Description

Technical Field

[0001] The utility model relates to a cooling device for an electrical engineering relay protector, belonging to the technical field of relay protectors. Background Art

[0002] Relay protection in electrical engineering is an important device, mainly used for fault detection and electrical equipment protection in power systems. It can monitor circuit parameters and signals, and quickly cut off the circuit when a fault or abnormal situation occurs in the power system to protect the safety of electrical equipment and personnel. Relay protection is usually composed of induction elements, relays and trigger devices, etc., and can detect faults based on parameters such as current, voltage, frequency and phase. When these parameters exceed the set value, the relay will be triggered, and then send a signal to the protection device to cut off the fault circuit. For example, when the current exceeds the set value, the relay will operate to cut off the fault circuit; when the voltage is too high or too low, the relay will also operate to avoid damage to electrical equipment; when the frequency deviates from the normal range, the relay will also operate to prevent frequency faults in the power system.

[0003] However, when the relay protector is working, heat is generated, so the relay protector needs to be cooled and cooled. Fan cooling is a common heat dissipation method, but the fan is generally fixed during installation, so the fan can only dissipate heat at one point, making the heat dissipation effect of other parts poor. In addition, the existing relay protector is generally installed by bolts, which is relatively inconvenient to install and disassemble.

[0004] In view of this, a cooling device for an electrical engineering relay protector is proposed. Utility Model Content

[0010] Furthermore, in order to make the rotating ring rotate on the mounting plate, the rotating cooling assembly includes mounting plates fixedly mounted on both ends of the outer side walls of the relay protector body, and a circular rotating ring is rotatably mounted on the mounting plate.

[0011] Furthermore, in order to enable the circular rotating ring to drive the cooling fan to rotate synchronously, the cooling fan is fixedly mounted on the outer wall of the circular rotating ring, and a gear ring is fixedly connected to the outer wall of the circular rotating ring.

[0026] The rotating cooling component 9 includes a mounting plate 901 fixedly mounted on both ends of the outer wall of the relay protector body 7, a circular rotating ring 902 is rotatably mounted on the mounting plate 901, a cooling fan 903 is fixedly mounted on the outer wall of the circular rotating ring 902, a gear ring 904 is fixedly connected to the outer wall of the circular rotating ring 902, a support frame 905 is fixedly connected to the outer wall of the relay protector body 7, a drive motor 906 is fixedly connected to the top of the support frame 905, a drive gear 907 is connected to the output shaft of the drive motor 906, the drive gear 907 is meshed with the gear ring 904, the drive motor 906 can drive the drive gear 907 to rotate, thereby rotating the gear ring 904 and the circular rotating ring 902, and the drive motor 906 is a forward and reverse motor.

[0027] When the utility model is in use, before using the relay protector body 7, the user can first install the connecting base 1. After the connecting base 1 is fixed, the user can place the T-shaped base plate 3 into the T-shaped slot on one side of the mounting plate 2. Before the T-shaped base plate 3 is placed in the T-shaped slot, the user needs to shrink the limiting plug plate 506 in the side mounting slot on the circular top plate 504. When the limiting plug plate 506 shrinks, the spring 505 can be squeezed.

At this time, the T-shaped base plate 3 and the relay protector body 7 can be fixed. Since there are multiple limiting plug plates 506, when the spring 505 on a limiting plug plate 506 is damaged, the user can first fix the fixing screw 50 3, and then the user can make the circular drum 502 drive the circular top plate 504 to rotate.

When the relay protector body 7 is working, the user can first make the cooling fan 903 work, and then the user can make the driving motor 906 work and drive the driving gear 907 to rotate, so that the gear ring 904 and the circular rotating ring 902 can be rotated, and then the circular rotating ring 902 can drive the cooling fan 903 to rotate. When the cooling fan 903 rotates, it can rotate the inside of the relay protector body 7 through the ventilation hole 8 to evenly dissipate heat, thereby reducing potential problems caused by local overheating. The uniform heat dissipation also helps to improve the overall performance and life of the relay protector body 7, thereby improving the reliability of the entire power system.
