  • Product Details

product description

There is a pole strengthened contact relay: JYJXC-220/220


Product Features

The JVJXC-220/220 type has a pole reinforced contact relay used as a two-start relay in the signal switch control circuit.


Product Usage

The JVJXC-220/220 type has a pole reinforced contact relay used as a switch control relay in a signal circuit.


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 is composed of common contacts and reinforced contacts. There are two sets of positioning and reverse conversion common contacts, and two sets of positioning and reverse conversion reinforced contacts with arc-extinguishing magnets. The strengthened contact of the relay is specially designed for turning on the high current of the switch point machine.

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


Applicable environment

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.

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.


Insulation withstand voltage

Under the standard atmospheric conditions of the test, the absolute resistance of the relay should not be less than 100MΩ.

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.


Product electrical life

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