Jjjc1 Ac Enhanced Contact Relay

Product Introduction The JJJC7 AC enhanced contact relay is an important element in the interlocking equipment and the main equipment to ensure the safe operation of the system. The signal relay can control the switching, locking and unlocking of the turnout, and 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 JJC7 AC enhanced contact relay is used in the distributed power supply screen. Features 1. The JJJC7 type relay is an AC 220V heavy spring force type reinforced contact electromagnetic relay. 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. The use of silver-silver oxidation requires contacts, which has the characteristics of strong anti-adhesion and low contact resistance. 4. The relay contact system consists of two parts: ordinary contacts and enhanced contacts. There are two groups of moving on and off switching ordinary contacts; the two sets of moving on and off switching enhanced contacts, the structure of the ordinary contacts is the same as the stepless relay, and the strengthened contacts Specially designed high-power contacts. 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. Insulation withstand voltage Under the standard atmospheric conditions of the test, the absolute resistance of the relay should not be less than 100MQ. Under the condition that the air pressure is not lower than 86kPa (equivalent to the altitude below 1000m), the insulation withstand voltage of the relay should be able to withstand AC sine wave 50Hz, 2000V rms voltage, there should be no breakdown flashover after 1min, the voltage when repeating the test Should be 75% of the original test voltage value.

Product Introduction The JJJC5 AC enhanced contact relay is an important element in the 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.
