Circuit compatible with various switch machine actions and control method

Abstract

The invention relates to a circuit compatible with various switch machine actions and a control method. The circuit is characterized by comprising an alternating current switch machine circuit, a direct current switch machine circuit and a quick switch machine circuit, the control circuit is formed by electrically connecting contacts of a 1DQJ starting relay, a 1DQJK quick-action starting relay, a 2DQJ starting relay, a 1DQJF starting repeating relay, a DRCQ, a DCCQ alternating current contactor, a KDCQ alternating current contactor and a relay, the control circuit is connected with each test loop and performs action control on various switch machines, the control circuit receives a command from the DCJ or the FCJ and is connected with a power supply, and the control circuit is connected with the relay. And the functions of excitation, stage switching, self-protection, disconnection, slow release and the like of related relays and contactors are realized. The device can test both alternating current and direct current. Both quick movement and slow movement can be tested; the purpose of testing different switch machines on one test bench is achieved, the equipment is simplified, the cost is reduced, the efficiency is improved, and the field requirements are met.

Description

technical field [0001] The invention belongs to the technical field of railway signal control, and in particular relates to a circuit and a control method compatible with the actions of various switch machines. Background technique [0002] With the development of railway signaling technology and equipment, the switch machines for railway turnouts have changed from four-wire system to five-wire system, from DC to AC, from electric to hydraulic. The switch machine operation line of the railway signal repair station for the machine maintenance and test work has brought difficulties. Different switch machines should be tested on different test benches; several test benches should be placed in one area; the test methods of each machine are various. Consistent, not only affects the efficiency, but also adverse to management; for example, for the DC drive switch machine, only the DC switch machine test equipment can be used for testing, and for the AC drive switch machine, only th...

Problems solved by technology

[0002] With the development of railway signal technology and equipment, the switch machines for railway turnouts have changed from four-wire system to five-wire system, from DC to AC, from electric to hydraulic, and the models and standards are also increasing. The switch machine operation line of the railway signal repair station for machine maintenance and testing has brought difficulties. Different switch machines have to be tested on different test benches; several test benches have to be placed in one area; the test methods for each station are different. Consistent, which not only affects the efficiency, but also is unfavorable to management; for example, for DC drive switch machines, only DC switch machine test equipment can be used for testing, and for AC drive switch machines, only AC switch machine test equipment can be used for testing, etc.
