Factors Affecting Railway Traffic Safety ?
1. Equipment defects and failure factors
From the perspective of fundamental factors, the safety and quality of Silver Contact Brazed CNC Copper for Train Electrical Switch equipment is the basis for determining the safety of railway traffic. If there are defects and failures in Silver Contacts Brazing with Copper CNC Parts equipment, it will inevitably induce traffic safety accidents. Looking at past cases, it is not difficult to see that some accidents were caused by failures of locomotive Silver Sheet Welded with Copper CNC equipment, such as brake system failures, signal lamp failures, and short-circuits of wires. These failures will affect the safety of railway traffic.
2. Human error
The impact of the staff's professional quality on railway traffic safety cannot be ignored. If the driver's driving skills are not skilled enough and the safety awareness is low, it will inevitably pose a threat to traffic safety. Secondly, the professionalism and safety responsibility awareness of the staff who maintain or repair the railway do not meet the standard requirements, which will also affect driving safety.
3. External environmental factors
External environmental factors, especially natural disasters such as strong winds, rainstorms, blizzards, sandstorms, earthquakes, mudslides, and landslides, will seriously affect the safety and quality of railway transportation.
The railway signal relay is a special electromagnetic switch device in various railway signal equipment or systems
Railway signal relays which made of Silver Tip Brazing Copper CNC refer to special electromagnetic switching devices in various types of railway signal equipment or systems. It consists of electromagnetic coil, contact group, transmission system and components to ensure that the Silver Contact Welding are closed or opened. The main types are: DC non-polar relays, polarized relays, polarity maintaining relays, etc. Taking the DC stepless relay as an example, when the calibrated working current is applied to the coil, the electromagnet drives the contact system to make the front Welded Electrical Contact and the middle Welding Electrical Contact close, and the coil is powered off or the current drops below the specified value. The gravity of the heavy hammer disconnects the middle contact from the front contact and closes the rear contact. The purpose of adding weight to the hammer is to ensure that the Railway Relay Contacts are reliably closed or disconnected structurally. The gravity or spring-gravity relays used by railway signals in circuits requiring fault-oriented safety performance are called railway signal safety relays. The DC non-polar relay has only two states: the front Electrical Contacts Machining Assemblies is closed or the rear contact is closed; the bias relay is closed when the forward current is applied. When there is no electricity or a reverse current is passed, the relay does not act, and it has the function of reflecting the polarity of the current; when the polarity maintaining relay is passed with a forward or reverse current, the relay contact system is in one of the two states respectively. State, the forward suction contact is closed or the negative drop contact is closed. When the coil is de-energized, the Resistance Brazing Electrical Contacts system remains in the state before the de-energization.
The reliability and safety of railway signal relays with Welded Contacts in use are necessary requirements to ensure the normal operation of various automatic control and remote control signal equipment. Therefore, the railway puts forward strict requirements on the signal relay; the contact system must act consistently, reliably and accurately; it has a long service life; Excellent electrical insulation strength; stable time characteristics and electrical parameter characteristics.
