Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving high and low voltage distribution cabinets, and more specifically, to an energy-saving high and low voltage distribution cabinet with relay protection. Background Art

[0002] Energy-saving high and low voltage distribution cabinet is a kind of distribution equipment used in power system, which is mainly used for distribution, control, protection and monitoring of electric energy. It usually consists of high voltage and low voltage parts, which are used to realize power distribution and management of power system. However, the existing distribution cabinet is not energy-saving and environmentally friendly, and its internal heat dissipation effect is poor, and it cannot quickly complete the heat dissipation effect, which reduces the efficiency and effect of the use of the distribution cabinet.

[0003] After searching, the Chinese patent with announcement number CN216390239U discloses an energy-saving high and low voltage distribution cabinet. The energy-saving high and low voltage distribution cabinet allows external air to flow into the interior of the heat conduction plate through the heat dissipation grille, so that the internal air can circulate and perform necessary heat dissipation on the equipment. The bottom air enters through the air inlet pipe, the filter plate filters impurities, and the cold air quickly enters the top space of the installation plate through the guide block, completing the heat dissipation effect of the electronic equipment. The hot air is discharged through the ventilation fan, thereby forming a relatively circulating environment inside and ensuring the heat dissipation effect.

[0004] When the above energy-saving high and low voltage distribution cabinet is in use, external air is introduced into the cabinet through the heat dissipation grille, and the electrical equipment in the cabinet is cooled. However, when used in the rainy season, moisture in the external environment will also enter the cabinet through the heat dissipation grille. The moisture will cause the electrical equipment in the cabinet to get damp and affect the normal operation of the electrical equipment. Utility Model Content

[0009] Furthermore, a threaded piston is movably provided on one side of the hair dryer, and the threaded piston is threadedly connected to the main body of the energy-saving high and low voltage distribution cabinet.

[0010] It can be seen that in the above technical solution, the threaded piston is rotated and moved away from the main body of the energy-saving high and low voltage distribution cabinet, and then new coolant is added into the bottom frame.

[0011] Furthermore, a mesh plate is movably provided on the top of the hair dryer, and the mesh plate is fixedly installed inside the main body of the energy-saving high and low voltage distribution cabinet.

[0012] It can be seen that in the above technical solution, the mesh plate separates the electrical equipment and the hair dryer.

[0016] It can be seen that in the above technical solution, before installation, two sliders are placed on both sides of the connection block, and four plug boards are inserted into the connection block, and multiple wirings are separated by multiple partitions to prevent multiple wirings from being entangled with each other.
