Description

Technical Field

[0001] The invention relates to the technical field of power system measurement, and more particularly to a hanging current sensitive device for measuring the current on the contact surface of a vertically overlapped conductor. Background Art

[0002] With the continuous upgrading and transformation of the power system, new technologies such as new energy power generation and smart grid are being used more and more widely. For example, the access to the power grid of solar photovoltaic power generation, wind power generation, tidal power generation, etc., which are widely promoted and used at home and abroad, has brought much greater disturbances to the power grid than the disturbances of traditional thermal power generation. With the development of ultra-high voltage transmission and transformation technology, the requirements for the accuracy, insulation, anti-electromagnetic interference ability, weight, volume, etc. of current transformers are getting higher and higher. Compared with traditional current transformers, fiber optic current transformers have the advantages of good insulation performance, strong anti-electromagnetic interference ability, high measurement accuracy, small size, light weight, large measurement dynamic range, and wide bandwidth.

[0003] At present, in the steel, metallurgy, machinery, and chemical industries, there are many vertically overlapped conductors used to transmit large currents. When using traditional fiber-optic current transformers to measure the current transmitted by this conductor, if it is impossible to insert it from one end of the conductor, it is necessary to temporarily cut off the circuit and connect the current sensitive device in series to the power grid line. With the widespread use of electricity in life, even a short-term cutoff of the power supply will bring huge economic losses.

[0004] Therefore, when measuring the current at the contact surface of two vertically overlapped conductors, how to ensure that the measurement can be performed without power failure, thereby reducing the economic losses caused by the measurement, is a problem that technical personnel in this field urgently need to solve.

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

[0073] The embodiment of the present invention discloses a hanging current sensing device for measuring the current on the contact surface of a vertically bonded conductor, which is used for measuring the vertically bonded conductor, wherein the vertically bonded conductor includes a horizontal conductor and a vertical conductor; specifically: the structure of the hanging current sensing device is based on the limitation of the pipeline assembly, and is used for hanging the hanging current sensing device on the horizontal conductor without separating the horizontal conductor and the vertical conductor in the vertically bonded conductor;

[0074] For details, please refer to Figure 1 As shown, the pipeline assembly includes a first upper card area 001, a second upper card area 002, a first lower card area 003 and a second lower card area 004; the first upper card area 001 and the second upper card area 002 are both adapted to the width of the horizontal conductor, and are both used to be clamped on the upper side of the horizontal conductor; the first lower card area 003 and the second lower card area 004 are both used to be clamped on the lower side of the horizontal conductor; the distance d1 between the first upper card area 001 and the second upper card area 002, and the distance d2 between the first lower card area 003 and the second lower card area 004, are both adapted to the width of the vertical conductor, that is, d1=d2.

[0075] See also Figure 2~Figure 10As shown, the above-mentioned first upper clamping area 001 includes a PVC elbow A7 and a first PVC elbow C151; the second upper clamping area 002 includes a PVC elbow B9 and a second PVC elbow C152; the first lower clamping area 003 includes a PVC elbow E19; the second lower clamping area 004 includes a PVC elbow D17; the PVC elbow A7 and the PVC elbow B9 are connected by a glass fiber tube A8; the PVC elbow E19 and the PVC elbow D17 are connected by a glass fiber tube C18; the first PVC elbow C151 and the PVC elbow E19 are connected by a first glass fiber tube B161; the second PVC elbow C152 and the PVC elbow D17 are connected by a second glass fiber tube B162.

[0076] A rotating assembly is provided between the PVC elbow B9 and the second PVC elbow C152; based on the rotating assembly, the PVC elbow A7, the glass fiber tube A8 and the PVC elbow B9 can be rotated as a whole, so that the hanging current sensing device can be hung on the horizontal conductor of the vertical overlapping conductor (for details, see Figure 8 shown);

[0077] The above-mentioned rotating assembly is composed of a front rotating member 10, a limiting pin 11, an upper fixing clip 12, a lower fixing clip 13 and a rear rotating member 14; wherein the front rotating member 10, the limiting pin 11, the upper fixing clip 12, the lower fixing clip 13 and the rear rotating member 14 form an axial rotating mechanism; specifically: the upper fixing clip 12 and the lower fixing clip 13 are semicircular ring structures, the rear rotating member 14 is located between the upper fixing clip 12 and the lower fixing clip 13, and is rotatably connected with the upper fixing clip 12 and the lower fixing clip 13; the upper fixing clip 12 and the lower fixing clip 13 are connected by screws; the front rotating member 10 is used to rotate relative to the upper fixing clip 12 and the lower fixing clip 13. The fixing clamp 12, the lower fixing clamp 13 and the rear rotating member 14 rotate axially; the limiting pin 11 is installed on the front rotating member 10, and the rotation angle of the front rotating member 10 is limited by the limiting groove on the upper fixing clamp 12; it is ensured that when the PVC elbow A7, the glass fiber tube A8 and the PVC elbow B9 are rotated as a whole, the rotation angle can be kept within the preset range to prevent the hanging current sensitive device from being damaged during use, and at the same time, it can also prevent the PVC elbow A7, the glass fiber tube A8 and the PVC elbow B9 as a whole from damaging the vertical lap conductor when rotating at will.

[0078] In a specific implementation, the front rotating member 10, the upper fixing clamp 12, the lower fixing clamp 13 and the rear rotating member 14 are made of glass fiber reinforced plastics, which have good mechanical properties and are insulating and high temperature resistant.

[0079] The optical components in the above-mentioned hanging current sensitive device are composed of a reflector 1, a sensitive optical fiber 2, a wave plate 3 and a transmission optical fiber 4; wherein the sensitive optical fiber 2 is arranged inside the pipeline component and the rotating component; one end of the sensitive optical fiber 2 is in the PVC curved tube A7, which is used for coating a high-reflection film to form a reflector 1; the other end of the sensitive optical fiber 2 is in the first PVC curved tube C151, which is used for 0° axial welding with one end of the wave plate 3; the other end of the wave plate 3 is 45° axial welding with the transmission optical fiber 4; when current flows through, the magnetic field generated will cause the polarization of light passing through the sensitive optical fiber to rotate; one end of the sensitive optical fiber is processed into a reflector, so that the light incident on the sensitive optical fiber can be reflected back to the original path, thereby forming a closed-loop path, increasing the optical path, and enhancing the sensitivity to changes in the magnetic field; due to the presence of the wave plate and the special welding method, this polarization change will be converted into a change in light intensity or other measurable parameters; finally, these changes can be converted into electrical signals through the transmission optical fiber, and then the corresponding current size can be calculated.

[0080] The above-mentioned reflector 1 is fixed based on a reflector mounting assembly; specifically, the reflector mounting assembly consists of a reflector mounting block 5 and a reflector cover 6; the reflector mounting block 5 and the reflector cover 6 form a box body for accommodating the reflector 1; the reflector 1 is fixed to a specified position of the reflector mounting block 5 by gluing; the reflector cover 6 is connected to the reflector mounting block 5 by screws.

[0081] In a specific implementation, the reflector mounting block 5 and the reflector cover plate 6 are made of glass fiber reinforced plastics, which has good mechanical properties and is insulating and high temperature resistant.

[0082] The wave plate 3 is fixed based on the wave plate mounting assembly; specifically, the wave plate mounting assembly includes a wave plate mounting block 20, a wave plate cover 21, a lock 22 and a spring 24; the wave plate mounting block 20 and the wave plate cover 21 form a box body for storing the wave plate 3; the wave plate 3 is fixed to the specified position of the wave plate mounting block 20 by gluing; the wave plate cover 21 is connected to the wave plate mounting block 20 by screws; two locks 22 with springs 24 are provided on the wave plate mounting block 20; the lock 22 is matched and connected with the reflector mounting block 5; see Figure 8 As shown, when the lock 22 is pressed, the reflector mounting block 5 can be disconnected from the wave plate mounting block 20, and the hanging current sensitive device can be installed on the vertical overlapping conductor. After the installation is completed, the reflector mounting block 5 and the wave plate mounting block 20 are closed, and the lock 22 can lock the reflector mounting block 5 and the wave plate mounting block 20 to ensure the stability of the hanging current sensitive device on the vertical overlapping conductor; after the test is completed, the reflector mounting block 5 and the wave plate mounting block 20 are separated, and the hanging current sensitive device can be taken out.

[0083] In a specific implementation, the wave plate mounting block 20 and the wave plate cover plate 21 are made of glass fiber reinforced plastics, which has good mechanical properties and is insulating and high temperature resistant.

[0084] The wave plate mounting assembly further comprises a Glenn head 23 ; the Glenn head 23 is used to fix the transmission optical fiber 4 .

[0085] The plurality of PVC bent pipes and the plurality of glass fiber pipes in the above-mentioned pipeline assembly, as well as the reflector mounting block 5, the front rotating member 10, the rear rotating member 14, and the wave plate mounting block 20 are all connected by gluing.

[0086] In the specific implementation, PVC elbows, as the name implies, are made of PVC material, which has good insulation and mature elbow processing technology. The molding process of glass fiber tubes is to impregnate glass fiber filaments with resin and solidify them in a high-speed polymerization device that integrates light, electricity and heat, and then pultrude them into a shape. Glass fiber tubes are characterized by light weight and hardness, non-conductive, high mechanical strength, anti-aging, high temperature resistance, and corrosion resistance.

[0087] Reference Figures 11 to 13 , which is a schematic diagram of the structure of a hanging current sensing device for measuring the current on the contact surface of a vertically overlapped conductor according to the present invention, installed on a vertically overlapped conductor; specifically, when the hanging current sensing device 100 is in use, the reflector mounting assembly and the wave plate mounting assembly are combined together and fixed by a lock buckle 22. The hanging current sensing device 100 is hung on the horizontal conductor 200, and its front and rear position and up and down position relative to the horizontal conductor 200 are limited by its own structural characteristics; its left and right position relative to the horizontal conductor 200 is limited by the vertical conductor 300; therefore, during use, the hanging current sensing device 100 is relatively fixed in position, and its hanging posture is relatively stable, and does not need to be fixedly installed.

[0088] Next, the specific steps of installing the hanging current sensing device provided by the embodiment of the present invention on the vertically bonded conductor are described in detail. Figures 14 to 19 As shown:

[0089] Step 1: First, the hanging current sensing device 100 is fully opened, and then placed horizontally below the horizontal conductor 200 and on one side of the vertical conductor 300 (at Fig.14 The opening direction faces the vertical conductor 300;

[0090] Step 2: Move the hanging current sensing device 100 horizontally toward the opening direction (at Fig.15 3. The vertical conductor 300 is inserted thereinto;

[0091] Step 3, rotating the hanging current sensing device 100 around the vertical conductor 300 (at Fig.16 (in the middle, it rotates counterclockwise), still in a horizontal position, with the opening facing outwards;

[0092] Step 4: Rotate the hanging current sensing device 100 around the horizontal conductor 200 to a vertical position with the opening located above the horizontal conductor 200. Fig.17 ;

[0093] Step 5: Close the hanging current sensing device 100, and finally suspend the structure above the horizontal conductor 200. Fig.18 .

[0094] In a specific implementation, there are two types of hanging current sensing devices 100: Fig.18 For example, the commonly used reflector mounting assembly and the wave plate mounting assembly are combined at the upper left. In special cases, when the hanging current sensing device 100 cannot be inserted from the right side of the vertical conductor 300 and needs to be inserted from the left side of the vertical conductor 300, the hanging current sensing device 100 is adjusted to a left-right mirror type to Fig.19 For example, the reflector mounting assembly and the wave plate mounting assembly are combined in the upper right corner.

[0095] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0096] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
