Test method

Requirements for testing measuring tools, meters, and power supply

(1) the accuracy of the measuring tool for measuring the shape 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%.

(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

(3) 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.

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 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 relay spring set in the garden, 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

1. the 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.

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

3. the relay does not release

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.

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.
