Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to neutral current eliminators. Background Technology

[0002] A neutral current eliminator is a device used to eliminate neutral current generated in a power system due to unbalanced loads or equipment failures. By detecting and processing abnormal neutral current, it protects electrical equipment from the effects of current fluctuations and ensures the safe and stable operation of the system. This device is commonly used in industrial and commercial power systems and can effectively reduce the failure rate of electrical equipment and improve the reliability and safety of the electrical system.

[0003] Currently, the relevant neutral current eliminators lack shielding and bottom heat dissipation structures. When installed in locations susceptible to external electromagnetic interference, they are easily affected by interference, impacting the stable operation of the device. Furthermore, the lack of bottom heat dissipation limits the installation conditions. When installed in locations where other equipment is installed close to both sides, heat dissipation may be insufficient, affecting the normal operation of the device. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a neutral current eliminator.

[0005] The neutral current eliminator provided in this application adopts the following technical solution:

[0006] A neutral current eliminator includes an eliminator body, a tray, and a fan assembly. The bottom of the eliminator body has a heat dissipation groove, and an aluminum foil layer surrounds the eliminator body. A limiting block is fixedly connected to the bottom of the eliminator body, and a tray is movably mounted on the bottom of the limiting block. A fixing plate is fixedly connected to the top of the tray, and the limiting block and the fixing plate are fitted together. A threaded rod is movably mounted between the fixing plate and the limiting block. A shock-absorbing plate is fixedly connected between the fixing plate and the tray. A fan assembly is fixedly connected inside the tray, and a grounding groove is provided inside the tray on one side of the fan assembly. A grounding rod is installed inside the grounding groove and fixedly connected to the eliminator body.

[0007] Preferably, the limiting block has a bolt hole inside, and the threaded rod is threadedly connected to the bolt hole.

[0008] Preferably, positioning elements are fixedly connected to both sides of the tray, and the positioning elements have fixing holes inside.

[0009] Preferably, positioning blocks are fixedly connected to the bottom of the eliminator body on both sides of the limiting block, and the positioning blocks are fitted into the fixing plate.

[0010] Preferably, the threaded rod passes through the fixing plate and the limiting block.

[0011] To sum up, the application includes the following beneficial technical effects:

[0012] Through the electromagnetic shielding function of the aluminum foil layer, external electromagnetic interference is effectively reduced, ensuring the stability of the internal circuit of the equipment. Through the rubber material of the shock-absorbing plate, vibration force is absorbed and slowed down, enhancing the equipment's resistance to external vibration and improving the stability and durability of the equipment. Through the synergistic effect of the heat sink and the fan group, heat is quickly discharged, and the bottom heat dissipation design effectively reduces the restriction on the installation environment, so that the equipment can maintain good heat dissipation effect even when installed close to external equipment. Through good contact between the grounding rod and the ground, electrical safety is improved, preventing current leakage and safety accidents. Through the quick disassembly design of the tray, the maintenance and replacement of the equipment are facilitated, further improving the convenience and safety during use.
