Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of high voltage protection, and in particular to an isolation and protection frame suitable for high voltage electrical equipment. Background Technology
[0002] In my country's construction safety standards, the "Technical Specification for Temporary Power Supply Safety at Construction Sites" (JGJ46-2005) clearly stipulates the protection of high-voltage lines. Specifically, if the distance between the tower crane and the high-voltage line is less than the specified minimum safe distance (3 meters vertically and 2 meters horizontally), insulation and protective measures must be taken.
[0003] Existing high-voltage electrical isolation facilities include poles, which are installed next to utility poles and topped with protective shields and insulating connectors. However, when debris, such as fallen leaves, falls from above the high-voltage lines, there is a risk of contact with the lines, potentially causing a short circuit or even a fire. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing high-voltage electrical isolation and protection frames, which cannot prevent debris falling from high-voltage poles from contacting high-voltage lines, and to provide an isolation and protection frame suitable for high-voltage electrical equipment.
[0005] This utility model provides an isolation and protective frame suitable for high-voltage electrical equipment, comprising:
[0006] Protective tie rod;
[0007] A protective barrier is connected to a protective tie rod, the protective tie rod is used to be installed above the high-voltage power pole, and the width of the protective barrier is greater than the crossarm of the high-voltage power pole;
[0008] An insulating protective component, which is fitted over the protective pull rod;
[0009] A monitoring device is disposed on the protective barrier, and the monitoring device includes an infrared ranging sensor;
[0010] An alarm device is connected to the protective barrier, and the alarm device and the monitoring device are signal-connected.
[0011] The width of the protective barrier refers to its length along the crossarm of the high-voltage pole. The crossarm of a voltage-sensitive pole is the horizontal part at the top of the pole, used to support and secure the power lines.
[0012] Protective tie rods are installed beside high-voltage power poles. Protective barriers are installed above the high-voltage power poles, with a width greater than the length of the crossarm. This allows the barriers to cover the high-voltage lines fixed to the crossarm. When debris falls from above the power pole, the barriers prevent it from contacting the high-voltage lines, minimizing the risk of short circuits or even fires. Insulating protective sleeves are fitted over the tie rods to ensure the safety of personnel and equipment. Monitoring devices are equipped with infrared distance sensors. When the monitoring device detects an object within a threshold distance of the high-voltage power pole, it sends a signal to the alarm device. The alarm device receives the signal and issues an alarm, minimizing the risk of tower cranes accidentally contacting the high-voltage lines or personnel climbing over the protective barriers.
[0013] Preferably, a walking device and a locking device are provided between the protective barrier and the protective pull rod, and the locking device is used to lock the walking device.
[0014] The minimum distance limit varies for high-voltage lines with different voltages. Therefore, a walking device and a locking device are installed to adjust the distance between the protective barrier and the high-voltage pole, adapting to high-voltage poles of different voltage types.
[0015] Preferably, it further includes a fixing device for fixing the protective barrier in position on the protective rod.
[0016] The fixing device can be a pin, a buckle, or a spring clip. This fixing device prevents the protective barrier from sliding down the protective rod, thus ensuring the safety of the device.
[0017] Preferably, the fixing device includes pin holes and pin rods, and a plurality of pin holes are spaced apart along the length of the protective tie rod.
[0018] Multiple pin holes are spaced apart along the length of the protective tie rod to facilitate adjustment of the height of the protective barrier.
[0019] Preferably, the protective barrier comprises a first segment and a second segment that are perpendicular to each other, the first segment being perpendicular to the protective rod, and the second segment being fitted over the protective rod.
[0020] The protective barrier is L-shaped, and the second section is fitted with a protective tie rod, which provides more space to fix the protective barrier in place on the protective tie rod.
[0021] Preferably, the protective pull rod is provided with a reflective sheet on its exterior.
[0022] The protective rod is equipped with reflective strips on the outside, making it easier to spot at night and preventing accidental approach to high-voltage power poles.
[0023] Preferably, a warning light is provided on the outside of the protective pull rod.
[0024] If a warning light is installed on the outside of the protective rod, it will be easier to spot at night, preventing accidental approach to the high-voltage pole.
[0025] Preferably, it further includes a wind-resistant tie rod, with its two ends connected to the protective tie rod and the protective barrier, respectively.
[0026] By installing wind-resistant tie rods, the wind resistance of this device can be enhanced as much as possible, which helps to improve the structural stability of the device.
[0027] Preferably, the bottom of the protective rod is connected to a ground anchor.
[0028] Ground anchors are installed at the bottom of the protective tie rod to improve the structural stability of the device.
[0029] Preferably, the insulating protective component is a rubber sleeve.
[0030] Compared with existing technologies, the advantages of this utility model are as follows:
[0031] This utility model provides an isolation and protective frame for high-voltage electrical equipment, comprising a protective tie rod, a protective barrier, an insulating protective component, a monitoring device, and an alarm device. The protective tie rod is installed beside the high-voltage pole. The protective barrier is installed above the high-voltage pole, and its width is greater than the length of the crossarm, thus covering the high-voltage line fixed to the high-voltage crossarm. When debris falls from above the high-voltage pole, the protective barrier prevents the debris from contacting the high-voltage line, minimizing the possibility of short circuits or even fires caused by debris contacting the high-voltage line. The insulating protective component is fitted over the protective tie rod to ensure the safety of personnel and equipment. The monitoring device is equipped with an infrared distance sensor. When the monitoring device detects that the distance between an object and the high-voltage pole is less than a threshold, it sends a signal to the alarm device. The alarm device receives the signal and sounds an alarm, minimizing the possibility of tower cranes accidentally contacting the high-voltage line or personnel climbing over the protective barrier. This device overcomes the shortcomings of existing high-voltage isolation and protective frames, which cannot prevent debris falling from above the high-voltage pole from contacting the high-voltage line.

[0047] Protective barrier 2 is connected to the protective tie rod 1. The protective tie rod 1 is used to be installed above the high-voltage pole 6. The width of the protective barrier 2 is greater than the crossarm 601 of the high-voltage pole 6.
[0048] An insulating protective component, which is fitted over the protective pull rod 1;

The protective barrier 2 is installed above the high-voltage pole 6, and its width is greater than the length of the crossarm 601, thus covering the high-voltage line 602 fixed to the crossarm. When debris falls from above the high-voltage pole 6, the protective barrier 2 prevents the debris from contacting the high-voltage line 602, minimizing the possibility of short circuits or even fires caused by debris contacting the high-voltage line 602. An insulating protective sleeve is fitted over the protective tie rod 1 to ensure the safety of personnel and equipment. The monitoring device 4 is equipped with an infrared distance sensor. When the monitoring device 4 detects that the distance between an object and the high-voltage pole 6 is less than a threshold, it sends a signal to the alarm device 5.

[0052] Furthermore, such as Figure 4 and Figure 5 As shown, a walking device 201 and a locking device 202 are provided between the protective barrier 2 and the protective pole 1.

[0053] Furthermore, such as Figure 4 and Figure 5 As shown, it also includes a fixing device for fixing the protective barrier 2 to the position on the protective rod 1. In this embodiment, the fixing device includes pin holes 101 and pins 203, and a plurality of pin holes 101 are spaced apart along the length of the protective rod 1.
[0054] Furthermore, the protective barrier 2 comprises a first segment and a second segment that are perpendicular to each other. The first segment is perpendicular to the protective rod 1, and the second segment is fitted over the protective rod 1. The protective barrier 2 is L-shaped, and the second segment fitting over the protective rod 1 provides more space to fix the position of the protective barrier 2 on the protective rod 1.
[0055] Furthermore, a reflector 7 is provided on the exterior of the protective rod 1. And / or, a warning light 8 is provided on the exterior of the protective rod 1.
