MR081E Advanced Rail Control Circuit Training Console Educational Lab Equipment Instructional Package Electrical Skills Training I.Product Overview 1.1 Overview This product uses AX series safety relays for optimized design. According to the characteristics of Siemens S700K switch machine, it realizes the construction of S700K speed-up track circuit training. It is practical, flexible in application, and highly reliable. It is the preferred electrical equipment for rail transit professional training. With the rapid development of electrified railways and urban rail transit in my country, in order to meet the needs of speed increase, the S700K AC speed-regulating switch machine introduced equipment and technology from Siemens in Germany, and the digested and improved S700K AC speed-regulating switch machine quickly replaced the early ZD6 DC speed-regulating switch machine. The S700K switch machine is used on major domestic lines. The S700K electric switch machine is the actuator of the track control system. The speed-up track circuit matched with S700K is mainly divided into three parts, namely the indoor track control circuit, the track action circuit and the track indication circuit, a total of five-wire circuits, and the indoor and outdoor contactors each have 5 wires. 1.2 Features This product adopts a cabinet structure based on field application and combined with actual teaching characteristics. It integrates the three-part control circuit of S700K into one cabinet to realize all functions of the speed regulation track circuit. At the same time, it also concentrates the electrical circuit on 6502 to form a complete electrical combination circuit, which can allow students to have an overall understanding of the track control circuit, master the working principle of the track control circuit, and skillfully perform related circuit connection and troubleshooting. This product is equipped with control power supply, display power supply, DB instruction, FB instruction, HD instruction, related status display, voltage, current measurement loop, etc., involving contents: DBQ, BHJ, 1DQJ, 1DQJF, 2DQJ, DBJ, FBJ, QDJ, SJ, RC, etc. II.Performance Parameter 2.1 Technical Parameters Power supply parameters: three-phase five-wire AC 380V ±10% 60Hz 2.2 Dimensions and Weight Size1 : 840mm x 720mm x 1970mm Weight1 : <173kg Size2 : 1250mm x 550mm x 780mm Weight2 : <150kg III.Components List and Detailed Introduction 3.1 Main Part Number Name 1 DC ammeter 2 DC voltmeter 3 AC ammeter 4 AC voltmeter 5 Switch 6 AC power indicator 7 AC power indicator 8 AC power indicator 9 DC power indicator 10 DB indicates power indicator 11 Adjacent track has car relay indicator 12 Positioning indicator indicator 13 Four-open position indicator indicator 14 Reverse position indicator indicator 15 Cut relay indicator 16 Track has car simulation operation button 17 Positioning start button 18 BHJ indicator 19 Reverse position start button 20 Cut simulation operation button 3.2 Electrical parts inside the cabinet Number Name 1 4P circuit breaker 2 2P circuit breaker 3 Phase failure protector 4 Protection relay 5 1 switch start relay 6 1 switch repeater relay 7 2 switch start relay 8 DBJ position indication relay 9 FBJ reverse position indication relay 10 Adjacent track vehicle relay 11 QDJ cut-off relay 12 TJ time relay 3.3 Accessories Number Name Function Introduction 1 Fuse core 5A Protection circuit 2 Fuse core 1A Protection circuit IV Product Configuration List Number Name Quantity 1 MR081E Advanced Rail Control Circuit Training Console 1 2 Switch machine 1 3 Fuse core 5A 5 4 Fuse core 1A 5 V.Experiment List Experiment 1 Power-on operation test Experiment 2 Track operation test
