Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of high-voltage discharge rods, and specifically relates to an anti-collision porcelain insulator high-voltage discharge rod. Background Art
[0002] The high-voltage discharge rod is made of a new type of insulating material, and has the characteristics of being able to be stretched and contracted, which is convenient for use in various outdoor high-voltage tests. Especially after a DC withstand voltage test, the accumulated charge on the test object is discharged to the ground to ensure personal safety. The high-voltage discharge rod is easy to carry, and also has the characteristics of being convenient, flexible, small in size, light in weight and safe.
[0003] After a high-voltage electrical equipment test (such as a DC withstand voltage test), a large amount of residual charge is usually stored. At this time, there is still a relatively high voltage on the equipment, and it is necessary to fully discharge the equipment for a long time or multiple times to ensure the safety of the test personnel. During discharging, usually first use the contact fitting at the front end of the discharge rod to slowly touch the test object whose test power supply has been disconnected, and after discharging through the discharge resistor, then use the hook directly connected to the grounding wire on the discharge rod to hook the test object to directly discharge and ground. Many power grid equipment are supported by porcelain insulators. For example, the incoming and outgoing lines of transformers often need to be connected and fixed through porcelain insulators, and the bodies of various high-voltage electrical equipment such as instrument transformers and lightning arresters also have porcelain insulators as supports. The quality of the porcelain insulators directly affects the safety of power grid equipment.
[0004] After retrieval, CN220857221U discloses an anti-collision porcelain insulator high-voltage discharge rod, which includes a discharge rod body and an anti-collision component arranged at the uppermost end of the discharge rod body; the anti-collision component extends a set distance outward from the center of the upper end of the discharge rod body to form a protection surface; the anti-collision component is made of a soft material, and the anti-collision component is higher than the discharge rod body by a set distance and is spaced from the grounding end of the discharge resistor on the discharge rod body by a set gap. An anti-collision component is arranged on the upper part of the discharge rod body, which can form a protection mask at the upper end of the discharge rod. When discharging, the anti-collision component can first contact the porcelain insulator at the discharging part, thus playing a buffering role, discharging most of the impact force, greatly reducing the possibility of the discharge rod colliding with the porcelain insulator of the equipment during use, and being able to protect the porcelain insulator on the equipment to the greatest extent.
[0005] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects: in the above device, an anti-collision component made of a soft material is arranged at the end of the rod body of the discharge rod to play an anti-collision buffering role, reducing the possibility of the discharge rod colliding with the porcelain insulator of the equipment during use. However, the setting of the anti-collision component can only play an anti-collision buffering role at the end position. If the staff operates improperly during the work, the rod body of the discharge rod is still relatively easy to collide with the porcelain insulator of the power grid equipment, resulting in cracks in the porcelain insulator, affecting the mechanical strength and dielectric strength of the porcelain insulator, and even causing partial discharge or even breakdown and oil leakage.
[0006] In view of this, the present utility model is hereby proposed. Content of the Utility Model

The discharge resistance grounding end is electrically connected to the discharge resistance, and the direct grounding end and the discharge resistance are electrically connected.
[0014] The present utility model has the following beneficial effects compared with the prior art:
[0015] In this utility model, by providing a collision-proof end plate made of insulating soft silicone rubber material at the end of the discharge rod body, a protective mask can be formed at the end of the discharge rod body. When performing a discharge operation, the collision-proof end plate first contacts the porcelain bottle at the discharge site, which can play a buffering role, thereby discharging most of the impact force, reducing the possibility of the discharge rod colliding with the porcelain bottle of the equipment during use, and being able to protect the porcelain bottle on the equipment to the greatest extent. Moreover, through the provided first protective sleeve and second protective sleeve made of insulating soft materials, when the operator operates improperly, the first protective sleeve and the second protective sleeve can play a good buffering role when contacting the porcelain bottle at the discharge site, avoiding the direct contact between the discharge rod body and the porcelain bottle and causing damage to the porcelain bottle, and reducing the probability of equipment damage.

[0024] As Figures 1 to 4 shown
[0025] An anti-collision porcelain insulator high-voltage discharge rod, comprising a discharge rod body 1. A connecting column 2 is installed at the end of the discharge rod body 1. Both the discharge rod body 1 and the connecting column 2 are made of insulating materials. An anti-collision end plate 5 is fixedly installed at the end of the connecting column 2. A discharge resistance grounding end 3 is arranged at the end of the discharge rod body 1. The discharge resistance grounding end 3 is located on the left side of the connecting column 2. The discharge resistance grounding end 3 is the front contact fitting of the discharge rod, used to contact the equipment to be discharged to achieve the discharge of the equipment to be discharged. The direct grounding end 4 is used for grounding. There is a gap between the discharge resistance grounding end 3 and the connecting column 2. The anti-collision end plate 5 is made of insulating soft silicone rubber material. There is an activity space between the anti-collision end plate 5 and the discharge resistance grounding end 3. By arranging the anti-collision end plate 5 made of insulating soft silicone rubber material at the end of the discharge rod body 1, a protective mask can be formed at the end of the discharge rod body 1. When discharging, the anti-collision end plate 5 first contacts the porcelain insulator at the discharge part, which can play a buffering role, thus discharging most of the impact force and reducing the possibility of the discharge rod colliding with the porcelain insulator of the equipment during use. A first protective sleeve 8 is fixedly arranged on the outer wall of the right side of the discharge rod body 1. A second protective sleeve 9 is fixedly connected to the outer wall of the right side of the connecting column 2. Both the first protective sleeve 8 and the second protective sleeve 9 are arc-shaped structures. Both the first protective sleeve 8 and the second protective sleeve 9 are made of insulating soft materials. When the staff operates improperly, when the first protective sleeve 8 and the second protective sleeve 9 contact the porcelain insulator at the discharge part, they can play a good buffering role to avoid the discharge rod body 1 directly contacting the porcelain insulator and causing damage to the porcelain insulator.
[0026] In the specific implementation manner, a protective circular plate 10 is fixedly installed at the end of the discharge rod body 1 far away from the connecting column 2. An insulating handle 11 is fixedly arranged on one side of the protective circular plate 10. The protective circular plate 10 is used to define the grasping position of the discharge rod and standardize the use operation of the discharge rod, so that the staff can firmly hold the insulating handle 11, thereby realizing safe operation. The direct grounding end 4 is fixedly arranged on the left side of the discharge rod body 1. A grounding wire 6 is connected to the direct grounding end 4. A grounding clamp 7 is connected to the end of the grounding wire 6. The direct grounding end 4 and the grounding wire 6 are electrically connected. The grounding wire 6 and the grounding clamp 7 are electrically connected. A discharge resistance is arranged inside the discharge rod body 1. The discharge resistance grounding end 3 is electrically connected to the discharge resistance. The direct grounding end 4 and the discharge resistance are electrically connected. In a high-voltage test, when it is necessary to discharge the test object, the grounding clamp 7 can be connected to the actual grounding body to achieve the discharge of the equipment. The grounding body is specifically a grounding angle steel, a grounding iron, etc. set on site. The staff first slowly touches the test object with the power supply of the test disconnected with the discharge resistance grounding end 3 at the front end of the discharge rod body 1. After discharging through the discharge resistance, through the set direct grounding end 4, grounding wire 6 and grounding clamp 7, direct discharge and grounding are carried out.
[0027] The implementation principle of the anti-collision porcelain insulator high-voltage discharge rod in this embodiment is as follows:
[0028] During actual use, an anti-collision end plate 5 made of insulating soft silicone rubber material is provided at the end of the discharge rod body 1, which can form a protective mask at the end of the discharge rod body 1. When discharging operation is carried out, the anti-collision end plate 5 first contacts the porcelain bottle at the discharge part, which can play a buffering role, thereby discharging most of the impact force, reducing the possibility of the discharge rod colliding with the porcelain bottle of the equipment during use, and being able to protect the porcelain bottle on the equipment to the greatest extent. And through the first protective sleeve 8 and the second protective sleeve 9 made of insulating soft materials, when the operator operates improperly, the first protective sleeve 8 and the second protective sleeve 9 can play a good buffering role when contacting the porcelain bottle at the discharge part, avoiding the direct contact between the discharge rod body 1 and the porcelain bottle and causing damage to the porcelain bottle, reducing the probability of equipment damage. During the high-voltage test, when it is necessary to discharge the test object, the grounding clip 7 can be connected to the actual grounding body to achieve the discharge of the equipment. The grounding body is specifically the grounding angle steel, grounding iron, etc. set on the site. The operator first slowly touches the test object with the test power supply disconnected with the grounding end 3 of the discharge resistor at the front end of the discharge rod body 1. After discharging through the discharge resistor, through the directly grounded end 4, the grounding wire 6 and the grounding clip 7, direct discharge and grounding are carried out.
