Description

Technical Field

[0001] The utility model relates to the technical field of secondary protection devices for power transmission and transformation facilities, and particularly relates to a secondary protection device for power transmission and transformation facilities which is convenient for installation. Background Art

[0002] Secondary protection devices for power transmission and transformation facilities are important components in the power system. They are usually installed in substations to monitor, control, and protect the current, voltage, etc. of the power system. These devices include, but are not limited to, relay protection devices, measuring instruments, control equipment, etc. They work together to ensure the stable and safe operation of the power system.

[0003] Compare the published patent No. CN 216435579 U, a secondary protection device for power transmission and transformation facilities which is convenient for installation, including a protection shell. There are two protection shells symmetrically arranged. One side of the protection shell is rotatably connected with a first heat dissipation baffle through a hinge, and the other side of the protection shell is rotatably connected with a second heat dissipation baffle through a hinge. Heat dissipation slots are opened on one side of the first heat dissipation baffle and the second heat dissipation baffle, and there are several heat dissipation slots. Supporting ears are arranged on the same side of the protection shell and the second heat dissipation baffle. A support plate is arranged on the side of the protection shell close to the first heat dissipation baffle. Cross bars are arranged at the top of the protection shell, and the middle of the cross bars is fixedly connected through adjusting bolts. Preferably, waist-shaped holes are opened on one side of the supporting ears and the support plate, and a round hole is opened on one side of the first heat dissipation baffle. Preferably, clamping groove plates are fixedly connected to both sides of the protection shell, and a reinforcing member is slidably connected inside the clamping groove plate. The reinforcing member is in an inverted C shape. Supporting ears are arranged on the same side of the second heat dissipation baffle and the protection shell, and the same waist-shaped hole is opened on one side of the supporting ears. The installation bolt passes through the inside of the waist-shaped hole to fix the second heat dissipation baffle and the protection shell. Support plates are arranged at the top and bottom inside the protection shell, and the support plates fix the protection shell and the first heat dissipation baffle through installation bolts, so as to achieve the protection effect.

[0004] For the secondary protection device for power transmission and transformation facilities which is convenient for installation, the second heat dissipation baffle and the protection shell are fixed. Support plates are arranged at the top and bottom inside the protection shell, and the support plates fix the protection shell and the first heat dissipation baffle through installation bolts, so as to achieve the protection effect. However, the heat dissipation baffle is not convenient for dissipating heat according to the usage situation of the power transmission and transformation facilities inside the protection shell. When the equipment does not need heat dissipation, the slots opened on the heat dissipation baffle accumulate dust for a long time, affecting the normal heat dissipation and air circulation of the equipment.
