Product Introduction JPXC-1000 biased pole relay is an important component in interlocking equipment and the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the turnout, lock and unlock the way, and control the opening and closing of the signal machine. Relays are widely used in railway signal technology, called signal relays, which are important components in railway signal technology. It plays an important role no matter as the core component of the relay signal system or as the interface component of the electronic or computer signal system. The reliability of the relay action directly affects the reliability and safety of the signal system. Product Usage The JPXC-1000 biased pole relay is designed to identify the polarity of the current in the signal circuit. In the signal circuit, it is used in the turnout indication circuit and the single-multiplex semi-automatic blocking circuit. Features 1. The relay adds a pole-biased magnet to the magnetic circuit, so that the armature is biased to the drop position by the permanent magnetic force. The pull-up of the armature is related to the polarity of the current in the coil. When the current through the coil is in the specified direction, the armature is pulled up, and when the direction of the current is opposite, the armature remains stationary. It only has a stable state, that is, after the armature is sucked up by electromagnetic force, it will fall when the power is cut off, and it will always be in a falling positioning state. 2. The relay is a heavy spring force DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is powered off. 3. It adopts silver-silver cadmium oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance. 4. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay. 5. The relay contact system is composed of ordinary contacts, with 8 groups of ordinary moving on and moving off conversion contacts. 6. The rated voltage of the relay is DC 24V.
Product Usage The JC type AC relay is used as a buck-boost control relay, a signal switch track power supply supervisory relay, and a main screen and a backup screen conversion relay in the power supply screen. Can replace JZXC-20000 rectifier relay. Features 1. The relay is an AC 220V heavy spring force electromagnetic relay with reinforced contacts. 2. The relay magnetic system is a clap-on AC magnetic system, which is composed of an iron core, a coil and an armature. 3. It adopts silver-silver oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance. 4. The contact system is composed of ordinary contacts. There are four groups of moving on and off conversion ordinary contacts and two groups of moving and closing ordinary contacts. The structure of the ordinary contacts is the same as that of a non-polar relay. Applicable environment a) Ambient temperature: -40~+60; b) Relative humidity: not more than 90% (temperature +25C); c) Air pressure: not less than 70kPa (equivalent to an altitude below 3000m); d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm; e) Working position: horizontal; f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken. Dimensions
Executive standard GB/T7417-2010 "Railway Signal AX Series Relay" product structure The electromagnetic system of the stepless enhanced contact slow release relay is the same as that of the stepless slow release relay (JWXC-H340). The magnetic circuit system of the JWJXC-H125/80 stepless enhanced contact slow release relay adds a copper short-circuit ring to make the slow release time longer. The contact system consists of two parts: ordinary contacts and enhanced contacts. The structure of ordinary contacts is the same as that of non-polar relays, and the reinforced contacts are specially designed high-power contacts and arc wave devices. Product Usage The transmission relay is one of the important equipment in the AC counting code automatic blocking equipment. The DC pulse sent by the electric code transmitter is transformed into an AC pulse by the relay, and then sent to the track circuit. JCZC2-2000 transmission relay is used in the station. Features Heavy spring force relay. It is necessary to install a shock absorber when in use. Mechanical properties Number of contact groups: 2QHJ; 2QH Identification pin number: 14, 53; Strengthen the contact gap: not less than 1.5mm; Ordinary contact gap: not less than 0.8mm; Strengthen the contact pressure: the front contact is not less than 450mN; the rear contact is not less than 450mN; Ordinary contact pressure: the front contact is not less than 250mN; the rear contact is not less than 250mN; The air gap between the iron core and the street iron when the relay is working: not more than 0.20mm. Strengthen the contact pressure on the transmission rod: not less than 100mN. Strengthen the joint travel: not less than 0.1mm. Common travel of common contacts: not less than 0.25mm.

3. When repairing or replacing the relay, first remove the national relay spring, and then pull out the relay. Do not use excessive force or shake left and right when pulling it out, as it may damage the relay or socket. Faults and troubleshooting methods 1. The relay contact has no output The analysis and elimination methods of the relay contact without output are as follows: (1) Make sure that the relay and socket should be reliably plugged in; (2) Check that the relay should not be mechanically blocked. If foreign matter in the relay blocks the armature, the armature cannot work reliably (forward rotation) or release (reverse rotation), and the contacts cannot be reliably contacted; (3) Check that there should be no foreign matter between the contacts, there is foreign matter between the contacts, and the contacts cannot be reliably contacted; (4) Check that the contact resistance of the relay contact should not be too large. 2. The relay does not work or the relay with a pole cannot be reversed in the forward direction be reliably released.
