JYXC-660 pole relay
  • Product Details

Product Introduction

The JYXC-660 poled 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 route, 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. The automatic control systems in various fields all use relays.


Product Usage

The JYXC-660 poled relay is used as a general poled relay in the signal circuit.


Applicable environment

The applicable environment of the relay is:

a) Ambient temperature: -40℃~+60℃;

b) Relative humidity: not more than 90% (temperature +25℃);

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 function

The JYXC-660 poled 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.

Electrical characteristics

Coil resistance: 330 (1±10%) Ω×2

The coils are connected in series, connect 2, 3, use 1, 4;

Rated value: DC24V;

Magnetizing value: DC60V;

The extreme value of rotation: 10V~15V;

Contact resistance: not more than 0.05Ω.


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 relay contact system consists of common contacts, with six groups of common contacts for positioning and reverse conversion.

4. The rated voltage of the relay is DC 24V.


test method

Standard test conditions:

Temperature: +15℃~+45℃;

Relative humidity: 45%~75%

Air pressure: 86kPa~106kPa

Requirements for testing measuring tools, meters, and power supply:

The accuracy of the measuring tool for measuring appearance and installation dimensions should not be less than 0.05mm; the accuracy of the feeler gauge should not be less than level 2; the measurement error of the force measurement should not be greater than 2%. The accuracy of the DC voltmeter and ammeter used for testing should not be less than 0.5, and the accuracy of the AC (50Hz) voltmeter and ammeter should not be less than 1. The power supply voltage should remain stable, and its fluctuation range should not exceed 5%. The DC power supply should be a DC generator, battery or AC full-wave rectifier power supply (except for special regulations, the ripple factor should not be greater than 5%). The waveform of the AC power supply should be a sine wave with a frequency of 50 Hz.

Relay: 165mm×49mm×163mm (length×width×height)

Socket: 157mm×48mm×22mm (length×width×height)


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 foreign matter 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

(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 relay; use a multimeter to check the current relay coil input terminal voltage drop on the broadcast base should meet the voltage drop requirements for the reliable operation of the relay in the system circuit; otherwise Is a system failure;

(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 a foreign object in the relay blocks the armature, the relay cannot work reliably or reverse poles in the forward direction.


The relay is not released or the relay with a pole cannot be reversed in the forward direction

The relay non-release 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 meet the requirements of the system circuit for reliable release of the relay.

Method: Use a multimeter to check that the voltage relay coil input terminal voltage on the socket should be less than the release voltage of the relay; use a multimeter to check that the voltage drop of the current relay coil input terminal on the socket should meet the requirements for reliable release of the relay in the system circuit; otherwise, it is a system failure;

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

(4) Check that the relay should not be mechanically blocked. If a foreign object in the relay blocks the armature, the relay cannot be reliably released.


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.


Installation method

The relay socket is installed on the combination frame (cabinet) with bolts, and the relay is horizontally inserted into the socket and clamped with a hanging spring.

Relay identification pin numbers 15, 52.


Product electrical life

The relay contacts are connected to DC24V1A resistive load; its electrical life is 4×105 times.


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.
