Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology for power distribution equipment, specifically to a lightning protection device for outdoor power distribution equipment with a surge arrester. Background Technology

[0002] Electrical equipment is a general term for equipment in a power system, including high-voltage switchgear, generators, transformers, power lines, circuit breakers, low-voltage switchgear, distribution panels, switch boxes, control boxes, etc.

[0003] Power distribution equipment is often installed outdoors as needed. However, in actual use, the presence of rainy days can lead to lightning strikes on the equipment, causing damage to the equipment and related electrical appliances. To prevent the equipment from being struck by lightning, surge arresters are often connected in parallel with the equipment. Although surge arresters can transfer the electrical energy of lightning strikes to the ground, in actual use, because they are installed outdoors, the accompanying milliammeter is easily corroded by rainwater and damaged, making it impossible to determine the condition of the surge arrester, thus affecting its use and failing to meet actual needs.

[0027] The lightning protection device for outdoor power distribution equipment with surge arrester provided in this embodiment, such as Figures 1-5 As shown, it includes: a mounting rod 1, a lightning rod 2 installed at the top of the mounting rod 1, a lead wire 6 inserted inside the mounting rod 1, a protective mechanism 3 installed on the outside of the mounting rod 1, and a surge arrester body 4 installed on the inside of the protective mechanism 3. The mounting rod 1 is used to install the lightning rod 2 and the protective mechanism 3 on one side of the power distribution equipment to protect the power distribution equipment from damage caused by lightning strikes during actual use. The lightning rod 2 actively diverts lightning into the ground to prevent lightning from striking the power distribution equipment. The protective mechanism 3 is used to install the surge arrester body 4 and the milliammeter 11. The surge arrester body 4 is used to transfer electrical energy to the ground after the equipment is struck by lightning to prevent damage to the equipment and electrical appliances. At the same time, it protects the milliammeter 11 from being damaged by rainwater erosion when the equipment is installed outdoors, which would affect the subsequent monitoring of the surge arrester body 4.

[0028] The protective mechanism 3 includes a mounting shell 301 disposed on the outside of the mounting rod 1. A partition 306 is fixedly installed inside the mounting shell 301. Receiving grooves 309 are provided on the top and bottom of the mounting shell 301 and inside the partition 306. The surge arrester body 4 passes through the receiving grooves 309 into the interior of the mounting shell 301. A milliammeter 11 is fixedly installed on the right side of the bottom of the surge arrester body 4. The milliammeter 11 extends into the interior of the mounting shell 301 and is located below the partition 306. The mounting shell 301 is used to install and accommodate the surge arrester body 4. The partition 306 is used to separate the inner cavity of the mounting shell 301 to accommodate the milliammeter 11, and at the same time, to isolate the milliammeter 11 from the external environment to prevent rainwater from corroding the milliammeter 11 and causing it to be damaged.

[0029] A rubber sealing strip 305 is inserted inside the partition 306. The rear side of the rubber sealing strip 305 contacts the surge arrester body 4. Two screws are threaded inside the partition 306, and the top of the screws contacts the bottom of the surge arrester body 4. The rubber sealing strip 305 is designed to prevent rainwater from entering the lower part of the partition 306 through the front side of the mounting shell 301 and the receiving groove 309, which would cause corrosion and damage to the milliammeter 11. At the same time, the milliammeter 11 is located on the right side of the receiving groove 309, which further prevents rainwater from entering and corroding the milliammeter 11.

[0030] A sealing door 307 is hinged to the front of the mounting housing 301. An acrylic plate 308 is embedded inside the sealing door 307. The sealing door 307 is used to seal the space at the bottom of the partition 306 to protect the milliammeter 11. At the same time, the acrylic plate 308 facilitates personnel to observe the milliammeter 11.

[0031] A pin 304 is fixedly installed on the right side of the sealing door 307. The pin 304 is inserted into the interior of the mounting housing 301. The pin 304 is provided to connect the sealing door 307 and the mounting housing 301, so as to prevent external rainwater from corroding the measuring milliammeter 11 when the sealing door 307 is opened during actual use.

[0032] Two sets of annular fixing brackets 302 are sleeved on the outer side of the mounting rod 1. A third bolt 303 is inserted on both sides of the annular fixing bracket 302. The front side of the annular fixing bracket 302 is fixedly connected to the rear side of the mounting shell 301. The annular fixing bracket 302 and the third bolt 303 are used to fix the mounting shell 301 to the outer side of the mounting rod 1, thereby realizing the installation of the surge arrester body 4.

[0033] The top of the mounting rod 1 is provided with a mounting base 5, the top of the mounting base 5 is fixedly connected to the bottom of the lightning rod 2, the mounting base 5 has a mounting groove 7 inside, and a first bolt 8 is inserted into the mounting groove 7. The bottom of the first bolt 8 extends into the interior of the mounting rod 1 and is connected to the mounting rod 1 by a threaded rotation. The mounting base 5, the mounting groove 7 and the first bolt 8 are used to fix the lightning rod 2 to the top of the mounting rod 1 so as to guide the lightning in the future.

[0034] An arched connecting frame 9 is installed at the bottom of the lightning rod 2. The top of the lead wire 6 passes through the interior of the arched connecting frame 9. A second bolt 10 is inserted inside the arched connecting frame 9 and the lead wire 6. The arched connecting frame 9 and the second bolt 10 are used to realize the electrical connection between the lead wire 6 and the lightning rod 2, so as to lead the electrical energy to the ground and discharge it to avoid damage to the equipment.

[0035] In use, the mounting rod 1 is pre-embedded to one side of the power distribution equipment. After the embedding is completed, the lead wire 6 is inserted into the interior of the arched connecting frame 9. At the same time, the lead wire 6 and the arched connecting frame 9 are fixed by the second bolt 10. After installation, the lightning rod 2 and the lead wire 6 are lifted and the lead wire 6 is inserted into the interior of the mounting rod 1. The lightning rod 2 is placed on top of the mounting rod 1. After placement, the first bolt 8 is removed and inserted into the mounting groove 7 and threadedly connected to the mounting rod 1 to complete the installation of the lightning rod 2 and the mounting rod 1. The mounting shell 301 is then connected to the mounting rod 1 by the annular fixing frame 302 and the third bolt. Bolt 303 is fixed to the outside of mounting rod 1. The pin 304 is pulled out from the inside of mounting housing 301, and the sealing door 307 is opened. The surge arrester body 4 and the test milliammeter 11 are inserted into the inside of mounting housing 301 through the receiving groove 309. The surge arrester body 4 is fixed into the inside of mounting housing 301 with screws. After fixing, the rubber sealing strip 305 is inserted into the receiving groove 309. Then the sealing door 307 is closed and the pin 304 is inserted into the inside of mounting housing 301. Finally, the surge arrester body 4 is connected to the equipment through wires.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
