Abstract

The invention relates to an electronic simulation device for a five-wire system alternating current point switch. The device is connected with a point switch control circuit and used for simulating positioning drive, positioning representing, anti-position drive and anti-position representing functions of the point switch, and can give corresponding state indicator lamps. The simulation device comprises an interface connecting line, a resistor for simulating impedance of a three-phase motor winding inside the point switch, a diode Z1 for forming a representing loop, two relays for simulating ashutter inside the point switch, four LED indicator lamps which are the positioning drive indicator lamp, the anti-position drive indicator lamp, the anti-position representing indicator lamp and thepositioning representing indicator lamp, and four current transformers connected in the main loop in series preliminarily for sensing loop current and secondarily generating a control circuit. Compared with the prior art, the device has the advantages of being small in size, low in weight, convenient to install and arrange.

Description

technical field [0001] The invention relates to the field of rail traffic signals, in particular to an electronic simulation device for a five-wire AC switch machine. Background technique [0002] In the field of railway and rail traffic signals, the model of the five-wire AC switch machine is ZDJ9, S700K-C, which has many disadvantages for the early interlocking system interface debugging or scientific research and teaching in railway colleges: [0003] 1. The actual installation area of ​​a single switch machine is at least 1m2, and the weight is about 100kg, which is inconvenient to install. [0004] 2. The noise of the actual switch machine is too large when it is rotating, and the moment when the action rod of the switch machine expands and contracts is relatively large during rotation, which poses a hidden danger to personal safety. [0005] 3. It takes a long time for the actual switch machine to turn in place, usually about 6s. [0006] 4. The actual switch machine...
