Research on the condition evaluation system of the main electric circuit electrical connection equipment of catenary

It is difficult to find the temperature abnormity of the main electric circuit electrical connection equipment of the catenary. Once the temperature abnormity of the electrical connection equipment is caused, it will seriously affect the safe operation of the catenary. Therefore, a state evaluation system based on temperature monitoring technology and background management development technology is developed to monitor the temperature of the electrical connection equipment of the main electric circuit, and the collected temperature data is transmitted to the background system through wireless communication.The background system judges whether the equipment is in normal operation state, so as to discover the heating defects of the electrical connection equipment timely and effectively, At the same time, it is of great significance to ensure the safe and reliable operation of the catenary, to effectively monitor and evaluate the temperature of the electrical connection equipment of the main electric circuit.
