Switch cabinet with stable fireproof performance

Abstract

The invention relates to the technical field of switch cabinets, in particular to a switch cabinet with stable fireproof performance, and the switch cabinet comprises a switch cabinet main body, a protective layer is fixedly connected to the inner wall of the switch cabinet main body, a fixed frame is fixedly connected to the inner wall of the left side of the switch cabinet main body, and a screw rod is inserted into the fixed frame, the surface of the screw rod is fixedly connected with a twisting handle, and the surface of the end, penetrating through the inner wall of the fixed frame, of the screw rod is sleeved with a bearing seat. According to the invention, a limiting block is arranged, and the screw rod is rotated to drive a moving block to abut against a T-shaped rod to slide in a stabilizing rod, so that the wiring harness can be independently limited, and the situation that a whole bus is on fire due to the fact that individual wiring harness is heated is avoided, a fireproof adhesive tape is disposed on the inner wall of the limiting block, when individual wiring harness is overheated and is on fire, the fireproof isolation effect on the wire harnesses in the switch cabinet main body can be effectively achieved, meanwhile, the connecting wire harnesses in the switch cabinet main body can be combed, and the maintenance efficiency of maintenance personnel on the wire harnesses is improved.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a switch cabinet with stable fireproof performance. Background technique [0002] The main function of the switchgear is to open and close, control and protect the electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switchgear mainly include circuit breakers, insulating parts, operating mechanisms, Transformers and various protection devices. [0003] The sealing performance of the existing switchgear is poor. When a fire occurs, it is easy to cause the electrical equipment inside the switchgear to burn together, causing more serious losses. Moreover, due to the complexity of the internal connection lines of the switchgear, when individual lines are overheated and not detected in time , the entire busbar will be affected, leading to a serious fire in the switchgear, and th...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a switchgear with stable fireproof performance to solve the poor sealing performance of the existing switchgear proposed in the above background technology. More serious losses, and because the internal connection lines of the switchgear are complicated, when individual lines are overheated and not detected in time, the entire busbar will be affected, resulting in a serious fire in the switchgear, which has certain safety hazards, and the existing switchgear There are many lines inside the cabinet. If the wiring harness is not sorted out, it will increase the workload of the maintenance personnel, reduce the maintenance efficiency, and reduce the use space of the switch cabinet, which will have a certain impact on the actual use.
