Product Usage

The transmission relay is one of the important equipment in the AC counting code automatic blocking equipment. The DC pulse sent by the electric code transmitter is transformed into an AC pulse by the transmission relay, and then sent to the track circuit.

JCZC1-72 transmission relay is used for automatic blocking interval.

 

Features

Heavy spring force relay.

 

Dimensions

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

 

Installation method

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

Relay identification pin numbers 13, 53.

 

Applicable environment

a) Ambient temperature: -40℃~+60℃;

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

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.
