technical field

The invention belongs to the technical field of power transmission and transformation equipment operation and disaster prevention, and relates to an auxiliary tool for testing loop resistance of GIS equipment.

Background technique

Due to its simple structure and convenient maintenance, GIS equipment has been widely used in power grids in recent years. Due to the large number of GIS equipment manufacturers and various forms and structures, the grounding side of the GIS grounding switch is not insulated from the shell, and the two circuits on the circuit cannot be used. When the group grounding switch is connected to the circuit to be tested for measurement, it is necessary to inject current from the inlet and outlet bushings for measurement. At this time, it is necessary for the test personnel to climb up to the inlet and outlet bushings on both sides of the GIS equipment, and manually install the test wire clamp for measurement. Due to the compact structure of the GIS equipment, the distance between it and the surrounding area is small, the induction current is too large or the distance is too close to meet the safe distance of the operation, and it is very easy to cause electric shock, high-altitude fall and high-altitude falling objects to injure people when installing and dismantling the test line.

S2. Select the fiber optic cable holder to fix the fiber optic cable during connection. One fiber optic cable holder is installed on the left and right sides of the workbench. Both sides of the holder are flat to fix the workbench. The side with V-shaped groove is used for Fix the fiber optic cable with the opening facing the staff.

The information and communication branch currently maintains 3,000 kilometers of optical cable lines, and needs to weld optical cables hundreds of times a year. Optical cable welding personnel do not have a dedicated optical cable welding operation table when welding optical cables, and use simple folding tables for welding operations. Most of the cable splicing work is located on the mountain, and the folding table is very cumbersome and inconvenient to use. The method is to develop a folding table made of aluminum alloy of 800cm×600cm×500cm, which can be folded in the middle, and the legs of the table can be stretched arbitrarily to adapt to uneven terrain such as mountainous areas. , The slot for fixing the optical cable fusion splicer is designed on the desktop to ensure the stability of the equipment during use. The folding table is designed to place suggested tool slots, so that simple tools can be placed in the folding table during construction. Communication optical cable connection workbench, the bracket is made of high-strength high-manganese steel pipe welded, with the characteristics of lightness, durability, and easy storage and storage. The use size is: length 800mm, width 600mm, height 500mm, which can fully meet any type of splicing box, terminal box, and place any type of welding machine and tools. The holder is made of light-weight wear-resistant aluminum alloy die-casting. Its structure has the characteristics of firm fixed table top, convenient disassembly and installation, and strong random position on the table top. The clamper is suitable for the construction of all general-purpose optical cables with a diameter of 7mm to 28mm. The optical cable splicing workbench is light and suitable for any terrain. The workbench is made of fireproof material, which is not afraid of scalding, bumping and scratching by hard objects. It is suitable for field work scenarios. It can greatly improve work efficiency and shorten the time of cable connection during optical cable connection, which is a good guarantee for field optical cable operations. Welding quality during construction.

2. Implement the method of making the cable manhole cover rainproof and anti-theft, including the following steps:

S1. No holes are set in the cable well cover to prevent rainwater and snow water from pouring into the cable well;

S2. The well ring of the cable manhole cover is made into an upward groove shape, and the edge of the lower surface of the manhole cover is made to protrude downward, embedded in the groove of the well ring; to prevent rainwater from entering the well and to prevent the well cover from shifting and preventing the well cover from being stolen;

S3. The center of the upper surface of the cable manhole cover is made into a circular plane with a diameter of 500mm, which is used to cooperate with a strong magnet to open the manhole cover, and a circular groove with a diameter of 120mm is made on the edge of the circular plane for embedding the information sign number, and also made The 30mm circular groove is used to embed the information chip in the well for scanning and reading information to realize the management of the cable channel in the cable well.

At present, the distribution line and cable equipment in urban areas are increasing day by day, there are many cable wells, and there is no unified information for management. There is a lot of water in the cable wells, which is difficult to clean. There are holes on the manhole covers that cause rainwater to flow into the wells. Iron manhole covers are often damaged and lost. Phenomenon, prone to the danger of people falling into the well. The original manhole cover has the following problems: 1. There are two holes on the manhole cover, which is easy for water to enter. 2. The title of "electric power" is marked on the manhole cover, the time is long and vague, and the information is not clear. 3. Manhole cover locks are often crushed and easy to fail. 4. The alveolar design of the well ring and well cover is simple, easy to be displaced or stolen. The invention develops a novel cable well cover, which has no holes to prevent rainwater and snow water from pouring into the cable well. The well circle is made into an upward groove shape, and the edge of the lower surface of the well cover is designed to protrude downward, embedded in the well circle groove, to prevent rainwater from entering the well and prevent the well cover from shifting and the well cover from being stolen. The center of the upper surface of the well cover is made into a circular plane with a diameter of 500mm, which is used to cooperate with a strong magnet to open the well cover. A circular groove with a diameter of 120mm is made on the edge of the plane for embedding the information sign number, and a circular groove of 30mm is made for embedding in the well. Information chip, read information by scanning. It facilitates the management of the cable channel of the cable well. The cable well cover can effectively prevent rainwater and snow water from entering the cable well, effectively reduce water accumulation inside the cable well, and prevent power outages caused by long-term immersion of power cables in water. The new manhole cover can effectively prevent the manhole cover from shifting to its original position when it is pressed, and the manhole cover cannot be opened without special tools, which plays an anti-theft role and effectively prevents accidents of people and vehicles falling into the well. The new cable manhole cover has a fixed sign installation area, and the embedded sign is wear-resistant, with clear instructions and complete information, which is clearly distinguished from other unit manhole covers. Embedded with a scannable chip, the amount of information is greatly increased, and personnel can clearly grasp the equipment situation and inspection records when passing by. It is helpful for the operation and maintenance of cable lines. The well cover is simple in structure, small in investment, easy to manufacture and easy to install, and is planned to be mass-produced. It will be popularized and applied in the power distribution company of State Grid Benxi Power Supply Company to improve the operation and management level of cable equipment, improve the safety of cable equipment, improve the reliability of power supply, and reduce the number of personnel. Vehicle fall risk.

3. Implement the method of preparing the general-purpose protective cap formwork for transmission towers. Use a steel plate with a thickness of 1mm to weld a fixed formwork with a minimum length of 400mm, and weld a plurality of spliced formworks with a length of 100mm. The number of spliced forms varies with the foundation of the tower. The size of the pile surface is correspondingly increased. The fixed formwork is formed by connecting two mutually perpendicular flat plates, and a fixed plate with a vertical surface is installed on the back of each of the flat plates. The spliced formwork is a flat plate, and some The splicing formwork has a fixed plate with a vertical plate surface; the first fixed plate of the first fixed formwork is connected with the fixed plate of the first spliced formwork by bolts, and the first spliced formwork is spliced with more than one spliced formwork without a fixed plate, and spliced The last splicing template has a fixing plate, which is a second splicing template, and the second splicing template is connected by bolts to the fixing plate of the first flat plate of the second fixed template through its fixing plate, and the second flat plate of the second fixed template The fixing plate and the fixing plate of the third splicing plate are connected by bolts, and the third splicing template is spliced with more than one splicing template without a fixing plate, and the last splicing template to be spliced has a fixing plate, which is the fourth splicing template, The fourth splicing formwork is connected by bolts with the fixing plate of the first plate of the third fixed formwork through its fixing plate, in this way, until a splicing formwork with a fixing plate, it passes through the fixing plate and the second fixed plate of the first fixing formwork. The fixing plate is connected by bolts, so that the fixing formwork and the splicing formwork are surrounded to form a hollow cube-shaped protective cap formwork, and the corners of the protective cap are changed into arcs by means of arc-shaped corner formwork strips.

The above scheme is to install the formwork according to the size of the pile surface of the concrete protective cap after the construction of the power line pole tower, and then pour concrete to form the protective cap and maintain it so that it can reach a certain strength to bear its own weight. Temporary structure, and can A common protective cap formwork for transmission poles and towers is removed and reused.

At present, with the construction of standardized transmission lines, the protection cap of the tower foot is also an important part of it. The protection cap must be strong, free of cracks, and its appearance must not only be standard but also beautiful. The function of the protective cap is: after the construction and assembly of the power line pole tower, in order to protect the nuts of the anchor bolts from being removed and to avoid water accumulation at the tower base, cement mortar must be poured at the tower foot to form a protective layer. Most of the formworks for pouring concrete protection caps are wooden materials, which are used once after making and forming, which wastes materials, cannot be adjusted with the size of the protection caps, and cannot be reused. Secondly, there are few qualified ones after the tower protective cap is formed, and the most important reason is that there is no qualified formwork. Now plywood and wood are used as templates, and nails are used to fix the joints, so that the nails can be easily pulled out after the cement mortar expands, causing deformation of the protective cap. In addition, plywood and wood are disposable, and the size of each protective cap Different, the wooden formwork must be reprocessed every time, which greatly increases the construction cost, and the appearance of the protective cap cannot reach the standard shape. In order to ensure the appearance of the concrete protective cap after construction, save materials and reduce construction costs. The reusable and assembled steel formwork replaces the original disposable wooden formwork made of plywood and wood squares. The invention provides a general-purpose protective cap formwork for transmission poles and towers, which achieves the purpose of easy assembly and repeated use. The above method uses thin steel plates to weld the fixed formwork of the minimum specification for the protective cap, and welds a plurality of splicing formworks in addition. The fixed formwork and the splicing formwork are connected by bolts, which can be increased correspondingly with the size of the pile surface of the tower foundation. It is arc-shaped, which is not only not easy to break but also beautiful, and achieves convenient assembly and repeated use. The specific operation is to use a steel plate with a thickness of 1mm to weld a fixed formwork with a minimum length of 400mm, and to weld multiple 100mm spliced formworks, which can increase with the size of the pile surface of the tower foundation. The fixed formwork and spliced formwork are connected by bolts. In order to make the protective cap durable, the edges and corners of the protective cap are changed into arcs through arc-shaped corner formwork strips, which is not only not easy to break but also beautiful, and achieves the purpose of easy assembly, repeated use, and reduced construction costs. Its beneficial effect is that the size and specification can be adjusted and is suitable for pouring any tower protective cap, and the reused steel material is used instead of wooden material, which greatly reduces the construction cost, avoids the nut from being removed and avoids water accumulation in the tower base, and ensures the line safe operation.

4. To implement the method of preventing falling from climbing towers in the construction of electric power projects, tie a polyester Nima rope with a diameter of 8mm on the existing safety belt belt, and place an aluminum alloy quick buckle ring every several meters on the rope. Install an aluminum alloy quick buckle ring on the main material within a few meters of the climbing tower. If the operator stumbles, the falling height is controlled within the mentioned several meters, and the distance between the aluminum alloy quick buckle rings is adjusted to control the falling height; The connection method between the quick buckle and the main material is to use the polyester Nima rope to connect the main material with a dead knot, and then lock one end of the dead knot with an aluminum alloy quick buckle. The waist of the worker; the parameters of the polyester Nima rope: the diameter of the nameplate is Φ8mm, and the instantaneous breaking force is 2400KG; the parameters of the aluminum alloy quick buckle ring: the instantaneous destructive force of the nameplate is 8KN.

In the construction and maintenance of power lines, it is often necessary to work at heights. Among them, the maintenance work of transmission lines is the most common. For a long time, operators have been doing it with bare hands, without any safety protection measures. Personal injury or death may occur if a load is missed or slipped. In recent years, in order to prevent such incidents, some units have installed full slides or fences on the towers, which have obvious effects but huge investment. At present, 90% of the iron towers of 220kV and below transmission lines in Liaoning Province do not have safety slide devices, and as a result, there were as many as 7 serious accidents caused by climbing iron towers without protection during 2010-2016. We have developed a kind of anti-falling device with less investment, good effect, economical and practical. At present, there is no development and application of this project in China. The main purpose of the above proposal is to provide a fall prevention device for climbing towers, so as to solve the problems of no protection for climbing towers and no protection for multiple people climbing towers during the operation of climbing towers on transmission lines. In order to achieve the above purpose, a climbing pole tower fall prevention device is provided. Its technical principle is to bind a Φ8MM polyester Nima rope on the existing safety belt belt, and place an aluminum alloy quick buckle on the rope every 5 meters. ring. The operator installs an aluminum alloy quick buckle ring on the main material every 5 meters of the tower. If the operator stumbles at this time, the falling height can be controlled within 5 meters. If you adjust the distance between the aluminum alloy quick buckle rings, you can even control the effect of the drop height (1 meter). Polyester Nima rope parameters: nameplate diameter Φ8MM, instant breaking force 2400KG. Parameters of aluminum alloy quick buckle ring: The instant destructive force of the nameplate is 8KN. The connection method of the aluminum alloy quick buckle ring and the main material: the polyester Nima rope is connected with the main material by a dead knot, and then the end of the dead knot is locked with an aluminum alloy quick buckle ring. The length of the polyester Nima rope should be appropriate, not too short or too long. The 50-meter-long diameter Φ8MM polyester Nima rope weighs about 2KG, and the weight of 10 aluminum alloy quick buckle rings is about 0.5KG. The aluminum alloy quick buckle ring is uniformly buckled on the waist of the operator when the personnel go up and down the pole tower. The beneficial effects mainly include the following five aspects: 1. Heat-resistant, anti-corrosion and anti-corrosion materials should be selected as the manufacturing material. 2. The operation of the climbing tower anti-falling device is flexible and convenient. 3. The anti-fall device of the climbing tower can completely replace the slideway of the iron tower. 4. The anti-fall device of the climbing tower can be controlled within 1m of the falling height. 5. Long service life. 6. When multiple people are working on the pole climbing tower, only the first person to climb the pole tower needs to carry the anti-falling safety rope of the pole climbing tower to ensure the safety of all climbing tower operators. The shape and structure of the device: The original components of the anti-fall device for the transmission line boarding tower include: 1 piece of 50-meter-long diameter Φ8MM polyester Nima rope, 10 aluminum alloy buckles, safety rope self-locking device (each person who climbs the tower carries one ). During the period from August 2014 to November 2015, the inventor used this device to carry out operations 26 times in total, and truly achieved the safety protection of the whole process of going up and down the tower. Formulated the "Technical Guidelines for Fall Prevention Devices for Climbing Towers" and compiled the "Guidelines for the Application and Maintenance of Fall Prevention Devices for Climbing Towers" to refine the technical guidelines and provide sufficient training for relevant personnel to ensure the safety of this technology Reliable implementation makes it more adaptable to the needs of operators climbing iron towers. The climbing tower anti-fall device replaces the disadvantages of the transmission line tower without speed difference protection device, and fills the gap in this field in China.

5. Implement the method of controlling the line inspection UAV in the field of electric power. Install a support platform on the body of the line inspection UAV. Install electronic control equipment and lifting steering gear on the support platform. After the line inspection UAV takes off, it can be controlled by remote control. The device controls the opening and closing of the lifting steering gear; the installation method of the supporting platform:

S1. Process the carbon fiber board, design and process the carbon fiber board according to the position of the tripod of the line patrol drone;

S2. Install the carbon fiber board and the line patrol drone body;

S3. Mount electronic equipment on the surface of the carbon fiber board;

S4. The carbon fiber plate is installed on the surface of the steering gear;

S5. After the line patrol UAV takes off, the beam of the steering gear is closed to pull heavy objects;

S6. The ground personnel control the horizontal movement of the steering gear beam through the remote control to control the loosening of the heavy objects.

After the plane takes off, the steering gear under the platform can lift heavy objects and open and close freely under the action of the remote control.

6. Implement the method of making 66kV-220kV docking spring type grounding wire clamp, the clamp includes two clamp splints arranged oppositely, and the clamp splint includes an integrated tip, groove and clip connected in sequence The inner opposite surface of the groove is a C-shaped clamp groove, and there are clip springs for clamping the circuit in each side clip groove. The two clip springs are arranged opposite to each other, and the clip springs pass through the shaft It is connected near the highest edge point of the C-shaped jaw. The clamping part has a protruding hinge part and is slotted inside. The hinge parts of the two opposite clamping parts are hinged by pins, and the pins are located inside the spring. The spring It is tightly pressed in the slot of the hinge part, and assembled according to the structure of the above-mentioned wire clip.

The above solution is used to solve the problem that the trigger torque of the ground wire of the traditional portable single-connected circlip clamp is too large, which cannot guarantee the success rate of the clamp clamp, which leads to the low success rate of the existing clamp installation, and the traditional portable single-connected circlip wire. The opening and closing torque of the ground wire clip is too large, it is difficult to operate with one hand, which brings about dangerous and hidden dangers. Under the same operating conditions, the trigger force is relatively large during the triggering process due to the small retreat distance of the traditional portable single-connecting circlip clamp ground wire clamp circlip. By lengthening the trigger arm of the circlip and changing the traditional single circlip into a double circlip, the trigger force can be further reduced and the success rate of clamping the wire can be improved. When installing the grounding wire, the operator needs to be at the crossarm of the tower, and the working conditions are greatly restricted. The adjustment of the traditional portable circlip clamp and the ground wire clamp requires both hands, which brings great inconvenience to the operator. The butt spring type grounding wire changes the structure of the traditional clamp and moves the spring shaft forward, making it easy to operate with one hand and improving the convenience of operation. A further solution is: the tip is formed by gradually increasing the cutting distance inwardly from the point flush with the outer wall of the groove. The distance between the point where the maximum width of the tip is flush with the outer wall of the groove is 5mm. The clamping portion has anti-slip lines, and the anti-slip lines are a combination of striped lines and rectangular lines. From the above scheme, the beneficial effects that can be obtained include economic benefits and safety benefits. In terms of economic benefits, this embodiment adopts the newly developed butt spring type grounding wire, reforms the traditional process, and simplifies the operation process. The safety of installing the grounding wire is guaranteed. It simplifies the operation procedure, shortens the time for installing the grounding wire, saves time and effort, and shortens the maintenance period. Calculated from the time saved in power outages, the hooking and docking of the spring-type grounding wire can save 3 to 10 minutes of working time in each maintenance operation. Taking 2015 as an example, there are 102 planned power outages for 66kV-220kV transmission lines per year. If the butt spring type grounding wire is used, the load outage time will be shortened by 5-22 hours, creating certain economic benefits for the enterprise.

From the point of view of safety benefits, the operation of opening the clamp can be completed with one hand when connecting the clamp-type grounding wire. To open the clamp, you only need to pinch the clamp vertically downward to complete the installation of the clamp spring. When installing the grounding wire, the trigger rate is lower. Great improvement, shortening the working time of personnel on the tower. At the same time, due to the material selection of the butt spring type grounding wire clamp, the electrical performance of the grounding wire is ensured while the lightness of the material is paid attention to. Each group (3 sets) of grounding wires is reduced by 0.42kg, which effectively reduces the load of personnel when climbing the pole tower. Physical expenditure of workers. The use of the butt spring type grounding wire not only effectively shortens the maintenance period, but also saves the physical strength of the operators, and effectively controls the safety risks on site.

8. Implement the manufacturing method of portable substation equipment snow remover, described snow remover comprises engine, the flexible shaft that is connected with the output of engine, described flexible shaft is connected with transmission shaft, and transmission shaft is connected with rotating brush to drive rotating brush Rotate, the transmission shaft is placed inside the insulation rod, the lower end of the insulation rod is a handle, the insulation rod is a glass fiber reinforced plastic insulation rod, the transmission shaft is a glass fiber reinforced plastic insulation transmission shaft, and a silicon Rubber waterproof umbrella skirt, the silicone rubber waterproof umbrella skirt is located above the upper end surface of the insulating rod, the flexible shaft is connected between the engine and the transmission shaft, the insulating rod is made of glass fiber reinforced plastic, and its surface is painted Mica powder and/or Teflon coating; assemble as described above for snow blower construction.

Because it is used for snow removal of substation equipment, the consideration of its insulation performance is an important factor. For this reason, the present invention selects FRP with better insulation performance as the insulation rod, and also fully considers the low temperature resistance of FRP. The low temperature resistance can reach minus 35 degrees Celsius. However, due to the distance and precision requirements of the substation equipment, the quality and volume of the snow blower need to be limited. For example, the thickness of FRP is generally 1-3mm. For FRP, which is a brittle material, it will be easily damaged, broken and corroded, that is, more brittle. In addition, it must be used in lower temperature weather in snowy weather, especially in Northeast China, where the temperature reaches minus 40 degrees Celsius or even lower. The resistance of FRP, snow or snow water is also corrosive, although it is lighter, it is very unfavorable for FRP in harsh environments. For this reason, the present invention is equipped with a silicone rubber waterproof umbrella skirt under the rotating brush, so The above-mentioned silicone rubber waterproof umbrella skirt is located above the upper end surface of the insulating rod, which enhances the shielding ability and reduces the possibility of snow water or snow contacting FRP. As a coordinated measure of protection measures, the service life of FRP is longer. Brushing mica powder, mica powder is a two-dimensional sheet crystal structure, which prevents the penetration of water vapor, improves the water vapor resistance and salt spray resistance of the paint film, and improves the anti-corrosion performance of the paint. Dense network structure of mica powder: arranged in parallel, overlapping each other, improving the strength of the paint film, resisting cracking, and improving the mechanical properties of the paint. Excellent chemical inertness of mica powder: acid resistance, alkali resistance, high temperature resistance, strong electrical insulation, improving the anti-corrosion stability and electrical insulation of coatings. Therefore, mica powder is an insulating material suitable for painting, and can block the penetration of water vapor, which can further ensure the insulation of FRP. More importantly, it can enhance the strength of FRP, enhance elasticity and toughness, and improve mechanical properties. The strength of FRP used in snow removal with a smaller thickness in ultra-low temperature environments has been significantly improved, and it is more suitable for use in snow machines as power transformation equipment, especially its temperature stability range is very large, which can be used at low temperatures. Some substation equipment is relatively sensitive to vibrations of certain frequencies, so the preferred mica powder of the present invention is coated with sericite, which can efficiently absorb vibration energy and weaken shock waves and sound waves. In addition, shock waves and sound waves are repeatedly reflected between mica chips, which also weakens their energy. The emission of the engine's sound waves in the FRP may be enhanced. In order to reduce the impact of the sound waves, this kind of mica powder coating is used. Except that the coating is all mica powder, as a solution, the mica powder coating is distributed brushing, which does not completely cover the FRP. PTFE, alternating with each other. The reason is that polytetrafluoroethylene is not brittle at an ultra-low temperature of -260°C, and can provide FRP with mechanical strength and low temperature resistance, and it is smooth and has particularly good insulation performance. , all of the coatings are polytetrafluoroethylene. During use, the portable substation equipment snow blower uses the S35 engine, the flexible shaft is connected to the FRP insulated transmission shaft inside the FRP insulating rod, and the front of the transmission shaft is connected to the rotating brush. The length of the flexible shaft is 1.5 meters, and the length of the insulating rod is 3 meters.
