Problems solved by technology

The protection effect of the existing cable grounding box on the grounding box body is not very obvious, especially in harsh conditions such as rainy and snowy days, exposure to the sun or dust, the outside or inside of the grounding box body will be corroded and aged, reducing the service life and damaging the internal circuit. The normal operation of the system poses a threat, which in turn affects the security and stability of the entire power system

Embodiment 1

[0036] Such as Figure 1 to Figure 10The dust-proof and moisture-proof cable grounding box shown includes a grounding box body 2, a protective window 1 and an alarm device 8. The grounding box body 2 is in the shape of a cuboid, and a box shed 3 is arranged above the grounding box body 2, and the box shed 3 is symmetrical. 'Eight' shape, the outer edge of both sides of the box shed 3 exceeds the upper horizontal surface of the grounding box body 2, which can prevent the corrosion of the cable grounding box body 2 by weather conditions such as rain and sun exposure, and increase the service life. The top of the box shed 3 is flat , the top of the box shed 3 is provided with 3 cable holes 31, the cable holes 31 are evenly distributed on the roof, and the inner diameter of the cable holes 31 matches the outer diameter of the cable, which can better seal. Box side 6 is arranged, and box side 6 upper part is provided with window 60, and window 60 is circular, and window 60 place is...

Embodiment 2

[0043] The use method of the dustproof and moistureproof cable grounding box of the present invention comprises the following steps:

[0044] First, the grounding cable is connected to the cable protection layer protection grounding box through the sealing tube 5 through the cable hole 31. The sealing tube 5 is cylindrical in shape, and its inner diameter matches the grounding cable. There are several layers of tube umbrellas 51 on the outside of the sealing tube 5. , the lower end of the tube umbrella 51 is provided with a tube pad 52, and the sealing tube 5 at the lower end of the tube pad 52 is directly inserted into the cable hole 31 along with the grounding cable to improve the waterproof sealing effect;

[0045] Second, the threshold value of temperature, humidity and smoke is set by the alarm device 8 setting module 802. When the temperature sensing device 803, the humidity sensing device 804, and the smoke monitoring device 805 sense that the temperature in the groundin...

Embodiment 3

[0049] The use method of the dustproof and moistureproof cable grounding box of the present invention comprises the following steps:

[0050] First, the grounding cable is connected to the cable cross-connection protection grounding box through the sealing tube 5 through the cable hole 31. The sealing tube 5 is cylindrical in shape, and its inner diameter matches the grounding cable. There are several layers of tube umbrellas 51 on the outside of the sealing tube 5. , the lower end of the tube umbrella 51 is provided with a tube pad 52, and the sealing tube 5 at the lower end of the tube pad 52 is directly inserted into the cable hole 31 along with the grounding cable to improve the waterproof sealing effect;

[0051] Second, the threshold value of temperature, humidity and smoke is set by the alarm device 8 setting module 802. When the temperature sensing device 803, the humidity sensing device 804, and the smoke monitoring device 805 sense that the temperature in the groundin...

Abstract

The invention relates to a dustproof moisture-proof cable grounding box, which relates to the technical field of cable grounding boxes. The dustproof moisture-proof cable grounding box comprises a grounding box body, a protection window and an alarming apparatus, and is characterized in that a box shed is arranged above the grounding box body, the top of the box shed is provided with a plurality of cable holes, two sides of the grounding box body are respectively provided with a box edge, the middle-upper part of the box edge is provided with a window opening, the window opening is provided with a protection window, a plurality of baffle plates are arranged inside the protection window, and the alarming apparatus is arranged inside the grounding box body. By adopting the detachable protection window, the rainy water and dust can be effectively prevented from entering the grounding box body, the protection window is convenient to clean, and the service life of the grounding box can be prolonged; and the alarming apparatus is arranged inside the grounding box body, so that when the temperature, humidity or dust inside the grounding box body is greater than a threshold value, a dangerous signal is transmitted to the maintenance personnel; and the dustproof moisture-proof cable grounding box is safe, easy to install, capable of saving the space, and capable of improving the safetyand stable operation capability of a power system.

Description

Technical field: [0001] The invention relates to the technical field of cable grounding boxes, in particular to a dust-proof and moisture-proof cable grounding box and a use method thereof. Background technique: [0002] The high-voltage conductors are isolated by solid insulating materials and enclosed in metal shielding tubes, so that the cables can achieve safer and more reliable power transmission. The metal shielding tube of the cable must be effectively and reliably grounded to ensure the long-term and stable function of the cable insulation. The 35kV large-section power cables currently used in my country and the power cables with voltage levels of 66kV, 110kV and above are all single-core cables. One end of the cable metal sheath is connected to the ground and the other end is not grounded. When the wave or internal passing voltage flows along the cable core, the phenomenon that the cable metal sheath is not grounded will cause a high impulse overvoltage phenomenon, ...
