JYXC-660 Pole Relay

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.

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.

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.
