real-time online monitoring devices has a low cost-effectiveness. The above factors result in a lack of existing low-voltage overhead line monitoring devices and make it difficult to carry out monitoring work. However, for low-voltage distribution network operation and maintenance work such as low-voltage distribution network capacity planning, three-phase imbalance monitoring and treatment, etc., it is necessary to obtain effective monitoring data of low-voltage overhead lines to guide the above work. Starting from the actual situation of low-voltage distribution network operation and maintenance work, there is a need for an outdoor low-voltage overhead power line monitoring device that can effectively obtain three-phase current and voltage information for a long time, has the structural characteristics of convenient installation and waterproof capabilities, and has a relatively low comprehensive use cost.

[0004] In Chinese Patent CN105119378A, a low-voltage power distribution line online monitoring system is disclosed, which includes a low-voltage monitoring device. However, this device only has the functions of power-off monitoring and power-off information reporting.

[0005] In Chinese Patent CN205246805U, a low-voltage power distribution line online monitoring system is disclosed, which includes an intelligent line fault acquisition terminal. This terminal is simultaneously connected to a voltage sensor, a current sensor, a data acquisition processor, and a GPRS wireless communication module. However, this device only has the functions of low-voltage line fault detection and location.

[0006] Chinese Patent CN204758706U discloses a low-voltage distribution network load imbalance monitoring device, which can collect three-phase current, three-phase voltage and zero-sequence current, and has functions of information processing, storage and wireless transmission, and can realize the monitoring of the feeder loop. However, this device only includes a signal conditioning circuit, does not have current and voltage sensors integrated with the device, and does not involve whether the device is applicable to low-voltage overhead lines and whether it has corresponding structural features.

[0007] Chinese Patent CN106291036A discloses an integrated low-voltage monitoring device, which has an integrated current transformer module composed of a voltage transformer, a current transformer, an electric energy metering module and a CPU processor. The device also includes a display panel, and a circuit breaker is connected to the front end of the device. Similarly, it does not involve whether the device is applicable to low-voltage overhead lines and whether it has corresponding structural features.

[0008] Chinese Patent CN210129011U discloses a low-voltage distribution network fault monitoring device. The acquisition module of this device includes 5 current transformers, which respectively collect the currents of phase A, phase B, phase C, phase N and ground wire of the low-voltage distribution network. The device also has a display module at the same time. However, this device does not collect three-phase voltage signals, and does not involve whether the device is applicable to low-voltage overhead lines and whether it has corresponding structural features.

[0009] Chinese Patent CN208571532U discloses a card-mounted installation structure for a low-voltage power line integrated monitoring terminal. This structure respectively includes current transformers for three phases and the neutral line adopting a card-mounted installation structure. The current transformers adopt a waterproof structure housing in a specific embodiment, as well as voltage piercing clamps for three phases and the neutral line. This structure can be used for overhead power lines. However, this structure only involves the installation structure of the transformer of the monitoring terminal, and does not involve the overall structure of the monitoring terminal and its structural features.

[0010] Chinese Patent CN209070025U discloses a low-voltage power distribution monitoring device and a low-voltage power distribution service system. This monitoring device includes a main monitoring device and a secondary monitoring device, and can monitor the transient magnetic induction variables of the line and the load. However, it does not involve the specific monitoring of three-phase current and voltage of low-voltage lines, nor does it involve whether the device is applicable to low-voltage overhead lines and whether it has corresponding structural features.

[0011] Based on the above existing patents, it can be found that there are existing low-voltage power line monitoring equipment and devices, lacking outdoor low-voltage overhead power line monitoring equipment required for the actual operation and maintenance work of low-voltage distribution networks, unable to effectively obtain the three-phase current and voltage information of outdoor low-voltage overhead lines for a long time, and not having structural features of convenient outdoor installation and waterproof ability. Summary of the Invention

[0012] In order to effectively provide the three-phase current and voltage information of long-time outdoor low-voltage overhead power lines for the actual operation and maintenance work of low-voltage distribution networks, the present invention provides an integrated outdoor low-voltage overhead power line monitoring terminal, which can effectively obtain the three-phase current and voltage information of long-time outdoor low-voltage overhead lines, has the advantages of convenient outdoor installation and waterproof ability, and relatively low comprehensive use cost.

[0013] The technical solution adopted by the present invention is an integrated outdoor low-voltage overhead power line monitoring terminal, including an electronic device, a non-metallic waterproof housing, two spiral clamping mechanisms, two first structural members, two second structural members, three waterproof openable and closable current sensors with puncture power taking and their connecting cables, a waterproof openable and closable wire clamp with puncture power taking and its connecting cable, four cable waterproof fixing joints, and three waterproof live indication modules. It is characterized in that: the two spiral clamping mechanisms are respectively connected to the two first structural members, the two first structural members are respectively connected to the two second structural members, and the two second structural members are respectively connected to both ends of the housing of the non-metallic waterproof housing along the direction of the overhead power line. The three waterproof openable and closable current sensors with puncture power taking and their connecting cables and a waterproof openable and closable wire clamp with puncture power taking and its connecting cable respectively pass through the four cable waterproof fixing joints and enter the interior of the non-metallic waterproof housing to be connected to the electronic device inside the non-metallic waterproof housing. The three waterproof openable and closable current sensors with puncture power taking and a waterproof openable and closable wire clamp with puncture power taking are placed at both ends of the two second structural members when not installed. The three waterproof live indication modules are located on the non-metallic waterproof housing and are connected to the puncture power taking parts of the three waterproof openable and closable current sensors with puncture power taking and a waterproof openable and closable wire clamp with puncture power taking.

[0014] The above-mentioned electronic device includes a power supply circuit module, a signal conditioning circuit module, a signal acquisition and processing module, a data storage module, a wireless communication module, and an antenna. The power supply circuit module provides power for the signal conditioning circuit module, the signal acquisition and processing module, the data storage module, and the wireless communication module. The signal acquisition and processing module acquires the output analog signal of the signal conditioning circuit module, converts it into a digital signal, performs arithmetic processing to obtain three-phase current and voltage information, stores it in the data storage module according to the acquisition time, and transmits the three-phase current and voltage information through the wireless communication module. The antenna is connected to the wireless communication module.

[0015] The above-mentioned spiral clamping mechanism is provided with a spiral mechanism and an opening clamping mechanism. When the spiral mechanism rotates along a rotation direction, the opening clamping mechanism can be closed. When the spiral mechanism rotates in the opposite direction of the above rotation direction, the opening clamping mechanism can be opened.

[0016] The two spiral clamping mechanisms are respectively located on both sides of the non-metallic waterproof housing along the direction of the overhead power line. The opening direction of the opening clamping mechanism of the spiral clamping mechanism on one side of the non-metallic waterproof housing is in the opposite direction to the opening direction of the opening clamping mechanism of the spiral clamping mechanism on the other side of the non-metallic waterproof housing. The integrated outdoor low-voltage overhead power line monitoring terminal is installed by clamping the neutral line N through the two spiral clamping mechanisms.

[0017] The two first structural members are respectively connected to the two spiral clamping mechanisms and the two second structural members.

[0018] The two second structural members are respectively connected to the two first structural members and the two ends of the non-metallic waterproof housing.

[0019] The two second structural members respectively have hook mechanisms at their two ends. The three waterproof openable and closable current sensors with puncture power taking and the one waterproof openable and closable wire clamp with puncture power taking are located on the hook mechanisms when not installed on the overhead power line.

[0020] When the three waterproof openable and closable current sensors with puncture power taking and their connecting cables are installed on the overhead power line, the parts of the waterproof openable and closable current sensors with puncture power taking are respectively located on the A, B, and C phase lines, and the puncture power taking parts are connected to the conductor parts of the three-phase lines. When the one waterproof openable and closable wire clamp with puncture power taking and its connecting cable are installed on the overhead power line, the waterproof openable and closable wire clamp with puncture power taking is located on the neutral line N, and the puncture power taking part is connected to the conductor part of the neutral line N. The connecting cables of the waterproof openable and closable current sensors with puncture power taking and the connecting cable of the waterproof openable and closable wire clamp with puncture power taking respectively have sheath colors the same as the phase indication colors of the connected A, B, and C phase lines and the neutral line N, and respectively pass through the four cable waterproof fixing joints and enter the interior of the non-metallic waterproof housing.

[0021] The connection cable outlets of the above three waterproof opening and closing current sensors with puncture power extraction include current sensor outlets and puncture power extraction outlets. The connection cable outlet of the above one waterproof opening and closing wire clamp with puncture power extraction only has a puncture power extraction outlet. The current sensor outlet in the connection cable of the waterproof opening and closing current sensor with puncture power extraction is connected to the signal conditioning circuit module in the above electronic device to generate a current signal. The puncture power extraction outlet in the connection cable of the waterproof opening and closing current sensor with puncture power extraction, and the puncture power extraction outlet in the connection cable outlet of the waterproof opening and closing wire clamp with puncture power extraction are connected to the signal conditioning circuit module in the above electronic device to generate a voltage signal and are also connected to the power supply circuit module in the above electronic device to generate power.

[0022] The above three waterproof live indication modules are located on the above non-metallic waterproof housing. The above three waterproof live indication modules include indicator lights and indicator light power supplies. The indicator light power supplies of the above three waterproof live indication modules supply power to the indicator lights of the above three waterproof live indication modules. The indicator light power supply has two input poles, positive and negative. The three positive input poles are respectively connected to the puncture power extraction outlets in the connection cables of the above three waterproof opening and closing current sensors with puncture power extraction. The three negative input poles are all connected to the puncture power extraction outlet in the connection cable outlet of the waterproof opening and closing wire clamp with puncture power extraction. When the puncture power extraction of the above three waterproof opening and closing current sensors with puncture power extraction and the waterproof opening and closing wire clamp with puncture power extraction are connected to the three-phase line and the neutral line N conductor, the indicator light power supply will generate power to light up the indicator lights.

[0023] The beneficial effects of the present invention are: 1. The integrated outdoor low-voltage overhead power line monitoring terminal provided by the present invention adopts an integrated design and can work independently only by itself.

[0026] (3) The monitoring terminal only needs to rely on its own signal conditioning circuit module, signal acquisition processor, data storage device, wireless communication module, antenna and other electronic devices, without the assistance of external equipment, and can work completely independently to realize the collection, processing, storage and transmission of three-phase current and voltage signals, so as to effectively obtain the three-phase current and voltage information of long-term outdoor low-voltage overhead lines.

[0027] 2. The integrated outdoor low-voltage overhead power line monitoring terminal provided by the present invention has good installation convenience.

[0029] (2) During the installation process of the monitoring terminal, the monitoring terminal can be easily installed and removed simply by rotating two spiral clamping mechanisms, without the need to use any external auxiliary installation tools.

[0030] (3) During the installation of the monitoring terminal, three waterproof retractable current sensors with puncture power supply and waterproof retractable wire clamps with puncture power supply are located on the hooks of the monitoring terminal structure and will not move around during the installation process to create risks.

[0031] (4) Before the three waterproof opening and closing current sensors with puncture power supply and the waterproof opening and closing wire clamps with puncture power supply of the monitoring terminal are installed on the three-phase line and the neutral line, the sheath color of the cables connected to the three waterproof opening and closing current sensors with puncture power supply and the waterproof opening and closing wire clamps with puncture power supply can be compared with the phase indication color of the three-phase line and the neutral line to guide the installation and avoid installation errors.

[0032] (5) After the three waterproof open-and-close current sensors with piercing power supply and the waterproof open-and-close wire clamps with piercing power supply of the monitoring terminal are installed on the three-phase line and the neutral line, by checking whether the indicator lights of the three waterproof live indicator modules are on, it can be confirmed whether the piercing power supply part is in good contact with the three-phase line and the neutral line conductor and whether the installation is complete.

[0033] (6) The installation process of the monitoring terminal only requires the installation of three waterproof retractable current sensors with puncture power supply and waterproof retractable wire clamps with puncture power supply. No secondary wiring is required. The installation is completed and the monitoring terminal immediately obtains power supply and current and voltage signals and can work normally.

[0034] 3. The integrated outdoor low-voltage overhead power line monitoring terminal provided by the present invention has waterproof capability and can be used outdoors.

[0035] (1)All electronic devices of the monitoring terminal are located inside a non-metallic waterproof housing, including the antenna used by the wireless communication module.

[0036] (2)The connection cable of the three waterproof opening and closing current sensors with puncture power extraction and the waterproof opening and closing wire clamp of the monitoring terminal enter the interior of the non-metallic waterproof housing through four cable waterproof fixing joints.

[0037] (3)The monitoring terminal uses a waterproof live indicator light.

[0038] 4. The integrated outdoor low-voltage overhead power line monitoring terminal provided by the present invention has a relatively low comprehensive usage cost.

[0039] (1)The installation and disassembly process of the monitoring terminal is very convenient, with a short installation and disassembly time. There is no need to use installation accessories and special installation tools, and the installation cost is relatively low.

[0040] (2)There are no components such as batteries that need to be replaced regularly inside the monitoring terminal. At the same time, it adopts an integrated design and works completely independently, without external wiring and external cooperation, and the maintenance cost is very low.

[0041] (3)After the monitoring terminal completes the monitoring task of a certain outdoor low-voltage overhead power line, it can be moved to another place relatively quickly, which improves the utilization rate of the equipment, increases the cost-effectiveness of the equipment, and reduces the usage cost of the equipment.
