Product Introduction

JZXC-H142 tyPE rectifier slow release relay is an important component in interlocking equipment. It is 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 control the opening and closing of the signal machine, etc.. Its reliability, availability, maintainability and the entire sauna line are the keys to the safety of railway transportation and operation services. the automatic control systems in various fields all use relays.

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 electrical life

the relay contacts are connected to DC24V1A resistive load; its electrical life is 1106 times.

Product structure

the electromagnetic system of the rectifier relay is the same as that of the infinite relay. Only the magnetic circuit structure parameters are different. It is mainly to install a half-wave or full-wave rectifier circuit composed of diodes above the contact group.

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 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.

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 plugging in the relay to avoid damage to the relay or socket during plugging.

(3) When repairing and replacing the relay, first remove the fixed 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

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 a foreign object 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. the relay does not work or the relay with a pole cannot be reversed in the forward direction

the relay does not work or the relay with a pole cannot be reversed in the forward direction. the analysis and troubleshooting methods are as follows:

(1) Make sure that the relay and socket should be reliably plugged in;

(2) Check that the input voltage or current of the relay coil should be the rated value or the system circuit adjustment value.

Method: Use a multimeter to check the voltage relay coil input terminal voltage on the socket should meet the output voltage of the power supply screen; use a multimeter to check the voltage drop of the current relay coil input terminal on the socket should meet the voltage drop requirements of the system circuit for reliable operation of the relay; otherwise, system error;

(3) If the above two items are normal, it can be determined that the relay is faulty and the relay should be replaced;

(4) the relay coil is short-circuited or disconnected, the relay cannot work reliably or has a pole relay;

(5) the diode of the rectifier relay is impacted or short-circuited, and the rectifier relay cannot work reliably;

(6) Check that the relay should not be mechanically blocked. If the foreign matter in the relay blocks the iron, the relay cannot work reliably or reverse polarity.

Daily maintenance and maintenance

A) Keep the relay and socket clean;

B) Observe whether the relay operation status is normal;

C) the relay should be replaced in time for abnormal operating conditions and serious contact burnout.

(1) Packaging

the outer packaging of the relay adopts a carton structure, and the carton is equipped with a foam box to ensure that the relay will not damage the instruction manual of the relay in each packaging box during the normal transportation process.

(2) Precautions for transportation

during storage and transportation, the relay should not be subjected to strong vibrations, collisions, or rain or snow.
