A kind of automatic fire extinguishing system inside motor compartment of subway mcc system and its control method

Abstract

The invention belongs to the technical field of a subway MCC system, and in particular relates to an automatic fire extinguishing system inside a motor compartment of a subway MCC system, comprising a fire extinguishing inspection component, a fire extinguishing component, a control component and a material distribution component. The fire extinguishing inspection component includes an installation frame, a first A guide frame, a second guide frame and a toothed belt are fixedly connected to the top of the mounting frame, and a driving gear is connected to the output end of the motor. The driving gear is driven by the motor to rotate, and the action of the four sets of limit gears guides the toothed belt. When the driving gear rotates, it drives the toothed belt to drive synchronously, and at the same time, it meshes and drives the driven gear. A guide pin follows and slides in the first guide groove, and the second guide pin follows and slides in the second guide groove, so as to detect the cyclic movement of the housing on the inner wall of the installation frame, and dynamically detect the effect of the interior of the machine room in real time.

Description

technical field [0001] The invention belongs to the technical field of a subway MCC system, in particular to an automatic fire extinguishing system inside a motor compartment of the subway MCC system and a control method thereof. Background technique [0002] The motor control center (MCC) can realize the start and stop control of the motor and simple fault detection. It has reliable performance and is convenient for maintenance. It is widely used in various fields of the national economy, especially petrochemical, metallurgy, papermaking, building materials, textiles, and food processing. , pharmaceutical, power and other fields that require process control. [0003] At present, in the process of subway construction, it is necessary to install the MCC system. The primary circuit of the MCC system consists of circuit breakers, contactors, motor protectors and motors. The components used to install the MCC system work in a high-load environment for a long time, which is easy ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of subway construction, it is necessary to install the MCC system. The primary circuit of the MCC system is composed of circuit breakers, contactors, motor protectors and motors. As the temperature rises, local fires will occur, and there are certain safety hazards. Therefore, in order to solve the above problems, there is a need for an automatic fire extinguishing system inside the motor compartment of the subway MCC system and its control method
