Description

Technical field:

[0001] The present invention relates to the research, development and design field of detachable hanging type gapless lightning arrester, and in particular to a live working fully insulated detachable hanging type gapless lightning arrester device. Background technology:

[0002] The traditional national standard HY5W composite sheathed metal oxide gapless lightning arrester is currently the most widely used lightning protection product for line lightning protection. Since the gapless lightning arrester bears the system voltage for a long time during system operation, there is a risk of aging and damage, and it needs regular inspection and replacement. The main disadvantage is that once the lightning arrester is damaged, it can only be replaced after power is cut off. If there is another lightning strike or overvoltage during the replacement period, it will no longer be able to play a protective role. The use of a boom truck for live replacement will consume a lot of manpower and material resources and is restricted by the terrain.

[0003] Another drop-out arrester disclosed in CN201320171068.7 is a modified zinc oxide arrester installed on the drop-out mechanism of the original drop-out fuse, so that the arrester can be inspected, repaired and replaced with the help of an insulating operating rod without interrupting power supply. Its disadvantages are that the drop mechanism has a complex structure, high processing cost, and troublesome assembly; the main electrical components are exposed and easy to age, easily pollute and short-circuit, affecting the overall insulation design process; when the lightning arrester body is closed, the elastic sheet is compressed to store energy, and is prone to fatigue failure. When the disconnector itself fails, the drop mechanism will fail and the line lightning protection will be unprotected; the drop mechanism is also installed outdoors on the line crossarm. The lightning arrester has a relatively short lifespan among overhead line equipment and is easily damaged. Inspection, maintenance, and replacement are currently prominent problems that are more troublesome in the power sector, especially the exposed part of the zinc oxide lightning arrester is made of silicone rubber, and silicone rubber products are prone to aging and brittle cracking in the natural environment, and birds tear and peck, which reduces the service life. There are many electrical connection points, that is, there are many electrical fault points, which also affects the overall line insulation and appearance; although the damaged lightning arrester body can be removed and replaced with power when damaged, the drop-type lightning arrester must be equipped with a disconnector. The lightning arrester cannot be used without a disconnector, and the integration is not high and it is relatively bulky.

[0004] Another type is the chamber arrester, which mainly moves the zinc oxide arrester body from outdoors to indoors to reduce the impact of the natural environment on the arrester body; the arrester can be inspected, repaired and replaced with the help of an insulating operating rod. Although it has the function of quickly replacing the arrester body during live operation, it does not have the function of quickly and easily installing and disassembling the arrester device during live operation; the porcelain jacket is bulky and fragile. Once the arrester fails and explodes, the flying metal oxides together with the fragile porcelain jacket can easily harm other electrical equipment and passers-by, and it is inconvenient to install it at a high point on the line; there is no sealing design between the arrester body and the cavity, and it is affected by the environment during long-term operation. Under harsh climatic conditions, water vapor and salt can easily enter the chamber and cause failures, especially in coastal areas with relatively high salt fog concentrations; due to the arrester There is no sealing between the main body and the cavity, and the lightning arrester body needs to increase the insulation height and creepage skirt distance, which increases the weight. The lightning arrester is easy to fall due to its own weight, which also causes the overall cost to be too high; there is no electrical grounding device, and it is inconvenient to hang the grounding wire. Pulling the lightning arrester body directly out of the cavity can easily cause arcing. The installation of the lightning arrester requires a special lightning arrester crossarm, which makes the line unsightly and increases the cost. The twist-on insulation cover that is easily blown off by the wind cannot achieve true sealed and fully insulated. It is difficult to install intelligent detection devices in conjunction with smart grids. Summary of the invention:

[0005] The purpose of the present invention is to overcome the above shortcomings, and aims to study a lightning arrester device that can be quickly installed or disassembled during live working with the help of an insulating operating rod, and can also quickly separate and repair, plug and unplug and replace the lightning arrester body during live working, and is equipped with an electrical grounding rod for convenient hanging of the grounding wire, and can hang the lightning arrester device installed on the original iron crossarm of the line. The insulating cavity is molded with a lightweight hard PC insulating material with high strength and high electrical performance, good explosion-proof and aging resistance, and greatly reduces the weight of the entire device. The topmost umbrella skirt is larger than all the umbrella skirts below. The lightweight insulating cavity with large and small umbrella designs is rain-proof and anti-fouling. The inner wall and the lightning arrester body are fully insulated and sealed above and below, which will not affect the overall electrical performance of the lightning arrester when operating under harsh natural conditions.

[0006] To achieve the above-mentioned object, the present invention provides a fully insulated, detachable, hanging, gapless lightning arrester device for live working, comprising: a piercing, detachable insulating wire clamp 1, a drain wire 2, an upper contact piece 3, a hanging connection plate 4, a lightweight insulating cavity 5, a live working mounting bracket 6, an upper contact 7, an upper insulating waterproof piston ring 8, a lightning arrester body 9, a contact ring 10, a lower insulating waterproof piston ring 11, a separator 12, a sealing ring 13, a pile head insulating cover 14, a drain wire connecting pile head sealing ring 15, a drain wire connecting pile head 16, an electrical test grounding rod 17, a contact piece fixing ring 18, a contact piece 19, an elastic tension spring 20, and the like. The device is mainly used to protect medium-voltage distribution network equipment from lightning strikes and operational overvoltages. An insulating operating rod can be used to install a bracket 6 and a piercing and detachable insulating wire clamp 1 for live working. The insulated wire does not need to be stripped when using the piercing and detachable insulating wire clamp 1. The three thorns inside the wire clamp will pierce the inside of the wire to ensure a stable electrical connection without damaging the insulation layer of the wire. The device can be installed or removed during live working, and the insulating operating rod can be used to plug in and out the separator 12 and the lightning arrester body 9 and other assemblies during live working for rapid maintenance and replacement, reducing the inconvenience caused by power outages and improving the efficiency of installation and maintenance; the electrical testing grounding rod 17 is convenient for testing the grounding wire and grounding protection of equipment maintenance and construction when live. It is suspended and installed on the original crossarm 21, omitting the lightning arrester crossarm and the installation chamber lightning arrester clamp, saving costs, increasing the line corridor and aesthetics, and creating conditions for live working.

[0007] One end 4.2 of the hanging connecting plate 4 made of metal material is installed on the top of the light composite insulating cavity 5 and screwed and tightened. The connection is sealed with a sealing ring to prevent moisture and salt from entering the light insulating cavity 5 and destroying the sealing environment.

[0008] The other end 4.3 of the bent hanging connecting plate 4 is screwed onto the sides 6.2 and 6.3 of the live working mounting bracket 6, making it easy for the insulating operating rod to place the live working mounting bracket 6 on the existing cross arm 21 of the line, saving one cross arm and making the line corridor more beautiful. The insulating operating rod is used to tighten the ring bolt 6.1. The live working mounting bracket adopts an anti-loosening design structure at 6.4 to prevent loosening over time. Live working can be achieved with the initial installation of the lightning arrester.

[0009] The lightweight insulation chamber 5 is a tower-shaped structure with large and small sheds that meet creepage distance requirements. The top shed is larger than all the lower sheds, acting as a rain curtain and dirt shield, preventing icicles from adhering to other sheds, and also providing a certain degree of snow protection, making the arrester more reliable in natural disasters. The large and small sheds, combined with the use of a circular transition at the base, enhance the chamber's strength and provide explosion protection, preventing damage to the arrester and fragments from blasting. If an arrester fails and explodes, the flying metal oxides, combined with the fragile porcelain jacket, can easily cause a ground fault in the line, harming other electrical equipment and passersby. Installation at high points on the line is also inconvenient.

[0010] An insulating and waterproof piston ring 8 is installed on the upper part of the lightning arrester body 9 for sealing. It is made of insulating composite material and has a structural design similar to that of a car piston. The surface of the lightning arrester is bonded with a hard insulating material, and two grooves are opened on it to install soft rubber rings, which play both a sealing and insulating role to prevent the high voltage at the top of the lightning arrester body 9 from creeping from the inside of the cavity. Because the inside of the light insulating cavity 5 is a smooth surface, creeping will be carried out from the outside of the light insulating cavity. The insulating and waterproof piston ring 8 is used to seal the inside of the cavity and the lightning arrester body 9.

[0011] The lower part of the contact ring 10 is sealed with a lower insulating waterproof piston ring 11 to prevent erosion by water vapor and salt mist.

[0012] The upper and lower structures of the light insulating cavity 5 have a certain taper, which makes the sealing structure between the light insulating cavity 5 and the arrester body 9 better. The structure of the light insulating cavity 5 is narrow at the top and wide at the bottom, so that the arrester body 9 is inserted into the light insulating cavity 5 more and more tightly, and the bottom is sealed with a lower insulating waterproof piston ring 11.

[0013] The drainage line connection pile head 16 is sealed with a sealing ring 15 to prevent affecting the sealing between the light insulating cavity 5 and the arrester body 9. The end of the drainage line 2 is crimped onto the drainage line connection pile head 16, and the pile head insulation cover 14 is used to cover the entire body to prevent wind and rain. The drainage line connection pile head 16 plays a multiple connection role, screwing the light insulating cavity 5 with the internal contact piece fixing ring 17, leaving the drainage line connection pile head 16 to connect the drainage line 2, and the middle is sealed with a sealing ring 15.

[0014] The end of the drainage line 2 is crimped on the piercing type detachable insulating wire clamp 1 made of metal material with good conductive performance, and is tightly covered by the pile head insulating cover 1.5 made of soft and elastic rubber material to prevent the invasion of wind, rain and moisture. The operating rod can be used for live operation on the installation hanging ring 1.4. The piercing type detachable insulating wire clamp 1 can be conveniently tightened on the high-voltage wire. Tightening the ring bolt 1.3 drives the slider 1.9 to tighten the insulated wire. The three thorn teeth 1.2 will evenly penetrate the insulated wire to ensure a stable electrical connection. The length of the thorn teeth has been verified through many tests. It ensures sufficient electrical connection without damaging the wire. The puncture method simplifies the installation of the wire without peeling, does not damage the insulation layer of the wire, reduces exposed points, and is conducive to achieving full insulation of the line.

[0015] There are two screw holes on the side of the contact ring 10, which can be screwed to the separator 12 to form a whole with the contact ring 10. When replacing and repairing the live working fully insulated detachable hanging type gapless lightning arrester device, it is only necessary to clamp the operating locks at both ends of the separator 12 to drive the lightning arrester body 9 to be plugged in and replaced.

[0016] The contact piece fixing ring 18 is made of a metal material with good conductive properties, and screw holes are evenly distributed at the bottom to fix the contact piece 19. The contact piece 19 made of a metal material with good conductive properties and good elasticity is in close, elastic and constant electrical contact with the contact ring 10 to ensure normal current flow.

[0017] The electrical testing grounding rod 17 passes through the light insulating cavity 5 and is screwed to the contact piece fixing ring 18. When the line equipment needs to be repaired or replaced, the ground wire is first connected through the electrical testing grounding rod 17. During the construction operation, the electrical testing grounding rod 17 facilitates the hanging of the ground wire and provides a guarantee for the safety of the construction.

[0018] The elastic tension spring 20 is wrapped around the contact piece 19 to tighten it, so as to prevent the elasticity of the contact piece from deteriorating over time.

[0019] The outer diameter of the lower end of the arrester body 9 closely matches the inner wall of the contact ring 10. The metal electrode at the bottom of the arrester body 9 and the end of the contact ring 10 are screwed together for tight electrical contact. The bottom end of the arrester body 9 is tapered, leveraging the flexibility of the silicone rubber jacket to ensure a more compact and secure connection, and the screw connection is tightly aligned. The contact ring 10 and separator 12 are connected as a whole via a tapered tightening seal. The separator 12 is made of high-strength, UV-resistant PC insulating material. The lower portion of the separator is tapered and guided, with a symmetrical cylindrical plug-in and pull-out lock at the waist. A lower insulating and waterproof piston ring 11 is tightly fitted between the lower end of the contact ring 10 and the separator 12. When the arrester body assembly is inserted, the lower insulating and waterproof piston ring 11 is driven. Made of soft and elastic rubber, its outer edge dynamically mates with the inner wall of the lightweight insulating cavity 5 to provide a waterproof and insulating seal, protecting it from moisture and salt spray erosion. The lightweight insulating cavity 5 is injection molded from UV-resistant PC rigid insulating material, and the base arc of the shed skirt is excessively reinforced.

[0020] The end of the drainage wire 2 and the drainage wire connecting pile head 1.6 on the puncture-type detachable insulated wire clamp 1 are crimped into a whole, and are covered as a whole with a pile head insulation cover 1.5 for sealing. The drainage wire connecting pile head 1.6 on the puncture-type detachable insulated wire clamp 1 is screwed into a whole with the puncture-type detachable insulated wire clamp 1 shell 1.10, and a sealing ring 1.7 is placed between them to prevent corrosion caused by moisture and salt entering the connection over time.

[0021] The outer surface 1.15 of the ring bolt 1.3 on the piercing type removable insulating wire clamp 1 is made of a hard insulating material to play an insulating protection role. The outer surface 1.13 of the slider 1.9 on the piercing type removable insulating wire clamp 1 is made of a soft insulating material to ensure close contact with the insulated wire. The outer surface 1.14 of the shell 1.10 on the piercing type removable insulating wire clamp 1 is made of a hard insulating material to play an insulating protection role. The outer surface of the mounting ring 1.4 on the piercing type removable insulating wire clamp 1 is made of a hard insulating material to play an insulating operating rod operation role. The screw 1.8 and the outer sleeve 1.12 are made of soft insulating material. They are hung on the installation hanging ring 1.4 with an insulating operating rod and placed on the insulated wire. Tightening the annular bolt 1.3 drives the internal pressure block 1.9 port to automatically close, and the insulated wire is tightly fixed with the upper end shell 1.10. The screw outer sleeve 1.12 is made of soft insulating material. When the annular screw 1.3 is twisted, the screw outer sleeve 1.12 will expand and contract. There are three thorn teeth 1.2 on the piercing and detachable insulating wire clamp 1 that pierce into the inside of the insulated wire. The three thorn teeth ensure a stable electrical connection and have a good flow rate in the event of overvoltage lightning.

[0022] Live working fully insulated detachable hanging type gapless lightning arrester device, the electrical grounding rod 17 passes through the light insulating cavity 5 and is screwed to the contact piece fixing ring 18. When installing, removing and plugging in the lightning arrester body 9, there is no need to hang the ground wire, and it can be plugged in and replaced. Description of the drawings:

[0029] Figure 7 This is a structural diagram of the piercing type detachable insulating wire clamp of the present invention. Specific implementation method:

[0030] The live working fully insulated detachable hanging type gapless lightning arrester device of the present invention comprises: a puncture-type detachable insulating wire clamp 1, a drainage wire 2, an upper contact piece 3, a hanging connecting plate 4, a light insulating cavity 5, a live working mounting bracket 6, an upper contact 7, an upper insulating waterproof piston ring 8, a lightning arrester body 9, a contact ring 10, a lower insulating waterproof piston ring 11, a separator 12, a sealing ring 13, a pile head insulating cover 14, a drainage wire connecting pile head sealing ring 15, a drainage wire connecting pile head 16, an electrical testing grounding rod 17, a contact piece fixing ring 18, a contact piece 19, an elastic tension spring 20, and the like.

[0031] The arrester body 9 is inserted into the light insulating cavity 5, and the hanging connecting plate 4 is screwed on the top of the light insulating cavity 5. The hanging connecting plate 4 is screwed in a bent shape on the live working mounting bracket 6. One end of the drainage line 2 is screwed on the connecting pile head 16, and the other end is screwed on the puncture-type detachable insulating wire clamp 1, that is, a set of live working fully insulated detachable hanging type gapless arrester device is assembled. During installation, first insert the insulating operating rod into the separator 12 on both sides to operate the lock to lift the entire device, and install the live working mounting bracket 6 on the existing crossarm 21 of the line, and use another operating rod to extend into the annular screw hole 6.1 on the live working mounting bracket 6 and tighten it, and then use the insulating operating rod to extend into the mounting port 1.4 to install the puncture-type detachable insulating wire clamp 1 on the conductor to complete the installation. The initial installation of the arrester can achieve live working.

[0032] This product is primarily used for overvoltage protection at the end of line equipment. An insulated operating rod allows live installation and removal of the device. The arrester body (9) within the lightweight insulated cavity (5) can be quickly repaired, plugged in, or replaced using the insulated operating rod, minimizing the inconvenience of power outages and improving installation and maintenance efficiency. The grounding rod (17) facilitates the connection of ground wires. Suspended installation on existing crossarms reduces the number of arrester crossarms, increasing the line corridor and enhancing aesthetics.

[0033] When the line is struck by lightning, the lightning current passes through the thorn teeth 1.2 on the piercing and detachable insulating wire clamp 1 to the drainage line 2, and the lightning current reaches the arrester body 9 along the drainage line 2. Under high voltage, the arrester body 9 made of zinc oxide material is in a low resistance state. The lightning current is conducted to the grounding wire through the hanging connecting plate 4 and the live working mounting bracket 6. When the lightning current is discharged to the ground, the arrester body 9 returns to a high resistance state. Since there is no gap, the arrester also has a good prevention and control effect on operational overvoltage.

[0034] When the arrester is damaged, the operating locks on both sides of the separator 12 are clamped with an insulating operating rod to pull out the arrester body 9, and then the operating rod is used to replace the new arrester body 9 to continue operation. It can be directly plugged in and out without hanging a ground wire. The arrester on the traditional line can only be replaced after the power is cut off, or it consumes a lot of manpower and material resources to replace it by hanging a ground wire. During the damage period, the arrester cannot protect the line, and power outages will cause certain economic losses. Therefore, live working is particularly important.

[0035] Power supply reliability has become an assessment indicator for power companies. Live working on long-distance lines in mountainous areas or densely populated paddy fields has always been a technical challenge. How to effectively reduce the number of power outages and reduce labor intensity? The live working fully insulated detachable hanging type gapless lightning arrester device can be used for live working during the first installation. The line insulation level is improved, and the lightning arrester nodes can be fully insulated. The use of the live working mounting bracket 6 makes the live working fully insulated detachable hanging type gapless lightning arrester device more stable and reliable, especially the bending and clamping design at 6.5 of the upper end live working mounting bracket 6 can make the bracket more secure in the horizontal direction to avoid slipping.

[0036] The top of the lightweight insulating cavity 5 is an electrical connection point, which also serves to support and suspend the entire cavity. The lightweight insulating cavity 5 is made of excellent PC material, which has excellent electrical insulation performance, high mechanical strength, excellent explosion-proof performance, and good waterproof and stain-resistant performance. It is a good insulating engineering material that greatly reduces the weight of the overall device. Once an old lightning arrester fails and explodes, the flying metal oxides together with the fragile porcelain jacket can easily cause a line grounding fault, harming other electrical equipment and passers-by. It is inconvenient to install it at a high place on the line.

[0037] According to national standards, the design of the arrester shed is a structure that is larger at the top and smaller at the bottom. The lightweight insulating cavity 5 is designed so that the top shed is the largest, which can well protect the sheds below. Tests have shown that the largest first shed can better prevent surface flashover, especially for blocking electrical channels formed by rain curtains, icicles, and drifting snow.

[0038] The lightweight insulating cavity 5 is made of hard and high-strength PC material, which can prevent birds from tearing and pecking at it. Especially in recent years, as the environment has improved and the number of birds has increased, they have caused certain damage to the operation of the line.

[0039] This design is intended to: reduce weight and enhance explosion-proof performance; improve line insulation level; achieve rapid live-line operation, and the installation, disassembly, maintenance and replacement of the product do not require climbing poles, and can be completed on the ground with the help of insulating operating poles, reducing labor intensity and improving the safety of operation and maintenance; the use of the electrical grounding pole is convenient for hanging the ground wire, and after hanging the ground wire, the line equipment can be directly inspected and replaced. During installation, the live-line operation puncture method is used to connect the wires, which does not damage the insulation layer of the wires, and is conducive to achieving full insulation of the line; the lightning arrester body 9 is installed in the insulating cavity 5 to avoid the invasion of sunlight, rain, and haze, and the lightning arrester is more stable and has a longer service life.
