Description

Technical Field

[0001] This utility model belongs to the field of grounding devices and relates to a safety grounding device for a power distribution cabinet. Background Technology

[0002] In modern power systems, distribution cabinets serve as the core hub for power distribution and control, and the reliability of their safety grounding devices directly affects the stable operation of the power system and the safety of personnel. Grounding devices not only need to quickly conduct fault currents to reduce the risk of electric shock when equipment leaks current, but also need to promptly discharge instantaneous large currents in the event of lightning strikes or operational overvoltages to protect equipment from damage.

[0003] During the operation of the safety grounding device of the distribution cabinet, the outlet is a key part connecting the grounding wire to the external grounding grid. Its protective performance directly affects the reliability and safety of the grounding system. The outlet not only undertakes the function of transmitting large currents such as fault current and lightning current, but also needs to resist the erosion of the external environment for a long time to avoid grounding failure due to cable wear, moisture short circuit or foreign object intrusion.

[0013] This utility model provides a safety grounding device for a power distribution cabinet, which has the following advantages: 1. This type of power distribution cabinet safety grounding device, through the setting of a protective mechanism, when the device is to be used, the external power distribution box is suspended in the air by an external support column. The grounding wire extends from the inside of the power distribution box to the outside and connects to the ground. However, the outlet of the grounding wire from the power distribution box is susceptible to corrosion. Therefore, a sealing box is installed on the outside of the outlet to protect the outlet. A protective tube is set on the right side of the sealing box. The grounding wire passes through the inside of the protective tube and enters the mounting box. A cable tray is installed inside the mounting box. Many sliding rods are installed on the surface of the cable tray. Sliding retaining rings are installed on both sides of the sliding rods. The retaining rings clamp the grounding wires in an orderly manner from both sides and are fixed with fixing bolts to maintain the orderly arrangement of the grounding wires. Then, the grounding wire connects to the ground from the outlet at the bottom of the sealing box and the connecting protective tube outside the outlet. This plays a role in protecting the grounding wire, increasing its service life and orderliness, and avoiding damage caused by external conditions, such as cable wear, moisture short circuit, or even grounding failure.

[0014] 2. This type of power distribution cabinet safety grounding device, through the setting of the installation mechanism, has connecting blocks installed on the left and right sides of the installation box when the device is to be used. Metal straps are connected to the outside of the connecting blocks. The metal straps install the sealed box with the grounding wires arranged on the external support column, so that the grounding wires can be tied to the support column and arranged in an orderly manner to the ground. Because there are many adjustment holes on the surface of the metal straps, the adjustment buckles are inserted into the adjustment holes, which can be installed and fixed according to the thickness of the external support column. This plays a role in ensuring that the grounding wires are connected to the ground in an orderly and firm manner. It avoids the grounding wires being affected by bad weather due to poor fixation, which would reduce the conductivity and reduce the safety of electricity use. Attached Figure Description
