Product function

The signal relay is an important element in the interlocking equipment, and it is the main equipment to ensure the safe operation of the system. The signal relay can control the conversion, lock and unlock the way of the road meeting, and control the opening and closing of the signal machine. Its reliability, availability, maintainability and the entire sauna line are the keys to the safety of railway transportation and operational services.


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.


Product electrical life

The ordinary contact of the relay is connected to DC24V1A resistive load; the strengthened contact is connected to DC220V7.5A, 0.05H inductive load, and its electrical life is 1×105. Installation precautions

1. When installing the relay, make sure that the perfect interval in the middle of the socket 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 same set 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.


maintenance

Daily maintenance and maintenance items are as follows:

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.


Regular maintenance

In the electrical life and life management cycle of the relay, the maintenance cycle of the stepless relay and the rectifier relay should be five years;

The overhaul period of stepless enhanced contact relays, poled relays and biased pole relays should be three years;

The overhaul period of stepped reinforced contact relays should be one year.

Appearance inspection and performance inspection should be carried out after the overhaul.


Packaging, transportation, storage

(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.

(3) Storage conditions, storage period and precautions

The relay should be stored in a well-ventilated warehouse with a temperature of -25°C, 10-40°C, a relative humidity of less than 80%, and no acid, alkali or other harmful gases around. It should not be exposed to rain and snow during storage.

The storage period is one year, and the storage period should be inspected or repaired before use.
