Product Introduction

The JYXC-270 poled relay is an important component 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. 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 JYXC-270 poled relay is used in the signal circuit to automatically block the direction relay in the single-wire automatic blocking and change the direction of operation circuit.

Features

1. The relay is designed according to the needs of the bistable circuit in the signal circuit. Permanent magnets are added to the magnetic circuit system of the relay, so that the relay has two stable states of positioning and reverse due to the different polarity of the current in the coil. These two stable states can continue to be maintained after the current in the coil disappears.

2. The use of silver-silver oxidation requires contacts, which has the characteristics of strong anti-adhesion and low contact resistance.

3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and a stop piece is installed 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.

4. The contact system is composed of ordinary contacts, with four groups of positioning and reverse conversion ordinary contacts.

5. The rated current of the relay is DC 48mA.

Installation precautions|

(1) When installing the relay, make sure that the insulation interval between the sockets is intact, the socket hanging spring is intact, and that the socket identification pin is in the correct position and should not be missing.

(2) Pay attention to the relative position between the relay and the socket when broadcasting the relay to avoid damage to the relay or socket during broadcasting.

(3) When repairing and 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.

Insulation withstand voltage

Under the standard atmospheric conditions of the test, the insulation resistance of the relay should not be less than 100MQ.

Under the condition that the air pressure is not less 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 1 min, and the voltage during repeated test should be 75% of the original test voltage.
