Product Usage The JWJXC-7200 type stepless enhanced contact relay is used as a power supply supervisory relay for the electric point machine in the power supply screen of a large station. Product function JWJXC-7200 type stepless enhanced contact relay is a commonly used electrical appliance in automatic control systems. It is used to connect and disconnect circuits, to issue control commands and reflect the status of equipment to form automatic control and remote control circuits. Applicable environment The applicable environment of the relay is: 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. product structure The electromagnetic system of the stepless strengthened contact relay is a stepless magnetic circuit with an enlarged size. The contact system is composed of two parts: a normal contact and a strong contact. The normal contact is the same as the stepless relay. Switches, switch start, etc.) designed contacts and isolator. Mechanical properties Number of contact groups: 4QJ; 2H Identification pin number: 14, 55; Strengthen the contact gap: not less than 7mm; Ordinary contact gap: not less than 4.5mm; Reinforce the gap of the support plate: generally not less than 0.35mm; Reinforce the gap of the support: the reinforcement is not less than 0.1-0.3mm;
