Description

Technical Field

[0001] The utility model relates to the technical field of power supply lightning arresters, in particular to a power supply lightning arrester with a communication function. Background Art

[0002] Power lightning arrester is also known as lightning arrester, surge protector, and surge protector. In the information age, computer networks and communication equipment are becoming more and more sophisticated, and the requirements for their working environment are becoming higher and higher. Lightning and instantaneous overvoltage of large electrical equipment will more and more frequently invade indoor electrical equipment and network equipment through power supplies, antennas, radio signal transceiver equipment and other lines, causing damage to equipment or components, casualties, interference or loss of transmitted or stored data, and even causing electronic equipment to malfunction or temporarily paralyzed, system pauses, data transmission interruptions, local area networks and even wide area networks to be damaged. The hazards are shocking, and indirect losses are generally far greater than direct economic losses. Power lightning arrester is a device that uses modern electricity and other technologies to prevent being struck by lightning.

[0003] For example, a Chinese patent (publication number: CN 219351255 U) discloses a power supply lightning arrester, including a mounting seat and a lightning arrester, one side of the mounting seat is configured with a mounting groove, the top of one side of the mounting seat is configured with multiple groups of input terminals, the bottom of one side of the mounting seat is configured with multiple groups of output terminals, the top and bottom walls of the mounting groove in the mounting seat are respectively configured with multiple groups of slide grooves, the top and bottom of the lightning arrester are respectively fixed with multiple groups of bayonet plates slidably connected to the multiple groups of slide grooves, the top and bottom of the mounting groove in the mounting seat are respectively installed with connecting grooves, and one side of the lightning arrester is fixed with two groups of bayonet plates, and the bayonet is more stable when moving by providing a slide plate and a slide rail, and when the two groups of bayonet pins are away from each other, they enter the bayonet plate for buckle fixation, and the driving gear and rack are provided to facilitate the transmission of energy to the bayonet pin and then buckle fixation with the bayonet plate. This method can not only fix the main body of the lightning arrester and achieve the purpose of high installation stability, but also is relatively stable and convenient to operate, and is convenient for installation and disassembly of the lightning arrester.

[0004] The above-mentioned power supply lightning arrester still has certain shortcomings. When the lightning arrester is completely in contact with the inner wall of the mounting groove in the mounting base, the driving gear is driven to rotate by turning the knob, and the driving gear is engaged with the two sets of racks to drive the two sets of pins to move away from each other. The slide plate and the slide rail are provided to make the pins more stable when moving. However, the power supply lightning arrester lacks communication function, and it is impossible to detect abnormal grounding through the lightning arrester. The function appears "flashing" and emits a "beeping" sound, and the grounding resistance cannot be measured through the grounding body, so that the grounding resistance is displayed in the function area for real-time monitoring in the background. Therefore, a power supply lightning arrester with communication function is proposed to solve the above problems. Utility Model Content

When the movable block 505 moves, it drives the T-shaped block to slide inside the T-shaped slot, thereby increasing the stability of the movable block 505 when moving. When the movable block 505 moves, it drives the second clamping rod 506 to move together. At this time, insert the limit block 509 into the limit slot 507, release the pull rod 503, and the movable block 505 will reset under the action of the spring 504, driving the second clamping rod 506 to clamp into the second clamping hole 508, so as to install the lightning arrester body 2.
