Description

Technical Field

[0001] The utility model relates to the technical field of power distribution protectors, in particular to a high and low voltage power distribution integrated protector. Background Art

[0002] When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other devices in the circuit. Surge protectors are suitable for AC 50 / 60HZ, rated voltage 220V to 380V power supply systems, and protect against indirect lightning and direct lightning effects or other transient overvoltage surges. When existing surge protectors are installed in distribution boxes, they are usually fixed in the distribution box using multiple screws, which is troublesome to install and remove and is easy to damage the surge protector shell.

[0003] The patent with authorization announcement number CN210224599U discloses a high and low voltage transformer and distribution integrated protector for building construction. By providing a fixing mechanism, it is not only convenient for the installation and disassembly of the protector body, saving time and effort, but also can be adjusted according to the size of the protector body. However, in this utility model, the protector body is directly exposed and installed in the distribution box, and no external protective shell and branch line fixing mechanism are provided. When the protector body is connected, the wiring cannot be distinguished and fixed, resulting in messy placement of the wiring. When the protector body is protected by an external shell, it will cause inconvenient maintenance. Utility Model Content
