Description

Technical Field

[0001] The utility model belongs to the technical field of electromechanical engineering, and particularly relates to a control cabinet for electromechanical engineering. Background Art

[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical equipment and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system.

[0003] A Chinese patent application with publication number CN215989863U discloses a control cabinet for electromechanical engineering, including a base plate, a universal wheel fixedly connected to the bottom of the base plate, a buffer device fixedly connected to the top of the base plate, the base plate fixedly connected to a fixed frame through the buffer device, a lifting device fixedly connected to the top of the fixed frame, and a cooling fan fixedly connected to one end of the lifting device located inside the fixed frame. The utility model relates to the technical field of electromechanical engineering. The control cabinet for electromechanical engineering achieves the goal of being easy to move as a whole. The base plate supports the fixed frame through the buffer device, so that the fixed frame has a certain buffering performance, improves the protection of the fixed frame, reduces the damage to the electrical components in the fixed frame, and increases the service life of the equipment. A lifting device is arranged above the fixed frame to facilitate the up and down movement of the cooling fan in the fixed frame, thereby improving the heat dissipation efficiency inside the fixed frame, thereby increasing the service life of the equipment and meeting the purpose of use requirements.

[0004] Although the control cabinet can be protected by the buffer device and the matching cooling fan to improve its buffering effect and heat dissipation performance, it does not have an automatic fire extinguishing function. When an open fire occurs inside the control cabinet due to aging of the circuit, it cannot be handled in time, which is likely to cause greater economic losses and is highly dangerous. For this reason, we provide a control cabinet for electromechanical engineering to solve the above problems. Utility Model Content
