Electric equipment control circuit applied to supersonic combustion test

Abstract

The invention discloses an electric equipment control circuit applied to supersonic combustion test. The electric equipment comprises a power supply and control button power supply module, an emergency stop circuit module, a pure manual button circuit module, a manual button circuit module, a pure manual circuit module, a manual-automatic integrated circuit module and an automatic control module. The electric equipment control circuit can be used for manually and automatically controlling various types of equipment applied to the supersonic combustion test, wherein a manual control function is suitable for debugging in a non-experimental process, and an automatic control function can be used for accurately controlling the time sequences of all types of equipment applied to an experiment, so that the supersonic combustion test can be conducted orderly and normally. In case of various emergency situations in the experimental process, the control circuit can be used for switching off dangerous equipment through an emergency stop button, so that experimental safety is ensured. If a main power supply is damaged due to the situations of short circuit and the like in an experimental process, the control circuit can be used for rapidly switching to a standby power supply to supply power to the equipment continuously, so that experiments can be conducted safely.

Description

technical field [0001] The invention relates to the field of supersonic combustion tests, in particular to an electrical equipment control circuit applied to supersonic combustion tests. Background technique [0002] In the supersonic combustion test, various gases and liquids (mainly air, hydrogen, oxygen, nitrogen, ethylene, aviation kerosene, etc.) need to be transported through pipelines with a certain flow ratio and accurate arrival time in the combustion chamber to complete the ignition, combustion and The process of doing work. In the experiment, hydrogen and oxygen are usually ignited at the first confluence to produce a high temperature (temperature greater than 1200 degrees Celsius), high pressure (pressure higher than 1MPa) gas, and this high temperature, high pressure gas passes through a Laval nozzle to generate supersonic flow (Mach The number is greater than 2), and then the supersonic airflow enters the combustion chamber, injects kerosene into the combustio...

AI Technical Summary

Problems solved by technology

[0003] In the existing supersonic combustion test, the control circuit of the test bench is relatively simple. During the experiment, if dangerous measures such as flammable gas leakage occur, the emergency handling capability of the control system is weak; the reliability of the power supply is poor. If some electrical short circuits occur, The damage to the power supply is relatively large, which makes the control system malfunction and is prone to danger
